Biotin, also known as vitamin B7, is a water soluble vitamin that helps create energy in the body. It breaks down the protein in the food we eat and turns it into different amino acids; some of which form keratin.

Keratin is the main building block of hair, meaning that biotin is a necessary co-factor for hair to form — but it’s not a one-stop shop.

Biotin has been a go-to supplement for beauty since it was discovered to help strengthen brittle nails and hair.

However, the research on exactly how and why biotin is so good for our beauty is insufficient.

Mainly, it has been proven to have benefits for our hair, skin, and nails through observations and single studies, rather than repeated, double-blind clinical trials.

But as long as the effects are visible and not harmful, people will continue to buy biotin supplements.

Unfortunately, most of these supplements include unwanted sugar and food additives and have biotin in excessive doses.

I’m sure your wondering ” Can I overdose on biotin” ?

If you suffer from kidney disease, are a smoker, or have had stomach surgery, it’s important to consult with your physician before using biotin.

That precaution naturally applies for women who are pregnant or breastfeeding, or anyone taking medications.

Additionally, taking excessive biotin (dosages 10-30mg) from supplements can cause some, but not all, lab test results to be either falsely increased or decreased, leading healthcare practitioners to misdiagnose and mistreat their patients.

Follow your physician’s recommendations when discontinuing biotin to ensure test result accuracy.
