Deer velvet might have an effect due to the hormones it may contain, including testosterone, androstenedione, and dehydroepiandrosterone. Research in rats, using elk velvet antler, suggested the substance may have an androgen-like effect. The antlers are ground into powder, which people take by mouth. Dosage varies by brand, but a recent study used 215 mg per day. Some distributers, though, recommend dosages ranging from 250 mg to as high as 3000 mg (3 g) per day. So talk with your doctor before you start using deer velvet.
This fancy concept is easily understood in the gym as increasing the contractile capacity of muscular groups. In other words, its strengthening to your body. Scientifically these concepts translate into increased anaerobic workloads and more weight for more repetitions, which is a progressive measuring standard of performance. Its about you reaching your goals. More progress for you equals more gains.
However, calcium and phosphorus levels (which are important for bone growth) did not differ among groups. Overall, the researchers concluded that “our results seem to support a role for dietary supplementation of EVA on growth and bone development in this model.” (9) However, it’s important to point out that this is a very high dose. It’s significantly above what most would take in supplement form.
I know of no scientific evidence to support any of the marketing claims made for these supplements. I discussed your question with Tieraona Low Dog, M.D., an internationally recognized expert in the fields of integrative medicine, dietary supplements and women’s health, and an authority on botanical medicine. She explains that IGF-1 in the velvet promotes rapid growth of the antler. Dr. Low Dog notes that the two studies examining the effects of deer antler velvet supplements taken by athletes have yielded conflicting results. One showed some improvements in endurance and knee strength in weightlifters, but the other found no differences in rowers after 10 weeks of supplementation.
Currently, one study that induced a fracture unto a rat bone and injected 20mg/kg of Velvet Antler polypeptides into the area every other day for 7 weeks noted that fracture healing rate was dose-dependently increased at weeks 4-7 relative to control and that the bone loading weight was increased following rehabilitation with 10mg/kg (60.7%) and 20mg/kg (93% more than control) after 7 weeks. An in vitro study suggested that this was due to a concentration-dependent mitogenic activity on osteoblastic precursors and chondrocytes.
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).
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.
Deer Antler Velvet Spray is an extract that’s taken directly from the material that grows on the outside of the antlers of deer, elk, moose and caribou. Their website suggests its use for anyone that is looking to counter the effects of light exercise, mild muscular strain and exertion, and some arthritic conditions. In addition to providing joint support, Deer Antler Velvet Spray is said to balance hormone levels, build muscle, boost sexual performance, and improve immune function.
In rats undergoing left coronary artery ligation, those with heart failure were given either Velvet Antler (Deer) or Captopril as active control for 4 weeks with a third group given water. No significant changes in cardiac structure was noted with either Velvet Antlers or Captopril (with the heart tissue being enlarged after heart failure) although left ventricular ejection fraction (LVEF) and fractional shortening (LVFS) appeared to be improved in both treatment groups to approximately the same degree and the increase in serum Brain Natiuretic Peptide (BNP) that occurred with heart failure was attenuated the same degree in both interventions.
