Nootropics are supplements that are said to improve brain function, focus, and energy. Many people have probably wondered about them, but not enough people have given a fair shake. I’ve tried many nootropics myself in the past, but Koios is one of the best I’ve had yet.


Koios possesses several ingredients that are designed to assist the brain in working optimally. The formula supports neurotransmitters and their release, metabolism (especially brain metabolism), and even some of the physical components of the brain. When combined, these ingredients should be great for brain health and may make a difference in how your brain works, such your ability to focus on a task or your sleep quality.


Here is a list of some of the ingredients in Koios:


  • B6 and B12: B6 is involved in the production of several key neurotransmitters, and B12 is well known for its role in energizing the brain. Together they form a great mental cocktail.
  • Alpha GPC: Alpha GPC is a kind of choline and a precursor to the neurotransmitter acetylcholine. Acetylcholine is involved in wakefulness and focus, and has also given me some interesting dreams.
  • Tyrosine: An amino acid precursor to the catecholamines, which include dopamine and the adrenals, tyrosine is involved in motivation and energy. 
  • Guarana: There’s 200mg of guarana extract in Koios, which means there is caffeine in this nootropic. I checked with the company and was informed that the extract amounts to roughly 90mg of caffeine per serving. That’s about as much as a small coffee. Caffeine stimulates the release of the above mentioned catecholamines. I put this in the cons section because some people may not want more caffeine, but there’s a benefit to this as well, which I will discuss below.
  • Phosphatidylserine: Phosphatidylserine is a kind of lipid called a phospholipid that is found in high quantities in cell membranes. This lipid is particularly concentrated in the brain, and it is believed that more can assist with memory and cognition.
  • Various herbs: The formula also includes numerous herbs and herbal extracts believed to assist in mental function, energy, immunity, metabolism, and neurotransmission. These extracts include vinpocetine, bacopa, and a few others.


Koios is not a drug, so you won’t get powerful drug-like effects, but I definitely noticed a difference when taking it. As a writer I’m often required to sit for long periods at odd hours of the morning or night, or in conditions where distractions abound. Because of my greater-than-average need to focus and perform mental tasks, I feel as though I noticed improved focus while taking Koios.


Don’t consider Koios for just its nootropic effects either. If you're looking to get away from the calories or artificial sweeteners of energizing and caffeinated drinks and pre-workout beverages, Koios might be a good alternative. Because it’s a pill instead of a beverage, it might be exactly what you’re looking for and may give you just the morning boost or pre-workout kick in energy and focus you need, with more nutrition and lower cost than many alternatives. If you’re still not sure if you want to commit to a full bottle, Koios offers a trial pack for you to give it a shot without making the larger purchase.


Nootropics have always been interesting to me, but not every formula I’ve tried is as strong as Koios. If you’ve been interested in this type of supplement, this is a good one to check out.
