Science in Sport FAQ & Buying Guide

What are SiS's most popular products at Fuel Supplements? The GO Isotonic Energy Gel singles and Beta Fuel gels lead the way, with flavours like Orange, Lemon Lime, Tropical, and Strawberry & Lime. Serious mileage buyers usually go straight to the 30-count boxes. What's the difference between GO Isotonic and Beta Fuel? GO Isotonic is the lighter everyday training gel — its isotonic formula means no water needed. Beta Fuel carries a bigger carbohydrate payload per gel and is built for long races and high-output sessions; it also comes as a chew if you prefer solid fuel. How many energy gels should I take during a workout? A common approach is one gel every 20–30 minutes during efforts longer than about an hour, adjusted to your gut tolerance — practise your fuelling in training, never on race day. Follow the guidance on each pack. Does Fuel Supplements ship Science in Sport across Canada? Yes. SiS gels and chews ship Canada-wide from our BC warehouses, free on orders over $100, with same-day pickup in Port Coquitlam.

Product Description

SIS GO Isotonic Gel Lemon Lime is a fast-absorbing energy gel from Science in Sport, built for endurance athletes who need on-the-go carbohydrate fuel during training or racing. This pack of 6 x 60mL gels is formulated as isotonic, meaning it's designed to be taken without needing extra water. Available at Fuel Supplements with fast shipping across Canada.

When to Use It

SIS GO Isotonic Gel suits runners, cyclists, and endurance athletes who need quick carbohydrate fuel mid-session or mid-race, especially over longer distances where consistent energy intake matters. Because it's isotonic, it works well when water access is limited or during high-intensity segments where stopping to drink isn't practical. Many athletes carry a few gels for long rides, marathons, or triathlons and pair them with regular hydration throughout the event.
