B12 injections work differently by providing a direct and efficient way to restore your energy levels
So, we recommend using SL vitamin B12 rather than oral and IM, especially in patients who do not tolerate IM injection and patients who need prolonged vitamin B12 supplementation, such as patients with long-term metformin use and patients with pernicious anemia or with gastro-duodenal resection [51,52,53,54]
If you aren't deficient you will likely not feel any benefit from the shot, however the vitamin is water soluble so any excess B12 is secreted through our waste system causing no harm
When we take any vitamin supplements orally, we lose much of what the vitamin offers through the liver and digestive system, decreasing the supplements bioavailability
