Benefits of Vitamin E.

 

Every few years scientists and researchers around the world proclaim a new miracle product. Dis- eases from dry skin to diabetes are prevented or eased and all by a natural substance, with little or no side – effects. Sound too good to be true? Maybe, but in the case of Vitamin E, maybe not.

 

Vitamin E, also known as tocopherol, was first discovered in 1922 and was initially known as the ‘antisterility’ vitamin. Since then it has become widely accepted as an essential vitamin and is used in the treatment and /or prevention of many common ailments.

 

Antioxidant Power.

Vitamin E occurs in nature in eight structurally related forms, 4 tocopherols and 4 tocotrienols, all of which are potent membrane-soluble antioxidants.

In its role as an antioxidant Vitamin E helps to reduce oxidation of lipid membranes and the unsaturated fatty acids as well as preventing the breakdown of other important nutrients by oxygen.

Oxidation is a chemical reaction which involves the addition of oxygen, the removal of hydrogen or the removal of an electron from a substance. The process of oxidation causes the formation of free-radicals, highly unstable molecules which can contribute to tissue and cellular irritation and damage, which can lead to chronic inflammation. A variety of chemical reactions in the body are responsible for the formation of excess free-radicals which is the basis of dis-eases such as heart disease, hypertension and arthritis.Vitamin E has been shown to be effective in protecting the tissues from oxidation and free-radicals and as such, playing an important role in preventing these diseases.

As an antioxidant, Vitamin E also helps to protect the tissues and stabilise the cell membranes of the skin, liver, eyes and breast, as well as protecting the lungs from oxidative damage from environmental substances. The key function of Vitamin E as an antioxidant is to stabilize and modify blood fats so that the heart, blood vessels and in actual fact the entire body, are more protected from injury induced by free-radicals. Another example of this vitamins antioxidant power is in the treatment of leg cramps, studies have suggested that taking 400 IUs daily can be beneficial in treating this condition.

Humans and animals do not synthesize their own Vitamin E so they need to get tocopherols from plants which are the only species capable of synthesizing Vitamin E.

 

Heart Helper.

Vitamin E has been shown to reduce platelet aggregation and platelet adhesiveness to collagen, even more than aspirin.This means that it helps to allow good blood flow and so can decrease the risk of artherosclerosis and cardiovascular disease, particularly in people who are already at risk. This amazing vitamin helps heart and muscle cell respiration by improving their functioning without oxygen and as a result may help with endurance and stamina and so also reduce the risk of cardiovascular disease. The potential benefits of Vitamin E in preventing cardiovascular disease may partially stem from its ability to inhibit smooth muscle cell profileration. 1 In addition Vitamin E has also been used to neutralize free radicals generated during surgery, in particular cardiopulmonary bypass surgery and could protect the body against some of the toxicity of gases used in anesthesia.

 

Anti – Aging.

Telltale signs of aging such as skin changes and tissue degeneration can be caused by free radical damage to cells which are unprotected by antioxidant nutrients such as Vitamin E. Applied topically it has also been used to reduce scarring, help prevent dry skin and stretch marks and assist in the repair of skin ulcers and burns. As such Vitamin E is used in many anti-aging and beauty products available on the market today.

 

Womens friend.

Women should find Vitamin E particularly helpful as it has been found that the Vitamin E in starflower and evening primrose oil can help to reduce the hot flushes often experienced during menopause. A study in 1984 led by Dr Wald at St Bartholomew’s Hospital in London, United Kingdom also found that women with the lowest Vitamin E levels have the highest risk of breast cancer. 2

Another study measured the blood levels of Vitamin E and selenium and it found that those women within the top third of those with high levels of these nutrients, had a 91% decreased risk of cancer.

A double-blind, placebo-controlled study reported in The Lancet, involving 160 pregnant women at the risk of toxaemia showed that Vitamin E may be of benefit during pregnancy also. In the study some of the women were given an antioxidant supplement of 1 gram Vitamin C and 400 IUs Vitamin E daily, from weeks 16-22 until the end of pregnancy and the rest were given a placebo. The group taking the antioxidants had a 76 percent lower incidence of preeclampsia than the group taking the placebo. 3

 

Prostaglandins.

 Vitamin E is one of five nutrients(these are: Zinc, Magnesium, Vitamin E, Vitamin C and Vitamin B6 ) needed for the body to manufacture prostaglandins, which among other functions, help to regulate calcium movement in the body, control cell growth, control hormone regulation and sensitize spinal neurons to pain. Vitamin E helps to  reduce PMS symptoms because of its regulatory role in prostaglandin production. In particular  prostaglandins help to reduce cramps and breast tenderness.

 

Essential Fatty Acids.

Vitamin E helps to ensure maximum absorption of essential fatty acids (EFAs), also know collectively as Vitamin F. EFAs are responsible for, among many other things, normal growth, behaviour, maintenance of cell membranes, a working immune system and a balance in hormone levels. In natural nutrition, when a person is not capable or ready to take EFAs orally then Vitamin E is applied topically in order to maximise EFAs absorption from dietary sources until the body is able to handle taking the oils by mouth. This is usually done after a bath or shower as an oil in the form of evening primrose oil and is applied to the inner thighs and the inner parts of the upper arms.

 

Vitamin E and Diabetes.

Treatment with Vitamin E  appears to be effective in normalizing retinal blood-flow abnormalities and improving kidney function in insulin dependant (type 1) diabetes. Many diabetics have decreased blood flow at the retina of the eye and can suffer from diabetic retinopathy, a degenerative eye condition which can cause vision loss. In a clinical trial patients receiving high doses of Vitamin E for 4 months experienced improved kidney function and a near normal rate of retinal blood flow. 4

 

What else is it good for?

In his book, ‘Staying Healthy with Nutrition’, Elson M Haas, MD, suggests the following as possible other uses of Vitamin E taken orally: peptic ulcers, anemia, periodontal disease, shingles, autoimmune diseases and dermatitis. He also suggests that Vitamin E protects against the toxic effects of smoke, alcohol and ozone and when applied topically  can be used for lupus rash, herpes infections and skin ulcers among other afflictions.

 

Deficiency.

There is no deficiency disease for Vitamin E as opposed to Vitamin C or many of the B vitamins, thus a deficiency of this vitamin is often very difficult to diagnose. Biochemically, low levels of Vitamin E can be measured in the blood and have been seen in conditions such as acne, anemia, infections and certain dementias such as Alzheimers disease. If you suspect you have a severe Vitamin E deficiency, consult your GP and a recognised nutritionist who will be able to work out a supplement programme tailored to your personal needs.

 

Supplements.

If taking a Vitamin E supplement the recommended dietary allowance (RDA) in South Africa has been established as the following:

Children 4-6 years of age: 9 IUs

               7-10 years of age: 10 IUs

Males from 15 years of age: 15 IUs

Females from 15 years of age 12 IUs

Pregnancy: 15 IUs

Lactation: 18 IUs

As always, consult with your GP, dietician or nutritionist before embarking on any supplement programme.

 

Food sources.

Vitamin E can be found in nature in a variety of foods. Among these are: wheat germ oil, olive oil (cold-pressed, extra virgin), safflower oil, corn oil, soybeans, nut oils, spinach, asparugus, kale, celery, tomatoes, egg yolk, butter, milk fat and liver. The oil component of all nuts, seeds and grains contain tocopherol but processing can often destroy this valuable vitamin so be sure to use cold-pressed oils and raw, unroasted nuts and seeds if you are trying to increase your dietary intake of this vitamin.

 

Nature provides us with many nutrients which we need to function with optimal health and vitality, of these, Vitamin E is a shining example of just how perfectly we are provided for. Ensuring that you have an optimal intake of this and other vitamins is easy if you focus on natural and unprocessed foods and always remember to read your labels and ask questions if you are not sure of how a food is manufactured or stored. Be adventurous in your food choices and explore all the riches that natures bounty has to offer because personally, I suspect, in the next few years, we will discover even more benefits that have been ‘hidden’ in these natural powerhouses all along.

Carrier or Base Oils

Carrier Oils act as a medium for essential oils which are very concentrated and are blended into the carrier oil in low dilutions ( 3% ). This means that you will add a maximum of three drops essential oil per teaspoon carrier oil.

Carrier oils are usually extracted from seeds and fruit and are called fixed oils because they are not volatile. The chemical structure of vegetable oils is such that it is easily absorbed through the skin and also has therapeutic properties of its own.

While the vitamins and minerals of the different carrier oils have a role to play,it is the concentration of essential fatty acids,the presence of anti-oxidants and natural tocopherol (Vit.E ), that determine the ultimate benefit the carrier oils offer. EFA s are free radical scavengers and can protect the skin from pollution and sun and wind damage. Carrier oils containing Gamma Linoleic Acid (GLA ) are important for healthy cell functioning and regeneration of skin cells. Carrier oils containing Vit.E promote soft and supple skin and act as a natural preservative.

Invest in quality, cold-pressed organic oils and store in dark glass bottles in a cool place. Create your blends in small quantities as exposure to light and oxygen over a period of time may turn the carrier oil rancid. Choose your carrier oils for the specific purpose you need it for,be it massage oil, bath oil, skin oil or barrier cream. Those with sensitive skin, should always do a test patch and people with a severe reaction to nuts should rather not use nut oils.

Almond Oil(Prunis Amygdalis var. dulcis)

Has been popular through the ages for use in face and hand creams. It can be used for all skin types and its concentration of oleic and linoleic essential fatty acids makes it a great moisturiser,soothing to itchy and inflamed skin,and a good lubricant and conditioner for the skin. It is used extensively on its own as a massage oil because of its light and non greasy nature.

Apricot Kernel Oil (Prunis Armenica)

Contains useful levels of EFA s, has a light texture for easy absorption and blended with other oils such as almond and sesame, offers enriching and nourishing properties for dry , damaged skin.

Avocado Oil (Persea Americana )

Traditionally used as a beauty oil by women in Mexico, avocado oil is rich in proteins and Vitamins A,B,D.,and contains anti-oxidants which gives it a long shelf life. Cold pressed, the oil is thick and viscous and is better used as addition to another carrier oil. Avocado oil is good for dehydrated skin and has the ability to penetrate into the deeper layers of skin. It also act as a natural sunscreen.

Grapeseed Oil (Vitus vinifora)

Grapeseed oil is popular as a massage oil as it has a light texture with good lubricant quality and is an odourless carrier for essential oils. It contains some Vit. E ,minerals and vitamins. Critcism against grapeseed oil is that it is obtained by hot extraction methods or solvents and is thus not as “wholesome” as cold pressed oils.

Olive oil( Olea europa )

Olive oil has been extensively used since ancient times,as food as well as massage oil.Olive oil has a high concentration of anti-oxidants as well as chlorophyll and carotenoids.This makes olive oil good to assist cell regeneration,to stimulate and nourish the skin,as well as softening and preserving the skin. Olive oil has an antiseptic and anti-inflammatory action due to its polyphenol content. Olive oil is used as a base for ointments, but blended with other oils for use as a massage oil.

Sesame Oil (Sesasum indicum )

Sesame oil is a clear pale yellow oil ,rich in minerals and vitamins and have a high Vit. E content. A natural moisteriser,it nourishes and detoxify the deeper tissue layers. A natural sunscreen ,it is also good for sensitive skins and has antiseptic properties. A good carrier oil to use on its own or as part of a blend.

The above carrier oils are readily available from health shops to offer their unique qualities to your skin and massage oil blends. Some specialized carrier oils are available to use in small quantities to enhance your blends even more.

Specialized Carrier Oils.

Evening Primrose (Oenorthera biennis )

Evening Primrose Oil is well known for its health benefits and are taken via capsules internally. As a carrier oil, it is used in small quantities in a blend where it acts as a preservative to the base oil,as well as bringing its unique qualities to the blend.The high GLA content of evening primrose oil moisturises and nourishes the skin,counter-acting premature aging. It has a beneficial effect on skin conditions such as eczema,psoriasis and dermatitis.

Jojoba Oil (Simmondsia Chinenses )

Extracted from the beans of this desert scrub, jojoba oil is a waxy substance,akin to sebum, making it an excellent lubricant, beneficial to all skin types. A natural sunscreen, jojoba oil is easily absorbed into the deeper layers of skin, is softening, moisture retaining and protective to the skin. Add to other carrier oils.

Rosehip Seed Oil ( Rosa mosqueta )

A wonder oil derived from the seeds within the rose hips,it is high in essential fatty acids, GLA and Vit. C. Research has found rosehip oil excellent for the healing and regeneration of damaged tissue. Rose hip oil has been used to treat burns, scars, ulceration of the skin,and radiation burns. Rose hip oil used as a night oil,is good for dry and aging skin. Blend in any dilution with carrier oils.

Wheatgerm Oil (Triticum vulgare )

A natural oil with a high Vit. E content, wheatgerm oil is used at a 10% dilution in other carrier oils for its anti-oxidant properties to increase shelf life. Wheatgerm oil will benefit dry or mature skin. Buy wheatgerm oil in small quantities and keep refrigerated.

A good quality vegetable , seed or nut carrier oil will enhance your skin as well as offer a wholesome medium for your chosen essential oils. Creating your own personalized blends is a satisfying process and good for body ,mind and soul.
