#236 How Full-Spectrum Light Boosts Vitamin D, Mood & Circadian Rhythm | Gerardo Gutierrez @ Mitolux

1 hour 17 minutes

Here is why sunlight feels like an instant mood shift.

Gerardo Gutierrez of Mitolux explains how UVB, near-infrared light, & full-spectrum exposure support vitamin D, hormones, circadian rhythm, & long-term energy, plus how to bioharmonize your light routine even on busy or cloudy days.

Meet our guest

Gerardo “Guti” Gutierrez is the founder & CEO of MitoLux, inspired by his own recovery from pre-diabetes, low testosterone & depression through sunlight, movement & targeted light protocols. After transforming his health in just four months, he launched MitoLux to help others do the same. Guti now teaches how UVA, UVB & red light influence biology, circadian rhythms & overall well-being.

Key takeaways

Sunlight supports mood, hormones, energy, circadian rhythm, & overall health, far more than just vitamin D

Modern light therapy panels replicate broader sunlight spectra, including UVB, red, & near-infrared wavelengths

Avoiding sunlight raises health risks similar to chronic smoking due to missing vital biological pathways

Sun-created vitamin D lasts longer & delivers deeper benefits than supplements for mood, hormones, & neurotransmitters

LED lighting lacks infrared that mitochondria need, while older incandescent bulbs support healthier light balance

Indoor LED exposure creates infrared deficiency, reducing mitochondrial function & overall energy

Natural sunlight pairs UVB with protective infrared, helping prevent aging & supporting safe vitamin D synthesis

Darker skin needs more sunlight for healthy vitamin D because melanin & geography influence exposure needs

Morning & sunrise light prime the body for UV later by boosting melanin & reducing sunburn risk

Gradual, consistent sun or panel exposure builds a “solar callus,” supports health, & prevents skin damage
