As we age, our bodies become less effective at absorbing nutrients, which has important implications for the aging process. If you’re in your thirties or forties, it’s a good time to start thinking about a joint supplement, especially as most offer preventative benefits so that you don’t develop joint disorders down the line. Glucosamine occurs naturally in our bodies, but the levels decrease as we get older unless supplementing with Glucosamine (or eating a Glucosamine-rich diet). As you head towards 35, you may start noticing the occasional ache or twinge, which may mean that you need to boost your body’s natural levels of Glucosamine so that you can keep your cartilage healthy.
