Millions of Americans are diagnosed with some type of thyroid disease each year. Some supplements, like vitamin C, can help improve thyroid function, which is essential for overall health.
According to Progressive Health, vitamin C is an antioxidant vitamin that can improve thyroid function by minimizing the stress from free radicals and harmful toxins. They site summarizes a study published in the Journal of Thyroid Research in which rats were exposed to two common environmental toxins that are known to decrease the thyroid’s function. Some of the rats were exposed to the toxins and also given supplemental vitamin C, and these rats were able to maintain healthy thyroid function.

Natural Health 365 notes many studies have confirmed a link between oxidative stress from toxins and free radicals and decreased thyroid function or hypothyroidism. They cite a study published in the BMC Endocrine Disorders journal that found all study subjects with low thyroid function were also deficient in the antioxidants selenium, zinc, and vitamin C.
Patients with more severe hypothyroidism are often managed medically with synthetic hormones like levothyroxine that mimic what the thyroid gland is unable to produce in adequate quantities. Even with hormone therapy, some patients continue to experience symptoms like fatigue, depression, and weight gain, says Natural Health 365, suggesting the medication may not be working properly.

According to Endocrine Society, supplemental vitamin C improves the body’s absorption of levothyroxine. This can decrease the need for an increased dose of the drug.
People who suspect they may have an underactive thyroid gland should consult with their physician and ask about taking a vitamin C supplement before resorting to medical intervention. Additionally, patients who are already on synthetic hormone treatment for hypothyroidism and are still experiencing symptoms may want to consider vitamin C therapy to help boost the effectiveness of the medication.
