The thyroid gland, an often overlooked yet pivotal part of our endocrine system, plays a vital role in regulating metabolism and maintaining overall wellness.

With thyroid disorders becoming increasingly prevalent, understanding and exploring natural alternatives for thyroid support is imperative. In this blog, we will delve into the enigmatic relationship between Ashwagandha and the thyroid.

In this intricate dance of hormones and cellular activity, Ashwagandha steps in with grace and potency. Scientific studies have begun to unveil its remarkable ability to modulate thyroid hormone levels, offering relief and restoration where it’s needed most. Whether it’s revving up hormone production in cases of an underactive thyroid or instilling calm in instances of an overactive one, Ashwagandha’s adaptogenic nature ensures it responds to the body’s specific needs.

Ashwagandha for thyroid

We’ll uncover the historical significance of Ashwagandha, understand the essentials of thyroid function, and review key research findings on how Ashwagandha can impact thyroid health.

What is Ashwagandha?

Ashwagandha, botanically known as Withania somnifera, is a small shrub native to India and parts of North Africa. The plant’s roots and berries have been utilized for over 3,000 years, primarily in Ayurveda, which is a traditional Indian system of medicine. In Sanskrit, ‘Ashwa’ means horse and ‘gandha’ means smell – the name is derived from the unique smell of its roots, which is said to be similar to that of a horse. It is also sometimes referred to as ‘Indian ginseng’ or ‘winter cherry’.

Fast forward to the present day, and Ashwagandha’s reputation has crossed borders. It is celebrated in the Western world as an adaptogen, a natural substance considered to help the body adapt to stress and to exert a normalizing effect upon bodily processes. Health enthusiasts incorporate Ashwagandha in various forms including as a powder, which can be added to smoothies or teas, capsules for ease of dosage, or even as tinctures and extracts. Moreover, Ashwagandha is often a common ingredient in many herbal formulations and supplements aimed at promoting general wellness.

Understanding the Thyroid Gland

Before delving into how Ashwagandha can affect the thyroid, it’s essential to have a fundamental understanding of the thyroid gland itself. The thyroid is a small, butterfly-shaped gland located at the base of the neck, just below the Adam’s apple. It’s part of the endocrine system, which is a collection of glands that produce and regulate hormones in the body.

Role of the Thyroid in Metabolism and Overall Health:

The thyroid gland plays a critical role in the body’s metabolism by producing two main hormones: triiodothyronine (T3) and thyroxine (T4). These hormones affect nearly every cell in your body and are crucial for regulating a wide range of physiological activities. These include:

Energy Production: T3 and T4 help to regulate the body’s energy production and consumption, ensuring that the body has enough energy for its needs.

Body Temperature: They help in regulating body temperature, contributing to the maintenance of a stable internal environment.

Weight Management: These hormones influence the rate at which calories are burned and thus have a role in weight maintenance.

Heart Function: The thyroid hormones are also essential in the proper functioning of the heart, affecting heart rate and blood flow.


Common Thyroid Disorders:

When the thyroid doesn’t function properly, it can lead to a range of health problems. The two most common thyroid disorders are:

Hypothyroidism: This occurs when the thyroid is underactive and does not produce enough thyroid hormones. Symptoms of hypothyroidism include fatigue, weight gain, cold intolerance, and depression.

Hyperthyroidism: This is the opposite of hypothyroidism and occurs when the thyroid is overactive, producing too much thyroid hormone. Symptoms of hyperthyroidism include weight loss, heat intolerance, anxiety, and a rapid heart rate.


There are various causes for these disorders, including autoimmune diseases (such as Hashimoto’s thyroiditis and Graves’ disease), iodine deficiencies, or even certain medications.

Why it Matters

Understanding the fundamental role that the thyroid gland plays in our health underscores the importance of maintaining its proper function. With the prevalence of thyroid disorders and the consequential impact on quality of life, exploring avenues for support and management is crucial.

In-depth Look at a Prominent Study

One of the key studies that have significantly contributed to the understanding of Ashwagandha’s potential impact on thyroid function is a pilot study conducted in 2016 . This study specifically explored the efficacy and safety of Ashwagandha in the treatment of subclinical hypothyroidism (SCH), which is a precursor to overt hypothyroidism.

Understanding Subclinical Hypothyroidism:

Subclinical hypothyroidism is characterized by elevated levels of thyroid-stimulating hormone (TSH) but normal levels of thyroxine (T4). It can affect up to 8% of the population. If left untreated, SCH can progress to full-blown hypothyroidism and may worsen other conditions such as type 2 diabetes, cardiovascular disease, and neuromuscular disorders.

Study Design:

Ashwagandha, known for its adaptogenic properties and historical use in managing hormonal imbalances, was put to the test in this double-blind, placebo-controlled study. Fifty patients aged between 18 to 50 years, with TSH levels ranging from 4.5 to 10.0 µIU/L and normal T3 and T4 levels, were enrolled. They were divided into two groups: one group received 600 mg of Ashwagandha root extract (KSM-66®) daily, while the other received a placebo, for a duration of eight weeks.

Findings and Significance:

The results of the study were promising. Participants who received Ashwagandha experienced significant increases in T3 levels at both 4 and 8 weeks compared to the placebo group. Specifically, serum T3 levels increased by 18.6% at 4 weeks and 41.5% at 8 weeks in the Ashwagandha group. Moreover, T4 levels also showed significant increases, and TSH levels decreased in the Ashwagandha group compared to the placebo group. Importantly, there were no significant changes in physical, hematologic, or vital parameters, and any adverse events reported were mild and temporary.

Conclusions and Limitations:

The authors concluded that Ashwagandha root extract appears to safely normalize thyroid indices in patients with SCH, possibly by influencing the hypothalamic-pituitary-thyroid axis. However, it’s important to note that the authors emphasized the need for larger trials with longer durations to solidify these findings and assess long-term safety. Additionally, one limitation of this study was the lack of screening for anti-thyroid antibodies, which could be indicative of Hashimoto’s thyroiditis.

This study represents a critical step in understanding the potential role of Ashwagandha in supporting thyroid health, especially for those with subclinical hypothyroidism. However, further research is required to fully establish its efficacy and safety profiles.

Role of Lifestyle and Diet in Thyroid Health

As we explore the potential benefits of Ashwagandha in supporting thyroid function, it is imperative to understand that thyroid health is multifaceted and influenced by various factors including lifestyle and diet. A balanced diet rich in nutrients, particularly iodine, selenium, and zinc, can be beneficial for thyroid health. Moreover, managing stress through mindfulness, exercise, and adequate sleep can positively affect the thyroid.

Ashwagandha, with its adaptogenic properties, can be a component of a holistic approach to managing thyroid health. When used in conjunction with a balanced diet and lifestyle modifications, it might enhance the body’s ability to maintain thyroid hormone balance.


The Importance of a Balanced Approach:

Relying solely on supplementation is not a silver bullet for thyroid disorders. It’s crucial to have a comprehensive approach that includes monitoring, lifestyle changes, dietary considerations, and consulting healthcare professionals for personalized advice.

We embarked on a journey to unravel the enigmatic relationship between Ashwagandha and the thyroid. From understanding the historical significance of Ashwagandha and the fundamentals of thyroid function to examining intriguing research findings, it’s clear that Ashwagandha holds potential in supporting thyroid health. However, it is important to approach this with caution and mindfulness. Research, though promising, is still in the nascent stages, and larger studies are required to ascertain the long-term efficacy and safety of Ashwagandha for thyroid support.

It’s also vital to recognize the importance of a balanced and holistic approach, which includes a combination of lifestyle, dietary practices, and consultation with healthcare professionals. In an age where thyroid disorders are on the rise, staying informed and exploring various avenues for support and management is the key to promoting thyroid health and overall well-being.
