The flavor, packaging, and ingredients have recently changed. In my opinion, the red fruit flavor and the packaging have taken a turn for the worse. But the biggest problem is that (according to estimates) 5–10% simply doesn’t dissolve in water.

The updated flavor with the red fruit has gone way back. Also, the powder does not dissolve as well, always leaves a bottom at the bottom of the water bottle no matter how well ge shakes.
BYE! was always my go to brand but now I don't know.

A regular user of the sports drink for several years now and came in contact with it during a bike show. Before that I always used other brands. The reason for switching to BYE was the conversation I had with the exhibitor at the time. I often had digestive problems with other brands, especially after cycling: an unpleasant feeling in the stomach and sometimes painful intestines. The natural composition got me thinking and attracted me. After the good conversation , including so about my complaints, bought a trial pack.
Since using it, I no longer suffer from anything, both during and after cycling. My body reacts very well. The sports drink does what it is supposed to do and a very additional advantage is the natural taste. I alternate flavors and have never had the idea of having had to deal with a chemical. This (delicious) experience makes me go for BYE!'s other products as well.
The only thing that might make it even better for me is if some form of tablets were also available. Especially on long trips, I now mess around with sachets of powder. It works, but especially in humid, hot weather it can be a hassle.
So for me, to date, no other brand.

After years of using an isotonic drink from a reputable brand, I wanted to try this product. After careful selection from the 1000 proposals on the market, the fact that it is natural and the nutritional properties described prompted me to try it. I tried it the product both in indoor and outdoor activities, my main discipline is mountain biking, I tried this product during intense workouts and workouts with a lot of sweating, I can say that it is an excellent supplement, it did not cause intestinal stomach problems, it turned out to be so an excellent ally for training. I recommend you to try it too. Regards Vincenzo D'Agrosa

I have had quite a few brands of isotonic drink but most of them had an aftertaste or a very strong taste so I had already given up hope .until I took a trial subscription to cycling that included this .I was pleasantly surprised with the delicious taste and that there is no aftertaste .so you see again that after years of searching you suddenly find the right one

During Ironman Maastricht, I came into contact with BYE. I liked it immediately. I have now used this drink as Isonotic and Hypotonic and like it very much! Taste is not too sweet or tasteless. Highly recommended!

Both flavors are very tasty, and definitely not too sweet. This will be different for everyone, but even on long intensive rides my body tolerates the BYE sports drinks without any problems. It's also less sticky than other sports drinks I've used and doesn't leave any color deposits in my water bottles. The packaging could be a bit more environmentally friendly, a large part of the jar now contains air. More powder per jar, or smaller jars would already be a solution. A measuring spoon as an option instead of the standard one in each jar is perhaps also an idea.

The Red fruit flavor is my absolute favorite hypotonic or isotonic drink during bike rides. Not too sweet.
Anton Cousins (verified owner) –
I got the Lemon flavored powder. Before ordering it I was a little worried that it would be too sweet for my taste, but this was not too bad. The taste is nice and familiar, and not too sweet. It falls well on the stomach.
I have used it as an isotonic sports drink. For example, I used it once during a 1.5 hour endurance run, with 19 degrees outside. It hydrated well and also gave me that little extra energy for the distance.
The ideal thing about the powder is also that you can use a little more or less according to taste. As the description says, you can also use it as a hypotonic sports drink (more for hydration than energy). Then you use a little less powder in proportion to water.
Natural really appeals to me, and after using an energy bar from BYE! during the Ironman 51.50 Westfriesland, I wanted to try the Isotonic Sportdrink for my longer endurance runs. I am satisfied with the product, and it is also easier than always making my own natural sports drinks.
