What is in Viviscal and how does it work?

Viviscal is a marine-based supplement containing AminoMar, a proprietary blend of shark cartilage and mollusk powder, along with biotin, zinc, vitamin C, iron, and horsetail extract. Multiple clinical trials have shown that Viviscal may support hair growth and reduce shedding after 3 to 6 months of use. It is one of the more extensively studied branded hair supplements.

How long does Viviscal take to show results for hair growth?

Viviscal clinical trials have assessed outcomes at 90 and 180 days (3 and 6 months). Research across 9 studies with 100 participants for both telogen effluvium and age-related hair thinning shows Grade A (Strong) evidence with statistically significant improvements at the 6-month mark. Many trial participants reported visible reductions in hair shedding at the earlier 3-month assessment. Consistent daily use throughout this period is required.

What is the AminoMar marine complex in Viviscal?

AminoMar is Viviscal's proprietary marine protein complex derived from fish cartilage and other marine sources, providing shark and mollusk powder along with biotin, vitamin C, zinc, and iron. The marine proteins supply amino acids thought to nourish hair follicles during the anagen growth phase. Research across 9 studies with 100 participants supports Grade A (Strong) evidence for this formulation in hair outcomes, though studies were largely conducted or sponsored by the manufacturer.

Is Viviscal safe for long-term use?

Viviscal has been used in clinical studies for up to 6 months without significant safety concerns reported. The formula contains shellfish-derived ingredients, making it unsuitable for people with seafood allergies. Iron content in Viviscal may be a concern for people with hemochromatosis or iron overload conditions. No long-term safety data beyond 6 months is available from the 9 studies reviewed. Consulting a healthcare provider is advisable for prolonged use.

Does Viviscal work for men with hair loss?

Viviscal's published clinical research includes both men and women with hair thinning and telogen effluvium. Research across 9 studies with 100 participants supports Grade A (Strong) evidence that the formulation may help promote hair growth in adults experiencing diffuse thinning. The evidence base is smaller than for established treatments like minoxidil, and most studies were industry-funded, which may affect result interpretation. It does not address the DHT mechanism central to androgenetic alopecia in men.
