The product smells like lemon-scented cleaner and bears a resemblance to murky pond water. I hesitantly tried the stuff and found it surprisingly palatable, with a lemon taste, but not too sour and slightly sweet. The directions say to take 14 drops under the tongue, three times a day, but I stopped after one dose — so I probably don't have a good chance of reaping the benefits, if there are any.
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.
