Nutrigenomics: Vitamin B7

Posted by Athletigen on Thu, Jan 10, 2019

Vitamin B7 (biotin) is a water-soluble nutrient found in various foods and is made by some of the bacteria found in your digestive system. Biotin helps regulate how efficiently your body uses energy from non-sugar sources and the energy stored in fats.

It also helps during the metabolism of branched-chain amino acids (BCAAs). Biotin may also help your body regulate blood sugar levels and gene expression.

Biotin deficiencies can cause or accelerate various irritated skin conditions, hair loss, and the buildup of fats in the liver. You can obtain biotin from many dietary sources including pork, beef organ meats, egg yolks, and dairy products. Vegan and vegetarian sources include whole grains, mushrooms, legumes, avocados, nuts, and chocolate.

Many environmental factors can put you at risk of biotin deficiencies, such as over consumption of alcohol or long-term antibiotic use. But your genetics also come into play.

The BTD gene has a key role in the regulation of biotin absorption and metabolism. Certain variants of this gene are associated with deficiencies of biotin synthesis and metabolism, resulting in decreased biotin levels.
