Broken mitochondria don’t just stop making energy. They leak ROS.
ROS, short for reactive oxygen species, is the oxidative stress your mitochondria give off when cellular energy production runs rough. Researchers associate high ROS levels with fatigue, slow recovery, and faster aging. Most people have never measured their mitochondrial function at all.
mescreen is an at-home mitochondrial test that measures mitochondrial efficiency, cellular respiration, and ROS levels, both at baseline and under stress, from a single blood spot. It shows how well your mitochondria are actually turning fuel into ATP, your body’s energy.
The Deuterium Test is an at-home saliva test that measures your deuterium level. Deuterium is heavy hydrogen found in all water and food, and researchers are studying its link to mitochondrial oxidative stress.
At-home. Both tests. One bundle. The simplest way to get a real baseline for your mitochondrial health, energy levels, and oxidative stress.
