I myself run marathon races have been run as the Brocken Marathon and had since I take these capsules, no more problems. Noh years ago 2.5 plagued me knees (runner's knee) and I had just always somewhere overloading in the tendons. Come just come from our food degenerated nowadays ... the supplementation Horsetail is simply very useful.
In this package is twice as many capsules as in the overpriced variant of Ultra Sports Ultra Sports but almost as expensive! Comparing the capsules and opens it, there is the identical material. I can only advise against any of these over-priced company and give an indication of deutilchen Vita Ideal!
