What this study is about
The goal of this clinical trial is to learn if a dietary supplement called Miricell works to improve cellular health and signs of healthy aging in adults. It will also learn about the safety of Miricell.
View original scientific description
The goal of this clinical trial is to learn if a dietary supplement called Miricell works to improve cellular health and signs of healthy aging in adults. It will also learn about the safety of Miricell. The main questions it aims to answer are: * Does Miricell improve markers of autophagy, which is the body's natural process for recycling damaged cells? * Does Miricell support brain health, metabolic health, and visible signs of aging? * What medical problems, if any, do participants experience while taking Miricell? Researchers will compare Miricell to a placebo (a look-alike capsule that contains no active ingredients) to see if Miricell works better to support healthy aging. Participants will: * Take either one Miricell capsule or a placebo every day for 12 weeks with a morning meal. * Visit the research clinic four times over the course of the study for checkups and tests. * Complete memory and thinking tests, track their daily physical activity, and give blood samples to measure health changes.
Interventions
DIETARY_SUPPLEMENT
Spermidine
Branded spermidine ingredient (Miricell® Rice Germ Extract) administered orally at a dose of 3.3 mg/day. Provided as a single opaque capsule to be ingested daily with water in the morning with a meal.
DIETARY_SUPPLEMENT
Placebo
Placebo capsule (microcrystalline cellulose) packaged in an identical-looking, opaque capsule to be ingested daily with water in the morning with a meal.
Primary outcome measures
Serum Beclin-1 Concentration
Time frame: Baseline (Week 0), Week 6, and Week 12
Measures the change from baseline in serum Beclin-1 levels to assess autophagy activation.
Serum ULK1 Concentration
Time frame: Baseline (Week 0), Week 6, and Week 12
Measures the change from baseline in serum ULK-1 levels to assess autophagy activation.
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 fair health as determined by medical history and routine blood chemistries.
- Age between the ages of 40 and 70 (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 seated, resting heart rate (\<90 per minute).
- Willing to duplicate their previous 24-hour diet, refrain from alcohol for 24 hours, exercise for 24 hours prior to each trial, caffeine for 12 hours prior to each trial, and fast for 10 hours prior to each of the treatments.
- Participant agrees to maintain existing dietary and physical activity patterns throughout the study period.
- Participant is willing and able to comply with the study protocol.
- 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.
- Able to provide an adequate blood draw.
Exclusion criteria
- Use of probiotics, postbiotics or antibiotics within the past month.
- A history of unstable or new-onset cardiovascular/cardiorespiratory, liver, or renal disease.
- The participant's alcohol consumption is more than two standard alcoholic drinks per day or more than 10 drinks per week or has a history of drug/alcohol abuse or dependence.
- History of diabetes (any form) or any endocrine disorder.
- Fasting blood sugar of \> 125 mg/dL.
- Current smokers who smoke 11 or more cigarettes per day (i.e. light smokers will be enrolled if they meet all other criteria).
- History of hyperparathyroidism or an untreated thyroid disease.
- History of malignancy in the previous five years except for non-melanoma skin cancer (basal cell cancer or squamous cell cancer of the skin).
- Chronic inflammatory condition or disease (e.g., rheumatoid arthritis, Crohn's Disease, ulcerative colitis, lupus, HIV/AIDS, etc.).
- Previous medical diagnosis of gout or fibromyalgia.
- Any female who is pregnant, trying to become pregnant, is less than/or equal to 120 days postpartum, or any current women who are nursing.
- Women who participate in this study must agree to the use of contraception for the duration of the study, and any sexually active woman will have to take a negative pregnancy test prior to enrolling. Women of childbearing age (any woman prior to menopause), regardless of their use of contraception, will be provided a urine pregnancy test kit at their screening visit and take the test in private using the female lavatory after signing an informed consent.
- Known allergy or sensitivity to any ingredient in the test formulations as listed on the product label.
- Any other diseases or conditions that, in the opinion of the medical staff, could confound the primary endpoints 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.
