Phase 2 — Testing in a bigger group (up to a few hundred people) to see if the treatment actually works and is still safe.

What is this trial?

This trial is testing a treatment called PARAGON Novel Metabolic Regulator Formula (PNMR) to see if it can help people recover from Long COVID. The medication is designed to replenish nutrients that may be depleted by COVID-19 infection, helping your immune system and energy-producing cells work better. Researchers believe this approach may help reduce the wide range of symptoms that Long COVID causes.

Long COVID affects millions of people with lingering symptoms months after infection. Research suggests that people with Long COVID have depleted nutrient stores that prevent their immune system and cellular energy systems from healing properly. This trial exists to test whether restoring those nutrients can help your body recover.

Do you qualify?

You likely qualify if…

you are 19 years of age or older
you have a confirmed COVID-19 diagnosis from more than four weeks before starting the study
you have been diagnosed with Long COVID according to WHO criteria—meaning symptoms that started or continued at least three months after your initial infection and have lasted longer than two months
you have tested negative for COVID-19 for at least four weeks before enrolling
you are willing to follow the study's dietary and lifestyle recommendations and complete the required questionnaires and physical tests
if you are a woman who could become pregnant, you agree to use reliable contraception during the study

You likely don't qualify if…

you are pregnant, breastfeeding, or trying to become pregnant
you follow a vegetarian diet or cannot follow the study's dietary guidelines
you have taken high-dose vitamin D (5,000 IU or more daily) or zinc (50mg without copper) for four or more weeks in the month before starting the study
you are currently in another drug trial for COVID-19 treatment (unless the sponsor approves)
you have a known allergy to the formula or any of its ingredients

What participation looks like

If you enroll, you will take the medication as capsules by mouth, starting with a higher dose that you adjust downward over six weeks based on your symptoms and how your body responds. You will also receive specific dietary and lifestyle recommendations to follow during the study. You will complete questionnaires, keep a symptom diary, and undergo a physical walking test (called the 6-minute walk test) to help researchers measure whether the treatment is helping you recover.
