The A to Z of OneSecond Ingredients


Vitamin A is a fat-soluble vitamin that is naturally present in many foods.

Why does my body need it?

Vitamin A is important for normal vision, the immune system, and reproduction. Vitamin A also helps the heart, lungs, kidneys, and other organs work properly.

There are two different types of vitamin A. The first type, preformed vitamin A, is found in meat, poultry, fish, and dairy products. The second type, provitamin A, is found in fruits, vegetables, and other plant-based products. The most common type of provitamin A in foods and dietary supplements is beta-carotene.

Vitamin A deficiency is rare in the United States, although it is common in many developing countries. The most common symptom of vitamin A deficiency in young children and pregnant women is an eye condition called xerophthalmia. Xerophthalmia is the inability to see in low light, and it can lead to blindness if it isn’t treated.

How can I get it?

  • Beef liver and other organ meats (but these foods are also high in cholesterol, so limit the amount you eat).
  • Some types of fish, such as salmon.
  • Green leafy vegetables and other green, orange, and yellow vegetables, such as broccoli, carrots, and squash.
  • Fruits, including cantaloupe, apricots, and mangos.
  • Dairy products, which are among the major sources of vitamin A for Americans.
  • Fortified breakfast cereals.

Am I at risk for deficiency?

The following groups of people are at a higher risk for deficiency:

  • Premature infants, who often have low levels of vitamin A in their first year.
  • Infants, young children, pregnant women, and breastfeeding women in developing countries.
  • People with cystic fibrosis.

OneSecond Supplements sprays that contain Vitamin A:


Thiamin (also called vitamin B1) is one of the 8 B vitamins. It helps turn the food you eat into the energy you need.

Why does my body need it?

Thiamin is important for the growth, development, and function of the cells in your body.

You can develop thiamin deficiency if you don’t get enough thiamin in the foods you eat or if your body eliminates too much or absorbs too little thiamin.

Thiamin deficiency can cause loss of weight and appetite, confusion, memory loss, muscle weakness, and heart problems. Severe thiamin deficiency leads to a disease called beriberi with the added symptoms of tingling and numbness in the feet and hands, loss of muscle, and poor reflexes. Beriberi is not common in the United States and other developed countries.

A more common example of thiamin deficiency in the United States is Wernicke-Korsakoff syndrome, which mostly affects people with alcoholism. It causes tingling and numbness in the hands and feet, severe memory loss, disorientation, and confusion.

How can I get it?

Food sources of thiamin include beef, liver, dried milk, nuts, oats, oranges, pork, eggs, seeds, legumes, peas and yeast.

Foods are also fortified with thiamin. Some foods that are often fortified with B1 are rice, pasta, breads, cereals and flour.

Am I at risk for deficiency?

Most people in the United States get enough thiamin from the foods they eat. Thiamin deficiency is rare in this country. However, certain groups of people are more likely than others to have trouble getting enough thiamin:

  • People with alcohol dependence
  • Older individuals
  • People with HIV/AIDS
  • People with diabetes
  • People who have had bariatric surgery

Talk with your health care provider(s) about thiamin and other dietary supplements to help you determine which, if any, might be valuable for you.


Riboflavin (also called vitamin B2) is one of the 8 B vitamin complexes.

Why does my body need it?

It is important for the growth, development, and function of the cells in your body. It also helps turn the food you eat into the energy you need.

You can develop riboflavin deficiency if you don’t get enough riboflavin in the foods you eat, or if you have certain diseases or hormone disorders.

Riboflavin deficiency can cause skin disorders, sores at the corners of your mouth, swollen and cracked lips, hair loss, sore throat, liver disorders, and problems with your reproductive and nervous systems.

Severe, long-term riboflavin deficiency causes a shortage of red blood cells (anemia), which makes you feel weak and tired. It also causes clouding of the lens in your eyes (cataracts), which affects your vision.

Migraine headache
Some studies show that riboflavin supplements might help prevent migraine headaches, but other studies do not. Riboflavin supplements usually have very few side effects, so some medical experts recommend trying riboflavin, under the guidance of a health care provider, for preventing migraines.

How can I get it?

  • Eggs, organ meats (such as kidneys and liver), lean meats, and low-fat milk
  • Green vegetables (such as asparagus, broccoli, and spinach)

Am I at risk for deficiency?

Most people in the United States get enough riboflavin from the foods they eat and deficiencies are very rare. However, certain groups of people are more likely than others to have trouble getting enough riboflavin:

  • Athletes who are vegetarians (especially strict vegetarians who avoid dairy foods and eggs)
  • Pregnant women and breastfeeding women and their babies
  • People who are vegan
  • People who do not eat dairy foods
  • People with a genetic disorder that causes riboflavin deficiency (such as infantile Brown-Vialetto-Van Laere syndrome)


Niacin (also known as Vitamin B3) is one of the 8 B vitamins.

Why does my body need it?

Niacin plays a role in converting the food we eat into energy. It helps the body to use proteins and fats, and it keep the skin, hair, and nervous system healthy.

It may also reduce cardiovascular risk, because it can be used to help lower cholesterol. There is some evidence that it may reduce blood pressure because it is a vasodilator.

How can I get it?

Niacin (also known as vitamin B3) is found in:

  • Milk
  • Eggs
  • Enriched breads and cereals
  • Rice
  • Fish
  • Lean meats
  • Legumes
  • Peanuts
  • Poultry

Am I at risk for deficiency?

Niacin deficiency is quite rare in the USA. Nicain is used to help manage cholesterol. For many years, doses of 1 to 3 grams of nicotinic acid per day has been a treatment option for low HDL cholesterol and high LDL cholesterol and triglyceride levels.

A deficiency of niacin causes pellagra. The symptoms include:

  • Digestive problems
  • Inflamed skin
  • Mental impairment

Large doses of niacin can cause:

  • Increased blood sugar (glucose) level
  • Liver damage
  • Peptic ulcers
  • Skin rashes


Pantothenic Acid is also known as Vitamin B5 and is one of the 8 B vitamin complexes.

Why does my body need it?

Pantothenic acid and biotin are needed for growth. They help the body break down and use food. This is called metabolism. They are both required for making fatty acids.

Pantothenic acid also plays a role in the production of hormones and cholesterol. It is also used in the conversion of pyruvate.

Pantothenic acid deficiency is very rare, but can cause a tingling feeling in the feet (paresthesia). Biotin deficiency may lead to muscle pain, dermatitis, or glossitis (swelling of the tongue). Large doses of pantothenic acid do not cause symptoms, other than (possibly) diarrhea.

How can I get it?

  • Animal proteins
  • Avocado
  • Broccoli, kale, and other vegetables in the cabbage family
  • Eggs
  • Legumes and lentils
  • Milk
  • Mushrooms
  • Organ meats
  • Poultry
  • White and sweet potatoes
  • Whole-grain cereals
  • Yeast

Am I at risk for deficiency?

Risk of deficiency is low however groups that may be at higher risk include:

  • Alcoholics
  • Women on oral contraceptives
  • The elderly
  • People with impaired absorption due to certain digestive disorders

OneSecond Supplements sprays that contain Vitamin B5:


Vitamin B6 is one of the 8 B vitamins complexes.

Why does my body need it?

The body needs vitamin B6 for more than 100 enzyme reactions involved in metabolism. Vitamin B6 is also involved in brain development during pregnancy and infancy as well as immune function.

Vitamin B6 deficiency is uncommon in the United States. People who don’t get enough vitamin B6 can have a range of symptoms, including anemia, itchy rashes, scaly skin on the lips, cracks at the corners of the mouth, and a swollen tongue. Other symptoms of very low vitamin B6 levels include depression, confusion, and a weak immune system. Infants who do not get enough vitamin B6 can become irritable or develop extremely sensitive hearing or seizures.

How can I get it?

  • Poultry, fish, and organ meats, all rich in vitamin B6.
  • Potatoes and other starchy vegetables, which are some of the major sources of vitamin B6 for Americans.
  • Fruit (other than citrus), which are also among the major sources of vitamin B6 for Americans.

Am I at risk for deficiency?

Most people in the United States get enough vitamin B6 from the foods they eat. However, certain groups of people are more likely than others to have trouble getting enough vitamin B6:

  • People whose kidneys do not work properly, including people who are on kidney dialysis and those who have had a kidney transplant.
  • People with autoimmune disorders, which cause their immune system to mistakenly attack their own healthy tissues. For example, people with rheumatoid arthritis, celiac disease, Crohn’s disease, ulcerative colitis, or inflammatory bowel disease sometimes have low vitamin B6 levels.
  • People with alcohol dependence.

OneSecond Supplements sprays that contain Vitamin B6:


Vitamin B12, is one of the eight B vitamin complexes.

Why does my body need it?

Vitamin B12 plays a vital role in the normal functioning of the brain and the nervous system and in the formation of red blood cells. It also helps to regulate and synthesize DNA.

By helping the human body to absorb folic acid, it facilitates the release of energy.

How can I get it?

Naturally found in animal products, does not typically occur in plant based foods.

  • Meat and poultry
  • Fish
  • Dairy products such as milk and cheese
  • Some nutritional yeast products
  • Eggs

Am I at risk for deficiency?

The following groups of people are at a higher risk for deficiency:

  • Vegans
  • Vegetarians
  • Older adults
  • People with pernicious anemia
  • People taking certain medication such as metformin and proton pump inhibitors (PPI)/ H2 receptor antagonists
  • People suffering from inflammatory bowl disease/ crohn’s gastritis, celiac disease, gastric surgery
  • Alcohol – B12 deficiency is endemic in alcoholics

OneSecond Supplements sprays that contain Vitamin B12:


Caffeine is a central nervous system stimulant. It is the most widely consumed stimulant in the world.

The body does not 'require'

Why does my body need it?

Caffeine but this highly active substance can be extremely aid for daily life.

Caffeine has a poor reputation in the media but the truth is that Caffeine in moderation itself is actually very good for you. Additional ingredients in Energy shots and drinks including large amounts of sugar, taurine, tyrosine and phenylalanine can have negative effects on your health.

How can I get it?

Caffeine is naturally found in Coffee, Tea and chocolate and is added to soft drinks like Cola and energy drinks.

Am I at risk for deficiency?

No one is ever deficient in Caffeine but its use may be helpful in many populations especially in low controllable doses.

Caffeine in moderation has shown health benefits with:

  • Mental acuity improvement
  • Memory improvement
  • Reduced risk of Alzheimers disease
  • Reduced risk of Strokes in older patients
  • Reduction in risk of Parkinsons disease
  • Reduced risks of heart disease
  • Aids fat loss by increasing fat burn by 15% for up to 3 hours after exercise
  • Reduce muscle pain and injury
  • Lowers risk of type 2 diabetes
  • Improves reaction times
  • Improves the efficacy of Painkillers when combined with them
  • Reduced risk of Oral and Throat cancer


Vitamin D is a fat-soluble vitamin that is naturally present in very few foods, added to others, and available as a dietary supplement. It is also produced endogenously when ultraviolet rays from sunlight strike the skin and trigger vitamin D synthesis.

Why does my body need it?

Vitamin D deficiency is associated with:

  • Osteoporosis and Osteopenia
  • 17 varieties of Cancer (including breast, prostate and colon)
  • Heart disease
  • High blood pressure
  • Obesity
  • Metabolic Syndrome and Diabetes
  • Autoimmune diseases
  • Multiple sclerosis
  • Rheumatoid arthritis
  • Osteoarthritis
  • Bursitis
  • Gout
  • Infertility and PMS
  • Parkinson’s Disease
  • Depression and Seasonal Affective Disorder
  • Alzheimer’s Disease
  • Chronic fatigue syndrome
  • Fibromyalgia
  • Chronic Pain
  • Periodontal disease
  • Psoriasis

How can I get it?

Vitamin D is naturally present in very few foods and often added to others. It is available as a dietary supplement. Vitamin D obtained from sun exposure, food, and supplements is biologically inert and must undergo two hydroxylations in the body for activation. The first occurs in the liver and converts vitamin D to 25-hydroxyvitamin D [25(OH)D], also known as calcidiol. The second occurs primarily in the kidney and forms the physiologically active 1,25-dihydroxyvitamin D [1,25(OH)2D], also known as calcitriol.

Am I at risk for deficiency?

The USA is in the midst of a ‘Vitamin D Deficiency pandemic’ – NHANES (National Health and Nutritional Examination Survey – CDC) shows that 70% of the US population do not achieve 16ng/ml of Vitamin D. This rises to over 95% of the US population when the ideal level of 50ng/ml is considered.
This level of serum vitamin D is very difficult to achieve in the USA and is usually only seen in equatorial regions. Combined with time spent indoors and the blockage of UV rays by clothing and sunscreen supplementation should be universal.

The current RDA of 600iu per day is considered low and the bioavailabilty of vitamin D from tablets and gummies may prevent optimal serum levels.

Vitamin D supplementation should be considered in everyone. It is especially important in children, adolescents, pregnancy and the elderly.

OneSecond Supplements sprays that contain Vitamin D:


Vitamin E is a fat-soluble nutrient found in many foods. Vitamin E from natural (food) sources is commonly listed as ”d-alpha-tocopherol” on food packaging and supplement labels. Synthetic (laboratory-made) vitamin E is commonly listed as ”dl-alpha-tocopherol.” The natural form is more potent.

Why does my body need it?

In the body, it acts as an antioxidant, helping to protect cells from the damage caused by free radicals. Free radicals are compounds formed when our bodies convert the food we eat into energy. People are also exposed to free radicals in the environment from cigarette smoke, air pollution, and ultraviolet light from the sun.

The body also needs vitamin E to boost its immune system so that it can fight off invading bacteria and viruses. It helps to widen blood vessels and keep blood from clotting within them. In addition, cells use vitamin E to interact with each other and to carry out many important functions.

How can I get it?

Vegetable oils like wheat germ, sunflower, and safflower oils are among the best sources of vitamin E. Corn and soybean oils also provide some vitamin E.

Nuts (such as peanuts, hazelnuts, and, especially, almonds) and seeds (like sunflower seeds)

Green vegetables, such as spinach and broccoli, provide some vitamin E.

  • Food companies add vitamin E to some breakfast cereals, fruit juices, margarines and spreads, and other foods. To find out which ones have vitamin E, check the product labels.

Am I at risk for deficiency?

Vitamin E deficiency is very rare in healthy people. It is almost always linked to certain diseases where fat is not properly digested or absorbed. Examples include Crohn’s disease, cystic fibrosis, and certain rare genetic diseases such as abetalipoproteinemia and ataxia with vitamin E deficiency (AVED). Vitamin E needs some fat for the digestive system to absorb it.

Vitamin E deficiency can cause nerve and muscle damage that results in loss of feeling in the arms and legs, loss of body movement control, muscle weakness, and vision problems. Another sign of deficiency is a weakened immune system.

Vitamin E dietary supplements can interact or interfere with certain medicines that you take. Here are some examples:

  • Vitamin E can increase the risk of bleeding in people taking anticoagulant or antiplatelet medicines, such as warfarin (Coumadin®).
  • In one study, vitamin E plus other antioxidants (such as vitamin C, selenium, and beta-carotene) reduced the heart-protective effects of two drugs taken in combination (a statin and niacin) to affect blood-cholesterol levels.
  • Taking antioxidant supplements while undergoing chemotherapy or radiation therapy for cancer could alter the effectiveness of these treatments.

Tell your doctor, pharmacist, and other health care providers about any dietary supplements and medicines you take. They can tell you if those dietary supplements might interact or interfere with your prescription or over-the-counter medicines, or if the medicines might interfere with how your body absorbs, uses, or breaks down nutrients.

OneSecond Supplements sprays that contain Vitamin E:


Folate is a B-vitamin that is naturally present in many foods. A form of folate, called folic acid, is used in dietary supplements and fortified foods.

Why does my body need it?

Our bodies need folate to make DNA and other genetic material. Folate is also needed for the body’s cells to divide.

Folate deficiency is rare in the United States, but some people get barely enough. Getting too little folate can result in megaloblastic anemia, which causes weakness, fatigue, trouble concentrating, irritability, headache, heart palpitations, and shortness of breath. Folate deficiency can also cause open sores on the tongue and inside the mouth as well as changes in the color of the skin, hair, or fingernails. Women who don’t get enough folate are at risk of having babies with neural tube defects, such as spina bifida. Folate deficiency can also increase the likelihood of having a premature or low-birth-weight baby.

How can I get it?

  • Vegetables (especially asparagus, Brussels sprouts, and dark green leafy vegetables such as spinach and mustard greens).
  • Fruits and fruit juices (especially oranges and orange juice).
  • Nuts, beans, and peas (such as peanuts, black-eyed peas, and kidney beans).
  • Grains (including whole grains; fortified cold cereals; enriched flour products such as bread, bagels, cornmeal, and pasta; and rice).

Folic acid is added to many grain-based products and corn masa flour (used to make corn tortillas and tamales, for example). To find out whether folic acid has been added to a food, check the product label. Beef liver is high in folate but is also high in cholesterol, so limit the amount you eat. Only small amounts of folate are found in other animal foods like meats, poultry, seafood, eggs, and dairy products.

Am I at risk for deficiency?

The following groups of people are at a higher risk for deficiency:

  • Teen girls and women aged 14–30 years (especially before and during pregnancy).
  • Non-Hispanic black women.
  • People with disorders that lower nutrient absorption (such as celiac disease and inflammatory bowel disease).People with alcoholism.

OneSecond Supplements sprays that contain Folic Acid:


Iodine is a mineral found in some foods.

Why does my body need it?

The body needs iodine to make thyroid hormones. These hormones control the body’s metabolism and many other important functions. The body also needs thyroid hormones for proper bone and brain development during pregnancy and infancy. Getting enough iodine is important for everyone, especially infants and women who are pregnant.

Iodine deficiency is uncommon in the United States and Canada. People who don’t get enough iodine cannot make sufficient amounts of thyroid hormone. This can cause many problems. In pregnant women, severe iodine deficiency can permanently harm the fetus by causing stunted growth, mental retardation, and delayed sexual development. Less severe iodine deficiency can cause lower-than-average IQ in infants and children and decrease adults’ ability to work and think clearly. Goiter, an enlarged thyroid gland, is often the first visible sign of iodine deficiency.

How can I get it?

  • Fish (such as cod and tuna), seaweed, shrimp, and other seafood, which are generally rich in iodine.
  • Dairy products (such as milk, yogurt, and cheese) and products made from grains (like breads and cereals), which are the major sources of iodine in American diets.
  • Fruits and vegetables, which contain iodine, although the amount depends on the iodine in the soil where they grew and in any fertilizer that was used.
  • Iodized salt, which is readily available in the United States and many other countries. Processed foods, however, such as canned soups, almost never contain iodized salt.

Am I at risk for deficiency?

The following groups of people are at a higher risk for deficiency:

  • People who do not use iodized salt. Adding iodine to salt is the most widely used strategy to control iodine deficiency. Currently, about 70% of households worldwide use iodized salt.
  • Pregnant women. Women who are pregnant need about 50% more iodine than other women to provide enough iodine for their baby. Surveys show that many pregnant women in the United States may not get quite enough iodine, although experts do not know whether this affects their babies.
  • People living in regions with iodine-deficient soils who eat mostly local foods. These soils produce crops that have low iodine levels. Among the regions with the most iodine-poor soil are mountainous areas, such as the Himalayas, the Alps, and the Andes regions, as well as river valleys in South and Southeast Asia.
  • People who get marginal amounts of iodine and who also eat foods containing goitrogens. Goitrogens are substances that interfere with the way the body uses iodine. They are present in some plant foods including soy, and cruciferous vegetables such as cabbage, broccoli, cauliflower and Brussels sprouts. For most people in the United States who get adequate amounts of iodine, eating reasonable amounts of foods containing goitrogens is not a concern.

OneSecond Supplements sprays that contain Iodine:


Melatonin is a hormone secreted by the pineal gland in the brain.

Why does my body need it?

Melatonin helps regulate other hormones and maintains the body’s circadian rhythm. The circadian rhythm is an internal 24-hour “clock” that plays a critical role in when we fall asleep and when we wake up. When it is dark, your body produces more melatonin. When it is light, the production of melatonin drops. Being exposed to bright lights in the evening, or too little light during the day, can disrupt the body’s normal melatonin cycles. For example, jet lag, shift work, and poor vision can disrupt melatonin cycles.

How can I get it?

  • Melatonin in endogenously produced from the amino acid L-tryptophan.
  • Exogenous melatonin is only available from supplementation.

Am I at risk for deficiency?

Melatonin production reduces with age.

The primary uses are with:


Studies suggest that melatonin supplements may help people with disrupted circadian rhythms (such as people with jet lag or those who work the night shift), and those with low melatonin levels (such as some seniors and people with schizophrenia) to sleep better. A review of the scientific literature suggests that melatonin supplements may help prevent jet lag, particularly in people who cross 5 or more time zones.

Heart Disease

Several studies show melatonin has cardioprotective properties, including antioxidant and anti-inflammatory effects. Research also suggests that melatonin may help lower blood pressure levels and improve cholesterol profiles.


Melatonin supplements may improve sleep problems associated with menopause. Other studies suggest it may help restore quality of life and prevent bone loss among perimenopausal women.

Benzodiazepine Withdrawal

Some research suggests that melatonin may help elderly people with insomnia who are tapering off or stopping benzodiazepines such as diazepam (Valium), alprazolam (Xanax), or lorazepam (Ativan). Taking melatonin improved sleep quality in those stopping benzodiazepine use.

Breast Cancer

Several studies suggest that low melatonin levels may be associated with breast cancer risk. For example, women with breast cancer tend to have lower levels of melatonin than those without the disease. Laboratory experiments have found that low levels of melatonin stimulate the growth of certain types of breast cancer cells, while adding melatonin to these cells slows their growth. Preliminary evidence also suggests that melatonin may strengthen the effects of some chemotherapy drugs used to treat breast cancer. In a study that included a small number of women with breast cancer, melatonin (given 7 days before beginning chemotherapy) prevented the lowering of platelets in the blood. This is a common complication of chemotherapy that can lead to bleeding.

In another small study of women who were taking tamoxifen for breast cancer but seeing no improvement, adding melatonin caused tumors to modestly shrink in more than 28% of the women.

Prostate Cancer

Studies show that men with prostate cancer have lower melatonin levels than men without the disease. In test tube studies, melatonin blocks the growth of prostate cancer cells. In one small-scale study, melatonin, combined with conventional medical treatment, improved survival rates in 9 out of 14 men with metastatic prostate cancer.

Attention Deficit Hyperactivity Disorder (ADHD) and Autism

Some evidence suggests that melatonin may help promote sleep in children with ADHD or autism.

Fibromyalgia and Chronic Pain

A randomized, placebo-controlled study found that people with fibromyalgia experienced a significant reduction in their symptoms when they took a melatonin supplement either alone or in conjunction with fluoxetine (Prozac). Other studies suggest that melatonin may play a role in other painful conditions, such as migraines.

OneSecond Supplements sprays that contain Melatonin:

There is currently no recommended dose for melatonin supplements. Different people will have different responses to its effects. Lower doses appear to work better in people who are especially sensitive. Higher doses may cause anxiety and irritability.

The best approach for any condition is to begin with very low doses of melatonin. Keep the dose close to the amount that our bodies normally produce (< 0.3 mg per day). You should only use the lowest amount possible to achieve the desired effect.


Selenium is a nutrient that the body needs to stay healthy.

Why does my body need it?

Selenium is important for reproduction, thyroid gland function, DNA production, and protecting the body from damage caused by free radicals and from infection.


Studies suggest that people who consume lower amounts of selenium could have an increased risk of developing cancers of the colon and rectum, prostate, lung, bladder, skin, esophagus, and stomach. But whether selenium supplements reduce cancer risk is not clear. More research is needed to understand the effects of selenium from food and dietary supplements on cancer risk.

Cardiovascular disease

Scientists are studying whether selenium helps reduce the risk of cardiovascular disease. Some studies show that people with lower blood levels of selenium have a higher risk of heart disease, but other studies do not. More studies are needed to better understand how selenium in food and dietary supplements affects heart health.

Cognitive decline

Blood selenium levels decrease as people age, and scientists are studying whether low selenium levels contribute to a decline in brain function in the elderly. Some studies suggest that people with lower blood selenium levels are more likely to have poorer mental function. But a study of elderly people in the United States found no link between selenium levels and memory. More research is needed to find out whether selenium dietary supplements might help reduce the risk of or treat cognitive decline in elderly people.

Thyroid disease

The thyroid gland has high amounts of selenium that play an important role in thyroid function. Studies suggest that people—especially women—who have low blood levels of selenium (and iodine) might develop problems with their thyroid. But whether selenium dietary supplements can help treat or reduce the risk of thyroid disease is not clear. More research is needed to understand the effects of selenium on thyroid disease.

How can I get it?

  • Seafood
  • Meat, poultry, eggs, and dairy products
  • Breads, cereals, and other grain products

Am I at risk for deficiency?

Most Americans get enough selenium from their diet because they eat food grown or raised in many different areas, including areas with soil that is rich in selenium.

Certain groups of people are more likely than others to have trouble getting enough selenium:

  • People undergoing kidney dialysis
  • People living with HIV
  • People who eat only local foods grown in soils that are low in selenium

OneSecond Supplements sprays that contain Selenium:


Zinc is a nutrient that people need to stay healthy.

Zinc deficiency is rare in North America. In children, It causes slow growth in infants and children.

For adults, Zinc deficiency can also cause hair loss, diarrhea, eye, and skin sores and loss of appetite, Weight loss, problems with wound healing, and decreased ability to taste food, and lower alertness levels can also occur.

Many of these symptoms can be signs of problems other than zinc deficiency. If you have these symptoms, your doctor can help determine whether you might have a zinc deficiency.

Why does my body need it?

Zinc is found in cells throughout the body. It helps the immune system fight off invading bacteria and viruses. The body also needs zinc to make proteins and DNA, the genetic material in all cells. During pregnancy, infancy, and childhood, the body needs zinc to grow and develop properly. Zinc also helps wounds heal and is important for proper senses of taste and smell.

Some studies suggest that zinc lozenges or syrup (but not zinc dietary supplements in pill form) help speed recovery from the common cold and reduce its symptoms if taken within 24 hours of coming down with a cold. However, more study is needed to determine the best dose and form of zinc, as well as how long it should be taken before zinc can be recommended as a treatment for the common cold.

How can I get it?

  • Oysters, which are the best source of zinc.
  • Red meat, poultry, seafood such as crab and lobsters.
  • Beans, nuts, whole grains, and dairy products, which provide some zinc.

Am I at risk for deficiency?

The following groups of people are at a higher risk for deficiency:

  • People who have had gastrointestinal surgery, such as weight loss surgery, or who have digestive disorders, such as ulcerative colitis or Crohn’s disease. These conditions can both decrease the amount of zinc that the body absorbs and increase the amount lost in the urine.
  • Vegetarians because they do not eat meat, which is a good source of zinc. Also, the beans and grains they typically eat have compounds that keep zinc from being fully absorbed by the body. For this reason, vegetarians might need to eat as much as 50% more zinc than the recommended amounts.
  • Older infants who are breastfed because breast milk does not have enough zinc for infants over 6 months of age. Older infants who do not take formula should be given foods that have zinc such as pureed meats. Formula-fed infants get enough zinc from infant formula.
  • Alcoholics because alcoholic beverages decrease the amount of zinc that the body absorbs and increase the amount lost in the urine. Also, many alcoholics eat a limited amount and variety of food, so they may not get enough zinc.
  • People with sickle cell disease because they might need more zinc.
