So glad to get Primal Collegen in my mailbox every month. My skin looked old and crepey, my hair was thinning and my knees constantly ached. When I researched these concerns, one thing that kept coming up was lack of collegen because of my age. I've been adding a big scoop to my morning coffee for about a year and I definitely notice the difference in my hair, skin and joints! Reasonably priced and less wasteful packaging than most companies out there. I have it on autoship and just like clockwork, it shows up in my mailbox - thanks primalharvest!
