It's difficult to label live cultures as organic, as the term 'organic' generally refers to plants grown or animals reared under strict organic standards. Generally speaking, crops and animals are considered healthier when grown and reared organically, and organic produce is thought to be better for their health. However, the same concept does not apply to microbial cultures like the ones that OptiBac Probiotics offers. Live cultures and S. boulardii are single-celled and therefore much more simple in their structure and function than the fruits, vegetables, grains & meat they consume. Live cultures are not thought to be affected by the fermentation medium on which they are grown (the 'food they eat'), and therefore whether it is organic or not will not make any difference to the quality of the bacteria.
