I do appreciate being careful but in Boron studies we are talking aboit active Boron.
Dr.Reza Naghii who ran studies on Boron decades said it does not matter where it comes from (Boron Citrate, sodium tetraborate decahydrate etc) as long as we know the % of active Boron.
Example a study on Boron and Osteoarthritis they used 55mg Sodium tetraborate decahydrate (6mg active/elemental Boron).
In another Boron study they used 102.6mg sodium tetraborate decahydrate (11,4 active/elemental Boron).
As you can see , in Sodium Tetraborate Decahydrate, its about 11% active Boron.
Boron CItrate is Boron with Citric Acid. So taking 200mg Boron Citrate (5% Active Boron) is 10mg Boron (the dose Dr Naghii used in some of his studies where we saw testosterone increasing effect) and rest is Citric Acid.
The study you are showing where Dr.Naghii was involved, they used 10mg of Boron from sodium tetraborate.
From the study:
The boron supplements were pre-
pared from sodium tetraborate - containing 10 mg of boron.
From the email I got from Dr.Naghii/some.of his words: (to prove it completely):
"The boron content of Borax (Sodium tetraborate decahydrate) is 11.3 per cent." (I said about 11% which is correct)
" 25–30 mg of borax provides about 3 mg of boron. As used in postmenopausal women study" (as an example).
So like I said, we need to look for % /mg of active Boron. To get 10mg active Boron like they used in one of the studies, we need 100+mg Burax (Sodium tetraborate decahydrate or 200mg Boron Citrate where 5% of it is Active Boron).
