Test your PFAS levels at home. Meet with an independent physician. Start treatment if it’s right for you. Retest to see how your levels have changed.
PFAS persist in your body for years because your gut and liver accidentally recycle them. New research suggests certain medications may break this recycling loop so you excrete PFAS rather than accumulating them.
When researchers analyzed 50,000+ health records, they found something surprising: people taking certain common medications had significantly lower PFAS levels than expected, even though that wasn’t why they were taking them.
Read the study →The first controlled trial tested these medications' ability to reduce five different PFAS compounds. Treatment reduced all five types of PFAS, with levels of one particularly dangerous compound (PFOS) dropping 60% more than controls in just 12 weeks.
Read the study →Firefighters face some of the highest PFAS exposures of any group. This study showed medication effects even in high-exposure cases: firefighters’ PFOS half-life dropped from over 7 years to just 1.2 years, substantially reducing body burden.
Read the study →An independent Swedish cohort from a PFAS-contaminated town reported similar results: these medications reduced PFOS levels by nearly 40% in one quarter. The control group during the same period? Just 2%.
Read the study →One simple at-home fingerstick test tells you where you stand
Your kit ships free to your door. A quick fingerstick measures the PFAS circulating in your blood and establishes your baseline. Complete it at home, return it in the prepaid mailer, and get your results back with full context: each compound against published reference ranges, plus your Tare Score™ to track over time.

A consultation with a physician to review your results and confirm the path forward
Once you enroll, we connect you to an independent physician familiar with PFAS and treatment options. They’ll walk you through what your numbers mean, review your exposure history and medical context, and help determine if treatment makes sense for you.
One initial consult, three months of supervised care
If your independent physician deems medication appropriate, your treatment will ship directly to your door. Free side effect support is included. Throughout your three months, your physician is reachable whenever you have a question.
We're a medical service, not a pill mill. If your physician doesn't think medication is the right fit, your first month's $169 is refunded in full.
A second PFAS test shows how your levels have changed
Same fingerstick test, same prepaid mailer. You’ll see exactly how your PFAS levels have changed, measured against your baseline.
Discuss your results and priorities with your physician
You have a final consultation with your physician to walk through your results. Based on your data and goals, you and your physician decide whether more treatment makes sense.
We're opening the Tare program to a limited founding group this fall. Joining is free, puts you first in line, and gives you discounts when you start.
Joining the waitlist is free. There’s nothing to pay today and no obligation to pay in the future, but you’ll be first in line when we launch.
You're on the list
Congratulations! You're on the initial cohort list. We'll follow up soon!
