Also known as Indian Ginseng, Ashwagandha is an herb that has been popular in Ayurvedic medicine for thousands of years. It is chock full of antioxidants and ailment fighting properties which can work wonders for the mind and body.

Ashwagandha is used to reduce anxiety, improve sleep, and enhance cognitive abilities. It is an adaptogen, a healing plant that helps bring the body back into a state of balance.


What is an Ashwagandha Extract?

Ashwagandha extracts are a synthesized form of the herb made from the root or leaf. In other words, it is a more potent form of the plant, which can be up to 8 times more effective than consuming pure root or leaf powder.

Due to Ashwagandha’s popularity, there are hundreds of extracts available on the market (with varying quality). The two most widely known extracts are KSM-66 and Sensoril.

Both of these extracts are heavily tested and researched to ensure their effectiveness and safety. This is not the case for most Ashwagandha extracts on the market.

Most Ashwagandha extracts range from 1.5% to 3% withanolides, which refers to the percentage of active compounds (usually by weight) that are present in the herb. 

KSM-66 and Sensoril have much higher concentrations than the norm, with minimums of 5% and 10%, respectively.


KSM-66 Ashwagandha ExtractWhat is KSM-66 Ashwagandha?

KSM-66 is an award-winning Ashwagandha extract made by a company named Ixoreal Biomed, that took 14 years of R&D to refine.

KSM-66 is the highest concentration of full spectrum root extract on the market. It is full spectrum, meaning it maintains the balance of the various constituents similar to the ratios of the herb itself. In other words, it keeps the same ratios of effective nutrients as the ground root powder, only in a more potent form. 

Instead of using alcohol or chemical solvents to extract, KSM-66 actually uses milk. This makes it safe, effective, sticks true to Ayurvedic tradition, and neutralizes the bitter taste Ashwagandha is known to have.

KSM-66 Ashwagandha has the highest percentage of withanolides compared to any other root-only extract, measuring over 5% by HPLC.

Sensoril Ashwagandha ExtractWhat is Sensoril Ashwagandha?

Sensoril is a high-quality Ashwagandha extract by a company named Nutragenesis. It is a patented, full-spectrum standardized root and leaf extract of Ashwagandha. Sensoril was invented and patented by Shibnath Ghosal with the intention of merging the best of Ayurvedic tradition with the most recent scientific and technology learnings. It is standardized to a minimum of 10% withanolides glyocsides, which is the highest level on the market. Sensoril’s bioactive levels exceed those of conventional root-only Ashwagandha ingredients. This is based on the high percentage of withanolides and the differing mix of nutrients from Ashwagandha leaves.

Sensoril claims to be the most effective and safest Ashwagandha extract available and it has extensive safety records to back up the claim. It’s effectiveness has been tested in 12 clinical studies, 8 of which are “Gold Standard” human clinical trials. 

Here’s one of our favorite Sensoril options:

Some have warned concern of extracts using leaves, such as Sensoril, since it possesses a higher content Withaferin A.  This compound has been linked to Ashwagandha’s cancer-fighting abilities, but it could also be toxic in high doses. The truth is, there haven’t been enough studies to determine whether Withaferin A is good or bad for the body in high doses. Due to the uncertainty, Sensoril ensures health-promoting nutrient ratios are balanced while keeping Withaferin A less than or equal to 0.5%.

  • Minimum of 10% withanolides from root & leaves
  • Passed rigorous safety and toxicity testing that meets FDA-approved guidelines
  • Clinical trials showing improvements in cognitive function, memory, stress-reduction, mood enhancement, sleep, blood sugar balance, cardiovascular health, and pain reduction.

KSM-66 & Sensoril Attributes

KSM-66 ashwagandha extract is made from the root of herb, while Sensoril extract uses both the leaf and roots. KSM-66 has the highest concentration of full-spectrum root-only extract measuring over 5% withanolides. However, Sensoril has the highest level of withanolides on the market with a minimum of 10%. 

The biggest difference between the two is that KSM-66 is made from only the ashwagandha root, while Sensoril is made from both the leaf and roots. Since the withanolide percent is higher with Sensoril, KSM-66 ashwagandha often has a higher dose. 

Both KSM-66 and Sensoril are produced with patented processes that output high quality, effective ashwagandha extracts. Both offer a growing body of studies showing notable benefits to the body and mind. Both are widely used in top Ashwagandha supplements on the market, with impressive customer testimonials.

Sensoril and KSM-66 both use safe extraction processes that neutralize the bitter taste and keep the extract free of nasty chemicals and alcohols.

  • Non-GMO
  • Gluten-Free
  • Vegetarian
  • BSCG-drug free
  • Kosher and Halal Certified
  • No genetically modified
  • Extracted with Water Only – No Solvents Used

Sensoril vs. KSM-66 Ashwagandha – Which is Best?

Both Sensoril and KSM-66 have scientific studies and quality control testing procedures to back up their effectiveness and safety. When it comes to trying out the best Ashwagandha brand, both options are great to try. If 100% Organic is important to you, then KSM-66 is the better bet. Sensoril’s standard process is 95% Organic, but they do offer organic versions of the extract. However, if you have a milk or dairy allergy, Sensoril might be the better option for you. While KSM-66 also makes a completely dairy-free option, the standard extract process uses milk.

If you’re buying the extract in powder form and plan to mix with a food or beverage, KSM-66 might be the better option. Both extracts lessen the natural bitterness of the herb, but KSM-66 is slightly preferred.

You can’t go wrong with either of these extracts. The best approach is to give them both a try and see what works best for your body.
