What is Giant kelp peptide?
It is a peptide-containing fraction derived from Macrocystis pyrifera (giant kelp). The ingredient-list identity is the exact fraction named on the label, not the source organism in every form.
What evidence does MIRU hold for Giant kelp peptide?
MIRU has not found a human topical study matching this exact peptide fraction. Findings from giant-kelp extracts or other kelp materials or from named synthetic peptides cannot be transferred to it.
How should Giant kelp peptide be read on an ingredient list?
Read it as the exact peptide fraction listed on the label. A shared word such as “peptide” does not make it equivalent to KTTKS or Palmitoyl Pentapeptide-4.
