How Long Does Ashwagandha Stay In Your System

Information about ashwagandha and its reported health benefits is easy to come by, it seems to be popping up everywhere. But it is harder to find detail on the best way to take this Ayurvedic herb. How long does it stay in the body? Should it be taken daily? That’s what we’ll look at in this article.

Key Takeaways

  • The length of time ashwagandha remains in your body varies from person to person and depends on factors like age, weight, dose and metabolism, as well as the specific product you are taking.
  • There are no definitive guidelines regarding the most effective way to take ashwagandha and there is currently no data on the long term use of ashwagandha.
  • Ashwagandha supplementation has been seen to be safe and well tolerated in amounts from 300 mg – 600 mg daily for up to 12 weeks.

Ashwagandha, also known as Indian ginseng, is a herb that has been used for centuries as a traditional Ayurvedic medicine. Various parts of the plant can be used, but in supplements, you will find it is typically an extract of the plant’s roots.

Its root has a horsey smell and is said to confer the strength and virility of a horse. This is where ashwagandha gets its name. In Sanskrit, ashva means “horse” and gandha means “smell”, so ashwagandha literally means “smell of horse”. (Source)

Ashwagandha has risen in popularity in the mainstream following the emergence of clinical research supporting its various health benefits.

Ashwagandha is considered by many as an adaptogen, meaning it can enhance the body’s resilience to stress. 

Having been used for over 3,000 years as an Ayurvedic remedy against various ailments, clinical science has recently linked ashwagandha supplementation to health benefits such as reduced stress and anxiety and improved blood sugar levels, mood, and memory.

Test tube and animal studies suggest that ashwagandha may be beneficial to these various aspects of health, but evidence in human studies thus far has varied. (Source)

How Long Does Ashwagandha Stay In The Body?

There seems to be a theory that ashwagandha may take up to a month to leave the body, with the water-soluble compounds leaving the body between 2-3 days, while the fat-soluble compounds may take a month.

However, there is no significant body of evidence to support this, and in reality, the length of time ashwagandha remains in your body will vary from person to person and depend on factors like your age, weight, dose, metabolism, and health conditions.

It can also depend on the specific product you are taking. Variations between products about extraction methods, formulation, and composition can affect the body’s response.

Can Ashwagandha Be Taken Daily?

Ashwagandha is commonly taken in capsule, gummy, tea, or powder form.

Although there is no standard dosage, studies on ashwagandha have used daily dosages ranging from 120–5,000 mg of a root extract.

The most common dosing protocol is 600 mg daily, divided into two 300 mg doses, with one taken in the morning and the other in the evening, and this has been considered safe for healthy adults. (Source)

It is generally considered safe to take ashwagandha daily, with some studies finding daily supplementation of 300mg for 90 days safe and well tolerated. However, there is no significant data on the effects of taking it in the longer term. (Source)

In some cases, taking high doses of ashwagandha can cause unpleasant side effects such as digestive upset, diarrhea, nausea, and vomiting. (Source

If you are concerned about potential side effects, you might like to start with a lower dose and work your way up as you notice your body’s reaction.

It is always best to consult a healthcare professional about safety and dosage before taking any new herbal supplements, including ashwagandha.

Should You Cycle Ashwagandha?

Questions often crop up around whether taking breaks from ashwagandha supplementation is necessary.

As mentioned, there is currently no data on the long-term use of ashwagandha. There are also no guidelines regarding the optimum amount of time to take ashwagandha for different ailments.

For this reason, only taking ashwagandha for the time specified by your healthcare practitioner is advisable.

Ashwagandha is usually taken with a specific purpose in mind, to manage anxiety for example, and is not traditionally taken continually over an extended period of time.

Stopping to take your ashwagandha supplement after the advised amount of time allows you to assess your feelings without it and potentially reassess your needs. Perhaps you no longer need to take it, or maybe you can reduce your dosage.

This can all be decided through discussion with your healthcare practitioner.

Regarding effectiveness, it is currently not known whether ashwagandha loses its potency with daily long-term usage, but it is a possibility. However, it is also unknown whether taking breaks from ashwagandha or taking it every other day prolongs its effectiveness.

In Summary

Recent evidence supporting the use of ashwagandha for various health issues has contributed to its rise in popularity in the health and wellness space.

While there is evidence from animal and small human studies that suggests ashwagandha might provide certain health benefits, larger human studies are still needed to confirm these benefits.

Definitive guidelines regarding the most effective way to take ashwagandha have not yet been established, but it has been seen to be safe and most commonly taken in a 300 mg dose once a day or one 300 mg dose twice a day, for up to 12 weeks.

As the long-term use of ashwagandha has not been studied and the effects of usage in the long term remain unknown, it is advised to only take ashwagandha for the amount of time specified by your healthcare practitioner.
