I deal with advancing OA along with FM and just plain messy joints, all worse in the last 5 some yrs.... I've taken many types of collagen supps and never with noticeable relief and joint support. A friend put me on to Great Lakes Gelatin (green cannister) and I'm on it now for about 1 month, I've read tons of reviews on it, talked to the company that produces it and convinced it's HELPING me.... I'm still STIFF and mostly in the morning after in bed all night. and I do sleep pretty good all night... I've been seeing my rheumy for a couple yrs for acupuncture and recently more Prolo injections.....this product, and I'm HOPING big time, may keep me out of her office for I hope a while.... I started with 1T two times per day, morning and before bed...and now take up to 4T per day, some days more....the company said some take up to 9T per day.... This product does not clump, melts right into any hot or cold liquid, some even add it their foods.... Just reading more this morning on the cannister: Hydrolyzed collagen is the same collagen found naturaly in bones, skin, and cartlidge..It is a bioactive prodouct containing 90% protein easily assimilated by the human body. It promotes rapid cell growth producing synovial fluids to first lubricate joints, then build tissue...... Over the last 8 yrs or so I went thru 2 sessions of the synovial injections with no help, just a lot of money to big pharma..... This product makes so much sense and is doing a good job on my joints, SO FAR. I've come upon a blog run by an MD out of Mass and most on the blog rave about the great lakes gelatin...I may post the link.
