Biotin- What Are The Benefits & Reactions of B7?

Biotin supplements

Biotin, also known as Vitamin H or B7, is a popular supplement to attain healthy hair and nails. In fact, it is the primary ingredient in most Hair Skin and Nail formulas. Vitamin H functions as a water-soluble vitamin, which means it can be broken down in water.

Excess B7 is eliminated through urine.

Vitamin H is an essential compound for enzymes in the body to help metabolize food and create protein. Human bodies do not create Biotin.

It is attained through food consumption or created by certain bacteria in the gut. Pseudomonas denitrificans , Bacillus megaterium, and Propionibacterium freudenreichii are gut bacteria that are able to synthesize Biotin within our body.

What Biotin Is Good For?

Vitamin H is often prescribed to patients with Uncombable Hair Syndrome, increasing hair growth and making the hair easier to comb after months of taking the supplement.

Some medications, like valproic acid, affect the absorption of B7, leading to hair loss.

Taking B7 while on Valproic acid can improve alopecia along with other symptoms caused by a Biotin deficiency.

Vitamin H lowers blood glucose and helps with diabetic nerve pain.

It is involved in converting Folic acid into its active form 5-Methyltetrahydrofolate. This is necessary to create new red blood cells and prevent anemia.

A 1989 study of a 2.5 mg dosage of Biotin taken for 5 months improved the nails of 45 patients, making them less frail and thickened.

In 2015, a marine supplement containing Biotin taken for 3 months reduced hair shedding in patients.

What Causes A Biotin Deficiency?

Biotin deficiency is uncommon, although can be caused by several factors. Lacking proper nutrition and necessary gut bacteria are the starters to developing a B7 deficiency.

In some cases, there are not enough Biotinidase enzymes to reprocess B7 in the body.

Pregnant women, smokers, sufferers of liver disease, and people with intestinal damage caused by maladies such as irritable bowel syndrome, or Crohn’s disease are at risk.

Another concern is that Vitamin H may not be absorbed properly when taken with other substances, such as raw eggs, and antibiotics. Raw eggs contain a glycoprotein called avidin, which binds to Biotin, preventing absorption.

Antibiotics can destroy the microflora necessary to produce Vitamin H.
