Near infrared light
For mitochondrial health and cellular energy
The experts we follow agree on this.

Near infrared light supports mitochondrial repair and energy, especially after exercise.
Who is behind it
Voices including a molecular biology PhD, an optometrist of twenty years and a board-certified cardiologist.
How strong the research is
Well studied in published research, as well as in practice.
In their words
“NIR light directly stimulates the production of ATP (energy) and deuterium depleted metabolic water by the mitochondria. NIR light is an ESSENTIAL NUTRIENT for mitochondria in almost every cell of the body.”
a Princeton-trained molecular biology PhD
Near infrared light supports mitochondrial function and melatonin production for repair after exercise stress
NIR light activates molecular chaperones that refold proteins and clear waste in retinal pigment epithelium cells without drugs.
Near infrared light penetrates bone and is useful for brain photobiomodulation but should be used cautiously to avoid overuse.
With care
Some of the minds attach conditions. These are worth reading before you begin.
Near infrared light penetrates several millimeters into tissue via scattering rather than absorption, which is distinct from visible light behavior.
Talk it through
Entrain shows what the experts teach, so you can make better decisions with your own clinician. It does not diagnose or prescribe. If something is worrying you, start there.
How this reading was made
Every line here comes from a doctor, scientist or coach speaking publicly, and links to the moment they said it. Entrain listens for where independent experts arrive at the same place on their own, and shows where they part ways. Well studied in published research, as well as in practice.
None of the statements here come with a declared commercial interest. Last refreshed 9 August 2026.
