NOW KSM-66 Ashwagandha is a highly concentrated, "full-spectrum" root extract used as an adaptogen to help the body manage everyday stress and promote overall well-being. KSM-66 is specifically recognized for having the highest concentration of all major root-only extracts available, which makes it particularly effective for mood and performance.
Primary Uses
- Stress & Cortisol Reduction: It is clinically validated to help the body adapt to occasional stress and lower serum cortisol levels, the body's primary stress hormone.
- Sleep Support: Regular use can promote more restful sleep by improving both sleep quality and duration, helping those who feel "tired but wired".
- Cognitive Function: It supports mental clarity, focus, and memory, and may help reduce "mental fog" or stress-related fatigue.
- Physical Performance & Recovery: Athletes use it to boost muscle strength, endurance, and post-workout recovery.
- Hormonal & Sexual Health: It is often used to support healthy testosterone levels in men and general sexual well-being for both men and women.
Why "KSM-66"?
- Root-Only Extract: Unlike some versions that use leaves, KSM-66 uses only the roots of the Withania somnifera plant, following traditional Ayurvedic practices.
- Standardized Potency: It is standardized to contain a high concentration of withanolides (the active compounds), ensuring you get a consistent therapeutic dose.
- Clinically Studied: It is one of the most researched forms of ashwagandha, backed by numerous human clinical trials for safety and efficacy.
Usage Tips
- Dosage: The standard dose for NOW KSM-66 Ashwagandha is 1 capsule daily (typically 600 mg).
- Timing: It is best taken with food. Because it can have a mild sedative effect in some people, taking it 30 minutes before bedtime may help with sleep.

One of the best shoes
Size: 9.5, Color: Black Polished Full Grain
Outstanding. Fashionable, most comfortable and good construction. No sines of use after quite some time. Highly recommended.

Quality shoe but with a slight squeak.
Size: 10 Wide, Color: Burgundy Polished Full Grain
Nice shoes with the classic Penny Loafer design. Fit was better than another brand I tried. Only reason not 5 starts is disappointment due to a slight squeak at times when walking.

Exact item ordered, quick delivery
Size: 9.5, Color: Black Polished Full Grain
I ordered these black Cole Haan penny loafers for casual wear with jeans, khakies, and even business casual with slacks and a jacket. They've always worked perfectly for these uses. The Cole Haan version is the most versatile and still meets my sophisticated look criteria. I wear a 9 1/2 M with almost all other shoes. I have found Cole Haan to run slightly wider and slightly shorter. This fit will work with thin and no socks and a little loose in width. . I'd likely order a 10 N next time. I tend to forget this but it runs consistent with me for Cole Haan. 5 stars for the shoe and service. My bad on the slightly off fit.

Poor quality control - maybe outlet store leftovers
Size: 11.5, Color: Burgundy Polished Full Grain
The two shoes were not the same size. They were both labeled 11 1/2 but one shoe was larger than the other and the fit was poor. I returned the first pair and ordered a replacement. This time the shoes were close to the same size but too loose and the left one has sewing issues. I've bought Johnston & Murphy for years because of the quality. These were to replace an existing pair of burgundy penny loafers that have finally worn out (even after several heal/sole replacements). That is the expected quality. I suspect Nashville Shoe Warehouse may be handling shoes that didn't measure up for the quality; more like an outlet mall than getting the J&M quality I've come to expect.
Update: went to Johnston & Murphy site to buy "direct" from the manufacturer. There were several recent reviews where the shoes were long and didn't fit properly. Genesco - please step up the manufacture / crafting of these classic shoes to the level of quality they used to have.

Really nice shoes
Size: 9, Color: Black Polished Full Grain
My husband enjoys wearing these shoes. Very classy looking. They fit well. They arrived quickly. He liked them so much he ordered another pair in a different color which have worked out just as well.
