having been touting the benefits of magnesium recently discovered the vital connection between magnesium and vit d apparently to get the magnesium to work - magnesium to help absorb the calcium - so recently been taking magnesium and vit d with the calcium foods
Also will check hydration and oxygen intake
But have also been taking the iron tablets
interestingly our red cells need iron to transport oxygen to cells - each iron molecule has capacity for 8 oxygen molecule and vit e ensures that the iron molecules are full of oxygen - i think the magnesium helps the cell absorb minerals and vit d but also vit d helps magnesium absorb better - zinc also helps
and it seems that vit d also helps cells absorb oxygen
