How to Download Your Raw DNA Data File (23andMe, AncestryDNA & MyHeritage)

If you've taken a DNA test with 23andMe, AncestryDNA, or MyHeritage, you're sitting on a goldmine of health information that goes far beyond ancestry reports. Your raw DNA data file contains hundreds of thousands of genetic markers — and with the right tools, you can use it to discover which supplements your body actually needs based on your unique genetics.

This guide walks you through downloading your raw data from each provider, step by step.

What Is a Raw DNA Data File?

When you take a consumer DNA test, the company analyzes hundreds of thousands of locations (called SNPs) across your genome. The raw data file is a text file containing all of those results — your genotype at each tested position.

Most testing companies give you access to this file for free. It's typically a .txt or .csv file, ranging from 5 MB to 30 MB in size. Once downloaded, you can upload it to third-party tools like GeneSupp to get personalized health and supplement insights.

Downloading from 23andMe

23andMe makes it straightforward to download your raw data, though the process involves an email verification step for security.

Step 1: Log in to your 23andMe account at 23andme.com.

Step 2: Click your profile icon in the top-right corner and select Settings.

Step 3: Scroll down to the 23andMe Data section and click View.

Step 4: You may be asked to re-enter your password or complete two-factor authentication.

Step 5: In the "Download Raw Data" section, click Submit Request.

Step 6: Check your email for a message from 23andMe with a download link. Click the link to download your raw data as a .zip file.

Step 7: Unzip the file. Inside you'll find a .txt file — this is your raw DNA data.

Important note: As of 2025, 23andMe has undergone significant changes. If you haven't downloaded your data yet, do so as soon as possible. The raw data file is yours by right, and having a local copy ensures you always have access to your genetic information.

Downloading from AncestryDNA

AncestryDNA also provides free access to your raw data file. Here's how to get it:

Step 1: Log in to your Ancestry account at ancestry.com or ancestry.ca.

Step 2: Click DNA in the top navigation menu, then select Your DNA Results Summary.

Step 3: Click the gear icon (Settings) on your DNA results page.

Step 4: Scroll down to find the Download Raw DNA Data section and click Download.

Step 5: You'll need to re-enter your password and confirm your identity.

Step 6: Ancestry will send a confirmation email. Click the link in the email to start the download.

Step 7: Your raw data will download as a .zip file containing a .txt file with all your genetic data.

The AncestryDNA file format is well-supported by most third-party analysis tools, including GeneSupp.

Downloading from MyHeritage

MyHeritage DNA also allows you to download your raw data, whether you tested directly with them or uploaded data from another provider.

Step 1: Log in to your MyHeritage account at myheritage.com.

Step 2: Hover over the DNA tab in the top navigation and click Manage DNA kits.

Step 3: Find the DNA kit you want to download. On the right side, click the three-dot menu (⋯) next to the kit.

Step 4: Select Download Raw DNA data from the dropdown menu.

Step 5: Confirm your identity by re-entering your password.

Step 6: Your raw data file will download as a .csv file.

Note: MyHeritage uses a CSV format with quoted fields, which some tools may not handle correctly. GeneSupp fully supports the MyHeritage format, including the quoted CSV structure.

What to Do With Your Raw Data File

Once you have your raw DNA data file downloaded, you can use it to unlock insights that go far beyond what your testing company shows you. Here are the most valuable uses:

Personalized Supplement Recommendations

This is where GeneSupp comes in. Your raw data contains information about gene variants that affect how you absorb and metabolize nutrients. For example:

• MTHFR variants affect how you process folate — you may need methylfolate instead of folic acid
• VDR variants affect vitamin D receptor efficiency — you may need higher doses
• BCMO1 variants affect beta-carotene conversion — you may need preformed vitamin A

GeneSupp analyzes over 50 gene variants in your raw data and gives you a personalized supplement plan based on your actual genetics. Try it now [blocked] or view a sample report [blocked] to see what it looks like.

Health Risk Awareness

Some third-party tools can analyze your raw data for health-related genetic variants, including those associated with conditions like celiac disease, lactose intolerance, and caffeine metabolism.

Extended Ancestry Analysis

Services like GEDmatch and DNA Painter can provide more detailed ancestry breakdowns and help you find genetic relatives across different testing platforms.

Privacy and Security Tips

Your raw DNA data is among the most personal information you possess. Here are some tips for keeping it safe:

1. Store your file securely — keep it in an encrypted folder or password-protected archive on your computer.
2. Be selective about uploads — only upload your data to services you trust with clear privacy policies.
3. Prefer client-side processing — tools like GeneSupp process your DNA data entirely in your browser, so your genetic information never leaves your device.
4. Delete when done — if you upload to a service, check whether they store your data and how to delete it.
