If you had to choose between pine bark extract or berberine for alzheimers and dementia treatment which one would you choose between the two? As first choice? Why?

    David Tomen
    December 26, 2019

    Cy, if I was dealing with Alzheimer’s and/or dementia I’d be using both of them. Because there is nothing scarier than getting either of those two diseases.

    you have not addressed taking Lion’s Mane if on Blood Pressure Meds

      David Tomen
      February 14, 2020

      Ernest, I’m not aware of any contraindication with blood pressure meds. Which is the reason why I didn’t address it. Lion’s Mane is considered non-toxic even at doses up 5 grms.

Hello there, thank you so much for your website. It has helped me a massive amount with informing myself on what I need to do to supplement my way off of some medications. I’m down one, and one more to go. And feeling so much better. Your website is so informative it’s the first place I go now before I look anything up on google.

I was just curious if you know anything about the Vitex agnus-castus (Chasteberry). I’ve very intrigued about it mostly as progesterone booster and I am a bit confused on whether it is a nootropic or not because I have read both ways.

I have previously been on progesterone and found it helped massively all round for me and I was just curious about Vitex and what you may know.

Thanks so much

    David Tomen
    December 15, 2019

    Denise, I’ve not reviewed Chasteberry because I believed it to be only for sex hormones. Turns out that it may be potent dopamine booster as well. But then again, the sex hormones are active in the human brain. I just haven’t gotten around to researching and writing that blog post yet.

      December 15, 2019

      No worries, I’ll keep my eye out. Thanks for the fast reply

      May i ask where is a good online vendor to buy good quality nootropics??. I feel the racetams dont really work for me ive tried piracetam but it only worked after a good jog or sometimes a walk and I am not sure if it is lack of blood flow to my brain.

December 10, 2019

Hello Mr. Tomen,
Thanks for the great content!
What do you think for the following stack?
Do you think there is a risk of desynthesizing dopamine receptors, would you add/remove anything and what dosages would you recommend.
L tyrosine(I cant find NALT in my country), L theanine, Coffeine


    David Tomen
    December 11, 2019

    Martin, this stack also requires the B-Vitamins as they will get depleted by using caffeine. And are required for the synthesis of dopamine. This stack should not desensitize dopamine receptors if you use recommended dosages. In fact, this is the same formulation created by Opti Nutra for their new Performance Lab Stim: https://nootropicsexpert.com/performance-lab-stim-review/

      Hello David,

      Can you specify your top 3 Nootropics for Peripheral Neuropathy ?(not diabetic neuropathy). Trying to help someone who has just started getting those symptoms.

      Thanks and regards,

        David Tomen
        December 19, 2019

        John, it entirely depends on the cause of this disease. And according to the Mayo Clinic it can be any number of things: https://www.mayoclinic.org/diseases-conditions/peripheral-neuropathy/symptoms-causes/syc-20352061. The B-Vitamins are critical for nerve health. And anything else to assist myelin synthesis. Do a search of Nootropics Expert for “myelin” and see what else turns up.

        December 21, 2019


        Thanks for the feedback. Will do as suggested.

        Happy Holidays! and Best Wishes for the New Year !!

Hi David
On L-theanine…everybody recommends 200mg 2-3 times a day…You recommend 600mg 2´3 times a day…for anxiety…..not too much?
I trust you…but will that make more calm or could you get too anxious possibly ?

    David Tomen
    December 6, 2019

    Michael, I’ve found over the years that “everybody” is one person puts a dosage on their blog and a dozen other sites copy it.

    Recommended dosage of L-Theanine is 200 – 400 mg once or twice per day. With a maximum of 1,200 mg per day according to the Cleveland Clinic (which is no longer available on their website).

    Those dosages are based on user experience and clinical studies.

Hi David,
question, do you take all these daily? I saw these in your video on “best nootropics 2019”
Acetyl-L-Carnitine (ALCAR)
Bacopa Monnieri
Lion’s Mane Mushroom
Lithium Orotate
N-Acetyl-L-Tyrosine (NALT)
Phosphatidylserine (PS)
Pine Bark Extract
Rhodiola Rosea
Vitamin B Complex

also, I have been taking
L theanine
bacoba extract
alpha GPC
lions mane
cordyceps sinesis
and occasionally like 3 days a week i will take adrafinil and maybe once a week phenylpiracetam. what do you think of my stack?

    David Tomen
    December 2, 2019

    Brian, yes I use everything on that list daily with the exception of Noopept. When I have it I use it.

    The way your stack is now it’ll boost BDNF, acetylcholine and some brain waves. It would be more balanced if you addressed some of the other things going on in your brain including the other major neurotransmitters.

    I suggest taking a look at this post for other ideas: https://nootropicsexpert.com/how-to-create-the-best-nootropic-stack/

Hello David!
I am wondering what you know about vitamin A as a nootropic!
I have been taking around 10mg pure retinyl acetate daily for the last 2 weeks and have noticed an incredible boost to attention and memory.
Can you tell me more about this powerful vitamin?

Thank you!

      Hello David,

      I wanted to hear what’s your thought on Pregnenolone.

      Studies show that it’s a powerful neurosteroid for brain so it can function at its best. I notice that many places don’t include it as a nootropics regime.

      I know just like Dhea it should be cycle on and off.

        David Tomen
        November 20, 2019

        Jim, haven’t done the research on Pregnenolone yet. And a full post on how ‘sex’ hormones affect the brain is at the top of my “to-do” list for Nootropics Expert.

        I know that each of them are involved in brain function but don’t know the details yet. So please standby and watch your email!

David, can training to become ambidextrous improve brain function? I didn’t find a conclusive answer.

    David Tomen
    November 17, 2019

    Jean, likely because there is no clear way to answer your question.

    The type of training you reference would need to “rewire” sections of the brain for it to be effective. Which includes neurogenesis, strengthening of synaptic connections, and increasing long-term potentiation for encoding the type of memory needed to recall the moves.

    So is that considered improving brain function? I suppose it would be considered that by those interested in becoming ambidextrous.

November 6, 2019

I am taking 10 mg of cipralex daily and on the occasion a .5 mg of clonazepam, and would like to start taking a nootropic (namely mind lab or something similar). Will this have any negative effects for mixing the two? I know to stay clear of 5-htp. Any advice would be great! Thanks

    David Tomen
    November 7, 2019

    Josh, cipralex works by increasing serotonin levels in your brain. And clonazepam works by increasing GABA. So you want to avoid any nootropic that increases either serotonin or GABA.

    Mind Lab Pro contains L-Theanine which increases both serotonin and GABA. So not a good idea to use MLP when using either of those drugs.

    I suggest you learn the mechanism of action of both drugs (Wikipedia is a good source). Then read and compare the ingredients of every nootropic you are considering. To see if there could be a problem.

      Angela Rodriguez
      November 11, 2019

      hello, i have a question. I am taking an antidepressant (citalopram 40mg) and i am also taking bupropion 300 mg xl. Plus i am taking levothyroxine for my thyroid, and lisiniprol for my blood pressure. Now i want to wean myself off of the anti”s, i know i need to speak to my doctor, and i have, and she just keeps pushing for me to stay on them. So i am taking my health and doing what i want to do and what i feel is best, and that is to get off of these antidepressants. In your opinion, what nootropics would you recommend to do this? i am not asking for medical information, just an opinion. thank you.

        David Tomen
        November 12, 2019

        Angela, this is a loaded question but here’s how I’d start if I were in your shoes.

        If the antidepressants you are using are beneficial then find out how they work in your brain. Wikipedia or medscape are good sources for this. Locate the drug, then look for the section called “Pharmacology” (i.e. https://reference.medscape.com/drug/celexa-citalopram-342958#10). For this drug it looks like it increases serotonin in your brain (i.e. Inhibits the reuptake of serotonin in presynaptic neurons).

        So if this drug works for you then raising serotonin is your goal when searching for a nootropic. The easiest way to increase serotonin is with its precursor L-Tryptophan.

        But you must be very careful about mixing nootropics with things like antidepressants. Because in this case increasing serotonin too much can easily cause Serotonin Syndrome. Which can be lethal. And I’m deadly serious about this. Don’t mess with this unless you are 100% confident in what you are doing. Please.

        That said, it’s possible to wean yourself off of certain meds and replace them with natural nootropic supplements. But it takes time, patience, and a lot of research and reading. And trial and error.
