Can zinc INCREASE stomach acid?

A family member is having digestive issues, all pointing to low stomach acid. I proposed that hydrochloric acid is worth a spot, but they are fearful of it and want to go the natural route. This person is a vegetarian and I'm pretty sure they are deficient in zinc and I read that a zinc enzyme is necessary to produce stomach acid. The problem is all the studies I've been reading on it indicate the OPPOSITE, with increased stomach acid in zinc deficiency and an inhibition of stomach acid when supplementing with it. I've been searching Scholar and Pubmed until I was blue in the face and I've found nothing to indicate that zinc deficiency causes low stomach acid and supplementing will help that outside of non-peer reviewed blogs. Has anybody increased stomach acid with zinc? At this point I am afraid to recommend it because Idk if it would help them or hurt them.

Thanks :)

Zinc is one of the minerals required to produce HCL, so a defficiency in zinc will lower HCL production.?? The other part of this is that zinc will help kill off H. Pylorii, and an H. Pylorii infection will lower HCL production:



Zinc-Carnosine. Zinc is a micronutrient mineral that has multiple functions in human biology, chiefly acting as a coenzyme in many enzyme systems that defend against free radical damage (Gotz 1996; Gotz 1997; Langmead 2001; Noguchi 2002). Recognizing that H. pylori infection causes increased oxidative stress, a group of Ecuadorian scientists investigated whether zinc deficiency might cause increased inflammation in the stomachs of people infected with the organism (Sempertegui 2007). They studied 352 patients with dyspepsia (stomach pain and dysfunction) who had biopsy samples taken during endoscopy. Patients with H. pylori infections had significantly lower zinc concentrations in their tissue samples than uninfected patients. Indeed, the more severe the inflammation, the lower the zinc levels in the infected subjects (Sempertegui 2007). These results and others have led some researchers to consider zinc to be a ???gastric cytoprotective??? (cell-saving) nutrient (D???Souza 1991).
