It seems not enough to be known that blood pressure medicines especially the ACE blockers can cause a lack of zinc and that supplementation may be needed.

Thanks to the Corona most people have been taking zinc during this period.

Some 20-25 mg per day may be enough.

If high doses of vitamin C are taken as well then also a copper deficiency can show up [A low dose of zinc alone will not cause a copper deficiency, a high dose can cause problems]

Zinc and copper are best not to be taken at the same time.

As interactions of various supplements is not an easy subject you better ask for advice if you take them on a long term basis or do your own homework with Google.
