It serves as a vital reagent for scientific investigations requiring precise modulation of cellular enzymatic activity without off-target binding
The deficiency can arise due to improper diet or the inability to absorb the vitamin through natural means
Under the Human Medicines Regulations 2012, the supply and advertising of unlicensed medicines for human use is restricted in the UK
Most vitamin B-12 we consume comes from animal meat
