– HIGH5 ZERO Caffeine Hit ElectrolyteTablet - Hydration Tablets Enhanced with Vitamin C - 0 Calories & Sugar Free - Boost Hydration, Performance & Wellness - Berry, 20 Tablets (20x, Pack of 1)

I go to the gym regularly, and over time drinking plain water can get a bit boring, especially when you’re on a diet and trying to avoid extra calories. These tablets are a really convenient way to mix things up. You just drop one into your bottle and it turns plain water into a flavoured drink, which makes it much easier to stay hydrated during workouts. The taste is actually quite nicely (not too strong or overly sweet), and I like that there are different flavours to choose from, so it doesn’t get repetitive. They dissolve quickly and are easy to carry around in a gym bag, which is a big plus. I’ve been using these for quite a while now and keep coming back to them. If you get bored of plain water but still want something light and easy to use, these are definitely worth trying.

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.

Good for long bike rides. Can refill water bottles at any tap and just drop a tab in. Flavour is ok. I dont find plain water very appealing and generally forget to drink enough but adding flavour helps me drink more. Slight fizz can be annoying but dies away if bottle is not fully sealed. Relatively good value against other products but I still dont see why these things cost this much for a bit of salt and flavouring. Tend to use only for special occasions like enduro events and holidays. Carrying a partially full tube on the bike will cause the remaining tabs to rattle and grind away producing a lot of dust. However tabs removed and carried loose quickly deteriorate as they absorb ambient moisture from the air (effect of the salt). Solution is to take just enough to last planned trip and wrap tightly in small bag or foil.

Taste - gross. I don't like berry flavoured anything but they were on offer lol. Works? Very well. I felt more awake on my flight, think they helped me not have a migraine ( I get so many of them, I knew a flight in hot weather to the States would set my head off, but these definitely helped!) I was also worried about DVT on the flight being overweight, plus I stupidly left my flight socks at home, but these did help me feel more alert, and I made sure I walked lots! But I would buy them again as they did help me. After an 11 hour flight and no sleep I felt awake, alert, and still quite fresh thanks to these.

Purchased for a reasonable price. Tastes OK too.

Too sweet due to sucralose. It doesn't say how much sucralose is in them which is concerning 😟 not sure they do much for me. Wish they used Stevia instead.

Great for a pickmeup! I have just started to use these and wish I had tried them sooner. Taste is okay, quite pleasant and not salty like other hydration tablets I have tasted. I like the fact that they don't contain sugar as it helps me to keep on track with my diet. They dissolve quickly in the water and are not thick in texture as some others are. I feel the benefits almost instantly Great price and will continue to use.

An amazing product as it literally stopped my overnight cramps immediately .. I know when I've forgotten or run out so have it on subscription now

Dan una energía extra para salidas de larga duración

I regularly buy these in bulk as my friends help themselves to a tube whenever they are over. I particularly like the grapefruit with caffeine and the berry tubes makes a great change. They have a great favour, no aftertaste and provide good electrolytes during exercise or just encouraging me to stay hydrated. The caffeine boost is great !

Absolut Ideal nach dem Ausdauertraining. Schmeckt natürlich.

👍

Always take these on my rides gives you that little bit of energy boost for later stages and replenishes salts. I like the taste, simple to carry and good price
