I have heard that the injection does help if you have a genuine deficiency. They are apparently very effective at raising low B12 levels and can improve symptoms like fatigue, weakness and nerve issues caused by the deficiency. They are not a general energy booster, but when B12 is low, they can make a difference.

No I haven’t had one but I’ve been interested reading about those that have. I take vit b tablets – they are by RN labs and have 1000 strength
You place one under your tongue and let it dissolve to absorb quickly into your body. They are tasty and so I actually look forward to taking them

A decade ago, I was given a regime of B12 injections because I was low in B12. My doctor arranged for me to have daily injections for a fortnight, then twice weekly injections for 2 months and then once a week for 6 months. This helped me although it took a while to notice. My annual blood test now includes a check of my B12 levels and I take a daily B12 pill. I recommend you follow your doctor’s advice.

I would be inclined to follow your GPs advice – they generally know what they’re doing. I’ve never had a B12 injection, but every time we have been recommended to have a supplement or transfusion, it has helped significantly. Plus, so far as I’m aware, one injection couldn’t do you any harm if she/he is wrong.

I had one of these a few years ago and found it amazing, it was really helpful and i recommend getting it done if your doctor has suggested it however please do your research before agreeing just to make sure it is right for you as i know these can cost money to have.

I have actually just had them done recently but the Dr GP only gave me 3 B12 Injections but to me I have not seen much of a difference as yet they say it gives you more energy well I have a little extra bit not to the extent of like running here and there flying off the walls hahaha

Have not had the B 12 injections myself but a friend has had numerous ones and says that they do boost her energy etc., and she does feel the benefit from receiving the injections on a regular basis as she has many medical conditions that warrant her needing to have them.
