Does what it says on the tin, good flavour too
Tastes good, dissolves/mixes well, cheaper than premade bottles of electrolyte drink, but does the exact same thing. Great hydration, great pumps, great consistent energy. I drink one an hour before training and one whilst I train. I know its not marketed as a 'pump' product, but when you have a good electrolyte and hydration level, you get great pumps when you train. Only tried the Berry flavour which is nice. Actually much nicer than other brands I have tried. Generally electrolyte drinks that arent just packed with sugar, can be a little salty, which doesnt particularly bother me, but this one is mild, and quite palatable. Would highly recommend.

Great Boost for Hydration and Energy!
These electrolyte tablets have been a game-changer, especially during hot weather, workouts, or long days on the go. They dissolve quickly, taste great (without being too sweet), and really help with hydration and energy levels. I’ve noticed a big difference in how I feel after taking them — less fatigue and no headaches after exercise or travel. They’re also super convenient to carry around. Excellent value and a must-have for staying refreshed and balanced!

Works well, flavour is just okay
These electrolyte tablets do exactly what they’re supposed to — keep you hydrated during long workouts. They dissolve easily in water and the effect on hydration is noticeable.The flavour is fine but not amazing — I wouldn’t call it bad, just nothing to write home about. Overall, they’re effective and convenient, and I’ll keep using them for training sessions.

Mixed opinions
I have a mother with dementia and she forgets to drink. Thought I would try this to see if it helped with her memory, energy and hydration.Within 4 hrs of the first drink, mum was much more alert, chatting and joking. Much more like her old self.Unfortunately the next day she had an upset stomach. Very untidy! So I had mixed opinions if this is good or not.I then decided to try it for myself to see how it affected me. You dissolve the tablet in 500ml of water, then drink it all. The taste was good, although a bit bitter towards the bottom of the glass where it hadn't dissolved completely. It didn't seem to reduce my muscle pains or cramps. The next day I too had an upset stomach.Perhaps this product is good for sportspeople when they are exercising hard, or perhaps occasionally for those with dementia to give them a boost (and a clear out!) but for me it's not for everyday use.

The best electrolytes
The best tasting sugar free electrolytes on the market. I am doing Mounjaro and fasting for maximum health benefits, re-setting my body completely via Dr Berg. You can't do either one of those things without electrolytes. I am not a fan of overly sweet tasting things and have tried at least 4 other brands and these i actually really enjoy to the point I miss them when just drinking water. My go to is Berry flavour.
