Retired early nearly 4 years ago partially due to arthritic pain in my right knee and hip and also my back. Exercise, weight loss (80LBS) and twice a day stretching helped only minimally. Tried various pain killers with little success. About 4.5 months ago I started taking Glucosamine with Chondroitin and MSM. After 3 months of the Glucosamine my discomfort had been reduced by more than 50%. This in itself was fantastic! About 6 weeks ago I added BioAstin Hawaiian Astaxanthin 12mg to my daily regimen. Again, WOW! The Pain in my hip and knee are but a distant memory. The pain in my back has lessened by at least 80%. What can I say - life is good again!
