Who Should Buy Ashwagandha?
The benefits of Ashwagandha are outstanding, and many of them can be backed up by research and clinical trials. Ashwagandha has been used for centuries to help with concentration levels and increasing mental clarity (1). It’s believed that the high level of withanolides helps reduce inflammation and reduce tumor growth (2, 3).
It’s also been shown in studies to reduce blood sugar levels (4). This makes it an excellent option for reducing stress, managing body weight, and even building muscle. There’s a good reason that this herb has been used in medicine for over 5,000 years.
Ashwagandha appears to be safe for most individuals but may interfere with immunosuppressants and sedative medications. Pregnant women, diabetics, and people with thyroid issues should not take ashwagandha.
If you have any concerns, it’s always important to speak to your doctor before starting a supplement regimen with ashwagandha.
How We Ranked
The first thing we looked at when ranking the best Ashwagandha products on the market was the dosage and delivery method. On average, we wanted each product to provide at least 400mg per serving, as this allowed for easy dose tailoring and good value. Capsules were preferred, mainly because of dosage accuracy and taste. We did include powder-based products if they were of site quality, as in the case of Rootalive Organic Ashwagandha.
Next, we looked at the extraction process. There are a few ways to extract ashwagandha, with the best being supercritical carbon dioxide extraction. This method helps to maximize the dose of the active ingredients, providing a more powerful and pure supplement – a main reason why Himalaya ranked in our top 5.
Added ingredients were also important to consider. Products that contained a lot of filler sand stabilizers were either eliminated or ranked low, as in the case of NOW supplements. Supplements that included beneficial ingredients like BioPerine, which helps improve absorption, were rewarded accordingly.
Lastly, we looked at purity. Because ashwagandha is taken as a concentrated plant extract, we had a high preference for certified-organic products. This ensured we would get no pesticides or herbicides in our supplements, and was a main reason why our top choices like Essential Elements and Nuzena ranked so well.
Ashwagandha can help improve blood sugar levels. There have been several studies that show that Ashwagandha can lower blood sugar levels for those who have both relatively normal levels and diabetes. One study showed that Ashwagandha increased insulin secretion and insulin sensitivity in muscles (5).
Another small study from the Indian Journal of Experimental Biology suggests that participants with type 2 diabetes showed a vast improvement in their fasting blood sugar levels over 30 days. However there was no control group present during testing (6).
Ashwagandha can help reduce cancer cell growth. Apoptosis is the death of cancer cells, and this is due to the levels of withaferin within the herb. Withaferin is connected to the promotion of the ROS inside cancer cells, which is the reactive oxygen species that disrupts their function.
While there is minimal testing on humans and a lack of clinical trials available, tests on animals and in test tubes show that the ancient herb may be able to impede the growth of cancer cells and help induce apoptosis (7).
Other successful animal tests show that Ashwagandha may be able to treat a variety of cancers, including lung, brain, ovarian, breast, and colon cancers (8).
A 2014 study completed by PLOS ONE showed that mice with tumors on their ovaries were treated with withaferin, either alone or with an anticancer drug, and they showed up to 80% reduction in tumor growth and prevented cancer from spreading (9). While this hasn’t been shown in humans, the research is promising.
Ashwagandha can help improve mental wellbeing. Ashwagandha is known for its mental health-boosting properties. There have been several studies that show that the herb can help reduce cortisol levels, which directly affects stress levels.
The adrenal gland releases cortisol in stressful situations, and cortisol levels can become elevated at all times. When cortisol levels become chronically elevated, it can negatively impact blood sugar levels and increase body fat storage (10). In one study, the participants who took ashwagandha showed a 30% reduction in cortisol levels compared to the control group.
Along with cortisol levels, the stress pathways in the brain are potentially regulated by Ashwagandha, as shown in rat testing. In human trials, it’s been shown that it can help reduce the stress associated with anxiety disorders but should not be used as a replacement for doctor-prescribed medication without supervision.
In one study of 64 participants, over 60 days, showed an almost 70% reduction in anxiety and insomnia versus the control group, who only showed 11%(11). In another study, almost 90% of participants reported reduced anxiety, whereas those who took the placebo showed 50% of participants felt a reduction in anxiety (12).
Ashwagandha may be able to reduce the effects of depression. Unfortunately, this hasn’t been thoroughly studied. One participant who was studied for the effects on anxiety reported a reduction in depression as well, but they were the only participant with a history of depression, so the results are unclear.
Ashwagandha may improve infertility. There is a strong connection between Ashwagandha and reproductive health, particularly in testosterone levels in men. In a study of 75 men struggling with infertility, Ashwagandha was shown to increase sperm mobility and overall count.
It also showed that participants had a significant testosterone increase and antioxidant levels in the blood. Another study showed that the herb had a positive impact on sperm quality, resulting in 14% of participants’ partners becoming pregnant after three months of treatment (13).
Ashwagandha can improve muscle growth and body composition. Ashwagandha has shown to impact muscle growth, strength, and body composition. In fact, many individuals who have taken the herb show an improvement in strength after 30 days. In one particular study, Ashwagandha was shown to reduce body fat twice as much as the control group (14).
Ashwagandha helps reduce inflammation. It’s been shown that Ashwagandha may help with overall inflammation in the body. The herb has shown to increase natural killer cells activity, which are the cells that fight infection, keeping your body healthy.
Ashwagandha also decreases markers of inflammation, like CRP, or C-reactive protein. This particular marker is linked to heart disease. Taking the supplement can result in up to a 35% reduction in CRP.
Ashwagandha can help improve cholesterol levels. For those looking to lower cholesterol and triglycerides can turn to Ashwagandha for a natural aid.
There have been significant results through animal studies, but the human trials have shown less of an impact, but there are results reported. Studies have shown up to a 17% decrease in LDL cholesterol and an 11% decrease in triglycerides in humans.
Ashwagandha helps improve memory and cognitive function. While there hasn’t been much human research into the impact on memory and brain function, there have been positive results through test-tube and animal testing.
Whether there have been brain function issues from disease or injury, there has been a positive impact on memory from taking Ashwagandha. Due to the promotion of antioxidants and the protection of cells from free radicals, the herb could help with memory issues.
In a study with rats who suffer from epilepsy, the herb helped to reverse almost off the spatial memory impairment caused by the seizures, which might be linked to less oxidative stress.
One of the big benefits that have been tied to the herb is memory and cognitive improvement, but there aren’t many studies completed to back up the claims. However, the studies that have been performed show a positive increase in clarity and productivity. In an 8-week study of 50 participants, there was a positive increase in memory, performance, and focus (15).
Q: Can you take Ashwagandha long term?
While the effects of taking Ashwagandha long-term are not really known, research suggests that taking it up to three months is the ideal time frame. Once the three months are surpassed, it could cause upset stomach, vomiting, and diarrhea.
Q: Is Ashwagandha safe for diabetics? For those who want to use Ashwagandha to lower blood sugar levels, it could interfere with any prescription medication, so please consult your doctor before use. When combined, it could cause very low blood sugar, and if you’re diabetic, you should monitor your levels closely.
Q: Does Ashwagandha affect blood pressure?
When using the herb to impact blood pressure levels, it should not be used if you have low blood pressure, as it lowers it naturally. It can interfere with blood pressure medication, so use with caution and the supervision of a doctor. If you have stomach ulcers, the herb may impact the GI tract negatively, so do not use it if you have ulcers.
Q: Can Ashwagandha be taken by people with auto-immune disorders?
If you have an auto-immune disease like lupus, MS, rheumatoid arthritis, or numerous other diseases, Ashwagandha may increase the activity in the immune system, which may amplify any symptoms felt by these diseases. It’s best to avoid using the herb in this case.
For those who suffer from thyroid issues, the herb may negatively impact hormone levels, so any hormonal medications could negatively interact with it.

Always consult your doctor before taking on any lifestyle change and adding supplements that promote weight loss into your routine.
Q: Will Ashwagandha help my anxiety?

Q: Can I take Ashwagandha with water?
Yes, many people take Ashwagandha with water. It’s also common to take it with milk. Many people mix the powdered supplement into coffee and tea in the morning. A popular option is to take it with ghee, warm milk, and honey. Depending on your preference, you could also add it to a smoothie.
Q: How soon will I see results with Ashwagandha?

Q: Can I take Ashwagandha on an empty stomach?

If you are sensitive to many foods or are allergic to nightshades, you may have trouble taking Ashwagandha. Individuals who are allergic to Ashwagandha may have a skin rash, difficulty breathing, shortness of breath, chest pain, gas, bloating, diarrhea, and itchiness as common side effects.

Q: Does Ashwagandha help with OCD?
Ashwagandha may be one of the most prevalent herbal remedies for OCD available today (16). It works to balance the chemistry of the brain, reduce stress, and stimulates BDNF. The herb helps to reduce compulsive urges, anxiety, and stress, which are all beneficial factors in treating OCD.
While no clinical trials have been done to provide supportive research, there are many individuals who have had their lives changed because of Ashwagandha. Taking prescription medication is a great option for some patients of OCD, but not all. There can be undesirable side effects.
The withanolides in Ashwagandha helps regulate hormones. OCD is thought to take place in the basal ganglia, and Ashwagandha can help tame excited brain activities. It may also be able to repair some of the damage done to neural networks and transmitters.

It has a positive impact on muscle growth, and body fat may result in improved skin. It works to improve reproductive health and hormone levels, which may help slow the aging process.
Q: Can children take Ashwagandha?
Ashwagandha has been shown to be safe for children and teenagers and promotes a variety of benefits for them. Children are building their immune systems, so the herb can provide a much-needed boost to protect them from the germs they come in constant contact with.
Like in adults, the herb can help reduce stress and anxiety in children and teens, resulting in better sleep and mental clarity. It can help improve focus and memory, which can be super beneficial through the school years. If your child struggles with food or a poor appetite, Ashwagandha may be able to help, as it regulates body weight while promoting strength.
Children have sensitive immune systems, so dosages will need to be smaller for youth. Please consult your doctor before providing them with the supplement. Typically, they would be getting all the benefits of Ashwagandha with 300mg per day dosage in the morning with breakfast.
For kids, it takes about a week to start seeing the impact, but that is different for everyone. If that dosage doesn’t seem to be enough, an addiction 300mg may be given in the afternoon, around 4 hours before bedtime.
Q: Can I take Ashwagandha daily?

Because Ashwagandha reduces cortisol levels, the stress hormone, this can positively impact the severeness of PCOS symptoms in women.
Q: Can Ashwagandha make me high or intoxicated?

If you have questions about this or are experiencing rashes or itchiness, please consult your doctor or pharmacist.
Overall, ashwagandha is an affordable way to boost your mental wellbeing, increase concentration, and reduce anxiety in those who don’t have underlying health conditions.
While the long-term impact of using ashwagandha is unknown, it’s typically safe for most people to use. We always recommend discussing your supplement regimen with your doctor before introducing a new supplement.
