A study recently published in Nature Communications revealed that an affordable supplement taken daily can improve cognitive function in seniors. Researchers from TwinsUK wanted to see if using inexpensive fiber prebiotic supplements to target the microbiota could improve brain function and muscle health. Over a period of 12 weeks, 36 pairs of twins over the age of 60 were given either the supplement or a placebo each. It was a double-blind study, meaning that neither the participants or the researchers knew who was receiving which treatment until it was complete. Let’s take a look at what they discovered in the article below.
The Inexpensive Supplements That Could Improve Brain Function in Seniors
The participants were required to drink a protein powder that either contained the supplement or a placebo and do resistance exercises. They were monitored remotely via video and were required to fill out various questionnaires and cognitive tests. The researchers found that taking the supplement resulted in considerable gut microbiome changes, specifically a marked increase in Bifidobacterium, considered a beneficial bacteria. No difference in muscle strength was observed between the two groups. However, the group that had taken the supplement exhibited improved brain function in their tests. This included tests that determined early markers for Alzheimer’s, processing speed, and reaction time.
This is important information, as it determines how well a person would react to everyday situations, such as preventing a fall mid-trip or reacting to sudden changes in traffic. Another important aspect of this study was that it proved that it was possible to conduct trials with seniors remotely. This means that the participants did not need to travel far for hospital visits and researchers likewise did not have to travel to make observations. However, there were certain limitations to the trial that will need to be addressed in future studies. For example, not every senior person has access to technology or is computer literate.
