Natural Marine Collagen improves the quality of weak, brittle and damaged nails by making them stronger and shinier from the inside out (it’s clinically proven). Vida Glow’s marine collagen has undergone a special hydrolysation process. This allows for peak absorption of the amino acids and peptides your body needs to produce collagen – the protein responsible for giving your skin, hair, nails and joints their structure, strength and shine. Simply put, collagen is the supplement that knows exactly what your nails need.
