Cyanocobalamin is one form of B12 because it can be metabolized in the body to an active coenzyme form. The cyanocobalamin form of B12 does not occur in nature normally, but is a byproduct of the fact that other forms of B12 are avid binders of cyanide (–CN) which they pick up in the process of activated charcoal purification of the vitamin after it is made by bacteria in the commercial process. Since the cyanocobalamin form of B12 is easy to crystallize and is not sensitive to air-oxidation, it is typically used as a form of B12 for food additives and in many common multivitamins. Pure cyanocobalamin possesses the deep pink color associated with most octahedral cobalt(II) complexes and the crystals are well formed and easily grown up to millimeter size.

Like carbohydrates and fat, protein is a “macronutrient,” meaning that you need relatively large amounts of it to stay healthy. (Vitamins and minerals, which you only need in small quantities, are called “micronutrients.”)
Most people can prevent vitamin B12 deficiency by eating enough meat, poultry, seafood, dairy products, and eggs.

Neural tube defects (NTD) may result in anencephaly or spina bifida, which are mostly fatal congenital malformations of the central nervous system. The defects arise from failure of embryonic neural tube to close, which occurs between the 21st and 28th days after conception, a time when many women are unaware of their pregnancy (38). Randomized controlled trials have demonstrated 60% to 100% reductions in NTD cases when women consumed folic acid supplements in addition to a varied diet during the month before and the month after conception. Increasing evidence indicates that the homocysteine-lowering effect of folic acid plays a critical role in reducing the risk of NTD (39). Homocysteine may accumulate in the blood when there is inadequate folate and/or vitamin B12 for effective functioning of the methionine synthase enzyme. Decreased vitamin B12 levels and elevated homocysteine concentrations have been found in the blood and amniotic fluid of pregnant women at high risk of NTD (40). The recent meta-analysis of 12 case-control studies, including 567 mothers with current or prior NTD-affected pregnancy and 1,566 unaffected mothers, showed that low maternal vitamin B12 status was associated with an increased risk of NTD (41). Yet, whether vitamin B12 supplementation may be beneficial in the prevention of NTD has not been evaluated (42).

The second clinical question is whether malabsorptive disease exists. All medically initiated encounters mandate this search. As insensitive as it is, IF antibody is the only credible test available for PA and should be obtained at the outset, with or without serum pepsinogen I or gastrin. If unrevealing, more invasive approaches (eg, gastroscopy, gastric analysis, small bowel testing) can be weighed. If the patient had gastric surgery, FBCM is probable.27,33,39 Direct testing for FBCM is unavailable and surrogate markers are unreliable27,49; the diagnostic sensitivities of gastrin and pepsinogen for FBCM are much lower than for PA (30%-32% vs 90%-92%).

For my OHP in particular, many of the working sets involve the empty bar (45 lbs) which isn’t something I have to “try” on despite my max being low (65 lbs).
