What is Ashwagandha?
Ashwagandha, scientifically known as Withania somnifera, is a small evergreen shrub that belongs to the nightshade family. It has been used for over 3,000 years in Indian Ayurvedic medicine, earning a reputation as one of the most revered herbs for its adaptogenic properties. Adaptogens are natural substances that help the body manage stress, making Ashwagandha a popular choice in both traditional and modern wellness practices. The root, often referred to as “Ashwagandha root” or “dunal root”, is the most commonly used part of the plant.
Ashwagandha contains a group of active compounds called withanolides, which are responsible for its health-promoting effects. These withanolides are found primarily in the root, which is often processed into an extract to enhance its potency and efficacy. As an adaptogen, Ashwagandha is believed to help the body resist physical, chemical, and biological stressors, potentially supporting longevity through better stress management and reduced risk of chronic stress-related conditions.
The Role of Ashwagandha in Modern Herbal Medicine
Ashwagandha is widely used today as a dietary supplement and is available in various forms, including capsules, powders, and tinctures. It is especially valued for its broad health benefits, which range from reducing stress and anxiety to improving cognitive function and boosting overall vitality. Products like Pure Organic Ashwagandha from Longevity Box use a standardised Ashwagandha root extract that ensures a consistent level of withanolides, ensuring better efficacy and safety. This standardisation allows users to benefit from a reliable dose, making it a safe herbal supplement choice.
How Does Ashwagandha Work?
Ashwagandha exerts its effects through multiple biological pathways, influencing both the endocrine and nervous systems. Its adaptogenic properties primarily function through the hypothalamic-pituitary-adrenal (HPA) axis, which regulates the body's stress response.
1. Regulating Stress Hormones
Ashwagandha’s most significant impact is on the body's stress hormone, cortisol. Research suggests that Ashwagandha may help reduce elevated cortisol levels, thereby calming the body's stress response. Many studies have found that ashwagandha extract significantly reduces cortisol levels, supporting the herb's potential to alleviate chronic stress and anxiety. This reduction in stress may have far-reaching effects on longevity, as prolonged stress is linked to premature ageing and various age-related diseases.
2. Balancing Thyroid Hormones
Ashwagandha has also been found to influence thyroid hormones, which are critical for regulating metabolism and energy levels. Studies show that Ashwagandha supplementation may help support thyroid function by increasing levels of thyroid hormones like T3 and T4, particularly in individuals with subclinical hypothyroidism. The herb’s ability to enhance thyroid hormone production makes it an effective natural supplement for those seeking to improve energy levels, metabolism, and overall vitality.
3. Anti-Inflammatory and Antioxidant Actions
Withanolides in Ashwagandha exhibit strong anti-inflammatory and antioxidant properties, helping to combat oxidative stress and inflammation in the body. Oxidative stress can accelerate ageing, damage cells, and contribute to chronic conditions like heart disease and diabetes. By reducing inflammation and neutralising free radicals, Ashwagandha may promote cellular health and protect against age-related decline.
Key Mechanisms of Action
- Regulation of cortisol levels: Helps manage stress, potentially reducing the risk of stress-induced health issues.
- Modulation of thyroid hormones: Supports metabolic balance and energy production.
- Anti-inflammatory and antioxidant effects: Protects against cellular damage, promoting overall longevity.
Potential Health Benefits of Ashwagandha
Ashwagandha offers a wide array of potential health benefits, ranging from stress relief to improved physical performance. Here, we explore some of the most notable benefits, supported by scientific research.
1. Reducing Stress and Anxiety
Ashwagandha is most famous for its ability to reduce stress and anxiety. Studies suggest that Ashwagandha may help improve mood, enhance mental clarity, and reduce feelings of anxiety. In a controlled trial, participants who took Ashwagandha extract reported a significant reduction in stress and anxiety compared to a placebo group. This adaptogenic herb works by regulating neurotransmitters like serotonin and dopamine, which are associated with mood and mental well-being. By improving mental health, Ashwagandha can contribute to a better quality of life and potentially extend health span.
2. Enhancing Cognitive Function
Research has shown that Ashwagandha may improve memory, attention, and information processing speed. This effect is attributed to its neuroprotective properties, which help protect brain cells from oxidative damage. In a study to evaluate the effects of Ashwagandha on cognitive function, participants who took Ashwagandha extract demonstrated improved memory and learning abilities compared to those who did not. These cognitive benefits make Ashwagandha a valuable herbal supplement for maintaining mental acuity and reducing age-related cognitive decline.
3. Supporting Physical Performance and Muscle Strength
Ashwagandha may also enhance physical performance. Research indicates that it can improve endurance, muscle strength, and recovery time. In a study involving healthy adults, participants who took Ashwagandha per day experienced improved strength and muscle growth compared to a placebo group. This effect is likely due to Ashwagandha's ability to reduce exercise-induced muscle damage and inflammation, supporting a more active lifestyle and potentially promoting a longer health span.
4. Balancing Hormones and Boosting Fertility
Ashwagandha’s influence on hormonal balance extends beyond the thyroid. It has been shown to increase testosterone levels in men, which may enhance vitality and sexual performance. A study found that Ashwagandha significantly increased testosterone levels and improved seminal plasma quality in infertile males. This benefit may also contribute to overall well-being and vitality, supporting healthy ageing.
5. Promoting Better Sleep
Ashwagandha’s calming effects may extend to better sleep quality. The herb has been found to enhance sleep by regulating GABA receptors, which play a role in calming the nervous system. An adjunctive study of an Ashwagandha extract found that participants experienced improved sleep quality, with reduced instances of waking during the night. Better sleep quality is linked to a stronger immune system, better mental health, and improved longevity.
6. Protecting Liver Health
Some evidence suggests that Ashwagandha may protect against liver injury by reducing liver inflammation and oxidative stress. The herb’s antioxidant properties can help detoxify the liver, promoting better overall health and potentially extending the body's ability to process toxins efficiently as it ages.
Summary of Potential Health Benefits
- Reduces stress and anxiety: Improves mood and overall mental well-being.
- Enhances cognitive function: Improves memory, focus, and information processing.
- Supports physical performance: Increases strength, endurance, and recovery.
- Balances hormones: Improves thyroid function and testosterone levels.
- Improves sleep quality: Enhances sleep by calming the nervous system.
- Protects liver health: Reduces inflammation and supports detoxification.
By reducing stress, enhancing mental and physical health, and protecting the body from damage, Ashwagandha may be a vital tool for supporting longevity. It not only helps manage current health concerns but may also contribute to a longer, healthier life.
Potential Risks and Side Effects of Ashwagandha
While Ashwagandha is generally considered safe to use, it is important to be aware of potential risks and side effects. This section explores the safety of Ashwagandha root extract, including studies that evaluate its use, dosage, and long-term effects.
Common Side Effects
Ashwagandha supplements are well-tolerated by most users when taken in recommended doses. However, some individuals might experience mild side effects such as stomach upset, diarrhoea, or drowsiness.
