Sounds so simple.... But how can one check vitamin D iu's for oneself? What machine is used, and how does it work?
Or is this a public relations piece from the mushroom marketing board?

- verisimi 3y agoThanks. If that's it, it doesn't sound that amazing or accurate: > A nonspecific test merely indicates that any of several in a category of substances is present. Although a nonspecific test could statistically suggest the identity of the substance, this could lead to false positive identification. However, the high temperatures (300°C) used in the GC-MS injection port (and oven) can result in thermal degradation of injected molecules,[3] thus resulting in the measurement of degradation products instead of the actual molecule(s) of interest. from the wiki
