personalized blend of probiotic strains, prebiotics, and botanicals
What this could lead to
If it works, this could point toward a way to ease autism-related behaviors and stomach issues using a tailored probiotic.
What could go wrong
This is a completed study without a control group, so results may be due to chance or the placebo effect. The intervention is a dietary supplement, not a drug, so any benefits are likely modest.
