Stomach acid tends to decrease with age, which makes it harder to extract B12 from food

First, that individual differences in DNA sequence in genes for intrinsic factor, the intestinal receptor complex, the circulating carrier proteins, the cellular uptake receptor, and the intracellular processing enzymes measurably alter circulating B12 and its active fraction

It usually happens immediately after and in lesser cases, several hours post-vaccination

In other words, it can break down through photolysis (destruction by light) unless you store it properly
