At Dr. Ohhira Probiotics, everything we do is rooted in years of scientific research and traditional Japanese fermentation.

We proudly stock Dr. Ohhira’s full range alongside other carefully selected, research-backed supplements that share the same commitment to quality and balance.
Dr. Ohhira’s Legacy
Dr. Iichiroh Ohhira, Ph.D., was a professor and research scientist who dedicated his life to studying how beneficial bacteria support human health. He taught and lectured across Japan, Malaysia and Korea, publishing more than 20 studies on lactic acid bacteria and their link to digestive and immune health.
Alongside a team of researchers at Okayama University, he developed a probiotic formula designed to work with the body, not against it. His work has been recognised around the world, earning:
- 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 discovered the E. faecalis TH10 strain – proven to be over six times stronger than typical lactic acid bacteria. His research shaped how we understand gut health today and continues to inspire every product that carries his name.

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.
