Stem Cell Support Formula Study for Patients with Knee Osteoarthritis

Patients must be able to visit the clinic in Broomfield, CO to see if they are a candidate and for all study visits (evaluation and 2-month visit).

Our Research Team is conducting a study to understand the effects of the Regenexx Stem Cell Support Formula on joint health. Participants in the study will be randomly assigned to one of 2 groups, either to receive the real supplement formula or a placebo supplement. Patients will take 1 ounce (1 capful) of the liquid supplement provided for 2 months. Participants will keep a daily diary to document doses and pain medications taken. After taking the supplement for 1-month, participants will complete online surveys and have a check-in with someone from our research team. At 2-months, participants will visit with one of our research staff to complete another set of questionnaires and final study activities. They will also be told at that time whether they had been assigned to the real or placebo supplement. If in the placebo group, you will receive 2 real bottles of supplement at no cost.
