Thyroid Complex by Rise-N-Shine is specially formulated with a unique combination of vitamins, minerals, herbs, and amino acids to help support normal thyroid activity. A thyroid that functions well, can help to maintain many body functions, including weight, metabolism, and the body's energy reserves. Hypothyroidism and underactive thyroids can cause feelings of sluggishness and difficulties in maintaining a healthy weight. Hyperthyroidism or an overactive thyroid may also elevate a person's anxiety levels. Rise-N-Shine's Thyroid Complex contains Vitamin B12, Iodine, Zinc, Selenium, Ashwagandha Root, and more. Iodine is essential for thyroid function.
