The biggest number on the Gelagen label is biotin. Seeing 16,667% can be startling, so here is the plain explanation.
Gelagen provides 5000 mcg of biotin per two-gummy serving. The daily value is 30 mcg, so that is 16,667% DV — a typical amount for hair and nail formulas. No upper limit has been set for biotin, but high doses can interfere with some blood tests, so tell your doctor you take it before any lab work.
What Biotin Does In Gelagen
Biotin, also called vitamin B7, helps enzymes turn food into energy and is involved in making keratin — the protein your hair and nails are built from. That is why nearly every hair, skin and nail gummy features it.
Why Gelagen Uses 5000 mcg
The daily value of 30 mcg covers basic needs. Hair and nail products commonly use 2500–10,000 mcg, and Gelagen sits at 5000 mcg. Biotin is water-soluble and the NIH notes no upper limit has been established, because no adverse effects have been clearly linked to high intakes.

Check AvailabilityThe Gelagen Lab Test Note
High-dose biotin can interfere with certain laboratory tests, including some thyroid and heart tests, and give falsely high or low results. The fix is simple: tell your doctor and the lab that you take Gelagen before any blood test. They may ask you to pause it for a few days.
Getting The Most From Gelagen's Biotin
Biotin works best as part of a balanced routine with enough protein, iron and overall nutrition. Take two gummies a day, consistently, and give it two to three months — see our results timeline.
