No more popping joints
I have been using this product along with BioSil Advanced Collagen Generator for about a month now. 2 capsules a day. Having worked in the food service industry for over 20years carrying and lifting heavy trays, my shoulder joints were sore and popping every time I moved my arms to do gardening or any other rotating motion. This is my 2nd bottle and I literally have "no" joint pain and the popping has stopped completely. It might seem a little pricey, but "Oh so worth it" in my opinion. These 2 are now a regular part of my day and wouldn't be without them.

keeps bones strong as you age
This is an excellent product for keeping bone density strength. Every ingredient in this product enhances bone density. I've taken this product for a couple of years and it does give good results on my bone density tests. If you have ever worried about osteoporosis, this product can help. Good quality all around.

Best Bone Medicine I've Found
I have osteoporosis and need help getting the right ingredients that I can't get from my normal diet, which is even harder being allergic to milk. I was happy to find this and hope it will positively effect my bone density. I look forward to much improvement in my health.

Don't know the effect yet.
The last medical check-up showed my bone density decreases, so I take this capsule together with calcium supplement to increase the calcium absorption. I just finished one bottle, but I only take one capsule a day, since I also take the other Biosil for hair/nail. So maybe I need to be patient to see the effect.

My bf is starting to feel relief in his shoulder finally! For 2 years he couldn't do much sport because of the shoulder trauma. Now after taking this collagenizer for a month he says his pain is muuuch less and he's even started doing sport! Very high quality, he'll continue to use it until all symptoms disappear. Oh, and maybe it's important to say -- he didn't ONLY take this product, he took it with others: Total Veggie Joint, Hyaluronic Acid, MSM.

Works well
I do feel my joints are a lot smoother and stronger with this product. However, it's too expensive, and I can't afford it anymore, but do test it out for yourself!
