firflymairi - as per Foggyme's response below we don't recommend using a dried product that would have to be mixed with sterile saline unless you can ensure that this is being done in a sterile environment because of the risk of contamination.It can also be difficult to source sterile saline for injections as, like B12, it's a prescription only if supplied for medical use and you would really need to be using medical grade saline
While many individuals can benefit from B12 injections, certain groups may see more significant or rapid improvements: Vegetarians and Vegans Plant-based diets are often low in B12, making supplementation crucial
If it's not, you may only need an injection every 2-3 months for life
That number alone tells your doctor almost nothing about whether your therapy is actually safe, effective, or sustainable long-term
It can cause fatigue, weakness, constipation, loss of appetite, and weight loss
