- Suggested Use
Vitamin B12 does more than merely prevent anemia. This water-soluble vitamin is necessary for at least eight important areas of whole body health, including: 1) energy production; 2) production of the genetic materials DNA and RNA; 3) nervous system function, as it is needed to produce the protective sheath around nerves; 4) production of a neurotransmitter that helps with memory and learning; 5) brain health, since it may be helpful for some forms of depression; 6) slowing the cognitive decline that comes with aging; 7) the synthesis of red blood cells, and 8) cardiovascular health (B12 works with folic acid to control high homocysteine levels that dramatically increase the risk of heart disease and stroke).
B12 deficiencies and symptoms
Vitamin B12 deficiency is far more widespread than previously recognized, according to research by the US Department of Agriculture (USDA). Because B12 is found primarily in foods of animal origin, vegetarians and vegans are particularly susceptible to B12 deficiencies. Yet, people who eat meat now have B12 deficiency rates equal to vegetarians. B12 levels also decrease as we age. Age-related deficiency is associated with hearing loss, memory impairment, and psychiatric disorders, along with heart disease and stroke. Surprisingly, the USDA study found that adults aged 26 to 49 years now have high rates of B12 deficiency, equal to that of older people.
The classic deficiency symptom is pernicious anemia; however it appears that a deficiency will begin to affect the brain and nervous system first. Impaired nerve function can cause numbness, a pins and needles sensation, or a burning feeling in the feet, as well as imp- aired mental function. Neurological symptoms of B12 deficiency can occur even if your B12 level is well above the currently accepted deficiency level.
Suggested Use: Methylcobalamin, the active form of B12, demonstrates exceptional activity immediately upon absorption, while other forms such as cyanocobalamin must be converted to methylcobalamin in a two-step process. Helps form red blood cells, prevents vitamin B12 deficiency, and helps maintain good health.
Directions (Adults): Dissolve 1 tablet daily under the tongue or as directed by a health care practitioner. For advanced neurological disorders, such as MS, Bell’s palsy, diabetic neuropathy, and Alzheimer’s, take 5,000 mcg daily. Persons with any severe neurological condition should work closely with their health care practitioner. Natural Factors provides B12 Methylcobalamin in 1,000 mcg and 5,000 mcg sublingual tablets. As all the B vitamins work together, it makes sense to take a B-complex daily when taking high amounts of any B vitamin.
Cautions: The minimum daily requirement for vitamin B12 can be exceeded ten thousand-fold with no signs of toxicity. Excesses are excreted in the urine. High doses of methylcobalamin have been used in humans for degenerative neurological disorders, such as Parkinson’s, Alzheimer’s, Bell’s palsy, and multiple sclerosis. People with amyotrophic lateral sclerosis (Lou Gehrig’s disease) took 25 mg (25,000 mcg) a day of methylcobalamin for a month and patients with multiple sclerosis were given 60 mg (60,000 mcg) daily. Pregnancy and lactation: Vitamin B12 supplementation is generally regarded as safe during pregnancy and lactation; however, therapeutic dosages, such as those found in stand-alone vitamins should only be used under the supervision of a health care practitioner - For pregnant women, the appropriate dosage of vitamin B12 is found in specially-designed prenatal vitamins. Children: Although vitamin B12 is considered suitable for children even at the adult dosage, it is preferable that children using high dosages do so under the supervision of a health care practitioner - Multivitamins such as those found in Big Friends or Learning Factors are appropriate for daily maintenance.
Contra-Indications: B12 supplementation can mask a folic acid deficiency; consult a health care practitioner if you are uncertain whether or not you are taking adequate folic acid.
