However, a survey published in 2018 found that 40% of Americans are deficient in vitamin D, especially African Americans, people who smoke, those who get little sun exposure or regularly use sunscreen, adults over age 65, and people with obesity or diabetes (3, 4).
Because breast milk contains inadequate amounts of vitamin D, the American Academy of Pediatrics recommends that all breastfed and partially breastfed infants receive 400 IU of vitamin D per day (21).
The best form of vitamin A depends on your personal needs and preferences. Many vitamin A supplements contain preformed vitamin A in the form of retinyl acetate or retinyl palmitate, types of retinol also found in animal products and fortified foods (1).
Vegetarian and vegan vitamin A supplements generally consist of carotenoids, plant-based precursors that are converted into vitamin A in the body. The best-known carotenoid is beta carotene, but there are several others (1).
Older adults and postmenopausal people should also consult a healthcare professional before using vitamin A supplements, as some research suggests that higher intakes of vitamin A could contribute to bone loss (11, 16).
Vitamin D is a nutrient that helps the body take in calcium from the foods that we eat. Together, calcium and vitamin D build bones and keep them strong. Vitamin D also plays a part in heart health and fighting infection.
Our bodies make vitamin D when our skin is exposed to the sun. It's hard to get enough vitamin D from the sun, though. Most kids and adults spend lots of time indoors at school and work. When outdoors, it's important to protect skin to prevent skin cancer and skin damage from too much sun exposure.
Very few foods have vitamin D naturally. The foods with the most are fatty fish (like salmon and tuna), liver, eggs and fish oils. Kids don't eat these foods a lot. That's why food companies add vitamin D to milk, yogurt, baby formula, juice, cereal, and other foods.
Health care providers might order a blood test if they think a health problem is keeping a child from getting enough vitamin D. If doctors don't think your child has a health problem, there's no need for a blood test.
Vitamin D helps the body absorb calcium, a building block for strong bones. Unlike with vitamin D, kids usually can get enough calcium from food. High-calcium foods include milk, cheese, and yogurt. Food makers often fortify foods like cereal, bread, or juice with calcium.
Whether calcium plus vitamin D can prevent fractures has been more controversial, with competing studies on both sides. But a 2016 meta-analysis found that calcium and vitamin D supplements reduced fracture risk by 15% and hip fracture risk by 30%.
Three or more times the recommended amount of vitamin A from animal sources or supplements may increase hip fracture risk. Beta- carotene supplements have been linked to an increased risk of lung cancer in smokers.
What it does: Vitamin B12 is essential for normal brain and nervous system function, to make red blood cells and DNA and to produce energy. B12, along with vitamin B6 and folate, also reduces the amino acid homocysteine, which increases with age and is found at high levels in people with RA.
Research note: High homocysteine is linked to an increased risk of heart attack and stroke as well as bone loss, fractures and cognitive decline in older adults. In 2018, an international panel of experts recommended treatment with B vitamins for all adults who have high homocysteine levels to reduce the risk of memory loss and dementia.
What it does: Also called riboflavin, vitamin B2 converts glucose to energy; may help prevent migraine headaches and cataracts; converts other B vitamins into forms the body can use; is essential for normal cell function and growth; and helps protect against free radical damage, or toxic molecules made in the body that may play a role in cancer, heart disease and aging.
What it does: Vitamin D regulates many critical cellular functions: It aids calcium absorption, helping prevent osteoporosis and fractures; regulates the cells responsible for autoimmune function; fights inflammation, protects against disease-causing germs and helps create a healthy gut microbiome. Adequate amounts are linked to improved heart health. In the body, vitamin D also gets converted to a steroid hormone capable of turning genes on or off, signaling them to make enzymes and proteins crucial to maintaining health and fighting disease.
Vitamins are organic compounds that our bodies use, in very small amounts, for a variety of metabolic processes. It is best to get vitamins and minerals from eating a variety of healthy unprocessed foods.
Phytochemicals are an important component of food and are thought to reduce the incidence of heart disease and some cancers. Supplements do not provide the benefits of phytochemicals and other components found in food. Taking vitamin and mineral supplements is no substitute for a healthy diet.
Our body only needs a small amount of vitamins and minerals every dayExternal Link . A varied diet generally provides enough of each vitamin and mineral. However, some people may need supplements to correct vitamin or mineral deficiencies and this includes:
Folic acid is a B-group vitamin which can also be found in some fortified foods such as breads and breakfast cereals. Foods fortified with folic acid have the nutrient added to them during production to boost their nutritional value.
It is commonly believed that taking mega-doses of certain vitamins will act like medicine to cure or prevent certain ailments. For instance, vitamin C is suggested as a cure for the common cold, and vitamin E is widely promoted as a beneficial antioxidant to help prevent heart disease.
Popping a pill will not likely cure persistent tiredness either. If you are feeling run down, it is more likely to be due to stress, depression, insufficient sleep or other factors, rather than a vitamin deficiency. If you feel like this regularly, seek medical advice.
Vitamin E is often singled out as the potential fountain of youth. However, there is no evidence that taking large doses of any vitamin can stall or reverse the effects of ageing. Neither can one vitamin restore a flagging sex drive or cure infertility.
Proper balance and adequate levels of essential nutrients is important for a range of complex processes in our body. When vitamins are taken as supplements, they are introduced into the body at levels that could never be achieved by eating even the healthiest of diets.
Vitamin and mineral supplements can also interfere with prescription medicines and medical treatments. In extreme cases, for example, where people take 100 times the recommended dietary intake (RDI), this can stop the work of anticonvulsant drugs, such as those used in epilepsy.
If you feel that you could be lacking in certain vitamins and minerals, it may be better to look at changing your diet and lifestyle rather than reaching for supplements. If you need help, see your doctor or a dietitian.
Inadequate or deficient levels of vitamin D can be a problem because vitamin D can help the gut absorb calcium, which ultimately promotes strong and healthy bones. Vitamin D is also helpful in reducing inflammation and boosting immune function and cell growth. (3)
Nor was vitamin D supplementation found to reduce the risk of cancer, heart attack, stroke, or cardiovascular death in a randomized, controlled clinical trial involving more than 25,000 participants from 2019. (5) Yet researchers found that those who developed cancer had a 25 percent lower death rate when they were taking vitamin D. The findings also included a possible reduction in cancer risk for African Americans, which researchers wrote warrants further study.
Meanwhile, though observational studies have suggested a link between low vitamin D levels and the risk of developing type 2 diabetes, another randomized, controlled clinical trial published in 2019 did not support that conclusion. (6) Vitamin D3 supplementation at a dose of 4,000 IU per day did not result in a significantly lower risk of diabetes compared with a placebo.
You can either get the B12 on its own, go with the B complex (which contains all of the B vitamins like riboflavin and biotin), or add on other supplements like ashwagandha, collagen, and probiotics.
Why we chose it: If you want a great-tasting supplement, add this to your medicine cabinet stat. Reviewers love the raspberry flavor, and the gummy form makes taking this vitamin a little more of a treat.
Luckily, supplementing with vitamin B12 can improve your B12 levels, which can contribute to a healthy pregnancy, fetal/neonatal brain development, and improved bone health, mood, memory, and energy.
As you get older, your body starts to produce less stomach acid, which is needed to absorb vitamin B12. Less absorption = less B12 your body can utilize. The National Institutes of Health recommends anyone over 50 take dietary supplements or eat fortified foods because their bodies are more likely able to absorb B12 from those sources.
Vitamin B12 is part of the water-soluble vitamin team, meaning your body removes any of the excess vitamin every time you pee. Since your body only absorbs what you need, vitamin B12 does not have an upper limit (UL) which is the maximum amount of a vitamin you can take without side effects.
Keep in mind that all of these studies suggest only supplementing vitamin B12 in the case of a documented deficiency. That means you should definitely talk with a healthcare professional before starting a vitamin B12 supplement.
People who are vitamin B12 deficient are often treated with vitamin B12 injections because they have the fewest barriers to absorption. But a small 2018 study found that taking higher dosage oral supplements (1,000 to 2,000 mcg) improves B12 levels about as effectively as injections.
Whole grains: Grains such as whole wheat, brown rice and barley still have their fiber-rich o
