Post workout supplements are where the real work begins. Training creates the stimulus — what you put back in afterwards determines how your body responds. The Recovery & Build range is built around that window after exercise, stocking the proteins and carbohydrates your muscles need when they need them most.
From fast-digesting whey to high-carb mass gainers, every product here is formulated by Myprotein's expert nutritionists with a clear purpose: giving you the nutritional foundation to train hard, recover, and come back stronger. Whether you're putting in the reps at the gym or logging miles on the road, post workout protein powder and targeted nutrition make the difference between going through the motions and actually progressing.
Who Recovery & Build Are For
These products are built for anyone who trains with a goal in mind. If you're lifting to add muscle mass, protein contributes to the growth and maintenance of muscle mass1 — and the range includes formats calibrated to deliver it precisely. Strength athletes, bodybuilders, and gym regulars putting in consistent sessions will find products here that fit directly into a structured nutrition plan.
Hard gainers and those in a deliberate mass-building phase will want to look at the higher-calorie options in the range. Impact Whey Mass Gainer delivers 30g of protein and 50g of carbohydrates per serving — a purposeful combination for those who need to eat more than their appetite allows. Endurance athletes and recreational trainers will find equally relevant options, particularly when it comes to replenishing what a long session takes out.
When to Use Recovery & Build
The post workout window is the primary use case here. After intensive or long-lasting physical exercise that leads to muscle fatigue and glycogen depletion, carbohydrates contribute to the recovery of normal muscle function2 — making the period immediately after training the logical time to use these products. Mixing a shake within 30–60 minutes of finishing a session is standard practice for most athletes.
That said, these aren't exclusively post workout supplements. Protein contributes to the maintenance of muscle mass1 throughout the day, so a shake between meals or first thing in the morning counts too. Mass gainers can also be used as a between-meal calorie source when daily intake needs a significant top-up. Timing matters, but consistency across the full day matters more.
Recovery & Build Benefits
Protein for Muscle Mass
Every product in this range is anchored in protein. Protein contributes to the growth and maintenance of muscle mass1 — that's the foundation the range is built on. Whether you're drawing that from hydrolysed whey isolate or a mass gainer blend, you're putting in the macronutrient that matters most after training.
Carbohydrates for Glycogen Replenishment
Carbohydrates are the body's primary fuel during exercise, and after a hard session, stores need replenishing. 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 muscle2. The mass gainer options in this range make it straightforward to hit meaningful carb targets alongside protein.
Informed Choice Certified Formulas
Clear Whey Protein Powder carries Informed Choice certification, meaning every batch is tested for banned substances. For competitive athletes training under anti-doping rules, that certification isn't optional — it's the minimum standard. It also signals a level of quality control that benefits any serious trainer.
Formats That Fit Your Routine
Post workout nutrition doesn't have a universal format, and neither does this range. Clear Whey Protein Powder delivers a lighter, juice-style shake built around hydrolysed whey isolate. Impact Whey Mass Gainer goes the other way — high protein, high carb, designed to make a caloric surplus more manageable. Two very different tools for two very different goals.

FAQs
What are post workout supplements and what's in them?
Post workout supplements are products formulated to take after exercise, typically centred around protein and carbohydrates — the two key macronutrients involved in refuelling after training. The Recovery & Build range includes protein powders made from hydrolysed whey isolate and mass gainers combining high protein with significant carbohydrate content. Protein contributes to the growth and maintenance of muscle mass1, while carbohydrates contribute to the recovery of normal muscle function after intensive exercise leading to glycogen depletion2.
What are the best post workout supplements for muscle building?
The best post workout protein powder for muscle building is one that delivers a meaningful protein dose consistently after training. Clear Whey Protein Powder provides 20g of protein per serving from hydrolysed whey protein isolate — a fast-digesting format that's light on the stomach and Informed Choice certified. For those aiming to add mass, Impact Whey Mass Gainer combines 30g of protein with 50g of carbohydrates per serving, making it easier to hit the caloric surplus that mass building requires.
What should I eat or drink after a workout?
Post workout nutrition should prioritise protein and carbohydrates. Protein contributes to the maintenance and growth of muscle mass1, and carbohydrates contribute to the recovery of normal muscle function after highly intensive exercise that depletes glycogen stores2. A protein shake taken within 30–60 minutes of finishing a session is a practical starting point, with the amount of carbohydrate depending on training intensity and your overall daily intake targets.
Is a post workout mass gainer different from a regular protein powder?
A post workout mass gainer is specifically formulated to deliver both high protein and high carbohydrates in a single serving, making it a more calorie-dense option than a standard protein powder. Impact Whey Mass Gainer, for example, provides 30g of protein and 50g of carbohydrates per serving — a combination designed for those who need a substantial nutritional top-up after training, particularly anyone working towards adding size.
How much protein do I need after a workout?
Individual protein needs vary depending on body weight, training volume, and overall dietary intake. Most guidance for active individuals points to spreading protein intake across the day rather than relying on a single large dose. Clear Whey Protein Powder delivers 20g per serving, which fits comfortably into a broader daily protein target. Total daily intake across all food and supplement sources is what counts most.
What is Informed Choice certification and why does it matter?
Informed Choice is a quality assurance programme that tests sports nutrition products for substances banned in competitive sport. Clear Whey Protein Powder carries this certification, meaning every batch is independently tested before it reaches customers. For athletes competing under anti-doping rules, that testing matters — it removes uncertainty about what's in the product. It also reflects a broader commitment to product quality that's relevant even for those who don't compete.
Who develops the Recovery & Build products?
The Recovery & Build range is developed by Myprotein's expert nutritionists, who formulate each product around specific training needs and nutritional targets. That means the macronutrient profiles, ingredient choices, and formats are purpose-built for post workout use rather than assembled generically. Informed Choice certification on products like Clear Whey Protein Powder adds a further layer of quality assurance on top of the in-house formulation process.
When is the best time to take after workout supplements?
After workout supplements are most commonly taken within 30–60 minutes of finishing a session, when the body has depleted fuel stores and protein intake is a practical priority. That said, protein contributes to the maintenance of muscle mass1 throughout the day — not just in the immediate post workout window. A consistent daily protein intake from food and supplements combined is more important than hitting an exact minute post-training.
Can I use recovery supplements on rest days?
Protein powder and mass gainers aren't exclusive to training days. Protein contributes to the maintenance of muscle mass1 regardless of whether a training session has taken place, and daily protein targets don't disappear on rest days. Using a shake to top up intake on lighter days is a practical approach, particularly for anyone who struggles to hit targets through food alone. Mass gainers can also serve as a calorie-dense meal supplement when appetite is lower.
What's the difference between Clear Whey Protein Powder and Impact Whey Mass Gainer?
Clear Whey Protein Powder is built around hydrolysed whey protein isolate, delivering 20g of protein per serving in a lighter, juice-style format — a good fit for those focused on protein intake without additional calories. Impact Whey Mass Gainer takes a different approach, combining 30g of protein with 50g of carbohydrates in a more calorie-dense serving designed for those pursuing a mass-building goal. The right choice depends on your overall caloric needs and what you're working towards.
1. Protein contributes to the growth and maintenance of muscle mass.
2. Carbohydrates contribute to the recovery of normal muscle function (contraction) after highly intensive and/or long-lasting physical exercise leading to muscle fatigue and the depletion of glycogen stores in skeletal muscle.
