Mild to moderate deficiencies of vitamin B12 are fairly common, with about 40% of people in Western populations reported to experience them [1]. But whether you suspect that you’re low on B12 or you’re currently in remission from a B12 deficiency, waiting for symptoms to dissipate can feel frustrating. The length and quality of your recovery process depend on the severity of your condition, but it can be immensely helpful to have some more insight into what to expect from the process. Another study has concluded that 1,000 mcg of oral cyanocobalamin each day in the beginning, later on the weekly dose and followed by monthly are equally effective as 1,000 mcg of IM cyanocobalamin.

Note that the percent of vitamin B12 your body can absorb from supplements is not very high — it’s estimated that your body only absorbs 10 mcg of a 500-mcg B12 supplement ( 1). In most cases, a weekly dosage of 1,000 mcg of vitamin B12 is enough. Extremely high doses of vitamin B12 from injectionsYou should not use Vitamin B12 if you are allergic to cyanocobalamin or cobalt, or if you have Leber's disease (an inherited form of vision loss). Cyanocobalamin can lead to optic nerve damage (and possibly blindness) in people with Leber's disease. The estimated bioavailability of vitamin B12 from food varies by vitamin B12 dose because absorption decreases drastically when the capacity of intrinsic factor is exceeded (at 1–2 mcg of vitamin B12) [ 16]. Bioavailability also varies by type of food source. For example, the bioavailability of vitamin B12 appears to be about three times higher in dairy products than in meat, fish, and poultry, and the bioavailability of vitamin B12 from dietary supplements is about 50% higher than that from food sources [ 17-19]. Cyanocobalamin taken by mouth should only be used if your body can properly absorb it. You may need a form of vitamin B12 that is injected or inhaled in the nose if you have any of the following health problems: pernicious anemia, food absorption problems, stomach/intestinal surgery (such as gastric bypass or bowel resection), stomach/intestinal disease (such as Crohn's disease, colitis, diverticulitis, pancreatic insufficiency), irradiation of the small bowel. As a rule of thumb, vitamin B12 blood values below 170–250 pg/mL for adults indicate a vitamin B12 deficiency. Furthermore, homocysteine levels higher than 13 micromol/L or blood values of methylmalonic higher than 0.4 micromol/L might also suggest a vitamin B12 deficiency. [1] How long does it take for vitamin B12 supplements to work? Vitamin B12 naturally occurs in animal products, like meat and dairy, and can also be found in fortified vegan foods like plant milks, faux-meats, breakfast cereals and yeast extracts. Long-term vegans who avoid fortified products are at a particularly high risk of deficiency and should take supplements to make up for this.

Supplements. Even the lowest doses in B12 supplements are many times the recommended dietary allowance. Doses up to 1,000 mcg, though unnecessary, aren't harmful. Finally, evidence pointing to an association between lower vitamin B12 levels and a higher cancer risk includes observational data showing a risk of gastric cancer that was 5.8 times higher in male smokers with lower vitamin B12 levels (less than 394 pg/mL [291 pmol/L]) than in those with levels higher than 591 pg/mL (436 pmol/L) [ 69]. Also, two meta-analyses found associations between lower vitamin B12 concentrations or intakes and a higher risk of colorectal cancer [ 70] and prostate cancer [ 71]. Vitamin B12 is a water-soluble vitamin that is naturally found in animal products. Some fortified foods, dietary supplements, and medications contain a synthetic version of vitamin B12. When you eat meat, fish, eggs, or dairy products, vitamin B12 is released from protein by hydrochloric acid and enzymes in the stomach; synthetic vitamin B12 is already in this released (free) form. Free vitamin B12 then combines with intrinsic factor — a substance secreted by the stomach cells—which enables it to be absorbed from the small intestine. Who needs more B12?If you are taking supplements that you have bought, follow the dosage instructions that come with them. How to take it Most women get the recommended daily amount — 2.4 micrograms (mcg) for most adults, 2.6 mcg for pregnant women, and 2.8 mcg for women who are breastfeeding — in their diets. However, you are at increased risk of vitamin B12 deficiency if any of the following applies: In terms of dosage, most adults require 2.4 mcg of vitamin B12 per day. However, this amount may be slightly higher for certain groups, including people who are pregnant or breastfeeding. Is it OK to take 1000 mcg of B12 a day? swelling (inflammation) in your intestines because of conditions like Crohn’s disease and coeliac disease Another dose-finding trial study shows that the lowest daily dose of oral cyanocobalamin required to normalize the biochemical markers of mild vitamin B12 deficiency varies from 647-1,032 mcg in the elderly.
