What it does: B vitamins act as essential coenzymes that help the body turn carbohydrates, fats, and proteins from food into cellular energy, support the nervous system, aid in the production of neurotransmitters, and contribute to DNA synthesis and red blood cell formation.
How it is used: B vitamin complexes and individual B vitamins are widely taken to support energy metabolism, cognitive performance, healthy mood, nervous system function, and the body’s response to physical or mental stress.
Natural sources and supplement forms: Naturally found in animal products (meat, eggs, dairy, fish), leafy greens, whole grains, legumes, seeds, and fortified foods, B vitamins are also available in supplements as standard or bioactive forms (such as methylcobalamin for B12 and methylfolate for B9).
Why it appears in supplement formulas: B vitamins are included to help address common dietary deficiencies, support energy production, and promote brain and nerve health, especially in people with increased nutrient needs or restricted diets.
What to know before use: B vitamins are generally safe at recommended intakes, but very high doses—especially of niacin or vitamin B6—can cause side effects. Speak with a healthcare provider if considering large or long-term doses, or if you have underlying health conditions.
