Deficiency and toxicity of vitamin E
Vitamin E;
Vitamin E (active from: alpha -tocopherol) is a fat- soluble vitamin with antioxidant properties . It is the one of the body 's primary defenses against the adverse affect of free radicals, thus protecting the biomolecules and cell membranes from destruction.
It also play role in preventing the oxidation of poly-unsaturated fatty acid (PUFA). Moreover, it can reduce the risk of the heart diseases by protecting oxidation of low-density lipoprotein(LDL).the RDA of vitamin E for adults in15mg per day.
Vitamin E deficiency:
The primary deficiency linked with inadequate intake of vitamin E is rare; whoever, other diseases like cystic, fibrosis, attributed to fat malabsorption can lead to vitamin E deficiency.
The common consequence of vitamin E deficiency is erythrocyte hemolysis, which leads to hemolytic anemia(having too few red blood cells)lack of vitamin E can cause oxidation of PUFA in their membranes that result in the breakage of red blood cells (open and spill their contents).
Persistent deficiency of vitamin E cause neuromuscular dysfunctions involving spinal cord and retina of the eye. The loss of muscle coordination, reflexes, and impaired vision are other symptoms of vitamin E deficiency.
Causes:
Vitamin E deficiency is usually caused by a condition that reduces the absorption of dietary fats. These conditions include:
Diseases of the pancreas, liver, or gallbladder
Genetic disorders such as abetalipoproteinemia or familial isolated vitamin E deficiency
Premature, very low birth weight infants (birth weights less than 1500 grams, or 3.5 pounds)
Symptoms:
The primary symptoms of vitamin E deficiency relate to nerve and muscle damage. Symptoms can include:
- Difficulty with coordination and balance (ataxia)
- Muscle weakness
- Vision problems
- Immune system problems
- Numbness and tingling caused by nerve damage
Treatment:
Treatment for vitamin E deficiency typically involves vitamin E supplements under the care of a doctor. The underlying cause of the deficiency also needs to be addressed.
Vitamin E Toxicity:
While vitamin E is considered safe for most people when taken in recommended amounts, high doses can cause serious side effects.
Vitamin E toxicity: Increased supplemental use of vitamin E results in toxicity that is uncommon.
Toxic amount of vitamin E may interfere with vitamin K functioning, thereby hindering the blood clotting action of vitamin K by increasing the effect of drugs, resulting in hemorrhage(a condition characterized by the excessive bleeding). Other symptoms of vitamins E toxicity are listed below:
1) Digestion symptoms: Nausea, stomach cramps.
2) Eye symptoms: Blurred vision.
3) Muscular symptoms: Fatigue
Causes:
The primary cause of vitamin E toxicity is overconsumption of vitamin E supplements. Vitamin E is fat-soluble, which means excess amounts are stored in the body rather than excreted.
Symptoms:

- Nausea
- Diarrhea
- Stomach cramps
- Fatigue
- Weakness
- Headache
- Blurred vision
