Can this be the cause of IBS? I also quit diary products to get rid of gas, but I still get it like today (cause i ate beans)...so should I eat it again? I'm thinking about taking these vitamins to control my hperthyroidism -

Multivitamin, with minerals, as recommended on the label
Evening primrose oil, two 500 mg tablets three times daily
Vitamin C, with bioflavonoids, 1,000 mg
Vitamin B complex, 50 mg twice daily
PABA, 3,000-5,000 mg

Thanks
