I had/have a B12 deficiency which I was treating with high dose lozenges every other day and my level went from 173 too over 5 hundred. On falling pregnant I started taking mum too be vits with very low 100 percent Rda b12 so much lower than 5000mcg but I started taking the big dose once a week too keep my levels topped. I've yet too have b12 checked midwife requested my next thyroid bloods include b12 levels. So now today I read in the telegraph high b12 linked too autism and now I'm scared I've done the wrong thing without checking first.
I've started getting ear ringing again so I can only assume my levels are dropping
Any advice thanks
