ArmDescriptionAssigned Intervention
Experimental
Magnesium Citrate plus a Probiotic Arm:
Participants assigned to the magnesium citrate plus a probiotic arm will receive 1 bottle of magnesium citrate 296 mL PO once to be taken within a 4-hour period, (about 10 oz.). Because magnesium citrate remains within the intestinal lumen, a second bottle can be provided if there is limited bowel movement. Patients will be asked to take 2 capsules of probiotics twice daily for six days or until discharge, whichever is earlier.
  • Drug: Magnesium Citrate plus probiotic
    296 ml magnesium citrate
Placebo Comparator
Placebo
Participants randomized to the placebo arm will receive matching placebo 296 mL PO once to be taken within a 4-hour period, (about 10 oz.) and 2 cellulose capsules twice daily for six days or until discharge, whichever is earlier. The placebo will be flavored to match the taste of the interventional arm.

Detailed Description

We are conducting an investigator-initiated, single center, blinded, placebo-controlled, randomized clinical trial evaluating magnesium citrate combined with a probiotic for the treatment of adults hospitalized with COVID-19. Patients, treating clinicians, and study personnel will all be blinded to study group assignment. This research study is being done to determine if taking oral magnesium citrate and a probiotic will improve the outcome of adults hospitalized with COVID-19. In this study, half of the participants will receive magnesium citrate plus a probiotic and half will receive a placebo randomized 1:1. You will be placed in one of these 2 groups randomly, like the flip of a coin. The investigational arm will receive one 10 oz. bottle of magnesium citrate to drink once and 2 oral probiotic capsules to be taken twice a day for 6 days. We will also collect a blood sample on Day 1 and Day 7 for CD4+ and CD8+ evaluation and will be collecting data on each participants COVID-19 infection progression during hospitalization. Assessments for this study will be done on day 7 and day 29 if the participant is still hospitalized at those time points. If they have been discharged from the hospital before these assessments, we will do these by phone. Each participant will also be contacted at 3 months to assess how they are doing. There will be no compensation for taking part in this study.
