Can a rise in sunlight exposure cause magnesium depletion?

I have recently learned that taking vitamin D supplements can cause a dip in magnesium, because Mg is used as a cofactor to process the vitamin.

Does this apply to a sudden lifestyle change from very little exposure to lots of exposure to sunlight?

(I am asking this as a purely theoretical question about physiology etc, and not as medical advice for myself or others).

I can't help but notice sunlight is not mentioned as a cause of Mg deficiency.

That's not quite accurate.

See the article: Magnesium Supplementation in Vitamin D Deficiency (in American Journal of Therapeutics)

Background: Vitamin D and magnesium (Mg) are some of the most studied topics in medicine with enormous implications for human health and disease. Majority of the adults are deficient in both vitamin D and magnesium but continue to go unrecognized by many health care professionals.

Mg is essential in the metabolism of vitamin D, and taking large doses of vitamin D can induce severe depletion of Mg. Adequate magnesium supplementation should be considered as an important aspect of vitamin D therapy.

Taking large doses of Vitamin D is the important factor, and it can also lead to hypervitaminosis D and subsequent toxicity and organ damage.

Vitamin D toxicity, also called hypervitaminosis D, is a rare but potentially serious condition that occurs when you have excessive amounts of vitamin D in your body.

The objective should be to have the right or healthy balance of vitamins and minerals in the body, and if at all possible, get some sun exposure on the skin.
