What is vitamin B?

Vitamin B refers to not just one, but eight different B vitamins. And, not surprisingly, it doesn't have just one health benefit. In fact, vitamin B helps support a variety of functions in your body including immune function and brain health. Vitamin B also has a reputation as an "energy vitamin" because it helps enzymes release cellular energy from proteins, carbohydrates and fats from the foods you eat.

Vitamin B is naturally found in food, but cooking can remove some of its benefits—so, too, can drinking alcohol. Additionally, overly processed foods like white flour, white bread and white rice also strip B vitamins of their nutritional value.

Besides incorporating high-quality vitamin B supplements into your wellness routine, it is important to eat a diet rich in vitamin B foods, such as whole grains, legumes, citrus fruits, avocados, poultry and fish.

What is a vitamin B complex?

A vitamin B complex supplement includes all eight of the essential B vitamins in one convenient tablet. These "multi" B vitamins include thiamine, riboflavin, niacin, pantothenic acid, pyridoxine, biotin, folic acid and cobalamin.

Each B vitamin plays a specialized role in keeping your body healthy. For example, biotin, found in vitamin B7, is essential for healthy hair, skin and nails, while vitamin B5, pantothenic acid, helps keep your brain and nervous system healthy.

How to take vitamin B

Everyone can benefit from a vitamin B complex supplement, but for those who are pregnant, vegetarian or vegan, getting enough vitamin B is especially crucial.

B vitamins help support women during pregnancy by providing them with the recommended amount of folic acid needed to help support their baby's developing brain and spinal cord–and to maintain their own health.

Those who follow a vegan or vegetarian may not be getting the proper amount of vitamin B12 each day, which most people get from animal sources such as meat, eggs and dairy products. Supplementing with a high-quality B complex supplement helps protect and support brain function as well as promote healthy dopamine levels.

It is always important to speak with your doctor first before incorporating any new supplements into your wellness routine and take a lab test to see if you are deficient in any B vitamins so you can supplement accordingly.
