The company has found that powders have only about a 15–20 percent absorption rate of IGF-1. This is due to how the digestive system breaks down the powder. Nutronics states that their “proprietary sublingual spray delivery system” is superior to many competitors because it offers “enhanced bioavailability” of IGF-1. They also point out that “it is not the milligrams of Deer Antler Velvet in the product, it’s the content of IGF-1 and other Growth Factors in Deer Antler Velvet, that makes the difference.”(6)

Chondroitin sulfate is a compound of connective tissues that are usually found in cartilage. Glucosamine sulfate is a natural building block for the growth and maintenance of healthy cartilage. Since osteoarthritis is caused by the deterioration of the cartilage in the bone joints, a daily supplement of deer antler velvet can help to stimulate the repair of deteriorated bone cartilage with healthy doses of chondroitin sulfate and glucosamine sulfate.


Deer antler velvet can play a pivotal role in helping to not only relieve the symptoms of diseases that affect joints, such as osteoarthritis, they can possibly eliminate them entirely. The way it may do this is through the introduction of chondroitin sulfate and glucosamine sulfate into the body. Both of these compounds are abundant in deer antler velvet.
