Began taking Dr. H about 6 years ago per a recommendation from my Lyme Doctor. Dr. H. has virtually eliminated any joint pain. I am in my 70's and had extensive back surgery in 2019. But, I still play and walk golf course 3-4 times per week (about 30-35 miles) with no joint discomfort! Have recommended to other golfers and have heard all provide positive results from taking Dr. H. Thanks....could not be more satisfied!
