Habit Core personalized nutrition plans hero

Habit Core

Understand your unique nutritional needs based on your biology. You'll receive your Nutrition Test Results and a Personalized Nutrition Plan based on your results.

Already have 23andMe or
AncestryDNA test results?

The Habit kit tests your metabolism, DNA and body metrics. If you already have DNA results from 23andMe or AncestryDNA, we won’t need to retest your DNA and you can save $100.


We accept HSA/FSA payments. Check your plan for coverage as individual plans will vary.

*Currently not available in NY, NJ, and RI. Habit is not available for sale outside of the United States.

Common Questions

We do have a few restrictions. Currently you must be 18 or older to purchase. Additionally, Habit programs are not yet available to people who are pregnant, lactating, or diabetic. And, there are just a few states we can't ship to yet. However, we're working on creating more programs for more customers. Join our waitlist and we'll contact you as soon as we have services available for you

Depending on your location, your kit will be delivered within 15 business days of when you order. Once your kit is shipped, you'll receive a confirmation email with a tracking number (we'll send the email within 24 hours). If you don't receive the email, please check your spam or promotions folder.

If you have results from AncestryDNA or 23andMe, you can import your wellness-related genetic data instead of completing another DNA test. Learn more about Habit Core with DNA Import.

If you're not an AncestryDNA or 23andMe customer but would like to use your own data, please stay in touch. We're working toward different options for people who already have their nutrition-related blood and genetic data.

Please note that an essential part of the test is drinking the Habit Challenge® Shake, which is unique to Habit. The shake is used to challenge your metabolism and understand how your body responds to carbs, fats, and protein. Click here for an explanation of what the shake is and why you need to drink it.

You'll complete the test at home, and the entire process spans about 2.5 hours (which includes some in-between time where you're free to kick back and relax).

After an overnight fast, you will:

  • Measure your core (a.k.a. waist) using the provided tape measure.
  • Collect DNA samples with cheek-swabs.
  • Drink the Habit Challenge® Shake, which is used to test how your body handles carbs, fat and protein.
  • Perform finger pricks to gather drops of blood (one time before you drink the shake, two times after you drink it).
  • Weigh yourself on a scale.
  • Answer an online questionnaire to give us information about yourself.

This gathers all the information we need to personalize your nutrition plan. Click here for a sneak peek of what your results and nutrition plan will look like.

After you mail your samples, please allow up to 6–8 weeks to receive your results, which will include your personalized nutrition plan.

It may be possible to pay for Habit Core with your health savings account (HSA) or health flexible spending account (FSA). Check your plan for coverage as individual plans will vary.

In discussing plan coverage, you can tell your provider that the test is taken at home with blood and saliva samples and analyzed by our 3rd party CLIA/CAP accredited partner lab. The lab measures and analyzes the following:

Blood Sample:

  • Post-meal glucose – 30 and 120 minutes
  • Fasting glucose
  • C-peptide – 30 and 120 minutes
  • Fasting triglycerides
  • Post-meal triglycerides – 30 and 120 minutes
  • Total Cholesterol
  • LDL cholesterol
  • HDL cholesterol

Saliva sample:

  • Caffeine sensitivity gene variant
  • Lactose intolerance gene variants
  • Cholesterol balance gene variants
  • Blood sugar management gene variants
  • Triglyceride balance gene variants
  • Weight gain gene variants
  • Gene variants related to blood pressure
  • Gene variants related to omega-3 fatty acid production
  • Gene variants related to vitamin D levels
  • Gene variant related to folate metabolism

Contact your insurance provider to discuss coverage. At-homes tests, like the Habit Nutrition Test included in Habit Core, are not typically covered by insurance. They may, however, be paid for with an HSA or FSA account. See Can I use my HSA or FSA account to pay for a test?
