Amino Acid Absorption with Probiotic and Milk Protein

This study is looking at how adding a single strain probiotic to milk protein affects your body's ability to absorb amino acids (the building blocks of protein). Researchers want to see if the probiotic changes how quickly and how much amino acid your body takes in. You might be able to join if you are a healthy male or female between 18 and 35 years old and haven't used nutritional supplements or performance-enhancing aids recently. The study will measure the rate and concentration of amino acid absorption at the beginning, after 22 days, and after 65 days. The current recruitment status is unclear.

Study design
This is a randomized, double-blind, crossover study involving 30 healthy men and women. This means participants will be randomly assigned to receive either the probiotic or a placebo, and neither they nor the researchers will know which they are receiving. Participants will also switch treatments after a break.
What's involved
You would participate in two three-week supplementation periods, separated by a three-week break. Each period involves daily intake of a supplement and several visits to the lab for measurements and blood draws after fasting.
Compensation
Not stated in the trial record.
Follow-up
Your amino acid absorption will be measured at Day 0, Day 22, and Day 65.

What this trial measures

  • Rate of amino acid absorptionDay 0, Day 22, Day 65

    To determine if the addition of a probiotic to milk protein ingestion changes the rate (in minutes) to which amino acids are absorbed into our bloodstream.

  • Concentration of amino acid absorptionDay 0, Day 22, Day 65

    To determine if the addition of a probiotic to milk protein ingestion changes the extent (concentration in millimoles/Liter) to which amino acids are absorbed into our bloodstream.
