Ashwagandha is a well-known adaptogen with a growing popularity and research supporting its potential to reduce stress, improve sleep, enhance cognitive function, and boost physical performance. However, as with many popular supplements, not all ashwagandha is created equal.
In this article, I will highlight what to look for in a high-quality ashwagandha supplement, explain its key benefits, and share my top products for 2025.
Proven Benefits of Ashwagandha
Ashwagandha (Withania somnifera), commonly used in Ayurvedic medicine, has a wide range of potential health benefits. While more large-scale, randomized trials are still needed, current research supports its use for:
- Reducing stress, anxiety, and improving mood (1)(2)(3)
- Improving sleep quality, particularly in individuals with insomnia (2)(4)
- Supporting cognitive function, including memory and focus (3)
- Enhancing physical performance, such as muscle strength, endurance, and recovery (5)(8)
- Providing antioxidant and anti-inflammatory support (6)
- Balancing hormones, including thyroid, adrenal, and reproductive hormones, with possible benefits for fertility (7)
What Type of Ashwagandha Supplement is Best?
When choosing an ashwagandha supplement, the form and standardization matter. One of the most trusted and widely studied forms is KSM-66® Ashwagandha.
Why KSM-66 is the “Gold Standard”?
KSM-66 is a full-spectrum ashwagandha extract made only from the root, using a natural extraction process (water or milk, no harsh chemicals). It’s standardized to contain ≥ 5% withanolides, the main active compounds responsible for ashwagandha’s benefits. This ensures consistency from batch to batch.
KSM-66 is:
- Made exclusively from the root (no leaves)
- Standardized for potency (≥ 5% withanolides)
- Extracted naturally without alcohol or synthetic solvents
- Backed by extensive clinical research
Other Ashwagandha Forms: Sensoril® and Shoden®
While KSM-66 is the most studied, two other patented extracts, Sensoril and Shoden, offer higher withanolide content and are more potent in smaller doses.
- Sensoril® Ashwagandha: Contains ~10% withanolides, includes both root and leaf, but can be more sedative.
- Shoden® Ashwagandha: Contains ~35% withanolides, is highly bioavailable and especially effective for sleep and stress, but the research on it is limited.

Best ashwagandha liquid drops
If you’re looking for faster effects, like help falling asleep, you might consider ashwagandha drops instead of capsules. Liquid forms are absorbed more quickly by the body, making them a good option for faster relief. However, it’s important to note that KSM-66 is only available as a powder extract, not as drops. Its extraction process is specifically designed for powder stability. Still, there are high-quality ashwagandha drops on the market. Look for reputable brands that are third-party tested and use alcohol-free bases for the cleanest formulations.

Best Ashwagandha Gummies
As with most supplements, it can be challenging to find ashwagandha gummies made with clean ingredients. They often have longer ingredient lists than capsules or drops, and many contain added sugar. Still, a few reputable brands stand out for their cleaner formulations, and I’ve highlighted the best options of ashwagandha gummies below. Please be avare that gummies are always more expensive than other forms of supplements and are more difficult to have a consistent strength.
Gaia Herbs Organic Ashwagandha Gummies
Servings: 40
Strength per serving: 600 mg

Organic: Yes

You might feel that the ingredient list is long, but the ingredients are clean and there are no fillers or sugar.
This is the best Ashwagandha supplement list that hopefully will help you choose the best supplement for your needs. My recommendation is always going for pills, as they are more potent and stable, especially with extraction methods like KSM-66. But if you like to add Ashwagandha drops to your smoothies or prefer gummies, there are some options for you as well.
