Vitamins And Minerals For The Eyes

Vitamins And Minerals For The Eyes

Vision is one of our most precious senses. One of the things that we can do daily to protect our eyes from harm is to be sure that each day we consume the recommended daily intake levels of vitamins, minerals and other nutrients.

As with everything about our bodies, proper nutrition plays an invaluable role in keeping our eyes functioning as well as possible. There are certain nutrients that are known to be especially associated with ocular health.

Among these are the anti-oxidant vitamins. The eye, especially the lens and the retina, is particularly vulnerable to the effects of unchecked free radicals, which are a byproduct of oxygen, cellular processes and environmental contaminants. Anti-oxidant vitamins help to combat free radicals.

The primary anti-oxidant vitamins include Vitamin A, Vitamin C, and Vitamin E. in addition to their important action against free radicals, they promote healthy cells and tissues in the eye. Lutein and Zeaxanthin are two more valuable anti-oxidants that recent research has found to be especially effective in maintaining the health of the eyes.

In addition to the vitamins that promote ocular health, there are several minerals that have been determined to play a significant role in the health of the eye. Among these are zinc, selenium, manganese, and copper. Zinc is an important mineral that serves to regulate sight, smell and taste and the concentration of zinc in the eye is higher than any other part of the body.

One important function of zinc in relation to the eyes is its role in the regulation of the amount of Vitamin A, essential to eye health, from the liver. People who have a deficiency in selenium have been clinically shown to be more likely to suffer from cataracts.

Recent research into the influence of vitamins, minerals and other nutrients upon the health of the eye has turned up a good deal new information. This has led to the development of specialized dietary supplements designed specifically to promote ocular health. The early results of clinical trials concerning the halting and even reversal of macular degeneration and other age-related eye diseases via specialized nutritional treatments look very promising and research continues at a rapid pace.

Those seeking to benefit from dietary supplements designed to promote ocular health and healing should familiarize themselves with the most common vitamins and minerals in these supplements, doing the research to find out what both the optimum and the safest levels of these nutrients are. Consulting an eye care professional and a licensed nutritionist can be very helpful in planning the best dietary supplement regimen suited to individual dietary needs and health goals.

Making sure that you are achieving the recommended daily intake levels of vitamins, minerals and other nutrients is one of the best things you can do for all over health and well being. In terms of eye health, paying close attention to you daily nutrition can make a real difference in the quality of your vision and help to keep your eyes healthy and functioning well for a good, long time. When properly taken, dietary supplements can be a valuable part of any ocular health focused program.

Vitamin B5 Serves Many Important Functions To Keep Body And Mind

Vitamin B5 Serves Many Important Functions To Keep Body And Mind

Vitamin B5, also known as pantothenic acid, serves the body in many ways. It is a member of the nutritionally elite group of eight vitamins known collectively as the Vitamin B complex. This powerful group of vitamins has a role nearly every major body system and process. The Vitamin B complex serves to keep both body and mind functioning and in good health.

Vitamin B5, like all of the vitamins that form the B complex, is essential to the body’s ability to use the food it takes in as fuel for its myriad of processes, great and small. It works in the regular maintenance and repair of all bodily tissues, from the cellular level up. This makes it an essential part of the body’s efforts to fight the physical damage that excessive stress contributes to.

Vitamin B5 serves many important functions in the nervous system, especially in terms of nerve function and health. Among the contributions that Vitamin B5 makes to the nervous system is the production of neurotransmitters, which are important to the ability of the nerves to communicate.

Because of its important role in the growth and health of the hair and necessity to healthy skin, it is used frequently in a variety of cosmetic products. Vitamin B5, acting as a cofactor to other members of the Vitamin B complex and other nutrients, has an important role in the functioning of the adrenal glands and also serves to promote normal growth of the body, due to its role in hormone production throughout the body.

Deficiency in Vitamin B5 can have a variety of negative consequences for the body and the mind. Physical symptoms include fatigue, headache, nausea, vomiting, dizziness, weakened immune system, abdominal pain, neurological disorders, muscle weakness and cramps, increased insulin sensitivity, acne, digestive problems, and slow or retarded growth.

Mental symptoms of Vitamin B5 include depression, personality disorders and change, sleep disturbances, and insomnia, which generally makes most other deficiency symptoms feel much worse. In general, adults should have about 5mg of Vitamin B5 per day, with women increasing their daily intake to 6mg to 7mg while pregnant or breastfeeding. Children, depending on size and weight, should have about 2mg to 4mg of Vitamin B5 each day.

The importance of the Vitamin B complex to physical health and mental functioning cannot be overstated. For optimum performance of the body and the mind, including cognitive functions and emotional responses and stability, the standard recommended daily intake levels of these vitamins should be achieved every day. Because these are water-soluble vitamins, they are washed away daily with the urine and thus, the body’s supply of these essential nutrients must be renewed daily.

Nutritional supplements are a reliable and safe way to meet these important nutritional goals, provided that attention is given to the accepted limits of dosage. Too much of any nutrient can be toxic, and often can cause as much damage as having too little. The body is a delicately balanced system, and requires that balance to be maintained to function at its best.

Vitamin B1 In The Body And The Brain

Vitamin B1 In The Body And The Brain

Vitamin B1, also called thiamine, is one of the eight vitamins that make up the powerful Vitamin B complex. Like all of the B vitamins, this nutrient plays a great role in the health of the body and the health of the mind. Care should be taken to maintain the recommended daily intake levels of this essential nutrient, as the results of deficiencies can be devastating in nature.

Vitamin B1 serves many purposes in the body. It is an essential part of converting carbohydrates to energy, and necessary to the proper functioning of the nervous system, the heart and the musculature system of the body. Thiamine is very important to the brain, particularly in terms of emotional health and well being, as well as being useful for focus and concentration.

There are a variety of physical conditions and diseases associated with deficiencies in Vitamin B1. Symptoms include pain, numbness and tingling in the extremities, muscle weakness and a lack of physical coordination, particularly in the larger muscle masses that make up the leg muscles.

A deficiency in thiamine can cause enlargement of the heart, which can itself lead to congestive heart failure, and lung congestion. A severe deficiency in Vitamin B1 can lead to nerve damage, brain damage and even death. Mental symptoms associated with a serious lack of Vitamin B include fatigue, psychosis, and confusion.

These are a few serious diseases specifically associated with a deficiency of Vitamin B1, including the notorious beriberi disease. There are also two specific types of brain damage associated with severely low levels of Vitamin B1. One, Korsakoff syndrome, results in confusion and short term memory loss. Another, Wernicke’s Disease has symptoms that include vision disturbances and irregularities, an unsteady walk, and mental confusion.

Despite the obvious importance of Vitamin B1 to many of the body’s important functions, a great deal of people regularly fail to meet the recommended daily intake levels. Alcoholics are particularly vulnerable to being deficient in Vitamin B1, because alcohol ruins the B vitamins.

Illnesses that force bodily fluids from the body, such as chronic diarrhea, can deplete the body’s levels of thiamine, because it is a water-soluble vitamin and the body needs to have its supply renewed every day. There are also rare conditions that interfere with the body’s ability to use Vitamin B1 properly.

Dietary supplements are an affordable, safe and effective way to consistently meet the recommended daily intake levels of Vitamin B1. It is especially important, however, when taking supplements to use them with care and attention, because taking too much Vitamin B1 can cause adverse side effects and even serious health problems.

As with all substances, there is such a thing as too much of a good thing. While there are certain health situations that do call for higher than average doses of this powerful B vitamin, high dosages should only be taken while under the direct care of a qualified health care professional. Like any other medication or dietary supplement, Vitamin B1 supplements should always be kept well out of the reach of children.

Be Sure To Get Your Calcium

Be Sure To Get Your Calcium

We’ve heard it from the days of childhood – calcium is good for the teeth and bones. While it is true that calcium is absolutely necessary to the health and strength of bones and teeth, this essential mineral also serves several other important purposes in the body. Yet, many people routinely fail to consume enough calcium in their daily diets.

In addition to the benefits to teeth and bones, calcium plays a role in helping the blood to clot when it needs to, helping the nerves and muscles to perform their tasks, and the maintenance of cell membranes. It is also important to the prevention of debilitating bone diseases, such as osteoporosis.

Despite the importance of consuming adequate amounts of calcium daily, some studies have found that as much as 75% of people in the United States do not have a sufficient daily intake of calcium. Those following strict vegetarian diets, especially vegan, must be particularly careful concerning calcium intake levels.

Fortunately, there are several varieties of calcium supplements on the market. Adults need between 1000 mgs and 1300 mgs of calcium per day, and should not supplement beyond 2500 mgs, as that can cause other health problems. Your health care professional can help you to choose the amount that you need daily, as preexisting conditions, such as bone loss or damage due to previous deficiencies, can make a difference in how much you should be taking daily.

Some types of calcium supplements are absorbed more easily by the body than others. However, some may be preferable for other reasons. The most common calcium supplements include calcium citrate, calcium carbonate, oyster shell or bone meal based calcium supplements, coral calcium, and calcium gluconate and calcium lactate based supplements.

In choosing your supplement, you should be aware of how to read the label to ensure that you are getting the amount of calcium that you think you are. Elemental calcium is the term used for the calcium that your body will be able to absorb. Some supplements have this and other types of calcium, but it is only the elemental calcium that can count towards your daily intake. Calcium is absorbed best in acidic circumstances, which is why many supplements are recommended for use after meals, when the stomach acids are at higher levels.

Current research has found that calcium citrate is the most efficient of the supplements, meaning that the body absorbs it easily. However, although it is absorbed easier and can be taken at any time of day, whether or not there is food in the stomach, this type often contains less of the elemental calcium, and thus more pills daily will be needed. Calcium carbonate is the most common over the counter calcium supplement and should be taken after meals, because of the increased stomach acid. These, however, should be watched for sodium content.

Calcium is essential for good health and supplements are an excellent way to ensure that you are not among the many people who regularly do not consume the amount of calcium needed daily. There are a variety of factors to be taken into account when choosing a calcium supplement. A little research and consultation with a nutritional specialist can help you to choose the best calcium supplement for your individual needs.

Make Sure That Your Body Is Able To Support The Healing Process

Make Sure That Your Body Is Able To Support The Healing Process

Vitamins, minerals and other nutrients, aside from keeping the internal processes of the body healthy, strong and functioning well, also serve to promote the healing of wounds, both on the external and inner surfaces of the body. The rate at which wounds heal and the quality of the repair tissues depends upon adequate nutrition. There are several vitamins, minerals and other nutrients that affect the healing process.

Vitamin K is essential to the very first step of healing a wound – stopping the bleeding, via the clotting of the blood. Without Vitamin K, healing would not proceed, as the blood would not clot. Vitamin K partners with the mineral calcium in the production of the body’s primary clotting agent, thrombin.

One of the most important vitamins involved in the healing of wounds is Vitamin C. It is particularly helpful in the growth and development of new tissues, in part because it also supports the health and function of the body’s many tiny capillaries that are responsible for taking oxygen and nutrients to the far reaches of the body.

Another aspect of its importance in the growth and development of new tissues, thus in wound healing, as well as the maintenance of existing tissues, has to do with its role in collagen production. Collagen is what makes the scar that holds a wound together and makes up the connective tissue of the body. Collagen supports the structure of the skin. Vitamin C is essential to the production of collagen, meaning that Vitamin C has a great part in literally holding the body together.

Zinc is another mineral important to wound healing. There are more than 300 enzymes in the body that require zinc to perform their tasks. Many of these enzymes relate directly to the healing of wounds, such as the production of collagen. Zinc plays a role in the body being able to make use of certain proteins and in cell division.

However, it should be noted, too much zinc can interfere with the healing of wounds. That is because the body operates on a chemical system that has a delicate balance, and too much zinc interferes with how the body uses copper and other substances, thus throwing off the balance that is necessary for the best wound healing.

Copper, a mineral, is also significant to the process of healing wounds. Copper has many roles in the body, including being a component of numerous enzymes. In terms of healing, one of its most important roles is in the formation of collagen, which is essential to the wound healing process.

The vitamins, minerals and other nutrients that we consume daily are what support all of the processes of the body and the mind. The healing of wounds is essential to the body, and proper nutrition is what allows the process of wound healing to operate at peak performance, meaning that wounds heal as well and as quickly as they should. Dietary supplements are an affordable, safe and convenient way to make sure that your body is able to support the healing process.

Vitamin E Has An Important Role

Vitamin E Has An Important Role

Vitamin E has long been known to have an important role in the all over health of the body. Some studies have associated sufficient intake levels with the prevention of many serious health problems, and research still continues to delve into the many effects of this important nutrient.

One thing that researchers do know for sure, according to recent studies published by the United States Department of Agriculture, most people do not consume the daily requirement of this important vitamin.

Vitamin E protects Vitamin A in the body, allowing it to perform its essential functions. Furthermore, Vitamin E is also one of the anti-oxidants that serve to protect the cells of the body from the damaging free radicals, which are waste products from the making of energy.

Uncontrolled free radicals are thought to contribute to a variety of serious diseases, such as cardiovascular disease and some cancers. Vitamin E is also thought to have a role in DNA repair and in the body’s natural immune system.

It is important to note here that vitamins, minerals and other nutrients play important roles in the body at the correct levels of intake, meaning that more is not always better. Mega-dosing is something that should always be discussed with a physician, not a salesperson.

Supplements can play a vital role in making sure that the body receives the nutrients it needs to be healthy and strong, as well as in the protection of the body from the numerous diseases and health problems associated with the failure to consume the proper daily intake levels of important vitamins and minerals. But, like any other medicine, using supplements inappropriately can be dangerous.

As many people pay attention to reducing fats in their diets, they may unwittingly be reducing their daily intake of Vitamin E, as Vitamin E is found in vegetable oils and nuts, as it is in dark, leafy green vegetables. Maintaining optimum levels of health means that we must be honest with ourselves.

We know that there are certain foods we should eat – such as fresh vegetables and fruits. But, often we do not, pressed by time or simple through a lack of desire, many of us simply do not consume near enough of these important foods. In these circumstances, supplements may be the best choice to ensure that the body gets what it needs to be strong and healthy.

There are many types of supplements on the market. Understanding what you are looking for will help you to make the best decision about which supplement is best for your individual dietary needs.

Vitamin E supplements primarily come in two general types, natural and pharmaceutical. The natural is usually listed on the label as alpha-tocopheryl acetate D-form, while the man-made type is listed as D,L. The man-made version is half as effective as the natural compound.

Dietary supplements are powerful agents, valuable tools in guarding the health of the body and can offer significant protection against illness and disease. These powerful tools should be used with care and attention. Supplementing the diet with Vitamin E can play an important role in your daily health routine, when used correctly, at the levels most suited to your individual dietary and health needs.

The Antioxidant Minerals

The Antioxidant Minerals

Because the antioxidant vitamins tend to get most of the press and publicity, many people are unaware that there are also important antioxidant minerals that are essential to the body’s continuous battle against free radicals and the damage they do. Making sure that the proper nutrients are consumed daily is a necessary part of helping the body to be able to keep free radical damage as low as possible.

A mineral, vitamin or other nutrient is deemed antioxidant if it, on its own or as an essential part of a group of substances, it serves to bring free radicals under control. Free radicals are unstable molecules that generally come from both environmental contaminants and some of the body’s natural processes. There are certain minerals that are an integral part of managing the free radical population within the body.

Selenium has come to be recognized as one of the most important of these minerals, though each does play an important role in free radical management. Selenium is an essential component of the antioxidant enzyme glutathione peroxidase, and this substance is one that is able to stabilize the free radical.

Since the universal acceptance of the mineral selenium, a trace element, as an essential nutrient during the 1950’s, researchers have been studying the ways that it affects health. In 1973, researchers confirmed the antioxidant properties of the mineral selenium, and since then, numerous studies have demonstrated that it may play a significant role in the prevention of certain types of cancers.

However, it should be noted that excessively high levels of selenium can cause serious health problems – as can deficiencies of selenium – and some studies have found excessively high levels of selenium to be associated with other types of cancer. The body is a delicate balance of a variety of chemicals and substances, and optimum performance requires thought and planning.

The minerals zinc and copper form part of another of the body’s important antioxidant enzymes. This enzyme, called superoxide dismutase, is present in the body in two forms. The first form is found almost everywhere in the body, and it needs zinc and copper to function.

The second form of this important antioxidant enzyme, superoxide dismutase is found specifically in the mitochondria, which is the part of the cell responsible for changing the energy that comes from the various nutrients into a form that can be used by the cells. In this second form of the enzyme superoxide dismutase, it is the mineral zinc and the mineral manganese that are essential to the antioxidant enzyme’s ability to function properly.

Making sure that the body has all of the minerals, vitamins and other nutrients it needs each day is very important for both day-to-day and long-term health and well-being. Dietary supplements are a safe and effective means of seeing that the body does have all of the nutrients it needs for all of its systems to work at peak performance levels, especially those that maintain daily health and those that protect health over the long-term. However, nutritional supplements are powerful agents, and must be used within the established dosage guidelines to be beneficial to the health. Used in this fashion, dietary supplements can serve as a valuable part of any health routine.
