Editorial review

Each pack contains 20 effervescent tablets in berry flavour, designed to dissolve quickly in water without added sugar. The formula includes potassium, magnesium, and calcium—minerals your muscles and nervous system rely on during physical activity. These aren't energy drinks; they're pure hydration support.
The electrolyte complex is balanced with a specific sodium concentration to encourage proper fluid absorption, helping your body maintain water balance when you're pushing hard in training or competition. Whether you're cycling, running, gym work, or any moderate to intense activity, these tablets keep you topped up without the crash of sugary sports drinks.
Science in Sport has been working with research institutes, elite athletes, and sports scientists since 1992, so the formula isn't guesswork. The tablets are vegan-friendly, contain no GMOs, and come in six flavours if berry isn't your pick. Simply drop one tablet into your water bottle, wait for it to dissolve, and drink.
At around £7.50 for 20 tablets, you're looking at roughly 37p per serving—competitive for an electrolyte product if you're training regularly. The tablets are lightweight and travel well, making them ideal for gym bags, backpacks, or race kits. With 4.6 stars across thousands of reviews, they've proven reliable for athletes who just want hydration without fuss.
Price trend
The list price sits at £7.50, which is roughly mid-range for electrolyte tablets from established sports nutrition brands.

Worth monitoring if your local Amazon stock drops below this point—that's when the deal genuinely shines for bulk buyers.
