About this study

This randomized, double-blind, placebo-controlled trial will evaluate the effects of daily supplementation with Cordyceps militaris MS-116-04 on exercise performance, endurance, cardiovascular fitness, gastrointestinal wellness, mood, and post-exercise recovery in healthy, active adults.

Participants will complete five study visits over approximately four weeks. Before each visit, participants will follow standardized pre-visit controls, including an 8-10 hour fast, 12 hours without caffeine, nicotine, or alcohol, and 24 hours of no structured exercise.

Visit 1 (Screening/Familiarization) includes informed consent, medical and medication review, anthropometrics, body composition (InBody), screening questionnaires, and familiarization with all exercise testing procedures (VO2max/peak test, 30-minute cycling bout, and Time to Exhaustion [TTE] trial).

Visit 2 (Baseline Part A) includes medication review, questionnaires (SHS-GI, PANAS), adverse event monitoring, and a maximal cycling VO2max/peak test.

Visit 3 (Baseline Part B) includes resting blood samples (serum cortisol, amylase, TNF-α, IL-10), a 30-minute cycling bout at 60% VO2peak, a cycling TTE trial, Borg RPE, and additional blood sampling immediately and four hours post-exercise. A standardized carbohydrate snack is provided during the four-hour recovery period. Participants are then randomized and receive instructions for daily supplementation and compliance tracking.

Visit 4 (End-of-Study Part A; 28-30 days later) mirrors Visit 2 and includes questionnaires, adverse-event review, and a VO2max/peak test.

Visit 5 (End-of-Study Part B; ~72 hours later) replicates Visit 3, including all blood sampling, the 30-minute cycling bout, TTE trial, four-hour recovery period, and standardized snack. Supplement return and compliance calculations are completed at this visit.

Exclusion criteria

Subject has any of the following medical conditions: active heart disease, uncontrolled high blood pressure (≥ 140/90 mmHg), renal or hepatic impairment/disease, Type I or II diabetes, bipolar disorder, Parkinson's disease, unstable thyroid disease, immune disorder (such as HIV/AIDS), any medical condition deemed exclusionary by the Principal Investigator (PI) Subject has a history of cancer (except localized skin cancer without metastases) within 5 years prior to screening.

Subject has a medical condition or orthopedic problem making exercising on a cycle ergometer contraindicated.

Subject has a VO2 peak/max value above the following age/sex categorizations (as measured during Visit 1): Males 20-29y - 47.5 mL/kg/min, Males 30-39y - 46.0 mL/kg/min, Males 40-45y - 43.9 mL/kg/min, Females 20-29y - 41.0 mL/kg/min, Females 30-39y - 39.6 mL/kg/min, Females 40-45y - 38.1 mL/kg/min Subject is currently taking antihypertensives, hypoglycemic medications or stimulatory asthma medications.

Subject is on an unstable dose of medication (defined as fewer than 90 days at the same dose).

Subject is taking a prescription medication deemed exclusionary by the Principal Investigator (PI).

Subject has an allergy to any ingredients in the Study Product. Subject has a history of drug or alcohol abuse in the past 12 months. Subject has a history of a psychiatric illness requiring hospitalization in the past 12 months.

Subject has any condition or abnormality that in the expert opinion of the PI, participation in the study would compromise the safety of the subject or the quality of the study data.

Subject is participating in or has participated in another research study within 30 days prior to the Screening visit.

Primary outcomes

  1. Change in Time to Exhaustion (TTE)

    Time frame: Baseline (Visit 3) to End of Study (Visit 5; approximately 4 weeks).

    To determine whether supplementation with Cordyceps militaris MS-116-04, compared to placebo, affects exercise performance as measured by change from baseline in cycling Time to Exhaustion (TTE), recorded in minutes and seconds.

  2. Change in VO2max

    Time frame: Baseline (Visit 2) to End of Study (Visit 4; approximately 4 weeks).

    To determine whether Cordyceps militaris MS-116-04 affects cardiovascular fitness compared to placebo, as assessed by change in maximal or peak oxygen consumption (VO2max/peak) from baseline to the end of the study.

  3. Change in Gastrointestinal Wellness (SHS-GI Score)

    Time frame: Baseline (Visit 2) to End of Study (Visit 4; approximately 4 weeks).

    To assess whether the Study Product, compared to placebo, impacts digestive and gastrointestinal wellness as measured by the change in Short Health Scale for Gastrointestinal Symptoms (SHS-GI) total score from baseline to end of study.

    The SHS-GI is a validated patient-reported outcome measure consisting of four items, each rated on a 7-point likert scale ranging from 1 to 7, resulting in a total score range of 4 to 28.

    • Higher scores indicate worse gastrointestinal symptoms and poorer gastrointestinal well-being.
    • Lower scores indicate fewer gastrointestinal symptoms and better gastrointestinal well-being.

  4. Change in Mood States (PANAS Score)

    Time frame: Baseline (Visit 2) to End of Study (Visit 4; approximately 4 weeks)

    To evaluate whether Cordyceps militaris MS-116-04 influences mood compared to placebo, as assessed by change in Positive and Negative Affect Schedule (PANAS) scores.

    The PANAS is a validated self-report questionnaire consisting of 20 items, comprising two subscales: positive affect and negative affect. Each item is rated on a 5-point Likert scale ranging from 1 (very slightly or not at all) to 5 (extremely).

    • Positive affect subscale score range: 10 to 50. Higher scores indicate greater positive affect (better mood).
    • Negative affect subscale score range: 10 to 50. Higher scores indicate greater negative affect (worse mood).

  5. Change in Stress Cortisol Across Recovery Period

    Time frame: Pre-exercise (resting), immediately post-exercise, and 4 hours post-exercise at baseline and after approximately 4 weeks of intervention.

    To determine whether the Study Product affects biomarker salivary cortisol measured at rest, immediately post-TTE, and four hours post-TTE.

  6. Change in Salivary Amylase Across Recovery Period

    Time frame: Pre-exercise (resting), immediately post-exercise, and 4 hours post-exercise at baseline and after approximately 4 weeks of intervention.

    To determine whether the Study Product affects biomarker salivary amylase measured at rest, immediately post-TTE, and four hours post-TTE.

  7. Change in TNF-α

    Time frame: Pre-exercise (resting), immediately post-exercise, and 4 hours post-exercise at baseline and after approximately 4 weeks of intervention.

    To determine whether the Study Product, compared to placebo, influences inflammatory responses as measured by salivary Tumor Necrosis Factor-alpha (TNF-α) collected pre-exercise, immediately post-exercise, and four hours post-exercise.

  8. Change in IL-10 concentrations

    Time frame: Pre-exercise (resting), immediately post-exercise, and 4 hours post-exercise at baseline and after approximately 4 weeks of intervention.

    To determine whether the Study Product, compared to placebo, influences inflammatory responses as measured by Interleukin-10 (IL-10) collected pre-exercise, immediately post-exercise, and four hours post-exercise.
