More great info
I use to take the glucosamine chondroiton for many years. This is one of the supplements I ceased taking a few years ago. I quit taking it because of the shark cartledge and how it kept the process from calcium turn over like you mentioned. Now that I know it is made from chitin I am glad I did. I have noticed the clear smaller fibers remind me of what grows on the stalks of certain plants and they are abrasive too. I recently was taking fresh comfrey which the stalks are full of these fibers they remind you of cactus needles. I was making a brew of herbal plants for a skin spray. Would you know what the chemical make up of these plant needles are made from? I noticed this uncanny resemblence to some of my fibers in the past before. Do you have anything in your environment (clothing is the worst for my family) ?
