The Context First lets set the scene of why and how medicines are classified in the UK and the circumstances in which a change might be made

With vitamin B12 injections, your body only takes what it needs

When you ingest vitamins orally, your body has to process them through the digestive system, which can slow down the absorption rate

The vitamin is absorbed in two ways: Active through a special transport molecule (intrinsic factor) saturated at approximately 1.5g per dose/meal Passive through vitamin B12 that passes through the intestinal wall without a transport molecule maximum 1% of the supplied dosage The real intake is calculated through the combination of these two mechanisms

We will analyse the effect of vitamin B 12 separately in the following subgroups: Vitamin B 12 status: based on cobalamin (cut-off: 150 pmol/L) based on low total homocysteine (cut-off: 10 mol/L) based on low methylmalonic acid (cut-off: 0.26 mol/L) Maternal body mass index (cut-off: 18.5) Vegetarian (yes/no) Birth weight (cut-off: 2500 g) In these subgroup analyses, the differences in the effect between the levels of the subgroups will be measured by including two-way interaction terms in multiple regression models

The injectable formulation is designed to quickly replenish Vitamin B12 levels, essential for nerve function, DNA synthesis, and red blood cell formation
