Have you considered Armodafinil? It may be better than modafanil.

    David Tomen
    June 11, 2024

    Nad, Armodafinil is a derivative of Modafinil with a longer half life. So its effects should last longer. But my doctor prescribed Modafinil so that is what I use. And it works for me.

Hi David, I am a life time stutterer and I’ve read that recent research shows that part of the stuttering puzzle is excessive dopamine in the speech centers of the brain. The thinking is that the excessive dopamine over excites the speech centers and interrupts the signals that control speech. Drugs that tone down dopamine have as a side effect more fluent speech. The problem is that side effects of those drugs are unpleasant and people cannot tolerate taking the drugs for very long. The search is for a drug that targets the dopamine in the speech centers of the brain but has limited side effects. in the mean time I have been trying various nootropics hoping I might come upon something that will help my speech. I have tried a number of herbs and vitamins on the nootropics list but have not found success. I am hesitant about taking the Racetams. If excessive dopamine is the problem, can you point out the nootropics that may limit dopamine? Or the nootropics that improve fluency? Thanks

    David Tomen

    Greg, Aniracetam, CDP-Choline, L-Theanine, Phosphatidylserine (PS), Piracetam, and Uridine Monophosphate have all been shown to help assist verbal fluency.

      David im taking pregabalin for depression and make wonders, however i feel after 3 years a lack of energy
      and motivation ,how i can repare my Gabaergic sistem or how i can supply instead of pregabalin to motivation and depression

        David Tomen
        May 10, 2024

        Roberto, pregabalin is an inhibitor of a subunit of specific voltage-gated calcium channels. Which in turn prevents the release of most of your major neurotransmitters. I am not aware of any nootropic that works the same way. Your lack of energy and motivation is because this drug prevents the release of dopamine and norepinephrine.

        Stopping the use of this drug is the only way to restore your energy and motivation. Which I do NOT recommend. And not qualified to recommend.

Hi David,

Hope you are well. Will taking NAC long term blunt our body’s ability to produce glutathione?

In addition, can NAC be taken together with other supplements that support biological hormesis (e.g., Sulforaphane)? I’ve read that NAC might cancel out other supplements’ effect given that it activates NRF2 indirectly as a precursor to Glutathione, whilst Sulforaphane activate NRF2 through generating minor ROS.

    David Tomen
    April 25, 2024

    I use both and have never had a problem. NAC just like any other supplement will provide whatever benefits it offers if your body and/or diet cannot provide those nutrients. They do not ‘blunt’ your natural ability to produce what your body needs.

Can lithium orotate be taken in conjunction with Abilify or other antipsychotic medications safely?

    David Tomen
    April 24, 2024

    Mona, you’ll need to ask your doctor this question. Lithium Orotate is a very low dose of lithium. Nothing like the Lithium Carbonate that psychiatrists prescribe.

I have been reading about the positive cognitive effects of Dihexa. It should be safe given that it is just a peptide (amino acids). Do you have any thoughts on it? Thanks.

    David Tomen
    April 24, 2024

    Joseph, Dihexa is an experimental drug with very few clinical studies to show if it is safe or not safe to use. I would personally not use it.

April 21, 2024

My dear David, I want to thank you from the bottom of my heart because through your information I was able to get out of the quagmire I was stuck in….for years.
Since the brain chapter has been covered enough by you, think if you could with all the knowledge you already have, go a little further on the subject of Health.
I believe that the Father of Medicine Hippocrates spoke about the health of the Digestive System and not just the gut. The digestive system starts from the mouth, so that’s where we have to focus for the beginning on the Health journey. Looking for evidence I discovered that many amino acids (which you have already mentioned and are well aware of) are involved in good oral health which is not widely known. Think about whether you want to take this matter further.
Also another thought of mine is to have some space on your site that would be dedicated to the experiences of your readers regarding some substances that may have helped them without you being responsible for what will be mentioned there, just anyone who wants to look for it more and to have a discussion.
These are my thoughts.
Thanks again for the help I received from you. I am truly grateful.

    David Tomen
    April 22, 2024

    Nina, thanks for the suggestion. But in about 6 weeks or so I’ll be launching a closed community for anyone who is interested in sharing their experience. More on this in the next couple of weeks.

      April 25, 2024

      Great news!! I’m waiting for….

April 19, 2024

Hi David, just wondering how to gain access to the Head First first edition again? I bought the eBook but my laptop has stopped working which had it saved. I’ve looked through my emails and can’t locate it…
Also, do you have it in book format yet or is it still only eBook?


    David Tomen
    April 19, 2024

    Will, Head First 1st Edition is no longer available. If you send me an email I can email you a PDF. But you are better off getting Head First 2nd Edition. Its more complete at 962 pages. And is available on Amazon for a very reasonable price. Or get the Hard Cover or paperback which should arrive in a couple of days. https://geni.us/K1Bv

Hi David, I have a question regarding Uridine Monophosphate and Gotu Kola. From what I’ve read and Understand about Uridine is that Uridine improves Neuroplasticity. Gotu Kola increases the Dendrite’s length and connection to other Neurons. If this is the case then what is the Difference between the two Supplements with regard to their Action in the Brain and Contribution to Cognitive function?

    David Tomen
    April 19, 2024

    Larry, Uridine Monophosphate is natural and is a pyrimidine nucleoside that is one of 4 components that make up RNA (ribonucleic acid) in your body and brain. Gotu Kola is an herb.
