    Hair and nails

    I like taking this product only once per day for better skin, hair, and nails. I’ve been using it for several months. It’s easy to take and I’m seeing positive results. I have it on auto ship.

    Jury is out

    I don’t know for sure if this is what is helping me have less hair fallout, but I’m continuing to take these.

    Convenient way to take collagen

    I think this is helping because I have very little hair loss after using it for a few months. It is easy to take-just 3 per day in one dose. It is too soon to say if it is helping my skin. I will continue to take it.

    Clear skin

    I’ve been struggling with on and off cystic acne for 7 years. After beginning this, my skin is SO clear and glowing! I bought the teen version for my 13 year old, as she’s beginning to struggle with some acne also, her face is completely cleared up!

    Great for my skin and joints

    It seems to be helpful and my skin looks better, as well as better joint function.
