Huperzine A: A Natural Nootropic

Huperzine A is a natural compound that inhibits acetylcholinesterase, increasing acetylcholine levels. It has potential benefits for Alzheimer’s prevention and memory enhancement. Find it on Amazon.

Huperzine A: A Natural Nootropic

Huperzine A is a compound, specifically a naturally occurring sesquiterpene alkaloid, that functions as an acetylcholinesterase inhibitor. If that seems like a bunch of big words, don’t worry, we’ll translate in a moment.

First, a nod to its origins: it is found in certain kinds of firmoss, especially the “toothed clubmoss”, Huperzia serrata, which grows in many Asian countries.

What’s an acetylcholinesterase inhibitor?

Let’s do this step-by-step:

  • An acetylcholinesterase inhibitor is a compound that inhibits acetylcholinesterase.
  • Acetylcholinesterase is an enzyme that catalyzes (speeds up) the breakdown of acetylcholine.
  • Acetylcholine is a neurotransmitter; it’s an ester of acetic acid and choline.
    • This is the main neurotransmitter of the parasympathetic nervous system, and is also heavily involved in cognitive functions including memory and creative thinking.

What this means: if you take an acetylcholinesterase inhibitor like huperzine A, it will inhibit acetylcholinesterase, meaning you will have more acetylcholine to work with. That’s good.

What can I expect from it?

Huperzine A has been well-studied for a while, mostly for the prevention and treatment of Alzheimer’s disease:

However, research has suggested that huperzine A is much better as a prevention than a treatment:

❝A central event in the pathogenesis of Alzheimer’s disease (AD) is the accumulation of senile plaques composed of aggregated amyloid-β (Aβ) peptides.

Ex vivo electrophysiological experiments showed that 10 μM of Aβ1-40 significantly decreased the effect of the AChE inhibitor huperzine A on the synaptic potential parameters. ❞

In other words: the answer to the titular question is “Yes, yes it can”

And, to translate Dr. Zueva’s words into simple English:

  • People with Alzheimer’s have amyloid-β plaque in their brains
  • That plaque reduces the effectiveness of huperzine A

So, what if we take it in advance? That works much better:

❝Pre-treatment with [huperzine A] at concentrations of 50, 100, and 150 µg/mL completely inhibited the secretion of PGE2, TNF-α, IL-6, and IL-1β compared to post-treatment with [huperzine A].

This suggests that prophylactic treatment is better than post-inflammation treatment. ❞

As you may know, neuroinflammation is a big part of Alzheimer’s pathology, so we want to keep that down. The above research suggests we should do that sooner rather than later.

Aside from holding off dementia, can it improve memory now, too?

There’s been a lot less research done into this (medicine is generally more concerned with preventing/treating disease, than improving the health of healthy people), but there is some:

Huperzine-A capsules enhance memory and learning performance in 34 pairs of matched adolescent students

^This is a small (n=68) old (1999) study for which the full paper has mysteriously disappeared and we only get to see the abstract. It gave favorable results, though.

The effects of huperzine A and IDRA 21 on visual recognition memory in young macaques

^This, like most non-dementia research into HupA, is an animal study. But we chose to spotlight this one because, unlike most of the studies, it did not chemically lobotomize the animals first; they were and remained healthy. That said, huperzine A improved the memory scores most for the monkeys that performed worst without it initially.

  • Stop Cancer 20 Years Ago

    Dr. Jenn Simmons shares vital tips on preventing cancer and inflammation, advocating for lifestyle changes and proactive health management at any age.

    Get Abreast And Keep Abreast

    This is Dr. Jenn Simmons. Her specialization is integrative oncology, as she—then a breast cancer surgeon—got breast cancer, decided the system wasn’t nearly as good from the patients’ side of things as from the doctors’ side, and took to educate herself, and now others, on how things can be better.

    What does she want us to know?

    Start now

    If you have breast cancer, the best time to start adjusting your lifestyle might be 20 years ago, but the second-best time is now. We realize our readers with breast cancer (or a history thereof) probably have indeed started already—all strength to you.

    What this means for those of us without breast cancer (or a history therof) is: start now

    Even if you don’t have a genetic risk factor, even if there’s no history of it in your family, there’s just no reason not to start now.

    Start what, you ask? Taking away its roots. And how?

    Inflammation as the root of cancer

    To oversimplify: cancer occurs because an accidentally immortal cell replicates and replicates and replicates and takes any nearby resources to keep on going. While science doesn’t know all the details of how this happens, it is a factor of genetic mutation (itself a normal process, without which evolution would be impossible), something which in turn is accelerated by damage to the DNA. The damage to the DNA? That occurs (often as not) as a result of cellular oxidation. Cellular oxidation is far from the only genotoxic thing out there, and a lot of non-food “this thing causes cancer” warnings are usually about other kinds of genotoxicity. But cellular oxidation is a big one, and it’s one that we can fight vigorously with our lifestyle.

    Because cellular oxidation and inflammation go hand-in-hand, reducing one tends to reduce the other. That’s why so often you’ll see in our Research Review Monday features, a line that goes something like:

    “and now for those things that usually come together: antioxidant, anti-inflammatory, anticancer, and anti-aging”

    So, fight inflammation now, and have a reduced risk of a lot of other woes later.

    See: How to Prevent (or Reduce) Inflammation

    Don’t settle for “normal”

    People are told, correctly but not always helpfully, such things as:

    • It’s normal to have less energy at your age
    • It’s normal to have a weaker immune system at your age
    • It’s normal to be at a higher risk of diabetes, heart disease, etc

    …and many more. And these things are true! But that doesn’t mean we have to settle for them.

    We can be all the way over on the healthy end of the distribution curve. We can do that!

    (so can everyone else, given sufficient opportunity and resources, because health is not a zero-sum game)

    If we’re going to get a cancer diagnosis, then our 60s are the decade where we’re most likely to get it. Earlier than that and the risk is extant but lower; later than that and technically the risk increases, but we probably got it already in our 60s.

    So, if we be younger than 60, then now’s a good time to prepare to hit the ground running when we get there. And if we missed that chance, then again, the second-best time is now:

    See: Focusing On Health In Our Sixties

    Fast to live

    Of course, anything can happen to anyone at any age (alas), but this is about the benefits of living a fasting lifestyle—that is to say, not just fasting for a 4-week health kick or something, but making it one’s “new normal” and just continuing it for life.

    This doesn’t mean “never eat”, of course, but it does mean “practice intermittent fasting, if you can”—something that Dr. Simmons strongly advocates.

    See: Intermittent Fasting: We Sort The Science From The Hype

    While this calls back to the previous “fight inflammation”, it deserves its own mention here as a very specific way of fighting it.

    It’s never too late

    All of the advices that go before a cancer diagnosis, continue to stand afterwards too. There is no point of “well, I already have cancer, so what’s the harm in…?”

    The harm in it after a diagnosis will be the same as the harm before. When it comes to lifestyle, preventing a cancer and preventing it from spreading are very much the same thing, which is also the same as shrinking it. Basically, if it’s anticancer, it’s anticancer, no matter whether it’s before, during, or after.

    Dr. Simmons has seen too many patients get a diagnosis, and place their lives squarely in the hands of doctors, when doctors can only do so much.

    Instead, Dr. Simmons recommends taking charge of your health as best you are able, today and onwards, no matter what. And that means two things:

    1. Knowing stuff
    2. Doing stuff

    So it becomes our responsibility (and our lifeline) to educate ourselves, and take action accordingly.
