What is Ashwagandha and How Does It Work?
Ashwagandha, also known as "Indian ginseng" or Withania somnifera, is a fundamental herb in Ayurvedic medicine, used for thousands of years for its restorative and adaptogenic properties. Adaptogens are natural substances that help the body adapt to physical, chemical, or biological stress, promoting homeostasis.
The main active compounds in Ashwagandha are withanolides, natural steroids believed to be responsible for most of its pharmacological effects. These compounds interact with the nervous system, the immune system, and the endocrine system, which explains their wide spectrum of benefits. Among them, the following stand out:
- Reduction of stress and anxiety: It acts by modulating the hypothalamic-pituitary-adrenal (HPA) axis, the body's primary stress response system.
- Improved sleep: Helps induce more restorative sleep.
- Support for cognitive function: Contributes to memory and focus.
- Anti-inflammatory and antioxidant properties: Protects cells from oxidative damage.

Ashwagandha and Thyroid Function: The Scientific Evidence
The relationship between Ashwagandha and the thyroid has been the subject of several studies, with promising results, especially in the context of subclinical hypothyroidism. It is crucial to understand that science supports a supportive role, not a substitution for medical treatments.
Ashwagandha in Subclinical Hypothyroidism
Subclinical hypothyroidism (SCH) is characterized by elevated TSH (thyroid-stimulating hormone) levels but with normal levels of free T3 (triiodothyronine) and T4 (thyroxine) thyroid hormones. Although often asymptomatic, it can progress to clinical hypothyroidism and is associated with an increased risk of cardiovascular disease and cognitive dysfunction.
Several clinical studies have investigated the effect of Ashwagandha in patients with SCH:
- Sharma et al. (2018) Study [1]: A double-blind, randomized, placebo-controlled trial evaluated the efficacy and safety of Ashwagandha root extract in patients with SCH. The results showed that the group receiving Ashwagandha experienced a significant improvement in TSH, T3, and T4 levels compared to the placebo group. This suggests that Ashwagandha could normalize thyroid function in individuals with SCH.
- Gannon et al. (2014) Study [2]: Another similar investigation found that a standardized Ashwagandha extract improved thyroid parameters in patients with SCH, demonstrating a reduction in TSH and an increase in T3 and T4, indicating a positive effect on thyroid hormone conversion.
These findings are encouraging and suggest that Ashwagandha could be a complementary option for managing subclinical hypothyroidism, always under the supervision of a healthcare professional.
Proposed Mechanisms of Action
How might Ashwagandha influence thyroid function? Several mechanisms are proposed:
- Stress Reduction and HPA Axis Modulation: Chronic stress can negatively impact thyroid function by altering communication between the hypothalamus, pituitary, and thyroid. Ashwagandha, as an adaptogen, helps regulate cortisol and the HPA axis, which could alleviate stress-induced thyroid function suppression [3].
- Antioxidant Properties: Oxidative stress can damage thyroid cells. The withanolides in Ashwagandha possess potent antioxidant properties, protecting the thyroid gland from cellular damage and improving its function [4].
- Direct Effect on Hormonal Conversion: Some studies suggest that Ashwagandha could directly influence the conversion of T4 (the inactive form) to T3 (the active form) in the body, which is crucial for the effectiveness of thyroid hormones.
Ashwagandha, Hyperthyroidism, and Autoimmune Diseases
While the evidence for subclinical hypothyroidism is promising, it is essential to be cautious in other scenarios:
- Hyperthyroidism: In cases of hyperthyroidism (excessive thyroid hormone levels), Ashwagandha could exacerbate the condition by further increasing T4 production. Therefore, it is contraindicated in people with hyperthyroidism.
- Autoimmune Thyroid Diseases (such as Hashimoto's Thyroiditis): Although Ashwagandha has immunomodulatory and anti-inflammatory properties that could be beneficial, its effect on the immune system is complex. In autoimmune diseases, where the immune system attacks the body's own tissues, Ashwagandha could, theoretically, stimulate the immune response and potentially worsen the condition in some individuals. The evidence is limited, and much more research is needed. A specialist should always be consulted before considering its use.
Optimal Dosage and Use of Ashwagandha for Thyroid
While there is no universally established dose for thyroid support, studies that have shown benefits in subclinical hypothyroidism have used Ashwagandha root extract doses ranging from 300 mg to 600 mg per day, standardized to contain a specific percentage of withanolides (generally 2.5% to 5%).
At Kóre Labs, our Ashwagandha is formulated under the principle of "Science First" and "Quality or Nothing." This means we select high-purity and potent extracts, with precise standardization to ensure the concentration of withanolides, guaranteeing the efficacy and safety you expect from a premium product.
General recommendations:
- Medical Consultation: Always consult your doctor or endocrinologist before starting any supplement, especially if you have a pre-existing thyroid condition or are taking medication.
- Monitoring: If your doctor approves the use of Ashwagandha, it is crucial to monitor your thyroid hormone levels (TSH, T3, T4) regularly to adjust medication dosage if necessary and ensure no adverse effects.
- Supplement Quality: Always opt for high-quality, standardized Ashwagandha supplements with purity certifications, such as those offered by Kóre Labs.
Important Considerations and Precautions
Despite its potential benefits, Ashwagandha is not without precautions, especially concerning thyroid health:
- Interactions with Thyroid Medications: Ashwagandha can interact with thyroid medications, such as levothyroxine. If you take these medications, Ashwagandha could potentiate their effects, potentially leading to medication-induced hyperthyroidism. It is imperative that any adjustment in medication or the addition of supplements be done under strict medical supervision.
- Pregnancy and Breastfeeding: It is recommended to avoid the use of Ashwagandha during pregnancy and breastfeeding due to the lack of sufficient studies on its safety in these populations.
- Surgery: Ashwagandha may have sedative effects and could interact with anesthesia. It is recommended to discontinue its use at least two weeks before any scheduled surgery.
- Pre-existing Medical Conditions: People with autoimmune diseases (beyond the thyroid), diabetes, or blood pressure problems should consult their doctor before using Ashwagandha.
