Does anyone know this conversion? I have been taking 1000mcg b12 dose for years. As soon as I became hypothyroid.I couldn’t get to Holland and Barrett for my usual brand, and ended up in boots that only had doses of 10ug
Does anyone know how this fares with 1000mcg? The pharmacist in boots openly admitted she didn’t have a clue.
Just trying to work out how many of the UG ones to take.
Thanks
