I have researched a few things to increase appetite as well as energy and have come up with the best solution of b12, now I have oral(pills) of b12 and can get the injectable. But can someone explain why wouldnt the pills work the same. My guess would only be some of the effects could be lost after passing thru the stomache. If someone could shed some light on this question it would be great, and would the pills be ok to use for what i am looking to get out of this.....thanks guys!
