I decided to take Christa's advice and go to FDN. The course starts with our own lab work before working with clients. I didn't want to start the lab work until I was somewhat stabilized after the Gut Thrive program. When can I begin BioHealth lab work?

Congratulations on enrolling in FDN! The suggestion is to run labs on yourself 2 weeks after you're into Step 5, your 80/20 maintence and taking your transition phase supplements to get the most accurate barometer of progress and then even again in 4 months (as long as you eat clean) to see the difference that terraforming makes.
