MIXED — Does Milk Actually Make You Taller?

Analysis summary

Milk supports reaching genetic height potential during growth years but cannot increase height once growth plates have fused in adulthood.

Key findings

• Milk contains Insulin-like Growth Factor 1 (IGF-1) and high-quality protein that are scientifically linked to bone development and linear growth in children.
• Studies show a small correlation between milk intake and height; for example, some research indicates children drinking cow's milk are roughly 0.4 cm to 1.5 cm taller than those who do not.
• Genetics determine 60-80% of a person's final height; milk only helps an individual reach their predetermined genetic potential during their growing years.
• Once growth plates fuse in late adolescence or early adulthood, drinking milk will not increase height regardless of consumption levels.
