Manufacturer Contact Information SiS (Science in Sport) Limited, Unit 8A, Frontier Park, Blackburn BB1 3AL UK Science in Sport S.R.L. via Michelangelo Buonarroti, 39 – 20145 Milan, ITALIA Review: A lovely hydration tablet that does the job. - I’ve been cycling for MANY years indoors and IRL and for many years, as soon as I discovered the SIS Hydro, I vane been using these tablets. My favourite juice is pink grapefruit so I bought my first batch of these years ago and have been using them ever since. They do NOT produce an energy drink but supply the essential salts and minerals to replace the ones lost through sweat keeping you hydrated. They dissolve very easily and once the drink bottle has been shaken you have a pleasant tasting, not too sweet and sickly, drink that does the job it’s meant to. Review: Hydro Electro Power - Excellent craftsmanship goes into this product perception as expected. Easily water soluble tablets have their effect via this viable source. Zero sugar and added B vitamins can ensure you are making healthy choice for this kind of solution. Really enjoyable taste that adds precision results to routines. Impressive work from SIS. Thanks very very much. ## Features - Push Boundaries in Every Session: Single-serve effervescent tablets deliver a controlled combination of electrolytes and B vitamins, making hydration precise and accessible wherever your sport takes you - Build on Proven Science: Developed with elite athlete insight and rigorous research, these tablets offer targeted levels of sodium, potassium, calcium and magnesium to support normal muscle function and electrolyte balance - Prepare for Peak Performance: Features vitamin B1 and B2 to contribute to normal energy-yielding metabolism and carbohydrate conversion, and B6 to support protein metabolism during effort - Trust in Uncompromising Standards: Each batch is tested for banned substances, ensuring confidence and reliability for athletes determined to advance at every level - You can’t Beat the Science: Every SiS product is driven by research, developed with elite athletes, and tested with precision to deliver reliable, evidence-based performance nutrition for athletes at every level ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07WLQH485 | | Age Range Description | Adult | | Benefits | Hydrated,Improved Hydration,Hydration | | Best Sellers Rank | 11 in Health & Personal Care ( See Top 100 in Health & Personal Care ) 2 in Electrolyte Replacement Supplements 3 in Diet Shakes | | Brand | Science in Sport | | Brand Name | Science in Sport | | Colour | Pink | | Container Type | Bottle,Tube | | Customer Reviews | 4.6 out of 5 stars 1,802 Reviews | | Diet Type | Vegan | | Dosage Form | Tablet | | Flavour | Pink Grapefruit | | Global Trade Identification Number | 25025324007428 | | Item Dimensions | 34 x 34 x 146 millimetres | | Item Form | Tablet | | Item Nype Name | HEALTH_PERSONAL_CARE | | Item Weight | 0.11 Kilograms | | Item form | Tablet | | Item weight | 0.11 Kilograms | | Manufacturer | Science in Sport | | Manufacturer Contact Information | SiS (Science in Sport) Limited, Unit 8A, Frontier Park, Blackburn BB1 3AL UK Science in Sport S.R.L. via Michelangelo Buonarroti, 39 – 20145 Milan, ITALIA | | Manufacturer Part Number | 130306 | | Material Features | Gluten Free | | Model Name | HYDRO | | Model Number | 130306 | | Number of Items | 1 | | Primary Supplement Type | Vitamin B12 | | Primary supplement type | Vitamin B12 | | Special Ingredients | vitamin B6 | | Total Servings Per Container | 20 | | Unit Count | 20.0 count | | Unit count | 20.0 count | ## Product Details - **Brand:** Science in Sport - **Diet type:** Vegan - **Flavour:** Pink Grapefruit - **Item dimensions L x W x H:** 34 x 34 x 146 millimetres - **Item form:** Tablet - **Item weight:** 0.11 Kilograms - **Primary supplement type:** Vitamin B12 - **Product benefits:** Hydrated,Improved Hydration,Hydration - **Special ingredients:** vitamin B6 - **Unit count:** 20.0 count ## Images ![Hydro Electrolyte Tablets, Pink Grapefruit, 20 Tablets | Four Key Electrolytes and B Vitamins, Sugar-Free, Vegan Sports Hydration - Image 1](https://m.media-amazon.com/images/I/71em57+R7YL.jpg) ## Available Options This product comes in different **Size, Flavor** options. ## Questions & Answers **Q: Why are there artificial sweeteners?** A: Not being the manufacturer, I don’t know. I would prefer it if they did not use them. Of more concern to me, though, is that as well as the sweetener sucralose, they are also using sorbitol, though as a humectant (preserving moisture) rather than a sweetener. Surely we are still consuming it though? **Q: What's the equivalent of one tablet dissolved into 500ml of water to just drinking water? Is it like drinking 1, 2, or 3 litres water?** A: There is no equivalent. SiS (or any other sports electrolyte formula) restore the electrolyte balance in your body. When you sweat you are losing more than just water, you are also losing 'salts' (big simplification!). Just drinking plain water during sport does not rehydrate you properly, which is why people add products such as this. In fact if you start to consume large volumes of water you will make the situation worse and could end up with a condition called Hyponatremia (low sodium concentration in the blood). Bottom line if you are doing exercise which causes you to sweat then re-hydrate properly using an electrolyte supplement added to water... With or without carbohydrate depending on your calorific needs. edstivala.com **Q: why this price is so sick? £7? really?! in Lidl I can pay around £4.5 per tube/20tabs.** A: I got mine for £5 online but it seems to vary for no good reason **Q: Can you take them in the evening?** A: Yes ## Customer Reviews ### ⭐⭐⭐⭐⭐ A lovely hydration tablet that does the job. *by P***S on 2 May 2026* I’ve been cycling for MANY years indoors and IRL and for many years, as soon as I discovered the SIS Hydro, I vane been using these tablets.
