Velvet antler is the whole cartilaginous antler in a precalcified growth stage of the Cervidae family including the species of deer, elk, moose and caribou. Velvet antler is covered in a hairy, velvet-like "skin" known as velvet and its tines are rounded, because the antler has not calcified or finished developing. Velvet antler preparations are sold in China as part of Traditional Chinese medicine, and in the United States and some other countries as a dietary supplement.
Unfortunately, the potential problems with IGF would seem to negate any of these theoretical benefits. It has been shown that improper use of hormones such as dehydroepiandrosterone (DHEA), androstenedione, and human growth hormone may increase the risk for development of prostate cancer or promote the growth of existing prostate cancer by raising IGF-1 levels. Therefore, men who are taking supplements with IGF in it (or those that raise IGF levels) could theoretically be putting themselves at an increased risk for prostate cancer. Again, it hasn’t been rigorously studied so it’s impossible to know for sure, but if you have any risk factors for prostate cancer, it’s probably best to avoid taking this supplement.
A study conducted in rowers given 560mg Velvet Root for 10 weeks of training has failed to find improvements in rowing performance or other parameters of strength (bench press and leg press) in both sexes. 1350mg of Velvet Antler twice daily (daily dose of 2,700mg) for 10 weeks was noted to increase leg strength (assessed via leg press) more than placebo with no differences in the bench press; this study had a 44% dropout rate and conclusions that can be drawn are limited.
I am sure we will want to discover the truth and go buy he easy to read and well cited book to make your own study. She has a earned a PhD in nutrition. Written 500 articles, been on talk radio, on TV, in Time Magazine, Prevention Magazine and written up in the New York Times a couple times. Okay sure, so what did her book say? This is where it starts to get good...
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.
