Oral supplementation with specific bioactive collagen peptides improves nail growth and reduces symptoms of brittle nails.
Brittle nail syndrome is a common problem among women and refers to nails that exhibit surface roughness, raggedness, and peeling.
The goal of this study was to investigate whether daily oral supplementation with collagen peptides alleviates the symptoms of brittle nails and improves nail growth rate.
In this open-label, single-center trial, 25 participants took 2.5 g of specific bioactive collagen peptides (BCP, VERISOL® ) once daily for 24 weeks followed by a 4-week off-therapy period. Nail growth rate and the frequency of cracked and/or chipped nails as well as an evaluation of symptoms and global clinical improvement score of brittle nails were assessed by a physician during treatment and 4 weeks after discontinuation.
Bioactive collagen peptides treatment promoted an increase of 12% nail growth rate and a decrease of 42% in the frequency of broken nails. Additionally, 64% of participants achieved a global clinical improvement in brittle nails, and 88% of participants experienced an improvement 4 weeks post-treatment. The majority of participants (80%) agreed that the use of BCP improved their nails' appearance, and were completely satisfied with the performance of the treatment.
This study demonstrated that the daily ingestion of BCP increased nail growth and improved brittle nails in conjunction with a notable decrease in the frequency of broken nails.
