HelloPharmacist Scorecard of Jarro-Dophilus Infant 1 Billion CFU by Jarrow Formulas

Four independent checks of what is known — a summary of the available information, not a grade of the product itself.

Evidence for Intended Use
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

The stated purpose hasn't been mapped to our evidence data yet.

Why this rating?
  • We haven't mapped this product's purpose to our evidence data yet — it'll be graded on the next content refresh.
Ingredient Transparency
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.
Known Interaction Concern
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Bifidobacterium Longum.
  • The most serious interaction on file is rated Moderate.
  • For scale: 182 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.
Safety Information
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.

Assessment coverage: 1 of 1 active ingredient matched to our full ingredient reviews (monographs). Based on the product label dated Jan 24, 2024.

Formula

Bifidobacterium Longum Subsp. Infantis M-63 Bifidobacterium longum subsp. infantis (B. infantis) is associated with improved growth, the development of intestinal membrane integrity, and is critical for developing immune system. B. infantis is the predominant intestinal organism found in breast-fed infants. B. infantis M-63 was isolated from a healthy infant and clinically proven to colonize the intestines of infants. B. infantis is the only bacterial species to utilize Human Milk Oligosaccharides (HMOs) components made by fermentation (such as 2'-FL and 3'-SL), which allows B. infantis to outcompete other species. Jarro-Dophilus Infant is formulated with medium chain triglycerides (MCT), which are naturally present in breast milk and are more easily absorbed by the newborn’s immature digestive system.

Clinically studied B. infantis M-36 Liquid probiotic

The developing intestinal microflora of a newborn is up to 90% B. infantis.

Antibiotic Drugs

Theoretically, taking Bifidobacterium longum with antibiotic drugs might decrease the effectiveness of B. longum.
Since B. longum preparations usually contain live and active organisms, simultaneously taking antibiotics might kill a significant number of the organisms. Tell patients to separate administration of antibiotics and B. longum preparations by at least 2 hours.
