Energy supplements are carbohydrate-based products designed to fuel your training — before, during, or after your session. Whether you're heading into an intense workout, pushing through a long endurance session, or topping up your carb intake around training, the range here covers every format and fast-digesting carb source you need.
From instant oats and cream of rice to cyclic dextrin and maltodextrin, each product is built around carbohydrates — the body's preferred fuel source. Carbohydrates contribute to the recovery of normal muscle function after highly intensive and/or long-lasting physical exercise leading to muscle fatigue and the depletion of glycogen stores in skeletal muscle.1 You'll find straightforward, no-fuss options across the full range, all developed by Myprotein's expert nutritionists.
Who Energy Supplements Are For
These products are a natural fit for anyone who trains with intensity and needs a reliable, convenient carbohydrate source to work around. That includes gym-goers looking for a clean pre-workout fuel, endurance athletes who need sustained carb availability, and anyone whose daily intake falls short of their training demands.
They're also well-suited to those who want flexible, easy-to-prepare options. Not everyone has time to build every meal from scratch — having a fast-mixing carb powder or a high-carb breakfast option like cream of rice or oats in the rotation makes hitting daily targets a lot more manageable.
When to Use Energy Supplements
Timing comes down to what you're using and why. Fast-digesting sources like maltodextrin and cyclic dextrin are well-suited to the period immediately before or after training, when quick carbohydrate availability is the priority. Slower-releasing whole food options — oats and cream of rice — are better placed at breakfast or as a pre-workout meal an hour or two before you train.
For longer sessions, some athletes incorporate carbohydrate sources during training as well. Carbohydrate solutions contribute to the improvement of physical performance during high-intensity and long-lasting physical exercise in trained adults.2 Knowing the digestion rate of each product helps you time things right and get more from every session.
Energy Supplements Benefits
A Format for Every Preference
The range spans instant powders, rolled oats, cream of rice, and protein-enriched oat blends — so there's a format that fits your prep style, whether that's a quick shake or a proper breakfast bowl. Serving sizes are clear and the nutrition is straightforward, making them easy to fit into any meal plan.
High Carbohydrate Content Per Serving
These products are built around meaningful carbohydrate amounts. Options like 100% Instant Oats deliver 62g of carbs per serving, while 100% Maltodextrin Carbs provides 50g per serving — making it easy to hit significant carb targets without relying on large volumes of whole food alone.
Brain Function on Training Days
Carbohydrates contribute to the maintenance of normal brain function.3 On heavy training days, keeping carb intake consistent helps maintain the mental side of performance just as much as the physical — something easy to overlook when you're focused solely on the physical output.
Versatile Across Diets and Goals
Whether you're in a building phase, maintaining, or working around a calorie deficit on non-training days, carbohydrate supplements allow precise control over intake. Adjust serving sizes up or down depending on the day's demands — it's that straightforward.

FAQs
What are energy supplements for working out?
Energy supplements for working out are carbohydrate-based products that provide fuel before, during, or after physical activity. They typically come as fast-digesting powders like maltodextrin or cyclic dextrin, or whole-food-based options like oats and cream of rice. Each format digests at a different rate, making them suited to different points around training. Carbohydrates are the body's primary energy substrate during exercise, and these supplements make it straightforward to hit your daily carb targets around your sessions.
What's the difference between sports energy supplements and regular food carbs?
Sports energy supplements are formulated for convenience, speed of preparation, and consistent macronutrient content per serving. Products like 100% Maltodextrin Carbs or 100% Cyclic-Dextrin Carbs are highly processed carbohydrate sources that mix quickly and digest rapidly — which can be harder to replicate through whole foods alone. Whole-food-based options in the range, like 100% Rolled Oats or 100% Instant Oats, bridge the gap between convenience and more traditional nutrition sources, offering fibre alongside the carbohydrate content.
Which carbohydrate supplement should I choose?
The right choice depends on when and how you're using it. For a quick-mixing, fast-acting carb source, 100% Maltodextrin Carbs delivers 50g of carbs per serving and is easy to add to a shake. If you want something more substantial as a pre-training meal or breakfast, 100% Instant Oats offers 62g of carbs per serving alongside 11g of protein, making it a more complete option. Slower-releasing formats like rolled oats or cream of rice work well earlier in the day when there's more time before you train.
What are carb supplements and how are they used?
Carb supplements are products concentrated in carbohydrates — the macronutrient your body uses as its primary fuel during physical exercise. They're used by athletes and regular gym-goers to make up carbohydrate targets that are difficult to hit through meals alone, or to time carb intake precisely around training. Formats vary from fine powders that dissolve into liquids to oat-based products prepared like porridge. Most are unflavoured or available in a small number of flavours to keep things flexible.
When should I take energy supplements for the gym?
Timing depends on the product. Fast-digesting carb powders like maltodextrin and cyclic dextrin are best consumed shortly before or after training when rapid carbohydrate availability matters most. Oat-based products — including 100% Instant Oats and Origin Cream of Rice — are better suited to a meal 60–120 minutes before training due to their slower digestion profile. For longer sessions, consuming a carbohydrate source during activity is also a common approach among endurance-focused athletes.
Are gym energy supplements suitable for endurance training?
Carbohydrate-based energy supplements are commonly used in endurance sport, where sustained fuel availability across extended sessions is a priority. Carbohydrate solutions contribute to the improvement of physical performance during high-intensity and long-lasting physical exercise in trained adults.2 Fast-digesting carb sources are particularly practical in this context, as they can be consumed during activity without causing the digestive discomfort that heavier whole-food options sometimes produce.
How many carbs should I be taking around training?
Individual carbohydrate needs vary based on training volume, body weight, and goals — there's no single number that applies universally. As a general reference point, carbohydrates contribute to the maintenance of normal brain function,3 and overall daily intake from all sources is what matters most. Products in this range clearly display carbohydrate content per serving, making it straightforward to track and adjust your intake based on your specific targets.
Who developed the energy supplements in this range?
The energy supplements in this range were developed by Myprotein's expert nutritionists. Each product is formulated with clear, accurate nutritional information and straightforward ingredient lists — no unnecessary additives, just well-constructed carbohydrate sources built around what athletes and regular gym-goers actually need.
Do these energy supplements contain protein as well as carbs?
Some products in the range combine carbohydrates with protein. Protein Oats and Impact Whey Protein Milkshake both provide meaningful protein content alongside carbohydrates, which can be useful if you're looking to cover multiple macros in one serving. Others, like 100% Maltodextrin Carbs and 100% Cyclic-Dextrin Carbs, are pure carbohydrate sources with minimal protein — better suited to those who want to keep their macros separate and build meals with more precision.
What formats are available in the energy supplements range?
The range covers a wide variety of formats. Instant powders like maltodextrin and cyclic dextrin mix directly into water or shakes. Oat-based products — including 100% Instant Oats, 100% Rolled Oats, and Protein Oats — are prepared like porridge and work well as a substantial meal. Cream of rice is another whole-food-style option with a smooth texture. For something ready to drink, the Breakfast Smoothie offers a convenient liquid format. That breadth means there's a practical option regardless of your prep preferences or schedule.
