Is Metamucil FSA/HSA Eligible?

Yes, Metamucil is eligible for reimbursement with a Flexible Spending Account (FSA) or Health Savings Account (HSA).

Why Is Metamucil FSA/HSA Eligible?

Metamucil is FSA/HSA eligible because it is specifically designed to address medical conditions like occasional constipation and irregular bowel movements. Its active ingredient, psyllium husk, works by absorbing water in the digestive system, creating bulk, and promoting regularity. This targeted medical function aligns with IRS guidelines for reimbursable healthcare products.


The CARES Act of 2020 further ensures that over-the-counter (OTC) products like Metamucil can be purchased without requiring a prescription, making it easier to use FSA/HSA funds for this product. Additionally, Metamucil may provide secondary benefits, such as supporting heart health by lowering cholesterol levels, which are considered medical purposes under certain conditions.

  • Name of the provider

  • Date of purchase/service rendered (note that for services, they must be rendered within the plan year for FSAs)

  • Description of items/services rendered

  • Itemized list of products purchased with UPCs (if purchasing items at a retailer that doesn’t accept FSA cards or if using a regular credit card)

  • Total amount of purchase

What Other Fiber Supplements Are FSA/HSA Eligible?

In addition to Metamucil, other fiber supplements are eligible for FSA/HSA reimbursement if their primary purpose is to treat medical conditions like constipation or irregularity. Examples include:

  • Benefiber: A soluble fiber supplement that supports digestive health and helps with bowel regularity.

  • FiberCon: A bulk-forming fiber laxative that promotes natural bowel movements.

  • MiraLAX: A laxative designed to treat occasional constipation and improve stool consistency.

To qualify, these products must be used for medical purposes rather than general wellness or weight management. Supplements marketed for non-medical benefits are not eligible unless you provide a letter of medical necessity from a healthcare provider.
