Is it ok to take calcium, vitamin D3 and magnesium together? Or do calcium and magnesium compete for absorption?

Is it ok to take calcium, vitamin D3 and magnesium together? Or do calcium and magnesium compete for absorption?

OK, to a degree but:: Calcium ; magnesium are often packaged together both in supplements ; foods. They compete a bit; calcium may reduce mag. Absorption but mag. Does not seem to reduce cal. Absorption. Those low in mag. Have difficulty absorbing cal.; if deficient in mag. It may be best to take it separately. http://www.nutraceuticalsworld.com/contents/view_breaking-news/2011-09-14/magnesium-is-key-to-calcium-uptake/. ...Read more

I heard magnesium & iron compete for absorption. Is it safe to take a magnesium & iron supplement together? If not, how long should I wait in between?

I heard magnesium & iron compete for absorption. Is it safe to take a magnesium & iron supplement together? If not, how long should I wait in between?

It depends,safe,why?: Poorly absorbed forms of magnesium like mag. Oxide interfere with iron absorption whereas water-soluble forms like mag. Aspartate may not interfere- see http://www.Ncbi.Nlm.Nih.Gov/pubmed/8024640 it's safe to take together but might be prudent to take 2 hours apart. But iron deficiency is rare in men, even in men with anemia. I advise against men taking iron unless you're sure you're deficient. ...Read more

Do i take vitamin b complex with magnesium or can I take vitamin B12 ? For better absorption of magnesium. Currently also take vit D3 thanks

OK but not 4 absorb.: It is perfectly fine to take b complex/b12 with magnesium but won't enhance absorption. Magnesium is best absorbed on an empty stomach ; b vits can cause stomach upset on empty stomach. B vits, esp. B6, often work in synergy with mag. The best-absorbed forms of mag. Are glycinate ; taurate; citrate is ok too. Epsom salt baths ; topical "magnesium oil" are also good ways to get magnesium into you. ...Read more

Why is Magnesium oxide always recommended by doctors while it has the lowest absorption rate of all types of Magnesium? Why not chelated Glycinate?

Magnesium: Magnesium glycinate is a chelated form that tends to provide the highest levels of absorption and bioavailability and is typically considered ideal for deficiency. Magnesium oxide is a non-chelated type of magnesium and is less well absorbed. Why magnesium oxide is often prescribed likely has to do with its lower price and stool softening properties. ...Read more

Can i take magnesium with amino acids together? Also, what vitamins and minerals should I not take with mg. Affecting absorption?

Can i take magnesium with amino acids together? Also, what vitamins and minerals should I not take with mg. Affecting absorption?

It should not: Magnesium might interfere with some medications but not Amino Acids absorption. Why would you need to take Amino Acid supplement? Is it better that you eat a balance diet with enough protein, which would give you plenty of amino acids? It is more natural and complete variety of Amino Acids including the essential ones. Only in severe food allergy that you need a complete Amino Acid diet. ...Read more
