About Boron
Boron citrate is a bioavailable form of boron used as a dietary supplement. It's often promoted for bone health, joint health, and hormonal balance, but the evidence supporting these claims varies. While generally considered safe at recommended dosages, high doses may lead to gastrointestinal issues and other side effects. More research is needed to fully understand the effects and optimal dosages of boron citrate.
