If so, why are all the brand providing vitamin B12 supplements? Any suggestions? October 24, 2017 at 6:25 am #17079 BethanyParticipant Dr. Simeons in his book has allowed vitamin C, D, and calcium. So you are safe to take Vit C supplements. BUT BEAR IN MIND that these vits must be taken in non-oily, non-capsule, pill forms with no other extra ingredients listed.
