Key Takeaways

  • Consumers often take 1-6 grams of Ashwagandha root powder daily, though the dosage varies depending on the intended use.
  • The exact dosage you need also depends on your health condition, weight, age, and other biological factors. You may need to start with small doses and increase as needed.
  • Some people should not take Ashwagandha, like those with thyroid problems or who are pregnant or breastfeeding. Talk to your doctor before adding Ashwagandha to your wellness routine.

How Much Ashwagandha Should You Take Daily?

If you’re planning to add the herbal supplement to your daily wellness routine, you’ll want to consider all of the factors that impact the necessary daily dosage of Ashwagandha. For instance, your weight, age, health condition, and reason for taking Ashwagandha will all impact the amount you need to take.

The reason you’re taking Ashwagandha will most heavily impact the dosage you need. If you take other herbal supplements or medications to achieve the same results, you may find that you need to take less Ashwagandha. In general, we recommend starting on the low end of the dosage threshold and increasing your dose slowly until you feel the desired effects.

Also keep in mind that Ashwagandha is sold as a supplement in the U.S., which means that the dosage size is not standardized. You should pay close attention to the dosage of any product you choose.

On average, people take between 1 and 6 grams of the whole ground herb daily. That’s between 1,000 and 6,000 milligrams of whole Ashwagandha root powder.

If you are taking a multi-functional blend that includes Ashwagandha, make sure you pay attention to the proper dosage threshold for other ingredients when adjusting your dosage. These types of formulas are common, and it may be best in this case to just follow the recommended dosage on the label.

Ashwagandha Dosage for Anxiety

Some evidence suggests that ashwagandha supplementation can help lower cortisol (stress hormone) levels, although more evidence is necessary to understand how much Ashwagandha to take for anxiety. In one study, subjects took daily doses of 125 mg to 5 grams for 1–3 months and experienced a 11-32% decrease in cortisol levels.

Other studies (2000, 2009, 2012) used between 500–600 mg of ashwagandha per day for 6–12 weeks with positive results in reducing anxiety and insomnia in subjects with anxiety disorders.

Ashwagandha Dosage for Athletic Performance

In one 8-week study, men took 500 mg of Ashwagandha daily and were reported to experience a 1% increase in muscular power compared to no change in the placebo group.

Another study used 600 mg of ashwagandha daily and found a 1.5–1.7 times larger increase in muscle strength and 1.6–2.3 times higher increase in muscle size.

Some similar studies used higher doses with similar effects. The dosage typically ranged from 750–1,250 mg of ashwagandha taken daily for 30 days.

What's the Best Way to Take Ashwagandha?

There are many different ways that Ashwagandha root is used traditionally, and you may find examples of the whole root being used or of it being ground and mixed into a frothy beverage, like warm milk. We're going to focus on the more standardized versions of Ashwagandha that are commonly used today. When shopping for Ashwagandha supplements in today's market, you'll find two common dosing forms–capsules and powder.

Dried ahswagandha root after being ground into powder, a common dosing form used for daily supplementation.


Ashwagandha powder is one common dosing form that offers some unique benefits, like the ability to accurately measure the dosage each time. Ashwagandha powder can be mixed into your favorite foods or drinks, and some sources suggest that powder may have a better absorption rate since it’s often taken with plenty of fluids, but there is no evidence to support this claim.


Capsules are simply pre-measured, encapsulated doses that are great for daily dosing at any time of day. You won’t need to measure the dosage each time, and many people love this flavorless Ashwagandha dosing option.
