5c-naturalfactors-b12-methyl-engEvery cell in your body uses vitamin B12. Are you getting enough for your brain, heart, nerves, and metabolism?

Could that health problem be a result of Vitamin B12 deficiency?

Every cell in our bodies uses vitamin B12. This nutrient is involved in so many biochemical actions and reactions in the body that it is difficult to list all of its health benefits.
Lately vitamin B12 is getting a lot of attention in scientific circles and among consumers. This is partly due to research showing a connection between B12 deficiency and the advance of hearing difficulties, memory loss and impaired mental function in older adults. It has also been discovered that low levels of B12 can cause a person to exhibit symptoms that mimic those of several serious diseases. Ensuring adequate intake of B12 could prevent mis-diagnosis and inappropriate treatment in such cases.

Doctors may miss identifying a B12 deficiency as a probable cause for symptoms, partly because the common blood serum test apparently measures “human-inactive B12”, which does little or nothing for your cells, as well as active B12. Such a test could hide an actual B12 deficiency.

Some health professionals estimate that up to 80 percent of North Americans are deficient in this crucial nutrient. Symptoms of B12 deficiency include fatigue, anxiety, and anemia, but other non-optimum conditions may be related to lack of this nutrient as well. A sublingual methylcobalamin form of B12, now available from Natural Factors in a 1000 mcg -tablet, is a convenient way of getting enough B12 for better health.
What it does

Vitamin B12 supports nerves, energy and red blood cell production. It is essential for fat and carbohydrate metabolism, and protein synthesis. With other B vitamins (folic acid, and B6) it can reduce levels of homocysteine, a risk factor for cardiovascular disease. B12 is used to treat pernicious anemia and is part of the coenzyme that builds new cells, maintains nerve cells, and breaks down amino acids and fatty acids.

Our ability to absorb naturally occurring B12 from our food decreases with age. Common medications can also deplete B12. These factors make supplementation with a quality B12 a good investment.

Meat Eaters need B12 too
Except for chlorella, plant foods are poor sources of human-active B12. Although vegetarians and vegans are more prone to B12 deficiency, it also occurs among meat eaters. B12 found in meat, eggs, and dairy cannot be efficiently absorbed and used by the body unless one has adequate levels of “intrinsic factor”in the small intestines. The intrinsic factor is a special protein that is key to extracting B12 from foods and assimilating it into the blood. Anyone with poor digestion or who has had stomach surgery should consider supplementing with B12 to ensure adequate levels of this important nutrient.

How to get enough
The sublingual methylcobalamin form of B12, is available from Natural Factors in 1000 mcg tablets, a convenient and tasty way to get enough B12. The 1000 mcg tablets dissolve under the tongue to provide a highly bioavailable form of B12 that is absorbed directly into the bloodstream.

Anyone can support optimum fat and carbohydrate metabolism, brain and heart function, and nervous system health by getting adequate levels of B12 every day.
