Vitamin B complex is a supplement that usually delivers eight of the B vitamins: B1 (thiamin), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate), and B12 (cobalamin). Found naturally in meat, leafy greens, dairy, beans, peas, and whole or fortified grains, B vitamins are water-soluble and play essential roles in certain bodily functions, such as helping your body make energy from the food you eat and forming red blood cells.

Health BenefitsEach of the eight vitamins in vitamin B complex supplements has its own unique set of health benefits. For instance, vitamin B1 is critical for the growth, development, and function of cells in the body. Other vitamins, such as B2, work cooperatively in the body with other B vitamins to convert food into energy. B2 converts B6 into a usable form and aids in niacin production, which is mainly obtained from food and is essential in the proper functioning of cells. Whilst vitamin B5 breaks down fats and carbohydrates for energy and helps the body use other vitamins, such as riboflavin (found in B2), B6 is involved in immune function and is required by the body to use and store protein and carbohydrates from food in the form of glycogen. B7 helps the body convert fats, carbohydrates, and proteins from the food you eat into energy. It is also needed to make fatty acids (which help to build and sustain overall health) and maintain bone and hair health. Vitamin B9 is required to help cells produce and maintain DNA (the genetic material found in all body cells), while B12 is important for protein metabolism. Keep in mind, not everyone requires vitamin B supplementation. Speak with your health care provider if you believe supplementation may benefit you. Depending on your individual needs, your provider may advise you to take a specific B vitamin supplement, such as B6 or B12, instead of a vitamin b complex supplement. Converts Food Into EnergyMost B vitamins are involved in the process of converting food into energy. Some help to metabolize carbohydrates and others aid in breaking down fat and/or protein. While this is an essential process, that's not to say taking a vitamin B complex supplement will boost your energy. Although B vitamins are essential for your body, the effect is different when they are consumed in the form of dietary supplements rather than food. A B-complex supplement may fill a specific vitamin gap or deficiency, however, it cannot provide energy in the form of calories like a food source. B vitamins involved: B1, B2, B3, B5, B6, B7, and B12 Supports Brain HealthResearch shows that B vitamins support just about every aspect of brain health. While all B vitamins promote healthy brain function, a 2016 review published in Nutrients indicates that vitamins B6, B9, and B12 in particular play a role in homocysteine metabolism, which helps reduce the risk of cognitive decline and dementia. In particular, B12 supports healthy DNA structures, which is important during fetal development and the prevention of chronic disease and cancer. Vitamin B6 supports both brain development and function, while vitamin B9 can reduce the risk of birth defects in the brain and spine, such as spina bifida. B vitamins involved: B1, B2, B3, B5, B6, B7, B9, B12 Produces Red Blood CellsSome B vitamins, particularly vitamin B12, play an essential role in the formation of red blood cells. Healthy red blood cells are needed to transport oxygen to every part of the body, and when there's a vitamin B12 deficiency, the body will struggle to produce enough red blood cells, often leading to anemia. Vitamins B2 and B9 are also needed for red blood cell production and growth. While vitamin B5 plays a role in red blood cell production, it also helps reduce the amount of cholesterol produced by the body. And vitamin B6, which is required for more than 100 different enzyme reactions in the body, aids in the formation of hemoglobin, which also allows red blood cells to carry oxygen through the blood. B vitamins involved: B2, B5, B6, B9, B12 Promotes Nervous System HealthVitamin B2 helps maintain health of the eyes, nervous system, and skin. It also aids in the conversion of food into energy and helps enzymes in the body function properly—not to mention, it makes and repairs DNA, and helps with the optimal function of the digestive and nervous systems. B vitamins involved: B1, B2, B3, B6, B12 Supports Hormone ProductionVitamins B3 and B5 are needed for the production of hormones in the adrenal glands, such as sex and stress hormones. On the other hand, vitamin B6 stimulates neurotransmitters and hormones that influence mood and regulate the body's biological clock. B vitamins involved: B3, B5, B6 May Reduce StressResearch shows that certain B vitamins may help to alleviate stress. For instance, a 2019 study published in Nutrients determined that vitamin B supplementation can benefit mood, though more research on the dietary patterns and micronutrient statuses of broader populations is needed to make an evidence-based recommendation. B vitamins involved: B1, B2, B3, B5, B6, B7, B9, B12 May Prevent MigrainesVitamin B supplementations have been found to prevent migraines in some people, such as in a 2015 report that analyzed the effects of vitamin B supplementation on individuals with migraines. The authors determined that reducing homocysteine levels with folic acid (the synthetic form of folate) and vitamins B6 and B12 may help reduce symptoms associated alongside migraine with aura— meaning a recurring headache with sensory disturbances. However, the report notes that more rigorous research is required to determine the safety and efficacy of B vitamin supplementation as a preventative measure for people with chronic migraine headaches. B vitamins involved: B2, B6, B9, B12 Possible Side EffectsAlthough vitamin B complex supplements are water-soluble and are not retained in the body for long, large doses in supplement form can cause certain side effects. There is a daily tolerable intake level (UL) for some B vitamins (which is above what most people need) but it is not established for all of the B vitamins. For example, the RDA for thiamin (vitamin B1) is 1.2 milligrams and there is no tolerable upper limit due to there being no adverse effects recorded at intakes above 50 milligram—but that doesn't mean there can't be. The tolerable upper limit for niacin (vitamin B3) is 35 milligrams, for vitamin B6 it's 100 milligrams, and vitamin B9 (folate) is 1000 micrograms. Consuming more than the UL increases your chances of side effects such as:
Before starting any supplement, you should consult with your healthcare provider. DosageAlthough consuming a varied diet is usually sufficient for getting enough B vitamins from food, some people are at an increased risk of deficiency—particularly those who are over the age of 50, take antacid medication, or have celiac disease, Crohn's disease, gastritis, or other digestive disorders. If you have had stomach or weight loss surgery, drink alcohol regularly, or follow a vegetarian or vegan diet, you may also be more prone to a deficiency. People who are pregnant or breastfeeding may need more vitamins B6, B12, and folate. The National Institutes of Health (NIH) provides the following recommended daily intakes (RDI) for each of the eight B vitamins:
Maintaining your RDI of B vitamins can help prevent deficiencies. Depending on which B vitamin(s) you are deficient in, symptoms can include one or more of the following:
What to Look ForIn the United States, dietary supplements are not held to the same rigorous testing standards as pharmaceutical drugs. This means that the quality of supplements, like vitamin B complex, may vary from one brand to the next and you can find many different brands of vitamin B supplements at drug stores, grocery stores, health food shops, and online. When shopping for B vitamins, look for brands that have been tested by an independent certification organization, such as the U.S. Pharmacopeia (USP), ConsumerLab, or NSF International. This can help to ensure quality. Vitamin B supplements should be stored in a cool, dry place and out of reach of children. Dietary Sources of B VitaminsB vitamins are found primarily in animal food sources and fortified cereals, although many vegetables, fruits, nuts, and legumes also contain a certain amount of B vitamins. Here's a look at common food sources, of which you'll notice many overlap.
A Word From VerywellTo maintain your health, you can get everything you need from eating a varied, balanced diet filled with foods naturally rich in B vitamins, such as leafy greens, nuts, beans and legumes, whole grains, lean protein, mushrooms, and eggs. There isn't solid evidence to support taking excessive amounts of B vitamins if you're not deficient in them. However, if you're struggling to consume the RDI of B vitamin from your diet, taking a vitamin B supplement may be beneficial. Deficiency in B vitamins can cause a number of symptoms, including tiredness, anemia, loss of appetite, depression, abdominal pain, muscle cramps, hair loss, and eczema. Consult your healthcare provider to find out whether a vitamin B complex supplement is right for you. Frequently Asked Questions
