Most people—and even many doctors—don’t realize:

The standard blood test for vitamin D measures 25-hydroxyvitamin D [25(OH)D] — a storage form, not the active form your body actually uses.

This test reflects:

  • How much supplemental D3 you’re taking
  • Or how much sunlight your skin has converted

But it says nothing about:

  • Magnesium status, which is essential to activate vitamin D
  • Whether it’s being converted into 1,25-dihydroxyvitamin D — the active hormonal form
  • Whether it’s being properly balanced by Vitamin A and Vitamin K2
  • Whether your body is using it effectively in your immune, hormonal, skeletal, and neurological systems

That’s why you might have a “normal” vitamin D test — yet still feel exhausted, get sick easily, suffer mood swings, experience hormonal chaos, or even develop soft tissue calcification (calcium building up in arteries or organs).


Scientific Evidence Behind This:

  • Magnesium is critical for the activation of vitamin D.
    Without enough magnesium, vitamin D remains in its storage form, unable to regulate calcium or support immune function.
    Reference: “Magnesium, Vitamin D Status and Mortality: Results from US NHANES 2001–2006 and NHANES III” — Deng X. et al., BMC Medicine, 2013.
  • Over-supplementing vitamin D without magnesium can worsen deficiency symptoms.
    Supplementing D without adequate magnesium increases soft tissue calcification and disrupts calcium regulation.
    Reference: Rude RK et al., “Magnesium Deficiency: A Cause of Heterogeneous Disease in Humans” (Journal of Bone and Mineral Research, 1998).
  • Vitamin A and K2 balance the actions of vitamin D.
    Taking vitamin D alone, especially at high doses, without retinol (A) and K2, can lead to calcium being deposited in arteries and joints instead of bones.
    Reference: Masterjohn, C., “On the Trail of the Elusive X-Factor: A Sixty-Two-Year-Old Mystery Finally Solved,” Wise Traditions, 2007.
  • Forrest Maready’s research (especially in The Moth in the Iron Lung and his work on cod liver oil) explains that vitamin A from cod liver oil historically protected children from bone deformities and respiratory diseases—not synthetic vitamin D alone.

A Better Way to Nourish Vitamin D Pathways:

  • Cod Liver Oil:
    One of the only whole-food sources naturally providing:
    • Vitamin D
    • Retinol (Vitamin A)
    • Omega-3 fatty acids (EPA/DHA)
    • In the correct ancestral ratios
  • Magnesium Chloride (Transdermal):
    • Supports activation of Vitamin D into its hormonal form
    • Regulates calcium transport
    • Reduces systemic inflammation
    • 80% absorption rate through the skin without burdening the gut

Together, they restore the entire pathway—without the guesswork, without synthetic isolates, and without creating nutrient imbalances that damage long-term health.


The Real Truth:

You’re not “low” on vitamin D just because of a lab number.
You’re low because modern nutrition has severed you from ancestral wisdom—the way your body was designed to absorb and use nutrients: whole, balanced, and synergistic.
