What is Seed
Seed is the microbiome science company that basically reinvented probiotics from the ground up and made every other probiotic brand look like they’re stuck in 2005. Think precision microbiome science meets sleek design, backed by actual clinical trials instead of marketing fluff. Their flagship DS-01 Daily Synbiotic isn’t just another probiotic; it’s a 24-strain powerhouse that combines probiotics and prebiotics in a patented capsule-in-capsule design that actually survives your stomach acid.
Founded by scientists who were frustrated with the Wild West probiotic industry, Seed partners with world-renowned researchers and has their products in clinical trials with major institutions. The DS-01 contains 53.6 billion AFU (Active Fluorescent Units), a more accurate measure than the industry-standard CFU, and targets everything from digestive health to skin health to immune function. Research published in Gastroenterology confirms that multi-strain probiotics can significantly improve gut function and overall health outcomes. What sets Seed apart? They use strain-specific research, meaning each of their 24 strains has clinical backing for specific health benefits. Plus, their sustainable packaging and commitment to transparency makes them the kind of company you actually want to support.
Why Seed Qualifies for HSA/FSA Eligibility
According to IRS regulations, probiotics can qualify as eligible medical expenses with a Letter of Medical Necessity under specific circumstances outlined in Publication 502.
IRS Publication 502 states that medical expenses are “the costs of diagnosis, cure, mitigation, treatment, or prevention of disease, and for the purpose of affecting any part or function of the body,” but “must be primarily to alleviate or prevent a physical or mental condition or illness.”
This means Seed probiotics can qualify for HSA/FSA reimbursement for preventing, managing, or reversing:
- Digestive disorders and gut microbiome imbalances – A systematic review in the American Journal of Gastroenterology found that multi-strain probiotics significantly improve digestive function and help restore healthy gut microbiome composition in patients with dysbiosis.
- Irritable bowel syndrome (IBS) – Research published in the World Journal of Gastroenterology demonstrates that specific probiotic strains effectively reduce IBS symptoms including bloating, abdominal pain, and irregular bowel movements.
- Immune system deficiencies – A meta-analysis in the British Journal of Nutrition found that probiotic supplementation enhances immune function and reduces the incidence and duration of respiratory infections by up to 47%.
- Antibiotic-associated digestive disruption – Cochrane systematic review confirms that probiotics prevent and reverse antibiotic-associated diarrhea, with multi-strain formulations showing the strongest protective effects.
- Inflammatory bowel conditions – Research in Alimentary Pharmacology & Therapeutics shows that certain probiotic strains help manage inflammatory bowel diseases by modulating gut inflammation and supporting intestinal barrier function.
- Skin conditions linked to gut health – A study in Beneficial Microbes found that probiotic supplementation improves skin conditions like acne, eczema, and rosacea through the gut-skin axis connection.
- Mood disorders related to gut-brain axis – Research published in Gastroenterology demonstrates that probiotics influence the gut-brain axis and can help manage symptoms of anxiety and depression by modulating neurotransmitter production.
- Chronic digestive inflammation – A study in the Journal of Clinical Gastroenterology found that probiotic supplementation reduces markers of intestinal inflammation and helps reverse chronic gut inflammation.
The key requirement is that your healthcare provider must document the probiotics as medically necessary for preventing, managing, or reversing your specific health condition – not just for general wellness. This documentation comes in the form of a Letter of Medical Necessity (LMN).
How to Assess Your HSA/FSA Eligibility For Seed
Traditional Route: Schedule an appointment with your primary care physician, discuss your digestive health conditions and probiotic needs, and request a Letter of Medical Necessity if probiotics are recommended as part of your care plan. This typically requires an office visit, potential wait times, and can cost $50-100+ depending on your insurance.

Our platform connects you with licensed healthcare providers who can evaluate your conditions remotely and issue the appropriate documentation if you qualify.

Frequently Asked Questions
Do other probiotics and gut health supplements qualify for HSA/FSA?
Yes! With the right medical documentation, you can use HSA/FSA funds for many gut health and digestive supplements.

Check out our complete vitamins and supplements guide for more options.
How does reimbursement work?
Most retailers do accept HSA/FSA cards directly. You’ll purchase your subscription with your personal card and then reimburse yourself. This means saving your receipts and uploading them along with your LMN to your HSA/FSA admin portal. With Crates Health, we simplify this process: upload your receipt and get one-click reimbursements all from our platform.
What is a Letter of Medical Necessity?
A Letter of Medical Necessity (LMN) is a document from a licensed healthcare provider that explains why a specific expense like your Seed subscription is medically necessary for preventing, managing, or reversing a diagnosed condition. It’s the official paperwork that proves your probiotic supplementation isn’t just for general wellness. Each LMN typically remains valid for 12 months from the date of issue.
Will my claim get denied?
With proper documentation, denials are rare. That said, every HSA/FSA administrator is different, and some may initially deny claims due to receipt format, LMN documentation, or unclear medical necessity. Crates Health supports you through any denials and makes sure you get reimbursed.
Can I use my HSA/FSA for Seed I already bought?
Unfortunately, no. Your LMN must be dated before the purchase date for it to be eligible for reimbursement. The IRS requires medical necessity to be established at the time of the expense, not after. But if you get your LMN now, then your next subscription charge or purchase will be eligible.
How long does it take to get an LMN from Crates Health?
Most users complete the Crates Health process in a few minutes. You’ll answer questions about your health conditions, and if you qualify, a licensed healthcare provider reviews your information and issues your LMN the same day. No appointments, no waiting rooms, no hassle.
