FAQ for OEM buyers

Q. What are the specific lactotripeptide sequences and their origin?

The two main milk-derived lactotripeptides used in Japanese functional foods are Val-Pro-Pro (VPP) and Ile-Pro-Pro (IPP), produced by Lactobacillus helveticus fermentation of milk casein. Calpis (Asahi Group) holds historical IP around the production process for FFC/FOSHU applications.

Q. What is the regulatory status for blood-pressure claims in Japan?

Lactotripeptides have FOSHU (Tokuho) approval for 'helping maintain healthy blood pressure for those with mildly elevated blood pressure' as well as multiple FFC notifications. Buyers must follow the exact approved claim language and dose for each product.

Q. What is the typical functional daily dose?

FOSHU/FFC blood pressure products typically deliver 3.4 mg of VPP+IPP combined per day, often in a single 100-200 mL drink or tablet serving. Dose must match the specific notification.

Q. Are there milk-allergen labeling considerations?

Yes — because lactotripeptide is derived from milk casein, all products containing it must declare 'milk' as an allergen under Japan's mandatory allergen labeling regulations (and equivalent rules in EU/US). This applies even to highly purified peptide preparations.
