Abstract: Methods for stimulating in-vitro Paecilomyces hepiali or Hirsutella sinensis growth, and nutritional supplement formulations containing such fungal strains are disclosed and described. In some embodiments, such a method may include providing a an effective amount of a P. hepiali fungus strain for use as a stimulating agent on a culture medium for which H. sinensis is grown and regulating the temperature to induce and maintain the growth of the H. sinensis fungus. Alternatively, a P. hepiali fungus may be grown in a similar manner using H. sinensis as the stimulating agent. In some aspects, the growth of one fungus may be sequentially switched with the other in order to improve fungi potency.
