Are dietary supplements and vitamins taxable?

⚡ TL;DR

Dietary supplements and vitamins are taxable at the full rate in most states — they fall outside both food exemptions and prescription drug exemptions. California has historically exempted qualifying supplements; Illinois applies a reduced 1% rate. Products with a Nutrition Facts label versus a Supplement Facts label may be taxed differently in states that use label-based tests.

Dietary supplements occupy an awkward middle ground in sales tax: they’re neither food (in the exemption sense) nor prescription drugs. In most states, that means taxable at the full rate. For ecommerce supplement brands, state-by-state taxability mapping is more important than in almost any other product category.

Why supplements are typically taxable

Food exemptions in most states are defined narrowly, items sold primarily for human nutrition and home consumption. Supplements and vitamins are generally excluded from these definitions because:

They’re not consumed as a primary food source
They’re regulated under DSHEA as dietary supplements, not as food
Most state food exemption statutes predate the modern supplement industry and don’t explicitly include them

Prescription drug exemptions don’t apply either, supplements are sold over the counter and are not FDA-approved drugs.

State breakdown by approach

Taxable (full rate) — most states: Including TX, NY, FL, PA, OH, NC, GA, WA, TN, and most others. Supplements and vitamins are taxed at the standard rate.

Exempt or partially exempt: A smaller set of states treat supplements more favorably:

California: has historically exempted vitamins and dietary supplements meeting specific criteria
Illinois: applies the reduced 1% rate (not full 6.25%) to vitamins and dietary supplements alongside other drugs
Some SST states: the SST definition of “dietary supplement” creates a defined category that member states may treat differently, check each SST state’s treatment

State-specific edge cases:

Products marketed as “food” (protein bars, meal replacement shakes) may be treated as food rather than supplements in some states
Products with an FDA Nutrition Facts label vs. Supplement Facts label may be taxed differently in states that use label-based tests
Medical foods and products for specific medical conditions may be treated as exempt medical products in some states

Product type variations

Product	Typical treatment
Multivitamins	Taxable in most states
Protein powder	Taxable in most states; some states treat as food
Herbal supplements (capsules)	Taxable in most states
Protein/energy bars	Often treated as food if Nutrition Facts label; supplement if Supplement Facts
Meal replacement shakes	Varies significantly, often taxable
Prenatal vitamins	Taxable in most states; OTC, not prescription
CBD products	Highly variable and evolving by state

What supplement sellers should do

Build a state-by-state taxability matrix for your SKU types before configuring your tax engine
Use product tax codes from your tax software that match your specific product category, generic “supplement” codes may not capture state-level nuance
Monitor state guidance changes, supplement taxability is an active area of state revenue agency guidance
Don’t assume food exemptions apply to your product without confirming the state’s specific supplement definition

Frequently asked questions

Are dietary supplements taxable?

Yes, in most states. Dietary supplements, including vitamins, protein powders, herbal supplements, probiotics, and similar products, are typically excluded from both the grocery food exemption and the prescription medication exemption. They're treated as general tangible personal property and taxed at the full state rate. A minority of states exempt certain supplements based on label claims or regulatory classification.

Are vitamins treated as food or as medicine for sales tax purposes?

Neither, in most states. Vitamins and supplements fall into a gap category, they're not 'food' under food exemption definitions (which focus on items sold for human nutrition as a primary food source), and they're not 'medicine' under medication exemptions (which require prescription status or FDA drug classification). The result is taxability at the full rate in the majority of states.

Which states exempt dietary supplements?

A smaller number of states exempt certain supplements, sometimes based on FDA labeling (products regulated as dietary supplements under DSHEA) or on specific state statutory definitions. California, for example, has historically exempted certain vitamins and dietary supplements from sales tax. Illinois applies the reduced 1% food rate to non-prescription medications and vitamins. State-specific guidance is essential: the taxability landscape for supplements varies significantly.
