Probiotics

Glucose and metabolic health markers is closer to a research marker, so it should be read separately from a directly felt benefit.

The 60.0 score includes research signals from patient or disease contexts. General supplement evidence is not repeated enough, so the B tier remains conservative.

Representative tier calculated from paper evidence that passed the collection audit.

Key precautions
No combination caution signal is clear enough to show right now. This does not guarantee safety.
1 combo signals and 0 added-signal combos shown below.
These are signals reported in studies. They do not predict what will happen to an individual.

Positive combinations studied

Positive combination findings are separated by how the study compared the groups. This is not a recommendation to combine them.

Positive findings when used together

The combination had a positive result, but the contribution of each ingredient could not be separated.

셀레늄Co-supplementation with probiotics and selenium resulted in significant improvements in mental health, hormonal profiles, and oxidative stress markers compared to placebo.
