Vitamin B12 injection / working resource

Study reading worksheet

Separate a reported result from the question the study was designed to answer.

Start with the product-specific question

Who it is for

A compounded vitamin B12 injection, with who it is for and what the trials show in plain view. What should I know about injection versus oral B12?

A systematic review and meta-analysis states that vitamin B12 is often used to improve cognitive function, depressive symptoms, and fatigue, that in most cases such complaints are not associated with overt vitamin B12 deficiency or advanced neurological disorders, and that the effectiveness of vitamin B12 supplementation in such cases is uncertain.
