Benefits Of Vitamin E

Oxygen is one of the primary components of nature that supports life. The same oxygen, when inside the body, through certain molecules, becomes overly reactive and starts causing damage through the formation of free radicals. This is called oxidative stress. Vitamin E, as an antioxidant, helps prevent oxidative stress, thereby preventing cell damage and aging of the cells.

The body absorbs cholesterol, a fatty substance in foods, and this is transferred from the liver to different tissues to be stored as fats. They are carried in the bloodstream by a molecule called Low Density Lipoproteins (LDL). When LDL gets oxidized, they react with cholesterol and a waxy fat substance called plaque is deposited on the walls of the arteries, which results in the stopping of blood flow, high blood pressure and cardio-vascular diseases.

Vitamin E helps prevent the conversion of cholesterol into plaque, and this is done by alpha-tocopherol, not any other form of vitamin E, because liver places it preferentially in the bloodstream through a protein called alpha-tocopherol transfer protein.

The effect of vitamin E in preventing cancer has not conclusively been established. According to a study by The American Association of Cancer Research, reduced risk of cancer is associated with an intake of vitamin E-rich foods. Contradictorily, a study done by Iowa Women’s Health Study finds little evidence that vitamin E has protective effect against breast cancer in women after menopause. Hence, researchers have noted that not just vitamin E alone, but foods rich in antioxidants may be able to protect from cancer.

Numerous studies have established the effect of vitamin E in protecting the skin from ultraviolet radiation, whose harmful effects include photodermatitis, an allergic type reaction to the UV rays of the sun. Vitamin E, whether taken through foods or applied topically, has been shown to protect skin cell membranes.

Besides these benefits, vitamin E may protect from Alzheimer’s, cataracts (clouding of the lens of the eyes), and pancreatitis (inflammation of the pancreas). Also, vitamin E may be beneficial in healing wounds and burns, reducing scars. The property of combating oxidative stress may be useful for athletes, as their oxygen utilization rate is higher than those not doing exercise, which results in increased generation of free radicals.

Without proper conclusions from studies, it would be premature to opt for supplements without the advice of medical practitioner. However, it is generally recommended to take several servings of vegetables and fruits that are rich in antioxidants.

Benefits Of Vitamin B12 (Methylcobalamin) Supplementation

One of the most overlooked supplements on the market is Vitamin B12.Your body needs this vitamin, in combination with other B vitamins, to maintain a healthy nervous system, maintain energy levels and production of good DNA. All very important processes to your everyday existence.

The number one symptom for Vitamin B12 deficiency is feeling tired and lethargic. The B-Complex vitamins play an important role in carbohydrate digestion and energy production. Without all of the proper components this system can breakdown and cause a these symptoms. If left without diagnosis or treatment, B12 deficiency can lead to a serious medical condition, Pernicious Anemia. The symptoms of B12 deficiency include; shortness of breath, fatigue, rapid heart rate, loss of appetite, diarrhea, tingling and numbness of hands and feet, sore mouth, unsteady gait, especially in the dark, tongue problems, impaired smell and bleeding gums. A high intake of Folic Acid can hide B12 deficiency. This condition is easily fixed by adding B12 rich foods to your diet or taking supplements. In most cases, Vitamin B12 should be taken in conjunction with a Folic Acid supplement and a B-Complex vitamin.

Because of changing diets, and highly processed food, there has been a significant increase in Vitamin B12 deficiency. Vitamin B12 is found in red meat, eggs, dairy and fish. There are no know sources of Vitamin B12 in vegetables. At one time it was quite common to feast on organ meat, but you would be hard press to find a fast food restaurant serving steak and kidney pie or liver and onions! The modern diets has led to a decline in nutritionally balanced diets. The highest sources of B12 can be found in mollusks/clams (85 micrograms per 3oz portion) and beef liver (47 micrograms per 3oz portion). Over cooking can lead to the breakdown of the vitamins. If those are not to you your liking then salmon, trout and beef are moderate sources with about 5 micrograms per 3 oz portion. Over cooking these foods can significantly reduce the quantity and quality of nutrients.

If oysters and organ meat are not to your liking then Vitamin B12 supplements will work perfectly well. There are a number of forms of B12, and this list will help you pick the proper supplement for your conditions. When in doubt, contact your doctor or use Methylcobalamin.

Methylcobalamin is a coenzyme form of Vitamin B12 which is biologically active. This means that your body can use it as is, and does not require any metabolic steps to make it body friendly. The product comes in a sublingual tablet(dissolves under your tongue) because your digestive system modifies the molecule. The sublingual method allows the vitamin to directly enter your bloodstream, providing rapid benefits.

Cyanocobalamin is a synthetic, and inactive, form of Vitamin B12 that requires a number of metabolic processes to gain any benefit. This can be problematic in people with certain deficiencies and health issues. Unfortunately, this is the most common form of Vitamin B12 on the market and is found in most Vitamin B-Complex’s.

Hydroxycobalamin is a non-active form of Vitamin B12 and is used commonly as an injectable form. It has a number of benefits depending on your condition. It is recommended for those who have cyanide sensitivity. Hydroxycobalamin helps the body bind free cyanide, by reacting with the molecule to form cyanocobalamin, which can then be excreted from the body. Most people are aware that cyanide is highly toxic, but the body regularly uses it in very small quantities for metabolic processes.

Adenosylcobalamin is the other coenzyme form of Vitamin B12 and is biologically active. This form is usually sold as an injectable form and only available by prescription.

Common Reasons for Vitamin B12 Deficiency

There are a number of reasons why a person may have Vitamin B12 deficiency. Some people lack the proper intrinsic factor to properly digest this molecule. Many times this will show up at a young age but may occur as you age, however many times it is not diagnosed properly.

Vegan’s also may be deficient because their diet does not allow them to eat sources of food derived from animals. Unfortunately, Vitamin B12 is only found in animal sources. Taking supplements of B12 will ensure that there are no issues.

It is also recommended that elderly people take Vitamin B12 supplements. It has been shown in studies that 15% of people over 65 have Vitamin B12 deficiency. This is partially caused by a decline in the gastric system, which results in poor absorption of nutrients. The preferred source of B12 for the elderly is sublingual or injectable forms, since they bypass the digestive systems.

Another culprits for B12 deficiency is gastric acid-blocking products and medication, which can lead to decreased vitamin B12 levels. This is also related to people with malabsorption conditions such as Celiac disease, low stomach acid or those who have had stomach or intestinal surgery. Any stomach condition may result in poor absorption of nutrients.

Vitamin B12 is a very safe, and affordable, supplement with real benefits. For anyone that is concerned about their health, proper supplementation can play a very important role. If you have any of the symptoms or conditions associated with Vitamin B12 deficiency try taking a coenzyme form of B12, usually Methylcobalamin, and a B-Complex Vitamin with Folic Acid for a two week period. If you notice any benefits, great, and if not there was no harm done. You should always check with your doctor if your symptoms continue.

One interesting thought about Vitamin B12 is that oysters were documented as a aphrodisiac food by the Romans in the second century. Could it have been that many Romans were deficient in B12, and when they ate the oysters, which are high in B12, they were no longer deficient resulting in an increase in energy and youthfulness? It’s possible.

Benefits Of Vitamin B12

Vitamin B12 is a safe, reliable and inexpensive vitamin. For health-conscious individuals, a regular intake of a prescribed amount of vitamin B12 is a key element for preserving a balance in the human body. B12 could be obtained from food sources or could be taken in the form of supplements orally or via injections.

In combination with other B-group vitamins, vitamin B12 ensures the smooth functioning of vital life processes of the human body. It is important for maintaining a healthy nervous system and DNA production. Vitamin B12 helps to regulate the formation of red blood cells in the body. Other benefits of vitamin B12 include its role in maintaining and increasing energy levels in the human body.

Vitamin B12 is highly beneficial in various forms. Methylcobalamin, the coenzyme form of vitamin B12 is a body-friendly version, which means that no metabolic steps are required for its ingestion and it can be used it in its normal form. It is available as a sublingual tablet that dissolves under the tongue (because the digestive system might modify this molecule). Through this method, vitamin B12 can directly penetrate the bloodstream and yield numerous benefits. Hydroxocobalamin is another form of vitamin B12 that has been recognized as an effective cure for cyanide poisoning.

Research studies reveal a clear, inverse correlation between homocysteine (an amino acid found in the human body) levels and vitamin B12 levels. Blocking the formation of homocysteine leads to endothelial dysfunction (a narrowing of the arteries) and is a precursor of atherosclerosis; vitamin B12 helps to curb atherosclerosis. A supplement of vitamin B12 also augments the efficiency of folic acid’s capacity to lower homocysteine levels. Researchers are of the opinion that in conjunction with folic acid, an adequate dose of vitamin B12 helps to counter heart diseases and thrombosis. The synthesis of S-adenosylmethionine (SAMe), a compound involved in immune function and mood, depends on the association of folate and vitamin B12.

Studies indicate that absorption of Vitamin B12 decreases with an increase in age. Hence, an increased intake of vitamin B12 is extremely useful for adults above fifty. The recommended form of intake is in supplement form, since elderly people absorb this form better than food forms of vitamin B12. A supplementation of vitamin B12 aids in the cognitive function and heals neurological impairment within this group.

In most cases, vitamin B12 should be taken in conjunction with a folic acid supplement and a B-Complex vitamin. The good news is that while an intake of vitamin B12 facilitates functions necessary for everyday existence, an extra dose causes no harm but instead could be stored for future use.

Benefits of Supplementing With St. John's Wort

What is St John's Wort?
Extracts of Hypericum perforatum L. (St John's wort) are now successfully competing for status as a standard antidepressant therapy. Because of this, great effort has been devoted to identifying the active antidepressant compounds in the extract. From a phytochemical point of view, St John's wort is one of the best-investigated medicinal plants. Researchers in Europe have studied St John's Wort for decades. They discovered a combination of elements in the plant, foremost of which is "hypericin", react with specific chemicals in the brain to temper emotional discomfort, lift depression, and calm the nerves. Working very much like the common synthetic prescription antidepressants (maprotiline hydrochloride and imipramine), natural extracts from St. John's Wort have shown to relax and soothe the psyche with minimal side effects

St John's Wort Benefits
St. Johns Wort today has been found to be very beneficial in healing wounds and is especially good for dirty, septic wounds. St. Johns Wort has been used in case of putrid leg ulcers, that noting heals. Like the leach that was used not too many years ago for wound cleansing it does not destroy the healthy tissues and healthy cells but it cleans the dirt out of septic wounds. It helps reduce the inflammation in septic sores, in boils, in cellulite and lymhangitis.

The compound Hypericin was isolated from St. Johns Wort in 1942 and has been used as an anti-depressant for emotionally disturbed people. This tranquilizing quality from small quantities hypericin increase blood flow to stressed tissue. There is a reduced capillary fragility and enhanced uterine tone due to the increased Hypotensive blood flow.

St John's Wort Side Effects
The use of St. Johns Wort has been shown to demonstrate a side effect producing a photosensitivity. Hypericin is absorbed in the intestines and concentrates near the skin. An allergic reaction takes place when those with light fair skin are exposed sunlight. That exposure causes tissue damage and in some cases death has resulted. While taking St. Johns Wort one should avoid strong sunlight whether the skin is dark or light. There is a photosensitizing substance produced under the skin by this exposure to sunlight that causes the skin to burn.

Benefits
• relieves mild to moderate depression and anxiety.
• promotes restful sleep.
• improves capillary circulation.
• increases cardiac circulation.
• eases gastrointestinal distress.
• relieves discomfort associated with premenstrual syndrome.
• fights retroviruses.

Benefits of Supplementing With Creatine

What is creatine?
Creatine is an amino acid (amino acids are the building blocks of protein) which is made in the body by the liver and kidneys, and is derived from the diet through meat and animal products. Creatine (creatine monohydrate) is a colorless, crystalline substance used in muscle tissue for the production of phosphocreatine, an important factor in the formation of adenosine triphosphate (ATP), the source of energy for muscle contraction and many other functions in the body.

What does creatine normally do in the body?
In the body, creatine is changed into a molecule called "phosphocreatine" which serves as a storage reservoir for quick energy. Phosphocreatine is especially important in tissues such as the voluntary muscles and the nervous system which periodically require large amounts of energy.

Why do athletes take creatine?
Studies have shown that creatine can increase the performance of athletes in activities that require quick bursts of energy, such as sprinting, and can help athletes to recover faster after expending bursts of energy. Creatine is best for the serious bodybuilder. It helps increase muscle mass, rather than muscle endurance, so it’s not well suited for athletes participating in endurance activities. However, the increase in muscle mass may be due to water retention and not an increase in muscle tissue.

Why have I been hearing so much about creatine and neuromuscular disorders?
Two scientific studies have indicated that creatine may be beneficial for neuromuscular disorders. First, a study by MDA-funded researcher M. Flint Beal of Cornell University Medical Center demonstrated that creatine was twice as effective as the prescription drug riluzole in extending the lives of mice with the degenerative neural disease amyotrophic lateral sclerosis (ALS, or Lou Gehrig's disease). Second, a study by Canadian researchers Mark Tarnopolsky and Joan Martin of McMaster University Medical Center in Ontario found that creatine can cause modest increases in strength in people with a variety of neuromuscular disorders. Beal's work was published in the March 1999 issue of Nature Neuroscience and the second paper was published in the March 1999 issue of Neurology.

I want to start taking creatine -- is it safe?
For the most part, athletes haven't experienced adverse side-effects from taking creatine, although recently there have been a few reports of kidney damage linked to creatine usage. No consistent toxicity has been reported in studies of creatine supplementation. Dehydration has also been reported to be a problem while taking creatine.

Athletes generally take a "loading dose" of 20 grams of creatine a day for five or six days, then continue with a "maintenance dose" of 2 to 5 grams of creatine a day thereafter.

What are the side effects?
Little is known about long-term side effects of creatine, but no consistent toxicity has been reported in studies of creatine supplementation. In a study of side effects of creatine, diarrhea was the most commonly reported adverse effect of creatine supplementation, followed by muscle cramping.18 Some reports showed that kidney, liver, and blood functions were not affected by short-term higher amounts or long-term lower amounts of creatine supplementation in healthy young adults. In a small study of people taking 5–30 grams per day, no change in kidney function appeared after up to five years of supplementation. Muscle cramping after creatine supplementation has been anecdotally reported in some studies.

Benefits
• increases athletic performance
• increases muscle mass
• beneficial for muscular disorders

Benefits and deficiencies of Vitamins

Vitamins are compounds found in food, which help us to be fit and healthy. These organic compounds help in the functioning of the various metabolic systems of our body. Vitamins are found naturally in the various foods, which we consume and we can also obtain vitamins in the form of vitamin supplements. Vitamins also help to protect our body from diseases and infections. Vitamins are also essential for the formation of various enzymes and hormones of the body which control the metabolic activities such as digestion, circulation excretion etc. There are about eleven types of vitamins, which are essential for the human body. Vitamin A is essential for the proper functioning of our eye and it also acts as an anti oxidant preventing certain oxidizing chemical reactions, which cause harm to our body. Vitamin A can be obtained from green leafy vegetables, broccoli, carrot, sweet potatoes, pumpkin, papaya etc. The B group vitamins include thiamin, riboflavin, niacin, folic acid, cyanocobalamin and biotin. These are essential for the proper functioning of our nervous system and for the conversion of food in to energy by the body. It is also essential for the proper functioning of various metabolic activities of our body. Vitamin B is available from whole grains, beans, fish, lean meat, fruits and vegetables, dry fruits, nuts, milk, egg, soy beans, etc. Vitamin B-12 can be obtained only from animal sources such as liver, egg, meat, cheeses etc. B group vitamins are essential for the amino acid metabolism, nitrogen metabolism, and for the healthy skin. Vitamin C can be obtained from citrus fruits such as lemon, sweet lime, oranges, grapes, grapefruit etc. Vitamin C is essential for the prevention of diseases and infection. It also helps in the absorption of iron. Vitamin D can be obtained from sunlight. It is essential for the bones and teeth. It is also needed for the growth of our body. Vitamin E is an essential antioxidant. It can be obtained from whole grains, asparagus, wheat germ, corn, green leafy vegetables and seeds.

If you do not take a proper nutritious diet then you may suffer from vitamin deficiency health problems. Lack of Vitamin A can cause problems related to eyesight such as night blindness. Insufficient Vitamin B can cause diseases like Beriberi, Anemia, poor resistance to diseases, etc. Lack of Vitamin C causes gum bleeding, weakness, loss of appetite, tiredness etc. Insufficient vitamin D causes deformation of bones and teeth. Deficiency of vitamins in food leads to poor health. An effective way of filling the nutritional gaps due to poor eating habits is the use of vitamin supplements. These vitamin supplements can help us to boost our immune system and to build up stamina.

It is always better to take vitamins as a whole from food sources rather than synthetic vitamins. Taking synthetic vitamins is more like taking half vitamin and our body treats natural and synthetic vitamin differently. It is very essential to provide our body with natural nutrients for protecting various organs and body functions. Our body needs whole vitamins, which are found naturally in the foods such as grains, vegetables and fruits rather than vitamin supplements. Our body utilizes the natural vitamin more efficiently than the synthetic vitamin.

Bee Supplements For Your Health

Bee Pollen
Bee pollen is often referred to as nature's most complete food. Human consumption of bee pollen is praised in the Bible, other religious books, and ancient Chinese and Egyptian texts. Bee pollen rejuvenates your body, stimulates organs and glands, enhances vitality, and brings about a longer life span. Bee pollen's ability to consistently and noticeably increase energy levels makes it a favorite substance among many world class athletes and those interested in sustaining and enhancing quality performance.

Bee Propolis
Bee propolis, often called Nature’s penicillin, has historically been used to treat TB, ulcers, mitosis, colitis and to boost immunity. Bee propolis has been shown to destroy bacteria, viruses, fungus and even penicillin-resistant bacteria (staphylococcus). It contains bioflavonoids, one of which (galangin) is a natural antibiotic. As well, Bee propolis boosts immune functioning, specifically by increasing the activity of phagocytes (killer cells). Bee Propolis also inhibits prostaglandin production, thereby stopping inflammation.

Bee Propolis is a resin collected from plants by bees and used in the construction of hives. Bees adopted sterilization habits long before humans. The most sterile place in nature is the bee hive. Propolis is the natural substance responsible for neutralizing any bacteria, fungi or virus which enters the hive. One of the most powerful foods found in nature, Propolis is a highly complex mixture of waxes, resins, balsams, oils and a small amount of pollen.

Bee Propolis is a waxy substance collected by honey bees which contains phytotonizides. Phytotonizides are believed to contain immunity factors, which when used internally, stimulates the body and gives it a natural resistance to diseases (a natural antibiotic). Propolis is gathered from all around the world, and proper temperature control will assure maximum freshness and consistency.

As a supplement, Bee Propolis is an excellent aid against bacterial infections. Stimulates 'phagocytosis'; helps white blood cells to destroy bacteria. Good results against inflammation of the mucous membranes of the mouth and the throat, dry cough, halitosis, tonsillitis, ulcers, and acne. Stimulates immune system.

Royal Jelly
Royal Jelly is a substance of complex chemical structure produced by the young nurse bees as larva food. Although it is not quite as well known as bee pollen, royal jelly equals pollen in its salutary effects.

The young nurse bees make royal jelly, it is a secretion from glands on the tops of their heads. For 2-3 days, royal jelly is the only food given to all young larvae in their maturation process, while for the queen larvae, it is the specific food for their whole life period. During the 3 days in which the worker bee larvae are fed on royal jelly, they reach the maximum development; their weight multiplies about 250 times. The queen (fed only on royal jelly for her entire life) reaches maturity 5 days earlier than the worker bees; and, when she is fully grown, her weight is double that of the working bee. The span of the worker bee's life is about 35-40 days; while the queen lives 5-6 years and is extremely prolific. She is fertilized once, and from that moment on can lay as many as three thousand eggs a day during the season. As incredible as this may seem, she can lay that many eggs for five years.

This rich concentrated food is not just useful for the bees. It contains remarkable amounts of proteins, lipids, glucides, vitamins, hormones, enzymes, mineral substances, and specific vital factors that act as biocatalysts in cell regeneration processes within the human body.
