bo·ron (B),

(bōr'on),

boron

A trivalent nonmetallic element, (atomic number 5; atomic weight 10.81).
 
Alternative medicine
Boron is believed by alternative health workers to be useful in pregnancy and menopause as it increases oestrogens; they also believe in boron deficiency.

Boron-rich foods
Almonds, beans, honey, lentils, peas, peaches, pears and raisins.
 
Molecular biology
A mutation of SLC4A11, which encodes a transporter that regulates intracellular boron levels, results in congenital endothelial dystrophy type 2, a rare form of corneal dystrophy.
 
Nutrition
Boron is non-toxic to humans; while boron is needed for certain cellular activities, a boron deficiency state is not known to exist.

Physics
Boron is used in physics as a neutron-absorber.
 
Physiology
Boron is a trace mineral needed for proper absorption and utilisation of calcium to maintain bone density, and may help prevent postmenopausal osteoporosis; daily supplements of boron may help retain dietary calcium, magnesium and phosphorus, and increase production of oestrogen and testosterone. It is also thought to safely promote muscle growth by body-builders.
