HIGH5 ZERO Electrolyte Tablet - Hydration Tablets Enhanced with Vitamin C - 0 Calories & Sugar Free - Boost Hydration, Performance & Wellness - Berry, 160 Tablets (20x, Pack of 8)

The main reason I purchased these as I have been using subscription hydration drinks for a few months but it has gotten too costly. I found these for a great price for 20 servings and decided to give them a go. I went with the berry flavour which was great, the taste is very smooth and a bit salty (expected with hydration drinks). They are very easy to use compared to using powder and good for portable use as I can easily make them at work and on the go. The hydration qualities are great and I feel very refreshed and hydrated after using!

I love these hydration tablets - they've been my saviour since starting intermittent fasting (16/8) 6 weeks ago. My first week of fasting made me feel lethargic with headaches every night during my fast. I also felt hungry and couldn't sleep. I almost gave up fasting until I read about electrolytes, so I purchased these. I've been taking two to three tablets daily, depending on how I feel. I have a Tropical or Berry flavoured tablet dissolved in water to use during 20 to 30-mile Zwift rides/races. During the night (when fasting and feeling hungry), I break up a Berry flavoured tablet to suck on - it tastes great and is similar to Barrat Refreshers. I found that Tropical is the best flavour to use in water followed closely by Strawberry & Kiwi. These two flavours taste too artificial to suck on. Berry is fine in water but improves with a dash of no added sugar berry flavoured squash. These tablets have boosted my performance on the bike (I no longer drink sugary Lucozade) and have irradicated headaches, lethargy and hunger pangs before bed. I'm starting my 7th week of fasting and 15lbs down with another 15-20lbs to go. I've struggled with weight for the past 20 years and tried every diet going. Fasting is the only diet (or I should call it a lifestyle) that works, and these tablets are a must for this new way of life. Update (6th June 2021): I've now lost 25lbs (11.3kg) since 14th March, and that includes a recent weeks holiday filled with plenty of beer and food (with desserts). I can't quite believe how fasting has transformed my body, and these tabs have been a key part of this process. ​I've gone from XL t-shirts to Medium and have never been happier! I plan to have a six-pack by August. :) Update (24th September 2021): I've lost 35lbs (2.5 stone), reaching my goal weight back in mid-August. I'm now working on body recomposition to get more definition with weight training, less cardio, more protein (supplementing with Myprotein Impact Whey Protein shakes), and lowering carbs (but not cutting them out). I just had a big bowl of lasagne with garlic bread :). I'm still fasting roughly 16 hours (between 8 pm and 12 pm) as it's a way of life for me, and I still use these tabs daily for exercise and fasting. I eat two meals a day with the occasional sweet treat and a few beers down the pub. I have never tracked food intake from day one but have a good understanding of nutrition and macronutrients. I used to eat a big bowl of porridge for breakfast, but now I have a big 4-egg omelette stuffed with ham, mushroom, and cheese with half a tin of baked beans. I'm no longer weighing myself daily since reaching my goal weight but keep myself in check with the trusty tape measure.

I bought these to support whilst completing a 5 day water fast. The flavour was subtle and obviously slightly salty tasting. They helped compared to just water only and give much needed salts during a fast. I only dropped 1 star as the flavour could have been stronger but overall, well packaged and great for the job at hand.

These HIGH5 ZERO electrolyte tablets have been a really useful addition to my hydration routine, especially during workouts and warmer days. They’re very easy to use just drop one tablet into water and it dissolves quickly without any hassle or residue. The taste is light and refreshing rather than overly sweet, which I actually prefer when I’m exercising. It feels more like a clean hydration drink than a sugary sports beverage. The berry/citrus-style flavours are pleasant and not artificial tasting. What I really like is that they’re zero sugar and low calorie, yet still include key electrolytes like sodium, potassium, and magnesium, along with added Vitamin C. They’ve been helpful for staying hydrated during training and helping reduce that “drained” feeling after longer sessions. They’re also very convenient to carry around the tube packaging fits easily in a gym bag or backpack, making them ideal for travel, running, or general daily hydration. Overall, a simple but effective hydration product that does exactly what it claims. I’d happily keep using them as part of my training and daily routine.

HIGH5 ZERO Electrolyte Tablets are a really solid choice if you want effective hydration without sugar, calories, or artificial heaviness. They dissolve easily in water and provide noticeably better hydration than water alone - especially during workouts, hot weather, fasting, or long travel days. The electrolyte balance feels well judged: enough sodium to actually support hydration, alongside potassium, magnesium, and calcium for muscle function and recovery. The zero-calorie, sugar-free formulation is a big plus. You don’t get the sticky sweetness or energy-drink crash, just a light, refreshing flavour. The berry flavour is pleasant and subtle rather than overpowering, making it easy to drink throughout the day. I’ve found these particularly useful for training sessions, long walks, and days where hydration tends to slip. They’re also handy for travel and on-the-go use - just drop one tablet into a bottle and you’re sorted. Including vitamin C and a small amount of green tea adds a nice wellness touch without feeling gimmicky. With 160 tablets in the pack, it’s also good value and lasts a long time. Best for: • Exercise, endurance training, and recovery • Hot weather, travel, fasting, or low-carb/keto diets • Anyone wanting hydration support without sugar Effective, great-tasting, zero-sugar electrolyte tablets that do exactly what they promise. A staple for everyday hydration and performance.

After trying loads of electrolyte tablets, I keep coming back to HIGH5 ZERO – Berry. It’s light, effective, sugar-free, and seriously refreshing — especially when you need hydration that actually works during a workout or hot day. But here’s the real hack: drop it into cold sparkling water and you’ve got one of the best fizzy hydration drinks you’ll ever taste. No joke — it’s like functional soda. 🥤✨ ⸻ ✅ What I Loved: 🍓 Tasty and sugar-free – The berry flavour is mild, clean, and doesn’t linger weirdly. Great if you’re cutting sugar or on a low-carb diet — I drink it even while fasting. 💧 Hydration that delivers – This has helped me avoid post-run cramps more than once, especially during summer. I notice the difference when I don’t use it. ⚡ Vitamin C included – Feels like a small immunity boost without needing to think about it. 🥤 Pro tip: add to cold sparkling water! – Game-changer. Makes hydration feel like a treat. I now look forward to it post-workout or even as a midday pick-me-up. ⸻ ⚠️ What Could Be Better: ⏳ Fizz disappears quickly – If you’re using still water, drink it soon after it dissolves or you’ll miss the bubbly effect. 🎯 Flavour is subtle – I love the lightness, but if you’re into bold flavours, it might come off a bit too mild. ⸻ 🙌 Perfect For: ✅ Runners, cyclists, and gym lovers ✅ People doing intermittent fasting or keto ✅ Anyone tired of sugary hydration drinks ✅ Those who want a healthy soda alternative 🍹 ⸻ Whether you’re working out or just trying to drink more water, this stuff is a winner. The berry flavour + sparkling water combo is a next-level hydration hack I didn’t know I needed. 💦🏃‍♂️🌟

Good value and the product left no aftertaste

Most electrolytes are quite expensive. These are regularly on offer and just as good as the expensive ones. They dissolve really quickly, no stomach issues.

Tolles und wirksames Produkt.

Easy to drink flavour

El producto en si parece funcionar y tiene buena pinta (probado en una sola salida), pero la fecha de caducidad no llega a dos meses lo que me parece un periodo excesivamente corto que además podrían haber indicado. Conclusión: buen producto, vendedor un pelín cara dura.

Good

This product was as described, arrived on time in great condition. I wish the company had a multi pack instead of just ordering one at a time, especially for the cost. I use them for when I hike, mountain bike or snowshoe. They're handy to have in the car too.
