why do i feel so tired after b12 injection Injections Help with Fatigue and Low Energy? Why Do I Feel Worse

Some people use B12 injections as a short-term boost during high-stress times, while others make them a regular part of their wellness routine

Here are some of the vitamin B12 supplements your doctor may give you: Vitamin B12 injections (typically, 1 to 2 mg of hydroxocobalamin injected into your muscles every other day for two weeks) Vitamin B12 tablets (once your levels are stabilized) Folate (your body needs folate to process vitamin B12 and vice versa) L-methionine (B12, folate, and L-methionine work together) Your doctor may also want to check to see if you need other treatments because of a problematic immune response or another deficiency

The kidneys are responsible for clearing excess B12 from the blood

This improvement manifests as better nutrient partitioning, where incoming calories are more likely to be used for energy or muscle building rather than stored as fat
