Taking L-arginine or L-arginine plus sodium butyrate didn’t change blood sugar levels after eating in obese people — even though it raised one appetite hormone.
Scientific Claim
In non-diabetic adults with obesity, neither oral L-arginine alone nor in combination with sodium butyrate significantly alters postprandial blood glucose levels compared to no supplement.
Original Statement
“No significant differences in glucose levels were observed between interventions.”

Assessment Explanation
The claim correctly reflects the absence of statistical difference in glucose levels. No causal language is used, and the wording matches the data.
Evidence from Studies
Supporting (1)
The effect of oral l-arginine alone or in combination with sodium butyrate on glucagon-like peptide-1 secretion in non-diabetic adults with obesity.
The study gave people with obesity either L-arginine, L-arginine plus sodium butyrate, or nothing, then checked their blood sugar after eating. In all cases, their blood sugar stayed about the same—so the supplements didn’t change it.
