"AminoMar Marine Complex — proprietary blend with real clinical backing"
AminoMar has more published trials than most hair supplements. Small but real. More credible than typical 'marine collagen' marketing.
PubMed: Ablon G, 2015 — double-blind RCT of Viviscal in women with thinning hair -
"Clinically proven — 10 clinical trials cited"
All 10 trials are small (60–120 participants) and manufacturer-funded. No large independent RCTs exist for AminoMar.
Internal: review of published AminoMar trial literature -
"92% of women saw thicker hair"
Statistic from a 60-person manufacturer-funded trial. Examine.com notes marine collagen evidence for hair is preliminary and industry-driven.

"Biotin promotes hair growth"
Biotin only helps hair if you are deficient. The 120 mcg dose here is far below the 2,500–10,000 mcg used in hair studies.
Consumer advice
If you have confirmed nutritional deficiencies (low iron, zinc, or biotin), address those first with targeted supplements — far cheaper. If you've ruled out deficiencies and want to try a hair supplement with at least some clinical backing, Viviscal is one of the better-studied options in this category. Commit to at least 3 months before judging results. The subscription saves money but check the cancellation policy before enrolling. Not suitable if you have seafood allergies. See a dermatologist if hair loss is significant — supplements won't fix androgenetic alopecia or thyroid-related loss.
