The revolutionary sleep secret that sharpens your memory, too

You’d be hard pressed to find a more dangerous drug than sleeping pills. In fact, one recent study linked the popular sleep aid Ambien (and others like it) to a fivefold increase in risk of death.

That means sleeping pills could contribute to 500,000 “excess deaths” per year. And let’s not forget that they’re ridiculously addictive. How they’re still even on the market is beyond me.

But still, insomnia is a real issue, and anyone who has ever suffered from it can understand the desperation that drives people to take risky drugs. That’s why I was so thrilled to bring you news of a new cutting-edge supplement called ETAS™ last June.

ETAS is an extract from asparagus stems that have been treated with enzymes. It works by tapping into molecules called heat shock proteins (HSPs).

These molecules are what makes you feel relaxed and soothed after spending time in the heat of a bath or sauna. Your body releases them in response to heat (and other potentially harmful environmental factors) in order to protect and repair damaged proteins.

Unfortunately, the body’s supply of HSPs isn’t limitless, and your natural stockpile declines as you age. This is where ETAS comes in. It contains compounds that trigger the body to release a powerful form of HSP.

In other words, ETAS boosts the body’s supply of HSPs, unleashing the relaxing, sleep-promoting, anti-aging benefits they provide.

Hot off the presses 

When I last told you about ETAS, some impressive studies had already been published, but I was on the edge of my seat waiting for the results of one large and well-designed study that was still in the works. Well that study has finally been published, and it turns out that I had every reason to be hopeful.

The previously published studies—including lab studies and ones in human subjects—showed that ETAS didn’t just enhance HSP release, it also helped control the stress response in other ways.

First, it decreased levels of two key stress hormones, chromogranin A and cortisol. And second, it improved the autonomic nervous system’s response to stress.

And because stress is a sleep-killer, both of these effects help promote restful, restorative, care-free sleep.

The new study built on this previous research—and took it a step further by investigating how ETAS affects psychological stress when taken for longer periods of time. The double-blind, placebo-controlled study included 25 participants who took 150 mg of ETAS per day for 28 days.

The researchers wanted to verify that ETAS has the effects on the autonomic nervous system seen in previous studies. To do that, they measured how participants reacted to mental stress.

Beyond that, they wanted to determine whether ETAS could cut psychological stress markers like fatigue and poor mood. They measured that with a psychology questionnaire that looks at six different measures of emotional wellbeing.

The results were impressive…and they showed that ETAS appears to squash stress in more ways than originally thought.

After 28 days of taking the supplement, participants reported feeling less tired and “heavy.” (If you’ve ever struggled under the weight of chronic stress and poor sleep, you can probably relate to that description.) ETAS also made it easier for people to get out of bed in the morning, which suggests it improved sleep quality. Again, ETAS is proving to be key to that deep, restorative sleep we all need.

Second, ETAS counteracted the harm stress does to the immune system by bolstering secretory immunoglobulin A (sIgA) levels. SIgA is the body’s first line of defense against foreign invaders. It is secreted in all mucosal surfaces, including the mouth, nose, throat, eyes, and digestive system. In other words, the key entry points for viruses, allergens, and bacteria.

Protecting mucosal surfaces is essential for a healthy immune system. But when we’re stressed, we stop producing as much sIgA as we need. Which explains why when we’re stressed, we seem to catch every bug going around.

But this study showed that ETAS can help keep the immune system operating at peak performance, even when you’re under stress.

Not only that, but ETAS helped with the actual performance of those mental tasks as well.

Meaning that mentally and psychologically, stress just didn’t have the same negative effects on people when they were taking the supplement as it did when they weren’t.

Of course, it makes perfect sense that ETAS sharpens memory and mental function. I’ve told you before that to protect your brain—and your memory—adequate restful sleep is non-negotiable.

It’s during the deep stages of sleep that the brain processes newly acquired information and turns it into memories.

All the benefits, none of the risk

So to recap, this singular study showed that ETAS:

  • improves feelings of fatigue and “heaviness”
  • improves sleep quality
  • boosts the immune system
  • sharpens brain function

And, perhaps the best part? It does all of this safely. In fact, ETAS has been proven safe time and again—in stark contrast to Big Pharma’s sleep aids.
