KSM-66® Ashwagandha - 5% Nutrition


Ashwagandha may not be the first supplement that comes to mind when you’re planning your cornerstone program. That’s fine, but you’d better plan on adding it to your stack. Why? Ashwagandha is an adaptogen, that’s why. If you’re training as intense as Rich did, you’re placing your body under a ton of physical stress. As an adaptogenic Ayurvedic herb with a long history of use, Ashwagandha can help support healthy stress levels. It can also help you stay in a more anabolic state, improve testosterone availability, and recover faster.

We’re not talking about just any ashwagandha, mind you, but KSM-66® Ashwagandha. What is KSM-66® and what does it do.

Let’s take a closer look at this essential ingredient.

We’ve seen that Ashwagandha helps the body support a healthy response to occasional stress. One way it does this is by combating cortisol. This is, of course, a destructive catabolic hormone. It’s released in response to such things as the physical stress of your brutal Rich Piana-inspired workouts. This means Ashwagandha indirectly affects muscle growth. The reason is that excess cortisol will inhibit the body’s testosterone production. By helping to keep cortisol levels in check, KSM-66® allows the availability of more testosterone.

In addition, the calming properties of KSM-66® Ashwagandha can have a positive impact on food cravings. That means it can help you achieve your recomposition goals. That’s not all. It’s also been shown to have cognitive benefits. These benefits include focus, the ability to pay attention, and the ability to process information faster.

Also, there have been 24 studies conducted on KSM-66®: these include 15 published studies, plus 3 additional studies completed, in peer review and 6 ongoing studies.



KSM-66® Organic Ashwagandha Extract - 1200 mg

KSM-66® Ashwagandha is a patented version of this potent herb. It provides the highest concentration of Ashwagandha, and it’s the most bioavailable. In addition, it’s a full-spectrum extract that took 14 years to develop.

Another reason KSM-66® Ashwagandha is superior is that it uses the root of the plant only. No leaves. Why does this matter? It’s the roots that have the most effectiveness, not the leaves. The research has been done using the root, not the leaves. That’s a big deal. It’s no wonder 5% made sure to choose the most effective form of Ashwagandha on the market. Rich would have done the same!

Two capsules provide 1200 mg. That’s 600 mg per capsule, and that’s more than you’ll get from those unbranded versions. This is the quality you expect from 5%. There can be no doubt. 5% Nutrition Core KSM-66® Ashwagandha should be part of your foundational supplement arsenal. Don’t settle for less quality. Rich went for the best, and you should too! Don’t wait, get yours today!
