Overview

Life Start 2 is a probiotic supplement primarily aimed at supporting gut health in infants, containing Bifidobacterium longum infantis and a small amount of Vitamin C. While B. infantis has demonstrated efficacy in reducing the risk of NEC and diarrhea in infants, the benefits for adults and older children are less well-established. The inclusion of vitamin C is at a low dose. The product also contains goat milk and brown rice, which may pose allergen concerns.

The Good

Contains Bifidobacterium longum infantis, a beneficial probiotic for infants.

Guaranteed potency of live active bacteria through expiration if refrigerated properly.

Can be easily mixed with formula or non-acidic juice for infant consumption.

The Bad

Limited evidence for benefits in adults; primarily studied in infants.

Requires refrigeration to maintain potency.

Contains goat milk and brown rice, which may be unsuitable for individuals with allergies or dietary restrictions.
