Guide by goal
Supplements for digestion
The 1 actives in the library that the quiz considers when your goal is digestion, ordered by the strength of their evidence, with their reference dose. Their profiles link to 2 studies.
What the evidence says for each
The level of evidence sums up everything known about each active, not just for this goal. What there is specifically for digestion is in the studies on its profile.
| Active | Evidence | Reference dose | What is known |
|---|---|---|---|
| Probiotics | Promising | Depending on the strain: usually 1–10 billion CFU a day. | The effect depends on the strain: there are positive trials with specific strains for digestive discomfort and regularity, but not all probiotics do the same thing. |
How to choose
An active appearing here does not mean you need it. The quiz combines this goal with the rest of your answers and only suggests the ones with enough reasons, without repeating actives that do the same thing.
Each profile explains the form, time of day, what to check on the label, precautions and studies. If a problem persists or worries you, see a healthcare professional: a supplement is no substitute for that.
