A further small study done recently on 10 paediatric patients similarly found that intranasal OH-Cbl normalised serum B12 levels in deficient patients (Estourgie-van Burk et al., 2020)
For most patients, a weekly B12 shot for the first four weeks rebuilds depleted B12 levels, followed by maintenance shots every two to four weeks
Furthermore, 6 days of high fat diet in mice suffice to dramatically decrease the levels of phosphorylated signal transducer and activator of transcription 3 (p-STAT3) in the arcuate nucleus (13) while short term overfeeding of normal weight mice can lead to an increase of leptin resistance (14)
If You Have No Absorption Issues : If your body absorbs B12 effectively from the digestive tract, oral supplements can be a great option for maintaining adequate levels over time
