Bests & Worsts Reviews from Amazon

My head tells me this shouldn't work and the research is inconclusive or lacking. My body says it feels better. Guess who wins? I have been taking this product for about six weeks and my osteoarthritic knee and the rest of my achy joints feel better. I also exercise and take other supplements, but adding this collagen to my routine seemes to have helped. I have not experienced any adverse side effects. I tried adding this to plain water and it really is not completely tasteless. It helps to add it to something with flavor. At first I was unwilling to risk the flavor or my morning coffee but finally tried it. This is by far the simplest way for me to take it. The powder dissolves quickly in hot liquid. I give it a quick stir with a spoon and drink. I drink my coffee black and the small amount of flavor from the collagen is completely masked. I chose the SportsResearch product because it is made in the USA and was given positive reviews. I really appreciate the people on Amazon who take time to submit comments. They didn't steer me wrong. Update 7/5/2016: This is now a product of Brazil according to the updated product images. I'm adding a photo of the product I have just to show that it is different. I have not tried the current version. I know Brazil is a big beef producer, but have not tried the new product.
