Two is Better Than One.

Join our referral program and become an advocate for patients suffering from serious diseases and potentially help further microbiome research.

GoodNature donors commit to donate daily for 6 months or more and typically live within 20 minutes of a GoodNature donation center.

As an advocate in our referral program, you help educate and identify donors who are interested in making that commitment.

Get paid $100 if your referral completes three accepted donations at a center.

Be Someone’s Hero, Refer GoodNature a Donor

You or someone you know could help make a positive impact in the lives of patients. Here are the facts:
  • C. diff infection is a leading healthcare-associated infection in the U.S. Link image
  • Approximately 1 in 6 people who are infected will get it again in the subsequent 2-8 weeks.
  • Infection is estimated to cause almost half a million illnesses in the United States each year, and an estimated 29,300 deaths. Link image
Here’s the good news: your (or your friend’s) gut microbiome could potentially help be a part of the solution!
