TYPE I COLLAGEN

Sproos Marine Collagen

Why I Like This Product

• Single-ingredient formula
• Hydrolyzed collagen peptides
• No added sweeteners, fillers, or unnecessary additives
• Non-GMO, wild-caught, and sustainably sourced
• Third-party tested for purity and contaminants

Potential Shortcomings

• The available evidence suggests that doses as low as 5 g daily can provide skin health benefits. While a 10 g serving is within the range used in clinical studies, higher doses have not been consistently shown to provide greater skin benefits.
• Many collagen products promote benefits for hair growth and nail health. While collagen provides amino acids that contribute to the structure of hair and nails, the current evidence supporting meaningful improvements in hair growth or nail strength is limited compared with the stronger evidence for skin health.
