The recommended dietary allowance (RDA) during pregnancy is an increase from 2.0 mcg/day to 2.2 mcg/day to cover fetal storage. The World Health Organization (WHO) advises an increase of 0.4 mcg/day to a total of 1.4 mcg/day. Vitamin B12 metabolism during lactation involves the mechanism of secretion and forms in milk.
If you're pregnant, not having enough vitamin B12 can increase the risk of your baby developing a serious birth defect known as a neural tube defect. The neural tube is a narrow channel that eventually forms the brain and spinal cord.
a short course of oral B12 (e.g. cyanocobalamin 1000microg/day) should be given. Early repeat B12 assay (e.g. 3-4 weeks) is recommended to ensure response. Parenteral therapy with hydroxocobalamin (1000microg/1mL), given by intramuscular injection, once weekly for 3 weeks is commonly used.
And given B12 is required for the production of red blood cells, a deficiency in Vitamin B12 can lead to a deficiency in Iron. This is why the onset of anemia is often the result of a B12 deficiency rather than an Iron deficiency on its own.
The most common way to treat B12 deficiencies is by adjusting your diet. If this is unsuccessful, vitamin supplements may be recommended. If you're looking to boost the amount of vitamin B12 in your diet, you should eat more animal products, like meat, seafood, dairy and eggs.
Use of a vitamin B12 supplement in pregnancy is not expected to cause any problems that require additional monitoring of the baby. Women diagnosed with a vitamin B12 deficiency in early pregnancy may receive more detailed anomaly scans to check for neural tube defects in the baby.
Some sources suggest that full recovery may take between 6 weeks and 3 months.
Bananas are a cheap, healthy, and nutrient-dense fruit that can easily become a part of every individual's diet. It is one of the best fruits rich in vitamin B12.
Greek yogurt is high in vitamin B12.
“Greek yogurt, especially the non-fat variety, is high in vitamin B12, a necessary nutrient for red blood cell formation, the nervous system, and energy production systems,” Schlichter says.
' “A recurring theme in medical literature is that B12 deficiency is a fairly rare cause of miscarriage or stillbirth. The evidence, however, suggests otherwise. One recent study, for instance, compared thirty-six women who'd suffered recurrent foetal loss to forty women who'd carried healthy babies to term.
Your body needs vitamin B-12, also called cobalamin, and folate, also called folic acid, to function normally. Both nutrients play important roles in creating red blood cells and making DNA and RNA to help build cells. B-12 also helps your nervous system function as it should.
Taking folic acid at high doses can hide a vitamin B12 deficiency. So these vitamins are often taken together.
There are certain foods that also need a cut-down in case of vitamin B12 deficiency. “Some foods and drinks can interfere with vitamin B complex intake like alcohol, caffeine and processed foods, etc should be avoided completely,” Shah added.
Stage 1 is decreased levels of vitamin B12 in the blood. Stage 2 is low concentration of vitamin B12 in the cell and metabolic abnormalities. Stage 3 is increased levels of homocysteine and MMA and decreased DNA synthesis resulting in neuropsychiatric symptoms. Stage 4 is macrocytic anemia.
It may take a few weeks before your vitamin B12 levels and symptoms (such as extreme tiredness or lack of energy) start to improve. If you have hydroxocobalamin injections to boost your vitamin B12 levels at the start of treatment, the cyanocobalamin tablets may start to work within a few days.
If you follow a plant-based diet, then vegetables like spinach, beetroot, butternut squash, mushroom and potato contain good amounts of vitamin B12.
Some of the list toppers for cereals with the most vitamin B12 are Kellogg's All-Bran Complete Wheat Flakes, Kellogg's Special K Low Fat Granola, Kellogg's Special K, General Mills Whole Grain Total, General Mills Multi-Grain Cheerios, and Kashi Heart to Heart Oat Flakes.
