Vitamin Side Effects - Nausea and Cramps

I am wondering if one of the following vitamins could cause stomach cramping and nausea:

Sundown Triple Magnesium Tablet (500mg)
Ester-C 24 Hour Immune Support (500 mg)
B complex,
Gaia Herbs Adrenal Health Liquid Phyto-Capsules
Optimum Nutrition Opti-Women Women's Multivitamin
Vitamin D drops
Sundown Selenium capsules

Thanks!
