I had previously the MSM tablets of Vitabay ([...]), but am now changed to the VegaVital because they are good 4 euro cheaper, for the same quantity and dosage. The VegaVital have against the Vitabay but a very significant drawback for me - they taste very first in your mouth bitter. The Vitabay against loose time was to swallow tablets - a bitter taste because I had never. Quite apart from the product, I have opposed the many to be found on the Internet positive reports may not notice any changes by taking. (But for no devaluation, but purely for the unpleasant taste) hoped I had some relief from my allergies. Why but devalues the tablets because of silica, is beyond me. This substance is one of the most common on this earth (eg taking every child in the sandbox in much higher doses), is generally considered harmless declared in bound form and may therefore at any height (!) Are mixed. The body can not utilize it and separates it easy again. Considered critical, only the nano-form, although not present in tablets.
