Episode 42: An Expert’s Guide to Red Light Therapy, Dosing, and Myths with Andrew LaTour of GembaRed

This episode explores the practical science behind red light therapy with Andrew LaTour, founder of GembaRed. Andrew and Elizabeth Abela break down what matters in photobiomodulation, how to evaluate devices, and why popular advice often misses the basics.

Andrew shares his journey from childhood health challenges and chemical engineering to discovering biohacking in 2015 and launching GembaRed in 2018. He explains why he built the company around affordability, transparent specifications, and evidence-based education rather than marketing hype.

We explore red and near-infrared wavelengths, mitochondrial support, ATP production, inflammation, and the evolution from low-level laser therapy to LED devices. Andrew explains why light can have systemic effects beyond the area being treated, including the gut, brain, bones, sternum, and other body sites.

The conversation gets practical: wavelength, irradiance, total power, joules per square centimeter, dosing, distance, skin contact, flicker, and why inexpensive meters can produce misleading measurements. Andrew explains the biphasic dose response—why more light is not necessarily better—and how overheating can signal excessive intensity.

We also discuss eye and skin safety, tattoos, pregnancy, cancer precautions, circadian timing, morning versus evening use, and why sunlight remains essential. Andrew distinguishes red light therapy from chromotherapy, far-infrared lighting, photodynamic therapy, lasers, and other commonly confused modalities.

Finally, Andrew addresses industry myths, copycat claims, transparency, and why accurate information matters when choosing devices.
