Vegetarians show creatine stores in muscle roughly 20-30% lower than meat-eaters, and supplementation closes that gap faster in them than in anyone else studied
Long-term vegetarians carry muscle creatine stores 20 to 30 percent below meat-eaters, and when both groups supplement at the same 5-gram dose, the vegetarian response is faster, larger, and more measurable across strength, sprint power, and cognitive tests.
