This probiotic is sealed in HPMCP (hydroxypropyl methylcellulose Phthalate) which is used to protect enzymes from acid. The European Union banned phthalates in 2003 and all phthalates in toys in 2005. China and Mexico have also prohibited the use of phthalates in toys. So something which is not good to play with how is it that its good to eat. For a probiotic which is so expensive I would not want to be fed plastic along with good bacteria's.
