can vitamins go rancid
A. Vitamin E should be nearly odorless. If your soft gels smell bad, the vitamin E in them may have gone rancid. It's never a smart idea to consume rancid oil, since this increases your body's need for antioxidant protection. That's why most people take vitamin E in the first place. It isn't necessary to store vitamin E in the refrigerator, but some forms are more vulnerable to oxidation (spoiling).
