Having a blood test? Tell the clinic you take a biotin supplement. These gummies supply 6 mg of biotin, around two hundred times the daily value, and high-dose biotin is known to skew several common laboratory assays. It is a testing issue rather than a health risk, and it matters. Full safety notes.

The Gelagen Beauty Journal

Four longer pieces: what each nutrient in the formula actually does, and how to judge a skin supplement honestly — including this one.

Why these exist

A skin supplement is easy to sell and harder to explain. These four articles are the explaining part: what biotin genuinely does, what vitamin A can and cannot be, what the B group is for, and how to test any of it on yourself over three months rather than taking somebody’s word for it.

Before you start

Gelagen is a dietary supplement, not a medicine, and it is not a treatment for acne, eczema, psoriasis, hair loss or any other diagnosed condition. Not for anyone under 18. If you are pregnant, may become pregnant or are breastfeeding, speak to your doctor first — this formula contains preformed vitamin A. The gummies contain cane sugar and corn syrup, and the biotin in them can interfere with blood tests. Everything we know sits on the safety page.
