Collagen Peptide Supplement May Improve Nail Brittleness
Brittle nail syndrome refers to nails that exhibit surface roughness, raggedness, and peeling. A recent study suggests that taking a daily collagen peptide supplement may boost fingernail growth by 12% and reduce the frequency of broken nails by 42%.
Participants in the study included 25 healthy women who were given 2.5 grams of a collagen peptide supplement or a placebo daily over the course of 24 weeks. Nail growth rate, frequency of cracked and/or chipped nails, and a clinical improvement score of brittle nails were all assessed by a physician during treatment and 4 weeks after finishing treatment.
Four weeks after the treatment period ended, 90% of the women in the supplement group reported improvement in their nails. They reported a 42% decrease in frequency of broken nails and a 12% improvement in fingernail growth. Additionally, 64% achieved a global improvement in brittle nails and 80% said they were completely satisfied with the results.
Researchers from the Brazilian Center for Studies in Dermatology led the study. It was published online ahead of print on August 8, 2017, in the Journal of Cosmetic Dermatology.
Previous studies suggest that collagen peptides may help with joint and bone health, particularly as we get older. Because collagen peptides dissolve in water, it’s best to take them in the form of a drink supplement.
