is magnesium or calcium more active?

Calcium is slightly more active than Magnesium, because the outer 2 electrons experience greater repulsions from the inner electrons in Calcium than they do in Magnesium. As such, the removal of the outer electrons requires less energy.

Mg2+ and not Mg2-\nThis ion lacks 2 electrons to be neutral, so it is positively charged.

As noted from others, exercise and proper calcium levels are a must.  Dairy is not the best source of calcium: the best are kale, collards, spinach and calcium-fortified soymilk.  The best way to get proper levels of calcium and the vitamins and minerals that go along with bone building is with proper digestion.  If you have a history of indigestion/heartburn, and especially if you take antacids or acid decreasing drugs, you must get digestion working properly.  This includes proper levels of acid in the stomach.  This is necessary for calcium absorption.  Look for a company named Standard Process.  They can direct you to a doctor who can help with digestion.  If you are female, proper balancing of hormones is vital as well.  Get checked out by a doctor who uses natural-based medicine.  Good luck!

Calcium is essential in muscle contraction, oocyte activation, building strong bones and teeth, blood clotting, nerve impulse transmission, regulating heartbeat, and fluid balance within cells. In the U.S., between about 50% and 75% of adults do not get sufficient calcium in their diet. Adults need between 1,000 and 1,300 mg of calcium in their daily diet.

Ah the great calcium question!!! I will try to give you a little insight to this.  We think we need alot of calcium to create bone and prevent bone loss.  It is true that we need it...but if you think about it, North America is the BIGGEST consumers of dairy and calcium supplements in the world, yet we have the highest rates of osteoporosis....HMMMM I wonder why...well, according to research that I have been reading, the main reason we are so calcium deficient is cuz we are too acidic... Meaning we eat too many "acid forming" foods. And of course the acid "forming" foods are sugar, meats, dairy (ironically enough) chocolate, coffee, artificial flavors and sweeteners, and tap water or water that has no minerals like distilled.  We MUST eat 80% of our diet ALKALINE (all veggies, fruits, and some grains and seeds) and 20% acidic.  We seem to have it the opposite.  your body will do ANYTHING to stay alkaline, thus it will pull calcium from your bones.\n\nTo answer your question, anything in excess is not good.  Too much calcium will cause bone spurs, kidney stones, will aid in hardening the arteries and cause digestive upset.  The recommended daily doseage is about 1000-1200mg of calcium a day.  At least half of that should come from your diet.  A cup of spinach has 280mg of calcium.  2 tablespoons of tahini (ground up sesame seeds) has about the same amount.  Try sardines, molasses, dark leafy greens and sea vegetables like wakame, kelp, or arame.  Soy has alot too.  Taking a few hundred mg's of calcium in supplements is a good idea too, if you do however I recommend a 1:1 ration of equal calcium and magnesium because about 90% of the population is deficient in magnesium.  Also try to get one with vitamin D and Zinc and Boron.  Hope this helps, sorry it was so long, I am trying to better the lives of people with my knowledge ;)\n\nhttp://www.vaxa.com/736.cfm\nhttp://www.naturalhealthschool.com/acid-alkaline.html\nhttp://www.betterbones.com/research/ph_studies.htm\nhttp://www.liferesearchuniversal.com/acid.html\n\nthese are all good sites to check out on the subject\nSmile and love your body!!

Calcium is the chemical element in the periodic table that has the symbol Ca and atomic number 20. Calcium is a soft grey alkaline earth metal that is used as a reducing agent in the extraction of thorium, zirconium and uranium. Calcium is also the fifth most abundant element in the Earth's crust. It is essential for living organisms, particularly in cell physiology, and is the most common metal in many animals.\n\nIT MAKES YOUR BONES STRONGER - and prevents osteoporosis

Yes you need magnesium and plenty of it.  and also vitamin D\n \n\nbut also Zinc, Silicon, boron are needed.  Trace minerals matter.\n\nvitamin D capsules are cheap and better to take than food sources.   reliable and easy to take and use.

Magnesium is a mineral that is required by every cell of your body. At least half of the magnesium in your body is found in combination with calcium and phosphorus in your bones. The other half of your body's magnesium stores are found inside cells of body tissues and organs. About 1% of the magnesium in your body is found in your blood. Magnesium is needed for more than 300 biochemical actions in your body that control muscle contraction, nerve function, heartbeat, energy production, and protein synthesis.

You are right there are many different calcium supplements on the market. It can be confusing. Here are some things to look for: \n1) Look for bioavailable sources of calcium (i.e. calcium  carbonate and calcium citrate). \n2) Vitamin D is extremely important for absorption. \n3) Don't settle for calcium alone - look for other bone-building nutrients in the supplement, with magnesium the most important. Trace minerals like manganese, copper and zine can be important as well.\n4) Avoid high doses. Any single dose should not exceed 500mg of calcium as the body cannot effectively deal with more at any one time. \n5) Find a tablet that is designed to physically break down in the body. This has been a problem with some calcium supplements.\n6) Look for supplements only from credible companies that do good scientific research and clinical testing. Not all supplements are made the same.\nMy wife and I use OsteoMatrix, as it is the best that we have found.

It has recently been discovered, after a large medical study, that most people who suffer from chronic headaches have low levels of magnesium.  A high percentage of the people in the study noticed a significant decrease in the frequency and severity of their headaches after they started taking magnesium supplements.  So if I were you, I'd give it a try.  You've got nothing to lose -- except the pain.

Both the systems are different.Ther is no direct connection between both these two systems\nBut one important thing that is VIT  D .It is most important for bone growth and density of calcium in the bones.VIT D can be actively produced by the body in the presence of ultraviolet rays from sun. and vit D it goes in to blood stream and promote the bone growth.Nothing more than that

I agree with the previous answer; magnesium nitrate is probably more soluble, at 125 g/100 mL water versus magnesium chloride's 54.2 g/100 mL.  Nitrate's ionic bond (not "bound") is weaker probably because of its higher electron density pulling away from that bond.  \n\nSolubility rules tell us that all nitrates are soluble, but silver, mercury, and lead chlorides are insoluble.

All active metals whose activity is more than H react with water under some or the other condition. For eg. Na metal reacts violently with cold water(the colder the better) liberating hydrogen gas which ignites due to the heat produced in the reaction whereas Mg shows a similar reaction with hot water. The energy liberated is due to the Hydration enrgy which gives the respective metal hydroxides. Even dissolution is a slightly exothermic.
