No plants here. L. plantarum, a plant-based strain, is omitted in Smidge® Infant Probiotic because L. plantarum is a very potent strain that increases the potency of a probiotic formula. Because Smidge® wanted the infant formula to be less potent than the original Sensitive Probiotic powder, they did not include it. Customers with worries about d-lactate production may also prefer the omission of L. plantarum as it produces a small amount of d-lactate. However, it's important to remember that it helps balance the production of L-lactate.
