Vitamin B12, also known as cobalamin or cyanocobalamin, could help with men’s issue of premature ejaculation (PE). A study published on Sept. 29 in the journal Andrologica found that lower levels of vitamin B12 are associated with the presence of premature ejaculation.

Experts define PE as ejaculating in less than two minutes.  The study involved analyzing 109 subjects, 56 of who have PE and 53 controls.

The researchers evaluated the participants with the premature ejaculation diagnostic tool (PEDT), International Index of Erectile Function (IIEF) and Beck Depression Inventory (BDI). They also analyzed the participants’ vitamin 12 levels.

The research team found that PE patients have significantly lower vitamin B12 levels in comparison to the controls. Overall, patients with premature ejaculation have vitamin B12 level of around 213.14 vs. 265.89 ng ml.

Now this prompted some to believe that foods rich in the vitamin, particularly Marmite, can cure PE. The Daily Mail reported that Marmite, along with meat, fish, eggs and fortified breakfast cereals are among the best sources of vitamin B12 could help the condition.

However, the researchers did not test Marmite. The team did not claim that having high levels of vitamin B12 is effective in treating premature ejaculation. However, the study only links lower levels of the vitamin with PE. also pointed out that there is no research that proves that PE needs different therapeutic regimen, as reported by the Daily Mail. Daily Mail also reports that multiple treatment regimens have been proven to be effective in extending the time between penetration and ejaculation, which is also unsupported by research.

WebMD states, “In many cases premature ejaculation gets better on its own over time. Treatment may not be needed. Practicing relaxation techniques or using distraction methods may help you delay ejaculation. For some men, stopping or cutting down on the use of alcohol, tobacco, or illegal drugs may improve how well they can control ejaculation.
