What it is & primary uses
Live microorganisms whose effects depend on the exact genus, species, strain, dose and clinical context.
Main benefits
- Specific strains can help specific outcomes, including some antibiotic-associated diarrhea contexts.
- The word probiotic alone does not predict efficacy, and one strain cannot substitute for another.
Studied protocols
Research doses are grouped by outcome. They describe study designs—not a personal prescription.
No universal gram dose; verify strain and CFU through shelf life
- Study duration
- Commonly 4–12 weeks; protocol and outcome vary
- Interpretation
- The word probiotic alone does not predict efficacy, and one strain cannot substitute for another.
04Food sources & equivalents＋
Can food provide a studied amount?
Yogurt, kefir and other fermented foods contain variable live cultures can provide related dietary exposure, but food and extract milligrams are not automatically interchangeable.
Dietary exposure; verify composition before comparing with a studied supplement dose
- How this was estimated
- Dose Radar compares the declared active ingredient with official composition data or the studied standardized extract—not with marketing names.
- Important limitation
- Natural content, preparation, bioavailability and formulation vary. This comparison does not prove equal physiological effect.
Food equivalents compare ingredient mass using published composition values. They do not prove equal absorption, formulation, physiological effect, safety or personal need.

With or without food
Human research has not established a universally superior fed or fasted protocol for this ingredient.
- Practical approach
- Follow the strain-specific product or trial protocol. Keep the formulation and daily total consistent with the evidence context shown above.
- Watch for
- Antibiotic timing
Meal guidance reflects human pharmacokinetic, clinical, official-label or evidence-review sources where available. A food pairing can change absorption or tolerability, but does not make a supplement necessary, effective or safe for every person.

An unlisted pair means no established pair-specific interaction was identified in this review—not proof that every dose, product or person is safe.
This is not proof that every dose, product or user context is safe. Medication and condition checks still apply.
07Research notes＋
Moderate evidence for the stated context. The word probiotic alone does not predict efficacy, and one strain cannot substitute for another.
The displayed amount comes from human research or an official evidence summary. It is not a personalized prescription, and formulation can change whether the comparison is valid.

This live index supports source verification. A new paper does not change the Dose Radar grade until its design, population and formulation are reviewed.
09Expert & media references＋
Podcast and practitioner statements are clearly separated from research. They may explain practice or emerging ideas, but do not prove efficacy.
