The Claim
A 35-gram dose of hydrolyzed whey protein containing 3.8 grams of leucine enhances muscle protein synthesis and supports gains in muscle mass and strength in pre-conditioned older women during resistance training.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Consuming 35 grams of hydrolyzed whey protein with 3.8 grams of leucine increases muscle protein synthesis and leads to greater gains in muscle mass and strength in older women who are already engaged in resistance training.
See the scientific wording
A 35-gram dose of hydrolyzed whey protein containing 3.8 grams of leucine provides sufficient amino acid stimulation to enhance muscle protein synthesis and support gains in muscle mass and strength in pre-conditioned older women during resistance training.
When a person drinks a protein shake with enough leucine, the leucine enters the bloodstream and signals muscle cells to start building new proteins. This signal turns on a key molecular switch called mTORC1, which tells the cell's protein-making machinery to work faster. When this happens right after lifting weights, the muscle uses the new proteins to grow bigger and stronger.
What the research says
1 studyOlder women who drank a 35g whey protein shake around their workouts gained more muscle, got stronger, and walked faster than those who didn't — proving the shake helped.
