What to Look for in the Best Ashwagandha Supplement?

Every Ashwagandha supplement purchase should include an evaluation of these aspects:

• Quality and Sourcing: Choose organic Ashwagandha which is grown sustainably because the quality of a supplement depends on its origin and how it is sourced.
• Formulation: Ashwagandha comes in four different formats, including capsules, tablets, and powders as well as liquids.

The effective way to measure dosage lies within capsules, yet powders provide flexible options, yet need some preparation steps.

The strength of liquid extracts is high, but not everybody processes them into their system without difficulty.

• Concentration of Withanolides: Withanolides are the active compounds found in Ashwagandha plants.

Choose an Ashwagandha supplement containing at least 5-10% withanolides because this ensures maximum effectiveness.

The highest withanolide content, along with superior quality, makes Best Ashwagandha KSM-66 supplements recognizable in the market.

“The one thing that most people don't look at when they select a supplement is the quality of the extract. The two that have the most clinical evidence are the one containing the root only, standardized to 5% withanolides, called KSM-66, and the other containing the root and the leaf, standardized to 10% or greater withanolides, called Sensoril. That concentration of withanolide is your baseline reading that a product contains sufficient withanolide to make a difference,” points out Dr. Eleonora Fedonenko.

• Third-Party Testing and Certifications: Before your purchase, select supplements that have undergone independent testing to verify their purity and potency measures.

Three types of certifications that signal product quality include organic, non-GMO, and gluten-free.

“In addition to the type of extract, check for third-party certification by USP or NSF International, as that indicates that what's on the label is what's inside the capsule,” emphasizes Dr. Eleonora Fedonenko.

• Additional Ingredients: Some supplements combine Ashwagandha with other beneficial ingredients like turmeric or magnesium, offering a more holistic approach.
• Brand Reputation and Reviews: Opt for reputable brands with positive customer feedback to ensure quality.
