Three weeks in and I've noticed my hair feels noticeably thicker when I pull it back, plus the 2,500 mcg dosage is easy to swallow. I take it with breakfast and haven't had any stomach upset, which was my main worry.

My nails have been peeling for years and I was skeptical, but the 2,500 mcg dose is easy to take daily and I've actually noticed a difference in their strength within a month. The capsules are small enough that I don't dread swallowing them.

Three weeks in and my hair is noticeably less brittle when I brush it through, which is a win in my book. I take one 2,500 mcg tablet with breakfast and haven't had any stomach issues, so that's a solid plus for a daily supplement.
