Vitamin B12 Injections:
Vitamin B12 (cobalamin) is an essential water-soluble vitamin that the body uses to maintain healthy nerve cells, produce RNA, DNA, and red blood cells, and help iron to function properly. B12 also works with folate to produce the amino acid SAMe which controls mood and supports immune function. B12 injections have many benefits, and are often prescribed for deficiencies that cause fatigue, shortness of breath, diarrhea, numbness and neurological damage.
Absorption and Availability
A vitamin B12 deficiency can result from a lack of intrinsic factor, a substance needed to absorb B12. Almost all patients on acid blockers have difficulty absorbing B12, and many people over the age of 50 also have declining ability to absorb it. One of the benefits of B12 injections over oral supplements is its immediate availability to the body. Injections that go directly into the bloodstream bypass absorption barriers according to the National Institutes of Health (NIH) and can help people with malabsorption issues like those who have intestinal disorders or have undergone intestinal surgeries. Also, vegetarians are often deficient in vitamin B12 and patients with common methylation genetic mutations such as MTHFR may need extra B12.
Vitamin D Injections:
Vitamin D is collected mainly through the skin’s exposure to sunlight. Minimal levels can come from eating animal products. The darker one’s skin is, the harder it is to get adequate levels of Vitamin D from the sun. Almost all children and adults in this country are deficient in this critical nutrient. It regulates the activity of other cells in the body, helps the immune system prevent infections like colds and flus, helps prevent many kinds of cancer, maintains strong bones, and develops the nervous system. A deficiency of vitamin D has been attributed to a wide range of ailments such as hypertension, heart disease, chronic pain, depression, and even autism. Most people are drastically underdosing themselves on vitamin D, to the detriment of their health. An injection is a great way to bring your level up in a hurry.
