Probiotics has been a buzzword for the last decade or so, with nutritionists and doctors touting their benefits in yogurt, kefir, kombucha and sauerkraut. There are also countless forms of probiotic supplements lining the shelves of health food and grocery stores. But new research indicates that they could be to blame for abdominal bloating and brain fog.
The study on probiotics
A new study from the August University in Georgia looked at 30 people who were experiencing gas, distention and bloating. Of these study participants, 22 were also experiencing “brain fog,” a general term for temporary problems with confusion, memory difficulties and issues with concentration. All 22 of these participants were taking probiotic supplements. Some of the people were taking more than one brand.
The 22 participants with brain fog were also more likely to experience higher blood levels of D-lactic acid and an accumulation of bacteria in their small intestine.
It seems that when the 22 participants took lactobacillus bacteria, which is one of the most commonly used probiotics, it would make the acid by fermenting sugar in the food as it goes through the gut.
Once the 22 participants went off the supplements and went on antibiotics, the brain fog cleared and the abdominal symptoms improved significantly.
Should you stop taking probiotics?
The short answer is “no,” unless you’re having problems, like those mentioned above. But take them in moderation and ensure that what you’re taking are high quality. Because probiotics are classified as dietary supplements, they’re not held to the same rigorous products standards as something that would be put through FDA regulations.
Buy probiotics from a manufacturer you trust (i.e., a brand you recognize or that as a stellar reputation). You can also get the benefits from food, such as yogurt, and weigh the pros and cons, depending how you feel.
Probiotics definitely have some benefits, especially for people whose “good” gut bacteria has been wiped out from taking antibiotics. When in doubt, consult with a doctor or nutritionist to get their advice.
