Abstract

Osteoarthritis (OA) is a chronic condition that impacts quality of life and functionality for which consumers often seek dietary supplements to provide some relief. The purpose of this double-blind, placebo-controlled clinical trial was to assess the safety and efficacy of a water-soluble chicken eggshell membrane hydrosylate (WSEM) dietary supplement (BiovaFlex®) 450 mg daily on knee function, mobility, and general health and well-being in 88 adults with OA randomized into intervention (n = 44) or placebo (n = 44) groups. Outcomes were assessed periodically over 12 weeks, including the Western Ontario McMaster Osteoarthritis Index (WOMAC), the six-minute walk test (6MWT), knee range of motion (ROM) testing, and safety. Normalized analysis (improvement over baseline) showed that the poorest initial performers benefited the greatest from the WSEM by day 5 in the 6MWT, with the rest of the population showing significant improvement over placebo by week 12. The normalized WOMAC Stiffness score was also significantly improved over placebo by day 5 (P < .05). Without normalization, no statistically significant improvements were seen in WOMAC, 6MWT, and ROM testing. The Product was also found to be safe in this study. In conclusion, daily consumption of WSEM significantly enhanced average individual physical capacity (walking distance and ability), reduced stiffness by the fifth day of supplementation with the greatest benefit seen by the most compromised individuals, and was maintained over 12 weeks. A WSEM dietary supplement may offer a safe option for relief from symptoms and increased mobility for those with OA.
