Our Honest Assessment

Ic research strong

Strong Research

Medical research clearly shows that the B vitamins play important roles in the body. They help you produce energy, create blood cells, and are important for growth. Severe deficiency in B vitamins is rare, but it can cause health issues including fatigue, irritability, nausea, among others.

The B vitamins that make up the B complex are found in a variety of foods. If your diet sometimes falls short, B-Complex can help you ensure you're getting enough of each of the B's.

Dietary sources and concerns

B vitamins are very important and many people get less than the recommended daily amount of these nutrients. Certain groups are at higher risk for depletion of B vitamins, including people adhering to a gluten-free diet, people who don’t eat enough fruits and vegetables, and people who frequently consume alcohol.

B vitamins are essential for the nervous system. They are important for several aspects of brain function: chemical signaling, energy production and synthesis of DNA and RNA all depend on these water soluble vitamins. B vitamins support homocysteine levels and are necessary for proper cellular functioning as they are a coenzyme for enzymatic reactions. B vitamins are found in many foods, but if you aren’t eating a balanced diet, you may be missing some of these eight essential vitamins. For instance, vitamin B12 can only be obtained through meat products. If you aren’t sure that you are getting enough B vitamins from your diet, supplementation may be beneficial to you.
