Well, you need to learn about synergy. Synergy is a term that describes the way combining vitamins, minerals and antioxidants together can increase or decrease the body’s ability to absorb and use minerals that otherwise have trouble getting passed into the bloodstream. Oftentimes the issue has to do with how strong mineral molecules are and if they can stay together to pass through the intestinal wall.
Combinations that increase absorption of minerals:
Vitamin D helps the body absorb calcium, and phosphorous, and magnesium. These are very important to keep the bones from being brittle.
Compounds in onions and garlic help the body absorb iron, zinc and copper.
Vitamin K helps the body absorb calcium.
