Yeast Protein for Muscle Mass

Plain-language summary
Protein supplementation is said to be one of the cost-efficient and practical strategies to meet protein needs for growth and exercise, and can help maximize muscle gain from resistance exercise. It facilitates faster recovery from stress-induced tissue damage and enhances performance output. Protein sources derived from animal products are generally recognized as the highest quality protein. However, altering the protein composition of a protein source can improve the protein quality. The yeast protein supplement the investigators will use in this study has a similar amino acid composition to whey protein, which is derived from an animal product, but it is produced more sustainably. The study aims to compare the effects of yeast and whey protein on muscle mass over 16 weeks.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Participants must have the ability to read, understand, and sign an informed consent and must be willing to comply with study treatment and follow-up.
* Prior resistance training experience (defined as performing resistance exercises \>1/week for the past 3 months or longer) to enable them to reach a large training stimulus relatively quickly and to avoid the longer phase of neuromuscular adaptations
* ≥18 years and \<35 years of age
Exclusion Criteria:
* Diabetes, musculoskeletal disease, cancer, Crohn's disease, or any other acute or chronic condition that interferes (or the medication prescribed for those conditions) with muscle anabolism.
* Diagnosed with or being treated for heart disease, stroke, high blood pressure 130/80 mmHg or higher
* Pain/discomfort/pressure in the chest during activities of daily living or physical activity
* Pregnant or not on adequate contraception.
* A known hypersensitivity/allergy to ingredients in the supplements.
* Inflammatory bowel diseases
* Enrolment in any other clinical protocol or investigational study that may interfere with study procedures
* Taking antibiotics
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
