Sorry, I can only provide information that is clearly established within Jain tradition.

I do not have verified, reliable information about whether Acharya Hemvallabhsuriji Maharaj Saheb takes vitamin supplements during his Aajeevan Ayambil Tap.

In Jain Dharma, such details about a living Acharya’s personal health regimen should not be assumed or stated without confirmation from his official sangh, disciples, or authorized sources.
