Short answer: most vitamins and supplements are not HSA eligible. They count as general health, not medical care.
But there are real exceptions. Here is the full breakdown.
The default: not eligible
A daily multivitamin you take for general wellness does not qualify. Neither does most of the supplement aisle.
The IRS rule is that an item taken to maintain general health is not a medical expense, even if it is genuinely good for you.
The exceptions that do qualify
| Item | Eligible? | Condition |
|---|---|---|
| Prenatal vitamins | Yes | Generally eligible without a letter |
| Glucosamine / chondroitin | Yes | Commonly accepted for joint conditions |
| A supplement to treat a diagnosed deficiency | Yes | Requires a Letter of Medical Necessity |
| Daily multivitamin | No | General health |
| Protein powder, greens, general wellness | No | General health |

The paperwork that turns a no into a yes
If a doctor recommends a specific supplement to treat a diagnosed condition, like iron for diagnosed anemia or vitamin D for a documented deficiency, it can qualify.
The document that proves it is a Letter of Medical Necessity. It names the condition and states that the supplement treats it.
Without that letter, a supplement that "could" be medical is treated as general health. The same letter rule can turn a wellness wearable into a qualified expense.
How to handle it at checkout
- ●Prenatal vitamins: keep the receipt, reimburse normally
- ●Doctor-recommended supplement for a condition: get the Letter of Medical Necessity first, then save it with the receipt
- ●Everything else: pay out of pocket, do not reimburse
The mistake to avoid
Do not reimburse a year of multivitamins because one bottle felt medical. An auditor reads "multivitamin" as general health by default.
If you want a supplement to count, the order is always the same: diagnosis, then letter, then receipt. Skip a step and it is not eligible.
