Nutritionists agree that there are seven essential ingredients that should be included in a multivitamin. These include vitamin D, magnesium, and the 13 essential vitamins. Vitamin D helps the body absorb calcium, which is important for bone health. Magnesium is an essential nutrient that must be obtained from food or supplements.
Vitamins help the body grow and function properly. The 13 essential vitamins are A, C, D, E, K, and the B vitamins (thiamine, riboflavin, niacin, pantothenic acid, biotin, B6, B12 and folate). Folic acid is added to certain foods to help people get enough of this important vitamin. Vitamin D is also important for absorbing calcium and preventing certain types of cancer and heart disease.
The main source of vitamin D is the sun, so people who live in high latitudes or have darker skin pigmentation may be at risk for low levels of this vitamin. Eating fish or taking a supplement can help increase vitamin D levels. Vitamin A is important for vision, skin health and immunity. It can be found in preformed vitamin A (retinol) and beta-carotene.
While severe vitamin deficiencies are not common, some people may not be getting enough of these five vitamins. The remaining B vitamins are B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid) and B7 (biotin). These vitamins are not considered essential because they do not fit the definition of “essential” that was discussed earlier. If you think you may have a vitamin deficiency, it is best to talk to your doctor about it.
They may order tests to determine if you need to take a supplement or make changes to your diet. Companies like OmegaQuant offer at-home tests to detect vitamins and nutrients such as vitamin D and Omega-3 EPA and DHA. The three most important vitamins for your health are vitamin D, vitamin A, and the B vitamins. Vitamin D helps the body absorb calcium and prevents certain types of cancer and heart disease.
The B vitamins are important for energy production and metabolism.
