Researchers found the bacteria after studying the 10 Boston Marathon trails. To generate energy for itself, Veillonella breaks down lactic acid that is produced at a higher level when athletes perform particularly tense activities. To determine if bacteria make a difference, scientists isolate a strain of it and insert it into 1
6 mice, then place them on a treadmill. Mice with bacteria in their stomachs have managed to climb 13% longer than mice that do not benefit from Veillonella – a small difference, but one that can make a huge difference in athletic competition where every little advantage  While Veillonella shows a promise as a potential productivity enhancer, it is still at an early stage in the research stages. The test indicates a possible positive feedback between the bacteria and the host, but it is unclear whether it will be passed on to humans in the same way or if it is safe to consume. Plus, there are many questions that still need answers, including why it seems that bacteria are more common in some people if their use is considered to be a performance enhancer that can be considered a scam.
