Here’s some info based on a question that came up during a Bootcamp class about glucosamine supplementation. Glucosamine is an amino sugar found in the skeletons of shellfish and other organisms. Supplements are taken to help sustain or improve joint health and connective tissues. A lot of people with osteoarthritis have found it has helped decrease pain.
It helps with weight training because there is a lot of force on the joints as well as inflammation. Methylsulfonylmethane (MSM), glucosamine, and chondroitin combinations are very beneficial to reduce joint pain and decrease inflammation. Two new research studies indicate that the best strategy to protect the joints and improve your mobility is optimal body composition, a total body weight training program, and a blend of these supplements that includes MSM.
Remember to consult a professional for proper usage or for more information. An example of a combo supplement and quality of ingredients see here.
