Iron, Zinc, and Selenium: A Comprehensive Overview

  1. Bariatric vitamins and minerals
  2. Additional vitamins and minerals for bariatrics
  3. Iron, zinc, and selenium

When it comes to bariatric vitamins and minerals, Iron, Zinc, and Selenium are three essential elements that should not be overlooked. In this comprehensive overview, we will discuss the importance of each of these three minerals, their potential benefits, and what to look for when considering supplements. Iron is an essential nutrient that helps the body produce hemoglobin, which is responsible for carrying oxygen throughout the body. It also plays a role in maintaining healthy brain function, supporting the immune system, and helping to regulate body temperature. Zinc is important for the growth and development of cells, and is also essential for healthy skin, nails, and hair.

Lastly, Selenium is an antioxidant that helps protect cells from damage and can help reduce the risk of certain diseases. By understanding the importance of these minerals and how they work together to support overall health, you can make sure your bariatric diet is well-rounded and complete.

Iron, zinc, and selenium

are essential minerals that are vital for bariatric health. Iron is important for producing red blood cells and transporting oxygen throughout the body. Zinc plays a major role in immune system health and helps with wound healing. Selenium is essential for thyroid function and metabolism.

Iron can be found in a variety of food sources, including lean meats, beans, nuts, legumes, fortified cereals, and dark leafy vegetables. Zinc can be found in oysters, red meat, poultry, beans, nuts, dairy products, and wheat germ. Selenium is found in tuna, salmon, shrimp, turkey, eggs, and Brazil nuts. Ensuring you are getting enough of these minerals is important for bariatric health and can be done by eating foods that are rich in them.

For those who have deficiencies or difficulty getting enough from dietary sources, taking supplements can help. However, it is important to always consult with a healthcare professional before taking any supplements. It is also important to be aware of possible interactions between iron, zinc, and selenium. Iron can interfere with the absorption of zinc if taken together.

It is best to take them at least two hours apart to ensure proper absorption. Taking large doses of zinc may also interfere with iron absorption. Additionally, taking too much selenium may cause a variety of side effects such as vomiting, nausea, hair loss, irritability, and fatigue. Therefore, it is important to always talk to your doctor about recommended doses of each mineral.


Zinc is an essential mineral that plays an important role in bariatric health.

It is a key component of several enzymes involved in metabolism and digestion, as well as for immunity and wound healing. Additionally, zinc helps regulate hormones and neurotransmitters, and is necessary for healthy skin, hair, and nails. The best sources of zinc include oysters, beef, crab, fortified breakfast cereals, nuts and seeds, legumes, and dairy products. The Recommended Daily Allowance (RDA) for zinc is 8-11 mg per day for adults. However, bariatric patients may need more due to malabsorption. It is important to be aware of potential interactions or side effects that can occur when taking zinc supplements.

Zinc can interfere with the absorption of other minerals such as copper or iron, so it is important to take them at least two hours apart. Additionally, high doses of zinc can cause stomach upset and nausea.


Selenium is an essential trace mineral that plays an important role in bariatric health. It is an antioxidant that helps protect cells from damage and has been linked to improved immune system functioning and cancer prevention. Selenium also helps regulate thyroid hormones and aids in the absorption of other minerals, like iron and zinc.

The best dietary sources of selenium are Brazil nuts, seafood, beef, eggs, poultry, and mushrooms. However, it is important to note that the amount of selenium in foods varies depending on the soil in which they are grown. People undergoing bariatric procedures should strive to get at least 55 mcg of selenium each day through food or supplementation. When taken in large doses, selenium can lead to toxicity and adverse side effects.

People should not take more than 400 mcg of selenium per day unless advised to do so by a doctor. Additionally, people should talk to their physician before combining selenium supplements with other medications, as it can interfere with the effectiveness of certain drugs.


Iron is an essential mineral for bariatric health and is necessary for many of the body's metabolic processes. Iron helps to form hemoglobin, a protein found in red blood cells that transports oxygen throughout the body. Iron deficiency anemia, a condition caused by low levels of iron, can lead to fatigue, weakness, and impaired cognitive function.

The best sources of iron are lean red meat, poultry, fish, shellfish, legumes, and fortified cereals. Iron is also found in some vegetables, such as spinach and kale. The daily recommended intake of iron depends on age and gender. Women should aim to get 18 milligrams per day, while men should aim for 8 milligrams.

It is important to note that too much iron can be dangerous and can lead to toxic accumulation in the body. Iron supplements should be taken with caution and only under the supervision of a doctor or registered dietitian. People with certain conditions, such as hemochromatosis or chronic kidney disease, should not take iron supplements without consulting a doctor. Iron, zinc, and selenium are essential minerals that play an important role in bariatric health. This article has discussed the benefits of these minerals, the best sources of each, and how to ensure you are getting enough of these essential nutrients.

Iron helps to maintain healthy red blood cells and is important for oxygen transport throughout the body. Zinc is involved in cell division and helps with wound healing and the immune system. Selenium is important for thyroid health, and can help reduce inflammation. It is important to ensure adequate intake of these minerals, as too much of any one of them can have detrimental health effects.

Eating a balanced diet rich in fruits, vegetables, and lean proteins is a great way to ensure adequate intake of these essential minerals.
