Our Hydrolyzed Marine Collagen is produced from the skin of wild sea fish, such as silver carp, salmon, cod, etc. Marine Collagen has the most similar structure to human collagen, therefore it is best absorbed by our body. Collagen helps delay the signs of aging such as wrinkles, skin elasticity, joint problems, and weakness. It also helps in the growth of hair and nails and improves the quality of sleep.
