The Importance And Benefits Of Vitamin K

One of the not no famous vitamins, but also vital for our healthy living is Vitamin K.
Its most important role is in the blood coagulation. It heps us stop bleeding and getting healthy again after we get cut. Persons with deficiency in Vitamin K have the tendency to excessive bruising and/or nose bleeding. These can cause grave problems if are seriously hurt, as they bleed for a long time.

Approximatively half of our daily dose of vitamin K, is taken from leafy, green vegetables as broccoli, asparagus, spinach, sweet potatoes, apricots. Also it is contained in vegetable oils like olive, canola and soybean oils.

Other easy to find sources of K vitamin are yogurt and some cheese; a liquid form of this vitamin is found in green tea and - surprisingly- in coffee.

I know we all are trying to avoid fats, but sometimes they are needed. Some nutrients are fat soluble -like vitamin K, A, D, E and F. With other words, for their absorption it is necessary to come into contact with some oils, fats.

There are more K vitamins: K!and K2 are fat-soluble and can be found in natural sources; K3 is the synthetic version for t people who cannot consume vitamin K naturally because they lack bile, an enzyme necessary for fat-soluble vitamins absorption.

Vitamin K has another important function: to improve the bone health and reduce risk of bone fractures, especially for post menopausal women, as they have the risk to get osteoporosis.

The majority of us will never have to worry about our body's vitamin K intake, but it's always good to know.
Although it is not so popular, Vitamin K has also been found to have cosmetic benefits.

Eye Supplements In Addition To Vitamin A

We all take our eyes and sight for granted, and that's ok cause we are born with them, but we only pay attention to them when some illness or trauma occurs. Sometimes it can be too late as our whole life is affected. There are many methods to take care of our vision, one of the prior importance is nutrition.

Of course we cannot control all the factors that involves the eye's health, but there also are a lot of them that we can prevent. Natural vision problems are caused by age, smoking, sunlight, obesity as well as the intake of many medications. The age related worsening (the most popular) can be delayed by means of nutrition.

It was proven that antioxidants from certain foods have an especially healthful effect on our eyes. Unfortunately far not everyone eats enough fresh produce - either because of the busy style of life, or just can't afford it.

Nowadays its very easy to find all the vitamins and supplements on the market, among them the A, C and E vitamins (antioxidants) have an influence on the eye health.

Vitamin A can be found in meals like eggs, liver, milk, carrot. It is involved in the formation and maintenance of healthy skin, hair and helps us to see in dim light, preventing night blindness for pregnant women.
Our eyes deteriorate without adequate supplies of vitamin C. An indication of its importance is the fact that the concentration of vitamin C in the vitreous humor (the clear liqud in the eyeball) is about twenty-five times our serum level (the level in our blood), the retina 100 times.
The antioxidant qualities of vitamin C help prevent crystallization and accumulation of foreign molecules that result in the blurred vision of cataracts.

People with lower levels of vitamin E in their blood have a higher risk of cataracts and macular degeneration.

Not less important for the vision are the beta carotene, selenium, cupric and zinc oxide, lutein. Smokers should take care to take enough luteine as it is important to the retina.

Eye sight vitamins can be bought without a prescription unless it is a high dosage for certain people who have AMD and require an extra dosage. Over the counter vitamins are usually not expensive and provide most or all of the vitamins and nutrients listed on our eye nutrition page. Normally dosages range from 1 to 4 pills a day but these will vary with the amounts of vitamins and minerals in each pill. It is also good to note that although these vitamins and minerals are good for us, a moderate amount is all we need because taking too much of them can be dangerous.

Herbs And Vitamins For Better Memory And Longer Life

It is becoming increasingly popular to take supplements containing herbs and vitamins for better memory and longer life. Not only are well known traditional remedies for specific aging problems being used, but there is a lot of investigation and research being carried out in Asia and Europe on the natural and herbal remedies of yesteryear.

There have been several new remedies suggested over recent years for short and longer term loss of memory, and most of these are also recommended to improve intelligence and mental capability. The so-called ‘smart pill’ ginkgo biloba is a case in point, and this plant is under constant investigation with regard to its effect on Alzheimer’s sufferers.

The number of different herbs and plants, and the type of chemicals they contain, is massive, including various nutrients, antioxidants, hormones, enzymes and amino acids. The list of herbs under investigation is almost unlimited, though you have to be careful with some of them. Kava kava, for instance, helps stress and anxiety, and has been shown to have a positive effect in suppressing the growth of cancer cells.

For other reasons, however, it is banned for sale in parts of Europe, including England, though the reasons for this are currently under review. It is commonly used throughout the Pacific for its soporific effect, but can cause skin and other problems if overused. Where it can be purchased, however, its use is thought to prevent the onset of some cancers including leukaemia.


Another supplement that is contentious in its use is the Human Growth Hormone. This is used as a supplement in adults suffering from GH deficiency, and has been promoted as an anti-aging supplement. Whether or not it has this effect is still open to debate, though it certainly increases lean muscle mass and bone density in those with a deficiency. The first step in an anti-aging program should be to ensure that your GH level is as it should be.


The real mind boosting herbs and supplements are those that claim to boost the memory, cure memory loss and treat Alzheimer’s disease. The queen of them all is probably ginkgo biloba, studies on which have provided evidence that it can be beneficial in improving the brain and memory function in early stage Alzheimer’s, and in age-related cognitive decline (ARCD). It is also believed to help in cases of certain types of glaucoma. These benefits might be due to the effect is has of increasing the circulation of the blood to the brain.

Ginkgo is also a powerful antioxidant that can protect the central nervous system from the effects of aging, and protect the cardiovascular system through the destruction of free radicals in the blood. Free radicals can be responsible for mental deterioration and dementia in the elderly. Gingko biloba contains a number of different active antioxidants and chemicals that improve blood circulation to the brain.


It is not only the ancient remedies that are being found to have a scientific reason for their effectiveness in treating specific conditions, and Coenzyme Q10 is one of the relatively newer additions to nature’s arsenal. This substance is contained in every cell in the body, and it has been found to provide protection to the brain from Parkinson’s disease and other conditions that cause degeneration of the brain cells. This can help to improve memory, and reduce the effects of aging, though it does not relieve any existing Parkinson’s symptoms.

Studies into the effects of Coenzyme Q10 are still under way, and it has been shown to be a strong antioxidant. It is also believed to reduce high blood pressure though this is still under review, and studies into the potential uses of the supplement are continuing.


Although used extensively over the ages for a large number of ailments, bilberry is generally regarded by experts as being another strong antioxidant. In fact most supplements that have an anti-aging effect appear to be antioxidants. This is because aging is closely associated with the presence of free radicals in the blood, and even the traditional antioxidants vitamins C and E can have an anti-aging effect on the body.

Bilberry has been used for the treatment of arteriosclerosis and various eye conditions such as macular degeneration and cataracts, and is commonly available. It contains flavonoids that can reduce the risk of blood clots, and hence of strokes and heart attacks. Although many of the medicinal properties claimed have yet to proved, bilberry is widely used as an herbal supplement.


Pumpkin is also high in antioxidants, and it is considered by the Chinese to stimulate the insulin-producing cells in the pancreas. The effect of increased insulin levels is to reduce the sugar levels in the blood, and reduce oxidation damage to certain cells in the body. It is being regarded as a possible natural treatment for diabetes that should reduce sugar imbalances and therefore have an anti-aging effect.


DHA is dicosahexaenoic acid, otherwise known as DHA, and is found predominantly in fish oils. Trials are currently under way with this material on humans in the treatment of Alzheimer’s disease where it appears to reduce the formation of plaques in the brain. DHA used be found in cattle and eggs, but this has reduced considerably due to cattle being taken off grass some time before slaughter and there is less DHA in factory eggs.

The synthetic supplement is synthesized from beet though is more expensive than the marine source. This supplement is also effective in those that suffer from heart disease.

There are many other natural supplements that have an anti-aging effect or that improve the memory. Most work by means of their antioxidant content, and there are new studies being carried out continually throughout the world. China is a rich source of such remedies, and as that country opens up more will be known about the scientific basis behind their pharmaceutical applications.

There is little doubt that the use of herbs and vitamins for better memory and longer life has a strong scientific basis, and that we still have a great deal to learn about the remedies used before the introduction of mass produced pharmaceuticals.
