More and more Israelis seem to choose the vegan way[Tzimchonut] or alternatively also the vegetarian way [tivonut]
Those who are VEGAN should for sure take extra vitamin B 12 [best sublingual in the form of methyl-cobalamin].
Other supplements that may be imprtant are Taurine, likrly also vitamin K2 and Omega D3 [DHA] and possibly also carnosine..
Ask you physician for advice, if this is also the area he deals with.

May we all stay healthy!
