Are vitamins and supplements HSA or FSA eligible?

What the IRS says

IRS Publication 502 puts nutritional supplements, vitamins and herbal supplements on its list of expenses that aren't includible, because they're generally taken for ordinary good health. The exception: a medical practitioner recommends them to treat a specific diagnosed condition.

The IRS FAQ on nutrition and wellness says the same thing in one line: supplements count only if recommended by a medical practitioner as treatment for a specific medical condition diagnosed by a physician.

• Likely not eligible: a general multivitamin, immune or energy blends, protein powder, supplements for general wellness or performance.
• Possibly eligible: iron for diagnosed iron deficiency, vitamin D for a diagnosed deficiency, B12 for a diagnosed deficiency, or another supplement your clinician recommends for a diagnosed condition and documents.

How to make a supplement claim

1. Get the diagnosis. A clinician confirms the condition, often with lab work. For example, see vitamin D blood test or vitamin B12 blood test.
2. Ask for a letter of medical necessity that names the condition, the supplement and how long you should take it. Many plans have their own form.
3. Buy the specific product the letter names and keep the itemized receipt.
4. Submit or keep records. For an FSA, your plan administrator decides. For an HSA, you keep the records that show the expense qualified.

If an HSA withdrawal turns out not to be for a qualified medical expense, it's taxable and IRS Publication 969 says an additional 20% tax applies. A card that goes through at checkout doesn't settle the question.

What about special foods and medical foods?

The IRS is just as strict about food. Food or drink counts only if it isn't part of your normal nutrition, it's needed to treat an illness, and a physician substantiates the need. Even then, only the cost above what normal food would cost counts.

Lower supplement prices either way

Most supplements won't qualify, so price matters. A free Gabriel account pays cost-plus prices on supplements, and with Gabriel Core or Plus member prices are lower still. Examples:

The clinical portion of Core or Plus may be HSA/FSA eligible ($39 of Core's $49, or $69 of Plus's $89); the wellness and concierge portion is not. Gabriel can provide an itemized statement; check with your plan administrator or a tax advisor. Membership could affect whether you can keep contributing to an HSA (IRS Notice 2026-5), so ask a tax advisor.
