HIGH5 ZERO Electrolyte Tablets - Hydration Tablets Enhanced with Vitamin C - 0 Calories & Sugar Free - Boost Hydration, Performance & Wellness - Orange & Cherry (20x, Pack of 1)

Long distance runners are at higher risk of hyponatraemia (electrolyte imbalance) than of de-hydration and this can cause nausea, vomiting and even be fatal. There are apparently no reported cases of people dying from de-hydration in any world marathon or Ironman event, but a significant number have died of hyponatraemia. The cause is normally that people drink too much water and so dilute their concentration of electrolytes. When exercising it is important not to drink too much water and to try and maintain the body's electrolyte balance. High5 Zero come in tubes of twenty tablets and each tablet will when mixed with water make 0.5 to 0.75 litres of electrolyte solution. The tablets are quite hard and maintain their shape and consistency even when the tube is dropped. They are scored down the centre to make them easy to snap in half, this make it possible to drop them into a bottle with only a think neck. One of the best features of these tablets is their taste. They are really refreshing and not sweet or sticky like some others. The orange and the berry flavours are my favourite of the four flavours. They taste good at room temperature and even in the sauna (but doesn't any drink taste good in a sauna?) The tube is robust and easy to carry. This makes them easy to take on holiday or to go hiking with. I did used to suffer periodically with cramp when I was running which is what prompted me to try them. I don't suffer with cramp anymore and I don't think that this is simply a coincidence. The tablets may seem a little expensive but in fact when you consider that a single tube will make 10-15 litres of delicious tasting electrolyte solution the cost seems far more reasonable. My only reservation is than an average person will sweat at the rate of around 1 litre per hour during extended exercise at average temperature and that sweat will contain something like 900mg of sodium. Each High5 tablet contains 260mg of sodium, 75mg of Potassium, 60mg of Magnesium and 9mg of Calcium, and so a single tablet in 0.5l of water could still result in sodium levels becoming depleted during longer races. For such long races you would probably need two tablets per 0.5l to mitigate this more fully. I will still give these tablets a considered five stars for their taste, efficacy and ease of use. It's no drama to put an extra tablet in the bottle for longer periods of running.

Great tasting product that really hits the spot when training hard.

In general, these are my go to electrolytes. Have tried a few flavours: lime, berry, tropical and strawberry kiwi are all reasonably nice tasting. Orange cherry is awful - not sure what it tastes like, but it is not either fruit. Just to help if you're choosing flavours.

I've been using HIGH5 ZERO Electrolyte Tablets for a while now, and they’ve become my go-to for staying hydrated during workouts and hot weather. Just drop one in your water bottle, and you get a lightly flavored, sugar-free drink that helps replenish electrolytes without adding calories. The flavors are clean and refreshing—Berry is my favorite, but Citrus and Pink Grapefruit are also solid options. They’re not overly sweet, and there’s no odd aftertaste like you sometimes get with sugar-free drinks. I've noticed a real difference in my energy and recovery, especially on longer runs or intense gym days. The tablets are also really portable, so I keep a tube in my bag for when I’m on the go. Overall, HIGH5 ZERO makes it easy to stay hydrated and feel good without relying on sugary sports drinks.

Really nice - good price too

The Strawberry flavour is passible, but it is incredibly weak and has bits floating around after it has totally dissolved. I've had one disc and wont be having anymore. The orange & cherry flavour is vile, I couldn't finish it.

Exactly what I needed, cheaper than at the shops. Easy to dissolve and a nice flavour when you have a cold! Not too sure if it actually helped my cold but a nice placebo effect regardless :)

These HIGH5 ZERO Electrolyte Tablets have become one of those things I didn’t realise I’d use as much as I do. They dissolve quickly, taste genuinely good (which is not always a given with electrolyte tablets), and don’t have that overly salty or artificial flavour some alternatives suffer from. Light, refreshing, and easy to drink. What really makes them stand out is the convenience. Keep a tube in your bag, grab a bottle of water when you’re out and about, drop one in, and you’ve instantly got a proper hydration boost. No planning, no bulky drinks, no faff. They’re especially useful when you’re feeling a bit run down, dehydrated, or when a headache or migraine is creeping in. Staying properly hydrated makes a noticeable difference, and these make it effortless to actually do something about it. The fact they’re zero calories is a big plus too — all the benefits without loading up on sugar like some sports drinks. If you want something simple, effective, and easy to use for hydration — whether it’s daily use, workouts, or just getting through a rough day — these are a great option. Five stars. Convenient, great tasting, and far more useful than you’d expect from a fizzy tablet.

If you sweat hard in a hot climate (like I do), these are a great thing. What you need, without anything you don't need. Recommended.

Excellent product and prompt delivery. Cheers!
