Additional tests may include full blood count (to check for macrocytic anaemia), methylmalonic acid and homocysteine levels (which rise in B12 deficiency), and tests for intrinsic factor antibodies if pernicious anaemia is suspected
Additionally, B12 can help boost energy levels, improve mood, and enhance cognitive function, all of which are important for maintaining an active and fulfilling lifestyle
A legitimate certificate of analysis should include: HPLC chromatogram with retention time and purity percentage, mass spectrometry confirming the molecular weight near 1815.1 Da, amino acid sequence confirmation, endotoxin level (ideally below 1 EU/mg), and moisture content
I started on B12 injections in March last year, loading doses every other day for two weeks
Vegetarians and Vegans: Since vitamin B12 is primarily found in animal-based foods, individuals who follow vegetarian or vegan diets may not get adequate levels through food alone
