Is Magnesium citrate FSA/HSA eligible?
Yes. Magnesium citrate used as an over-the-counter saline laxative is FSA and HSA eligible with no prescription.
Why
What the IRS rules say
As a saline laxative, magnesium citrate is an OTC drug that treats constipation, so it qualifies under the CARES Act. Note this covers the laxative product, not general magnesium dietary supplements taken for wellness.
Based on CARES Act (2020), Section 3702.
How to pay with FSA/HSA
You have two options. Swipe your FSA or HSA card at checkout and it comes straight out of your benefits, or pay your own way, keep the receipt, and file for reimbursement. Either works.
Good to know
Common questions
Is a magnesium supplement also eligible?
Not automatically. General magnesium supplements taken for wellness are treated as dietary supplements and usually need a Letter of Medical Necessity. The saline laxative form is eligible on its own.
