Radioactive vitamin B12 absorption studies: results of direct measurement of radioactivity in the blood. A physiological test dose of 0.46 µg. vitamin B12 labelled with 60Co (0.5 µC.) was given by mouth after an overnight fast and 2 hr. before breakfast... A Doscherholmen,PS Hagen...
Results showed daily high-dose methylcobalamin lozenges are a viable, convenient alternative to B12 shots and are equally effective.Additionally, lozenges offer a significant cost advantage.Effect of Daily High-Dose Methylcobalamin Lozenge Regimen or Weekly Injections in Patients with Cobalamin Deficiency. ...
RESULTS: Paired t-test analysis showed that serum homocysteine concentrations were significantly higher in CAD patients (23.83 +/- 11.29 mumol/L) than in control subjects (19.69 +/- 8.51 mumol/L; p < 0.001). Homocysteine levels were also higher in males than in females. These findings were...
The presence of autoantibodies to intrinsic factor in the test serum does not interfere with charcoal assay, because these antibodies are destroyed when the serum is heated in the boiling water-bath. From equation (5) given earlier, it is clear that B’ can be solved for various anticipated ...
Results The study consisted of 90 adolescences, 45 of whom were in the patient group and 45 of them were in the control group. While the mean age was 14.1 ± 1.71 years in the vitamin B12 deficiency group, it was 14.1 ± 1.62 years in the control group and there was no...
The results of this series of experiments with chicks trained on a single trial, passive avoidance task, demonstrate that methotrexate-induced folate deficiency, and excess levels of folate and B 12 lead to amnesia in these subjects. The amnesia appears only after 50 min following learning, leavin...
The test time is short; no interference peak appears; the theoretical plate number is up to above 2000; the resolution, the tailing factor, and the asymmetry degree all meet the requirements of Chinese pharmacopoeia; and the detection results is good.孙伟东...

humans is vitamin B9(folate)32, which is functionally related to B12(ref.33). However, co-supplementation of B12and B9was indistinguishable from B12alone (Fig.1eand Extended Data Fig.3c,f,g). Collectively, these results demonstrate that vitamin B12is a limiting factor for in vivo ...
(and to prevent one) is to use a sublingual, bio-active B12 supplement, formulated along with co-factors B6 and folate, also in their bio-active forms. Because B12, B6 and Folate play such a vital role in energy production and detoxification, results from one bottle will usually reveal ...
