Is the BioGaia Protectis Drops worth it?
BioGaia Protectis Probiotic Drops
The rare supplement whose bottle matches its trials — same strain, same dose, ~25 min/day less crying at day 21 — but the benefit is concentrated in breastfed infants with colic, formula-fed evidence is insufficient (the largest trial found no benefit), and $24.99 buys a stated 25 days (~$30/month).
See current price ↗The pitch
The most researched probiotic for infant colic — patented L. reuteri Protectis (DSM 17938), 100 million live CFU in 5 drops once daily, shown to reduce crying time, in sunflower oil with a neutral taste
The catch
The pooled benefit (~25 min/day less crying/fussing at day 21) is concentrated in breastfed infants with colic — in formula-fed infants the evidence is insufficient and the largest trial (n=167) found no benefit and more fussing; it is an unapproved dietary supplement, not a colic cure, and owners report bottles that dispense hard and may not yield the stated 25 servings
FSA/HSA
only with a Letter of Medical Necessity — probiotics are supplements under IRS rules, not eligible for general gut health
What it is
A probiotic dietary supplement in oil drops: one strain, Limosilactobacillus reuteri (formerly Lactobacillus reuteri) DSM 17938 — BioGaia’s patented Protectis strain — in sunflower oil. The dose is 5 drops once daily, a minimum of 100 million live CFU, given by spoon, on the breast, or in breast milk or formula. That is exactly the strain and dose used in the colic trials, which is the strongest thing about this check. The 5 mL bottle is stated as 25 servings (~25 days). It is a dietary supplement, not a drug: its statements have not been evaluated by the FDA, and there is no FDA efficacy approval behind it — the case rests entirely on the published trial record. This check summarizes published evidence only and is not medical advice.
Claims vs. reality
Colic / crying time — the real claim, split by feeding type: Savino et al. 2010 (50 exclusively breastfed colicky infants) found median crying of 35 vs. 90 minutes/day on placebo at day 21. Sung et al. 2018 (Pediatrics) pooled raw data from 4 double-blind trials (345 infants): 25.4 min/day less crying/fussing than placebo at day 21, ~1.7× the treatment-success rate — but effects were dramatic in breastfed infants (number needed to treat 2.6) and insignificant in formula-fed infants, with insufficient data to conclude. The largest single trial, Sung et al. 2014 (BMJ, n=167, breastfed and formula-fed), found no benefit — the probiotic group cried or fussed 49 min/day more than placebo at 1 month, mainly extra fussing in formula-fed infants. The measured endpoint is crying time over 21–28 days in infants with colic — not a cure (colic resolves on its own by ~3–4 months, and placebo groups improved too). Spit-ups, occasional constipation & diarrhea: printed under the same FDA asterisk, with nothing like that record — Savino 2010 found no group differences in stooling, constipation or regurgitation. Gut/immune framing: the colic trials measured crying time and stool microbes, not immune outcomes such as fewer infections. Strain and dose: verified — the bottle names the exact studied strain at the exact studied dose; a generic L. reuteri drop cannot borrow this record.
Safety & recalls
No CPSC recall names BioGaia or Protectis, and no FDA recall of this product was found (checked Nov 1, 2026) — supplements have no FDA premarket approval, so no record is not a clearance. In the term-infant colic trials, no supplementation-related adverse events were reported (Savino 2010; Sung 2014). The brand’s own label says “Not intended for use in premature infants.” The FDA’s 2023 warning is a category caution, not a BioGaia finding: it warned that preterm infants given probiotics in hospital settings risk invasive, potentially fatal disease, citing one 2023 death — a preterm infant under 1,000 g given a different product (Evivo with MCT Oil, Infinant Health; Bifidobacterium longum sepsis genetically matched to it) — plus more than two dozen reported adverse events since 2018 in that hospital preterm setting, and stated the FDA has approved no probiotic as a drug or biologic in infants of any age. The AAP has no recommendation endorsing probiotics for colic; its position quoted by the FDA is about preterm infants (no routine universal use, particularly under 1,000 g).
Real reviews — what owners say
Owner sentiment is as split as the trials. Target’s summary of the plain version calls feedback mixed: some owners call it a game changer for gas and constipation (one saw stools and comfort worsen within two days of running out, after ~1.5 weeks to see results); others report no improvement at all after weeks at the label dose, and a recurring minority report more gas and fussing, runny stools, or new constipation. iHerb’s far more positive pool (4.9/5, ~20,000 ratings) is for the different Vitamin D version and a global self-selected audience — not evidence about this plain US bottle. Taste is a non-issue (neutral, given by spoon or in milk). The practical complaints repeat: price for the quantity (Skroutz 3.9/5, 264 reviews), drops that get hard to dispense near the end, no dropper — and one Target owner reporting two bottles in a row lasting only 12 days, not the stated 25 servings (a single owner’s pattern, flagged, not a verified fill measurement).
Price & FSA/HSA
$24.99 for the 5 mL bottle at biogaia.com (the with-Vitamin D version is $32.99 — check which bottle is in the cart). At the stated 25 servings that is $1.00 per day, ~$29.99 per 30 days — about $30/month, or ~$21 for one 21-day trial-length course. If a bottle yields fewer servings, as owner reports describe, the effective cost rises: at 12 days a bottle it would be ~$62/month, which is why the dispensing complaints are a value issue. There is no cheaper evidence equivalent: the trial record belongs to this named strain, so a cheaper untested drop is not the same comparison. FSA/HSA: not eligible as a general purchase — probiotics may be eligible only with a Letter of Medical Necessity tying them to a diagnosed condition (IRS Publication 502 treats supplements for general health as non-qualified); plan acceptance of an LMN for this product was not verified.
The rare supplement whose bottle matches its trials — same strain, same dose, ~25 min/day less crying at day 21 — but the benefit is concentrated in breastfed infants with colic, formula-fed evidence is insufficient (the largest trial found no benefit), and $24.99 buys a stated 25 days (~$30/month). Worth It If…
