This timeline matches B12 pharmacokinetics: intramuscular methylcobalamin reaches peak serum concentration at 8-12 hours, but tissue saturation (particularly in the liver and nervous system) occurs over 48-72 hours as the vitamin is transported into cells and converted to active coenzyme forms (Andrs et al., 2018)
Enzymes such as lipase appear to play a critical role in this process, helping in the breakdown of these fats
This causes the immune system to make substances that cause the symptoms of illness, like brain fog, appetite loss, and reduced interest in your favorite activities
From a pharmacokinetic perspective, studies indicate no evidence that the combination of Vitamins B1, B6, and B12 adversely affects the pharmacokinetics of each individual vitamin
