A Trial to Study the Effects of Ginseng and Cordyceps on Aerobic Capacity, Lactate Kinetics, and Nitric Oxide
What this study is about
This study is a where neither patients nor doctors know which treatment is given, randomly assigned, parallel group, three-treatment group$1, compared against an inactive treatment trial of seventy-five (75) apparently healthy male and female participants to be recruited at a single experimental center in Northeast Ohio (i.e., The Center for Applied Health Sciences).
View original scientific description
This study is a double-blind, randomized, parallel group, three-arm, placebo-controlled trial of seventy-five (75) apparently healthy male and female participants to be recruited at a single investigational center in Northeast Ohio (i.e., The Center for Applied Health Sciences). The study will assess the potential benefits of four weeks of supplementation with 300 mg Ginseng or 1 gram Cordyceps Militaris (vs. placebo). Participants will attend 3 study visits. During Visit 1, participants will be screened for participation (i.e., medical history, routine blood work, background baseline diet and familiarization protocol will be completed). During Visit 2 (Day 0) and Visit 3 (Day 30) participants will complete subjective baseline testing including questionnaires that assess recovery, mood, energy, fatigue, and quality of life. They will complete a VO2 max test, a TTE test, isometric mid-thigh pull, and have their handgrip strength assessed. They will also be tested for changes in circulating nitrates/nitrites (NOx), circulatory efficiency (oxygen pulse), and lactate kinetics (production and clearance). Comprehensive side effect profile/ adverse event monitoring will take place throughout thevstudy duration. The study will be conducted following ICH-GCP guidelines to ensure subject safety and scientific integrity of the data.
Interventions
DIETARY_SUPPLEMENT
Panax ginseng
Panax Ginseng extract standardized to 5% ginsenosides
DIETARY_SUPPLEMENT
Cordycep Militaris
Cordycep extract standardized to Cordycepin 0.25% Adenosine 0.15%
OTHER
Placebo
1 gram maltodextrin to mirror 1 gram capsule active
Primary outcome measures
Change in VO2 max from baseline to day 30
Time frame: Baseline and Day 30
Between and within-group changes in maximal aerobic capacity (VO2 max). Oxygen consumption (VO2) for the maximal aerobic capacity test will be measured using an indirect calorimeter
Change in ventilatory threshold
Time frame: Baseline Day 1 and then Day 30
ventilatory threshold (VT) is measured using the The Professional Method (CPET) using the Oxygen consumption data (VO2) measured using an indirect calorimeter
Change in Circulatory efficiency (oxygen pulse) over 30 days
Time frame: Baseline Day 1, then Day 30
Between and within-group changes in maximal in circulatory efficiency (oxygen pulse). Circulatory efficiency (oxygen pulse) will be calculated as the ratio of oxygen uptake (VO2) to heart rate at two time points: @VO2max and @VT
Change in Time-to-Exhaustion (TTE) over 30 days
Time frame: Day 1 and Day 30
Between and within-group changes in time-to-exhaustion (TTE). A cycle ergometer will be used for all cycling exercise sessions and contain a digital time reading.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Provide voluntary signed and dated informed consent.
- Be in good health and able to participate in cognitive performance testing as determined by assessment, medical history, and routine blood chemistries.
- Between the of 40 and 65 years of age (inclusive).
- Body Mass Index of 18.5-34.9 (inclusive).
- Body weight of at least 110 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 supine, resting heart rate (\<90 per minute).
- Able to provide an adequate blood draw.
- If a dietary supplement was initiated within the past month, the participant is willing to discontinue supplement use followed by a 2-week washout prior to participation in the study.
- Willing to duplicate their previous 24-hour diet, refrain from caffeine and alcohol for 24 hours, refrain from exercise for 48 hours prior to each trial, and fast for 10 hours prior to each visit.
- Recreationally active (≥3 exercise sessions/wk)
Exclusion criteria
- 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 (Lapband, etc.).
- Other known gastrointestinal or metabolic diseases that might impact nutrient absorption or metabolism, e.g. electrolyte abnormalities, diabetes, thyroid disease, adrenal disease, hypogonadism, short bowel syndrome, diarrheal illnesses, history of colon resection, gastric ulcer, reflux disease, gastroparesis, Inborn-Errors-of-Metabolism (such as PKU).
- Chronic medically diagnosed inflammatory condition or disease (e.g. rheumatoid arthritis, Crohn's disease, ulcerative colitis, Lupus, HIV/AIDS, etc.).
- Medical history of metabolic, cardiovascular, hepatorenal, musculoskeletal, autoimmune, or neurologic disease.
- Use of performance enhancing drugs
- Anti-inflammatory supplement/medication use started within 4 weeks
- Ergogenic supplement use started within 4 weeks. (i.e. beta-alanine, creatine, beet root, citrulline, arginine, )
- Individuals with excessive caffeine intake (\>400mg/day).
- Known sensitivity to any ingredient in the test formulations as listed in the Certificates- of-Analysis.
- Women currently pregnant, trying to become pregnant or breastfeeding a child.
- Any other diseases or conditions that, in the opinion of the medical staff, could confound the primary endpoint or place the subject at increased risk of harm if they were to participate

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
