Whey protein supplementation significantly improved bench press performance by a mean difference of 8.87 (95% CI: 5.95-11.79) and squat performance by a mean difference of 9.60 (95% CI: 5.61-13.60).
Practitioners can recommend whey protein to enhance strength performance in young adults engaged in resistance training.

- Athletes aiming to reduce fat mass and preserve FFM should consume protein intakes in the range of ∼1.8-2.7 g kg(-1) d(-1).Strong
- A minimum daily protein intake of ≥1.6 g/kg is necessary to observe significant improvements in muscle mass from whey protein supplementation.Strong
- Most athletes ideally need 1.2 to 2.0 grams/kg of body weight/day of protein, preferably split across 3-4 meals.Strong
