Ashwagandha and Thyroid: Natural Support Explained

Ashwagandha and thyroid health have become a popular topic of discussion among those seeking natural ways to improve their endocrine system function. This ancient medicinal herb, scientifically known as Withania somnifera, has been used for centuries in traditional medicine to address various health conditions.

In this article, we will explore the relationship between ashwagandha and thyroid health in various disorders and we’ll provide guidance on incorporating ashwagandha into your routine to support your journey towards improved thyroid health. 

Understanding Thyroid Disorders

Thyroid disorders can cause various symptoms like weight gain, fatigue, constipation, goiters, and dry skin. These conditions are typically treated with synthetic medications like levothyroxine or methimazole, but some individuals may seek natural alternatives to improve their thyroid health. Two common types of thyroid disorders:

Hypothyroidism (Underactive Thyroid)

A deficiency of thyroid hormones, resulting from the underactive functioning of the thyroid gland, is known as hypothyroidism. This can lead to a variety of symptoms including fatigue, weight gain, depression, and muscle weakness. Some common causes of hypothyroidism include Hashimoto’s disease (an autoimmune disorder), iodine deficiency, and certain medications.

Hyperthyroidism (Overactive Thyroid)

In contrast to hypothyroidism, hyperthyroidism occurs when the thyroid gland produces too much hormone leading to an overstimulation of metabolism resulting in symptoms such as rapid heart rate, anxiety, irritability, tremors, excessive sweating, and heat intolerance among others. Graves’ disease, toxic multinodular goiter, subacute viral infection all contribute towards the development of this condition.

If you’re looking for alternative ways to manage your thyroid health without relying solely on medication, it might be worth considering natural supplements like ashwagandha root extract (Withania somnifera). 

Ashwagandha’s Impact on Hypothyroidism

Recent studies have shown that ashwagandha root extract (Withania somnifera) might be beneficial for those suffering from hypothyroidism. In a study involving 50 people with hypothyroidism, participants who took 600 mg of ashwagandha daily experienced significant improvements in their T3 and T4 hormone levels compared to those taking a placebo.

Cortisol-lowering effects of ashwagandha

Ashwagandha is known for its ability to lower cortisol levels in the body. By reducing cortisol levels, ashwagandha may help counteract the suppression of thyroid-stimulating hormones (TSH) caused by elevated cortisol. By reducing cortisol levels, ashwagandha may help improve thyroid function and alleviate symptoms associated with hypothyroidism such as fatigue, weight gain, and depression. A study published in the Indian Journal of Psychological Medicine found that individuals who took ashwagandha supplements had significantly reduced cortisol levels compared to those who received a placebo.

Stimulating the endocrine system

In addition to its cortisol-lowering properties, ashwagandha has been found to stimulate the endocrine system which plays an essential role in regulating hormonal balance within our bodies including thyroid hormones like TSH, T3, and T4, making it a potentially useful natural remedy for managing underactive thyroids. It’s believed that ashwagandha works by increasing the production of these hormones, which in turn helps to improve overall thyroid function.

  • Tip: To experience the potential benefits of ashwagandha for hypothyroidism, consider taking a daily supplement containing at least 500 mg of ashwagandha root extract. Advise your doctor before beginning any supplement regimen.

Ashwagandha’s influence on hypothyroidism is yet to be explored, however its cortisol-reducing properties and endocrine system stimulation could prove advantageous. Few studies have been conducted to explore the effects of ashwagandha on bipolar disorder; more investigations are necessary to decide its effectiveness in this region.

Limited Research on Bipolar Disorder and Ashwagandha

Although there is limited research available, some studies have explored the potential benefits of ashwagandha for individuals with bipolar disorder. One such eight-week study conducted on adults with bipolar disorder showed that three participants experienced increased T4 levels after being given ashwagandha supplements. This suggests a possible positive impact on thyroid function in these patients.

The study’s small sample size, however, restricts the validity of its conclusions. Although the focus of this study was not specifically on hypothyroidism, its results may have implications for cognitive functioning in those with bipolar disorder and potential benefits for managing hypothyroidism. Thus, to determine any potential effects of ashwagandha supplementation on hypothyroidism, further investigation is needed.

  • Potential Benefits: The increase in T4 levels observed in some participants may indicate a potential benefit for those struggling with hypothyroidism as part of their bipolar disorder treatment plan.
  • Limited Sample Size: Due to the small number of participants involved in this study and its primary focus not being solely thyroid health, further research is necessary to confirm any findings related to ashwagandha’s effect on thyroid hormone levels.
  • Future Studies: More extensive clinical trials are required to determine whether or not ashwagandha could serve as an effective natural supplement for managing both hypothyroidism and other symptoms associated with bipolar disorder.

In conclusion, while there is some evidence to suggest that ashwagandha may improve thyroid health in individuals with bipolar disorder, more research is needed to confirm these findings. As with any supplement, it’s essential to speak with a healthcare provider before taking ashwagandha or any other supplement to ensure it is safe and appropriate for your specific health conditions and needs.

Potential Risks for Hyperthyroid Patients

While there have been no human studies examining the relationship between ashwagandha supplementation and hyperthyroidism, it is believed that by increasing both T3 and T4 hormone production, ashwagandha may exacerbate symptoms. This could potentially lead to thyrotoxicosis, which if left untreated can result in heart failure, weight loss, extreme thirst, skin issues, among other complications. Therefore, it is essential for individuals with hyperthyroidism to speak to their medical provider prior to consuming ashwagandha supplements.

  • Heart Failure: Excessive thyroid hormones can cause an increased heart rate and blood pressure leading to a higher risk of developing heart problems or worsening existing conditions.
  • Weight Loss: Hyperthyroid patients often experience unintended weight loss due to an overactive metabolism caused by excessive thyroid hormones.
  • Skin Issues: Thyrotoxicosis can lead to various skin problems such as hives or itching as well as hair thinning or brittle nails.

In addition to these potential risks associated with using ashwagandha for hyperthyroid patients, there are also concerns about possible interactions with medications used in treating this condition. For example:

  1. Ashwagandha might interfere with antithyroid drugs like methimazole (Tapazole) and propylthiouracil (PTU), reducing their effectiveness in controlling thyroid hormone levels.
  2. The supplement could also interact negatively with beta-blockers prescribed for managing symptoms of hyperthyroidism, such as propranolol (Inderal) or atenolol (Tenormin).

Given these potential risks and interactions, it is crucial for hyperthyroid patients to discuss their interest in ashwagandha with a healthcare professional before incorporating the supplement into their routine. This will ensure that they receive proper guidance on whether ashwagandha is suitable for them and how best to use it without compromising their health.

Hyperthyroid sufferers ought to be mindful of the potential hazards related with ashwagandha, and take necessary steps to guarantee their wellbeing. However, it is important to note that ashwagandha can still provide numerous benefits when taken in moderation; therefore, understanding the safety considerations and precautions for pregnant women or those with autoimmune diseases is essential.
