The next evolution in salmon peptide nutrition — six unique bioactive peptides sourced from the pristine northern seas of Hokkaido, Japan, refined through years of clinical research and backed by 8 international patents.

SOP Subarashi Gold is a premium Japanese superfood supplement produced by AFC Japan, developed through rigorous clinical research and representing the evolution of AFC's flagship SOP product line.
Where the earlier SOP 100+ contained a single peptide — Salmon Ovary Peptide — SOP Subarashi Gold features six distinct bioactive peptides working synergistically, delivering a significantly more comprehensive nutritional profile for daily wellness support.
The key ingredients in SOP Subarashi Gold are found only in the northern seas of Hokkaido, Japan — a region renowned for its cold, mineral-rich waters that produce exceptionally high-quality marine nutrients. These ingredients are formulated based on years of scientific research conducted in Japan and the United Kingdom.
An important note on exclusivity: the Salmon Ovary Peptide (SOP) ingredient is used exclusively under special rights granted directly by its discoverer, Prof. Tadashi Eto, PhD — making SOP Subarashi authentically unique among wellness supplements worldwide.
SOP Subarashi Gold holds 8 international patents — the result of collaborative research between Japan and the United Kingdom. Obtaining a patent requires years of longitudinal clinical research and must meet stringent qualification criteria. Below are 4 of the 8 functional patents:
