Hi, I'm Anthony, co-founder at Burst. AG1 is one of the most-asked-about supplement brands on Burst, and the eligibility framework is more nuanced than most people realize.
Short answer. Yes. AG1 (Athletic Greens) can be FSA or HSA reimbursable with a Letter of Medical Necessity when there's a documented nutrient gap or related medical context. The IRS treats AG1 as a supplement under Publication 502 and Notices 2006-69 and 2007-2: not eligible by default (multivitamins are the only default-eligible supplement category), but reimbursable when a clinician documents the medical context. The contexts that approve most consistently are IBS or gut dysbiosis, post-bariatric or post-surgical malabsorption, restrictive eating disorders in recovery, and immunocompromised states. Recurring AG1 subscriptions reimburse on a rolling basis while the LMN is current (12 months typical). Below is the framework.
If that already describes you, the request takes about three minutes and you can skip the rest of this guide.
What's eligible with an LMN
AG1 daily packets. The flagship greens powder.
AG1 travel packs. Same eligibility.
AG1 starter kit and accessories (bottle, scoop, vitamin D drops bundled with subscription) when on the same receipt.
What's not eligible
AG1 branded merchandise.
Gift subscriptions for someone without their own LMN.
Common reasons people get an AG1 LMN
Documented IBS or gut dysbiosis affecting nutrient absorption
Post-bariatric surgery malabsorption
Restrictive eating disorder in recovery requiring nutrient-dense supplementation
Post-antibiotic gut recovery where comprehensive micronutrient support is part of the plan
Immunocompromised contexts (chemotherapy, autoimmune, organ transplant)
Documented vitamin D, B12, or magnesium deficiency where AG1's broad-spectrum supplementation supports the deficit
Pregnancy and postpartum nutrient demands with documented suboptimal labs
A few common AG1 FSA/HSA pitfalls
Treating AG1 as a default-eligible multivitamin. AG1 is a comprehensive greens-and-supplement blend, not a basic multivitamin. The LMN is what creates eligibility.
Letting the LMN expire mid-subscription. The recurring subscription needs a current LMN. Refresh annually.
Submitting subscription receipts without the LMN attached. Plan admins want the LMN with each batch of receipts.
AG1 FSA/HSA FAQ
Is AG1 HSA eligible without an LMN?
AG1 is a supplement under IRS rules, not a default-eligible multivitamin. The LMN creates eligibility.
Does the AG1 subscription reimburse monthly?
On the same LMN as the initial purchase, yes. Recurring while the LMN is current (12 months typical).
Can I get an LMN for AG1 I already drank?
Per IRS guidelines, LMNs must be for purchases made on or after the LMN request date. The recurring subscription going forward can be covered.
Is the LMN fee itself FSA/HSA eligible?
Yes.
Stop paying full price for AG1
If you've got a documented nutrient gap context and you're already on AG1, the LMN turns it into pre-tax. Get yours from Burst in under 5 minutes.
