Red and near-infrared (NIR) light are especially beneficial for joints and muscles due to their ability to boost cellular energy and collagen production. [1-5].

ENHANCED CELLULAR ENERGY (ATP)

Mitochondria—the cell’s “power plants”—can generate ATP using both glucose and light. Red and NIR light specifically enhance the final step of the Electron Transport Chain, increasing ATP output. This light-driven energy production fuels tissue repair, improves joint function, and supports muscle recovery.

Red/NIR light also improves oxygenation and blood flow by breaking the bond between nitric oxide and cytochrome c oxidase (COX), a key mitochondrial enzyme. This promotes faster recovery and reduced discomfort in joints and muscles

COLLAGEN SUPPORT

Collagen makes up nearly 30% of the body’s protein and is essential for strong connective tissue. Red/NIR light stimulates fibroblasts to produce more collagen, supporting joint stability and muscle integrity.
