They are pharmaceutically combined as a pill. They can only be seperated related to Analytic Pharmacy but by very expansive lab procedures in pharmacy labs of some universities and in pharmaceutical production companies.

Hi dear coleagues,

Why one would like to split these 3 hydrosoluble vitamins ? Complex-B vitamins are doing a better metabolic job when in synergy all together ! As for fundamental research purposes, just buy them one by one in pure standardised certified aquaous preparations ! Would be faster then spliting ;)

Best, D.O.C.

Dear Sinan Ibaguner , thank you very much for your answer. In Russia there are separated vitamins for intramuscular administration and they are very cheap - 0.4 cents each one (10 ampoules). As I know, vitamin in the pills should be dissolved in the water before absorbed In the intestines. Otherwise, there is no guarantee that in the intestines, after the reaction of the neutralization of the gastric contents, there will be free water bonds to activate inactive forms of vitamins in a tablet, isn`t it?. I have empirical experience in the use of liquid forms of group B vitamins with a better result than in tablet forms and intramuscular injections. Therefore, I would like to know if anyone has the same experience with a liquid vitamin forms for intramuscular administration dissolved in the water, but with a clinical study.

Dear Daniel Constantin Manolescu thank you very much for your answer. I agree with you, together vitamins provides more better metabolic job in synergy . But separated vitamins we can not administer intramuscularly in the same time. Interval has to be 2 hours minimum. Pharmaceutical companies came up with technologies allowing to combine three incompatible vitamins in one ampoule, they say. Absorbed in the blood vitamins are unpacked in stages, also they say. But I have not found information about unpacking vitamins in stages? Do you have information what provide unpack vitamins in stages?
