Natasha Trenev

Natasha Trenev, Founder & President of Natren

Probiotic pioneer, Natasha Trenev, has significantly contributed to the evolution of the probiotics industry. Prior to her work in the field, consumers had very limited knowledge of the supplement and its many benefits. Natasha's extensive experience and knowledge of the industry began with her family's 750-year history producing the most beneficial yogurt prized by the royal family of Yugoslavia.


After graduating from UCLA in 1970, a decade of research led to Natasha's development of the first revolutionary method of producing an effective and scientifically validated single strain probiotic bacteria product. Her efforts helped to establish the entire probiotics category in the world!
