A 2025 meta-analysis of 16 studies involving 6,098 participants found no statistically significant difference between intramuscular, oral, and sublingual B12 supplementation routes (p=0.270)
If unsure, a good rule is to mimic the conditions where the peptide is known to be stable (often the lyophilized form includes hints, e.g., lyophilized from 10 mM acetic acid suggests reconstituting in slightly acidic water might be wise)
