When me and my siblings were children, our mother was always after us with raw fruits or bowls of fruits chaat. She always emphasized on taking a good diet that included a lot of veggies and fruits. Well, at that time we usually ran away from the ‘good diet’, but then it is her persistence that led us into becoming healthy adults. She was, of course, right. A healthy diet containing vegetables and fruits is essential especially in this fast paced modern era as they contain various vitamins and minerals essential for normal body functions and growth and development.
One of the fat-soluble Vitamins, Vitamin E is essential in building up a strong immunity and keeping eyes and skin healthy. In fact, recently, Vitamin E supplements are being marketed as antioxidants providing protection to the body cells from the damage from free radicals. Let’s take deeper dive into the knowhows about this vitamin.
What are the problems related to Vitamin E deficiency?
Earlier vitamin E deficiency was thought to be very rare and, when it did occur, it was usually not associated with a poor diet. Howbeit, clinicians in current era believe that people are not obtaining enough vitamin E from their diet alone, especially now that everyone is migrating towards fat-free or low-fat diet.
The fact is that vitamin E deficiency is a chiefly a result of malfunction of nutrient absorption. Premature birth is also a risk factor for vitamin E deficiency particularly if the weight is less than 3.5 pounds. A good paediatrician can, however, take care of the problem by spotting and treating it early. In individuals with fat absorption problems like in inflammatory bowel disease also are at risk of vitamin E deficiency.
Also, people having an issue of low dietary fat levels are at risk of vitamin E deficiency, since the vitamin is fat-soluble and requires fat for absorption. Individuals with cystic fibrosis, gastric bypass surgery, or those with malabsorption conditions like Crohn’s disease, pancreatic insufficiency, or liver disease. Thus, it becomes important to supplement Vitamin E, especially in people taking low-fat diet. Supplements are available in various forms like Evion capsules.

Nonetheless, studies have shown that vitamin E supplements does help in those who are suffering from Vitamin E deficiency, however rare they might be.

Liver synthesizes several types of cholesterols including HDL, LDL, and VLDL, required for many functions of the cells, hormones and nerves. Naturally, their levels are maintained as required for proper functioning. However, improper diet and altered lifestyle may imbalance the cholesterol levels, leaving cholesterols in oxidized state which can be harmful. Studies have established that antioxidant action of vitamin E provides protection against oxidization of cholesterols by fighting off free radicals.
Tocotrienol isomer of vitamin E is particularly helpful as it reduces activity of HMG-CoA reductase, an enzyme required in cholesterol synthesis. It also reduces cell adhesion, thus, hindering the progression of atherosclerosis. Natural Vitamin E, however, is more beneficial than artificial one.
2. Antioxidant action and slowing disease progression
Free radicals are responsible for damaging various cells in our body, leading to development of many health issues including heart diseases and cancer. The antioxidant action of certain isomers of Vitamin E are helpful in fighting these free radicals, thus preventing the damage and fighting inflammation. This action is helpful in naturally slowing down aging of cells and preventing health conditions like heart diseases.
Studies have shown that vitamin E improves immunity, thereby preventing common health issues and some serious illnesses as well. Researches have shown that antioxidant and immune-enhancement actions are particularly seen in isomers alpha-tocotrienol and gamma-tocotrienol. Delta-tocotrienol also shows mild action.
3. Skin protection and repair
Vitamin E helps skin by fortifying the capillary walls, improving skin moisture and elasticity. Vitamin E acts as a natural anti-aging nutrient.

8. Helpful in Alzheimer’s disease
Studies has shown that tocotrienols are helpful in protecting against Alzheimer’s disease due to their anti-inflammatory action. Vitamin E slow down the progression of memory loss and functional impairment in individuals with moderately severe Alzheimer’s disease and other neurodegenerative conditions. Vitamin E taken along with vitamin C is helpful in reducing the risk of developing various kinds of dementia.
9. Lowering cancer risk and side-effects of treatments
Isomers of vitamin E are helpful in protecting against cancer. Animal studies have shown that oral intake of tocotrienols is effective in supressing tumour growth. Although, a clear mechanism is yet to be established, various mechanism can possibly be behind the benefits like supressing genes related to cancer, inducing cancer cell death, constraining angiogenesis and supressing growth of blood vessels within the tumour. Vitamin E is found useful in cancers of breast, hepatic, prostate and skin in animal models.
Vitamin E is also helpful in reducing the side-effects of various treatment methods like radiation therapy or dialysis. The protective effect is due to the antioxidant action fighting off the free radicals. Vitamin E is effective again other medicinal drugs’ side effects like hair loss or damage to the lungs.

What are the risk associated with Vitamin E supplements?
There is still not enough evidence regarding effects of vitamin E; benefits or risks. However, long term use of vitamin E has been found to increase the risk of stroke. In fact, clinical research has found that patients taking either natural vitamin E or synthetic in dosages over 400 IU/day were at a greater risk of death from varying causes. Some studies hint that diabetics or patients suffering from cardiovascular conditions are at higher risk of heart failure if they take natural vitamin E at or above 400 IU/day.
Also, vitamin E may be harmful if consumed during early pregnancy. A study found that pregnant females taking vitamin E supplements within the first 8 weeks had a 1.7 – 9 times greater risk of congenital heart defects.
Another study with large population established that males taking multivitamins over 7 times a week along with additional vitamin E supplements were at significantly higher risk of prostate cancer.
