Why PreviMedica?

You're unique. Your nutrition plan should be too.

Each member of our nutrition team is trained in functional nutrition and lifestyle strategies to guide you to optimal health.  Rather than use a “one size fits all” approach, we utilize advanced lab testing to help identify root causes of your health issues and personalize a nutrition plan that not only meets your unique needs, but is as realistic as possible for you to implement.

Client Feedback

The crew at Previmedica are tops in my book. The nutritionist Natali took her time with me, personalized a plan to obtain sensitivity free supplements and foods. Overall I am extremely happy with the staff and services they provided.

I highly recommend the Alcat test to anyone suffering from inflammation, as well as other diagnosed symptoms/diseases that are inflammatory in nature. This is absolutely the best thing I have ever done.

We highly valued our complimentary 1-month and are very appreciative of and grateful for Basilia's warm nature, matter-of-fact guidance, deep knowledge, quick and thorough responses and overall attentiveness...
