Do you need a boron supplement?

Boron is a trace element in food, but it is not established as essential for humans. There is no recommended daily intake in Germany or from EFSA. 1

Why do researchers study it?

Human research has explored cognition, hormones, bones and joint discomfort. These studies ask different questions: a change in a test score or blood marker does not by itself establish a lasting health benefit. 2 3 4 5
