This study evaluates the effect of two different doses of a consumer-grade product, MyCondro™, on individuals experiencing mobility issues related to knee osteoarthritis. The primary goal is to measure improvements in overall joint health and mobility by tracking changes in participants' total WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index) scores from the beginning to the end of the trial. Additionally, the study aims to assess secondary outcomes, including the product's impact on pain, stiffness, knee function, patient-reported improvement, inflammatory blood markers (CRP), and daily physical activity.

This decentralized, consumer-driven clinical study is designed to evaluate the impact of two different doses of MyCondro™, a consumer-grade product, on physical mobility and joint health in adults aged 45 and older with self-reported knee osteoarthritis. The primary objective is to assess the change from baseline in the total Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score within each dose group by the end of the trial. Secondary objectives will measure the product's effect on pain, stiffness, knee function, subjective impression of improvement, and inflammatory blood markers (CRP), alongside objective digital metrics of physical activity tracked via wearable devices. Because this research utilizes a direct-to-consumer model-where participants make an informed choice to enroll and collect data at home without a traditional doctor-patient relationship-the findings will provide highly relevant, real-world knowledge regarding the product's tolerability and efficacy to guide the formulation and design of future studies.

The double-blind study spans up to 20 weeks, encompassing a screening period, randomization and shipping, a baseline phase, and a 12-week product use period. Eligible participants are randomly assigned to receive either a 300mg or 600mg dose of the study product, with the investigators, study team, and participants remaining blinded to the group assignments. All trial activities are conducted remotely using the Consumer Health Learning and Organizing Ecosystem (Chloe) app by People Science. Through this web-based platform, participants will securely submit demographic data, medical history, and patient-reported outcome surveys. By combining these app-based questionnaires with at-home blood sample collection kits and wearable health tracking technology, the study aims to successfully and safely capture comprehensive health data entirely within the participant's home setting.

Inclusion Criteria:

• Individuals age 45 years and older.
• BMI range between 18-35 kg/m².
• Self-reported mobility issues, including mobility impairment and joint discomfort associated with a known diagnosis of Knee Osteoarthritis. This impairment and discomfort must have persisted for at least 6 months prior to randomization and have been actively experienced within the last 3 months.
• Willingness to avoid high Chondroitin Sulfate-containing foods (i.e., animal cartilages, bones, or derivatives such as gelatin) for the duration of the study period.
• Willingness to refrain from supplements containing Chondroitin Sulfate for the duration of the study period.
• Able to read and understand English.
• Able to read, understand, and provide informed consent.
• Able to use a personal smartphone device and download the Chloe by People Science app.
• Able to receive shipments of the product at an address within the United States.
• Able to complete study assessments over the course of up to 16 weeks.

Exclusion Criteria:

Any potential participants will be excluded if they meet any of the following criteria:

• Technology Limitation: Do not have a personal smartphone, lack internet access, or are unwilling to download the Chloe app.

• Concomitant Therapies

  1. Use of a Chondroitin Sulfate supplement in the 3 months prior to randomization.
  2. Current use of other joint health supplements (e.g., glucosamine, hyaluronic acid, collagen peptides) for at least 4 weeks prior to randomization.
  3. Use of any intra-articular or intravenous steroid injections in the last 3 months.
  4. Receiving any investigational therapies or treatments within 30 days prior to randomization.

Other Illnesses or Conditions

1. Self-reported inflammatory arthropathies, such as Rheumatoid Arthritis, Gout, and Infectious Arthritis.
2. Significant systemic lung, liver, heart, or kidney disease (excluding hypertension).
3. Prior history of knee surgery within 3 months preceding the study period, or planned knee surgery (including arthroscopy) during the study period.
4. Currently diagnosed with Alcohol Use Disorder and/or Substance Use Disorder.
5. Currently pregnant, planning to become pregnant in the next 20 weeks, or breastfeeding.
6. Presence of a knee prosthesis.
7. Any significant illness, disease, or condition which, in the opinion of the Principal Investigator, may impact the ability to participate in the study or impact the study outcomes.

Allergies and Intolerances

1. Known hypersensitivity or previous allergic reaction to: Chondroitin sulfate, Maltodextrin, Mannitol, Magnesium Stearate, Silicon dioxide, Microcrystalline cellulose, or Talc.
2. Known sensitivity or intolerance to wheat or gluten.

General Compliance

1- Unlikely for any reason to be able to comply with the trial, or considered unsuited for participation in the study by the Principal Investigator.
