Vivitein BLG and LF Precision-Fermented Dairy Proteins

Vivici is a precision fermentation protein company founded in 2023 and based in Oegstgeest, the Netherlands. It aims to make precision-fermented dairy protein a commercial reality and to give nutrition brands faster market access to animal-free whey proteins, drawing on experience in ingredient applications.

Its flagship Vivitein BLG is beta-lactoglobulin, the main whey protein, produced by fermentation without animals; it received an FDA GRAS 'No Questions' letter and was launched in the U.S. for B2B partners in 2025. Vivitein LF, a lactoferrin ingredient with self-affirmed GRAS status, was launched in the U.S. in 2026. Customers are food, beverage, sports nutrition and wellness brands making clear drinks, powders, bars and protein shots.

• Sports nutrition brands in Vietnam formulating clear whey drinks and protein shots.
• Beverage manufacturers developing high-protein ready-to-drink products.
• Snack makers producing protein bars with a dairy protein that is free from animal inputs.

• Lower footprint: an independent LCA cited by the company shows 68% lower carbon, 86% less water and 61% less land than milk-derived whey protein isolate.
• Real dairy functionality without animals, enabling vegan-friendly positioning.
• Regulatory readiness: FDA GRAS 'No Questions' letter for Vivitein BLG.
• Format flexibility: works in clear drinks, high-leucine powders, bars with stable texture and compact shots.

High-protein foods and drinks are one of the fastest-growing nutrition categories, while dairy protein supply is tied to herd size and emissions. Precision-fermented whey proteins let brands keep dairy performance with a lower footprint, and Asian sports nutrition and functional beverage makers are watching regulatory approvals for these ingredients.
