Protein Powders for Nutrition
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to understand how the body processes different protein powders. Participants will consume two types of protein products: a fast-digesting milk protein (milk protein concentrate) and a slow-digesting micellar casein (micellar casein isolate). Researchers will measure the absorption rate of amino acids (the building blocks of proteins) in the small intestine and its impact on digestion. Ideal candidates for this study are healthy individuals who can maintain their usual diet and activity levels, have no major gastrointestinal issues, and are not on regular prescription medications. As an unphased study, this trial allows participants to contribute to foundational research on protein digestion.
Will I have to stop taking my current medications?
The trial requires that you do not use regular prescription medications that could affect the study's safety or outcome. If you are taking medications that alter gastrointestinal function, you may need to stop them a week before the study, except for laxatives and proton pump inhibitors, which have specific guidelines. Please consult with the study team for more details.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that Micellar Casein Isolate (MCI) is often used in food products and is generally well-tolerated. This protein is commonly found in sports nutrition items like shakes and bars. Reports of harmful side effects are rare when used as directed for nutrition.
Milk Protein Concentrate (MPC) is also popular in protein powders and shakes. However, a small concern exists. Some studies have found that protein powders can sometimes contain high levels of heavy metals like lead. This doesn't mean every product has this issue, but it's something to consider when choosing protein supplements.
Both proteins are used regularly by many people without major safety concerns. However, staying informed and choosing products carefully is always advisable. Before joining a trial, consider discussing these points with the study team.12345Why are researchers excited about this trial?
Researchers are excited about Micellar Casein Isolate (MCI) and Milk Protein Concentrate (MPC) because they offer unique nutritional benefits compared to standard protein supplements like whey or soy proteins. Unlike other treatments that primarily focus on rapid digestion, MCI is known for its slow digestion, which provides a prolonged release of amino acids and may enhance muscle protein synthesis over time. On the other hand, MPC combines casein and whey, potentially offering both fast and slow-release proteins in one product. This combination could provide a balanced approach to muscle recovery and growth, appealing to those seeking optimal nutrition post-exercise.
What evidence suggests that this trial's treatments could be effective for nutrition?
This trial will compare the effects of Micellar Casein Isolate (MCI) and Milk Protein Concentrate (MPC) on muscle health and physical performance. Research has shown that MCI can improve muscle endurance and reduce tiredness during workouts by slowing protein breakdown, aiding muscle recovery and growth over time. MPC, on the other hand, has been linked to increased muscle strength and lean body mass, especially when combined with strength training. It also boosts appetite and improves certain health markers, benefiting overall well-being. Both proteins provide essential building blocks for muscle repair and growth. Participants in this trial will receive both MCI and MPC in different intervention periods to assess their effectiveness in promoting muscle health and enhancing physical performance.678910
Are You a Good Fit for This Trial?
This trial is for healthy individuals interested in how their bodies digest different protein powders. Participants will try two types of proteins: a fast-digesting milk concentrate and a slow-digesting casein isolate. Specific eligibility details are not provided, but typically participants should have no major health issues.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- Micellar Casein Isolate
- Milk Protein Concentrate
Trial Overview
The study compares the digestion of two protein supplements: Milk Protein Concentrate (fast-acting) and Micellar Casein Isolate (slow-acting). Healthy volunteers will consume each product during separate phases to assess amino acid levels and gastric emptying rates.
