Hey Ranis & Rajas! A lot of my friends ask me how I have such healthy nails because for 3-4 years of my adult life I had fakes on and now I am adamant user of Gels. For a while I didn't know why but the obvious answer is the fact that I drink this collagen shake every morning. Don't get me wrong collagen is one of the nastiest tasting drinks ever! But what's the saying? What doesn't taste good is probably good for you. Very true in the case of collagen. Additional benefits of collagen: hair growth, healthy skin & nails, and maintaining weight loss (one of my fave. effects). Although many health enthusiasts promote taking protein shakes ONLY while working out, collagen will keep the muscles you have "elastic" and in tact. In some rare cases you will even lose weight. It's really effing awesome! I discovered collagen through my naturalist in SF. I did this extensive weight loss program with her and during the maintenance phase of her program, I had to drink this every morning. I guess it just stuck because I am ALL about maintenance (and healthy living, of course).
