Intra workout supplements are designed for one specific window — the session itself. While you're training, your body is burning through fuel, losing electrolytes through sweat, and calling on amino acids to keep working. Intra workout nutrition is about meeting those demands in real time, not before or after.
The range covers everything from fast-acting carbohydrate and electrolyte formulas to amino acid blends and electrolyte tablets, powders, and gummies — giving you flexible options whether you're 45 minutes into a gym session or two hours into an endurance event.
Who Intra Workout Supplements Are For
If your sessions run longer than an hour, or you train at high intensity and sweat heavily, intra workout nutrition is worth taking seriously. Endurance athletes, HYROX competitors, CrossFit athletes, and anyone doing back-to-back training days will find the most value here — but even shorter, intense sessions can warrant mid-session electrolyte intake.
These products are equally relevant for people who train fasted, those who find solid food uncomfortable during exercise, or anyone who wants a straightforward way to take in carbohydrates and electrolytes without stopping what they're doing. Format options — tablets, gummies, powders, gels — mean there's something that fits however you prefer to train.
When to Use Intra Workout Supplements
The clue is in the name — these are built for during your session. Electrolyte products are best sipped consistently throughout training rather than taken all at once. For carbohydrate formulas, starting intake around the 30–45 minute mark of a longer session is a common approach, giving your body a steady stream of fuel as glycogen stores begin to drop.
Amino acid products like BCAAs and EAAs are also commonly used mid-session, particularly during resistance training. They're typically mixed into water and consumed throughout the workout. Carbohydrate-electrolyte solutions enhance the absorption of water during physical exercise1, making them particularly useful when you're sweating hard and need to stay on top of fluid intake at the same time.
Intra Workout Benefits
Electrolyte Replenishment Mid-Session
Sweat isn't just water — it carries sodium, potassium, magnesium, and other electrolytes with it. Replenishing these during training, rather than waiting until after, keeps you on the right side of hydration throughout. Potassium contributes to normal muscle function2, and magnesium contributes to normal muscle function3 and electrolyte balance4 — both are commonly found in intra workout electrolyte formulas.
Carbohydrate Fuel for Longer Sessions
Carbohydrate-electrolyte solutions contribute to the maintenance of endurance performance during prolonged endurance exercise1. For sessions where glycogen depletion is a real factor — long runs, endurance events, high-volume training — having a source of carbohydrates mid-session means you're not running on empty before you're done.
Amino Acids During Training
BCAAs (leucine, isoleucine, and valine) and EAAs are among the most popular intra workout ingredients. These are the building blocks of protein, and many athletes choose to keep amino acid levels topped up throughout a session rather than relying solely on pre- or post-workout intake. Protein contributes to the growth and maintenance of muscle mass5 — and amino acids, as the building blocks of protein, are central to that process.
Flexible Formats for Any Training Style
From fast-dissolving tablets to sippable powders, gels, and gummies, intra workout products are built to be practical mid-session. No prep, no mess — just something that fits into the way you already train, whether that's in the gym, on the road, or on the competition floor.

FAQs
What are intra workout supplements?
Intra workout supplements are products formulated to be taken during exercise, rather than before or after. They typically contain electrolytes, carbohydrates, amino acids, or a combination of these — ingredients chosen to match what your body is using and losing during a training session. The format varies: powders, tablets, gummies, and gels are all available depending on what suits your training style.
What's the difference between intra workout powder and tablets?
Intra workout powder is typically mixed with water and sipped throughout a session, making it well suited to longer training blocks where you'd be drinking anyway. Tablets, like THE Electro Electrolyte Tablets, dissolve quickly and are a compact option when you don't want to carry a full shaker — each tablet delivers 500mg sodium. The right format comes down to how you prefer to train and how easy you need things to be mid-session.
What do intra workout supplements contain?
Most intra workout products are built around one or more of three core ingredients: electrolytes (typically sodium, potassium, and magnesium), carbohydrates (for fuel during longer sessions), and amino acids such as BCAAs or EAAs. Some formulas combine all three. Magnesium contributes to normal muscle function3 and electrolyte balance4, while potassium contributes to normal muscle function2 — these are staples in electrolyte-focused intra workout products.
What intra workout supplement do you recommend for endurance training?
For endurance-focused sessions, a carbohydrate and electrolyte formula is the most relevant choice. THE Electrofuel HYROX Carbohydrate and Electrolyte Powder is designed for exactly this kind of demand, delivering 650mg sodium alongside carbohydrates to fuel sustained effort. Carbohydrate-electrolyte solutions contribute to the maintenance of endurance performance during prolonged endurance exercise1 and enhance the absorption of water during physical exercise1, making this format a practical choice for long sessions.
Are intra workout supplements suitable for HYROX training?
HYROX events combine running and functional fitness over a significant duration, meaning fuel and electrolyte management mid-event is a real consideration. Several products in this range are specifically developed with HYROX athletes in mind — THE Electrofuel HYROX and THE Electro HYROX Electrolyte Powder are both built for that kind of high-output, longer-duration effort where consistent electrolyte intake matters.
Can I use intra workout supplements for shorter gym sessions?
Shorter sessions under an hour typically don't require carbohydrate loading mid-workout, but electrolyte intake can still be relevant — especially if you sweat heavily or train in a warm environment. A simple electrolyte tablet or a few gummies is a practical option for those sessions without overcomplicating your stack. Electrolyte gummies in a zesty lemon sherbet flavour are an easy way to get something in mid-set without breaking your rhythm.
What are BCAAs and EAAs, and why are they used intra workout?
BCAAs (branched-chain amino acids) are leucine, isoleucine, and valine — three of the nine essential amino acids. EAAs (essential amino acids) include all nine that the body can't produce on its own. Both are components of protein, and protein contributes to the growth and maintenance of muscle mass5. Many athletes choose to sip an amino acid formula throughout their session as part of their overall nutrition strategy.
Who developed Myprotein's intra workout range?
Myprotein's intra workout products are developed by Myprotein's expert nutritionists, who formulate each product with specific training demands in mind — from everyday gym sessions through to high-output endurance events. Ingredient choices and dosages are guided by the practical needs of athletes at different levels, not just what looks good on a label.
How do I choose between an electrolyte-only product and a carbohydrate-electrolyte formula?
The session length and your fuel strategy are the deciding factors. Electrolyte-only products, like THE Electro Electrolyte Tablets or Electrolyte Gummies, are suited to sessions where you're managing hydration but don't need additional carbohydrate intake. Carbohydrate-electrolyte formulas are built for longer, more demanding sessions where glycogen depletion becomes a factor and you need both fuel and fluid replenishment together.
What formats are available across the intra workout range?
The intra workout range covers a broad set of formats — powders you mix into a shaker, fast-dissolving tablets, convenient gummies, and ready-to-mix gels. There are also amino acid options in both powder and tablet form, covering BCAAs and EAAs. That breadth means whether you want something that fits in a pocket for race day or a powder you prep at home, there's a format that works.
