Why can't I buy calcium pantothenate? Can't buy it! Because all foods contain calcium pantothenate, there is no typical calcium pantothenate deficiency in medicine! Similarly, vitamin B 12 is widely found in meat. Few people lack it, and the intake of vitamin B 12 is too high, which greatly increases the risk of malignant tumor! Because of this, vitamin B complex does not contain B5 and B 12, so it may not be available or it is difficult to buy it separately.
