Glad to hear it, Galina. We’re happy your experience with Function was smooth and positive. Thanks for sharing!
I had an excellent experience with Function Health. From start to finish, their customer service was outstanding. The staff was responsive, professional, and very understanding, making the entire process easy and stress-free. I was very impressed with the detailed health insights I received. The comprehensive testing gave me a much clearer understanding of my overall health and identified areas I can focus on to improve my long-term well-being. The results were easy to understand and provided valuable information that I can discuss with my healthcare provider. If you’re looking for a proactive approach to your health with exceptional customer service and meaningful, in-depth health information, I highly recommend Function Health.

Thank you for the kind words, Stephanie. We’re glad you’ve found the experience well organized and value the results and follow-up insights. We appreciate you sharing!
Mid-year labs were mistakenly ordered at 3 months. The advanced cardiac and metabolic labs were supposed to have been ordered. Function health did not take ownership of their mistake. This is not good medicine and not good business.

We're sorry to hear this was your experience. This isn't the experience we aim to provide. Our team previously addressed your concerns directly. If there's anything further we can help with, please reach out to us at [email protected], and we'll be happy to assist.
I love having all of the in depth knowledge and realistic recommendations about supplements to take and foods to avoid. All of the requirements for bloodwork were a surprise, and will be harder to do during a time of year with more strict routine.
