I got my first collagen Healthy Bones from Amazon. Then I visited the Healthy Bones Co website and found that their collagen there contains 3 extra ingredients. So I now get it from the website. I think it is superior to the one on Amazon and more expensive. I have not joined the Healthy Bones personalized program but did chat via the site with someone about my choices. They were helpful. Ultimately I chose what I thought best. I like that they don’t source ingredients from China, just a few from Germany which has high standards on ingredients. All supplements are a gamble but these work for me.
