Try collagen gelatin. . .the kind that goes in anything. . . hot or cold. Sugar is a killer for joints also. Have you tried some Food Grade DE?
I discovered Dr. Axe (draxe.com) during a Wellness Summit put on by WellnessMama.com Worth going to both sites.
I have taken absolutely no supplements! Just walking 7 miles on the golf course during each round must have jacked up my natural production of beneficial things in my body. My heart rate is better, my blood sugar is lower, and my blood pressure is better, my hip joint pain is gone, and no more backaches! Ok..I do swallow one 10 mg Lisinopril each day.
My diet has lot of fish, shrimp, coconut oil, southern pecan pie, ground turkey meat, whole wheat Greek pita breads, Greek yogurt, sweet chili frozen chicken pieces, and McDonalds hamburgers. And of course any vegetable and fruits on sale.
