The rest of the OptiBac range may contain tiny traces of dairy, as many of our live culture strains (such as Bifidobacterium infantis Rosell-33) are originally cultured on a basis of organic dairy & soy before being extracted. The rest of the range is therefore not recommended for those who are strictly vegan or allergic to dairy.

However, certain live cultures have shown to aid the body's digestion of lactose1, and the amount of dairy in our supplements is negligible, hence the whole range can be safely recommended to those who are lactose intolerant. Many of our customers with lactose intolerance happily take live cultures containing traces of lactose on a regular basis to great benefit.

The whole range is suitable for your lactose intolerant customers.
