Vitamin B supplements -

B vitamins can be found in many foods. Here are the best sources of B vitamins:. There are many other foods that contain different amounts of B vitamins.

People who follow restricted diets, like vegan diets , are more likely to be low or deficient in B vitamins, such as B12, and might require a B-complex supplement in order to meet their needs. People who are unable to meet their B vitamin needs through diet alone may require a B vitamin supplement.

This might include people whose diets are low in B vitamin-rich foods, people who are on B vitamin-depleting medications, and people who have medical conditions that interfere with the absorption of B vitamins.

While some people may only require supplementation with one B vitamin, such as vitamin B12 , others may benefit from taking a B-complex supplement that provides all eight B vitamins. To select our top supplement picks, our team of registered dietitians thoroughly research and review supplements and interview experts.

We evaluate products on several criteria, including safety, efficacy, dosage, quality of ingredients, and testing certifications, to help you determine the best supplement for your individual needs.

Read our complete guide to B12 supplements here , but this is our top pick. If you develop low or deficient levels of one or more B vitamins , you may experience certain symptoms and health issues. If a B vitamin deficiency becomes severe, it can significantly harm health and may even be fatal.

Because of this, B vitamin supplements are safe and are not associated with many adverse health effects, even when consumed in very large doses. However, because B12 has such a low level of toxicity, high-dose B12 supplements are generally safe for consumption.

However, consuming excessive quantities of certain B vitamins when it's not necessary could harm health. Very high doses of supplemental B3 niacin may lead to skin flushing, vomiting, high blood sugar levels, low blood pressure , and potentially liver damage.

They can help you determine whether a B vitamin supplement may be beneficial for your health and can recommend appropriate dosing.

B vitamins refer to eight nutrients that play important roles in health, such as supporting cellular function, metabolism, energy production, red blood cell development, and neurotransmitter production. B vitamins are found in a number of foods, including both plant and animal foods.

Most people following well-rounded diets are able to meet their needs through food alone. However, B vitamin supplements may be necessary for certain populations, such as people with medical conditions that interfere with B vitamin absorption, pregnant and breastfeeding women , and people following restrictive diets.

J Clin Biochem Nutr. The National Institutes of Health estimate that about 6 percent of adults younger than 60 in the United States and United Kingdom have a vitamin B12 deficiency , but that number jumps to about 20 percent in those older than People of low socioeconomic status, women, and non-Hispanic Black individuals are also likely to have low vitamin B12 intakes.

To get more B12 in their diets, individuals may turn to vitamin-rich natural sources, such as dairy products, fish, meat, and — in particular — beef liver and clams.

This type of vitamin B can also be found in fortified items like breakfast cereals and nutritional yeast. Vitamin B1 plays a major role in metabolizing food into energy. B1 is found in whole-grain cereals, yeast, beans, nuts, and meats.

As MedlinePlus notes, too little vitamin B1 causes beriberi, a disease affecting the heart, digestive system, and the nervous system.

Beriberi is found in people who are malnourished, as well as in those who are heavy alcohol drinkers. Symptoms of beriberi include difficulty walking, loss of sensation in the hands and feet, and paralysis of the lower legs — and it may even lead to congestive heart failure.

Taking any one of the B vitamins for a long period of time can result in an imbalance of other important B vitamins, so a B-complex vitamin, which includes all the B vitamins, may be the best option.

When starting any vitamin regimen, however, be sure to consult with your doctor. Vitamin B2, also known as riboflavin , produces powerful antioxidant activity so the immune system can function properly, according to a study published in in the International Journal of Molecular Science.

Lab analysis published in in the Journal of Physiology and Pharmacology of macrophages cells that play a significant part in immunity suggests that riboflavin deficiency impairs proper immune response, while riboflavin enrichment decreases inflammation.

She notes, however, that much more research is needed to fully understand the impact of vitamin B2 on immune function. Beyond boosting the immune system, getting enough riboflavin may help prevent migraine headaches and cataracts , according to MedlinePlus.

In research published in in the International Journal for Vitamin and Nutrition Research, researchers looked at seven previous studies and found that taking B2 supplements in adults may help reduce the frequency and duration of migraine attacks with no serious side effects.

The National Institute of Neurological Disorders and Stroke lists riboflavin as a possible natural treatment for migraine. Riboflavin may also increase energy levels, boost the immune system, and treat acne, muscle cramps, and carpal tunnel syndrome. Not getting enough niacin in your diet causes a disorder known as pellagra.

As the Cleveland Clinic describes it, pellagra is a systemic disease, affecting the body as a whole because cells are deprived of the energy they need to perform bodily functions.

This will eventually affect the brain and nervous system. Symptoms of pellagra include both physical and mental difficulties, diarrhea, inflamed mucus membranes, and dementia.

Pellagra can also result when the body is not able to absorb enough niacin because of alcoholism. Health benefits of niacin include its use as a treatment to help control high cholesterol.

Deficiency in B12 is also damaging to the nervous system and has been linked to dementia, as well as depression and confusion. Research in the journal Cureus in indicated that low B12 may impair cognition and memory and bring about a sensation of tingling and numbness because of poor myelination the insulating layer, or sheath that forms around nerves.

The investigation included adults who had mild cognitive impairment. About 8 in 10 had marked improvement after receiving vitamin B supplements. This type of B vitamin is needed for the production of sex and stress-related hormones produced in the adrenal glands, small glands that sit atop the kidneys.

It's also needed for growth. You can find vitamin B5 in vegetables such as broccoli, kale , and avocado, as well as whole-grain cereals , potatoes, dairy, and organ meats. For babies, folic acid can also help prevent major birth defects of the brain anencephaly and spine spina bifida , says the Centers for Disease Control and Prevention.

While the National Institutes of Health recommend that teens and adults get micrograms mcg daily, breastfeeding mothers should get mcg a day, and pregnant teens and women should get mcg a day. What vitamins are usually considered members of B-complex vitamins?
