The human body is a combination of cells and chemicals that comes to life only when —LIGHT— “nature’s electricity” is present.
RECHARGE ~ REGULATE ~ REGENERATE.

Being stuck in “biological darkness” due to reduced time in natural light — that our genes are programmed to respond to — profoundly affects every body system.
Modern humans (in developed nations) do not spend enough time in full-spectrum sunlight that augments immunity and spend most time indoors under unhealthy, limited-spectrum light that adversely impacts immunity.
Most indoor lighting and devices such as video screens are actually detrimental to this light-loop. They do not supply the correct wavelengths of light that are essential to naturally regulate brain chemistry and often have photobiotic qualities that tend to compromise immunity.
Curiously, good hygiene (for most people) has overlooked the essential requirement for daily, light hygiene required to regulate brain chemistry and circadian rhythms that control:
- appetite
- energy
- mood
- sleep
- libido
- other body-mind functions.
“We are all light deficient and this deficiency may be the source of our physical and emotional problems.”
— DR. JOHN OTT

Ideally, everyone should properly regulate their daily exposure to light, managing the time spent inside and out to naturally enhance immunity and reduce the risk of disease.
For those times when it’s not convenient to balance your exposure to sunlight . . .
- SOL PhotoVites are akin to vitamins that are required for normal cell function, growth and development.
- SOL PhotoVites provide photo-nutrients that “ignite” and support optimum metabolic functioning.
