What to Take After a Workout: Nutrition & Supplements

The most important things to take after a workout are protein, carbohydrates, and fluids. Getting all three within a few hours of training supports muscle repair, restores energy, and replaces what you lost through sweat. The specifics depend on whether you just finished a strength session or an endurance workout, but the core priorities are the same.

Protein: How Much You Actually Need

Protein after exercise provides the raw materials your muscles need to repair and grow. The target is 15 to 30 grams per serving. Eating more than about 40 grams in one sitting doesn’t appear to boost muscle repair any further, so there’s no benefit to chugging a massive shake.

What matters more than the total grams is the amino acid profile, specifically the amount of leucine. Leucine is the amino acid that flips the switch on muscle rebuilding. You need at least 2 to 3 grams of leucine in a meal to fully activate that process. Most servings of 20 to 30 grams of a quality protein source will get you there.

Whey protein isolate is considered the gold standard for post-workout recovery because it’s absorbed quickly and is naturally high in leucine. But plant-based protein powders (pea, soy, rice blends) work just as well for muscle growth, as long as they deliver similar amounts of protein and leucine per serving. Look for a powder with at least 20 to 30 grams of protein and 1 to 3 grams of leucine. Many plant blends now combine two or more sources to hit those numbers.

If you prefer whole food, a chicken breast, Greek yogurt, eggs, or a can of tuna will all land in that 20 to 30 gram range. The powder is a convenience, not a requirement.

Your Daily Protein Targets by Goal

Post-workout protein is one piece of a bigger picture. Your total daily intake matters more than any single meal. If you’re lifting weights to build muscle, aim for 1.5 to 1.7 grams of protein per kilogram of body weight per day. For a 75 kg (165 lb) person, that’s roughly 113 to 128 grams spread across the day. If you’re lifting to maintain muscle rather than grow, 1.0 gram per kilogram is sufficient.

Endurance athletes training at high intensity need 1.2 to 1.6 grams per kilogram daily. That protein isn’t primarily for building bigger muscles. It’s for repairing the tissue breakdown that happens during long runs, bike rides, or swims, and for preventing the energy crash that hits when your body starts burning muscle for fuel.

Carbohydrates: Refueling Your Energy Stores

Exercise burns through glycogen, the stored form of carbohydrate in your muscles and liver. Replacing it after training is what lets you perform well in your next session. The general recommendation for recovery is a 4:1 ratio of carbohydrates to protein. So if you’re eating 25 grams of protein, pair it with about 100 grams of carbohydrates.

This ratio matters most for endurance athletes, who deplete glycogen far more than someone doing a 45-minute lifting session. Endurance athletes need 6 to 10 grams of carbohydrates per kilogram of body weight per day. Strength athletes need less, typically 4 to 6 grams per kilogram, because resistance training doesn’t burn through glycogen stores at the same rate.

Good post-workout carbohydrate sources include rice, potatoes, oats, fruit, bread, or pasta. Combining them with your protein source in one meal is the simplest approach. A bowl of rice with chicken, a smoothie with banana and protein powder, or yogurt with granola and berries all check both boxes.

The “Anabolic Window” Is Wider Than You Think

You’ve probably heard you need to eat within 30 minutes of your last rep or your workout is wasted. That’s an exaggeration. The so-called anabolic window, the period when your body is primed to use nutrients for recovery, likely extends 5 to 6 hours around your training session, not just 30 to 60 minutes after.

Studies comparing people who ate protein immediately after training versus those who ate it hours later found similar changes in body composition and strength after 10 weeks. The one exception: if you train completely fasted (first thing in the morning with no food), the window tightens. In that case, eating soon after your workout becomes more important because your body has been without fuel for an extended period. If you had a meal one to three hours before training, you have more flexibility on the back end.

Hydration and Electrolytes

You lose fluid through sweat during every workout, and starting your recovery dehydrated slows everything else down. The guideline is to drink 16 to 24 ounces of fluid for every pound of body weight you lost during exercise. The extra volume beyond a simple one-to-one replacement accounts for the sweat and urine losses that continue after you stop moving.

For workouts under an hour, water alone is usually enough. Once sessions stretch past 60 minutes or involve intense intervals, especially in hot conditions, adding electrolytes becomes more important. Sodium is the primary electrolyte lost in sweat, but the amount varies enormously from person to person. Sweat sodium concentrations range from very low to very high, which is why a single “take X milligrams” recommendation doesn’t hold up well. If you notice white salt lines on your clothes or hat after training, you’re a heavier salt sweater and will benefit more from an electrolyte drink or adding salt to your post-workout meal.

Creatine

Creatine monohydrate is one of the most studied sports supplements, and the evidence for its benefits to muscle mass and strength is strong. You’ll often see advice to take it immediately after your workout, but the research doesn’t clearly support one timing over another. Taking creatine before exercise and after exercise both produce similar gains in muscle and performance over training periods of 5 to 12 weeks. One study has hinted at a slight edge for post-workout creatine when it comes to muscle growth, but the overall body of evidence doesn’t support strict timing prescriptions.

The practical takeaway: take your creatine whenever it’s easiest to remember. Consistency matters far more than the clock. A standard dose is 3 to 5 grams per day.

Tart Cherry Juice for Soreness

If muscle soreness after hard sessions is a recurring problem, tart cherry juice has some evidence behind it. The natural compounds in tart cherries help reduce the inflammation that causes delayed-onset muscle soreness. The most common dose studied is 30 mL of tart cherry juice concentrate, taken twice per day (60 mL total).

The catch is that this isn’t a one-time post-workout fix. The protocol that shows results involves drinking it daily for 3 to 7 days before a hard training session or event, plus 2 to 4 days afterward. It’s more of a recovery strategy around particularly demanding workouts or competitions than something you’d take after every gym visit.

Endurance vs. Strength: Different Priorities

After a long run, bike ride, or swim, carbohydrates are your top priority. You’ve burned through your glycogen stores and need to rebuild them for your next session. Protein still matters for repairing tissue, but the emphasis should tilt heavily toward carbs. That 4:1 carb-to-protein ratio is designed with endurance athletes in mind.

After a strength training session, protein takes the lead. Your primary goal is giving your muscles the amino acids they need to rebuild stronger. You still need carbohydrates, just not as aggressively. A balanced meal with a solid portion of protein and a moderate serving of carbs covers your bases. If you’re trying to build muscle, make sure your overall calorie intake is high enough to support those gains, because protein alone won’t do it if you’re in a calorie deficit.

For people doing a mix of both, like a CrossFit-style workout or a sport that combines running with bodyweight exercises, split the difference. Prioritize protein slightly, include plenty of carbohydrates, and rehydrate thoroughly. The fundamentals don’t change, only the ratios shift.
