Why It Works

Key Benefits

🦠
10 Billion CFU per Strip
The label lists Bifidobacterium lactis 37.5 mg, equal to 10 billion CFU, per strip (serving size: 1 strip, 180 mg). The label names the species only, with no strain, and probiotic effects are strain-specific, so results from studies of particular B. lactis strains cannot be applied to this product. CFU is a count of live organisms and does not by itself show an effect. The abstracts of the cited body-weight meta-analyses give no probiotic doses, so the 10 billion CFU cannot be compared with trial doses. The supplier describes the product as tested in-house; no CFU count at the end of shelf life is given.
🌾
Prebiotic Fiber: Polydextrose
The label lists 50 mg of polydextrose per strip, a fiber the supplier describes as a prebiotic. In a human feeding study, polydextrose at 8 g per day changed the composition of the fecal microbiota. A strip contains less than 1% of that amount, and no study at this dose was found.
👅
Dissolving Strip Format
The suggested use is to place one strip on the tongue and let it dissolve before swallowing, once daily. Flavor is mixed berry. No published study of this strip, of how many bacteria it delivers alive, or comparing strips with capsule probiotics was found.
📋
Other Ingredients and Sugar Alcohols
The label also lists pullulan, cellulose, mannitol, mixed berry flavor, sunflower lecithin, monk fruit extract, erythritol, medium chain triglycerides, malic acid and steviol glycoside. The strip weighs 180 mg and the two active ingredients make up 87.5 mg, so all other ingredients together weigh at most 92.5 mg. Mannitol and erythritol are sugar alcohols; a systematic review found that polyols can cause dose-dependent flatulence, abdominal discomfort and laxative effects, and in a trial single doses of 20 g and 35 g of erythritol did not provoke a significant increase in symptoms. A strip contains far less than those amounts. Check the list if you have an allergy or sensitivity.
✅This product is for you if…
You prefer a dissolving oral strip to a capsule
You want a product containing Bifidobacterium lactis (strain not stated) and polydextrose, a prebiotic fiber
You have checked with your doctor or pharmacist if you take regular medicines or have a medical condition
⚠️Consult your healthcare provider if…
You are pregnant or breastfeeding. Ask your doctor or pharmacist first
You are under 18. The supplier's warning says to consult a healthcare professional first. Premature infants and newborns: this product is not intended for them
You have a weakened immune system (for example organ transplant or chemotherapy). Ask your doctor first
You have a central venous catheter or other indwelling line, or you are seriously ill or in intensive care. Rare bloodstream infections linked to probiotic bacteria have been reported. Ask your doctor first
You have severe acute pancreatitis or another serious pancreas condition. A trial of a multispecies probiotic in predicted severe acute pancreatitis found higher mortality. Ask your doctor first
You take prescription medicines (including diabetes, weight-management or immune-suppressing medicines) or have a medical condition. Ask your prescriber or pharmacist first, and do not change or stop any prescribed medicine on your own
You are sensitive to sugar alcohols (mannitol, erythritol) or have irritable bowel syndrome or another digestive condition. Polyols can cause gas, discomfort and a laxative effect at higher doses; one strip contains at most about 0.09 g of all other ingredients combined. Ask a clinician if unsure
You are allergic or sensitive to any ingredient on the label (for example sunflower lecithin, pullulan, monk fruit, erythritol or mannitol)

Science

Clinical Evidence

Published research relevant to this product. These studies were generally not conducted on this specific product.

🔬
An expert consensus statement reinforced the definition of a probiotic as live microorganisms which, when administered in adequate amounts, confer a health benefit on the host, and called for more precise use of the term to help clinicians and consumers tell apart the diverse products on the market.
Hill C et al. Nat Rev Gastroenterol Hepatol, 2014;11(8):506-14. ↗
🔬
A meta-analysis of 15 randomized trials (957 people with overweight or obesity, 3 to 12 weeks) found probiotics were associated with a larger reduction in body weight (0.60 kg) and BMI (0.27 kg/m2) than placebo, but the effect sizes were small, and the effect on fat mass was not significant.
Borgeraas H et al. Obes Rev, 2018;19(2):219-232. ↗
🔬
A meta-analysis of 11 randomized trials (911 people with overweight or obesity) of Bifidobacterium-genus probiotics, excluding mixtures, found lower body fat mass (0.64 kg), body fat percentage, waist circumference (1.39 cm) and visceral fat area, but no significant difference in BMI, body weight or waist-to-hip ratio. The authors state that more research is needed on strain and species interactions, dosages and delivery methods.
Hamed Riveros NF et al. J Am Nutr Assoc, 2024;43(6):519-531. ↗
🔬
In a double-blind, placebo-controlled crossover feeding study in healthy people, polydextrose at 8 g per day increased some fecal bacterial groups (Ruminococcus intestinalis and bacteria of the Clostridium clusters) and decreased the Lactobacillus-Enterococcus group; less abdominal discomfort was recorded during polydextrose consumption. The dose was far higher than the 50 mg per strip listed for this product.
Costabile A et al. Br J Nutr, 2012;108(3):471-81. ↗
🔬
A review of probiotic risks concluded that probiotics have an excellent overall safety record but should be used with caution in certain patient groups, particularly neonates born prematurely or people with immune deficiency, and that the effects of one probiotic strain should not be generalized to others without confirmation in separate studies.
Boyle RJ et al. Am J Clin Nutr, 2006;83(6):1256-64. ↗
🔬
A review of probiotic safety stated that safety outcomes are inconsistently reported in clinical trials and that described theoretical risks include systemic infections, excessive immune stimulation in susceptible individuals and gastrointestinal side effects; more research is needed on the incidence and severity of adverse events.
Doron S et al. Clin Infect Dis, 2015;60 Suppl 2:S129-34. ↗
🔬
A review found Lactobacillus bacteremia to be infrequent but with higher mortality and risk factors that include severe underlying disease, immune suppression, intensive care admission and central venous catheters. It was more common in people taking probiotics than in those not taking them. These findings concern Lactobacillus and not Bifidobacterium.
Kullar R et al. Microorganisms, 2023;11(4):896. ↗
🔬
A systematic review of 79 articles found that polyol malabsorption occurs in a dose-dependent fashion in healthy people and increases when polyols are eaten together, and that polyols can cause dose-dependent flatulence, abdominal discomfort and laxative effects in healthy volunteers and in people with irritable bowel syndrome; moderate doses shifted the microbiome toward more bifidobacteria in healthy people
Lenhart A, Chey WD. Adv Nutr. 2017;8(4):587-596. ↗
🔬
In 64 healthy young adults, single doses of 20 g and 35 g of erythritol in water did not significantly increase gastrointestinal symptoms compared with 45 g sucrose, while 50 g increased nausea and borborygmi; xylitol at 35 g and 50 g produced watery faeces. One strip of this product weighs 180 mg in total

Science behind this product

Strain-specific effects: A probiotic is defined as live microorganisms that give a health benefit when taken in adequate amounts. A safety review noted that the properties of probiotic species vary, can be strain-specific, and should not be generalized to other strains without separate studies. The label names Bifidobacterium lactis but not a strain, so results from studies of particular B. lactis strains cannot be applied to this product. Hill 2014 · Boyle 2006

Probiotics and body weight: A meta-analysis of 15 trials (957 people with overweight or obesity) found small reductions in body weight (0.60 kg) and BMI compared with placebo, and the authors described the effect sizes as small. A meta-analysis of 11 trials of Bifidobacterium probiotics (911 people with overweight or obesity; mixtures excluded) found lower body fat mass and waist circumference but no significant change in body weight or BMI. These findings depend on the strains and doses studied. This product was not tested and is not a weight-loss product. Borgeraas 2018 · Hamed Riveros 2024

Polydextrose: In a placebo-controlled human feeding study, polydextrose at 8 g per day changed the composition of the fecal microbiota. Each strip contains 50 mg, less than 1% of that amount, and no study at this dose was found. Costabile 2012

Strip format: No published study of this strip, of how many bacteria it delivers alive, or comparing strips with capsules was found in PubMed.

Dose and sweeteners: The abstracts of the two body-weight meta-analyses above do not state the probiotic doses used, so this page cannot compare the 10 billion CFU per strip with them. The strip weighs 180 mg, of which the label's two active ingredients make up 87.5 mg, so all other ingredients together, including the sugar alcohols mannitol and erythritol, weigh at most 92.5 mg (about 0.09 g). A systematic review found that polyols (sugar alcohols) can cause dose-dependent flatulence, abdominal discomfort and laxative effects, and that malabsorption increases when several are eaten together Lenhart 2017. In a trial in healthy adults, single doses of 20 g and 35 g of erythritol in water did not provoke a significant increase in symptoms, while 50 g increased nausea and borborygmi Storey 2007. The amounts in one strip are far below those doses, but people who are sensitive to sugar alcohols should check with a clinician.

Probiotic safety: Reviews describe probiotics as generally safe for most people, but they note that systemic infections have been reported in susceptible people, including those with immune deficiency, severe underlying disease or central venous catheters, and that caution is advised for premature infants.
