As this supplement is derived from 'deer', the two most commonly used species of deer in mainland China include the Sika deer Cervus nippon Temminck and Red Deer Cervus elaphus Linnaeus; these species may be relevant. 'Farming' of deers for antlers includes raising deer and sawing off the antlers under analgesia, the annual yeild appears to be 120-150 tonnes and deer are not usually killed as antlers are capable of full regeneration.
One double-blind study published in the International Journal of Sports Nutrition and Exercise Metabolism tested whether or not deer antler velvet powder or extract had an impact on aerobic performance, endurance and “trainability of muscular strength” compared to a placebo. The subjects were adult males. They were given either a placebo, or deer antler extract or powder supplementation over a 10-week period while undergoing a strength-building routine. The men were measured for muscular strength, endurance, and VO2max before and after using deer antler. These results were determined by measuring circulating levels of testosterone, insulin-like growth factor, erythropoietin, red cell mass, plasma volume, and total blood volume.
Research in Korea, New Zealand and China has shown that deer antler velvet can stimulate the immune system. Extracts of deer antler velvet were variously shown to increase macrophage activity, stimulate the production of lymphocytes and increase the number of red and white blood cells. Each of these effects may directly complement the body’s ability to resist or fight disease and so promote and maintain health and an associated feeling of well being.
I took red mountain deer velvet and it really messed my stomach up. I now have cramps and bloating all the time plus it feels like my stomach shrank…I can’t eat like I used to. It was a big mistake to take that stuff. Do you know of any way I can get my stomach back to normal??? Can you recommend someone who knows a lot about deer velvet?? I have been suffering terribly since I took that junk…it’s been about 2 years now!!!! My stomach has never been the same since I took that poison!!
