(We already saw that too much iodine could poison both adults and children, and of course too little does not help much - iodine would seem to follow a U-curve like most supplements.) The listed doses at iherb.com often are ridiculously large: 10-50mg! These are doses that seems to actually be dangerous for long-term consumption, and I believe these are doses that are designed to completely suffocate the thyroid gland and prevent it from absorbing any more iodine - which is useful as a short-term radioactive fallout prophylactic, but quite useless from a supplementation standpoint. Fortunately, there are available doses at Fitzgerald 2012’s exact dose, which is roughly the daily RDA: 0.15mg. Even the contrarian materials seem to focus on a modest doubling or tripling of the existing RDA, so the range seems relatively narrow. I’m fairly confident I won’t overshoot if I go with 0.15-1mg, so let’s call this 90%.
With this experiment, I broke from the previous methodology, taking the remaining and final half Nuvigil at midnight. I am behind on work and could use a full night to catch up. By 8 AM, I am as usual impressed by the Nuvigil - with Modalert or something, I generally start to feel down by mid-morning, but with Nuvigil, I feel pretty much as I did at 1 AM. Sleep: 9:51/9:15/8:27
These brain enhancers allow users to go without sleep for extended periods of time. But in the long-term, insomnia is a hazardous side effect, not a so-called benefit. Lack of sleep is extremely detrimental to your brain health and function. It’s during sleep that your brain consolidates memories, cleans away toxins, repairs itself, and creates new brain cells. (52, 53, 54, 55)

The exact moment when science morphed into science fiction was when so-called climate scientists (formerly known as weather forecasters) realised that some people could be conned into believing in man-made global warming and pumping fortunes into university departments to prove it. Now, they're all at it.Come back Arthur C Clarke. Your country needs you now.
For now, instead of reaching for a designer supplement, you're better off taking a multivitamin, according to some experts. It's well known that antioxidants like vitamins C and E protect cells from damage by disarming free radicals. Brain cells are especially vulnerable to these troublemakers because the brain generates more free radicals per gram of tissue than any other organ. Antioxidants also protect neurons by keeping blood vessels supple and open, ensuring the flow of nutrients to the brain.
I ultimately mixed it in with the 3kg of piracetam and included it in that batch of pills. I mixed it very thoroughly, one ingredient at a time, so I’m not very worried about hot spots. But if you are, one clever way to get accurate caffeine measurements is to measure out a large quantity & dissolve it since it’s easier to measure water than powder, and dissolving guarantees even distribution. This can be important because caffeine is, like nicotine, an alkaloid poison which - the dose makes the poison - can kill in high doses, and concentrated powder makes it easy to take too much, as one inept Englishman discovered the hard way. (This dissolving trick is applicable to anything else that dissolves nicely.)
Tempted to skip breakfast? Studies have found that eating breakfast may improve short-term memory and attention. Students who eat it tend to perform better than those who don’t. Foods at the top of researchers' brain-fuel list include high-fiber whole grains, dairy, and fruits. Just don't overeat; researchers also found high-calorie breakfasts appear to hinder concentration.

"Over the years, I have learned so much from the work of Dr. Mosconi, whose accomplished credentials spanning both neuroscience and nutrition are wholly unique. This book represents the first time her studies on the interaction between food and long-term cognitive function reach a general audience. Dr. Mosconi always makes the point that we would eat differently and treat our brains better if only we could see what we are doing to them. From the lab to the kitchen, this is extremely valuable and urgent advice, complete with recommendations that any one of us can take."
Here’s how it works: Donepezil boosts serotonin and acetylcholine in the brain, chemicals that are usually found in high concentrations in the brains of young children which naturally decrease with age. As a cholinesterase inhibitor, Donezepil boosts brain function by increasing the amount of acetylcholine around nerve endings. In dementia and Alzheimer’s patients, the drug has been shown to improve memory function.

Even the best of today’s nootropics only just barely scratch the surface. You might say that we are in the “Nokia 1100” phase of taking nootropics, and as better tools and more data come along, the leading thinkers in the space see a powerful future. For example, they are already beginning to look past biochemistry to the epigenome. Not only is the epigenome the code that runs much of your native biochemistry, we now know that experiences in life can be recorded in your epigenome and then passed onto future generations. There is every reason to believe that you are currently running epigenetic code that you inherited from your great-grandmother’s life experiences. And there is every reason to believe that the epigenome can be hacked – that the nootropics of the future can not only support and enhance our biochemistry, but can permanently change the epigenetic code that drives that biochemistry and that we pass onto our children.
Barbara Sahakian, a neuroscientist at Cambridge University, doesn’t dismiss the possibility of nootropics to enhance cognitive function in healthy people. She would like to see society think about what might be considered acceptable use and where it draws the line – for example, young people whose brains are still developing. But she also points out a big problem: long-term safety studies in healthy people have never been done. Most efficacy studies have only been short-term. “Proving safety and efficacy is needed,” she says.
At dose #9, I’ve decided to give up on kratom. It is possible that it is helping me in some way that careful testing (eg. dual n-back over weeks) would reveal, but I don’t have a strong belief that kratom would help me (I seem to benefit more from stimulants, and I’m not clear on how an opiate-bearer like kratom could stimulate me). So I have no reason to do careful testing. Oh well.
Hericium erinaceus (Examine.com) was recommended strongly by several on the ImmInst.org forums for its long-term benefits to learning, apparently linked to Nerve growth factor. Highly speculative stuff, and it’s unclear whether the mushroom powder I bought was the right form to take (ImmInst.org discussions seem to universally assume one is taking an alcohol or hotwater extract). It tasted nice, though, and I mixed it into my sleeping pills (which contain melatonin & tryptophan). I’ll probably never know whether the $30 for 0.5lb was well-spent or not.

After a month of testing nootropics, I’m not ready to commit to them permanently. They’re simply too untested, and while “move fast and break things” might be a good approach to building software, it’s not what I want for my brain. Still, I think we’ll likely hear more about nootropics, especially as recreational users of more powerful prescription drugs like Adderall and modafinil look for less harsh alternatives. Sometimes, when you’re working, you don’t want to put your brain on jet fuel—a little unleaded gas will do. And for those moments, nootropics could be a fertile testing ground for the intrepid body-hacker.
Reason: Acetyl-L-carnitine can protect the brain from neurotoxicity. It can also ward off oxygen deprivation. Acetyl-L-carnitine can even preserve cells energy-producing mitochondria. Plus, it can rejuvenate mental and physical function. Dosages for studies have been in the 1,500 – 4,000 mg range. These are divided into two or three doses. However, we recommend no more than 1,000 mg of acetyl-L-carnitine a day without medical supervision.
