There is a simple thing you can do to build collagen in your body. Add collagen powder to water, orange juice, soups & smoothies. A scoop a day will not only improve your skin, hair, and nails, it can help with joint stiffness. I was using it for quite awhile and then got out of the habit. I am anxious to get started on it again. For me, it worked very well. I just ordered some today. The brand I bought is NeoCell. I have also purchased Sports Research collagen powder. www.neocell.com has recipes for adding the powder. You can put it in just about anything!
