Evidence score

Emerging evidence

Early evidence, mostly unproven in humans

  • Regulatory standing. Sold as a supplement, not an approved drug
  • Limited human data. Some human data exists, not conclusive
  • Registered human trials. 2 registered studies on ClinicalTrials.gov

Computed with the same four public criteria as every profile. The human-evidence grade on an indexed profile is set automatically and may change when it is hand-reviewed. It is not a safety score, not a purity rating, and not medical advice, and not a claim that this compound treats, cures, or prevents any condition.

What it is

Marine collagen peptides are small protein fragments made by breaking down collagen from fish skin, scales, or bones. They are sold as a dietary supplement and are thought to be absorbed as short peptides and amino acids that may serve as building blocks or signals for the body's own collagen production in skin, joints, and connective tissue.

What the evidence shows

Automatic summaryLimited human data

There are only 2 registered human trials and about 34 published papers, and the existing human studies are small and short, so benefits for skin, joints, or other tissues are not established. It is not FDA approved for any use and is regulated as a supplement.
