Great supplement for hair.
Tablets are small and easy to swallow. Quantity for the price is excellent. Derms say Bioting dont work but as soon as I stop using this product my hair thins out and I start losing a lot of hair. Wont hurt my stomach if I take it without food. No taste whatsoever.

Better than sugar filled, corn syrup gummies
I like these because they’re small and easy to swallow. I bite them in half and use half a pill a day because that’s really all you need. They don’t have any taste. It’s a better alternative than the biotin gummies that are loaded with sugar and corn syrup. And I can honestly say that after maybe 10 years to a year of being on biotin I noticed that my hair definitely thickened up and became easier to style. My thin areas are smaller and easier to hide now. BUT I’ve also been taking finasteride (propecia), as well as using minoxidil twice daily and ketaconozole 2% shampoo 3x/week. So I’m sure they’ve all worked together. I hope this helps anyone else out there who’s looking to thicken their hair!
