Q: How much Boron is safe to take per day?

A: From the Health Canada statement on Boron use, it appears that individuals living in locations with Boron concentrations up to 29 mg/L show no deleterious effects. Aside from that, Health Canada has a “chronic reference dose” for multivitamins (0.7 mg/day) and a maximum chronic dose for bone mineralization (osteoporosis) of 3.36 mg/day. Boron has also been used in the long term treatment of epilepsy, at dosages far higher than 3 mg/day. Basically, long term use of boron at low amounts should be perfectly healthy.
