I’ve been using Iso Collagen for a few weeks now and I can already see and feel the difference! My skin looks smoother and more hydrated, my nails are growing stronger, and even my hair feels healthier and shinier. I also noticed less joint stiffness, especially in the mornings. It mixes easily with my drinks and doesn’t have a weird taste like some other collagen powders. If you’re looking to glow from the inside out and support your joints at the same time, this is it! Highly recommended!
