Vitamin B12 is one of the most important natural elements used by a healthy body. It is essential for the formation of red blood cells, as it helps DNA synthesize in a rapid manner within the cell division process. Vitamin B12 also has a major part in helping the body maintain a functioning nervous system.

How to Naturally Achieve Vitamin B12 Benefits

Vitamin B12 can be found in animal-related products like meat, dairy, and eggs. These are the only sources within the natural world where this B compound can be discovered. Man-made processes have been known to find what are called B12 analogues in algae (Spirulina) and seaweed (nori). However, these analogues are not powerful enough to offer dietary benefits.

To find the best sources of vitamin B12, it is best to discover which foods have the most micrograms per volume. To understand this, you must first know that 1000 micrograms is equal to one milligram of weight. Meat, cheese, eggs, and milk all have different amounts of vitamin B12, depending on their weight and how they are prepared.

Individuals who have diets rich in animal products usually receive all the B12 nutrition they need for their bodies to work properly. However, those who do not partake in meat, dairy, or eggs on a weekly basis often develop deficiency diseases. It is essential for these people to find alternative sources of vitamin B12 to take on a daily basis.

The Body Maximizes the Benefits of Vitamin B12 Too

The human body participates in what is called enterohepatic circulation. Excess vitamin B12 is naturally excreted through the body's bile and re-absorbed back into the tissues. This absorption process adds between one and ten micrograms to one's daily intake each day.

Of course, anyone in the modern world can purchase vitamin B12 supplements to enhance the natural re-absorption and dietary processes. Many commercial foods are also fortified with B12 and are great for those concerned with their vitamin intake. These can include yeast extracts, protein powders, soy milks, vegan cheese, and breakfast cereals.

There is no evidence that excess of B12 has a toxic effect on the body. In order to create a nutritional synergy within the body, vitamin B12 should be taken along with calcium, sodium, iron, potassium, and vitamin C. Alcohol, fermented yogurts, and some medications can interfere with the absorption of B12 in the body as well.

When to Ask about Taking Vitamin B12

Since the benefits of vitamin B12 are so basic for the human body, it is important to know how to recognize B12 deficiency. Signs of this include fatigue, a ringing in the ears, weakness, shortness of breath, and some neurological problems. These in turn include mental changes such as irritability, confusion, and depression as well as nerve damage in one's extremities.

Whey is a by-product of making cheese from cow's milk, which contains two main proteins: casein and whey. When milk is heated, the solid curd (casein) that becomes cheese separates from the watery liquid (whey). When dried and powdered, whey is a good source of protein that supports the immune system and builds muscle.

Whey protein is a mixture of three major proteins: beta-lactoglobulin (65 percent), alpha-lactalbumin (25 percent), serum albumin (eight percent) and several minor proteins such as lactoperoxidases, lysozyme and lactoferrin. It is commonly used as a nutritional supplement by those who wish to increase muscle tissue. Whey protein is also used to restore lost muscle tissue by people who suffer muscle wasting because of disease or medical treatment.

Because it contains many of the same ingredients found in mother's milk, whey is an important ingredient in baby formulas. That said, whey protein powder is not intended for use as an infant formula. As a nutritional supplement for adults, whey protein powder has been popularized by athletes and bodybuilders who use it to repair and build muscle after exercise. Whey protein supplements are commonly mixed with other ingredients and consumed in shake form.

Because whey protein is derived from cow's milk, people with milk allergies or intolerance should exercise caution. However, whey protein isolate may reduce gastrointestinal side effects in people who are lactose intolerant because nearly all of the lactose has been removed during filtration. In any case, checking the ingredients listed on the label before consuming is always a good idea.

Whey Protein Supplements

Not all whey supplements are the same. Many different formulations of whey protein are available, but the two main types are whey protein concentrate and whey protein isolate. Each has a different nutritional profile and cost. Basically, different formulations contain varying levels of whey protein (ranging from 35 percent to 95 percent), fat and milk sugar (lactose).

After whey is separated from the curd, it undergoes a series of processing steps that concentrate the protein and remove the other compounds. First, whey is filtered to remove lactose, minerals, vitamins and fat. More filtration creates a higher concentration of whey protein. When the protein concentration is less than 88 percent, it is considered whey protein concentrate, but when it's greater than 88 percent, it is considered whey protein isolate. After whey is filtered, the protein is pasteurized, excess liquid is evaporated and the protein is dried. Drying occurs at low temperatures to prevent damage to the protein. More processing results in a higher percentage of whey protein and, generally, a more expensive product.

Manufacturers use whey protein concentrate, whey protein isolate or a combination of the two to make different products, such as Designer Whey, 100 Whey and GNC Whey. They also use other methods to enhance whey protein's digestibility and absorbability by the body. Some of these methods include cutting the whey proteins into smaller pieces (hydrolyzation) to enhance absorption, making whey protein powder easier to mix (optimization) and using different types of filters (microfiltration, ultrafiltration and ion exchange) to create various fractions of whey protein subtypes. Again, more processing usually increases cost.

When compared with other proteins, such as egg and soy, whey scores high in three measures. The first is the "Protein Digestibility Corrected Amino Acid Score", which measures how easily a protein is digested. The maximum value allowed by USDA is 1.0, and whey protein scores 1.14. The second is "Biological Value", which measures protein quality. Whey scores 100 out of 100, beating many other types of protein, including soy. The third is the "Protein Efficiency Ratio", which measures how much absorbed protein is retained. Whey scores 3.2 out of 4.0. Egg scores higher at 3.9.

Whey protein also differs from other proteins in its ability to stimulate the immune system. Several studies have been done on people with cancer and HIV. Whey protein appears to enhance the body's natural ability to fight infections.

A healthy diet can be made even healthier by taking dietary supplements. Have you ever read the nutrition information on a bottle of vitamin pills? Your body requires an astounding number of vitamins and minerals each day. Eating healthy foods alone rarely gives your body all the nutrients it needs, especially if you schedule exercise into your daily routine.

Dietary supplements ensure that your body has everything it needs and then some. How many people know exactly which foods provide the hundreds of minerals and vitamins your body requires? Not many. Dietary supplements are not a replacement for a healthy diet, but taking them does guarantee that your body has everything it needs.

Combating Free-Radicals with Dietary Supplements

Free-radicals are the byproduct of oxygen and exercise, and they actually damage bones and muscles. Isn't it terrible to think that your exercise program can actually be hindered by oxygen? Don't stop breathing during exercise. Make sure your body has plenty of antioxidants.

Antioxidants negate free-radicals before any damage is done. Green Tea and large portions of fruits and vegetables contain antioxidants, and you can also get antioxidants from dietary supplements. Vitamins A, C, and E are all excellent antioxidants.

Body building supplements expedite and augment the physical, mental, and social benefits derived from regular exercise and a healthy diet. Reports indicate that people who exercise regularly to develop and maintain a muscular and well-sculpted body feel more confident than those who do not. Body image is important to most people. Whether you want muscles that are long and lean or bulging and defined, the best way to attain the body of your dreams is by taking body building supplements to complement a weight training program.

Most people begin a workout program hoping to improve their bodies. Few, however, know how to achieve this goal. It is very common for a beginner to quit a training program because the body he or she sees in the mirror does not reflect the blood, sweat, and tears sacrificed at the gym. Without a proper diet and the help of body building supplements, it can take several months before even the most rigorous workout program yields the kind of results people notice.

Even people who are persistent in lifting weights and training their cardiovascular systems often cannot reach their goals. Athletes and body builders hit what is called a plateau, a level at which improvement is impossible. However, using body building supplements can help meet or exceed even the most lofty training goals.

Body building supplements are a tried and true way of building a better body. Athletes and body builders have been using supplements for centuries. Weight gainers are still popular and still work, but now the industry offers more advanced and effective formulas.

Modern medical science has given millions the opportunity to shape their bodies the way they want them to look. Creatine, amino acids, and fat burners are a few examples of products that speed up the process of developing muscle and definition. Professional athletes are stronger and faster than ever, even in sports that have strict steroid testing policies. One of the biggest reasons for this is the widespread use of safe and legal supplements.

The proliferation of the use of fish oil as a cardiac function enhancer has brought to light how easy it is to reduce the risk of either a debilitating or fatal heart attack. Not only is fish an excellent source of protein, it is lower in high saturated fat than other meat products. Fatty fish like herring, sardines, mackerel, salmon, and albacore tuna are high in omega-3 fatty acids. Frequent fish consumption or a supplement of fish oils has been shown to significantly reduce the risk of coronary heart disease.

Not only has the use of the oil from fish been effective in treating heart patients, but it has also shown promise of much improvement in the mental status of depressed patients. There are clinical trials underway that are showing the oil in fatty fish is significant as a treatment for attention deficit disorder and schizophrenia as well. Fish oils have also been effective in reducing inflammation in people suffering from rheumatoid arthritis and ulcerative colitis.

Fish Oil Is Very Beneficial

It is very important that the processing and packaging of the oil from fish is done in such a way that the integrity of the oil is maintained. Stability is crucial to top quality oil. Unstable oil may contain significant amounts of mercury, pesticides, and undesirable oxidation products. To insure high quality oil and stability, adequate amounts of vitamin E are used and it is packaged in light and oxygen resistant packages such as foil pouches.

Testosterone is a significant male hormone, responsible for producing and maintaining what is considered normal male characteristics. Beginning from puberty, testosterone stimulates physical changes such as the growth of facial and pubic hair, the lowering of the voice, the growth of the penis and the testes, increase in muscle mass and strength, and growth in height. Continuing through adulthood, testosterone maintains the sex drive, sperm production, bone mass, muscle mass, hair patterns, and many other important functions within the male body.

The body produces testosterone through the use of chemical signals sent to two primary locations in the body--the hypothalamus and the pituitary gland. The pituitary, located at the base of the brain, produces the hormone, while the hypothalamus controls the amount that is produced. In this finely balanced system, the brain senses the need for either more or less testosterone. If the levels of testosterone become low, the brain signals the pituitary gland to secrete a follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The LH signals the testes to produce more testosterone. If the levels of testosterone become too high, the brain signals the pituitary to make less LH, thereby slowing the production of the hormone.

In the past, hormone therapy research and medicine was staunchly based within the realm of women's health, specifically in the study of menopause. This is no longer the case. In recent years many advancements have been made in the research of low testosterone and its repercussions on the male health system. Today leading researchers in the study of low testosterone perceive that between 20 and 50 percent of healthy men between the ages of 50 and 70 years suffer from low testosterone levels.

Male Menopause: Fact or Fiction?

The term given to define this phenomenon is andropause, at times considered to be the "male menopause". This is a bit misleading, as there are definitive differences between menopause and andropause, such as the rate at which the symptoms appear. Menopause is a change in the female body, clearly marked by the discontinuation of the menses, or period. Andropause occurs over a much longer duration, and there is not one major symptom to point out its existence. It is clear that both menopause and andropause occur naturally in the life cycles of men and women, usually beginning sometime during the fourth and fifth decades of life. During the onset of andropause, the testosterone levels will drop below what is considered normal.

Although there is not a specific symptom signifying the onset of andropause, there are several clues to look for. As the testosterone levels fall, the mass and strength of muscle decreases, signs of osteoporosis may set in, erectile dysfunction and/or decreasing sex drive is plausible, increased body fat, memory loss, difficulty sleeping, and possible mood swings can also surface.

The evidence of how low testosterone levels can effect the male health system has led medical researchers to surmise that this syndrome has gone misdiagnosed for far too long. It is estimated that as many as five percent of all males may be at risk for low testosterone. As this is a fairly new field of research, it is probable that the actual numbers are higher.

Other studies into the effects of low testosterone are finding connections between the levels of testosterone and risk of heart disease. Men found with higher levels of testosterone are showing lower levels in blood insulin counts. This is recognized as vital for the prevention to heart disease and heart attacks.

It is estimated that 4.5 million American men are at risk from low testosterone levels. Research is also showing that the majority of those at risk do not understand how low testosterone can adversely affect their overall health. Today there are several options to reverse the effects of low testosterone levels, increasing one's chances of a longer, healthier life.
