  • Sparkling Hydration. Crafted with naturally-occurring electrolytes to hydrate you and keep your body firing on all cylinders. Fit Soda is more than a replacement for soda or soft drink alternative. 


  • Benefits with Bubbles. Fortified with branched-chain amino acids (BCAAs) to rebuild muscle after a hard workout. Your body uses amino acids to make proteins, which are the building blocks of every cell, tissue, and organ. Amino acids also play a crucial role in metabolism. 


  • All the flavor, none of the guilt. No artificial colors, flavors, or preservatives. Sugar-free and 0 calories without being boring. It’s caffeine-free so you can hydrate anytime, even before bed. This soft drink alternative is vegan/vegetarian, keto-friendly, and tastes like you’re being naughty but you’re not.


  • Have Your Cake and Drink it too. Created to hydrate, replenish, build, and repair without compromising on nostalgia or flavor. All these benefits in one healthy soda substitute!

Fit Soda was created with one thing in mind. How can we keep our bodies healthy and fully enjoy the process? A functional beverage designed to deliver nutrients to the body but taste like a soda. Kick sugar and keep your sanity.

Work and life are really hard sometimes. That’s why we created Fit Soda with BCAA's, so you could indulge and get healthy at the same time.  Fit Soda™ is sugar-free, and it consists of naturally-occurring electrolytes. It is also infused with branched-chain amino acids (“BCAA”). The term “branched-chain” refers to the chemical structure of BCAAs, which are found in protein-rich foods such as eggs, meat, and dairy products. 

Healthy enough to leap tall buildings in a single bound. Why can’t we have our cake and have it make us healthier too! That’s the world we believe in, and the vision we are chasing!

What people are saying

Kbev Rocks!

Love the flavor! Been drinking for a month and my memory has definitely improved. I’m remembering codes and clients names that I usually have a hard time remembering. Best of all I don’t have to force or remember to take it like my other supplements cuz its just like me drinking my coconut water or vitamin water. I’ve tried all the other flavors and blood orange and pear guava is my favorite!

Pear Guava

Thank you Koios…I’ve been looking for a way to kick my Red Bull habit…now I’ve found it. No more caffeine jitterers , sugar crash or guilt for what I’ve been doing to my body anymore. The mental sharpness and healthy feeling all around surprised me as I thought my diet was fairly healthy …Red Bull not withstanding… Love the Pear Guava

Other great flavors available

Both flavors available on Walmart taste awesome. Other flavors available that taste great are my personal favorite Apricot Vanilla, and Berry Genius. This is a great functional beverage that has replaced my morning coffee. I keep three flavors available in the fridge and rotate daily. I find myself craving a can mid-afternoon which really powers me through the rest of the day.

Good Energy drink substitute with good taste

I’ve had an energy drink dependency for many years now, and I would drink 2-3 monsters a day. My friend suggested this and I was skeptical, but I have been drinking it for 2 weeks and have not touched a monster since. It is more expensive(Which made me not want to buy it at first), but I feel more awake or focused for the whole day since I do not crash like i would after I drank a monster, and the ingrediants seem to be healthier(or even beneficial to make me focus more). I also like the taste(or I would stop buying it)

Fantastic clean energy boost for the brain!

I took a leap on trying this and I am glad I did! The product does exactly as advertised. It has a clean delicious taste and I could feel the effect within minutes! I was more focused and my concentration was improved and best of all… no crash after! Highly recommend!

Koios All Natural Energy Drink

I’ve tried peach mango which I love and pear Guava, which is also good. It definitely gives you energy but a clean and smooth energy. The taste is good and Ilook forward to that refreshing energy boost in the morning as soon as I wake up. I also like the fact it’s only 20 calories, plus MCT oil helps with clean energy and for helping me get my healthy fats for my keto weight loss diet. I will be trying more Flavours soon.

Great nootropic stack!

I used to make my own nootropic stack, but then I found Koios. The stack that I found works the best for me was similar to that in Koios and tastes much better. Highly recommended for productivity!

The future of functionality

Our blend of ingredients is acquired only from the best sources to deliver you a product that is safe, beneficial, and highly nutritional.

You only get one brain, so care for the one you have

The ingredients in KOIOS benefit both the brain and body. With each sip of KOIOS, your brain and body are provided with the essential nutrients it needs to strive and perform.

Improve attention and mental capacity

The ingredients in KOIOS work harmoniously together to support enhanced brain function by increasing attention, mental capacity, memory, and cognition.

A healthy dose of vitamins and herbs

Over 2,000mg of active ingredients specifically formulated to help drive your brain and body to the next level of performance.

Koios has an incredible effect on our brain function, as proven by clinical brain scans

Before Koios

We have clinically tested KOIOS beverages using state of the art neurofeedback brain imaging. qEEG, or brain mapping, uses sensors to measure the electrical activity within our client’s brain. This allows us to see a baseline assessment unique to each client. With this information, we can usually see the root of any symptom or challenge they may be facing in their day-to-day life.


After Koios

When comparing the general summary information figures 1 and 2, there are three main components that are noted. The first being a decrease in slow activity (delta and theta). For many, a decrease in slow activity can lead to quicker thought processes, better energy, sharper focus and an overall sense of mental clarity. The second finding is the increase in alpha. An increase in alpha will be important for many people as it is the brainwave responsible for homeostasis (an idling rhythm, or state of “normal”). In faster states of alpha, it is also associated with a peak alpha frequency (this will be discussed later) which can be linked with overall intelligence. The third finding is the increase in fast activity (beta and high beta). This brainwave is needed to feel alert, focused, and motivated. Seeing an increase in this brainwave could have many implications relating to the overall drive and energy of a person that might lack beta and is a very positive finding.
