Although we aim to consume a diverse variety of fruits, vegetables, nuts, dairy, and meat, sometimes we fall short on micronutrient intakes. While nothing replaces a nutrient-rich diet, multivitamins are an extremely inexpensive way to cover nutritional deficiencies arising from eating the same or similar foods day to day or week to week.
Multivitamins are offered in powder, liquid, capsule, tablet, and softgel forms. The formulations vary slightly on the target demographic; such as teen, child, male adult, female adult, senior, or athlete. When selecting a multivitamin look for high-quality, bioavailable and easily-absorbed forms of vitamins and minerals.
Many top-tier multivitamins also include bonus ingredients beyond vitamins and minerals that are designed to support whole-body health and support specific systems in the body. This article discusses the key vitamins and minerals, common bonus ingredients, as well as provides a brief description of 8 popular high-quality multivitamin supplements.
Key Vitamins in a Multivitamin FormulaVitamins are classified in to one of the following two categories: water-soluble and fat-soluble. Water-soluble vitamins dissolve in water and must be taken daily because they are not stored in the body.  Example of water-soluble vitamins include vitamin C and the following B vitamins: thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), biotin (B7), folate (B9), B6, and B12. 
don't be alarmed if you multivitamin has more than 100%, more than 1,000%, or even more than 10,000% of your daily value of these water-soluble vitamins. To These vitamins are not stored in the body tissues so the excess is simply excreted via sweat, respiration, and urination. Consume with water to maximize their absorption.
Fat-soluble vitamins dissolve in fat and include vitamins A, D, E, and K. While it is okay to consume more than 100% of these vitamins on a daily basis you should exercise caution when consuming excessively high amounts over a long period of time. The body?s fat cells stores excess quantities of these vitamins. If left unmonitored your body may accumulate toxic levels of these vitamins which may lead to health complications.
Choose supplements with vitamin A sources of beta-carotene and retinyl palmitate, a vitamin D source of cholecalciferol (D3), a vitamin E source of alpha-tocopherol or mixed Tocopherols, and a vitamin K source of menaquinone (K2).  Consume with a fat source to maximize their absorption.
Key Minerals in a Multivitamin FormulaThe body does not naturally produce minerals so they must be consumed via food and supplement sources. A high-quality multivitamin should include most if not all of the following minerals: calcium, iron, iodine, magnesium, zinc, selenium, copper, manganese, chromium, molybdenum, and potassium.
Calcium, magnesium, and iron are typically dosed in very low quantities (<20%) in multivitamins. This is to minimize excess calcium and iron build-up in the blood as well as eliminate the likelihood of experiencing magnesium-induced gastrointestinal issues. The remaining minerals may be dosed anywhere between 25% and 300% of the recommended daily value.
Ensure your multivitamin uses chelated forms of magnesium, zinc, selenium, copper, manganese, chromium, molybdenum. While multivitamins with chelated minerals typically carry a higher price, rest assured you?re ingesting the high-quality and most bioavailable forms of these minerals. Minerals can be consumed with or without food but be careful when consuming high amounts calcium, magnesium, and zinc at the same time as these three compounds compete on the same pathway to be absorbed.
Bonus IngredientsMost multivitamins provide you with 100% or more of the recommended daily value of key vitamins and minerals.
