Small extra gain: 0.30 kg more fat-free mass over training programmes (SMD 0.22), with no further benefit above roughly 1.6 g/kg/day total protein.[1][2][3]
Two large meta-analyses of RCTs (49 studies, 1,863 participants; 74 RCTs) agree that added protein increases lean mass during resistance training, with moderate-level evidence. The effect is small and plateaus once daily intake is adequate.
Each plate is one paper. Taller = stronger study design, wider = more studies pooled. Tap one.
Eating more protein gives small extra gains in lean mass and lower-body strength during resistance training, a slight bench-press benefit, and unclear effects on grip strength.
Protein supplementation significantly increased gains in muscle strength and size during prolonged resistance training in healthy adults, with no further benefit above about 1.6 g/kg/day.
A daily intake of 1.4-2.0 g/kg is sufficient for most exercisers to build and maintain muscle; supplements are a practical way to reach this, with 20-40 g doses spread across the day.
Small strength boost: 2.49 kg more on one-rep max over a training programme, with slight gains in lower-body and bench-press strength rated low-certainty.[1][2][4]
Meta-analyses show a statistically significant but small effect; Nunes 2022 rated the strength evidence as low level, and a 2026 analysis found significant performance effects only in trials that did not match calories between groups. Consistent direction but limited certainty fits Grade B.

Protein supplements' benefits for performance and recovery appear limited: all significant effects came from trials where calorie intake was not matched, so benefits may not be due to protein itself.
Eating more protein gives small extra gains in lean mass and lower-body strength during resistance training, a slight bench-press benefit, and unclear effects on grip strength.
Protein supplementation significantly increased gains in muscle strength and size during prolonged resistance training in healthy adults, with no further benefit above about 1.6 g/kg/day.
Mixed: with resistance training, one meta-analysis found extra lean mass (SMD 0.58) and leg strength (SMD 0.69), but a larger whey analysis found no lean-mass gain and only a small lower-body strength gain (SMD 0.25).[5][6][7][8]
Meta-analyses of RCTs in adults 60+ agree protein plus resistance training helps lower-body strength, but disagree on lean mass; whey without training showed no benefit. Older adults also need more protein per meal. Real caveats fit Grade B.
Each plate is one paper. Taller = stronger study design, wider = more studies pooled. Tap one.
In adults 60+, whey did not improve grip strength, physical performance or lean mass overall; with resistance training it modestly improved lower-body strength.
In older adults (mean age 73) doing resistance training, protein supplements added lean mass and leg strength compared with training alone.
PROT-AGE expert group recommends adults over 65 eat at least 1.0–1.2 g/kg/day, at least 1.2 g/kg if active, except those with severe kidney disease.
Pooled lab data showed older men (~71 y) needed about 0.40 g/kg protein per meal to max out muscle protein synthesis, versus 0.24 g/kg in younger men.
Does not reduce muscle soreness; some pooled data show better preservation of strength in the 24-96 hours after hard lifting, but results are inconsistent.[9][10][11]
Pearson 2023 found no effect on soreness, a systematic review found no measurable reduction in muscle damage or faster recovery, and positive strength-recovery findings come from small, methodologically varied studies. Conflicting evidence is Grade C, Not Backed.
Each plate is one paper. Taller = stronger study design, wider = more studies pooled. Tap one.
Protein around exercise may help maintain maximal strength and lower creatine kinase after resistance exercise, but did not reduce muscle soreness.
Pooled data from 13 RCTs showed small-to-medium benefits of whey for restoring muscle function from under 24 to 96 hours, though only half of studies individually found a benefit.
There is insufficient evidence that protein after exercise reduces soreness or muscle damage; acute anabolic effects have not translated into measurably faster recovery.
Protein powders are concentrated milk proteins (whey, casein) or plant proteins (soy, pea) used to top up dietary protein from foods like meat, fish, eggs and dairy. US adults aged 19–30 average 88.2 g of protein a day, and adults overall about 1.10–1.32 g per kg of ideal body weight (Berryman 2018), below the 1.4–2.0 g/kg the ISSN suggests for people who train (Jäger 2017).
Protein supplies essential amino acids, especially leucine, which switch on muscle protein synthesis. Resistance exercise and protein work together: training makes muscle more responsive to protein for at least 24 hours. Repeated meals that push synthesis above breakdown add up to muscle growth over weeks.[3]

20–40 g per serving (about 0.25 g/kg), toward a daily total of 1.4–2.0 g/kg
Maximally stimulated muscle protein synthesis after leg exercise in young men; 40 g mostly increased oxidation.[13]
40 g stimulated more muscle protein synthesis (0.059 vs 0.049 %/h).[14]
100 g gave a bigger and longer (>12 h) anabolic response, so large meals are not 'wasted'.[15]
Extra fat-free-mass gains level off at about 1.62 g/kg/day; one review treats 2.2 g/kg/day as the upper end of useful intake.[1][12]
May be needed to best preserve lean mass during calorie restriction.[3]
Timing. Total daily protein matters far more than timing: once total intake was accounted for, eating protein right around workouts made no significant difference. Spreading intake into about 20 g every 3 hours beat smaller frequent or larger infrequent doses for muscle protein synthesis over 12 hours, and 30–40 g casein before sleep raises overnight synthesis.[3][20][21]
Typically 70–80% protein in sports products; fast-digesting and high in leucine.[3]
Typically 70–80% protein in sports products; fast-digesting and high in leucine.[3]
Over 90% protein, with less lactose and fat; same proteins as concentrate.[3]
One 12-week RCT (by the manufacturer) found muscle-thickness gains similar to whey.[19]
Plant protein overall gave slightly less muscle than animal protein (SMD −0.20); non-soy plant data rest on only 5 RCTs.[18]
Adding carbohydrate after training did not increase muscle protein synthesis beyond adequate protein alone; carbohydrate mainly helps glycogen recovery.[3]
One 10-week trial in older men found extra lean mass and bench-press gains from creatine plus whey, but other studies found no added benefit.[23]
Protein leaches calcium and weakens bones
A meta-analysis found no adverse effect of higher protein on bone and a small benefit for lumbar-spine density (+0.52%).[25]
Look for a simple whey (or soy/pea) powder that gives 20-40 g protein per serving with few added ingredients, ideally with a certifier-listed batch; it only helps if you are short of your 1.4-2.0 g/kg daily protein.
One scoop gives 24 g, inside the researched 20-40 g range, and the India version has been on Informed Choice since 2014, with batches tested across flavours including Alphonso Mango.
Watch out: Flavoured versions add sweeteners. Check your batch on the certifier page.
An unflavoured whey with about 25 g protein per serving, Informed Choice-listed (unflavoured batches included), and sold by HealthKart's own company, Bright Lifecare.
Watch out: The added enzyme blend has no support in the Proven Stack research. Treat it as ordinary whey. Flavoured versions (e.g. B091HTLXL3, Rich Chocolate, ₹4,198) are also on the certified list.
A vegan powder at 26 g per serving, Informed Choice-listed (Rich Chocolate batches tested), and sold by Fast&Up itself.
Watch out: It's pea/rice, not soy. In Reid-McCann 2025, non-soy plant proteins gave slightly less muscle than milk protein, so lean towards the top of the dose range. Flavoured, with added sweetener.
