As a former nurse, I have given hundreds of injections of all types, at all possible injection sites, for innumerous reasons and with differing patient tolerances
Vitamin b12 is crucial for brain functioning where, sadly, a deficiency can lead to anxiety and depression
B 12 deficiency can cause preventable permanent injury and should be considered with new onset neurological conditions and symptoms suggestive of B 12 deficiency (See Low B 12 symptoms section below)
Which one to choose Pick the B12 IM injection when: You only want B12, not hydration or other vitamins You want the fastest, lowest-cost visit You are on a regular B12 cadence (weekly, biweekly, monthly) and want it to be a quick stop Your physician has flagged low or low-normal B12 on bloodwork and recommended supplementation Pick the IV with B12 added when: You also want fluids (post-travel, post-event, training recovery) You want a broader vitamin and mineral panel in the same session You are coming in for a Myers Cocktail or hydration drip already, and adding B12 is a small marginal cost You want to combine B12 with glutathione or a NAD+ session What clients actually do at Dripology Most regulars use both at different times
