Joi: Recommended by Kirstin Czernek
Joi: Recommended by Kirstin Czernek
Kirstin's favorite way to get blood work done

“As a mother of four, I need to be in tuned with my body and Joi offers deep dive blood diagnostic labs that allow me to supplement with precision.

No more guesswork. Blood work is super easy and quick. Joi can send a phlebotomist to your home for the blood draw, or you can go to a draw station. A week later, a clinician from Joi will go over your results with you. I do the comprehensive labs every 6-12 months and would recommend it to everyone.

Joi can then prescribe customized supplements based on your deficiencies. Not only did I see my biomarkers improve, I know I’m taking exactly what my body needs for better performance and better day-to-day life.”

What does Joi help with
Get An In-Depth Blood Analysis & Supplement Recommendations Based On Your Biomarkers

Choose between 3 different blood panels that have 44-74 biomarkers analyzed. We recommend choosing the blood panel that measures every biomarker you’re looking to optimize.

From there, you can either have a phlebotomist come to your house or choose from our CLIA & CAP certified lab partners, who have over 2,000 convenient locations with walk-ins and appointments available.

After you get your lab results, your virtual Joi provider will guide you through all the recommended changes to get you feeling your best-inside and out!

As far as improving your biomarkers, you can either take that into your own hands, or you can trust Joi, as we have high-quality, clinically dosed supplements that can help improve each and every one of your biomarkers.

Biological Age
Chronological Age VS. Biological Age

Chronological age is simply how long you’ve lived, while biological age measures how your body is aging at a cellular level. It’s a better indicator of your risk for age-related conditions like type 2 diabetes, heart disease, cancer, dementia, and kidney failure.

At Joi, we use 9 key biomarkers to determine your biological age, or “DNAm PhenoAge,” giving insights into your liver, immune system, inflammation, kidney health, and metabolism.

With your results, we can create a personalized plan to improve your physical and mental health, helping you optimize your biological age. Discover your biological age with Joi’s Advanced or Comprehensive lab!

Your Questions Answered
What is Joi?

Joi is a national telehealth provider that solely focuses on optimization and hormones.

What is precision medicine and “smart” supplements?

Precision medicine refers to the collection and analysis of biomarkers to see which areas you are deficient in to allow us to optimize your health. “Smart” supplements refer to specific supplements that will increase biomarkers that you are deficient in.

How does Membership and Subscription work?

The subscription is $99 a month. You are able to cancel the subscription at any time.

Is it truly customized off of my biomarkers?

Yes. Supplement recommendations are based off of lab results conducted during the blood draw. The results are then parsed with AI with an algorithm designed to offer the best supplements that will optimize your health – specifically tailored to you.

How long does the process usually take?

Blood work will take about 7 days to fully process. Once you meet with a wellness coach, supplements orders can take up to 10 days to process and 2 for shipping.

Which biomarkers and labs do you offer?

We offer 3 unique panels which you can read about here.

What will I find in my daily smart supplements?

The smart supplements come in a daily pack with 30 packs total. Each pack will come with the specific smart supplements for you to take on a daily basis.
