Toddlers (1–3 Years)

Biostime's toddler range includes four powder formulas in single-serving sachet format, each designed for a specific area of everyday wellness. The Daily Probiotics + Prebiotics with Vitamin D supports digestion, gut flora, immune function, and bone health.* The Daily Probiotics + HMO Prebiotic is a synbiotic formula that combines probiotics with a 2'-FL HMO prebiotic structurally similar to one found in breastmilk.* The Dual Defense formula targets nasal and respiratory wellness in addition to gut and immune support.* And the Skin Defense formula addresses skin comfort from the inside out.* All products are formulated with clinically studied probiotic strains and are suitable for toddlers from age 1.

A synbiotic is a supplement that combines both probiotics (beneficial bacteria) and prebiotics (fibers that feed those bacteria) in a single formula. For toddlers, this combination helps support a more balanced gut environment by delivering beneficial microorganisms alongside the nutrients they need to thrive.* Biostime's toddler powders use prebiotic ingredients such as FOS (fructooligosaccharide) and 2'-FL HMO, each selected for their role in supporting gut health during early childhood.*

Probiotics are live microorganisms that help support a healthy balance of bacteria in the gut. During the toddler years, the gut microbiome is still developing, and daily probiotic supplementation can help maintain healthy gut flora, support comfortable digestion, and contribute to everyday immune function.* Biostime's toddler formulas contain clinically studied probiotic strains chosen for their relevance to early childhood gut health.

2'-FL (2'-Fucosyllactose) is a Human Milk Oligosaccharide (HMO) — a type of prebiotic structurally similar to one found in most breastmilk.‡ It is included in select Biostime formulas to help support gut balance and healthy immune function.* Parents who are still breastfeeding or using HMO-fortified formula should not give a product containing 2'-FL HMO on the same day, to avoid exceeding the appropriate intake — individual product pages provide specific guidance.

The right product depends on your toddler's primary needs. For everyday gut and digestive support, either the Daily Probiotics + Prebiotics with Vitamin D or the Daily Probiotics + HMO Prebiotic is a good starting point — the key difference being the prebiotic ingredient (FOS vs. HMO) and the inclusion of vitamin D in the former. If your toddler experiences seasonal nasal or respiratory discomfort, the Dual Defense formula is specifically formulated to support those areas alongside gut and immune health.* For skin comfort support, the Skin Defense formula is designed for that purpose.* We recommend consulting your child's pediatrician if you're unsure which product is the best fit.

The gut plays a meaningful role in overall immune function, and Biostime's toddler formulas are formulated with this connection in mind. Each product contains clinically studied probiotic strains that help support a healthy gut microbiome, which in turn helps contribute to everyday immune health in young children.* The Dual Defense formula also includes specific strains targeted at supporting the body's response to seasonal changes and environmental irritants.*

Yes — all Biostime toddler powders are flavorless and fast-dissolving. Each single-serving sachet can be mixed into any cool liquid or soft food at room temperature, making them easy to incorporate into meals or snacks without altering taste. They should not be mixed with hot or warm foods or liquids, as heat can diminish the effectiveness of the probiotic cultures.

Allergen profiles vary by product. The Daily Probiotics + Prebiotics with Vitamin D and the Daily Probiotics + HMO Prebiotic both contain dairy and soy. Neither contains gluten, wheat, eggs, peanuts, fish, shellfish, or tree nuts. For the Dual Defense and Skin Defense formulas, allergen details are listed on the individual product pages. Always review the full ingredient and allergen information before purchase, particularly if your child has known food sensitivities.

Every Biostime product undergoes rigorous quality control — including raw material testing, auditing of FDA-registered manufacturing facilities, and independent laboratory testing of finished products. Biostime draws on over 20 years of scientific research in microbiome health and is a certified B Corp. Ingredients in the Daily Probiotics formulas are sourced from France.

Yes. Biostime's toddler formulas are designed for daily use and can be incorporated into your child's everyday routine. Each product provides a 28–30 day supply per box. As with any supplement, consult your child's pediatrician if you have questions about long-term use or if your child has an underlying health condition.
