# Supplement Audit - Virtual with Shayla Cristie

> You’re investing good money into your daily supplement routine, but do you actually know which ones your body loves and which ones it’s rejecting? Even the highest-quality supplements can cause a stress response if they aren't right for your unique physiology right now. In this focused session, we'll meet via Google Meet while you have every vitamin, herb, and powder you are currently taking in front of you. Using muscle testing, we will test each product directly against your body so you can stop wasting money on products that aren't working for you. This is an educational and general wellness service; not medical diagnosis or treatment.
