nausea/headache with supplements

I get nausea and a headache with a familiar confused and dizzy' feeling in my head whenever i take supplements. What could be the causes and possible treatments? I've tried betaine for possible low stomach acid but that gives me burning pain in my stomach.  the nausea and headache begin within 10 minutes of any supplements eg a vitamin pills. I need to take supplements for other health conditions but able not able to tolerate them. Your guidance would be much appreciated.

Raja,

It's not a good idea to take supplements if they make one confused and dizzy.  They are not regulated by the FDA and can have things in them that you don't expect.  These side effects can cause stomach burning and should be avoided
