Ashwagandha for Anxiety: Scientific Evidence and Optimal Use

What is Ashwagandha? An Adaptogen by Nature

Ashwagandha, whose scientific name is Withania somnifera, is a medicinal herb revered in Ayurvedic medicine, India's ancient healing science, for thousands of years. It is classified as an adaptogen, a unique category of plants that help the body resist the effects of physical and mental stress, promoting homeostasis and internal balance. Its name, "Ashwagandha," translates from Sanskrit as "smell of horse," alluding both to its particular aroma and to the belief that it imparts the strength and vitality of a horse.

At Kóre Labs, our fascination with Ashwagandha lies in its ability to offer comprehensive support for well-being, in line with our philosophy of "Science First" and "Quality or Nothing." For a deeper dive into the world of adaptogens, we invite you to read our article: Adaptogens: Extraction, active components, and mechanisms of action.

Mechanism of Action: How Does Ashwagandha Combat Anxiety?

Ashwagandha's ability to mitigate anxiety is not mere conjecture; it is rooted in complex biochemical mechanisms that directly impact the central nervous system and the HPA (hypothalamic-pituitary-adrenal) axis, the body's primary stress response pathway.

HPA Axis Modulation

Chronic stress activates the HPA axis, leading to the excessive release of cortisol, the stress hormone. Ashwagandha intervenes in this process, helping to normalize cortisol levels and reduce HPA axis hyperactivity. This translates into a reduced feeling of stress and anxiety.

Impact on Neurotransmitters

The main bioactive components of Ashwagandha, known as withanolides, interact with several key neurotransmitters in the brain:

• GABA (Gamma-Aminobutyric Acid): Ashwagandha can enhance GABAergic activity, the brain's main inhibitory neurotransmitter. By increasing GABA activity, neuronal excitability is reduced, promoting calm and relaxation.
• Serotonin: Although more research is needed, some studies suggest that Ashwagandha could influence serotonin levels, a crucial neurotransmitter for mood and well-being.

Antioxidant and Anti-inflammatory Properties

Chronic stress and anxiety can generate oxidative stress and inflammation in the brain. Ashwagandha's withanolides possess potent antioxidant and anti-inflammatory properties that protect brain cells from damage, contributing to healthier brain function and greater resilience to stress.

Ashwagandha and Anxiety: Irrefutable Scientific Evidence

At Kóre Labs, our "Science First" philosophy drives us to base our recommendations on the most solid clinical evidence. Multiple studies have investigated the effectiveness of Ashwagandha in reducing symptoms of anxiety and stress:

• A pivotal, double-blind, placebo-controlled study found that a high-concentration full-spectrum Ashwagandha root extract significantly reduced cortisol levels and improved scores on stress and anxiety scales in adults (1).
• Another systematic review and meta-analysis concluded that Ashwagandha can be a safe and effective intervention for improving stress and anxiety in adults (2).
• A more recent clinical study highlighted the adaptogenic and anxiolytic effects of Ashwagandha root extract in healthy adults, observing improvements in perceived stress levels and overall well-being (3).

These findings reinforce Ashwagandha's position as a first-line adaptogen for those seeking natural support for their mental health. For more details on how we select and validate our ingredients, see our article: Kore Lab: Science, Adaptogens, and High-Level Human Performance.

Beyond Anxiety: Additional Benefits of Ashwagandha

Although its impact on anxiety is remarkable, Ashwagandha is an adaptogen with a spectrum of benefits that go beyond stress management, contributing to a holistic rebirth of your well-being:

• Improved Sleep: By reducing stress and promoting relaxation, Ashwagandha can improve sleep quality, helping you fall asleep more easily and enjoy more restorative rest.
• Hormonal Balance: Contributes to the balance of various hormones, including thyroid and sex hormones, which can have a positive impact on overall well-being and energy.
• Physical Performance: Some studies suggest it can improve muscle strength and endurance, making it a valuable supplement for athletes and active individuals.
• Cognitive Function: Although less studied than its anxiolytic effect, Ashwagandha shows potential to improve memory and cognitive function, especially in stressful situations.

These additional benefits consolidate Ashwagandha as a versatile functional supplement, ideal for those looking to optimize their health on multiple fronts.

Dosage and Optimal Use of Ashwagandha for Anxiety

Determining the correct dosage of Ashwagandha is crucial to maximizing its benefits and ensuring its safety. The optimal dose may vary depending on the extract concentration and the condition being treated. In general, most studies demonstrating efficacy in reducing anxiety use doses of:

• Standardized extracts (with 2.5% to 5% withanolides): Between 300 mg and 600 mg per day, divided into two doses.
• Powdered root: Higher doses, from 1 to 3 grams per day, also divided.

It is important to note that Ashwagandha usually requires continuous use to observe its full effects. Benefits for anxiety and stress generally manifest after several weeks of consistent supplementation. It is always recommended to consult with a healthcare professional before starting any supplement, especially if you have pre-existing medical conditions or are taking other medications.
