Does FSA cover vitamins?
General-health vitamins and supplements aren't FSA-eligible under IRS rules — the same restriction that applies to HSA funds — though supplements a doctor prescribes for a diagnosed condition can qualify.
What flips the answer
- Covered when
A doctor prescribes the vitamin or supplement for a diagnosed condition or deficiency, typically documented with a Letter of Medical Necessity.
- Not covered when
The vitamin or supplement is for general health, energy, or wellness with no diagnosed condition behind it — the common case.
- Not covered when
The LMN paperwork isn't filed and substantiated within your FSA's plan year — unlike an HSA balance, an FSA doesn't roll over indefinitely to fix this later.
IRS Publication 502 excludes vitamins and supplements taken for general health or wellness, since they don't treat, cure, mitigate, or prevent a specific diagnosed condition. This rule is identical for FSA and HSA dollars, because both draw on the same IRS-qualified-expense list.
The exception is condition-specific: a doctor-prescribed supplement for a diagnosed deficiency or condition — prenatal vitamins during pregnancy, or a supplement tied to a documented nutrient deficiency — can qualify, usually with a Letter of Medical Necessity on file.
Where FSA differs practically from HSA: FSA funds are use-it-or-lose-it, with at most a small grace period or limited carryover depending on the plan. If you're trying to use a supplement purchase to draw down an FSA balance, the LMN paperwork needs to be filed and substantiated before your plan year's deadline — there's no rolling balance to fall back on the way there is with an HSA.
FSA elections are also employer-owned and fixed for the plan year, so you can't decide mid-year to add a supplement expense and adjust your contribution the way you might plan HSA contributions — the LMN documentation has to be sorted within the plan year you intend to claim it.
