Does FSA cover protein powder?
Protein powder taken for general fitness or nutrition isn't a qualified FSA expense, but it can qualify when a medical provider recommends it to treat a diagnosed condition.
What flips the answer
- Covered when
A medical provider recommends it to treat a diagnosed condition and you have a Letter of Medical Necessity.
- Not covered when
You're buying it for general fitness, muscle building, or everyday nutrition.
IRS Publication 502 treats nutritional supplements taken for general health as non-qualified. Protein powder bought to build muscle, support a workout routine, or round out a diet is a personal expense.
A supplement can qualify only when a physician recommends it to treat a specific diagnosed medical condition — for example, to address a documented deficiency or support recovery from an illness — rather than for general well-being.
In practice, that means FSA administrators want a Letter of Medical Necessity tying the protein powder to a diagnosis. Without one, the default is that it's a general-nutrition purchase and not eligible.
