Dark chocolate contains substantially less polyphenols (reduces iron intake) then say straight cocoa powder, the bio-availability is still affected, however the iron intake is still substantial.

Almost all store bought creatine's are synthetic, as a result are vegan, I recommend going to your local supplement store and clarifying with the staff when purchasing. Most supplement sites should also mention whether their product is vegan or not.

Thank you for taking the time to read and for the feedback :)
