The thyroid gland sits at the front of the throat and is shaped like a large butterfly. A healthy thyroid plays an important role in energy, mood, metabolism and overall well-being through the production of the hormone thyroxin. This hormone requires manganese, iodine, selenium, vitamins and minerals for its production. The thyroid also controls the rate at which the body uses energy, causing fluctuation in body weight. Along with healthy, balanced eating habits, certain supplements including EFA’s have been shown to balance and improve thyroid function as well as overall health. Low levels of the amino acid l-tyrosine and (available in green food Green Magic & Ultra Whey Pro Protein) may contribute to low thyroid function resulting in low energy, low mood and weight gain. Sufficient levels of B12 are necessary for the thyroid to utilize the hormones it produces; otherwise thyroid hormones float around in the bloodstream unused.
