Vital Proteins Collagen Peptides

Cons

• Evidence for many of the highly promoted benefits, especially for hair and nail growth, is not as strong as claimed and often comes from studies funded by supplement manufacturers.
• Collagen is not a 'complete' protein because it lacks tryptophan, an essential amino acid, meaning it shouldn't be your sole protein source.
• Can be an expensive way to get protein compared to other dietary sources like lean meats, dairy, or plant-based proteins.
• Not suitable for vegetarians or vegans, as it is derived from animal sources (typically bovine or marine).
• Some individuals may experience mild digestive issues like bloating or stomach upset.
