Stronger Nails
Collagen may also benefit brittle nails and could help them grow faster. Brittle nails syndrome is common among women, with symptoms including peeling, roughness, and raggedness. One study investigated the impact of collagen supplements and whether they could significantly reduce the symptoms and promote faster nail growth. The research involved 25 participants who took specific bioactive collagen peptides (2.5 grams) every day for 24 weeks. A follow-up observation was also conducted, wherein the participants went off therapy for four weeks.
The result showed that bioactive collagen peptides had increased the rate of nail growth by 12 percent, and the frequency of having broken nails was reduced by 42 percent. In addition, 66 percent of the participants improved their brittle nails, and 88 percent experienced further improvement during the 4-week off-therapy period. Eight percent of the women were satisfied with the result and agreed that bioactive collagen peptides greatly impacted their nails.
