Hey has anyone ever gotten a sick stomach after taking vitamin c? I bought some generic chewables this morning and took 2 (1000 mg). NOw i have this bad belly ache and i cant attribute it to anything else. I ususally take the GNC brand with no problems like 1000mg in the morning and sometimes another 1000mg at night. I have never had any problem such as this. I did notice that the generic stuff i took this morning did not taste good to me at all. In fact i was like oh thats nasty.
