Very good electrolyte tab
These are very very good electrolyte tablets. You really feel the caffeine hit and the taste is pretty good. I prefer the taste to the SiS equivalent but that is personal preference. These ones do have a very slight sucralose taste (sweetener) but its not bad by any means.This tablet is probably best suited to someone doing short length exercise and who is using cardio exercise to aid weight loss. If you are doing endurance sport I do not see the point in a 'Zero' branded sports drink, especially now that the general trend is towards 100g/carb per hour. You can achieve this using High5's other sports drink, which is their carb mix 2:1 Energy Drink.Still, this is a great product which will keep you hydrated, prevent cramp and give you a slight kick. I normally use two tabs per bottle.

Great taste and great for hydration
I wanted something that will help my hydration on a day to day basis as I often get dehydrated due to long shifts at work and other medical issues. These seem to be doing the job well, they taste nice and I do feel better for having one a day. They’re really easy to pop in a water bottle or in a normal glass of water. The colour is maybe a little off putting but the taste is great. I got these while they were on offer and overall I feel they’re great value for money. I love the peace of mind that I’ve made a positive step towards my hydration and general health each day.

Reasonably nice taste with a caffeine kick
Reasonably nice taste when added to a small bottle of water (500ml). Takes a couple of minutes to dissolve although a small amount of powder residue is left at the bottom. Have been taking every day for some time although I'm not sure how effective they are. Definately can taste the caffeine in these for an instant energy boost. Has a slight Red Bull kind of taste.

Very good will purchase again
Bought these as a supplement when intermittent fasting. Chose these mainly for the caffeine content as with intermittent fasting I wouldn’t be consuming coffee and needed something to ease the caffeine withdrawal headaches. These worked brilliantly for me. The taste isn’t great at first can taste a bit salty on the first few sips but gets better. Definitely better taken with ice cold water.

Good if you filter drinking water.
I filter my water and was warned by a doctor that although it removes unwanted 'bits' it also removes some good particles. I was advised my potassium levels were low, probably due to filtering my water. So I bought these to ensure,y levels are now normal. They taste great and add a slight tang Ines to my drink which is really enjoyable. I definitely recommend them

The product is fine. But not a hydration drink.
You know, this product has sort of a mild taste. I wouldn't say it's unpalatable, but also it doesn't really taste amazing. It's the sort of thing that you could I could bear to drink If I need the caffeine.And to be fair, it does have zero sugar. So yes, you can't add this into a drink and so we'll get a caffeinated drink that is somewhat healthy. But in my opinion, it does say it's an electrolyte sports drink and there's just not enough electrolytes in this.One dose will only give you 3.5% of your daily recommended amount of potassium. If you compare this with something like Power Raid, which is an isotonic sports drink, then it's clear to see that this doesn't, this isn't really enough potassium. And for those that don't know, intra cell hydration is mainly a product of sodium potassium pumps. So I don't know, maybe I'm wrong on this, but I think it could do with a little bit more potassium in there. 3.5% is not that much. The ratio should be closer 2:1 sodium to potassium. So either way, there's too much salt and not enough potassium.So would I buy this again? Ah, I'm on the fence. You know, the caffeine that you get from it is good and the taste is okay, not great. But at the same time, it is a little bit salty. Also, it doesn't really taste of berries or like a light peach flavour. I don't mind it too much. I'll see if I continue with it.

Theyre not terrible just tastes weird
They test like a watered down, none fizzy redbull to me haha - that being said, they’re alright for the cost :)
