Data is limited. Two studies (n=40 and 168) investigating the efficacy of elk velvet antler supplementation on rheumatoid arthritis found no effect, while a study conducted in people with osteoarthritis (n=53) reported symptomatic relief among participants. The small sample sizes may result in the trials being underpowered to detect effects.25, 28, 29
A systemic review on human interventions[25] makes note of a study conducted on patients of osteoarthritis (Edelman et al. 2000; cannot be located online) which found improvements in joint pain symptoms relative to baseline in the Velvet Antler group and not placebo, although a lack of information on blinding and randomization precludes results that can be drawn from this study.
