# Supplement Audit - East Austin 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, you’ll bring in every vitamin, herb, and powder you are currently taking. 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. Address will be provided upon booking. Location is near Airport Blvd & Oak Springs Dr. in East Austin. This is an educational and general wellness service; not medical diagnosis or treatment.
