L‑92® is a patented, heat‑killed form of Lactobacillus acidophilus developed by Asahi Group Foods. Originating from the celebrated CALPIS® line (established 1919), L‑92® builds on a century of probiotic research. This strain has been self-affirmed as GRAS in the U.S. and is widely used in dietary supplements and functional foods across Japan, the U.S., and Europe.

L-92® stands out in the functional ingredient space due to its robust clinical backing, excellent safety profile, and adaptability for various demographic groups—including infants (from 10 months), children, adults, and even pets. Its unique mechanism of action makes it particularly suitable for conditions where immune regulation is critical, such as allergies, skin conditions (e.g., atopic dermatitis), and respiratory health.

Supported by over 20 years of research, L-92® has been featured in peer-reviewed journals, randomized controlled trials, and commercial products globally, making it a trusted option for next-generation immune health support.
