The best ashwagandha supplements can be a powerful tool to add to your wellness routine.
Ashwagandha has many health benefits, including benefits for mental and physical health, yet it’s a type of herbal remedy that many people aren’t familiar with.
The following is an overview of ashwagandha’s benefits, dosage instructions, and reviews.
We include links to the top supplements if you decide you’d like to start taking it.
What Is Ashwagandha?
Before delving into specific supplements, what is it? It’s also known as winter cherry and Indian ginseng.
Ashwagandha is an Ayurvedic herb, and according to Memorial Sloan Kettering Cancer Center, it may have anti-inflammatory properties. In animal studies, it has been shown to relax the central nervous system.
In Ayurvedic medicine and tradition, ashwagandha is considered one of the most healing herbs available.
In traditional medicine, this herb has been used as an adaptogen.
An adaptogen is something that can help the body adapt to certain types of physical and emotional stress.
Ashwagandha has a medicinal history going back more than 5,000 years for conditions ranging from failure to thrive in children, to insomnia, stress joint inflammation, hormone imbalances, and more.
This herb is in the same family as the tomato and is known as a nightshade.
Ashwagandha is a shrub with round leaves and yellow flowers, as well as fruit that grows to be around the size of a raisin.
It grows natively in India, the Middle East, and northern Africa, and increasingly it’s grown in some parts of the United States.
What Are the Benefits?
There are many ashwagandha benefits backed by research and scientific studies.
According to the Chopra Center, the following are some of the healing properties and benefits of ashwagandha:
Anxiety and Stress Relief
Many of us are plagued by symptoms of anxiety and stress.
When our body is experiencing anxiety or stress, it can cause the release of something called cortisol.
Cortisol is a stress hormone that’s a contributor to our fight or flight response in stressful situations, or when we perceive we’re facing danger.
There are times when cortisol levels naturally rise and then fall; however, because of the ongoing stressors of modern life, many of us have chronically high cortisol levels.
This affects the functionality of our nervous system, glucose levels, gastrointestinal system health, and more.
There is evidence that ashwagandha can help stabilize cortisol levels and encourage our body to maintain healthy inflammatory processes.
These effects and benefits of ashwagandha can promote healthier immune, cardiovascular, and nervous systems.
A study published in the Phytomedicine journal showed one benefit is the herb’s ability to lower anxiety levels. The herb may even be as effective as certain anti-anxiety medicines at reducing symptoms.
Optimal Nervous System Health
Our nervous system includes our brain, and ashwagandha may help ensure our nervous system functions in an optimal way.
It may help promote healthy cognitive function, and naturally stimulate the GABA brain pathways, which can promote a sense of calm.
When you have arthritis, the pain can impede your daily functionality, and you may start relying on pharmaceutical drugs with dangerous side effects.
One study published in the Indian Journal of Medical Research showed because of the anti-inflammatory properties of ashwagandha, it could be effective in the treatment of arthritis, and in particular, rheumatoid arthritis.
As an anti-inflammatory herb, ashwagandha benefits may extend to the heart and the entire cardiovascular system.
A human study published in the International Journal of Ayurveda Research found that using ashwagandha was helpful for improving endurance and muscle strength.
Beyond that, benefits may include lowering blood pressure and cholesterol and helping reduce the risk of heart disease.
Lowering Blood Sugar
A test-tube study looked at the use of ashwagandha to lower blood sugar levels and found that the administration of the herb increased insulin secretion and improved insulin sensitivity.
Human studies looking at people with diabetes and people without having shown ashwagandha can help reduce blood sugar levels.
A study that looked at six people with type 2 diabetes found that using an ashwagandha supplement for 30 days lowered fasting blood sugar levels and a diabetes medication used orally.
Studies in test tubes and animal studies have demonstrated the anti-cancer properties of ashwagandha.
Ashwagandha’s benefits may include killing cancer cells and stoppingkill cancer cells and stop the growth of new cancer cells.
Why these effects?
Researchers believe it could be because ashwagandha can create reactive oxygen species or ROS.
ROS are toxic to cancer cells but not to normal healthy cells.
Animal studies have shown ashwagandha benefits for different types of cancer, including:
- Lung cancer
- Breast cancer
- Colon cancer
- Ovarian cancer
In a study looking at mice with ovarian tumors, when treated with ashwagandha on its own or in combination with an anti-cancer drug, there was a decline in tumor growth of anywhere from 70 to 80%.
The ashwagandha treatment also prevented the spreading of cancer to other organs.
There are currently no human-based studies looking at these effects, although the animal studies show promising results in terms of ashwagandha benefits for cancer.
Along with potentially helping people with anxiety symptoms, ashwagandha may be helpful for symptoms of depression.
A controlled study looked at 64 adults over a period of 60 days. The group who took 600 milligrams of highly concentrated ashwagandha extra each day had a 79% reduction in severe depression.
The placebo group, on the other hand, had a 10% increase in symptoms.
Male Sexual Health and Function
Among the long list of potential benefits of ashwagandha are possible effects on male reproductive health and testosterone levels.
There was one study of 75 men considered infertile. Of those men, the group treated with ashwagandha had increased sperm count and sperm motility.
The administration of ashwagandha also led to significant increases in testosterone levels.
A separate study showed that with three months of ashwagandha treatment, 14% of men’s partners became pregnant.
Ashwagandha can seem like a wonder herb, and in many ways, it can be, but you may wonder if ashwagandha has any side effects.
Typically, the use of ashwagandha supplements is well-tolerated.
Potential side effects are mild in severity and can include headache, drowsiness, or mild stomach upset.
Do be aware that the use of ashwagandha can impact your blood pressure, blood sugar, and thyroid levels so speak with your healthcare provider before you start using it.
As with many herbs and supplements, there aren’t any studies looking at the long-term safety of ashwagandha in a controlled environment.
Sometimes people with autoimmune disorders are advised against the use of ashwagandha as well unless they speak with their doctor.
How To Take Ashwagandha
Ashwagandha can be taken in different forms.
Many people will look for an ashwagandha supplement that comes in a powder form, either in capsules or they might use the powder itself.
There are also liquid extract versions of ashwagandha.
For convenience purposes, people often prefer to use an ashwagandha capsule.
There are also tea-based versions of ashwagandha.
What is the Recommended Ashwagandha Dosage?
The ashwagandha dosage can vary depending on why you’re using it.
Since there aren’t clinical trials yet, there isn’t a standardized dosage, which is common with many top supplements and herbs.
If you’re using a powdered form of ashwagandha, you might use anywhere from 450 mg up to 2 grams.
Most people take a dose of anywhere from 125 to 1,250 mg each day in the studies currently available.
A good rule of thumb is to use a capsule or another form of an ashwagandha supplement with a dosage of around 450 to 500 mg and take it either once a day or twice a day.

If you’re wondering why someone might prefer to take an ashwagandha dosage in tincture form, there are some reasons.
First, a liquid herbal tincture of ashwagandha is going to be better absorbed than the powdered form of the herb in capsule form.
Tinctures are absorbed directly into the bloodstream, while capsules with powdered ashwagandha must be broken down and digested before they can be absorbed.
When an herb is powdered, some of the elements of the plant may not be retained as well as in a liquid extract.
Does that mean powdered versions aren’t effective?
No, that’s not the case and some people prefer capsules because tinctures can taste unappealing.
Regardless if you want a tincture version the version from Hawaii Pharm is excellent and top-rated.

The flexible and unique ways you can use a powdered herbal supplement are why people like these versions.
Another benefit of powder is that it’s pretty economical, and an inexpensive bag can go a long way.
According to reviews of this product, it helps users to feel more even-tempered and mellow. Some users say it helped with their depression symptoms as well.
