Post workout supplements are designed for the window after training when your body needs the right nutrients most. Whether you've just finished a heavy lifting session, a long run, or a high-intensity class, what you put in after matters — and getting that intake right starts with choosing the correct format and formula for your goals.
At Myprotein, the post workout range covers everything from high-protein powders to mass gainers and collagen formulas — all developed by expert nutritionists to fit different training styles and targets. Protein contributes to the growth and maintenance of muscle mass1, making it a cornerstone of any post-workout nutrition plan.
Who Post Workout Supplements Are For
Anyone who trains regularly and wants to be intentional about their nutrition after exercise will find something useful here. That includes those working towards building size — where something like Impact Whey Mass Gainer, with 30g of protein and 50g of carbs per serving, fits the brief — as well as those focused on general fitness who want a reliable, high-protein option they can mix quickly and take on the go.
Post workout supplements aren't just for those chasing muscle. If you prioritise overall wellbeing and structural health, Collagen Protein Powder delivers up to 26g of hydrolysed collagen peptides per serving, with Type I and III — the types most abundant in skin and connective tissue. Whatever your training background, there's a post workout format here built around it.
When to Use Post Workout
Timing matters when it comes to post workout nutrition. Most people aim to consume their post workout supplement within 30 to 60 minutes of finishing a session, when the body is primed to use incoming nutrients. A protein shake or mass gainer mixed with water or milk is one of the most convenient ways to hit that window without overthinking it.
Carbohydrates taken after highly intensive or long-lasting physical exercise contribute to the recovery of normal muscle function after glycogen stores have been depleted2. That's why options like Impact Whey Mass Gainer — which combines protein with 50g of carbs per serving — are a practical fit for those coming off demanding training sessions where both nutrients are needed.
Post Workout Benefits
High Protein Intake Made Simple
Post workout supplements make it straightforward to hit meaningful protein numbers after training. Protein contributes to the maintenance of muscle mass1, and having a ready-to-mix formula on hand means you're not scrambling for a meal the moment you finish your session. Impact Diet Whey delivers up to 36g of protein per serving — one of the highest options in the range.
Carbohydrate Replenishment After Intense Training
For those coming off high-volume or endurance-focused sessions, carbohydrates play a key role. 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. Mass gainers in this range are built with this in mind, combining carbs and protein in a single serve.
Flexible Formats for Different Routines
From lean protein powders to collagen-based formulas and mass gainers, the range spans a variety of formats so you're not locked into one approach. Each product is available in multiple flavours, and most mix easily with water or milk — keeping your post-workout routine as low-friction as possible.
Formulated by Myprotein Nutritionists
Every product in the post workout range is developed by Myprotein's expert nutritionists. That means the formulas are built around real training needs — not just trend-driven ingredients — so you know there's genuine expertise behind what's in the tub.

FAQs
What are post workout supplements?
Post workout supplements are nutritional products taken after exercise to help meet the body's increased demand for protein and carbohydrates following training. They typically come in powder form and are mixed with water or milk for a quick serve. Common formats include whey protein, mass gainers, and collagen powders — each designed around different training goals and dietary preferences.
What is the best post workout supplement?
The right post workout supplement depends on your goals. For those focused on building size, Impact Whey Mass Gainer offers 30g of protein and 50g of carbs per serving — a practical combination after high-volume training. For a leaner, high-protein option, Impact Diet Whey delivers up to 36g of protein per serving. Protein contributes to the growth and maintenance of muscle mass1, so the best starting point is a formula that gets your protein numbers where they need to be.
When should I take a post workout supplement?
Most people take their post workout supplement within 30 to 60 minutes of finishing a training session. A protein powder or mass gainer mixed with water or milk is a quick, convenient way to hit this window. If you've completed a particularly long or intense session, pairing protein with carbohydrates makes sense — carbohydrates contribute to the recovery of normal muscle function after physical exercise that leads to glycogen depletion2.
What's the difference between a post workout protein powder and a mass gainer?
A standard post workout protein powder prioritises protein with minimal carbs and calories — ideal for those who want to meet their protein targets without significantly adding to their calorie intake. A mass gainer combines protein with a higher carbohydrate content, making it a better fit for those looking to increase overall calorie intake alongside their training. Impact Whey Mass Gainer, for example, delivers 30g of protein and 50g of carbs in a single serving.
Can I use a post workout supplement as a meal replacement?
Post workout supplements aren't formulated as complete meal replacements — they're designed to complement your diet by covering specific nutrient targets after training. That said, some people choose to blend their protein powder with additional ingredients like oats, nut butter, or fruit to create a more complete post-training meal. For a standalone meal replacement, look specifically at products formulated for that purpose.
What is collagen protein and how does it differ from whey?
Collagen protein is derived from animal connective tissue and is composed of a distinct amino acid profile compared to whey. Collagen Protein Powder delivers up to 26g of hydrolysed collagen peptides per serving, featuring Type I and III — the types most abundant in skin and connective tissue. Whey protein, on the other hand, is a dairy-derived complete protein commonly used for its contribution to muscle mass growth and maintenance1. Both have their place depending on what you're prioritising post-training.
How much protein do I need after a workout?
General guidance from nutrition research suggests somewhere in the range of 20–40g of protein per serving as a practical post-workout target for most active adults, though individual needs vary based on body weight, training intensity, and overall daily intake. Products like Impact Diet Whey, with up to 36g of protein per serving, are positioned to cover this effectively. Protein contributes to the maintenance of muscle mass1, so getting consistent daily intake matters more than any single serve in isolation.
What post workout supplements does Myprotein offer?
The Myprotein post workout range currently includes Impact Whey Mass Gainer, Collagen Protein Powder, Impact Diet Whey, and Total Protein Blend. These span different formats — from high-carb mass gainers to hydrolysed collagen peptide powders — covering a range of post-training nutrition goals. All are available in multiple flavours and mix easily with water or milk.
Who develops Myprotein's post workout supplements?
Myprotein's post workout supplements are developed by Myprotein's expert nutritionists. Each formula is built around the specific demands of post-training nutrition, drawing on ingredient research and practical performance considerations — not just marketing trends.
How do I choose the right post workout supplement for my goal?
Start with your primary training goal. If you're focused on gaining size, a mass gainer with combined protein and carbohydrates — like Impact Whey Mass Gainer — is a logical choice. If you're prioritising lean protein intake, Impact Diet Whey's up to 36g per serving makes it a high-output option. For those with a specific interest in collagen peptides, Collagen Protein Powder offers up to 26g of hydrolysed Type I and III collagen per serving. Matching the format to the goal is the clearest way to choose.
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.
