Multi-Strain Probiotic May Provide Gastrointestinal Benefits
Endurance exercise includes activities that increase your breathing and heart rate such as walking, jogging, swimming, biking, and jumping rope. Endurance exercise has been shown to increase incidences of gastrointestinal (GI) upset. A recent study has found that probiotics may help reduce the incidence of GI incidences in endurance runners.
The researchers recruited 70 long-distance runners who were actively participating in distance running races to take part in the study. They were given 5 billion CFUs of a multi-strain probiotic or a placebo daily for 3 months. The multi-strain probiotic supplement contained the probiotics B. lactis W52, Levilactobacillus brevisW63, L. casei W56, Lactococcus lactis W19, Lc. lactis W58, L. acidophilus W37, B. bifidum W23, and Ligilactobacillus salivarius W24.
Participants completed questionnaires at bassline and at the end of the study period that were used to determine frequency and severity of GI symptoms before, during, and after physical activity. Blood samples were taken at baseline and at the end of the study period to evaluate changes in fasting glucose, total cholesterol, HDL cholesterol, LDL cholesterol and triglycerides, sodium, iron, potassium, magnesium, and calcium.
Participants in the probiotic group self-reported improvements in their general health at the end of the study period. They also saw a lower incidence of constipation compared to the placebo group.
Female participants in the probiotic group saw increases in serum levels of sodium, potassium, iron, HDL cholesterol, and triglycerides. Serum iron and HDL cholesterol levels decreased in female participants in the placebo group and LDL cholesterol levels increased.
The study was conducted by researchers from the Medical University of Bialystok. It was published online ahead of print on July 30, 2022, in the journal Nutrients.
Glucosamine was found to provide gut health benefits in a previous study.
