What is Ashwagandha?

Ashwagandha (Withania somnifera) is a herb that has been used for its medicinal qualities for many centuries. The use of ashwagandha as a herbal remedy can be traced back to Ayurvedic medicine, one of the world’s oldest traditional medicine systems. “Ashwagandha” is Sanskrit for “smell of a horse”, which most likely refers to the invigorating and aphrodisiac effects of this ancient herb. It may also refer to the actual smell of the herb’s roots.

The plant itself is hardy and can survive and grow in harsh conditions. The stem can reach 2 meters in height, with branches that carry green leaves and orange-red fruits that are reminiscent of small tomatoes or berries.

What Are Ashwagandha Supplements?

Ashwagandha supplements generally come in the form of capsules that contain ashwagandha root or fruit extracts or powdered whole roots. Withanolides, the main active compound in ashwagandha supplements, are responsible for providing the medicinal benefits.

The best ashwagandha supplements contain anywhere from 1.5-5% of withanolides. However, not all withanolides are good; withaferin A is a toxic compound that should be avoided. Top ashwagandha supplements contain negligible concentrations of this compound, making them safe for consumption.

Uses & Benefits of Ashwagandha

Ashwagandha is an adaptogenic herb that’s popular in ayurvedic medicine. It’s been used for thousands of years by traditional medicine practitioners, but modern science is just beginning to catch up with ancient practices. Some of the most-studied potential benefits of ashwagandha include:

  • Anxiety & stress: Ashwagandha may have a beneficial effect on anxiety and stress levels in adults. In one 12-week study, two groups of patients were given either a standardized psychotherapy treatment or a naturopathic treatment regimen including ashwagandha. At the conclusion of the trial, the group given ashwagandha showed greater clinical benefits than the control group, including reduced anxiety and improvements in concentration and social functioning. This study also found very few noteworthy side effects, leading some experts to recommend ashwagandha as a potential alternative to antidepressant and anti-anxiety medications. Some studies have also found benefits for addressing depression, although more research is needed.
  • Thyroid function: Ashwagandha can have a positive effect on thyroid function. Interestingly, it’s thought that it may benefit both underactive and overactive thyroids. A recent study found ashwagandha to be beneficial in normalizing thyroid levels in participants, while another study also noted improvements in thyroid function after taking ashwagandha. More research is needed, but ashwagandha holds some promise in addressing thyroid issues.
  • Blood sugar: Ashwagandha may help to normalize blood sugar levels. An animal study found that the phenolic compounds found in ashwagandha possess hypoglycemic properties, which may help to normalize and balance blood sugar levels in diabetic rats. It may also benefit insulin resistance and inflammatory markers, two contributors to diabetes symptoms. It’s important to note, however, that most studies examining ashwagandha’s potential effects on blood sugar have been animal studies, so more research with human participants is needed.
  • Cancer: Ashwagandha may have anti-tumor effects, although more research is needed. It’s thought that the herb may help to prevent the growth of cancer cells, thanks to its antioxidant and immune boosting properties. It’s also thought that ashwagandha may help to minimize the side effects of existing cancer treatments, leading some researchers to recommend it to cancer patients undergoing treatment. Ashwagandha is thought to increase white blood cell count, which may boost immune activity and help to keep the body healthy. Chemotherapy and other cancer treatments typically lower white blood cell count, so the addition of ashwagandha for chemotherapy patients may be beneficial.
  • Cognitive function: There is some evidence to suggest that ashwagandha may have a positive effect on cognitive function and memory in old age. Other studies have found that it may also help reduce the risk of developing Alzheimer’s disease and neurodegenerative diseases. In various clinical studies, ashwagandha has shown promise in improving memory, information processing, and mental skills in adults. More research is needed.
  • Immune system: Ashwagandha and other adaptogens can help to boost immune system function by reducing stress hormones in the body. It may also help suppress pro-inflammatory cytokines, which helps to cultivate an anti-inflammatory environment within the body. Animal studies have shown positive effects in this regard, but more research with human participants is needed.
  • Endurance: Ashwagandha may help to enhance physical endurance and stamina, particularly in active individuals. It’s thought that the herb may reduce physical pain during workouts, while stimulating brain function, leading to enhanced concentration and stamina. It’s also thought  to be beneficial for building muscle and strength. More research is needed.

In addition to the potential benefits listed above, ashwagandha is a potent antioxidant containing many beneficial compounds. Antioxidants are potent health boosters that can affect a wide range of health markers. More research is needed on this herb, but evidence so far is quite promising.

Who Can Benefit from Ashwagandha?

  • People who suffer from anxiety and stress – This clinical study demonstrated a significant decrease in anxiety levels in people receiving ashwagandha extract as well as dietary counselling and deep breathing technique education. The outcomes were measured on the recognized Beck Anxiety Inventory.
  • People with diabetes – Although it is still under investigation, ashwagandha has shown promise in controlling blood sugar levels in a human clinical trial.
  • People with high blood cholesterol – Studies conducted on hypercholesterolemic lab rats have demonstrated the potential benefit of ashwagandha as a cholesterol-lowering agent. Studies which investigated ashwagandha’s hypoglycemic (sugar lowering) effects also often explored its role in lowering blood lipid levels. These studies have shown a potential benefit, but more research is needed.
  • People with chronic inflammatory conditions – A lab study demonstrated an ability of ashwagandha to suppress the production of proinflammatory substances in samples from patients with rheumatoid arthritis, as well as from healthy volunteers.
  • Males with sexual performance issues or infertility – Ashwagandha root extract may be beneficial for treating stress-related male infertility, as demonstrated by this study. Another clinical study showed an increase in testosterone and other sex hormone levels in men being investigated for infertility, as well as an increase in semen quality. This is possibly due to ashwagandha’s antioxidant qualities.
  • People who wish to boost their muscle mass and strength – Combined with a resistance training program, ashwagandha extract was shown to boost muscle mass and strength, as well as general cardiorespiratory fitness in healthy volunteers.
  • People with Parkinson’s disease – Although no human clinical studies that support the use of ashwagandha in Parkinson’s disease currently exist, lab rat studies have shown a potential neuroprotective effect. This study demonstrated an improvement in cognitive and psychomotor performance in healthy volunteers receiving ashwagandha root extract capsules.
  • People with cancer – This lab study has shown that some withanolide compounds may have the ability to suppress the growth of some human cancer cells. Another study indicated that ashwagandha may sensitize cancer cells to radiotherapy and may be used as an adjuvant chemotherapy agent.
  • Everyone else – Due to its low risk profile and potential benefits as mentioned above, ashwagandha may be safely taken by healthy people who wish to boost their overall health and wellbeing.

*It is important to note that the currently existing evidence does not support using ashwagandha as a standalone therapy or as a substitute for conventional therapy for any of the above indications. Consult your physician before making any changes to your treatment regimen.

Taking Ashwagandha

The traditional method of taking ashwagandha is to mix the herb’s root powder with ghee and honey or adding it to tea. A more convenient method is taking it in pill form. The best ashwagandha supplements come in capsules that contain ashwagandha extract or powdered whole roots.

The ashwagandha supplement dosage that is recommended by most sources is anywhere between 500 and 1,000 mg of the supplement per day. Even relatively low doses should enable you to experience the ashwagandha benefits.

You may find a variation among the dosages of the top ashwagandha supplement brands, so it is recommended to check the recommended ashwagandha supplement dosage specific to your brand before taking it.

Beneficial Ashwagandha Stacks

This great ashwagandha stack is recommended by many people for combating stress and anxiety:

  • 500 mg ashwagandha with breakfast and dinner (1,000 mg per day)
  • 300 mg bacopa once daily with food

Since ashwagandha and bacopa are both adaptogens and anxiolytics, the combo may cause some lethargy and decreased motivation. If you experience this, you may substitute the bacopa for 100 mg rhodiola (mild stimulant) once daily with food or simply add the rhodiola to the aforementioned ashwagandha stack.

Ashwagandha Side Effects

Side effects are mild and may include stomach upset, diarrhea, and vomiting with larger doses.

The safety of ashwagandha during pregnancy and lactation has not been well evaluated. Therefore, avoidance is recommended.

If you suffer from any medical conditions, consult your physician before taking ashwagandha.

What to Look for in a Good Ashwagandha Supplement

You should be on the lookout for ashwagandha supplement brands that list the standardized % content of withanolides in the product. The most powerful ashwagandha supplements may have up to 5% withanolides. You may see “KSM-66” mentioned with some brands; this is an extraction method that standardizes the withanolide content to around 5%.

The best ashwagandha supplements are made by reputable brands that adhere to GMP (Good Manufacturing Practices) standards, and you can trust that the info on their packaging is accurate.

As with any other supplement, you may want to stick to non-GMO organic ashwagandha supplements.
