Intra Workout Supplements

Intra Workout Supplements at Myprotein

Intra workout supplements are designed to be taken during exercise — keeping your body fuelled, hydrated, and performing at its best through every rep, set, and kilometre. Whether you're an endurance athlete grinding through a long run or a lifter pushing through a heavy session, what you put in mid-workout matters. This range covers everything from carbohydrate gels and electrolyte tablets to amino acid formulas and carbohydrate-electrolyte powders, giving you the tools to train the way you want.

There are 19 products in this range, spanning multiple formats — tablets, powders, sachets, gels, and gummies — so you can find something that fits your session, your sport, and your routine. Every product is developed by Myprotein's expert nutritionists to deliver clean, precise nutrition when you need it most.

Who Intra Workout Supplements Are For

These products are built for anyone who trains with intent. Endurance athletes — runners, cyclists, triathletes, HYROX competitors — rely on intra workout carbohydrates and electrolytes to stay fuelled through prolonged efforts. Carbohydrate-electrolyte solutions contribute to the maintenance of endurance performance during prolonged endurance exercise¹, making them a staple for anyone racing or training at sustained intensity.

Strength and gym athletes will find value here too. Amino acid formulas like EAAs and BCAAs are a popular mid-session choice for those focused on resistance training, while electrolyte tablets are useful during any session where sweat loss is significant. If you train hard and want to stay topped up from warm-up to cool-down, this range is for you.

When to Use Intra Workout Supplements

Timing is straightforward — these supplements are designed to be used during your workout, not before or after. For sessions lasting longer than 60–90 minutes, carbohydrate intake mid-session becomes particularly relevant. Gels and carbohydrate-electrolyte powders are easy to consume on the move, making them well-suited to endurance events and long training blocks.

Electrolyte products come into their own during any session where you're sweating heavily — hot weather, high-intensity intervals, or prolonged cardio all increase fluid and mineral losses. Amino acid formulas can be sipped throughout a weights session or used alongside cardio. The format you choose — tablet, gel, powder, or gummy — often comes down to personal preference and practicality during your specific type of training.

Intra Workout Supplements Benefits

Rapid Carbohydrate Delivery

Carbohydrates are the body's primary fuel source during exercise. Products like energy gels and carbohydrate-electrolyte powders provide fast-acting carbs mid-session, with carbohydrates contributing 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 muscle². The 2:1 maltodextrin to fructose ratio used in some products is designed for efficient absorption during back-to-back fuelling.

Electrolyte Replenishment

Sweating depletes key minerals including sodium, potassium, and magnesium — all of which play roles in normal muscle and nerve function. Magnesium contributes to normal muscle function³ and potassium contributes to normal muscle function³, while carbohydrate-electrolyte solutions enhance the absorption of water during physical exercise⁴. Electrolyte tablets, powders, and gummies make it easy to replenish these minerals without interrupting your session.

Amino Acid Availability

EAAs (essential amino acids) and BCAAs (branched-chain amino acids — leucine, isoleucine, and valine) are naturally found in protein. Protein contributes to the growth and maintenance of muscle mass⁵. Many athletes include amino acid products as part of their intra workout stack, particularly during resistance training sessions where protein intake timing is a priority.

Flexible Formats for Every Sport

From fast-dissolving tablets and ready-to-mix powders to portable gels and grab-and-go gummies, the range caters to different sports and training styles. Sachets and gels suit on-the-move endurance athletes. Tablets dissolve quickly in water for minimal prep. Powders offer the most customisable dosing. Whatever your session looks like, there's a format that works with it.

FAQs

What are intra workout supplements?

Intra workout supplements are products formulated specifically to be consumed during exercise. They typically contain carbohydrates, electrolytes, amino acids, or a combination of these, and are designed to be easy to consume mid-session — in formats like gels, powders, tablets, and gummies. Unlike pre-workout or post-workout supplements, intra workout products are intended to keep you going through your training rather than preparing you for it or supporting you after it.

What's the difference between intra workout powder and intra workout tablets?

Intra workout powders are mixed with water and consumed as a drink during training — useful if you prefer sipping throughout a session and want flexible dosing. Tablets, like electrolyte tablets, dissolve quickly in water and offer a more compact, portable option with less preparation. Gels are the most convenient for on-the-move use, particularly during endurance events where stopping to mix a drink isn't practical. The right format comes down to your training environment and personal preference.
