Vitamin C and vitamin B-12
Another unfortunate combination is vitamin C and vitamin B-12. Dobrynina recommends the doses of vitamin C and vitamin B12 to be taken at least two hours apart.
Also, Mayo Clinic explains that combining these two supplements can lower levels of vitamin B-12 in the body; and you don’t want a B-12 deficiency as it can lead to anemia, lower levels of healthy blood cells, causing a general state of fatigue, memory issues and even problems with mobility and balance.

Vitamin E and vitamin K
Taking vitamin E and vitamin K together is also not the best idea due to their opposing effects on coagulation. According to various studies, vitamin E supplements can cause excessive bleeding in some individuals. To counteract such action, doctors recommend vitamin K. But taking them together annihilates the effect of vitamin K.
In a 2023 case study detailed in the Journal of Medical Case Reports, excessive supplementing of vitamin E can prevent vitamin K-derived coagulation factor synthesis. This can lead to serious bleeding incidents among which gastrointestinal bleeding and intracranial hemorrhage.
According to this article taking Zinc and Copper together is not good?
This is Not true, for zinc to be sufficiently absorbed some copper is needed in the right proportions.
For example my bottle of zinc has this mixture:
15 mg of zinc AND 2 mg of copper per capsule.
A lot of these combos come in a Multiple vitamin…. Are you suggesting that I STOP taking my Multiple Vitamin???
