Mixed Evidence

Hydrilla provides a mix of minerals and phytonutrients; specific human clinical outcomes are not well established.

How it works

Hydrilla is dense in chlorophyll, carotenoids, B-vitamins, and a wide range of minerals including calcium, magnesium, and trace elements. Its nutritional density is what underpins its use as a 'super-green' ingredient. Specific clinical outcomes from hydrilla supplementation have not been widely characterized in controlled trials.
