Dr. Mercola: Whole Food Multivitamin PLUS, 240 tabs

However, with my unique Multi +Plus formula, you’ll benefit from many specially selected minerals… including these 3 essential ones:
• Calcium — To provide a high-level of support for your skeletal system, I chose to include a high amount of calcium in the Multivitamin +Plus Vital Minerals formula*. My main reason for doing this was that, as you age, your need for calcium becomes more and more important to promote healthy bones*.
A recent study published in The American Journal of Clinical Nutrition reported that people should consume 741 mg per day of calcium to maintain neutral calcium balance.
Realizing the importance of eating as much unprocessed whole food as possible to get the minerals you need, my Multivitamin +Plus Vital Minerals formula provides 500 mg of calcium to complement your healthy diet.
• Magnesium — Scientific studies have reported that magnesium is helpful in supporting your lungs and overall pulmonary system*. But some lower-potency multivitamins don’t include this ingredient.
Other research shows that magnesium intake promotes bone density health.* It also helps maintain your muscular and nervous systems.* And helps support a healthy heart, and your energy needs.*
So you can see why magnesium is such a key mineral in my Multivitamin +Plus Vital Minerals formula.
• Potassium — This important mineral helps regulate your circulatory system and promotes your heart health.*
In addition, research has shown that potassium is another important element in your bone density health.* As you age, bone density becomes an important element in your overall health.*
Many processed foods lose valuable potassium content prior to ever reaching your table.
