Bifidobacterium bifidumProbiotic
Live probiotic bacterium of the Bifidobacterium genus, commonly used for digestive and immune support. Strain-specific evidence base in IBS, antibiotic-associated diarrhea, and infant colic.
Capsule ShellCapsule
Generic capsule shell where the label does not specify the material. Common materials are hypromellose (HPMC) for vegetarian capsules and gelatin for traditional capsules — both are GRAS-listed and safe. Fish gelatin and pullulan variants also exist.
Lactobacillus acidophilusProbiotic
Live probiotic bacterium native to the human GI tract and found in fermented foods. NCFM and La-14 are the most-studied strains with RCT evidence for digestive health, antibiotic-associated diarrhea, and lactose tolerance.
Lactobacillus plantarumProbiotic
A lactic-acid bacterium used as a probiotic strain.
Lactobacillus rhamnosusProbiotic
One of the most-studied probiotic species. The LGG strain (ATCC 53103) has the largest RCT evidence base of any probiotic — digestive health, antibiotic-associated diarrhea, eczema prevention in at-risk infants.

How to Take It
Best taken in the morning
Live strains survive stomach acid best taken with or just before a meal — after a meal is the worst option. Consistency matters more than the clock.
With food
Keep it away from hot food or drink
On the label
For best results, we recommend taking one capsule a day. It’s not good on an empty stomach, so make sure you have it 30 minutes before or after food.
The label says to take it on an empty stomach. What's in this one sits better with food, and you give up little by taking it that way.
General guidance based on the ingredients, not a substitute for the label or your doctor.
