Intra workout supplements are designed to be taken during your training session, giving your body the nutrients it needs right when you're working hardest. From fast-acting carbohydrates to essential amino acids and electrolytes, the range covers the key building blocks that serious athletes reach for mid-session.
Whether you're pushing through a long endurance session or grinding out high-intensity sets in the gym, intra workout nutrition is about keeping your body fuelled and your amino acid levels topped up throughout. The range includes everything from pure carb powders to comprehensive EAA formulas with electrolytes — all in formats built for easy mixing and fast absorption.
Who Intra Workout Supplements Are For
Intra workout supplements are a staple for anyone training at a level where session length and intensity matter. Endurance athletes, weightlifters, CrossFit enthusiasts, and team sport players all use intra workout nutrition to keep amino acids and carbohydrates available throughout their training.
They're equally relevant for anyone following a calorie-restricted diet who wants to ensure they're not falling short on essential amino acids during training. If your sessions regularly exceed 60 minutes, or you train fasted, having a dedicated intra workout drink in your routine is a practical way to cover your bases mid-session.
When to Use Intra Workout
As the name suggests, these supplements are taken during your workout — not before or after. The ideal window is from the first 15–20 minutes of your session through to the final sets. Sipping consistently throughout, rather than downing it all at once, is the standard approach most athletes use.
For carbohydrate-based intra workout drinks, longer sessions of 60 minutes or more are where they tend to make the most sense. EAA and electrolyte formulas are well-suited to any session length, particularly if you're training in a fasted state or in warm conditions where sweat loss is higher.
Intra Workout Benefits
Essential Amino Acids Mid-Session
EAAs are the nine amino acids the body can't produce on its own — meaning they have to come from food or supplements. Taking them during training keeps circulating amino acid levels topped up throughout your session. Protein contributes to the growth and maintenance of muscle mass1, and EAAs are the key components that make up dietary protein.
Fast-Acting Carbohydrates for Prolonged Training
Carbohydrate-based intra workout powders — like maltodextrin and cyclic dextrin — are rapidly digested sources of carbs that provide a steady supply of glucose during extended training. Carbohydrate-electrolyte solutions contribute to the maintenance of endurance performance during prolonged endurance exercise2.
Electrolyte Replenishment
Sweating means losing electrolytes — sodium, potassium, and magnesium chief among them. Some intra workout formulas include electrolytes alongside amino acids to address this directly during training. Carbohydrate-electrolyte solutions enhance the absorption of water during physical exercise3, making electrolyte-containing intra workout drinks particularly useful for longer or high-intensity sessions.
Versatile Formats to Suit Any Session
The range spans pure carb powders for endurance athletes, comprehensive EAA blends with electrolytes for gym-based training, and everything in between. Most come in powder form, designed to be mixed with water and sipped throughout your workout — simple, practical, and easy to customise to your own training needs.

FAQs
What is an intra workout supplement?
An intra workout supplement is a product formulated to be consumed during exercise, rather than before or after. They typically contain fast-digesting carbohydrates, essential amino acids (EAAs), electrolytes, or a combination of all three. The goal is to keep key nutrients available to the body throughout the training session, rather than relying solely on what was consumed beforehand.
What's the difference between EAAs and BCAAs for intra workout use?
EAAs (essential amino acids) include all nine amino acids the body can't produce itself — BCAAs (leucine, isoleucine, and valine) are just three of those nine. An EAA formula gives you the complete picture, while a BCAA product focuses specifically on those three branched-chain amino acids. For intra workout nutrition, many athletes prefer a full EAA product to cover all bases during training.
What intra workout supplement do you recommend?
THE EAA is a strong choice for anyone wanting comprehensive intra workout coverage — it contains 7g of Amino9® (a complete EAA blend) alongside 306mg of electrolytes, making it useful for both amino acid delivery and rehydration during training. Impact EAA is another well-regarded option, Informed Choice certified and built around all 9 essential amino acids, making it a solid pick for athletes who train at a competitive level.
What are intra workout carbs and do I need them?
Intra workout carbs are fast-digesting carbohydrate sources — typically maltodextrin or cyclic dextrin — taken during training to maintain glucose availability. They're most relevant for sessions lasting 60 minutes or more, where glycogen depletion becomes a real factor. Shorter sessions or those focused purely on strength work may not require carb supplementation mid-session, but endurance athletes and those doing high-volume training regularly include them in their intra workout routine.
What is the difference between maltodextrin and cyclic dextrin?
Both are fast-digesting carbohydrate sources commonly used as intra workout nutrition. Maltodextrin is a straightforward, cost-effective option that mixes easily and delivers a rapid supply of carbohydrates during training. Cyclic dextrin (also known as highly branched cyclic dextrin) has a higher molecular weight and is designed for rapid gastric emptying, meaning it passes through the stomach quickly — a preference for athletes who want to minimise any digestive discomfort during intense sessions.
Is an intra workout drink suitable for fasted training?
Fasted training means heading into your session without having eaten beforehand, which leaves circulating amino acid levels lower than they'd be post-meal. An EAA-based intra workout drink is a practical way to address this during the session itself. Products like Impact EAA or THE EAA are commonly used in exactly this context, providing a full spectrum of essential amino acids without requiring a full meal before training.
Are the intra workout products Informed Choice certified?
Impact EAA carries Informed Choice certification, meaning it's been tested for substances prohibited in sport — an important consideration for competitive athletes. If third-party testing is a priority for you, check individual product pages for certification details, as accreditation varies across the range.
Who developed the intra workout range?
The intra workout range has been developed by Myprotein's expert nutritionists, formulated to meet the specific demands of training mid-session. Each product is built around ingredients chosen for their relevance to athletic performance, with formats and flavours designed for practical use during workouts.
How do I use an intra workout drink?
Mix your chosen intra workout powder with water and sip it throughout your session rather than consuming it all at once. Start drinking in the first 15–20 minutes of training and continue through to the end. The exact amount will depend on the product — always follow the serving guidance on the label. Most intra workout powders are designed to mix cleanly in a standard shaker bottle.
Can I combine different intra workout products?
Yes — stacking an EAA product with a carbohydrate powder is a common approach, particularly for longer or higher-intensity sessions. For example, adding 100% Maltodextrin Carbs to a serving of an EAA formula gives you both amino acids and fast-acting carbohydrates in a single drink. Always check total serving sizes and follow individual product guidelines when combining supplements.
