Best Supplements for Recovery: 6 Ranked by Evidence, With Trial Doses

You trained hard yesterday, and today your legs feel like they belong to someone older. The supplement aisle has an answer for that, usually several. Recovery blends, amino acid drinks, glutamine, magnesium, fish oil, cherry concentrate. Most promise faster recovery and few say what that means or how much.

It's easy to feel like you're doing recovery wrong if your cupboard doesn't look like a pharmacy. You aren't. Most of what helps you recover is free, and the supplements that do work have specific, modest effects that only show up when the basics are in place.

This guide ranks supplements for workout recovery by the strength of the human trial evidence, gives the doses the studies used, and is honest about what each one does. Some speed the return of strength, some only dull soreness, and some do neither. For the free habits that matter more, our guide on how to recover faster from a workout ranks sleep, food, movement and the recovery tools.

Muscle Recovery Supplements Ranked by Evidence

Recovery here means getting your strength and performance back after hard training, not just feeling less sore. Those two can come apart, and several supplements on this list help one without the other.

1. Protein: The Best Supplement for Muscle Recovery

Protein supplies the amino acids your muscles use to repair and rebuild after training, and it has the largest pooled trial base of any recovery supplement. Pearson, Hind and Macnaughton (2023) reviewed 29 studies in the European Journal of Clinical Nutrition and pooled the trials of protein taken around muscle-damaging resistance exercise. Protein preserved isokinetic strength at 24, 48 and 72 hours and isometric strength at 96 hours, and lowered creatine kinase, a blood marker of muscle damage, at 72 hours. It had no effect on soreness.

So protein helps the part of recovery you can measure on the next session, even if you still feel stiff. Over months, it also drives adaptation. Morton and colleagues (2018) pooled 49 trials with 1,863 participants and found protein supplements improved strength and muscle gains from training, with no extra muscle beyond a total of about 1.62 grams per kilogram of body weight a day.

How to use it: aim for about 0.4 grams per kilogram per meal, which is roughly 25 to 40 grams for most adults, spread across three or four meals. Food covers this for most people. A shake is useful when a meal falls short or appetite is low after training.

2. Tart Cherry: Best for Hard Events and Race Weekends

Tart cherries, usually the Montmorency variety, are rich in anthocyanins, plant compounds with antioxidant and anti-inflammatory effects. Hill, Keane, Quinlan and Howatson (2021) pooled 14 studies in the International Journal of Sport Nutrition and Exercise Metabolism. Tart cherry had a small effect on soreness (effect size -0.44), a moderate effect on strength recovery (-0.78) and a large effect on recovery of jump height (-0.82). It lowered two inflammation markers slightly but didn't change creatine kinase.

The trial that started this line of research was Howatson and colleagues (2010). Twenty recreational marathon runners drank tart cherry juice or a placebo for five days before the race, on race day and for 48 hours after. Strength came back faster in the cherry group, and inflammation markers were lower.

How to use it: most positive trials used about 480 ml of tart cherry juice a day in two servings, or about 30 ml of concentrate twice a day. Start four to five days before the hard event and continue for two days after. Save it for races, tournaments and brutal training weeks. It adds sugar, and no trial has shown it helps muscle growth from regular lifting.

3. Omega-3 Fish Oil: Real Effects After Several Weeks

The omega-3 fats in fish oil, EPA and DHA, are built into muscle cell membranes over weeks and help resolve inflammation. The evidence for recovery is positive but softer than for protein. A 2026 meta-analysis in Nutrients by Yaghoobi and colleagues pooled nine placebo-controlled trials of muscle-damaging exercise. Omega-3 reduced soreness (effect size -0.75), creatine kinase and swelling, and improved strength (+0.45) and range of motion at the point of peak damage. The authors couldn't work out an effective dose from the trials.

Two other findings keep the effect in proportion. Lv and colleagues (2020) pooled 12 trials and found soreness fell by 0.93 points on a 10-point scale, which is below the 1.4 points people usually notice. On dose, VanDusseldorp and colleagues (2020) gave 32 trained men 2, 4 or 6 grams of fish oil a day for about seven and a half weeks. Only the 6-gram group had less soreness than placebo at 24, 48 and 72 hours, and its jump height recovered fastest.

How to use it: a separate 2026 meta-analysis by Li and Zhang in The FASEB Journal found the clearest effects at 2 grams or more of combined EPA and DHA a day for at least six weeks. That's EPA plus DHA, not total fish oil, so check the label. Oily fish raises your intake too, though 2 grams a day is more than most diets supply from food.

4. Creatine: Better for Training Capacity Than for Repair

Creatine is the best-supported supplement for building strength and muscle over months, and that's why it's on this list. For recovery from muscle damage specifically, the evidence is weaker than its reputation. Northeast and Clifford (2021) pooled 13 trials with 278 people and found creatine didn't speed the return of strength or reduce soreness, inflammation or stiffness at any point up to 96 hours. It lowered creatine kinase at 48 hours and nowhere else.

Individual trials show why the idea persists. In Cooke and colleagues (2009), 14 untrained men took creatine or a placebo before and after an eccentric leg workout, and the creatine group had 10 to 21 percent higher strength during recovery. Creatine also helps refuel. In Roberts and colleagues (2016), 14 men who cycled to exhaustion and then took creatine with a high-carbohydrate diet stored more muscle glycogen than placebo within the first day.

How to use it: 3 to 5 grams of creatine monohydrate a day, every day, is the dose in the International Society of Sports Nutrition position stand (Kreider 2017). Our breakdown of how much creatine you should take covers loading, body weight and timing.

5. Vitamin D: Only Worth It If Your Level Is Low

Vitamin D is the vitamin with the most direct recovery evidence. Owens and colleagues (2015) gave 20 men with insufficient vitamin D either 4,000 IU a day or a placebo for six weeks, then had them do a hard eccentric leg workout. The vitamin D group recovered more strength at 48 hours and seven days. Barker and colleagues (2013) saw about 8 percent better force recovery at 24 hours with the same dose in active men whose levels were already in the sufficient range, with no change in soreness.

How to use it: get your blood level tested if you train indoors, live far from the equator or rarely get sun. If it's low, the trials used 4,000 IU a day, which is the adult upper limit listed by the NIH Office of Dietary Supplements. More isn't better.

6. Caffeine: Dulls Soreness, With Mixed Results

Caffeine doesn't repair muscle, but it can make sore muscles hurt less. Maridakis and colleagues (2007) gave nine women 5 mg per kg of caffeine one and two days after a damaging leg workout, and pain during a maximal contraction fell by 48 percent. Hurley and colleagues (2013) found less soreness on days two and three in nine men. But Al-Nawaiseh and colleagues (2022) gave 11 runners 5 mg per kg two days after a downhill run and found no benefit for soreness or 5 km performance.

Caffeine also speeds glycogen refill. Pedersen and colleagues (2008) found that 8 mg per kg taken with carbohydrate refilled glycogen 66 percent faster over four hours. That's about 600 mg for a 75 kg person, above the 400 mg a day the FDA considers safe for most adults, so it only makes sense for athletes with two hard sessions in a day.

How to use it: a coffee or two the morning after a hard session is a reasonable way to take the edge off soreness. Keep it well away from bedtime, because the sleep you lose will cost more recovery than the caffeine gives back.

What Doesn't Work: BCAAs, Glutamine and Magnesium

BCAAs, if you already eat enough protein

BCAAs are three of the nine essential amino acids, leucine, isoleucine and valine. On their own they nudge muscle building. Jackman and colleagues (2017) found 5.6 grams after training raised muscle protein synthesis by 22 percent compared with placebo. But muscle needs all nine essential amino acids to build new protein, as Wolfe (2017) laid out, and a 25-gram serving of whey protein already carries about 5 grams of BCAAs, based on the amino acid analysis by Gorissen and colleagues (2018). A 2019 meta-analysis by Fedewa and colleagues did find BCAAs reduced soreness, but it pooled just 61 people across eight studies. If you eat enough protein, BCAAs are paying twice for the same thing.

Glutamine

Glutamine is the most abundant free amino acid in the body, and it's sold for recovery and growth. Candow and colleagues (2001) gave 31 young adults a large daily dose during six weeks of resistance training and found no difference from placebo in strength or lean mass. One small crossover trial, Legault and colleagues (2015), found 16 people recovered strength a little faster and felt less sore on 0.3 grams per kg a day, which is about 22 grams for a 75 kg adult. That's thin support for a big daily dose.

Magnesium, unless you're low

Magnesium shows up on most recovery lists, but recovery trials in people who aren't deficient are scarce. The best-known claim, that it prevents cramps, didn't hold up: a 2020 Cochrane review by Garrison and colleagues concluded magnesium is unlikely to give older adults meaningful protection from muscle cramps. If a blood test shows you're low, fixing that is worth doing for its own sake.

What Matters More Than Any Supplement

Every supplement above works at the margins of two bigger things: food and sleep.

Food. Recovery runs on energy. If you're eating far below your needs, protein and creatine can't make up the gap. After long or sweaty sessions, carbohydrate refills glycogen and fluid replaces sweat, and our guide to the recovery drink after a workout gives the amounts by session type, including when plain water is enough.

Sleep. This is where the biggest effect sits. Lamon and colleagues (2021) kept 13 young adults awake for one night and compared them with a normal night. The next day, muscle protein synthesis was 18 percent lower, cortisol was 21 percent higher and testosterone was 24 percent lower. No supplement on this list has shown an effect that large.

Which Recovery Supplements Do You Actually Need?

Most people need fewer than they think. Match the list to how you train:

• You lift three or four times a week. Enough protein, mostly from food, plus 3 to 5 grams of creatine a day. That's the whole list for most people.
• You have a race or tournament coming up. Add tart cherry for four to five days before and two days after, and plan your carbohydrate around the event.
• You rarely eat oily fish. Omega-3 at about 2 grams of EPA plus DHA a day is reasonable, but give it six weeks.
• You train indoors and rarely get sun. Test your vitamin D before buying any.
• You train twice a day. Carbohydrate and protein between sessions matter most. Creatine helps refill glycogen.

The Bottom Line

The best supplements for recovery are boring ones. Protein and creatine cover most lifters, tart cherry and omega-3 earn a place around hard events or when your diet lacks them, and vitamin D only matters if you're low. Nothing in a tub replaces sleep, and nothing replaces showing up again on the next training day.

That last part is where most people actually stall. Recovery only pays off if there's a next session to recover for. As Katie put it, "I've tried everything. This is the first time I've stuck with something past two weeks." If you'd rather have your training days and rest days laid out for you, see what a personalized training program looks like. FitCraft builds it around dumbbell and bodyweight training, adjusts your workouts as you progress and keeps a streak going so the next session actually happens.
