Vitamins are essential for the body to maintain good health and function properly. However, there are some vitamins that should not be taken together and some medical conditions where people should avoid taking certain vitamins or minerals. To make sure that your dietary supplement does no more harm than good, it is important to understand which vitamins should not be taken together. Fat-soluble and water-soluble vitamins have different absorption rates.
Vitamin D is a fat-soluble vitamin that is better absorbed with food, while B-12 is a water-soluble vitamin that should be taken on an empty stomach. Vitamin C and vitamin D must also be taken at different times.
Calcium and Vitamin D
are two important minerals that the body needs to function optimally. Calcium is essential for strong bones and teeth, as well as a healthy heart, while vitamin D plays an important role in calcium absorption.Unfortunately, approximately 40 percent of the U. S. population is deficient in vitamin D, which can lead to a condition called iron deficiency anemia, whose symptoms often include extreme fatigue, weakness, and lethargy.
Calcium and Iron
should not be taken together as calcium can affect the way the body absorbs iron.The National Institutes of Health found that the body may not be able to absorb iron effectively when an iron supplement is taken in combination with a calcium supplement. To avoid this problem, it is recommended that people taking both supplements take them several hours apart.
Calcium and Zinc
can also interact with each other as calcium can affect the absorption of zinc and magnesium. While it's OK to take them together in a multivitamin complex (which typically contains smaller doses of these minerals), it's best to space out these supplements if you take them individually.Vitamin A
is found in many different foods, so supplementation is generally not necessary.Pregnant women who get too much vitamin A can have serious birth defects, so it is recommended that women of child-bearing age avoid taking multivitamins or other supplements that contain vitamin A.
Vitamin B12
is important for converting food into energy, maintaining healthy cells and tissues in the body, and helping to form new blood cells. Patients who are considered to be at risk of suffering a vitamin B12 deficiency, including older adults, should talk to their doctor about supplementing their vitamin B12 levels and should take care to avoid ingesting too much folate.Vitamin C and Iron
can be taken together as vitamin C significantly increases the absorption of non-heme iron (plant-based iron).Vitamin K
helps the blood clot properly and quickly, so people who have a vitamin K deficiency may experience difficulty getting their blood to clot properly and quickly.Multivitamins
, such as prenatal vitamins, should be taken with a snack or meal as they contain smaller doses of minerals that can interact with each other if taken together.Water-soluble vitamins, such as vitamin C and folate, should be taken on an empty stomach, while fat-soluble vitamins, such as vitamins A, E, D and K, should be taken with foods that contain fat to ensure proper absorption. It is important to remember that eating a wide variety of nutrient-rich foods will provide the vitamins and minerals your body needs to thrive. Taking dietary supplements can be beneficial for many people but it is important to understand which vitamins should not be taken together in order to avoid potential interactions with other nutrients or medical conditions. When it comes to taking vitamins with food or on an empty stomach, there are some general guidelines you should follow: fat-soluble vitamins like A, E, D and K should be taken with food containing fat; water-soluble vitamins like B12 and C should be taken on an empty stomach; multivitamins should always be taken with food; calcium and iron should not be taken together; calcium can affect the absorption of zinc and magnesium; pregnant women should avoid taking multivitamins containing vitamin A; patients at risk of suffering from a vitamin B12 deficiency should talk to their doctor about supplementing their levels; vitamin C increases the absorption of non-heme iron; and people with a vitamin K deficiency may experience difficulty getting their blood to clot properly. In conclusion, understanding which vitamins should not be taken together is essential for ensuring your dietary supplement does no more harm than good. Eating a wide variety of nutrient-rich foods will provide the vitamins and minerals your body needs to thrive but if you decide to take dietary supplements make sure you follow the guidelines outlined above.
