Potential Health Benefits

Biotin is a B complex vitamin. It’s involved in the process of turning food into energy for the body.

In addition to biotin being an important component in many processes that happen in the body, biotin has several health benefits.

The main benefits that biotin is associated with are improving the health/appearance of the hair, skin, and nails. Biotin may be beneficial for the hair, skin, and nails, but scientific knowledge of this topic is not definitive.

Interest in biotin as a supplement for hair likely came about because biotin deficiency is associated with hair loss. (1) (2) However, this fact doesn’t mean that just anyone’s hair health will benefit from taking a biotin supplement—people with an actual biotin deficiency will benefit the most from biotin supplementation. (3)

More research is needed on the topic of biotin to determine if it’s beneficial for healthy individuals’ hair.

Like with the hair, if you’re deficient in biotin, it can have adverse effects on the skin, such as developing rashes. (4) (5)

There have been some studies that indicated biotin provided relief from skin conditions, but the available studies were done in infants with alopecia. (6) (7) More study is needed on the topic.

There have been some studies on biotin’s effects on the nails as well, but evidence is limited and the studies didn’t include placebo groups.

In one, nail thickness increased by 25% after biotin supplementation. (8) In another study, 91% of participants who were able to be evaluated “showed definite improvement with firmer and harder fingernails”. (9) In the last study, 35 participants were prescribed a “B-complex vitamin biotin” and were evaluated over a 6 month period. 63% showed clinical improvement. The rest saw no change in their nails. (10)

As you can see with these studies on biotin’s relationship to the hair, skin, and nails, there have been some promising results. These results need to be put into context though: they were small studies, not the highest quality, and what we do know is that biotin may only be of benefit to people with a biotin deficiency.

There are other potential health benefits from supplementing with biotin.

Biotin fuels the enzymes that are responsible for the metabolism of fat, protein, and carbohydrates.

It’s also important during pregnancy and breastfeeding. During pregnancy, more biotin is required, so it’s a good idea to take a supplement like this or take a prenatal vitamin containing biotin.

Some animal studies appear to show a link between biotin deficiency and birth defects. (11) (12) (13)

Dosage & When to Take It

A serving size of this supplement is one vegetable capsule. We recommend taking it with a meal and beverage, but it is easier on the stomach since it’s made with a vegetable capsule.
