Vitamin E is stable at room temperature. It doesn’t need to be refrigerated. It isn’t destroyed by cooking. It stays active in foods that have been frozen.
Vitamin E is also stable in light and in the presence of acid and alkali. It occurs as a thick, yellowish oil.
You may need more vitamin E if you have a malabsorption syndrome in which steatorrhea (excess fat in the stool) occurs. These include lactose intolerance, tropical and non-tropical sprue, celiac disease, cystic fibrosis, and ulcerative colitis. They can also include pancreatitis and issues that lead to surgical removal of all or part of the pancreas (pancreatectomy).
People need more vitamin E if they are over 55 years of age. You also need more if you consume moderate to heavy amounts of alcohol, have chronic alcoholism, or have liver diseases, such as cirrhosis.
Women who are pregnant or breastfeeding may need to take supplements, but you should talk to your healthcare provider before doing so.
Symptoms of vitamin E deficiency in newborns include hemolytic anemia, disease of the retina (retinopathy), and swelling. Low vitamin E levels in adults have been linked with an increased risk for hardening of the arteries (atherosclerosis), cancer, and cataracts.
Vitamin E is a relatively safe vitamin. Vitamin E is fat soluble and can build up in the tissues of the body. But hypervitaminosis is rare. Symptoms of too much vitamin E include fatigue, weakness, nausea, blurred vision, flatulence, and diarrhea.

Vitamin E can increase the effects of oral blood-thinning medicines (anticoagulants). This may cause an increased clotting time and bleeding.
