Members don't see this ad.

In the 2016 edition (don't have a page number because I have e-book) does anyone else think the diagram showing PTH and vitamin D activity is misleading? It looks like it shows 1,25 (OH)2D3 stimulating increased Ca2+ and PO43- from bone as in bone resorption, but it's supposed to stimulate bone mineralization.

It stimulates bone deposition indirectly by increasing the concentrations of calcium and phosphate. However, at higher concentrations, vit D cause bone resorption directly. Goal is to increase calcium/phosphate.

I see, thank you
