Ashwagandha (Withania somnifera), also known as Indian ginseng, is a medicinal plant from traditional Indian medicine, specifically Ayurvedic medicine. It has long been recognized for its adaptogenic properties, meaning its ability to strengthen the body's resistance to stress, but what is its real impact on thyroid function?
Ashwagandha and its effect on the thyroid
Ashwagandha primarily acts on the regulation of the nervous system and on the management of the response to stress, essential factors for the proper functioning of the thyroid gland. The latter produces thyroid hormones T3 and T4, responsible for regulating many bodily functions such as metabolism, body temperature, growth, and weight management.
In cases of chronic stress, thyroid function can be impaired, leading to disorders such as hypothyroidism (characterized by insufficient production of thyroid hormones and often accompanied by weight gain) or, conversely, hyperthyroidism, which can lead to excessive weight loss.
Ashwagandha in cases of hypothyroidism
Some research published in the Journal of Alternative and Complementary Medicine has shown that ashwagandha can improve thyroid function, particularly in cases of mild hypothyroidism, by promoting the production of thyroid hormones (T3 and T4). This could help people suffering from symptoms such as chronic fatigue, cold sensitivity, slowed metabolism, and difficulty losing weight.
Ashwagandha and hyperthyroidism: necessary precaution
In cases of hyperthyroidism, characterized by excessive production of thyroid hormones, taking ashwagandha must be carefully monitored. Since the plant can further stimulate the thyroid, there is a risk of aggravating symptoms of thyroid overactivity, such as rapid weight loss, increased nervousness, and heart palpitations. Therefore, medical advice is essential before any intake.
Recommendations and precautions for use
Although ashwagandha is traditionally used for its multiple benefits and adaptogenic properties, it does not replace appropriate medical treatment in cases of thyroid disorders. It is essential to consult your healthcare professional before incorporating this type of supplement into your routine, especially if you are already on medication.
In conclusion, ashwagandha can be beneficial in certain situations to support thyroid function, particularly in cases of mild hypothyroidism associated with stress. However, medical supervision is imperative to correctly adjust dosages and avoid any interactions or side effects.
