Biosciences & Nutrition SolutionsFermented Vitamin A

Fermented Vitamin A

Vitamin A is one of the most essential micronutrients across human and animal health — critical for vision, immunity, skin integrity, and cell growth. LCY's fermentation-derived vitamin A delivers the same biological activity as conventional sources, with a more consistent purity profile and a significantly lower environmental footprint.



Aulixir™ Fermented Pro-Retinol


Not encapsulated retinol. Not retinol made more cleanly. A naturally esterified retinoid — a structurally distinct molecule produced by a patented yeast strain that fuses Vitamin A directly to a bioactive carrier oil during fermentation.
