Iodine is the main nutrient associated with a hormone produced in the thyroid. This hormone is responsible for monitoring heartbeat and correcting where needed, the reproduction of skin cells, brain wellness and regulating body temperature. Iodine is found in cheese, milk, eggs, soy milk, and salt that contains iodine. A lack of iodine may decrease the hormone’s ability to function properly and complete the functions by the hormone. 

Vitamin B12:

Vitamin B12 is regarded as the most vital nutrient, as it is responsible for producing red blood cells, maintaining our nervous system, and DNA. Vitamin B12 can be found in foods that include seafood, eggs, and various dairy products. A lack of vitamin B12 can lead to megaloblastic anemia. 

Omega 3: 

Omega 3 is an essential fat that the body needs. Omega 3 is responsible for brain and heart health and has been shown to reduce the risk of depression. One study even suggests that Omega 3 is vital to eye health, as it prevents damage to the retina. Omega 3 can be found in various types of seafood, nuts including walnuts and flax seeds, and certain oils including canola and soybean oil. A lack of Omega 3 can lead to certain skin conditions including dermatitis.

Magnesium is required to reproduce protein, metabolize food into energy, and regulate the nervous system. Magnesium can be found in various leafy greens including spinach, avocados, black beans, and nuts. A lack of magnesium can lead to muscle spasms and tremors, more headaches, and weaker bones.
