Acidity

Detailed Answer:
Hello

Thanks for the query

All the supplements you are on are acidic in nature hence they can cause gastirits. Please take these supplements after food or with juice.
I must warn you that potassium supplementation is only recommended for people with potassium deficiency, ig potassium is over corrected you stand a high risk of cardiac arrhythmia.

To overcome the current situation I suggest that you take Tab omperazole once daily before food for 5 days.
Avoid smoking, caffeine and alcohol
Avoid spicy food, make sure your food is bland
Avoid milk and milk products until you are better

I hope I was of help, if you have any further queries please get back to me

Regards
