Summary

This study looked at whether taking a probiotic called L. plantarum can help your body absorb more sulforaphane, a healthy compound found in broccoli. Thirteen healthy adults took either the probiotic or a placebo for two weeks, then ate a broccoli supplement. Researchers measured sulforaphane levels in their urine and blood to see if the probiotic made a difference.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Lactobacillus plantarum probiotic and broccoli sprout extract
What this could lead to
If it works, this could point toward a simple dietary strategy to increase the health benefits of eating broccoli.
What could go wrong
This is a very small, early-stage study in healthy people, so results may not apply to the general population or lead to any practical advice.
