The Beauty of Biotin

By: Callie Pillsbury on Jan 23, 2019

Biotin is a stable B vitamin that functions in the metabolism of macronutrients such as proteins, carbohydrates, and proteins. Other names for biotin include vitamin B7, vitamin H, or coenzyme R. Biotin is a coenzyme involved in the creation of nucleic acids and fatty acids. Additionally, biotin is an important factor in the creation of fats, specifically for adequate fat production in the body. Even though biotin is responsible for the production of fat, it is not stored in the fatty tissues. In fact, biotin is a water soluble vitamin, nontoxic, and excreted from the body. Low biotin intake causes an adverse effect of fat metabolism. (1).


Hair and nails

Biotin is often promoted by beauticians to strengthen hair and nails. However, the evidence is not sufficient


Biotin works with the other B vitamins to promote skin health. Suggestions by researchers are to use biotin supplementation to treat dermatitis, a skin rash. The skin demands fatty acids for adequate moisture and protection. Thus, a biotin deficiency causes the skin to become extremely dry (2).

Blood sugar

Biotin plays a role in carbohydrate metabolism, thus some scientists automatically think that biotin based foods help stabilize blood sugar levels. It has been proposed that low biotin levels causes an impairment in the hormone insulin. However, the evidence of biotin’s role in blood sugar regulation is limited. Research is currently being conducted on the combination of biotin and chromium supplements as potential nutrients to lower blood sugar levels. To date, there is limited evidence that biotin alone can have a benefit in blood sugars (3).


The prolonged use of antibiotics can cause a low levels of biotin production. The antibiotics destroy the beneficial gut bacteria that helps produce biotin (1).


The adequate intake (AI) for adults is 30 mg per day. The requirement of biotin is minimal because the gut can actually recycle and synthesize the vitamin. Biotin is available in the food and supplement form (4).


Serving Size

μg of biotin


1 boiled

25 μg


¼ cup

15 μg

Sweet Potato

1 cup



1 cup


Whole grain bread

1 slice



1 cup


Raw Egg Whites

The consumption of raw egg whites can lead to a deficiency of biotin. This results because of a protein called avidin that is present in raw egg whites and makes the body not able to absorb biotin. This only occurs when raw egg whites are consumed. People consuming fully cooked eggs and egg whites will not develop a biotin deficiency (5).

Biotin and Spray Drying

Biotin can be spray dried to be used in a variety of food and non food related items. Dry milk products can use spray dried biotin. Spray dried biotin can also be utilized in cosmetics and topical skin products to help moisturize the skin.
