V•Nella contains the proprietary FitBiomics strain Veillonella. This novel microbe naturally eats lactic acid, a by-product associated with fatigue, and converts it into beneficial short-chain fatty acids that fuel your body.
8-week placebo controlled study found Veillonella significantly reduces multiple categories of fatigue in a sustained and enduring manner, and increases physical activity.
I don’t think I will be buying this anytime soon.
“Veillonella parvula is a Gram-negative commensal microorganism and a causing agent for dental caries and periodontitis. It acts as opportunistic pathogen upon suitable growth conditions for the bacterium.”
I’m thinking scam until proven otherwise. Is it really Lactic acid that causes fatigue? Do you lose the advantageous aspects of lactate? How does this microbe get into muscle? Any studies not funded by manufacturer?
I remember seeing a video/documentary about a long distance runner in the US who could run for hours…never got sore or tired. Turns out he has some unique way of removing the lactic acid from his muscles. I’m guessing his ability was due to a mutation, not by being a bioreactor for Veillonella.
Seems to be based on old science.
Lactic acid is fuel for your cells during intense exercise. It’s created when your body breaks down glucose and other carbohydrates. It’s a common myth that muscle soreness you feel after exercise is caused by lactic acid trapped in your cells. Studies have found that’s not true.
Ugh…Chris Masterjohn posted this this morning I think:
I tried to read it for a while, will work on it later when I have more time.
Most cells in your body love to “eat” lactate. It’s a fuel not a cause of fatigue. The chemistry is beyond me but I understand that when fast twitch muscle fibers (with little mitochondria) burn glucose without oxygen, lactate is produced and used by nearby muscle cells with mitochondria to burn as fuel with oxygen. When the amount of lactate produced exceeds the local muscle areas ability to burn the lactate, it gets exported to the blood stream to be used by other organs. There is always some lactate in the blood stream but once the level spikes up, it’s a sign of working the muscle at an unsustainable pace.
The lactate gets produced along with hydrogen (an acid) which can reduce the pH of the muscle which reduces the muscles ability to function. But that is an acute fatigue. It feels like your muscle won’t work. It goes away quickly (faster if you keep moving).
I believe real fatigue is a drop in glycogen stores which is related to lactate since lactate is made from glucose which was stored as glycogen in the muscle. So, refueling during exercise can help.
