Yes, I forgot about the ADD / ADHD boys I worked with. From your post;

"Continuing the quote on boron from Minerals for the Genetic Code : "Boron is known as the calcium helper and for the metabolism of calcium, magnesium and phosphorus. Boron improves retention of both calcium and magnesium and elevates circulation of serum concentrations of testosterone.
Boron works in the body toward brain function, activates vitamin D, promotes electrical brain activity, enhances memory, and promotes alertness. Signs of possible deficiency include ADD/ADHD, osteoporosis, arthritis, fatigue, decreased motor function, decreased short-term memory, decreased brain function, and increased loss of calcium and magnesium in the urine."

By observing, monitoring symptoms, then adjust accordingly.
This goes for any supplement, or even diet.

When one of my boys starts to get up at nights again, to pee, I know he needs more boron. This happens when he has not taken it for 2-4 weeks; no, it is not possible to cover with diet. (My son had terrible problems with frequent urination from he was little, 10 years of urinating up to 15-20 times a day was cured within days of borax supplement)

- To prevent this happening; one capsule or two weekly is what is needed. In mg that would be 450 mg of borax, once or twice weekly.
This is approx the maintenance dosage for me too.
450 mg x 2 = 900 mg = 11% boron = 99 mg boron: 7 days = 14 mg boron daily. Some weeks half of this.

My other son also had great benefits of it, he is very active, take diving lessons. Had cramping muscles, often.
He needs it to be able to stretch out properly in positions before the dives. Magnesium needed too!
Also sometimes when the chlorinated water itch to much he ask for the soothing effect of borax water; one drop or two in his eyes.


"Benefits:

o Prevents arthritis: Boron is a successful treatment option for Arthritis and in more than 95% of cases significant improvement was noticed by bringing about effective calcium integration into the cartilage and bone. With increase in age the bones might become weak and porous and boron can stem this deterioration effectively.
o Reduces severity of Rheumatoid Arthritis : Boron greatly reduces the allergic conditions that are typically associated with Rheumatoid Arthritis .
o Used for body building in males: Boron is able to enhance the testosterone levels in males and this quality is increasingly being made use of by male body builders and athletes. Though some weight lifters prefer to take boron supplements as it enhances the testosterone levels, making them sturdy, no concrete evidence is available to drive home this point.
o Helps in bone building: The bone building capacities of boron are often ignored in favor of calcium. However, it is boron that works in unison with calcium to strengthen the bones. It plays a very important role in minimizing the risks of osteoporosis and arthritis. Boron helps in the metabolism of minerals that are involved in bone development such as calcium, magnesium and copper. Boron also affects the hormones of estrogen and testosterone that are also related to the overall health of the bones.
o Helps in production of estrogen: Boron might improve the production of estrogen in menopausal women, bringing back their sex drive within a few days of treatment. Boron increases the level of natural sex hormones in the body, thereby reducing the need for Hormone replacement therapy.
o Ensures proper embryonic development: Boron is essential in reproduction and development of fetus though not much information is available in this regard.
o Prevents post menopausal osteoporosis: Boron can ease the symptoms such as hot flashes and night sweats that are typically associated with menopause.
o Useful in cancer therapy: Boron neutron capture agents are used for cancer therapy and in the development of strong enzyme inhibitors. Boron compounds are also used as antibody mimics that can easily identify biologically important saccharides.
o Helps to maintain proper cell membrane function: Boron plays an important role in maintaining transmembrane functions and in stabilizing the hormone reception.
o Helps in preventing blood clots: It is believed that boron can influence some of the blood clotting factors in the body. However, mores studies need to be done to authenticate this finding.
o Reduces congestive heart failure conditions: Boron can significantly alleviate the difficulties caused by congestive heart failure conditions.
o Lowers plasma lipid levels: Boron helps to reduce lipid accumulation and enables in the removal of cholesterol.
o Decreases the severity of fungal infections: Boron protects the body from a host of parasitic attacks such as Candida Albicans.
o Improves brain function and cognitive performance: Studies have shown that boron can enhance brain function, eye-hand coordination, short memory and concentration.
o It serves as enzyme inhibitors: Boron might inhibit some enzymes while serving as a cofactor for yet another enzymatic reaction.
