Vitamin B-complex supplements include all of the following essential B vitamins. All B vitamins play a role in converting food into energy in the body. Each vitamin also has a unique role in a person’s health:
· Vitamin B1 — thiamin — Vitamin B-1 is vital to the healthy growth and function of organs, including the brain and heart.
· Vitamin B2 — riboflavin — The body needs vitamin B-2 to break down fats and drugs.
· Vitamin B3 — niacin — The body needs niacin to maintain healthy skin, nerves, and digestion. Doctors sometimes prescribe high doses of niacin to help improve cholesterol levels.
· Vitamin B5 — pantothenic acid — Vitamin B-5 is essential for the health of the brain and nervous system.
· Vitamin B6 — pyridoxine — Vitamin B-6 helps the body make new red blood cells, which carry oxygen throughout the body. It also helps keep the immune system strong.
· Vitamin B7 — biotin — Biotin is essential for healthy hair, nails, and nerve function.
· Vitamin B9 — folic acid — The body uses folic acid — or folate, its natural form — to make DNA and genetic material. During pregnancy, folic acid may reduce the risk of certain birth defects.
· Vitamin B12 — cobalamin — The body’s nerves and blood cells require vitamin B-12. Adequate levels of B-12 also prevent pernicious anemia, which is a deficiency of this nutrient.
