Vitamin E

Vitamin E protects cells against oxidative stress, which can damage cell membranes and increase the risk of certain diseases. It can also help improve the immune system, prevent blood clots, and support heart health.

The recommended daily intake of vitamin E varies depending on age and gender.

Men: 15-20 mg/day
Women: 15-20 mg/day

People who are at greater risk of vitamin E deficiency include:

People on a low-fat diet
People who have trouble absorbing fat, such as people with cystic fibrosis or Crohn's disease.

However, it takes a long time for the body to reach a state of deficiency. It is estimated that it takes decades to deplete the body of vitamin E (NNR, 2012).

Symptoms of vitamin E deficiency can include:

Reduced immune function
Muscle weakness
Vision problems
Increased risk of heart disease.
