Spore-forming probiotic, BC30, may support amino acid absorption from plant-based protein source, says new study

Results showed that subjects in the BC30 group had significantly higher values for total amino acids and total essential amino acids, as well as higher than average levels of certain amino acids.

Kerry has announced results of a new clinical study showing that the spore-forming probiotic BC30 may help improve protein absorption from plant-based sources. In the double-blind randomized study, whose manuscript is currently in preparation, 30 healthy women between the ages of 50 and 70 each consumed a daily plant-based beverage containing 20 grams of protein from a combination of pea and rice protein, either with or without 1 billion CFU of BC30.

The study duration was two weeks, and after the final dose, blood samples were analyzed for amino acid concentrations. Results showed that subjects in the BC30 group had significantly higher values for total amino acids and total essential amino acids, as well as higher than average levels of certain amino acids.

“Previous research has indicated the potential of BC30 to support protein absorption from plant-based sources, but this is the first human clinical study to do so,” said John Quilter, vice president of global portfolio, ProActive Health, in a press release. “We’re now able to say that BC30 supports protein absorption from both dairy and plant sources – it’s another benefit that makes it the leading spore-forming probiotic.”

A study published in 2020 found that supplementation with BC30 support amino acid absorption following consumption of a milk protein concentrate. “One of the reasons this research is so exciting is that it’s in line with so many contemporary food and nutrition trends,” Quilter added. “With demand for high-protein products firmly in the mainstream, consumers in all groups are interested in foods and beverages that offer efficient protein digestion. At the same time, more and more people are following plant-based diets and looking for sustainable nutrition solutions. Many vegetarians and vegans – along with groups like seniors and athletes – could benefit from more efficient absorption of protein to support outcomes such as muscle-building.”

The study was conducted by researchers at the Exercise and Performance Nutrition Laboratory at the School of Health Sciences at Lindenwood University, Missouri, led by Dr Chad Kerksick, Associate Professor of Exercise Science. A research poster was presented on June 17th, 2022 at the annual conference of the International Society of Sports Nutrition (ISSN). The full study is expected to be published in a scientific journal in late 2022 or early 2023.
