Research has not yet determined exactly how much ashwagandha increases testosterone levels. However, clinical studies on this topic have typically used dosages ranging from 300 mg to 5 g per day.
Did you know? A study published in the American Journal of Men's Health found that ashwagandha supplementation increased testosterone levels by 14.7% compared to placebo in overweight men aged 40-70.
Ashwagandha has gained popularity lately for its potential to boost testosterone levels naturally. But how much ashwagandha should you take per day to see results? Letβs look at the data from the studies.
Understanding Ashwagandha and Testosterone
Ashwagandha (Withania somnifera) is an adaptogenic herb that has been used for centuries in traditional medicine. Recent scientific studies have shown promising results regarding its effects on testosterone levels, particularly in men.
Testosterone is a crucial hormone for male health, influencing:
- Muscle mass and strength
- Bone density
- Fat distribution
- Sex drive (libido)
- Sperm production
- Red blood cell production
- Mood and energy levels
As men age, testosterone levels naturally decline, which can lead to various health issues. This is where ashwagandha supplementation may help.
Research on Ashwagandha and Testosterone
Several studies have investigated the effects of ashwagandha on testosterone levels. Here's a summary of key findings:
- A 2019 study found that men taking 600 mg of ashwagandha daily for 8 weeks experienced a 14.7% increase in testosterone levels compared to the placebo group.
- Another study from 2015 showed that men taking 300 mg of ashwagandha twice daily for 8 weeks had a 15% increase in testosterone levels.
- A 2013 pilot study found that infertile men taking 5 grams of ashwagandha root powder daily for 3 months experienced a 17% increase in testosterone levels.
Recommended Dosage of Ashwagandha for Testosterone
Based on the available research, the recommended dosage of ashwagandha for potentially increasing testosterone levels ranges from 300 mg to 5 grams per day. However, most studies showing positive effects used doses between 300-600 mg daily.
Here's a summary of effective dosages from various studies:
Study |
Daily Dosage |
Duration |

It's important to note that these studies used different forms of ashwagandha (root extract, root powder) and had varying durations. The optimal dosage may vary depending on individual factors such as age, overall health, and specific health goals.
How to Take Ashwagandha for Testosterone Support
When using ashwagandha to support testosterone levels, consider the following tips:
- Choose a high-quality supplement: Look for products that use root extract standardised to contain at least 5% withanolides (the active compounds in ashwagandha).
- Start with a lower dose: Begin with 300 mg daily and gradually increase if needed.
- Be consistent: Take ashwagandha daily for at least 8-12 weeks to see potential benefits.
- Consider splitting the dose: Some studies used divided doses (e.g., 300 mg twice daily). This may help maintain more consistent levels in the body.
- Take with food: Ashwagandha is fat-soluble, so taking it with a meal containing some healthy fats may improve absorption.
- Be patient: Hormonal changes take time. Don't expect immediate results.
Potential Side Effects and Precautions
While ashwagandha is generally considered safe for most people, it's important to be aware of potential side effects and precautions:
General Safety Profile
Ashwagandha is generally considered safe for most people when used as directed. However, long-term studies specifically designed to evaluate its safety are still needed. Most clinical trials have used ashwagandha for periods of 8-12 weeks, so effects of prolonged use are not well-established.
Common Side Effects
Some individuals may experience mild side effects when taking ashwagandha:
- Drowsiness and sedation: Ashwagandha may cause mild drowsiness in some people, which could affect activities requiring alertness.
- Digestive issues: Some users report mild gastrointestinal discomfort, including nausea or diarrhea.
- Headaches: In rare cases, ashwagandha use has been associated with headaches.
Rare but Serious Concerns
Liver Toxicity
Several case reports have raised concerns about rare occurrences of liver toxicity associated with ashwagandha use. Key points to consider:
- Liver toxicity was typically reported within 2-12 weeks of starting ashwagandha.
- In most cases, liver function returned to normal after discontinuing ashwagandha and receiving medical support.
- It's important to note that these adverse effects were not observed in larger clinical safety trials.
While the exact mechanism is unclear, an in vitro study suggested that withanone (a component of ashwagandha) might have toxic effects when cellular levels of the antioxidant glutathione (GSH) are low. However, this research is far from conclusive.
Thyroid Function
Some case reports have suggested that ashwagandha might affect thyroid function. However, these effects were not observed in larger safety studies. Individuals with thyroid disorders should consult their healthcare provider before using ashwagandha.
Special Precautions
- Pregnancy and breastfeeding: Due to a lack of safety data, pregnant or breastfeeding women should avoid ashwagandha.
- Autoimmune diseases: Ashwagandha may stimulate the immune system, potentially exacerbating symptoms of autoimmune conditions.
- Surgery: Stop taking ashwagandha at least two weeks before scheduled surgery, as it may affect blood pressure and blood sugar levels.
- Diabetes: Ashwagandha may lower blood sugar levels. Diabetics should monitor their blood sugar closely and consult their doctor before use.
- Hormone-sensitive prostate cancer: Since ashwagandha may affect hormone levels, men with hormone-sensitive prostate cancer should avoid its use without medical supervision.
Drug Interactions
Ashwagandha may interact with several types of medications:
- Thyroid hormone medications: Ashwagandha might increase thyroid hormone levels, potentially interfering with thyroid replacement therapies.
- Immunosuppressants: Due to its potential immune-boosting effects, ashwagandha might counteract immunosuppressant drugs.
- Sedatives: The mild sedative effect of ashwagandha could potentially increase the effects of sedative medications.
- Blood pressure medications: Ashwagandha may have a mild effect on blood pressure, potentially interacting with anti-hypertensive drugs.
- Blood sugar medications: Given its potential to lower blood sugar, ashwagandha might enhance the effects of diabetes medications.
Long-term Use Considerations
The long-term effects of daily ashwagandha use are not well-established. Some considerations:
- It's unknown if ashwagandha loses potency with prolonged daily use.
- The effects of cycling (taking breaks) or alternate-day dosing on long-term effectiveness are not clear.
- Due to its potential effects on neurotransmission, tolerance development cannot be ruled out.
Monitoring and Best Practices
- Start with lower doses: Begin with 300 mg daily and gradually increase if needed and tolerated.
- Regular check-ups: If using ashwagandha long-term, schedule regular check-ups with your healthcare provider, including liver function tests.
- Be alert to changes: Pay attention to any unusual symptoms, particularly in the first 12 weeks of use.
- Quality matters: Choose high-quality supplements from reputable manufacturers to minimize the risk of contaminants.
- Discontinue if needed: If you experience adverse effects, stop taking ashwagandha and consult your healthcare provider.
Remember, while ashwagandha shows promise for supporting testosterone levels and overall health, it's not a substitute for a healthy lifestyle. Always consult with a qualified healthcare professional before starting any new supplement regimen, especially if you have pre-existing health conditions or are taking medications.
Beyond Supplementation: Lifestyle Factors for Testosterone Support
While ashwagandha may help boost testosterone levels, it's important to consider other lifestyle factors that can support healthy testosterone production:
- Exercise regularly: Resistance training and high-intensity interval training (HIIT) can help increase testosterone levels.
- Maintain a healthy weight: Excess body fat can lead to lower testosterone levels.
- Get enough sleep: Aim for 7-9 hours of quality sleep per night.
- Manage stress: Chronic stress can negatively impact testosterone production.
- Eat a balanced diet: Include foods rich in zinc, vitamin D, and healthy fats.
- Limit alcohol consumption: Excessive alcohol intake can lower testosterone levels.
Finding the Right Dosage for You
While research suggests that ashwagandha may help boost testosterone levels, the optimal dosage can vary from person to person. Starting with 300-600 mg daily and monitoring your response is a sensible approach for most individuals.
Remember that supplements should complement a healthy lifestyle, not replace it. Combining ashwagandha supplementation with regular exercise, a balanced diet, adequate sleep, and stress management techniques may provide the best results for supporting healthy testosterone levels.
