What Are The Health Benefits of Ashwagandha?
1. Reduces symptoms of stress and anxiety
Ashwagandha is clinically proven to alleviate stress and reduce symptoms of anxiety. According to multiple research studies, ashwagandha significantly lowers levels of the stress hormone cortisol. By lowering cortisol, ashwagandha reduces the physical symptoms associated with stress and anxiety while ameliorating some of the negative health consequences of chronically raised cortisol levels.
One study found that after 60 days of supplementing with Ashwagandha, participants in the treatment group had a remarkable 27.9% decrease in cortisol compared to baseline levels. These results demonstrate some of the impressive stress-relieving benefits of ashwagandha [1]. Evidence that ashwagandha lowers cortisol levels has been shown time after time in multiple human trials over recent years. [2] [3] [4]
The administration of ashwagandha also significantly reduces anxiety scores on the Hamilton Anxiety Rating Scale (HAM-A). This test is a widely used and well-validated tool for assessing the severity of anxiety by examining the number and severity of physiological and psychological symptoms experienced by participants.
For example, a randomized, double-blind, placebo-controlled trial found that over the course of a 60-day intervention, study participants receiving an extract of ashwagandha had a 41% decrease in their HAM-A scores, demonstrating a significant improvement in anxiety compared to the placebo group. [5]

2. Improves low thyroid function
Studies have shown that ashwagandha supports thyroid health by regulating thyroid hormone levels in individuals experiencing low/underactive thyroid function, also known as hypothyroidism. Treatment with ashwagandha root may also reduce inflammation and provide antioxidant effects, which could further protect the thyroid gland and support overall wellness.
For example, a study focused on individuals with hypothyroidism found that taking 600 mg of ashwagandha root extract daily for eight weeks led to significant increases in essential thyroid hormones T3 and T4 compared to those taking a placebo. [6]
In an animal study of hypothyroid rats, ashwagandha was able to increase levels of T3 and T4 while reducing thyroid-stimulating hormone (TSH) levels, which are usually elevated in hypothyroidism.
Since ashwagandha raises levels of T3 and T4, it should be avoided in individuals with an overactive thyroid (hyperthyroidism), a condition in which the thyroid gland produces too many thyroid hormones.

3. Improves sleep duration & sleep quality
Ashwagandha has beneficial effects on sleep quality and sleep duration by calming the central nervous system and lowering cortisol levels. This means ashwagandha can provide relief for individuals struggling with insomnia.
A meta-analysis of randomized controlled trials found that ashwagandha supplementation significantly improved overall sleep, which was demonstrated using measurements like:
- Sleep onset latency (the amount of time it takes to fall asleep)
- Total sleep time
- Wake time
- Total time in bed
- Sleep efficiency
[7]

4. Enhances sperm health and male fertility
Ashwagandha supports male fertility by enhancing sperm health and sexual function. Ashwagandha's benefits for fertility have been known for thousands of years in Ayurvedic medicine, and now modern research is finally catching up to explain its ability to improve reproductive health.
Researchers have studied men with low sperm count (known as oligospermic males) who were randomized to either receive ashwagandha in the form of a full spectrum root extract for 90 days or a placebo for the same period.
At the end of the study, a semen analysis found that men taking the ashwagandha root supplement had a 167% increase in sperm count, a 53% increase in semen volume, and a 57% increase in sperm motility. These results demonstrate a truly impressive improvement in overall semen quality after taking ashwagandha. [8]

5. Increases testosterone levels in men
On average, ashwagandha naturally boosts testosterone by 17% in men, according to high-quality research. Testosterone is a sex hormone that plays a vital role in regulating muscle mass and strength, sperm health, sexual function, and body composition. [9]
The main mechanism through which ashwagandha appears to elevate testosterone levels is by lowering the stress hormone cortisol, which interferes with the normal function of the testes. This means that when cortisol levels are high, it can lead to reduced testosterone production. [10]
Ashwagandha’s scientifically proven benefits on sleep may be another mechanism by which it improves testosterone levels since just one week of reduced sleep time in men lowered daytime testosterone levels by a whopping 10-15%. [11]
6. Enhances focus & cognitive function
Ashwagandha supports cognitive function over time by reducing inflammation and oxidative stress in the brain. By reducing stress levels, ashwagandha also indirectly improves concentration and mental clarity. Additionally, it may increase the production of brain-derived neurotrophic factor (BDNF), a protein that helps in the growth and development of nerve cells.
For example, a randomized, double-blind, placebo-controlled trial found that when stressed healthy adults took an ashwagandha supplement (Withania Somnifera root extract) for 90 days, they experienced enhanced focus, memory, mental well-being and reduced stress levels compared to the placebo! [12]
7. Increases physical performance & muscle health
Ashwagandha can improve physical performance in several ways by:
- Enhancing muscle strength, growth, and endurance
- Reducing exercise-induced muscle damage
- Increasing oxygen capacity
It’s thought that ashwagandha's effects on muscle strength and performance may be attributed to its ability to increase testosterone levels.
A randomized controlled trial published in the Journal of the International Society of Sports Nutrition examined the effects of ashwagandha supplementation on muscle strength in healthy young men. The study found that participants who took ashwagandha extract for 8 weeks experienced significant improvements in muscle strength compared to the placebo group. [14]
Another study published in the Journal of Ayurveda and Integrative Medicine also reported similar findings, showing that ashwagandha supplementation led to significant improvements in muscle strength and muscle size in healthy adults. [15]
Last but not least, a study of 40 men found that ashwagandha supplementation significantly increased velocity, physical power, and oxygen capacity during exercise [13].

8. Improves blood sugar balance
Ashwagandha benefits blood sugar balance by regulating glucose levels and improving insulin sensitivity, which means it may be helpful in managing diabetes alongside other treatments and lifestyle factors. A meta-analysis of multiple studies found that ashwagandha supplementation may decrease:
- Insulin resistance
- Blood glucose levels
- Glycosylated hemoglobin (the measurement of your average blood sugar level over the previous 2 months)
[14]
Chronic stress plays a significant role in blood sugar imbalances too, so by reducing levels of the stress hormone cortisol, ashwagandha can also support healthier blood sugar control over time.
How To Use Ashwagandha
Taking ashwagandha in divided doses 2-3 times a day is recommended if you want to experience its full effects. This is because ashwagandha's bioactive compounds usually start to leave the body within 4-14 hours.
Ashwagandha can be taken at any time of the day or night, with or without food. Make sure to take your ashwagandha root supplement regularly for at least 4-6 weeks in order to start seeing results since the activity of ashwagandha is known to accumulate in the body over time. This means that with continued use, its effects are likely to increase as time goes on.
Ashwagandha supplements come in many forms, such as ashwagandha extracts in capsules, ashwagandha gummies, ashwagandha tea, or ashwagandha powder. The form in which you take ashwagandha may change how effective it is.
Ashwagandha extracts are generally the most effective since they contain higher quantities of the bioactive compounds known as withanolides. The efficacy of ashwagandha may also be improved when taken alongside black pepper extract, which enhances absorption.

Is ashwagandha safe for kids?
Ashwagandha is generally considered safe for adults when taken in appropriate doses; however, there is limited research on the safety and efficacy of ashwagandha in children.
It is always best to consult with a healthcare professional or pediatrician before giving any herbal supplement to children. They can provide guidance on the appropriate dosage and help determine if it is safe and suitable for your child's specific needs.
What medications should not be taken with ashwagandha?
Ashwagandha may interact with certain medications, such as:
