The Claim
Short-term creatine monohydrate supplementation (20 g/day for 3 days followed by 5 g/day for 7 days) causes upregulation of mRNA and protein content of key signaling kinases—p38 MAPK, ERK6, and PKBα/Akt1—in skeletal muscle tissue of healthy young men, with fold increases ranging from 1.3 to 5.0, indicating activation of cell signaling pathways associated with muscle growth and metabolism.
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.
Taking creatine for just a week can turn on important muscle cell signals that help with growth and energy use in young, healthy guys.
See the scientific wording
Short-term creatine monohydrate supplementation (20 g/day × 3 days, then 5 g/day × 7 days) causes upregulation of mRNA and protein content of key signaling kinases in skeletal muscle of healthy young men, including p38 MAPK, ERK6, and PKBα/Akt1, with fold increases ranging from 1.3 to 5.0, indicating activation of cell signaling pathways linked to growth and metabolism.
What the research says
1 studyThe study gave young men the same creatine dose described in the claim and found that it turned on genes and proteins in muscles that help with growth and energy use.
