Ashwagandha, or "Indian Ginseng," a medicinal herb highly prized in Ayurvedic medicine, has surged in popularity in recent years for several remarkable health benefits. From stress reduction to improved sleep and enhanced cognitive function, this adaptogenic herb offers a range of promising advantages.

But, if you've been asking yourself just how much ashwagandha per day you can take safely while still gaining health benefits, you're not alone! Finding the right balance is crucial. Take too little, and the dose may lack effectiveness. Take too much, and you may risk the side effects associated with overdosing.

In this article, we'll explore the general guidelines for consuming ashwagandha safely, plus determine how to vary your dosage for its proven health benefits. We'll also talk about who should avoid ashwagandha and the side effects you should watch out for.

Research shows that the ideal range for health benefits is 250‚Äď1,250 mg for maximum efficacy (see our guide below for more information on dosage for specific health conditions).

You can split the dose to twice daily if that's more convenient. Remember to include the dosage from other non-capsule/tablet ashwagandha sources like ashwagandha tea, ashwagandha root powder, or ashwagandha liquid extract in your final calculation.

If you have any current medical conditions or are taking medications for any specific health challenges, we recommend you check with your physician before you start taking ashwagandha supplements. Ashwagandha may interact with the medications due to its activity on the body's physical and mental processes.

Also, avoid ashwagandha if you're pregnant or breastfeeding. It may increase the risk of miscarriage. Nursing mothers may pass the herbal constituents of ashwagandha to the infant through breast milk.

Ashwagandha Dosage For Specific Health Benefits

What if you want to take ashwagandha for specific health effects like improving immune function or boosting testosterone levels?

We'll be covering this next:

1. Reducing stress and anxiety and improving sleep quality

Based on existing scientific studies, taking 240 mg of Shoden ashwagandha extract per day for 60 days may have a significant effect in reducing stress. Most participants tolerated the extract well and displayed no adverse side effects.

In another study, participants who took a daily dosage of 250 mg and 600 mg per day saw significant reductions in their serum cortisol levels and improvements in their quality of sleep.  Cortisol, incidentally, is your body's main stress hormone.

A study suggests that women aged between 18 and 50 with subclinical hypothyroidism can normalize their thyroid indices by taking 600 mg of ashwagandha root extract daily for 8 weeks. These are preliminary findings, and scientists stress the need to carry out more research before reaching a final conclusion.

2. Boosting memory and cognitive function

Consuming 300 mg of ashwagandha root extract twice daily (600 mg in total) has shown benefits in improving memory (both immediate and general) and cognitive function in adults with mild cognitive impairment (MCI).

According to the specific study, the group that took the ashwagandha showed significantly greater improvement in executive function, sustained attention, and information-processing speed as compared to the placebo group.

3. Increasing testosterone and boosting fertility in men

One study showed that an 8-week course of supplementation with Shoden ashwagandha (600 mg daily) resulted in significant improvements in salivary DHEA-S (male sex hormone found in both men and women) and testosterone levels in healthy males aged between 40 and 70 years.

Taking 5g of ashwagandha per day helps increase sperm count and motility in men over a 3-month period. It also appears to improve sperm quality in highly-stressed men after the same time period, based on the results of the study. 14% of the partners got pregnant.

4. Improving sexual health and fertility in women with HSDD

Taking 300 mg ashwagandha orally twice daily for a period of 8 weeks has been shown to improve female sexual health ( against the parameters of desire, arousal, lubrication, orgasm, sexual satisfaction, and pain) for "otherwise healthy women who do not have any hormonal disturbance." The women who participated in the study were aged between 18 and 50 and were diagnosed with HSDD (hypoactive sexual desire disorder).

Generally, ashwagandha benefits women by balancing their hormones, reducing oxidative stress, and improving fertility.

5. Boosting physical performance and endurance

In a study of 40 elite cyclists, it was seen that supplementation with 500 mg capsules of aqueous roots of ashwagandha twice daily for eight weeks resulted in improvement in cardiovascular endurance, otherwise known as aerobic fitness.

Cardiovascular endurance refers to how well the heart and lungs are able to supply the oxygen you need to exercise at medium intensity. The higher your cardiovascular endurance, the longer you'll be able to exercise at the same intensity without getting fatigued.

Needless to say, boosting your cardiovascular fitness makes your heart and lungs stronger. It also helps you complete the physical tasks you do every day with less effort.

6. Improving thyroid function in women with subclinical hypothyroidism

Based on a study, there is evidence to suggest that taking 600 mg of ashwagandha root extract daily for a period of 8 weeks can help in normalizing thyroid indices in women aged between 18 and 50 with subclinical hypothyroidism.

Some people might initially experience minor discomforts that eventually go away. During the study, some minor and temporary side effects affected 4 out of the 50 participants.

7. Fighting Inflammation

Studies vary on the specifics, but in general, a dosage of at least 250 mg of ashwagandha or 12 mL of ashwagandha extract appears to offer the most benefits for reducing inflammation when taken over a period of one to two months.

8. Boosting muscle mass, strength, and recovery

Research suggests that supplementation of 300 mg ashwagandha root extract twice daily for eight weeks is associated with significant increases in muscle size, strength, and recovery in healthy men aged between 18 and 50 years.

Two divided doses of increasing dosages of ashwagandha daily for 30 days (750 mg/day √ó10 days, 1 000 mg/day √ó 10 days, 1250 mg/day √ó 10 days)also resulted in similar findings.

The research suggests that ashwagandha supplementation may be most useful in conjunction with a resistance training program.

9. Alleviating symptoms of rheumatoid arthritis

Research indicates that ashwagandha may offer relief from rheumatoid arthritis. A study found that taking 250 mg of ashwagandha root extract twice daily led to a suppression of pro-inflammatory cytokines, which are key players in the disease's progression.

This aligns with an animal study that showed reduced arthritis index scores and paw swelling. Both studies suggest that ashwagandha seems to have potential as a natural remedy for this autoimmune condition.

Ashwagandha Side Effects

It's important to start with a small "test" dose first to check for sensitivities. Some people may experience adverse effects such as irritation of the digestive lining, leading to symptoms like stomach upset, diarrhoea, and vomiting. A few may experience drowsiness. Consuming ashwagandha supplements may rarely lead to liver injury.

Stick to recommended doses to avoid the potential side effects of ashwagandha.

Who Should Avoid Ashwagandha?

According to the U.S. National Center for Complementary and Integrative Health, the following categories of persons should avoid consuming ashwagandha:

  • Women who are pregnant or breastfeeding.
  • People with¬†autoimmune or thyroid disorders.
  • Those with hormone-sensitive prostate cancer.
  • People who have to go for a surgery.
  • Individuals with stomach ulcers or liver disease.

Ashwagandha is also best avoided by people who are taking medications for diabetes and high blood pressure. Ashwagandha is also best avoided by people who are taking medications for diabetes and high blood pressure. People taking immunosuppressants, sedatives, anti-seizure medications (anticonvulsants), and thyroid hormone medications should also avoid ashwagandha.


Figuring out how much ashwagandha you should take each day depends on the health benefits you're trying to achieve. Scroll up for the specifics! Start with a small amount before attempting to take the maximum dosage. It is generally considered safe when taken for periods not exceeding three months, although more research is needed to understand its long-term effects. Also, remember that ashwagandha is just one part of staying healthy. Eating well, exercising, and maintaining good mental health are key to staying fit throughout your life!
