A few weeks ago, we had a lady who came in to exchange the chlorophyll she had purchased with one from another brand. Her reason? One of the "other ingredients" included was Polysorbate 80. I overheard her telling the cashier that someone had told her that ingredient caused infertility.
I immediately looked into this because that's what I do. I found the following research:
According to Annals of Allergy, Asthma and Immunology, Volume 95, Number 6, December 2005 , pp. 593-599(7), "it is of current relevance as a 'hidden' inductor of anaphylactoid reactions", and "Polysorbate 80 was identified as the causative agent for the anaphylactoid reaction of nonimmunologic origin in the patient. Conclusions: Polysorbate 80 is a ubiquitously used solubilizing agent that can cause severe nonimmunologic anaphylactoid reactions."
