Obtaining Optimal Levels of D3

Skin Exposure
  • Exposure: Expose 85% of your skin for 30 minutes (light-skinned) - 2 hours (dark-skinned) a day to mid-day sun.
  • Skin Color: Optimal exposure is gauged the color your skin turns. A light pink is ideal. After that no further D is produced
    and will only be damaging the skin.
  • Preserve the D Skin Oils: Because the body needs 30-60 minutes to absorb these vitamin D-containing oils, it is best to
    delay showering, bathing, or swimming in a chlorinated pool for one hour after exposure.
  • Natural D3 Dosage: Adequate sun baths will produce about 20,000 IUs of D3. With longer exposure to UV-B rays, an
    equilibrium is achieved in the skin, and the vitamin simply degrades as fast as it is generated. Thus one cannot overdose
    (only burn the skin) from sunlight exposure.

Supplements
  • If sun exposure is not possible due to work, or winter cold, it is essential to take 2-4,000 IUs of a D3 supplement. I
    recommend mercola.com Vitamin D3 Spray.
  • Tanning Beds: Use only if you can certain that the tubes did leak x-rays, and are insulated from producing
    electromagnetic fields.
  • There is very wide variability between people's uptake capacity of D3. The only sure way to determine how much D3 IU's
    to take by supplement form is by getting a blood test of D3 levels; and comparing several of those against supplement
    intake. A safe amount for all people is believed to be 2-4,000 IU.

Nutritional Information
  • D3 can be stored up to about 2 - 2 and 1/2 months in the body.
  • Oils/Fats - D3 is fat-soluble so you must make sure you get enough fat/oils daily.
  • Vitamin A competes with D3 for uptake. If a Vitamin A supplement is taken it should first of all be from a natural source,
    not synthetic which will destroy to the liver; and, the dosage should not exceed 6,000 IU. I recommend just getting it
    from food sources like carrots, spinach and chlorella.
  • Antioxidants: It is also important to eat many antioxidant foods when consistently sunning (recommended in daily
    diet/supplements below) as exposure produces many free radicals. It is no coincidence that plants that we eat are high
    in AOX.

Photobiology
  • Sunlight that enters the eyes stimulates the production of many hormones of the brain. It regulates the cicadian cycle
    (wake-sleep cycle). It is important to get at least 1 hour's exposure of sunlight through the eyes (obviously not by
    looking directly at the sun, but also glasses/sunglasses/contacts block the beneficial UV rays).

Blocking the Sun; Artificial Tans
  • Sunscreen contains many toxic chemicals and should never be worn.
  • Sunglasses should only be worn for one reason: to mitigate glare (e.g. from cars, water, etc.).
  • Glass Blocks UV-B: UV-B is the essential radiation wavelength that effects D3 production in cells. It is blocked by glass. So
    sitting in front of your window in the winter will not work! Glasses and contact lenses also block UV-B from entering the
    eyes.
  • Tanning Beds: Although tanning beds emit UV-B wavelengths, the tubes also leak x-rays, and the entire bed emits a
    large extremely polluting electromagnetic field.
