About ProTren

About Us

Welcome to ProTren, your trusted source for precision probiotics, available exclusively to licensed healthcare professionals and their patients. Our commitment to offering a diverse range of precision probiotics, not found in stores, underscores our dedication to enhancing client retention within your practice.


At ProTren, we recognize the uniqueness of each patient, as unique as their individual fingerprints. To address these distinct needs, we provide a selection of precision probiotic powders and capsules meticulously crafted for the patients under your care.

Founded and led by probiotic pioneer Natasha Trenev, President of ProTren, our legacy stems from a rich family history of producing the most beneficial yogurt, cherished by the royal family of Yugoslavia for over 750 years. Natasha's extensive knowledge and experience have significantly contributed to the evolution of the probiotics industry. Graduating from UCLA in 1970, she spent a decade in research, culminating in the development of the first revolutionary method for producing a scientifically validated, single-strain probiotic bacteria product. Natasha's efforts played a pivotal role in establishing the entire globtal probiotics category.
