Energy supplements are carbohydrate-based formulas designed to fuel training, competition, and active lifestyles. Whether you're loading up before a session or topping up mid-workout, the right carbohydrate source makes a real difference to how you perform and how you feel when you're done. 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
The range here covers everything from slow-releasing oat-based carbs to fast-acting maltodextrin and cyclic dextrin — each with a different absorption rate, texture, and use case. All developed by Myprotein's expert nutritionists, they're built for people who take their training seriously and want precise control over their carbohydrate intake.
Who Energy Supplements Are For
These products are a natural fit for athletes, gym-goers, and endurance enthusiasts who are deliberate about what they consume around training. If you track your macros, follow a structured training plan, or find that your performance dips without adequate carbohydrate intake before or after a session, energy supplements give you a clean, consistent source to work with.
They're equally suited to those who struggle to hit their daily carbohydrate targets through food alone — whether that's due to a busy schedule, appetite, or the sheer volume of calories needed to fuel heavy training blocks. From runners and cyclists to weightlifters and team-sport athletes, carbohydrate-focused supplementation fits across a wide range of disciplines and goals.
When to Use Energy Supplements
Timing matters with carbohydrate supplementation. Fast-acting options like maltodextrin and cyclic dextrin are typically used immediately before, during, or right after training — periods when the body's demand for readily available carbohydrates is at its highest. Carbohydrate solutions contribute to the improvement of physical performance during high-intensity and long-lasting physical exercise in trained adults.2
Slower-releasing sources like rolled oats or instant oats are better placed earlier in the day — as part of a pre-workout meal or a morning routine that sets up sustained energy levels for training later. Mixing approaches across the day gives you both the steady baseline and the quick top-up when you need it most.
Energy Supplements Benefits
A Carbohydrate Source You Can Rely On
Each product delivers a precise, measurable amount of carbohydrates per serving — no guesswork, no hidden ingredients. Whether it's 50g from maltodextrin or 62g from instant oats, you know exactly what you're getting, which makes hitting daily carbohydrate targets straightforward.
Muscle Function After Hard Training
Carbohydrates contribute to the recovery of normal muscle function after highly intensive exercise that depletes glycogen stores in skeletal muscle.1 Getting that post-session carbohydrate intake right is a key part of any structured training approach.
Multiple Formats for Different Needs
From fine-milling powders that mix clean into shakes to rolled oats that work as a standalone meal, the format range here is practical. You can use different products at different points in the day depending on your digestion preference and training schedule.
Fits Alongside Protein for a Complete Stack
Carbohydrate supplements pair naturally with protein products. Protein contributes to the growth and maintenance of muscle mass3 — and combining that with well-timed carbohydrate intake gives you a more complete approach to fuelling and recovering from training.

FAQs
What are energy supplements?
Energy supplements are carbohydrate-based products formulated to provide a fast, reliable source of fuel around training. They typically come as powders — including oat-based options, maltodextrin, and cyclic dextrin — each with a different digestion rate suited to different points in a training day. They're used by athletes and active individuals who want precise control over their carbohydrate intake without relying solely on whole foods.
What's the difference between maltodextrin, cyclic dextrin, and oat-based carbs?
Maltodextrin is a fast-digesting carbohydrate derived from starch, making it a popular choice immediately around training. Cyclic dextrin is a more advanced form with a different molecular structure that some athletes prefer for its mixability and digestion speed. Oat-based options like rolled or instant oats are slower to digest and work well earlier in the day as part of a pre-workout meal, delivering a steady carbohydrate supply before a session.
Which energy supplement should I choose?
100% Instant Oats is a strong all-rounder — it delivers 62g of carbs per serving and 11g of protein, making it well-suited as a pre-training meal or a substantial morning option. If you want something faster-acting and more neutral for mixing into shakes, 100% Maltodextrin Carbs provides 50g of carbs per serving and absorbs quickly. For a whole-food oat option, 100% Rolled Oats packs in carbohydrates alongside natural fibre. Your choice depends on when and how you plan to use it.
When is the best time to take carbohydrate energy supplements?
Fast-acting carbohydrate supplements like maltodextrin are typically consumed immediately before, during, or after training — when the body needs carbohydrates quickly. Oat-based products are better placed 1–2 hours before a session as part of a meal, giving the body time to digest and draw on a more sustained carbohydrate source. Carbohydrate solutions contribute to the improvement of physical performance during high-intensity and long-lasting exercise in trained adults.2
Can I use energy supplements as part of a mass-gaining approach?
Many people use carbohydrate supplements specifically because they're a convenient way to increase daily calorie and carbohydrate intake without eating larger volumes of food. Paired with a protein source, they form a practical addition to a higher-calorie diet. Protein contributes to the growth and maintenance of muscle mass3 when combined with appropriate training and overall nutrition.
Are energy supplements suitable for endurance athletes?
Endurance athletes are one of the primary audiences for carbohydrate supplementation. During prolonged physical exercise, glycogen stores deplete — and carbohydrates contribute to the recovery of normal muscle function after highly intensive and long-lasting exercise that leads to muscle fatigue and glycogen depletion.1 Runners, cyclists, and team-sport athletes regularly use carbohydrate products before and after sessions to manage this.
How many carbs are in these products per serving?
Carbohydrate content varies by product. 100% Instant Oats delivers 62g of carbs per serving, 100% Maltodextrin Carbs provides 50g per serving, and 100% Rolled Oats is similarly packed with carbohydrates alongside natural fibre. Each product page includes full nutritional information so you can match the serving to your daily targets.
Who develops Myprotein's energy supplements?
Myprotein's energy supplements are developed by Myprotein's expert nutritionists. Every formula is designed with practical use in mind — focused on clean ingredients, accurate nutritional profiles, and formats that work for real training routines rather than theoretical ideals.
Do energy supplements contain protein as well?
Some do. 100% Instant Oats, for example, contains 11g of protein per serving alongside its 62g of carbohydrates — making it a dual-purpose option for those who want both macros in one product. Pure carbohydrate options like 100% Maltodextrin Carbs are formulated without added protein, giving you more flexibility to combine them with a separate protein source of your choice.
Are these products suitable for vegetarians and vegans?
Most carbohydrate-based energy supplements in this range are plant-derived — oats and maltodextrin are naturally vegan-friendly ingredients. Check the individual product label or product page for full allergen and dietary suitability information, as formulations can vary and manufacturing environments differ across products.
