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

I bought this to help with cramps I was experiencing as a side effect of medication, possibly linked to increased water intake. I’d read that keeping electrolytes topped up might help, and wanted something reasonably priced to try without committing to a huge tub. The taste is pleasant - light blackcurrant flavour that reminds me a bit of squash. It’s not overly sweet, which I personally prefer. Dissolves well in water with no noticeable residue left at the bottom of the cup. I usually add one tablet to around 700ml of water, give it a quick stir, and it’s good to go after a minute or so. In terms of effectiveness, I can’t say I feel dramatically more hydrated, but I do find it easier to drink than plain water, and the cramps I was experiencing have eased, which is what I was hoping for. I’ve been using one a day at home, but the tube packaging makes it easy to take on the go if needed. The lid can be a bit fiddly to open sometimes, although that may partly be down to me having long nails rather than an issue with the tube itself! Overall, I think these are good value and a handy option if you struggle to drink plain water or want a simple way to add electrolytes without anything too overly sweet.

What to say, exactly as described and I was pleased the blackcurrant flavour is quite nice. Taste a bit like blackcurrant flavour squash, but significantly less sweet. A bit as if you put the tiniest drop of it in the water. This is excellent if you have diabetes and you’ve been running high blood sugars and cannot stop drinking. It breaks that cycle and it relieves that thirst. I also drink these when I need more liquids but want something nicier than water. It mixes well and it does not leave a patina on top of the water as some do. It has a little of fizz but it doesn’t feel sparkly, and based on research this has a good amount and balance of electrolytes, so I can’t wait for it to be on offer again! Also it’s generally decent value as one tablet will do 750ml or up to a L so great! - you can put 1 tab in 400-500ml too if you want a more concentrated flavour too. Would recommend

Taste nice. Slow to disolve

OMG I LOVE THESE. 😍 I have now tried, Berry, Blackcurrant & tropical & they’re all delicious. I add to water but they are absolutely delicious & so refreshing in a glass of LEMONADE. When I need a quick boost or I want something refreshing I have them in lemonade. I love these, they definitely give you a boost, my body thanks me when I have them & if I miss one I know cos I get bad craving that’s usually when the lemonade comes out haha. I would recommend these to everyone. They are also amazing at relieving headaches, I had a bad one a few days ago so downed a glass of lemonade with one of these & it went instantly.

Really pleased with the High5 Electrolytes Tablets (Berry). They mix super easily in water with no chalky bits, and the flavour is nice and subtle—not too sweet or overpowering, just refreshing. Perfect for workouts or hot days when you need a quick electrolyte boost. My water actually tastes nice now, which makes staying hydrated a lot easier!

Great product and dissolves easily. Good taste. Take them on hikes

The flavor is gustatorily overwhelming. They take a while to dissolve and leave powdery stuff in the water. They make the pressure in my head feel lifted, so not sure if that means they are hydrating.

This 20-tablet tube of HIGH5 ZERO offers a convenient, effervescent solution for replenishing electrolytes without added calories or sugar. The tablets dissolve relatively quickly and provide a balanced mix of sodium, magnesium, and potassium alongside Vitamin C. Pros: Zero Sugar/Calories: Ideal for those tracking macros or managing blood sugar while training. Dissolvability: Tablets break down fully in 750ml of water with minimal residue or sediment. Portability: The lightweight tube is durable and fits easily into gym bags or cycling jerseys. Scored Design: Tablets are pre-scored in the middle, making it easy to snap them in half for smaller bottles or weaker concentrations. Cons: Subtle Flavour: The blackcurrant taste is quite mild; those preferring a bold, juice-like intensity may find it slightly diluted at the recommended 750ml ratio. Sweetener Aftertaste: Because it relies on sorbitol and sucralose, there is a noticeable artificial sweetener lingering on the palate. Scent vs. Taste: The initial aroma upon opening the tube is stronger than the actual flavour produced once dissolved.
