Kalman DS, et al. - In this randomized, double-blind placebo-controlled study with 88 individuals randomized evenly to Study Product (BiovaBio 450 mg/d, n = 44) or Placebo (n = 44) for 12-weeks, experts intend to objectively and subjectively assess the impacts of a nutritional intervention as contrasted with placebo on the appearances of hair, skin, and nails in healthy middle-aged adults. Oral hydrolyzed eggshell membrane ingestion was correlated with a notable improvement in facial skin appearance in crow's feet in 4 weeks and skin tone in 8 weeks, with an important impact on hair thickness, reduction in hair breakage and improvement in hair growth at 4, 8, and 12 weeks. It was found that oral supplementation of 450 mg/d hydrolyzed eggshell membrane for 12 weeks was correlated with improvement in the appearance of facial skin and hair.
