How to improve vitamin b12 deficiency

Vitamin B 12 deficiency is a common cause of megaloblastic anemia, various neuropsychiatric symptoms, and other clinical manifestations. Screening average-risk adults for vitamin B 12 deficiency is not recommended. Screening may be warranted in patients with one or more risk factors, such as gastric or small intestine resections, inflammatory bowel disease, use of metformin for more than four months, use of proton pump inhibitors or histamine H 2 blockers for more than 12 months, vegans or strict vegetarians, and adults older than 75 years. Initial laboratory assessment should include a complete blood count and serum vitamin B 12 level. Measurement of serum methylmalonic acid should be used to confirm deficiency in asymptomatic high-risk patients with low-normal levels of vitamin B 12. Oral administration of high-dose vitamin B 12 (1 to 2 mg daily) is as effective as intramuscular administration for correcting anemia and neurologic symptoms. Intramuscular therapy leads to more rapid improvement and should be considered in patients with severe deficiency or severe neurologic symptoms. Absorption rates improve with supplementation; therefore, patients older than 50 years and vegans or strict vegetarians should consume foods fortified with vitamin B 12 or take vitamin B 12 supplements. Patients who have had bariatric surgery should receive 1 mg of oral vitamin B 12 per day indefinitely. Use of vitamin B 12 in patients with elevated serum homocysteine levels and cardiovascular...

• • • • • Vitamin B12 is a nutrient that most people don’t give a second thought to. We put it on the back burner for things like vitamin D, vitamin C, omega-3s, and more, but getting enough of this vitamin is key for optimal human performance. It plays a major role in red blood cell health and formation and nervous system function, and low levels can spell big trouble. But if you’ve been diagnosed with a vitamin B12 deficiency and have started on supplementation, you’re probably wondering how long does it take to work? We’re walking you through everything you need to know about Why Vitamin B12 Is Important Vitamin B12, or cobalamin, is a water-soluble vitamin that plays an important role in overall health and well-being. While its best-known role is in erythropoiesis (red blood cell formation), it’s also involved in: • DNA synthesis • Regeneration of bone marrow, GI lining, and respiratory tract lining • Nervous system development and maintenance • Prevention of anemia Although a B12 deficiency isn’t as common as vitamin D or even folate, it happens. It’s estimated that up to 15% of people over 60 have low levels of vitamin B12 1. But for young people, you’re not excluded from the statistics, as dietary restrictions or underlying health conditions can influence levels. One of the other major roles B12 is involved in is the conversion of homocysteine to methionine. Upon conversion, methionine is activated into S‐adenosyl‐methionine, which plays a vital role in the nervous ...
