Honolulu, HI, United States, 2006/08/08 - The discussion about the health scare caused by the "Magic-Nano" sealing spray (which, as it turned out, was neither magic nor nano - see this article) has barely ebbed when questions about another nano consumer product arise..
This time, it is not a health scare but rather the opposite – alleged health benefits of nanoparticles.
The German company Neosino AG markets a nutritional supplement, called "Nanosilimagna", containing calcium, silicon, and magnesium, in which the elements concerned are said to be in the form of nanoparticles (3-10 nm), and for which the company claims absorbability superior to that of other physical forms of the same elemental nutrients.
The German weekly newsmagazine Der Spiegel reports in its online edition of August 3, 2006 that two scientific studies it commissioned showed that the Neosino product claims are simply wrong. Not only did they not show superior absorbability, they performed worse with regard to magnesium absorbability than an off-the-shelf product from the supermarket. The super expensive Neosino product costs €49.95 (∼$60) for 45 grams; the supermarket pills were €0.60 for 90 grams!
