I do have a vitamin D deficiency, which is why I tend to be determined to make supplementing with it work.
Hi,
When Vit D is deficient, magnesium should be tightly kept round 380 - 450 mg.Interaction of magnesium with the status of vitamin D.
“Magnesium supplementation increased the 25(OH)D3 concentration when baseline 25(OH)D concentrations were close to 30 ng/mL, but decreased it when baseline 25(OH)D was higher (from ∼30 to 50 ng/mL). Magnesium treatment significantly affected 24,25(OH)2D3 concentration when baseline 25(OH)D concentration was 50 ng/mL but not 30 ng/mL.
Conclusion: Our findings suggest that optimal magnesium status may be important for optimizing 25(OH)D status.” (6-7))

Here is one reason why your D3 supplementation isn't working.Excerpt of the post on my forum (translated)
Magnesium status influences the assimilation of vitamin D3
Key ideas
Magnesium is an essential cofactor for the synthesis and activation of vitamin D, but taking large doses of vitamin D can induce a Mg deficiency.
Some people plateau in the assimilation of active vitamin D3. We will try to understand why.
• We already knew that there was a synergy between fat-soluble vitamins but their assimilation is interconnected, and interference from the level of low-grade inflammation impacts the level of active vitamin D3.
• We have a feedback mechanism modulating the absorption of Mg, vitamin D and calcium, in order to maintain homeostasis.
• For example, magnesium would control the possible toxicity of excess vitamin D3.
• Research establishes that the Ca/Mg ratio ≈ 2:1 is optimal. However, an increased intake of unused calcium, for example following a lack of K2, can lead to an increase in urinary excretion of magnesium.
• Poor electrolyte balance can lead to autoregulation via inactivation: conversion of the active form of vitamin D to calcitriol.
Indeed, calcitriol induces the expression of 24-hydroxylase (CYP24A1) which converts 25(OH)D3 and 1,25(OH)2D3 into inactive metabolites.
Hello, thank you for this. I don't doubt that I'm magnesium deficient, and I do attempt to stay replete, but supplements are very hit and miss for me. Since starting with D3 again, I'm using magnesium oil (magnesium chloride) topically, though I'm not certain of the dose. You seem to think that the dose needs to be in that exact range. Apart from supplementing, it would be tough to know that I'm keeping it in that range. Regardless, I am attempting to get some.
