Natural Water Containing Vanadium


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.

Krill Omega Red Oil - English version


I've been asked to translate my German blogpost on Krill Omenga Red Oil
I had seen an advertisement in a German magazine called tina "the premium women's magazine" No. 16 of the 10.04.2012 edition, p. 65, concerning Krill Omega Red Oil.

We see Kirsten, a "busy and helpful lady" in retirement. She has dressed up for the poster in the colour of the advertised product. The ad wants to tell us, what "krill Omega unlike fish oil" can do. In the first paragraph after under the title "I look after my heart" but no difference to fish oil is presented. Then addressed as"the secret of krill Omega", the krill capsules are described as odor-free - same applies to the salmon oil capsules from ALDI, Lidl & Co.[German discounter chains]. Secondly, it is claimed that krill is a more effective source of than omega-3 fatty acids than fish oil . "1 Capsule contains: 200 mg phospholipids, of which 60% are omega-3 phospholipids." 115 mg omega-3 fatty acids with the following composition: 50% EPA, 28% DHA and 22% other fatty acids. "Antioxidant: astaxanthin 25 µg." The ALDI (South) salmon oil capsule contains 191 mg omega-3 fatty acids, of which 148 mg are DHA and EPA (in a capsule of krill Omega there are only 90 mg). Well, there's something fishy! Moreover it's advertised, that krill oil comes from the most unpolluted sea - this may be true, but also the fish oil capsules are free of pollutants. Whether krill oil or fish oil can maintain heart health, is still under discussion. There is not a single study that describes an advantage of krill oil.

Let's have a look at costs. Most sites on the Internet charge about €27 for 60 pills [German sources]. At ALDI, you pay approx. 5 ct (approximately €3.00 for 120 capsules) per gram of fish oil. For Krill Omega Red Oil you'd pay a whopping €2.50 per gram of krill oil.

Krill Oil is a by-product of the extraction of krill powder for animal fodder.
