Higher dairy protein intake doesn't just correlate with elevated IGF-1—it appears to actively drive it through two distinct pathways. Essential amino acids in dairy may either up-regulate IGF-1 gene expression directly, or reduce the clearance of IGF-1 from circulation. This reframes dairy from a passive macronutrient into a signaling input that modulates growth-factor biology at the transcriptional level.
