Whey protein shows greater rates of MPS compared to soy protein at equivalent doses.
Whey protein may be a better choice for promoting muscle protein synthesis in elderly individuals compared to soy.
StrongSupportsmedium confidence
The greater rates of MPS observed with equivalent doses of whey as compared to soy protein suggest that protein source is an important factor in reaching and surpassing the anabolic threshold.
Why this rating
The study design is robust as indicated in the abstract.

- Ingestion of 20 g and 40 g of soy protein isolate does not stimulate increased rates of myofibrillar protein synthesis (MPS) under resting conditions in the elderly.Strong
- The differences in MPS rates between whey and soy protein may be due to higher leucine content and more rapid leucinemia with whey.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
