About Dr. Ohhira Probiotics
Backed by research. Rooted in tradition.
At Dr. Ohhira Probiotics, our approach brings together scientific research and traditional Japanese fermentation. Developed by microbiologist Dr. Iichiroh Ohhira, the formulas are created using a carefully controlled fermentation process designed to support digestive balance and overall wellbeing.
Our range includes Dr. Ohhira’s probiotic formulas alongside other carefully selected supplements that share the same focus on quality, balance, and thoughtful formulation.
Dr. Ohhira’s Legacy
Dr. Iichiroh Ohhira, Ph.D., was a professor and research scientist who dedicated his career to studying beneficial bacteria and their role in human health. He lectured across Japan, Malaysia, and Korea, and contributed to published research on lactic acid bacteria and digestive wellness.
Working with researchers at Okayama University, he developed a probiotic formula designed to complement the body’s natural systems through slow, multi-year fermentation.
His work has been recognised with awards including:
- Best Product Award – Japanese Dairy & Food Association
- International Best Alternative Medicine Gold Medal – Global Health Manille ’98
- Scientist of the Year – Japanese Dairy & Food Association
Dr. Ohhira also researched the E. faecalis TH10 strain, which has been studied for its stability and activity compared to certain lactic acid bacteria strains. His research continues to influence the philosophy behind the products that carry his name.

6. What makes Dr. Ohhira different from other probiotic brands
6. What makes Dr. Ohhira different from other probiotic brands
They’re award-winning for a reason. While most probiotics are freeze-dried or formulated in days, Dr. Ohhira’s are naturally fermented for up to five years - a process that strengthens the bacteria and creates a blend of pre-, pro-, and postbiotics all in one capsule.
It’s this traditional, time-intensive method, combined with decades of scientific research, that makes Dr. Ohhira’s one of the most respected probiotic brands in the world.
