Vitamin B6

Vitamin B6 is a type of B vitamin. Pyridoxine, pyridoxal, and pyridoxamine are all forms of vitamin B6. It's found in certain foods and also made in a lab.

Vitamin B6 is needed for the proper function of sugars, fats, and proteins in the body. It's also necessary for the development of the brain, nerves, skin, and many other parts of the body. It's found in cereals, legumes, and eggs, and often used with other B vitamins in vitamin B complex products.

People commonly use vitamin B6 for preventing and treating vitamin B6 deficiency. It is also used for heart disease, premenstrual syndrome (PMS), depression, morning sickness, Alzheimer disease, menstrual cramps, diabetes, and many other conditions, but there is no good scientific evidence to support many of these other uses.

When taken by mouth: Vitamin B6 is likely safe when used appropriately. Taking vitamin B6 in doses of 100 mg daily or less is generally considered to be safe. Vitamin B6 is possibly safe when taken in doses of 101-200 mg daily. In some people, vitamin B6 might cause nausea, stomach pain, loss of appetite, headache, and other side effects. Vitamin B6 is possibly unsafe when taken in doses of 500 mg or more daily. High doses of vitamin B6, especially 1000 mg or more daily, might cause brain and nerve problems.

Special Precautions & Warnings:

Vitamin B6 is an important nutrient. Cereal grains, legumes, vegetables, meat, and eggs are good sources of vitamin B6. The amount that should be consumed on a daily basis is called the recommended dietary allowance (RDA). For males, the RDA is 1.3 mg daily for those 19-50 years old, and 1.7 mg daily for those over 50 years. For females, the RDA is 1.3 mg daily for those 19-50 years old, and 1.5 mg daily for those over 50 years. While pregnant, the RDA is 1.9 mg daily. While breast-feeding, the RDA is 2 mg daily. In children, the RDA depends on age.

In supplements, vitamin B6 is often used alone and in products containing other B vitamins. Speak with a healthcare provider to find out what type of product and dose might be best for a specific condition.
