Dr. Low Dog also reports that a chronic wasting disease in deer, elk and moose is the only recognized prion (infectious protein) disease of wild animals and has been found in 15 states and two provinces in Canada. (Prion diseases in wild animals are similar to bovine spongiform encephalopathy, better known as mad cow disease, in cattle.) No known cases of neurological disease have been seen in humans who have taken deer antler velvet supplements, but a 2009 study sponsored by the National Institutes of Neurological Diseases and Stroke and the U.S. Department of Agriculture concluded that the possibility remains.
A systemic review on human interventions 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.
Deer antler velvet's effects on cell growth and repair have been investigated in several areas. Deer antler velvet may be a natural source of hormones for those seeking aid to muscle growth and development. Research has identified various growth factors in deer antler velvet including IGF-1 (insulin–like Growth Factor-1), IGF-2 (insulin–like Growth Factor-2), and EGF (Epidermal Growth Factor).
L-Arginine: An amino acid usually found in red meats that is important for the body’s ability to manufacture proteins. L-Arginine has been used to treat conditions like high blood pressure, congestive heart failure, blocked arteries, and erectile dysfunction. L-Arginine is safe for most people, however it should not be taken by women that are pregnant or breastfeeding.
