I wrote sickbay about the change in ingredients and this is their response:
Dear Madam,
Thank you for your email. In reference to your question, we spoke to the manufacturer. It appears that the formula was changed which it is something that we weren't aware of; Due to FDA regulation, any products sold in the US cannot contain any animal products. We have updated the current ingredients in our website. We apoligize for any inconveniences.
Sincerely,
Mark Urruela
