I ran out of Numin: you don’t know what you’ve got until it’s gone

I ran out of Numin. So I did what most people do when the thing that's working disappears: I defaulted back to caffeine. More coffee in the morning, another cup at my desk by 11, another way past 3pm when the afternoon slump hit hard.

I'm an anxious person by nature, always have been. It's usually manageable, something I've learned to work with rather than around. But leaning on caffeine again, it wasn't manageable in the same way. I noticed the jitters before I noticed anything else, that faint tremor in my hands over a keyboard. Heart palpitations that make you feel like you’re on the verge of a heart attack. My sleep, which I’m usually pretty good at (😉) got shallower and more broken.

Being a scientist, rather than making myself feel bad about my recent reliance on caffeine, I wanted to understand and break it down, rather than just feeling.

Caffeine is a stimulant. It works by blocking adenosine, the molecule that builds up across your day and signals to your brain that it's tired. Block the receptor, and you don't feel tired, even though the underlying fatigue hasn't gone anywhere. It's a mask, not a fix. The adenosine keeps accumulating in the background, and depending on how your nervous system is wired, you also get the side effects of a stimulant sitting on top of an already-anxious baseline: the wired feeling, the jitters.

Numin doesn't work that way. It's stimulant-free. It isn't trying to hide a message that your brain is trying to receive. It's targeting the actual mechanisms behind decision fatigue.

That distinction matters more than it sounds like it should, because feeling sharp and performing well are not the same thing. A 2019 study on elite League of Legends players found that an energy drink made no measurable difference to their cognitive or physical performance compared to a placebo, despite the players getting the expected stimulant effect (Thomas et al., 2019). Feeling more alert doesn't mean your decision-making has actually improved. Sometimes it just means you feel more alert, and for me, that’s not always a good thing.

In Numin's clinical trial, the group taking the supplement showed an 11.25% relative improvement in decision-making accuracy under fatigue. That's not a stimulant effect but instead, it's the effects of fatigue being mitigated.

I didn't clock just how much Numin was doing for me until it wasn't there. I knew my workflow was improved but now I can clearly distinguish how. My focus held for longer blocks of work, I could hop on meetings late in the day and communicate my jumbled inner train of thought with clarity, I wasn't losing the thread as easily in the afternoon. I hadn't registered any of that as something Numin was actively doing, because I didn’t have that ‘alert’ jittery feeling. But it has been doing its job, day after day, until a week without it made the gap obvious.

This is my own experience, not a clinical claim like in our trial. But it's exactly the kind of thing you don't see until it's gone.

P.s. I’ll be getting my order in Asap.
