Vit B12 can be supplemented via pills or injections.
I think that pills are better in that they are easy to administer even with food.
The injections are better when the lack of Vit B12 is due to a GI issue that prevents the absorption of the vitamin through the digestion. The con of the injections is that the fluid stings a lot.
The injections must be administered according a schedule tha you shoud get from your vet.
Pills can be given daily, like I used to do with my cat.
Check if your Salmon Oil has B12 in it and which amount.
