What Is Ashwagandha?
Ashwagandha (Withania somnifera) is an herb traditionally used in Ayurvedic medicine.
Today, it is commonly sold as a dietary supplement and is particularly popular among people interested in stress management, sleep, and general wellness.
Research suggests that certain ashwagandha preparations may help with perceived stress and sleep, although the evidence varies depending on the extract, dosage, study, and individual.
Potential Benefits of Ashwagandha
1. Stress Support
Stress management is one of the most researched uses of ashwagandha.
Some clinical studies have reported reductions in perceived stress among adults taking certain ashwagandha preparations.
However, ashwagandha should not be considered a guaranteed treatment for anxiety or chronic stress.
2. Sleep Support
Some research suggests that certain ashwagandha preparations may improve aspects of sleep quality.
This is one reason it has become popular in nighttime wellness routines.
3. Relaxation and General Wellness
Some people use ashwagandha as part of a broader wellness routine focused on relaxation and stress management.
Individual responses can vary, so it is important to follow the product’s directions.
KSM-66 vs. Other Ashwagandha Extracts
When shopping for ashwagandha, don’t look only at the number of milligrams.
Different extracts can have different extraction methods and standardization levels.
KSM-66 is a well-known standardized root extract that appears in many supplement products.
Another branded extract you may see is Sensoril.
The key takeaway is simple: 600 mg of one extract isn’t necessarily identical to 600 mg of another extract.
Look at the complete Supplement Facts label rather than comparing milligrams alone.
How to Choose the Best Ashwagandha Supplement
Before buying, consider these factors:
- Clearly identified ashwagandha extract
- Transparent dosage
- Standardization information
- Third-party testing when available
- Clear Supplement Facts label
- Reputable manufacturer
- Minimal unnecessary ingredients
- Capsule vs. powder preference
- Price per serving
If you’re comparing two products, the cheapest bottle isn’t always the best value. Compare the cost per serving and the actual amount and type of extract.
When Is the Best Time to Take Ashwagandha?
There isn’t one universally proven best time.
Some people take it earlier in the day, while others prefer taking it in the evening as part of a nighttime routine.
Follow the manufacturer’s serving instructions and pay attention to how your body responds.
Is Ashwagandha Safe?
Ashwagandha appears to be tolerated by many healthy adults when used for relatively short periods, but long-term safety is not well established.
Possible side effects can include:
- Stomach upset
- Diarrhea
- Vomiting
- Drowsiness
Rare cases of liver injury have also been reported.
People who are pregnant or breastfeeding, have certain thyroid or liver conditions, or take medications should talk with a healthcare professional before using ashwagandha.
