NCT05657314

Brief Summary

This study is a double-blind, randomized, placebo-controlled, crossover clinical trial of N=40 recreationally active men to be recruited a single investigational center in Ohio (i.e., The Center for Applied Health Sciences). Subjects will take a daily protein supplement (e.g., 15 g of pea protein or 15 g of pea protein + probiotic blend) for 4 weeks, have a 1-week washout period (i.e. meaning they will not take either supplement), and then take the alternate protein supplement for an additional 4 weeks. Outcome variables include plasma amino acids, muscle damage, muscle recovery, and GI tolerance.

Sexmale
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Provide voluntary signed and dated informed consent.
  • Be in good health as determined by medical history and routine blood chemistries.
  • Age between the ages of 18 and 55 (inclusive).
  • Body Mass Index of 18.5-29.9 (inclusive).
  • Subject agrees to maintain existing dietary patterns throughout the study period apart from ingesting the provided treatment beverage.
  • Subject is willing and able to comply with the study and supplement protocol.

  • Subject agrees to abstain from strenuous exercise 72 hours prior to testing on all study visits.
  • Body weight of at least 120 pounds.
  • Normotensive (seated, resting systolic blood pressure \<140 mm Hg and diastolic blood pressure \< 90 mm Hg. If the first measurement is slightly elevated above these limits, the subject will be given a brief (5 minute) rest period, and two more measurements will be taken. The average of all three measurements will be used to determine eligibility.
  • Normal seated, resting heart rate (\<90 per minute).
  • Willing to duplicate their previous 24-hour and fast for 8 hours prior each study visit.

You may not qualify if:

  • Individuals who have been diagnosed with liver, renal, cardiovascular, or other metabolic disease.
  • Use of any dietary supplements which may confound the study or its endpoints, including creatine, BCAA, HMB, betaine, beta-alanine, etc.
  • Use of any prescription medications (particularly antibiotics and/or anti-inflammatories), or probiotics within the past 2 months which may confound the study or its endpoints.
  • Alcohol consumption (more than 2 standard alcoholic drinks per day or more than 10 drinks per week) or drug abuse or dependence.
  • Smokers.
  • Clinically significant abnormal laboratory results at screening.
  • Known sensitivity to any ingredient in the test formulations as listed in the Nutrition Facts label.
  • Individuals who are cognitively impaired and/or who are unable to give informed consent.
  • Individuals with diabetes, asthma, chronic inflammatory conditions (e.g., rheumatoid arthritis, colitis, IBS/IBD, gout or fibromyalgia, Crohn's disease, ulcerative colitis, Lupus, HIV/AIDS, etc.).
  • Other known gastrointestinal or metabolic diseases that might impact nutrient absorption or metabolism, e.g., short bowel syndrome, diarrheal illnesses, history of colon resection, gastro paresis, Inborn-Errors-of-Metabolism (such as PKU).
  • Individuals with excessive caffeine intake (600mg/day).
  • Subjects who take medication which may adversely affect the measured outcomes (i.e., testosterone or other anabolic steroids, corticosteroids or testosterone replacement therapy (ingestion, injection, or transdermal), diuretics, etc.)
  • History of malignancy in the previous 5 years except for non-melanoma skin cancer (basal cell cancer or squamous cell cancer of the skin).
  • Prior gastrointestinal bypass surgery (i.e., Lapband, etc.).
  • Women
