Fish collagen is a Type I collagen extracted from fish skin and scales. Its small peptide size and high bioavailability may allow for better absorption than bovine or porcine collagen.
People take it to promote skin elasticity, hydration, and joint comfort. You can mix the powder into water, coffee, or smoothies, or take it in capsule form.
Those who avoid bovine or prefer a marine source often turn to fish collagen. Not suitable if you have a fish allergy. Speak with a healthcare professional if pregnant or nursing.
