I notice a real slump in energy when i get a bit slack taking B12 Cynno, even though i still take a multi B & vit C every day.
When i first started to taking b12, i took 2 to 3 mg B12 Cynno every day for 3 months then got a b12 test done and was only 750 approx, Rose said i must have been malasorbing badly to get a reading like that, so i will never stop taking it.
I eventually got my Bobo Visa card and ordered b12 Methyl from Iherb today.
