Most likely many of you have seen ads or spoken to women who are drinking or selling
beverages laced with collagen. The sales pitch for these drinks is that drinking collagen will
rebuild and enhance the collagen in your skin and that Japanese women have been doing
it for years (so of course it must be valid, right? And of course women who don’t drink
collagen must look wrinkled?). I can see why this would be easy to accept. For more than
two decades women have believed that collagen added to skin-care products will add to the
collagen in your skin, so why wouldn’t the same be true from the inside out? After all, if
you drink dairy products rich in calcium you do get better bone growth.
