Answer a few quick questions to find the TABREAK device that fits your needs.
Find Your Device → →Start with a simple guide to red and near-infrared light, how they work, and how to build a safe, consistent routine.
Start Learning → →Every cell in the body needs energy to perform its normal functions. Much of this usable energy is produced inside structures called mitochondria.
Photobiomodulation (PBM) research explores how specific wavelengths of red and near-infrared light may interact with these energy-related cellular processes.
Cells are the body's smallest working units.
Your skin, muscles, joints, nerves and organs are all made up of different types of cells. Although each cell has a different role, they all require energy to function normally.
Cells use energy for many everyday processes, including:
Without a continuous energy supply, cells cannot carry out these normal biological functions.
Inside most cells are tiny structures called mitochondria.
They are often known as the "powerhouses of the cell" because they convert nutrients and oxygen into usable cellular energy.
Rather than storing energy like a battery, mitochondria work more like a miniature energy factory—continuously producing the energy that cells need throughout the day.

ATP
ATP stands for adenosine triphosphate.
It is the primary molecule cells use to store and transfer energy.
Cells rely on ATP for many normal activities, including:
A simple way to think about ATP is that it acts as the cell's energy currency, allowing energy to be transferred wherever it is needed.
During photobiomodulation, specific wavelengths of red and near-infrared light reach the tissue.
Some of this light may be absorbed by light-sensitive molecules inside cells. Researchers believe mitochondria are one important area of interaction.
This light signal may influence:
Research is ongoing, and the biological response depends on factors such as wavelength, light dose and tissue type.
Healthy cells require a reliable supply of usable energy.
Because ATP supports many normal cellular activities, cellular energy production has become an important area of photobiomodulation research.
However, ATP is only one part of a much larger biological response. Other cellular signaling pathways may also contribute to how cells respond to light.
For this reason, researchers study PBM as a complex biological process rather than focusing on ATP alone.
PBM does not directly give the body energy. Instead, it may support the cellular processes involved in producing and managing energy.
Mitochondria help produce ATP, and ATP helps power the normal activities that keep cells functioning.
