Best Ashwagandha Supplements Brands Reviewed by Dr Aditi

If you feel that your everyday stress is climbing and impacting your health, you are not alone. According to the American Institute of Stress, 75% to 85% of adults experience stress. Dr. Kevin Kett says that we never really start to unwind and disconnect. Chronic mental strain and cognitive overload end up overstimulating the nervous system, keeping the stress hormones at an elevated level. It can impact everything from immunity to sleep quality. 

Many people are turning to supplements containing adaptogens as one of the strategies for stress management. One of the well-researched botanicals, like ashwagandha (Withania somnifera), supports natural stress resilience to cope with emotional and environmental stressors. 

We have created this guide to help you sort through the different ashwagandha supplements and look beyond what’s stated on the label. Nutriessential has analyzed the best ashwagandha supplement brands based on their manufacturing transparency, testing standards, innovative blends, and formulation strategies to help you make an informed choice. 

What’s the Difference Between Trademarked and Generic Ashwagandha Extracts?

When you look at the ingredient list of ashwagandha supplements, you will find that some brands use trademarked extracts like KSM-66®, Sensoril®, or Shoden®. Some simply list ashwagandha as root powder, root extract, or extract of root and leaves. All these matter while choosing supplements because there are differences. How ashwagandha was processed and what extracts are used determine the effectiveness, safety, and purity of the supplement you choose. 

• Ashwagandha powder: If the ingredient list contains this, it means the root is ground into a fine powder. This may contain the natural plant compounds, but the actual concentration of withanolides, the active compounds, is not standardized and is variable. 
• Generic standardized extracts: Some brands, instead of using trademarked extracts use ashwagandha root or root and leaf extracts and they are standardized to 2.5% to 5% withanolides. When you see the word standardized, it means that each dose provides a consistent dosage of the compound, better than raw powder. 
• Branded and trademarked extracts: Supplements containing branded and trademarked extracts are higher priced because of the patented extraction methods. This means every single batch has a uniform chemical composition. Also, the branded ashwagandha extracts are well studied. The three branded ashwagandha extracts used in the best ashwagandha supplements brands are: 
• KSM-66® (Standardized to 5% Withanolides) is a root-only extract that is completely free from chemical solvents. 
• Sensoril® (Standardized to 10% Withanolides) contains extracts from roots and leaves of the plant. 
• Shoden® (Standardized to 35% Withanolide Glycosides) is a highly concentrated root and leaf extract, which is studied to be highly bioavailable. It allows for the use of low dosage of ashwagandha extract compared to supplements containing 500 mg extracts of other forms. 

Top 8 Best Ashwagandha Supplement Brands

Understanding what extract is present in the supplement matters now, especially when many countries are tightening regulations around which part of the ashwagandha plant is used. Ashwagandha, used in traditional ayurvedic preparations, contained only root extracts for oral use. The trademarked extracts containing root and leaves are thoroughly investigated for safety, bioavailability, and quality. Always pay attention to the sourcing of ashwagandha extract before choosing a supplement.
