The Claim
In healthy, resistance-trained young men, daily supplementation with 10 grams of leucine, divided into two 5-gram doses (administered in the morning and post-training), has no effect on the total daily dietary intake of protein or leucine from food sources.
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.
If you're a young guy who lifts weights and you take 10 grams of leucine powder split into two doses a day, it won't make you eat more or less protein or leucine from your regular food.
See the scientific wording
In healthy, resistance-trained young men, 10 g/day of leucine supplementation divided into two 5 g doses (morning and post-training) does not alter dietary protein or leucine intake from food sources during the day.
What the research says
1 studyStudy: Leucine Supplementation Has No Further Effect on Training-induced Muscle Adaptations
The study gave men extra leucine pills but found they didn’t eat more or less protein from food — so the supplements didn’t change their normal eating habits.
