Be careful what you put in your mouth; It may blow up in your face:
At the 1936 meeting of the American Chemical Society, professor Edward Bartow of the University of Iowa presented a commercially viable means of extracting large amounts of inositol from waste corn. As a possible use for the chemical, he suggested inositol nitrate as a more stable alternative to nitroglycerin. Today, inositol nitrate is used to gelatinize nitrocellulose, and thus can be found in many modern explosives and solid rocket propellants.
Ever heard the song
"Fly me to the moon"?
Other uses include:
"Inositol has been used as an adulterant (or cutting agent) in many illegal drugs, such as cocaine, methamphetamine, and sometimes heroin. It is presumed that this use is connected with one or more of the substance's properties of solubility, powdery texture, or reduced sweetness (50%) as compared with more common sugars."
The source for these extracts was linked in my earlier message.
I am not sure of the intent of this post but you are comparing apples to oranges. Here is a list from the Wikipedia article you are quoting of the the different forms of inositol:
allo-Inositol
cis-Inositol
D-chiro-Inositol
epi-Inositol
L-chiro-Inositol
muco-Inositol
neo-Inositol
scyllo-Inositol
Inositol 1-methyltransferase
Inositol 3-methyltransferase
Inositol 4-methyltransferase
Inositol nicotinate
Inositol phosphate
Inositol trisphosphate
Inositol pentakisphosphate
Inositol hexaphosphate
Inositol triphosphate receptor
Inositol hexanicotinate
This is a description of the vitamin inositol:
Inositol is a water-soluble member of the B complex vitamins and is also known as lipotropic factor.
This vitamin is found in both plant and animal tissues and in cereals it is present as phytic acid.
Insositol is phosphorus based.
The body?s intestinal bacteria are able to produce inositol from glucose, however some of this vitamin may be lost into cooking water.
There are no known toxic effects to this vitamin...
There many forms of inositol just like there are many forms of water, fresh water, salt water, heavy water, polluted water, etc. However fresh water is the only form of water one would actually ingest.
Bottom line is I have been taking inositol for my hair for over 40 years and my hair looks good and I am in great health.
