Is vanadium
water going to be hype soon?
Vanadium is
a metal, that oxidates quickly and it’s used as an alloy with steel. Vanadium
pentoxide is used as a catalyst for the production of sulfuric acid [1]. Only metallic
vanadium is rare in nature. Vanadium compounds occur in quite a lot of
different minerals. Vanadium is nearly as common as copper or zinc.
Seawater has
a high concentration of vanadium. Water from springs around Mount Fuji contains
as much as 54 μg per liter. Amanita muscaria, AKA fly amanita, contains
amavadin of which the biological function is still unknown, but maybe it serves
as a toxin for protection of the mushroom [2].
It is still
not known, if vanadium is essential human nutrition. “The Tolerable Upper
Intake Level (UL) of dietary vanadium, beyond which adverse effects may occur,
is set at 1.8 mg/day.”
There had
been a study on Mount Fuji water and the effects on diabetes mellitus [3]. “In
the clinical studies, the levels of blood glucose and serum HbA1C of
hyperglycemic patients were significantly reduced by three month consecutive
treatment of this Mt. Fuji ground water”, but the effect was only seen in
patients, who believed in the effect. The study has been publishe in Japanese.
I haven’t seen any notion on how many humans were on the study. Also the study
mixes date obtained from a study on mice with a study on humans. The authors
concluded: “Thus both animal and human studies suggest that the daily treatment
with Mt. Fuji ground water containing natural vanadium is useful for the
regulation of blood glucose levels and the improvement of QOL to the hyperglycemia
patients due to the improvements of glucose transporter and the insulin
receptor and so on. However it might be little difficult to expect the
significant improvement of the severe conditions of diabetes mellitus by the
consecutive treatment of natural vanadium water, since this ground water is
good as a supplement.” I’m not quite sure what the authors want to tell us.
I’ve also
seen a review article [4]: “A systematic review of vanadium oral supplements
for glycaemic control in type 2 diabetes mellitus”. “The authors concluded that
there was no good evidence that oral vanadium supplementation improved
glycaemic control in diabetes and so the routine use of vanadium could not be
recommended; … .”
I don’t know
if there’s going to be a hype on vanadium water, but as to a scientific basis –
I’ve found none. But that won’t keep people from telling you, that you need an expensive
dietary supplement.
