Description
Anyone selling you a precise human bioavailability figure is guessing
But I don't use it sublingually because B12 molecules can't pass through the buccal (tongue ) membranes
That is when you start feeling tingling, numbness, weakness, or brain fog
& Rutter, G
A B12 injection goes straight into the muscle, so your body gets what it needs fast
