Research investigating pH-dependent conformational changes could elucidate stability mechanisms
It also means that foundational knowledge about proper handling protocols is more important than ever
The Bottom Line The risk of vitamin B12 deficiency may not be an obvious threat to people living with diabetes, but you should take it seriously
The use of H(2)-receptor antagonists and/or PPIs may impair the absorption of protein-bound dietary vitamin B12 and could contribute to the development of vitamin B12 deficiency with prolonged use.[189] The studies reviewed in this article clearly show that omeprazole therapy will decrease the absorption of vitamin B12 by preventing its cleavage from dietary proteins.[190] A number of studies have shown an association of decreased B12 absorption with prolonged PPI use.[189,190] However, PPIs have been shown to affect B12 absorption in very short periods of time as well.[191,192] One study showed a 72% decrease in B12 absorption on 20 mg of omeprazole (Prilosec) and an 88% decrease in B12 absorption on 40 mg of omeprazole after only 2 weeks of treatment
