You have to see this product to believe it, some call it a breakthrough in fungi development...not sure if we would agree with that, but we think we have a pretty good product here.

24K Gold added to this product

Although, as far are we know, there is no proven study that has determined pure gold helps to promote fungi growth.... we have done our own studies and have concluded that in side-by-side tests, over 6 months, it does. We add 24K gold flakes to certain products we sell, so if you see little gold flakes or nuggets in your product, this is NOT contamination. 24K gold is non-toxic and edible.
