A daily multivitamin is the most essential supplement to keep in your arsenal. Here's how to find the right one:
• Make sure it includes vitamins A, C, D, E and K, as well as potassium, zinc and iodine.
• It should contain 100 percent of your daily value of most vitamins and minerals. Avoid megavitamins that may contain dangerously high levels of vitamins and minerals.
• To maximize absorption, split your vitamin in two and take half in the morning and half in the evening.
