More info on ages and stages

The strains in our probiotic formulas work in synergy. Our belief is that no single strain is the magic bullet for specific ailments and conditions. This is because they should work together, as they do in a healthy digestive system.

You can find more info below, including ages and stages for each of our probiotic formulas.

Please keep in mind that the age to progress from one formula to another varies. Since everyone is unique and responds differently, it's important to also consider the individual's health history, diet, metabolism, and practitioner recommendations. And, our customer service team is here to answer your questions if you need further help choosing. 😊

Infant Probiotic

Our Infant Probiotic powder is recommended for anyone under the age of 2. However, because it's such a gentle formula, it's also ideal for sensitive individuals of all ages or those taking probiotics for the first time. It’s our least potent formula.

The Infant Probiotic contains seven clinically-proven strains of beneficial bacteria naturally found in the digestive system of a healthy infant, and comprises 50% Bifidobacterium infantis. This strain is special because it dominates in breastfed babies' intestines, as it thrives on a unique molecule from breast milk. In scientific studies, B. infantis has been linked to healthy digestion, growth and immunity in infants.

Sensitive Probiotic

The Sensitive Probiotic powder is best for ages 3 and over, or children between the ages of 2 and 3 who have already used the infant formula. It contains one extra strain (L. plantarum) and is twice the potency of the Infant Probiotic. Smidge® Sensitive Probiotic is a powerful formula that does not require large doses. However, it’s suited for sensitive individuals who may have reacted to certain strains of bacteria found in other probiotic formulas.

Many of our customers with histamine intolerance, digestive issues, skin problems and other health conditions begin with our Sensitive Probiotic powder. In all, it’s for those who are serious about gut health: a clean, potent, therapeutic-grade probiotic with eight strains of beneficial bacteria essential for digestive health, and no additional ingredients. This product is also available in capsules.

Optimal Probiotic capsules
