|Article: The Role Of Vitamin A In Hearing Loss and Tinnitus - by Louise Diesel|
Some questions I am most often being asked concern the importance of vitamins in our diet, the effects of vitamin deficiency, and most often, the reasons why we have included the particular supplements that we have in our Alpha Tinnitus Relief Formulas.
Since Vitamin A plays a vital role in the Alpha Tinnitus Relief Formulas, I felt that some information on Vitamin A, it's uses and it's importance to your body's correct functioning was appropriate.
Vitamin A has been shown to be vital to inner ear health and in preventing inner ear damage. It has also been proven to be effective in restoring hearing loss if taken within a short period after the hearing loss has occurred.
One of the problems facing mineworkers and musicians (and all of you who are exposed to noise in the workplace) for instance, is the fact that ear plugs are really only effective when correctly placed into the ear canal.
If these ear plugs are not correctly inserted, inner ear damage, hearing loss and tinnitus will occur.
Recent studies have shown that Vitamin A supplementation whilst the subject is being exposed to sustained loud noises in the workplace, has been effective in reducing noise induced hearing loss and tinnitus in industries.
When we were formulating the ALpha Tinnitus Relief Formula capsules we decided rather to include Natural Beta-Carotene in the formulas as opposed to Vitamin A.
Beta-carotene is a fat-soluble plant compound that is a member of the carotenoid family.
Carotenoids are the pigments that provide the red, yellow, orange, and green colors of fruits and vegetables, and more than 500 different carotenoids have been identified.
The primary dietary carotenoids are beta-carotene, alpha-carotene, lycopene, lutein, zeaxanthin, and beta-cryptoxanthin.
The reason we chose to include Beta-Carotene in our formulas is simple....
Your body converts Beta-Carotene into Vitamin A.
Your body only converts sufficient Beta-Carotene into Vitamin A to sustain its Vitamin A requirements.
Beta-Carotene also acts as a powerful antioxidant.
All the Beta-Carotene that is surplus to your body's requirements is quite simply flushed away.
This is absolutely the safest way to supplement your Vitamin A needs and to ensure that you will never be Vitamin A deficient whilst at the same time ensuring that your intake of Vitamin A is never too high!
That's the reason you will not find any Vitamin A in our capsules!
Vitamin A Information
Vitamin A was the first vitamin to be discovered. It was identified as a necessary growth factor in 1913.
Vitamin A is obtained from food in a combination of two different forms.
1] as pre-formed vitamin A and
2] as pro-vitamin A which the body can convert to vitamin A as necessary.
Pre-formed vitamin A, often in the form of retinol or retinal, is found in foods of animal origin.
Pro-vitamin A, of which beta-carotene is the best known form, is found in orange, yellow and dark green vegetables and fruits.
Why does your body need vitamin A?
Vitamin A is essential for the eyes to function effectively. It is involved in the growth and repair of the eye and in the production of a chemical called visual purple, which helps in night vision.
These cells cover the internal and external surfaces of the body and are found in the skin, lungs, developing teeth, inner ear, cornea of the eye, sex organs, glands and their ducts, gums, nose, cervix and other areas.
Vitamin A is involved in the growth and repair of epithelial cells.
This growth and maintenance role is vital for most bodily functions. For example, the good health of the digestive tract lining is vitally important in protecting against ulcers and maintenance of the lining of the vagina and uterus is important in fertility.
Vitamin A is of vital importannce in the development of the embryo.
Vitamin A is involved in the production of membranes and of myelin, which coats the nerves.
GLANDS AND HORMONES
Vitamin A is also important the maintenance of the adrenal gland and synthesis of certain hormones such as thyroid hormone.
THE IMMUNE SYSTEM
Vitamin A is also known as the anti-infective vitamin as it is vital for the development of the body’s barriers to infection.
Vitamin A stimulates and enhances many immune functions including antibody response and the activity of various white blood cells. This immune enhancing function of Vitamin A promotes healing of infected tissues and increases resistance to infection.
Adequate vitamin A intake, either from diet or supplements, is very important in preventing sickness and death in children. Many studies have found that vitamin A supplementation reduces the risk of infectious diseases in areas where vitamin A deficiency is widespread.
A recent research review analyzing the results of several studies found that adequate vitamin A intake in children resulted in a 30% decrease in deaths from all causes. Children in developing countries are often at high risk of vitamin A deficiency.
In developed countries, ensuring adequate vitamin A intake is particularly important in those with life threatening infections such as measles and in those at risk of relative deficiency, such as premature infants.
GROWTH AND BONE FORMATION
Vitamin A is necessary for growth and the formation of bones and teeth, collagen synthesis, cartilage synthesis and wound healing.
Many studies suggest that high blood levels of vitamin A can help prevent certain forms of cancer, particularly cancers of epithelial tissue.
A recent study of 89 000 nurses found that those in the top 20% for vitamin A intake were significantly less likely to develop breast cancer than those in the bottom 20%.
This may be due to the importance of vitamin A in maintaining healthy epithelial cells, strengthening the immune system and stimulating the response to abnormal cells.
Laboratory experiments have shown vitamin A to have antiviral activity.
The presence of fat and bile in the intestines is necessary for vitamin A absorption
Around 80 to 90% of vitamin A in the diet is absorbed although this is reduced in older people and those who have trouble absorbing fat, such as pancreatitis, celiac disease and cystic fibrosis sufferers, who may run the risk of vitamin A deficiency.
Vitamin A is joined to fatty acids in the intestinal lining, combined with other substances and transported to the liver, which stores 90% of the body’s vitamin A.
Vitamin A deficiency is relatively rare in developed countries and is usually limited to those who have absorption difficulties, liver disease or who drink a lot of alcohol.
Vitamin A deficiency is common in alcoholics and contributes to some of the disorders of alcoholism such as night blindness, skin problems, cirrhosis of the liver and susceptibility to infections.
Vitamin A deficiency symptoms
One of the first symptoms of deficiency is night blindness due to lack of visual purple. Prolonged deficiency leads to xerophthalmia, a condition in which eyes become dry, ulcers appear on the cornea, the eyelids become swollen and sticky and which eventually leads to blindness. Vitamin A deficiency is the leading preventable cause of blindness in developing countries.
Prolonged deficiency leads to thickened dry skin which is prone to infections. Small hardened bumps of a protein known as keratin may develop around the hair follicles.
Deficiency causes growth retardation, weight loss, diarrhea, thickening of bone shafts, congenital malformations, impaired hearing, taste and smell, wasting of testicles and reduced sperm count. Inadequate vitamin A intake can may lead to improper tooth formation in children and to gum disease.
Epithelial surfaces are adversely affected by vitamin A deficiency causing increased susceptibility to skin and respiratory infections. Immune cells and antibody functions are also affected which may lead to an increase in pre-cancerous cells in the epithelial tissues of the mouth, throat and lungs.
A deficiency of vitamin A can contribute to lower levels of active thyroid hormone with symptoms of low body temperature, depression, difficulty in losing weight, headaches and lethargy.
Vitamin A supplements are used to prevent or treat deficiency and in developing countries to protect against or treat measles and other viral infections.
CANCER - Many studies suggest that high blood levels of vitamin A can help prevent certain forms of cancer, particularly cancers of epithelial tissue. A recent study in Western Australia found that miners who had been exposed to carcinogenic substances had less risk of cancer when given 7500 mg RE per day.
The vitamin A derivatives etretinate and isotretinoin are used to treat psoriasis. These compounds inhibit the formation of some of the toxic compounds which may be responsible for the high rate of cell division causing the scaly build up on the skin.
Other uses of Vitamin A
Vitamin A eye drops have been used to treat dry eyes.
Creams containing vitamin A have been used to heal wounds in patients taking corticosteroid drugs.
Vitamin E and zinc are necessary for vitamin A metabolism, including absorption, transport and release from the liver. Vitamin E may protect against some of the effects of excess vitamin A.
Vitamin A is necessary for calcium metabolism in the formation of healthy bones and teeth.
Smokers may have increased needs for vitamin A and beta carotene in order to protect against free radical damage.
Vitamin A is destroyed in the body by mineral oil laxatives, which bind it. Antacids, the anti-gout drug colchicine, and the cholesterol reducing drug, cholestyramine inhibit vitamin A absorption.
Alcohol irritates the digestive tract and inhibits the absorption of vitamin A while also depleting the body’s tissue stores.
Vitamin A supplements should not be taken with isotretinoin or etretinate for skin disease or in cases of impaired liver or kidney function. If vitamin A supplements are taken with large amounts of alcohol, liver damage may occur.
Broad spectrum antibiotics should not be taken with high doses of vitamin A.
The dosage of 10mg Beta-Carotene found in each Alpha Tinnitus Relief Formula Capsule is roughly one quarter the recommended daily allowance for Vitamin A.
The Beta-Carotene found in Alpha Tinnitus Formulas is completely natural in origin (it is extracted from plants), and the recommended daily dosage of four capsules will supply the correct daily amount of Vitamin A to your system.
As discussed above, much of the Vitamin A we take in from our food intake is actually destroyed or simply passes right through the system as a result of bad eating habits, alcohol intake, and in a lot of cases, by the prescription drugs we take.
You will also notice that we have also added Vitamin E and Zinc to the capsules as they actually help Vitamin A to metabolize, but more about that in a future edition.
We believe that we have created the ideal formula. A formula that not only will relieve your tinnitus, Hyperacusis and Meniere's Disease, but also one that will lead to all round health and happiness.
