- Supplemental protein from whey and pea increased integrated myofibrillar protein synthesis (MPS) rates to 1.59 ± 0.11 %/d and 1.59 ± 0.14 %/d respectively, compared to the RDA of 1.46 ± 0.09 %/d for whey and 1.46 ± 0.10 %/d for pea.Strong
- Supplemental protein improved anabolic signaling and integrated MPS in older males.Strong

- 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
