The list of ingredients is NOT AVAILABLE.
In a world where you can't for years buy a food item without a painstaking list of ingredients, warnings that this product may contain nuts, has been prepared in a factory that processes nuts, etc etc etc, we are living in an altered reality where we are OBLIGED to take a substance directly into our bodies with NOTHING ON THE LABEL TO SAY WHATS IN IT.
Informed consent hey ?
[Sorry OP obviously not of the PV party but frankly they are on a hiding to nothing with your question.]
