                                Studies have shown that vitamin B12 absorption from oral supplements can be as low as 1.3% compared to the high efficacy of injections, which can absorb 55-97% of the dose. This stark difference highlights a key consideration when deciding between vitamin B complex injections or tablets for supplementation.
