Infants (0–12 Months)

Biostime's infant range includes probiotic drops, synbiotic powder sachet, and targeted defense formulas designed for babies from birth through 12 months. Each product is formulated with clinically studied probiotic strains and selected for its specific role — from daily gut and immune support to skin and nasal comfort.* Products vary by format, age range within the 0–12 month window, and added ingredients such as vitamin D or HMO prebiotic, so parents can choose based on their baby's needs.

Select Biostime infant products are suitable from birth (0 months), including the Baby Colic Vitamin D + Probiotic Drops. Other products in the range, such as the Daily Probiotics + HMO Prebiotic powder, are suitable beginning at 3 months of age. Each product page specifies the recommended age range. As with any supplement, we recommend consulting your baby's pediatrician before starting.

Biostime offers both formats to suit different stages and preferences. The probiotic drops are a liquid format that can be mixed into breast milk or formula, or applied to the breast before feeding — making them well-suited for newborns. The powder sachets are tasteless and dissolve easily into any liquid or soft food at room temperature, and are suitable for babies are suitable beginning at 3 months of age. Both formats deliver clinically studied probiotic strains to help support healthy gut microbiome development.*

Prebiotics are non-digestible fibers that help feed and support the growth of beneficial bacteria in the gut. Biostime's Daily Probiotics + HMO Prebiotic formula includes 2'-FL Human Milk Oligosaccharide (HMO) — a prebiotic structurally similar to one found in most breastmilk — to help support gut balance and healthy immune function.* Products that combine probiotics and prebiotics in a single formula are sometimes referred to as synbiotics.

A significant portion of the immune system is influenced by the gut microbiome. Biostime's infant formulas contain clinically studied probiotic strains that help support a balanced gut microbiome, which in turn helps contribute to healthy immune function in infants.* Consistent daily use is recommended to support this ongoing process from the earliest months.

Vitamin D plays an important role in helping the body absorb calcium, supporting healthy bone and muscle development in infants.* Many infants — particularly those who are exclusively or partially breastfed — may benefit from a daily vitamin D supplement. Biostime's Baby Colic Vitamin D + Probiotic Drops combines 400 IU (100% of the daily value for infants) of vitamin D with clinically studied probiotic strains in a single daily serving.

Yes. Biostime's infant drops can be mixed into breast milk, formula, or administered by spoon, and the powder sachets dissolve easily into any liquid or soft food at room temperature. Neither format should be mixed with hot liquids or foods, as heat can diminish the effectiveness of the probiotic cultures. Do not administer drops directly into baby's mouth.

Allergen profiles vary by product. The Baby Colic Vitamin D + Probiotic Drops do not contain milk, eggs, peanuts, tree nuts, fish, crustacean shellfish, wheat, sesame,or soy. The Daily Probiotics + HMO Prebiotic powder contains dairy and soy. Always check the individual product page for the full allergen and ingredient information before purchase.

Biostime has over 20 years of scientific research and expertise in microbiome health. Each product undergoes rigorous quality control, including raw material testing, auditing of FDA-registered manufacturing facilities, and independent laboratory testing of finished products. Biostime is also a certified B Corp, reflecting its commitment to quality, transparency, and responsible practices.

The right product depends on your baby's age and specific needs. The Baby Colic Vitamin D + Probiotic Drops are designed for babies from birth and are a good option if you're looking for a 2-in-1 formula that also supports vitamin D intake. The Daily Probiotics + HMO Prebiotic powder is suitable from 3 months and includes an HMO prebiotic for added gut support. The Baby & Kids Defense formulas address skin and nasal comfort specifically.* If you're unsure, we recommend consulting your baby's pediatrician to find the best fit.
