Howdy tonight sir johannpiber! Well if it helps any joints then it should work. One of the best quality formulas is on https://www.purityproducts.com/ plus they have all the copies of clinical trials and studies that prove the effectiveness of the product if you want to look them up.
I get the same product from Vitacost.com for half the price but I don't know if the quality is as good. But it works like a miracle for me!
