What are the negatives of Ashwagandha KSM-66?

Ashwagandha is a popular Ayurvedic herb that has been used for centuries for its many health benefits. It is said to have a calming effect on the mind and body while also boosting energy levels. One popular form of Ashwagandha is KSM-66, which is a patented extract of the herb.

While Ashwagandha KSM-66 has many potential benefits, it does have some potential negatives that people should be aware of before incorporating it into their supplement regimen. Below, we discuss several of these potential downsides.

Potential Side Effects

While Ashwagandha KSM-66 is generally safe for most people, it is not without some potential side effects. Some people have reported experiencing headaches, drowsiness, and digestive issues when taking Ashwagandha. These side effects are usually mild and go away on their own, but some people may find them bothersome.

In rare cases, people may develop an allergic reaction to Ashwagandha KSM-66. This can cause symptoms such as a rash, difficulty breathing, and swelling of the face or throat. If you experience any of these symptoms after taking Ashwagandha, stop taking it immediately and seek medical attention.

Interactions with Medications

Ashwagandha KSM-66 has the potential to interact with certain medications, so people who are taking prescription medications should talk to their doctor before taking it. Ashwagandha has been shown to have sedative effects, so it should not be taken with other medications that also have sedative effects, as this can cause excessive drowsiness.

Ashwagandha can also interact with medications that affect blood sugar levels, so people with diabetes who are taking medication to control their blood sugar should talk to their doctor before taking Ashwagandha.

Possible Thyroid Disruption

One of the potential downsides of Ashwagandha KSM-66 is that it may disrupt thyroid function. While some studies have suggested that Ashwagandha may help improve thyroid function in people with hypothyroidism, other studies have found that it may actually cause thyroid disruption in some people. This is because Ashwagandha contains compounds that can interfere with thyroid hormone synthesis.

People who have thyroid issues should talk to their doctor before taking Ashwagandha KSM-66 to determine whether it is safe for them to take.

Possible Fertility Issues

Some research has suggested that Ashwagandha can lower fertility in men. One study found that taking Ashwagandha for 90 days led to a decrease in sperm count and motility. While more research is needed to determine the exact effects of Ashwagandha on fertility, men who are trying to conceive may want to avoid taking Ashwagandha.


While Ashwagandha KSM-66 has many potential benefits, it is important to be aware of the potential downsides before incorporating it into your supplement regimen. If you experience any negative side effects or have concerns about its effects on your health, talk to your doctor before continuing to take it.
