Most people in the United States consume adequate amounts of vitamin B12. Average daily intakes of vitamin B12 from diet are close to 6 mcg for adult men and 3.8 mcg for women. Is vitamin B12 deficiency common? So, it’s pretty safe to take a daily vitamin B12 dosage of 1,000 mcg from supplements, though unnecessary. The body excretes most excess vitamin B12. It has been proved that 69% of 1,000 mcg IM cyanocobalamin has been recovered in the urine after 72 hours, whereas only 27% is found from the same dose of hydroxocobalamin IM injection. As you age, your body naturally makes less stomach acid and intrinsic factor — both of which can affect the absorption of vitamin B12. Presented as sublingual nuggets (that melt under the tongue), this product is a convenient, easy to take version of this versatile nutrient, particularly important for those with a restrictive diet (such as vegan). Beyond energy Vitamin B12 has several health benefits supporting general vitality and wellbeing.

Because the body stores about 1 to 5 mg vitamin B12 (or about 1,000 to 2,000 times as much as the amount typically consumed in a day), the symptoms of vitamin B12 deficiency can take several years to appear [ 7, 33].

It plays a crucial role both in muscle gain and endurance performance. Adverse effects of vitamin B12 deficiency Adequate Intake (AI): Intake at this level is assumed to ensure nutritional adequacy; established when evidence is insufficient to develop an RDA

However, you may want to take more or less, depending on your age, lifestyle, and specific situation. Recommended Dietary Allowance (RDA): Average daily level of intake sufficient to meet the nutrient requirements of nearly all (97%–98%) healthy individuals; often used to plan nutritionally adequate diets for individuals Additionally, there is currently no evidence that one form of vitamin B12 supplement, such as capsule or liquid, is better absorbed than another. Vitamin B12 type: While it has been proposed that methylcobalamin, the active form of vitamin B12, is more readily absorbed than synthetic forms, research has not shown a significant difference.

Limited clinical trial evidence supports the finding that higher vitamin B12 intakes might increase cancer risk. In an analysis of data on 2,524 participants in the B Vitamins for the Prevention of Osteoporotic Fractures trial who were treated with supplements containing 400 mcg/day folic acid and 500 mcg/day vitamin B12 for 2 to 3 years, the risk of colorectal cancer was significantly higher, at 3.4%, in the supplementation group than in the placebo group, whose rate was 2% [ 61]. However, high folic acid levels are potentially linked to increased risk of colorectal cancer, so the result might be due to the folic acid rather than the vitamin B12 [ 62]. Furthermore, the supplements had no significant effect on overall cancer risk.A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/ tongue/throat), severe dizziness, trouble breathing. Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). However, 1000 mcg daily dosing of cyanocobalamin was able to normalize the MMA concentrations in patients with pernicious anemia.

There is no need to take vitamin B12 supplements every day. You can take high dosages of vitamin B12 from supplements once a week. As the biological half-life of vitamin B12 in the plasma is about 6 days, you could take 1,000 mcg of vitamin B12 once a week with the same health benefits. [ 3]Exclusively breastfed infants of women who consume no animal products might have very limited reserves of vitamin B12 and can develop vitamin B12 deficiency, sometimes very early in life [ 56]. The infant’s deficiency can be severe, especially if the mother’s deficiency is severe or caused by pernicious anemia; sometimes, the mother’s own deficiency is clinically mild and not recognized. Undetected and untreated vitamin B12 deficiency in infants can result in neurological damage, failure to thrive, developmental delays, and anemia [ 2, 56, 57]. The reasons include the small amounts of vitamin B12 in the breast milk of vegan mothers as well as the limited amounts of vitamin B12 crossing the placenta in these women during fetal development.
