Ashwagandha For Muscle Growth. When talking about ashwagandha for muscle growth, yes, it does work. There are several potential mechanisms that could explain this effect; lower cortisol levels, improved sleep and increased testosterone levels.

Ashwagandha For Muscle Growth: Does It Work Or Not?
The most common supplements that come to mind when we talk about muscle growth are usually creatine, whey protein, and BCAAs. These supplements stand on their own yes, but, the herb known as ashwagandha is becoming popular as well.
With ashwagandha supplementation in conjunction with resistance training, you may experience an increase in muscle strength and mass.
Ashwagandha is an adaptogen, a plant substance that helps the body to adapt to stress. This may result in a reduction of elevated cortisol levels in the body.
Even though the body releases cortisol in normal amounts to adapt to exercises, chronically elevated levels of cortisol can inhibit these functions.
So to answer the question: Does ashwagandha help with muscle growth? Yes, it can help!
Does Ashwagandha Affect Muscle Hypertrophy?
The data available on this topic is limited. However, existing evidence suggests that supplementing with ashwagandha can be effective in increasing strength and muscle size.
There have been a couple of clinical trials examining the influence of ashwagandha for bodybuilding leading to muscle size and strength in the context of resistance training. These tests indicate that ashwagandha may have a positive impact on factors such as testosterone levels, recovery, and stress.
Trial 1:

Trial 2:
The other study spanning 8 weeks focused on individuals with prior training experience. There were 57 young men between 18 to 50 years old, and were given either 300mg of ashwagandha root extract or placebo twice daily. They engaged in resistance training four times per week, targeting the upper and lower body, increasing the workout intensity and volume each week.
The results showed that the group supplementing with ashwagandha gained significantly more muscle size in the chest and arms compared to the placebo group.
Additionally, the results indicated that ashwagandha enhanced strength in exercises like the squat and bench press when compared to the placebo.
Other studies show similar results; increased strength compared to placebo. Ashwagandha has positive effects on muscle strength in physically active healthy individuals.
1. Effect On Strength
As described in the studies above, ashwagandha does enhance strength. These effects have been observed in athletes and healthy adults.
If you’re taking ashwagandha for strength, here are some ways in which it indirectly contributes to increased strength:
Stress Reduction
As an adaptogen, it may help the body adapt to stress. Chronic stress can lead to muscle fatigue, so reducing stress may indirectly support strength.
Better Sleep
When you sleep well, your body has the opportunity to repair and build muscle tissue. Ashwagandha has been shown to improve sleep quality in some individuals. We’ll explore this below.
Lower Inflammation
Ashwagandha has anti-inflammatory properties, which may curb excess inflammation that can hinder muscle recovery and growth.
Hormonal Balance
Testosterone plays a role in muscle growth and strength development, and ashwagandha can help maintain testosterone levels.
Ashwagandha has also been associated with improved cognitive function and concentration. It may help you maintain focus during workouts, which is something many trainers struggle with.

2. Effects on Mental Health
Some evidence indicates that ashwagandha can alleviate symptoms of mental health conditions, including depression. However further research is required to fully understand and confirm these potential applications.
The present research does show promising effects of ashwagandha on mental health. It can help people who struggle with motivation and focus for exercise due to poor mental health.
Potential Mechanisms Of Action
We need more research to explain how Ashwagandha extracts improve physical performance and reduce muscle fatigue at a molecular level.
Current studies show that its root extract can enhance cardiorespiratory fitness, and reduce fatigue and recovery time.
1. Indirect Effect Due To Improving Sleep Quality
There is evidence to suggest that ashwagandha can enhance sleep quality. A 12-week study involving 50 adults aged 65–80 revealed that a daily intake of 600 mg of ashwagandha root improved sleep quality and morning mental alertness compared to a placebo.
Another review also displayed anxiety reduction and heightened alertness upon awakening among users. These benefits were evident in individuals dealing with insomnia and those who consumed more than 600 mg daily for a period extending beyond eight weeks.
Improved sleep also has an indirect effect on muscle growth and strength. When you’re asleep, your body produces hormones to rebuild damaged tissue. It also stimulates the growth of muscle fibers. Likewise, if you are not getting enough restful sleep, your muscles will not recover, which will hinder growth.
2. Antioxidant Properties
Antioxidants are essential for our bodies to adapt to exercise but in limited dosages. For instance, some studies found antioxidants like N-acetylcysteine can delay muscle fatigue during a long workout. Based on this, is ashwagandha good for working out? The answer may be yes!
Animal and lab studies have also identified potential ways Ashwagandha's compounds regulate oxidative stress at the cellular level.
For example, withaferin A, a compound in Ashwagandha, can activate a protein called Nrf2, which controls antioxidant enzymes. It helps cells deal with oxidative stress.

3. Cardiorespiratory Fitness
Regarding cardiorespiratory fitness and endurance, Ashwagandha supplementation has been linked to an increase in red blood cell markers. These effects might explain the boost in VO2 max, a measure of endurance. Some research has shown a connection between hemoglobin concentration in the blood, and VO2 max in athletes.
Both women and men seem to benefit from Ashwagandha supplementation.
How Much Ashwagandha Should I Take For Muscle Growth?
To answer that question, ashwagandha supplementation for muscle growth can vary depending on your level of physical activity and training experience.
If you have limited activity and no training experience, go for a lower dose of ≤300 mg per day. If you are trained or an athlete, you can go for a higher dose of 300–500 mg twice per day.
Important Note: These recommendations are guidelines and may vary with individual responses and goals.
Consult with a healthcare professional before starting any new supplement regimen. It is necessary because individual responses to supplements can vary.
The concentration of withanolides in the Ashwagandha supplement may vary. So choose a reputable product with consistent quality and follow the manufacturer's instructions.
When Should I Take Ashwagandha For Muscle Growth?
You can take Ashwagandha every morning for once-a-day supplementation. Unlike other medications and supplementation, the benefits of ashwagandha are not immediate. You can make it a part of your supplemental routine and take it in the morning after your first meal. This way you can benefit from the herb for the day.
Important Note: Like most supplements, it is NOT recommended to take ashwagandha on an empty stomach.
Alternatively, taking ashwagandha at night with milk before going to sleep is also a good idea. Here is a recipe that contains a blend of spices and adaptogens that help in getting a good night’s sleep. Adaptogens are plants and herbs that have been used as Ayurvedic medicine for centuries. The recipe is as follows:
To a glass of warm milk, add half a teaspoon of ashwagandha extract powder with half a teaspoon of cinnamon powder and a teaspoon of honey. Whisk them all together until properly mixed, and drink it all up!
