What Should You Take After the Gym? A Recovery Stack That Works

What to take after the gym and why: how much protein, when creatine works, whether you need electrolytes, when carbs matter, what to leave out, and what a recovery stack costs per day with Prozis and Protein Works.

Quick answer

After the gym you need three things: 20 to 40g of protein, 3 to 5g of creatine at any time of day, and enough fluid and salt to replace what you sweated out. Carbohydrate only needs priority if you train again within about four hours. The simplest stack is Prozis Supreme Whey Protein plus Prozis Creatine Monohydrate, which costs about £1.44 a day with code WHEYWISE for a 30g scoop and 5g of creatine. BCAAs are the supplement to leave out: on their own they show no muscle-building effect in human studies, and a whey shake already contains them.

A recovery stack is the short list of things that help you recover between training sessions, and most of it is food, not supplements. This guide covers what the research supports after a gym session, how much of each you need, what you can skip, and what the supplement part costs per day.

What should you take after the gym?

After the gym, take 20 to 40g of protein, keep up 3 to 5g of creatine a day, and replace the fluid and salt you sweated out. Carbohydrate matters most when your next session is within four hours. Everything else is optional.

How much protein do you need after a workout?

You need about 0.25g of protein per kg of body weight after a workout, which is 20 to 40g for most adults, according to the International Society of Sports Nutrition position stand on protein (Jäger et al., 2017, PMID 28642676). In one study of 48 men, 20g of whey was enough to maximise muscle protein synthesis after leg training, and 40g mostly raised the amount of protein burned for energy (Witard et al., 2014, PMID 24257722).

Timing matters less than total intake. A meta-analysis of more than 20 studies found that, once total daily protein was accounted for, protein timing had no significant effect on muscle or strength gains (Schoenfeld et al., 2013, PMID 24299050). Aim for 1.4 to 2.0g of protein per kg of body weight across the day, spread over meals every three to four hours, and treat the post-workout shake as an easy way to reach that total. For which protein suits recovery best, see our guide to the best protein for muscle recovery.

Should creatine be part of a recovery stack?

Yes, if you lift weights: creatine monohydrate is one of the few supplements with strong evidence behind it. The International Society of Sports Nutrition recommends 3 to 5g a day, found no compelling evidence of harm at up to 30g a day for five years, and reports weight gain as the only consistent side effect (Kreider et al., 2017, PMID 28615996). Its position stand also cites faster strength recovery after muscle-damaging exercise in creatine users.

When you take it does not matter much. A 2022 review of the timing studies found small effects at most and could not name a best time (Candow et al., 2022, PMID 35669557), so add it to your shake or take it with breakfast. Without a loading phase, 3 to 5g a day fills your muscle stores in three to four weeks. For dosing in detail, see how much creatine per day, and for putting it in the same shake, mixing creatine with protein powder.

Do you need electrolytes after training?

After a normal gym session, water and your next meal replace what you lost, so you do not need an electrolyte drink. After long, hot or very sweaty sessions, electrolytes help. In a study of 506 athletes, sweat carried about 36 mmol of sodium per litre on average, at about 1.2 litres an hour (Baker et al., 2016, PMID 26070030), which is roughly 1g of sodium an hour, with wide variation between people.

To rehydrate fully, drink about 150% of the fluid you lost, with some sodium. In a controlled study, men who drank 150% of their sweat loss stayed in fluid balance, and drinks with more sodium were kept rather than lost as urine (Shirreffs et al., 1996, PMID 8897383). Milk was also retained better than water in a 2016 study of 72 men (Maughan et al., 2016, PMID 26702122), so a whey shake made with milk does double duty. Weigh yourself before and after a long session: each kg lost is about a litre of sweat.

For long or sweaty sessions

Pros

  • Isotonic carbohydrate drink powder, for fluid and fuel in one
  • 800g tub at £12.72, or £11.45 with code WHEYWISE
  • Useful after long sessions where you need carbohydrate as well as fluid

Cons

  • Not needed after a normal gym session
  • Adds sugar and calories you do not need on rest days

When do carbs matter for recovery?

Carbohydrate matters for recovery when you train again within about four hours, because muscle glycogen has to be refilled quickly. In that case, aim for 1.0 to 1.2g of carbohydrate per kg of body weight per hour for the first four hours (Podlogar and Wallis, 2022, PMID 36173597), or about 0.8g per kg per hour with 0.2 to 0.4g of protein per kg per hour (Kerksick et al., 2017, PMID 28919842). If your next session is tomorrow, the total carbohydrate you eat over the day matters more than when you eat it.

What can you leave out of a recovery stack?

Leave out BCAAs if you already eat enough protein. A 2017 review found no human study showing that BCAAs on their own build muscle (Wolfe, 2017, PMID 28852372), and a whey shake already contains them. Tart cherry juice has modest evidence: a 2021 meta-analysis of 14 studies found a small effect on soreness and a moderate effect on strength recovery (Hill et al., 2021, PMID 33440334), so it is optional at best.

How much does a recovery stack cost per day?

The core of a recovery stack costs about £1.44 a day with Prozis and code WHEYWISE: a 30g scoop of Prozis Supreme Whey Protein from the 907g pouch costs about £1.17, and 5g of Prozis Creatine Monohydrate from the 300g tub costs 27p.

Prozis UK prices less the 10% WHEYWISE code. For cheaper protein per gram, compare all wheys on the whey comparison, and creatine on the creatine comparison.

What does a simple post-workout routine look like?

A simple routine is one shake and one habit. Mix a scoop of whey with water or milk after training, add your 5g of creatine to the same shaker, drink to thirst over the next few hours, and eat a normal meal with carbohydrate and protein. If you train fasted or late in the evening, a slow-digesting protein such as Prozis 100% Real Casein before bed is an option: the ISSN suggests 30 to 40g of casein before sleep (Jäger et al., 2017).

  1. Straight after training: 20 to 40g of protein, plus your 3 to 5g of creatine.
  2. Over the next few hours: water to thirst, more after a long or sweaty session.
  3. At your next meal: carbohydrate and protein, with salt as normal.
  4. If you train again within four hours: carbohydrate straight away.

For runners and endurance athletes, where carbohydrate and sodium matter far more, see our marathon nutrition guide.

Bottom line: a recovery stack is protein, creatine, and fluid with salt. Prozis Supreme Whey Protein and Prozis Creatine Monohydrate cover the supplement part for about £1.44 a day with code WHEYWISE. Skip BCAAs and spend the money on protein instead.

Frequently asked questions

What is the best thing to take after a workout?

A protein shake with 20 to 40g of protein is the most useful single thing to take after a workout, as part of a daily protein total of 1.4 to 2.0g per kg of body weight. Add 3 to 5g of creatine a day if you lift, and replace sweat losses with fluid and some salt.

Should you take creatine before or after a workout?

It makes little difference. The International Society of Sports Nutrition gives no timing advice, and a 2022 review of the timing studies found small effects at most and could not name a best time. Take 3 to 5g every day, whenever you will remember it.

Do you need electrolytes after the gym?

Usually not after a normal gym session, where water and your next meal replace what you lost. Electrolytes help after long or hot sessions with heavy sweating: sweat carries about 36 mmol of sodium per litre on average, and drinking about 150% of the fluid you lost, with sodium, restores balance better than water alone.

Are BCAAs worth taking for recovery?

Not if you already eat enough protein. A 2017 review found no human study showing that BCAAs on their own build muscle, and whey already contains them. Spend the money on protein instead.

How much does a recovery stack cost?

A 30g scoop of Prozis Supreme Whey Protein plus 5g of Prozis Creatine Monohydrate costs about £1.44 a day with code WHEYWISE: about £1.17 for the protein and 27p for the creatine. Water and food cover the rest for most gym sessions.
