If you take glucosamine to protect your joints, then have you looked in the mirror lately? Because your skin probably looks pretty amazing, too! A study in the Journal of Dermatologic Treatment showed a 34% reduction in visible wrinkles and fine lines in people who took a glucosamine supplement. And The Journal of Cosmetic Dermatology says glucosamine can also help wounds heal faster, improve skin hydration, and decrease wrinkles when taken as a supplement. So what gives it these potent skin powers? Well, glucosamine is a building block for hyaluronic acid, which hydrates the skin and plumps it up. You’ve probably seen skin serums with that ingredient. Well, these studies show that ingesting glucosamine can have the same effect, if not better! It’s good for our joints, because it lubricates them, helps them retain water, and promotes collagen, and it can have the same effect on our face. The experts say talk to your doctor about taking a supplement. The recommended dose is 1500 milligrams a day – and you’ll see a 34% reduction in lines and wrinkles within 5 weeks.
