Why is magnesium poorly absorbed without vitamin D?

Magnesium and vitamin D are closely related in metabolic processes:

• Vitamin D is involved in regulating the synthesis of receptor proteins and enzymes that are involved in the transport and absorption of magnesium.

• If there is a low level of vitamin D in the body, the activity of magnesium transport systems decreases, and magnesium absorption may not be as effective.

• On the other hand, taking high doses of vitamin D without adequate levels of magnesium can lead to magnesium deficiency because vitamin D increases the body's need for it.

Therefore, magnesium is better absorbed with sufficient levels of vitamin D.

Conversely, vitamin D works more effectively in the presence of adequate amounts of magnesium. Magnesium is an activator of vitamin D. Without it, vitamin D cannot be converted into its active form. Enzymes that depend directly on sufficient levels of magnesium in the body are necessary for this.

Therefore, the intake of vitamin D should be accompanied by the consumption of at least 250-500 mg of magnesium.
