Did Charles hakala test with boron, or borax? I read somewhere that the correct form of boron is in borax as ionic boron, and that chelates boron is bound too tightly to be separated and will not bind with fluoride. I've also read that the borax is converted to boric acid by stomach acid and that boric acid bonds with fluorine to form fluoborate. I read that on earth clinic. I would also really like to know if borax really works I wish someone would analyze urine after ingestion to check for boron fluoride compounds

Two confirmations now via mass spectrometer that boron is not removing fluoride.

The math error in the message appears to be that the person who wrote it based the 2.837% calculation on a single boron atom being present in borax, when in actuality there are four boron atoms, as evidenced by the formula. Therefore, the correct percentage is:

(molecular wt of borax is 381, boron is 10.81 so (4 x 10.81)/381= 11.3%

Would you trust any information from Charles Hakala when he can't figure out the concentration of Boron in Borax?

Borax IS 11% Boron. The formula for borax is.
Na2[B4O5(OH)4]·8H2O

There are 4 Boron atoms per molecule. He calculated his value assuming one Boron per molecule.

Anyone following his advice is taking four times the amount. BEWARE. Apparently he has set up a lab measuring levels in bodily fluids.
