20 HSA/FSA Eligible Supplements: What Qualifies & How to Save 30%

Most supplements are considered "general wellness" purchases, and general wellness doesn't qualify for HSA or FSA spending on its own. But that's not the whole story.

Under IRS Section 213(d), supplements can be HSA/FSA eligible when they address a diagnosed or diagnosable medical condition and a licensed clinician documents that need in a Letter of Medical Necessity (LMN). The supplement doesn't change, the documented medical rationale does. A protein powder marketed for general wellness doesn't qualify. The same protein powder recommended to address muscle wasting or nutritional deficiency can.

The critical distinction between an HSA/FSA eligible supplement and an ineligible supplement is purpose. A protein powder marketed as "general wellness" does not qualify. The same protein powder, recommended by a clinician to address muscle wasting, metabolic syndrome, or significant nutritional deficiency, may qualify. The supplement itself is the same. What changes is the documented medical rationale.

This is where a Letter of Medical Necessity (LMN) comes in. An LMN is a document signed by a licensed healthcare provider that connects a specific product to a patient's specific medical need. With an LMN on file, the purchase becomes a qualified medical expense eligible for HSA or FSA reimbursement.

The three-part test for supplement eligibility:

• It addresses a diagnosed or diagnosable medical condition (not general health improvement)
• A licensed clinician has documented the medical rationale in a Letter of Medical Necessity
• The product meets safety and quality standards appropriate for therapeutic use

In the LMN approval process, a licensed clinician evaluates each consumer's reported health history and needs based on their answers to a clinical intake survey. Common qualifying conditions include:

• Gut & Digestive Health: IBS, gut permeability, microbiome dysbiosis, chronic inflammation
• Immune Dysfunction: Immune vulnerability caused by treatment for chronic conditions or by the chronic condition itself
• Metabolic & Hormonal: Nutrient deficiency, hormonal imbalance, metabolic syndrome, insulin resistance
• Cognitive & Mental Health: Anxiety, chronic stress, HPA axis dysregulation
• Musculoskeletal & Recovery: Muscle loss, sarcopenia risk, joint inflammation, connective tissue repair
• Sleep & Stress: Chronic sleep disruption, adrenal fatigue, stress dysregulation

As noted above, you might be able to purchase certain supplements with HSA or FSA dollars. However, you might need a letter of medical necessity (LMN). An LMN is a formal document from a licensed healthcare provider that explains why a certain product, treatment, or service is necessary to treat, mitigate, or prevent a medical condition.

Certain health products and services may be eligible for qualified customers with an LMN issued by an independent practitioner when the item is used to address a specific medical condition.

Truemed* specializes in helping you maximize your HSA and other health-related benefits (such as an FSA):

• First, you can check whether a product or service is normally considered a qualifying medical expense or whether you might need an LMN.
• Complete a health intake survey that will be reviewed by an independent licensed clinician.
• Buy the item; either pay directly with your HSA/FSA card at checkout, or pay with a regular credit/debit card and seek HSA/FSA reimbursement afterward.
• The independent licensed clinician will review your medical history, and if you qualify, will issue an LMN. Truemed itself does not make eligibility determinations.
• Truemed also offers support in the event you get a denial of reimbursement and need to provide substantiation documentation.
