Hydrolysed collagen Verisol strengthens brittle nails
A daily dose of 2.5 g of the gelatin-protein Verisol - which you can buy in any chemists or health food shop - restores brittle nails to health. Brazilian researchers will publish an article about it soon in the Journal of Cosmetic Dermatology. The Brazilians gave Verisol to human participants, were supervised by the manufacturer of Verisol, and didn't bother with a placebo group.
Study
At the end of the supplementation period the researchers monitored the women for another four weeks.
Results
The number of times that the participants tore a nail decreased during the 24-week supplementation period from 10 times to 6 times a month. And that effect continued for four weeks after stopping supplementation.
The nails started to grow faster too - and that effect was still seen four weeks after the participants had stopped taking the supplement.
Mechanism
"Experimental trials have shown that bioactive collagen peptides may improve the synthesis of important proteins for the epidermal barrier, turnover, and moisture. Treatment of epidermal skin cells (keratinocytes) led to an up-regulation of filaggrin, loricrin, and involucrin, cornified envelope proteins which are important for a healthy epidermal skin barrier and skin moisturizing (Collagen Research Institutes data; not published)."
"Data from clinical [Skin Pharmacol Physiol. 2014;27(1):47-55.] [J Sci Food Agric. 2016 Sep;96(12):4077-81.] and animal [Biochem Biophys Res Commun. 2015 Jan 9;456(2):626-30.] [Photodermatol Photoimmunol Photomed. 2013 Aug;29(4):204-11.] trials have also demonstrated the improvement of the epidermal barrier and moisture after collagen peptides supplementation."
Ifs and buts
"With many different measurements taken at each visit, perhaps the most telling result is the high participant satisfaction. Interestingly, most participants reported they previously tried other treatments without success. Both the physician and the participants noticed a clear improvement and were satisfied with the treatment."
Conclusion
"Further research with larger samples and prolonged treatment is needed to explore the mechanism of action that leads brittle nails improvements, and larger, placebo-controlled studies are required to confirm the observed results."
