"I just LOVE this product! As a collagen (powder) user, I found that it gave/triggered acid refluxes (acid indigestion). And I had a hard time trying to find the right collagen supplement that wouldn't upset my digestion. Well... I came across Health Logics' BioCell Collagen on Amazon and reviewed just about all the customer reviews - thus, it had me on the ordering page LOL. In just a week, taking two in the mornings on empty stomach, and/or taking 1 supplement before breakfast, 1 before lunch, have found the supplement does NOT hurt me - wow! AND, I no longer get up in the mornings with that nagging stiffness in my back (no more 'popping' in my bones as I move anymore!) I'm doing things about the yard and house that I haven't done in a long time - yes, this stuff (BioCell) is also giving me 'energy'... this in a week's time, imagine what'll it do for me in another few months? LOL At my age (62 in Feb - ouch!), I've been concerned of osteoporosis (as many women should be!) is why I take collagen (along w/ calcium/magnesium and stem/cell supplements), have found that collagen is good for MANY things for a body. My husband, not only uses BioCell, too, but compliments his wife (me!) on her skin (because of collagen use! :) We're VERY pleased with this product, and will continue using it."
