You may be wondering...

What are HSAs and FSAs?

HSAs and FSAs were created for you to spend tax-advantaged dollars on approved products and services that support your health. Many employers offer these funds, which are saved in dedicated accounts.

Can I use my HSA/FSA funds to get reimbursed for fatty15?

Chances are, yes! We have partnered with Truemed, a team devoted to helping consumers use their HSA/FSA funds to get reimbursed for science-backed products (aka fatty15) that support long-term health.


How do I use my HSA/FSA funds to get reimbursed for fatty15?

Follow these three simple steps:


Purchase fatty15 as you normally would, with your usual credit or debit card.


Look for an email from fatty15 with instructions for how to get reimbursed with HSA/FSA funds, including a link to take a health survey to get qualified.


After completing the survey, you'll receive a Letter of Medical Necessity that you can share with your HSA/FSA administrator. Truemed will also provide instructions on how to get reimbursed for your fatty15 purchases.

It’s that easy!


  • Is fatty15 covered under an FSA/HSA reimbursement plan?

    Exciting news! Yes, fatty15 supplements are covered under FSA/HSA reimbursement plans, made possible through our partnership with Truemed.

  • How long does the approval process take for a customer to get a Letter of Medical Necessity?

    The qualification survey form is only a few questions. No live consultation with a doctor is required. If eligible, approval is instant, and Truemed will then provide a Letter of Medical Necessity via email within 24 hours.

  • How many Letters of Medical Necessity does a customer need to obtain?

    Each Letter of Medical Necessity can cover all orders of fatty15 over a 12 month period. Prior orders can be reimbursed subject to rules set by HSA/FSA providers.

  • How long does the Letter of Medical Necessity last?

    Each Letter is valid for 12 months before it needs to be renewed.

  • How do I get reimbursed for fatty15?

    Purchase fatty15 using your usual credit or debit card. Truemed will then provide the documentation, upon approval, to submit your reimbursement claim to your HSA/FSA provider. You can either submit claims individually or all at the end of the year.

  • Can I use my Letter of Medical Necessity for prior purchases of fatty15?

    You will have to check with your HSA/FSA insurance carrier. While we cannot comment on orders placed in the past, once qualified, we can promise that you can get reimbursed for future fatty15 orders.
