KSM-66 Ashwagandha: Can it Improve Testosterone, Libido, and Sleep?

Read time: 4 minutes

Coming up: sleeping better, reducing stress, some self-indulgent anecdotes, boosting your libido, horrible facts, strange letters and numbers, healthy things that might not really be healthy, and why not all Ashwagandha is equal.

👉 You’ve heard of Ashwagandha.

… and you’ve heard of supplements that include Ashwagandha.

But there are many different types of the stuff—and many different ways to take it:

So what’s the difference between them? Which one should you take? Which is best for reducing my stress and improving my sleep? How can I get the biggest boost for my libido and testosterone? What exactly is KSM-66 Ashwagandha? And why are we asking you so many questions?

💪 I’m Rob: entrepreneur, father of two, and co-founder of Sentro Labs. Here’s why KSM-66 Ashwagandha is one of my favourite supplements…

Ashwagandha, extracts, numbers, and letters

Ashwagandha is a plant 🌱

… and it’s been used for 1000s of years in traditional Indian medicine.

There are different ways to produce it, extract it, and consume it. But, of course, you can’t really just eat the plant (well, definitely not here in Ireland anyway).

Of all the extractions and concentrations, KSM-66 Ashwagandha is widely recognised as the best—it’s a more-powerful, more-concentrated, more-pure form of Ashwagandha. And it serves up “the highest concentration of all major root-only extracts available on the market today.”

In studies, KSM-66 Ashwagandha has shown the ability to:

Boost immune function
Improve memory and cognition
Increase endurance and strength
Improve sexual function in men AND women

… and, most importantly, since you’re reading this blog post, KSM-66 Ashwagandha might also be able to:

Increase male testosterone
Reduce stress and enhance sleep

(more on both coming next)

Symptoms of low testosterone (and why you’re probably suffering—even if you don’t know it)

From around age 35, male testosterone levels drop by around 1-2% per year…

… and if you’re in this age range, it’s probably happening to you right now.

Symptoms of low testosterone can include:

Decreased sexual function
Difficulty building muscle
Always feeling tired
Increased stress
Lower sex drive
Higher body fat
Mood swings
Less energy
Poor sleep

(and, yep—many of these things happened to me. Great 👍)

Can KSM-66 Ashwagandha improve testosterone?

Since 2022, at least 5 different studies have shown a strong connection between KSM-66 Ashwagandha and improved testosterone. Effects observed in clinical studies have included:

Increased sexual drive and arousal
Higher reported levels of energy
Improved sperm concentration
Improved emotional wellbeing
Better social functioning
Decreased fatigue

According to some research, KSM-66 Ashwagandha might help boost testosterone in at least 3 different ways. By:

Boosting DHEA levels (a hormone your body uses to help make testosterone)
Reducing cortisol (that’s your stress hormone)
Supporting better sleep

Here’s more on point 3:

Some horrible facts on sleep

Only 15% of people sleep the recommended amount. And of those 15%, most probably aren’t getting high-quality sleep.
Sleep deprivation is linked to: a weakened immune system, worse cognitive performance, and increased chances of both heart disease and some cancers.
The modern world isn’t built for good sleep: we eat late, most people don’t have fixed sleeping patterns, many people work nightshifts, we’re all very stressed and anxious, and artificial light ruins our rest.

(by the way, here are some tips on how I’ve improved my sleep).

Anyway—if you aren’t sleeping properly (like the vast majority of us), you’re jeopardizing your physical and mental health, your long-term happiness, and your quality of life.

💪 And this part is especially important: most testosterone is produced DURING sleep. So: if you’re 35+ AND getting bad sleep, your testosterone is being negatively affected in more ways than one.

Can KSM-66 Ashwagandha improve sleep?

According to 7 recent studies, KSM-66 Ashwagandha might be able to:

Improve overall sleep quality
Help you fall asleep quicker
Increase total sleep time
Boost mental alertness
Reduce wake events
Reduce anxiety

… and unlike ‘normal’ sleeping pills, KSM-66 Ashwagandha promotes real natural rest (rather than just knocking you out).

Whatever the studies might say, KSM-66 Ashwagandha has definitely helped me sleep better. I’m not a doctor, but it might do the same for you.

⚠️ Most Ashwagandha isn’t KSM-66 Ashwagandha

Here’s the bad news: not all Ashwagandha is the same Ashwagandha (and even though I’m the co-founder of a supplement company, it took me way too long to work that out).

Much of the stuff on the market is:

Cheap
Less potent
Extracted with heavy chemicals
Made from leaves instead of roots

KSM-66, on the other hand, is:

The most bioavailable form—so you body absorbs and uses it properly
Made from only the root (that’s the traditional, medicinal part)
Extracted in a natural, chemical-free way

Basically, if you don’t know where your Ashwagandha is from and how it was extracted, you might just be wasting your money.

So, our ULTIMATE PLUS+ Power Pack uses ONLY KSM-66 Ashwagandha. This Power Pack is a bundle of two different supplements, which my wife and I developed over many years. Those two supplements are:

PERFORMANCE: a testosterone-supporting complex featuring Vitamin D, Maca Root, Zinc, Selenium, Fenugreek, L-Arginine, and Carnitine, it’s boosted my sex drive, muscle mass, strength, energy, and mood.
EQUILIBRIUM: this stress and sleep complex features L-Theanine, Lemon Balm, Magnesium Bisglycinate, Chamomile Extract, Hops Extract, L-Ornithine HCL, and KSM-66 Ashwagandha. It’s made both my wife and I much more alert and energetic—and the KSM-66 Ashwagandha has been great for my testosterone levels.

Testosterone, sleep, and KSM-66 Ashwagandha: final thoughts

That’s everything you need to know about testosterone, sleep, and KSM-66 Ashwagandha.

In short, the 5 main points here are:

Most Ashwagandha you buy isn’t KSM-66 Ashwagandha
KSM-66 is the best and most concentrated form you can get
KSM-66 Ashwagandha might improve your sleep and testosterone
(and improving your sleep can boost your testosterone even further!)
With the ULTIMATE PLUS+ Power Pack, you get both PERFORMANCE and EQUILIBRIUM. This 14-ingredient combo has improved my sleep, reduced my stress, and boosted my testosterone. Not bad!

P.S., a quick disclaimer: KSM-66 Ashwagandha is the most clinically-studied form of Ashwagandha worldwide. Taking supplements containing Ashwagandha should not be used as a substitute for a healthy and varied diet and lifestyle.
