(Safety Guide) Most metabolic intervention protocols fail because they target only one pathway
Intrinsic factor, a protein that shuttles B12 through the absorption process, becomes saturated after a meal containing an above-average amount of B12 and about 4 to 6 hours are required before it can efficiently absorb another dose (IOM, 1998)
If significant deficiency is confirmed via blood test, a loading dose protocol may be recommended in line with NICE guidance typically more frequent injections over the initial weeks to rapidly restore levels
MIC-B12 has a documented safety profile in the clinical literature, though common side effects, warnings, and contraindications vary by formulation
A revved up metabolism can cause temporary exhaustion
A low reticulocyte count can be a sign of B12 deficiency because the bone marrow cannot make red blood cells without B12
