The Claim
Ingestion of a soy-dairy protein blend or whey protein after resistance exercise similarly increases mRNA expression of SLC7A5, SLC3A2, SLC38A2, SLC36A1, and SLC7A1 in human skeletal muscle.
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.
After resistance exercise, consuming either a soy-dairy protein blend or whey protein results in the same increase in the activity of five specific genes involved in amino acid transport in human muscle cells.
See the scientific wording
Ingestion of either a soy-dairy protein blend or whey protein after resistance exercise similarly increases mRNA expression of five key amino acid transporters (SLC7A5, SLC3A2, SLC38A2, SLC36A1, SLC7A1) in human skeletal muscle, indicating that both protein sources activate the molecular machinery for amino acid uptake to a comparable extent.
After exercise, when protein is eaten, amino acids enter the bloodstream and signal muscle cells to turn on genes that make proteins responsible for pulling more amino acids inside. This happens with both soy-dairy and whey protein, so both types of protein make the muscle ready to absorb amino acids just as much, even though one keeps amino acids in the blood longer.
What the research says
1 studyAfter working out, both soy-dairy protein and whey protein turned on the same genes in your muscles that help bring in amino acids — they worked just as well for this part, even though the soy-dairy blend kept amino acids in your muscles a little longer.
