I never heard of collagen peptides. I will have to look into that. One thing I found out recently was that anti-seizure medicines, like Lyrica, which I was on for peripheral neuropathy, and statins, which I’ve been on for 20+ years for high cholesterol, are very hard on bones and can cause osteoporosis. I went to see a holistic chiropractor, and with his help I have been off Lyrica for seven months and my PN symptoms have not returned.
