I try to be proactive regarding my health and the blood samples gave me all of the information I needed to update supplemental needs. These blood samples give you more information than a doctors CBC test.

I was given results and what the results mean and areas that need to be addressed. I plan to take this information and discuss with my PCP and cardiologist. I really liked learning all the supplements that may be helpful to me and in what amounts.
