Ethos
Our mission
At BioSource, our ethos is simple: we make.
We make cultures. For nearly a quarter century, BioSource has been a trusted name in manufacturing lactic cultures for countless applications throughout the food, human and animal health, and agriculture industries. All our strains are grown in-house and on-site at our SQF-certified fermentation plant, so we can ensure that our products are consistently of the highest quality.
We make existing products better. With our focus on product improvement, we are constantly raising industry benchmarks in strain potency, stability, and purity. Through our Custom Strain Optimization program, we use our expertise to improve the potency, stability, and manufacturing efficiency of your proprietary strains. We are more than a manufacturer: our lifeblood is R&D.
Most importantly, we make our customers happy. We understand that each customer has unique needs that a “one size fits all” product listing cannot solve. Our team of dedicated microbiologists, fermentation specialists, and quality experts work with you individually to tailor a singular, scientifically backed product specific to your requirements. Our firm belief is that communication is key to excellent customer service.
