Selenium and Vitamin E

• Taking selenium with vitamin E increases the heart-healthy benefits of the vitamins.
  
  

Folic Acid and B Vitamins

• Folic acid, which is especially important for pregnant women during the first trimester, works best when taken with B6 and B12.
  
  

Calcium and Magnesium

• Calcium comes from many sources, but none of it can be processed without magnesium. Those with particular calcium needs should also take additional magnesium.
  
  

Zinc and Copper

• The body needs a little copper to use the zinc commonly taken to fight a cold or flu. Most foods enriched with zinc also contain some copper.
  
  

Warning
