- Optimal Health, Vitamin D, Retinol & Magnesium-

It’s NOT about ‘High & Low’ but about Homeostasis! And optimal health only can happen when storage VitaminD (CALCIDIOL) : active VitaminD (CALCITRIOL) are in balance. The optimal ratio is 1 : 2 and Retinol (animal source Vitamin A) should be 3.5 times higher than Storage D at the same time. But to get all the ratios right you need sufficient amounts of Magnesium in your body tissue in the first place. Treat the cause!
