HIGH5 ZERO Caffeine Hit — Zero‑sugar hydration with a mental edge

Hit your training and your to‑do list with the same intensity. HIGH5 ZERO Caffeine Hit are fast-dissolving electrolyte tablets that turn your water bottle into a crisp, berry-flavoured hydration drink — without the sugar or calories. Each tab delivers 75 mg of caffeine to help you feel more focused, plus essential electrolytes to support fluid balance when you’re working hard.

Train hard, think fast

Whether you’re clipping in for a turbo session, pushing pace on your lunchtime run, or grinding through a late-night deadline, ZERO Caffeine Hit helps you stay on it. Caffeine supports alertness and reaction time, while a balanced blend of sodium, potassium and magnesium replaces what sweat takes out — so your water works harder.

Light, clean and easy to carry

No sticky bottles, no sugar crash, no artificial colours or preservatives. Just refreshing berry flavour that mixes clear and goes down smooth. The tabs snap in half so you can dial in your preferred strength, from a gentle lift to a full caffeine hit.

Built for performance — and real life

  • Zero calories for everyday hydration and weight-conscious training blocks.
  • Vitamin C supports normal immune function and helps protect cells from oxidative stress.
  • Perfect before and during exercise, on commutes, road trips, shifts, lectures and study sessions.
  • Drop one tablet into 500 ml of water and you’re out the door.

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.

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.

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.

Flavour not great, but definitely work well to keep you alert and refreshed.

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.

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.

Very berry

Slightly sweet for my taste but a nice overall flavour. The caffeine boost is very welcomed as it gives you a tangible boost. Great for electrolytes, pre or post workout too!

Energy booster

I have used flavored amino energy drinks, but they often tasted a bit syrupy to me. I like this stuff. Even when I put it in a smaller quantity of water, it tastes good. Most important it gives me that extra boost I need at the gym. I like the pink grapefruit flavor better than the other flavors.

Regular buyer

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 !
