I love it, all of them together!
I get my favorite ingredients in one product- saves me $$$ and only need one product. I have truly enjoyed collagen from this company. Very clean, tasteless but most importantly the collagen has done wonders for my skin. Worth every penny - package is shipped properly and delivered to my mailbox unlike Amazon which has been a nightmare lately.
I noticed a difference in my hair growth and shine. My nails seem stronger.
