Hi Daniel... As advertised... if your magnesium is low, then calcium will be elevated. If you aren't taking supplemental magnesium regularly, you should start with low dosing and increase the amounts and timing every 3 - 4 days... letting bowel tolerance be an indicator. Sometimes, you have to back down and dose less aggressively at first until your system acclimates.
Using the amino acid chelated form of magnesium... magnesium glycinate or bis-glycinate... offers the least chance of developing bowel tolerance issues rapidly... (Look for the registered trademark TRAACs
(R) which indicates it is the true amino acid chelated product by Albion Labs. Some people get along with magnesium gluconate and magnesium sulfate or various combinations but be aware that magnesium citrate is the form that produces laxation so when that happens, less magnesium reaches the target which is inside the cells. You can also consider making and drinking the magnesium bicarbonate water - which we call Waller Water or WW to ensure alkalinity and also provide a highly beneficial source of magnesium from that ion.
Amounts required are highly individualized depending on usage, needs, health of receptor sites on cells, etc. It can take 3 - 4 months and longer to optimize your intracellular magnesium levels. Plus, various influences deplete magnesium quickly... excess fat, sodium, sugar, protein, alcohol, phosphates in sodas and caffeine... also medications including diuretics, insulin, antibiotics, GERD drugs (PPIs and H2 blockers), and for women, hormone replacement therapy and birth control.
Also limit foods high in calcium. Cardiologist, Thomas E. Levy, MD, JD says in his book "Death by Calcium"... that:
"Proof of the toxic effects of dairy and calcium supplements, attention should be given to reduce consumption of calcium-containing foods; increase magnesium with supplements and avoid using calcium supplements. He says: “low magnesium elevates calcium and increases all-cause mortality from heart disease and cancer and also makes those diseases worse. Few things can impact your health as profoundly as properly supplemented magnesium.”
