Mal-illumination is the term coined by photobiology pioneer, Dr. John Ott to describe this “indoor” syndrome that’s akin to malnutrition. We now spend most of our days indoors unwittingly, starving for essential natural light that our genes are programmed to respond to.

Being stuck in “biological darkness” due to reduced time in appropriate natural light profoundly affects every body system. Most of us do not spend enough time in “full-spectrum” sunlight that augments immunity and spend most of our time indoors under unhealthy “limited spectrum” light that adversely impacts immunity.

Research has also shown that ingested foods, vitamins and supplements require a full-spectrum of light in order to be fully metabolized. Without the right light —absorption is incomplete and nutrients are partially wasted and less effective.

Sadly, good hygiene has overlooked the need for daily “light hygiene” required to nourish and regulate brain chemistry and circadian rhythms that control:

  • mood
  • appetite
  • energy
  • sleep
  • libido and so much more

Ideally, everyone should properly regulate their daily exposure to natural light, managing the time spent inside and out to naturally enhance immunity and reduce the risk of disease.


  • Help prime retinal cells for repair & regeneration.
  • Aids the production of ATP in the mitochondria. ATP is the fuel cells need for all vital functions.
  • Essential for subcellular as well as circulatory melatonin production.
  • Especially beneficial at night to prepare for sleep.
  • A “must” when using computers and other electronic screens.
  • May also be used as needed during the day for an energy boost much like coffee.

  • 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
