SiS Hydro Tablets Strawberry and Lime
Strawberry and lime, a combination that tastes fresher than you might expect from a sports tablet. SiS Hydro Tablets Strawberry and Lime contain the same mineral formula as the other flavours in the range: 345 mg sodium, 65 mg potassium, 102 mg calcium and 8 mg magnesium per tablet. The red colour in the glass comes from beetroot, a beet-based colouring. This flavour also contains green tea extract and is free from sugar, lactose and gluten. Suitable for vegans.
What you lose through sweat
Of all the minerals you lose through sweat, sodium is lost in the largest quantities: depending on your body and the conditions, 200 to 2000 milligrams per litre of sweat. How much you sweat depends on intensity, temperature, humidity and how well you are accustomed to heat. Each tablet provides 345 mg sodium, 65 mg potassium, 102 mg calcium and 8 mg magnesium, and dissolves to a sodium concentration of 30 mmol/L in 500 ml of water. That concentration was not chosen at random.
30 mmol/L and the British sailors in Beijing
In 2008, the British Olympic sailing team asked SiS for help with their hydration strategy. Sailors sweat a lot, even though that may seem contradictory, and in changing weather and wind conditions, fluid loss is difficult to estimate. SiS formulated a tablet that provides exactly 30 mmol/L of sodium in 500 ml of water. Since then, the formula has remained virtually unchanged. Four minerals in each tablet: sodium, potassium, calcium and magnesium. Not one, not two.
Three B vitamins, a modest but concrete addition
Vitamins B1, B2 and B6 are not leading roles in this product, but they are included. Thiamine (B1) and riboflavin (B2) contribute to normal energy-yielding metabolism, and vitamin B6 contributes to normal protein and glycogen metabolism. The amounts are modest: 0.2 mg B1, 0.3 mg B2 and 0.4 mg B6 per tablet, providing 18%, 21% and 29% of the daily reference intake, respectively. Enough to make the claim, and no more than that.
Who is this product actually for?
For athletes who want to drink during shorter training sessions without consuming carbohydrates or sugars, and for those who drink more than usual on hot days and are looking for a drink with minerals. The tablet dissolves in 500 ml of water, contains virtually no calories and is suitable for vegans. Each batch is tested by Informed Sport for substances on the WADA banned list, so competitive athletes can also use it without hesitation.
The strawberry-lime flavour is popular with those who find the standard lemon flavour too neutral. The fresh lime note gives the glass a slightly tangier character without feeling sweet. Easy to drink cold or at room temperature.
