Are SiS products suitable for vegetarians and vegans? Which products are Gluten free?
- Most of our products are suitable for vegetarians. The only products that may not be suitable for vegetarians are the SiS Protein Bars in both Chocolate & Peanut and Mint Chocolate flavours. Only SiS GO Electrolyte powder, SiS GO Energy powder, SiS GO Hydro and SiS GO gels (including isotonic energy and all specialty gels) are suitable for vegans. Please see our table below for further allergen information:
When should I use SiS GO Electrolyte rather than SiS GO Energy or SiS GO Hydro?
- Fluid is best absorbed when delivered as part of a carbohydrate-electrolyte drink, so SiS GO Electrolyte is the primary option for hydration and energy in events longer than 90 minutes.
- SiS GO Energy can be used in cooler conditions when your sweat rate is lower, or before endurance activity as part of a carbohydrate loading regime. SiS GO Hydro does not contain any energy, so it could be used in conjunction with SiS GO Energy or for sessions lasting less than one hour when no additional carbohydrate is required.
When should I use SiS REGO Rapid Recovery versus SiS Whey Protein?
- The main difference between the two products is the carbohydrate content. SiS REGO Rapid Recovery has 25g of carbohydrate and 20g of protein per serving. It is best to use it for after training sessions which have significantly depleted your glycogen stores, such as long endurance or high intensity sessions.
- SiS Whey Protein contains 23g protein per serving, with less than 2g each of carbohydrate or fat per serving. This makes it a convenient source of high quality protein with very little else, ideal for supporting your lean muscle mass.
Are SiS products suitable for Diabetics?
- All SiS products can be used by diabetics if they take account of the carbohydrate content and build it into a nutritional strategy. Please speak to your GP if you are unsure.
Are SiS GO Isotonic Energy gels designed to replace isotonic drinks?
- No, they were designed to make it easy for an athlete to take an energy boost that is convenient during exercise and light on the stomach. More concentrated gels, particularly those which contain simple sugars such as glucose and fructose are more likely to cause gastric distress. No additional water is needed to help the absorption of SiS GO Isotonic gels, but you should still drink to remain hydrated during your activity.
Can I mix SiS REGO Rapid Recovery or Whey Protein with milk rather than water?
- It is not recommended to do so. Mixing it with milk will completely change the behaviour of the product. The products have been designed to provide a source of rapidly digested protein to aid recovery as quickly as possible. Milk is 80% casein, which is a slowly digested protein. That is why we use it in our Overnight Protein Recovery Product to provide a source of slowly digested protein as you sleep.
What are the use by dates on your products?
- The use by dates on our products are a minimum of 6 months from the date of purchase on all products with the exception of WHEY20, which is a minimum of 3 months from the date of purchase.
Are all of your products informed sport tested?
- All of our products are Informed Sport tested. Most of our products are tested under the unique Triple Testing method that provides unrivalled confidence for our athletes. For further information, please see our Informed Sport information page.
Do you use any sweeteners in your products?
- We use some sweeteners in various products across our range. Those used are Aspartame, Acesulfame K and Sucralose either singularly or in combination with each other. All of these sweeteners have been heavily tested, as with all aspects of our products, and are completely safe for consumption. For further information, full nutritional breakdowns and ingredients can be found on each product page.
