Upon closer inspection I see that the vitamin B12 is more than 100 times the RDA (recommended daily allowance) of 2.4 mcg/day. Yes, seriously, 100 times! No products in other countries do that, probably because it would be illegal.
Maybe Pure Encapsulations does it because it provides a little feeling of boost or something - I can't imagine why else they would do something so unwise - but it can't be healthy.
Also not sure why it would have "'Inositol" but that is a minor quibble compared to the B12 levels!
