Royal Jelly
The final active ingredient listed in Metabolife is Royal Jelly. Similar to the bee pollen, royal jelly is "a secretion of honey bees." It is used as a health tonic, even though "its beneficial effect for man is unproven and...some serious adverse reactions have resulted following its ingestion" (Thien et al., 1996). These effects include asthma, anaphylaxis, and even death (Thien et al., 1996). The goal behind the Thien's study was to find the association between "asthma and anaphylaxis induced by royal jelly." The results of the study indicated that "subjects who experienced an allergic reaction to royal jelly have serum IgE antibodies to a number of royal jelly protein components." However, and additional discovery uncovered that "the occurrence of IgE antibodies that react with royal jelly protein is not confined to subjects known to be allergic to the extract" (Thien et al., 1996). Individuals with other known allergies tended to exhibit the same symptoms, in this case. The repercussions of these allergic reactions can be fatal, and yet there is no mention of them on the Metabolife packaging or even on the websites where it is advertized. Again, this is an indication of lack of safety of the substance. An individual with severe allergies could put himself in great jeopardy by consuming the Metabolife product.
