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.
Osteoarthritis is caused by the loss of cartilage in bone joints. In normal joints, cartilage serves as a buffer between bones. Usually the body replenishes cartilage as it wears away, but when osteoarthritis occurs, cartilage deteriorates faster than the body can replace it. Eventually, the bones begin to rub together, causing pain, swelling and loss of joint mobility. Most treatments for osteoarthritis attempt to reduce pain and maintain joint function, but these treatments do little to restore joint health.
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.
