Immediate rule: solid oral supplements (tablets, capsules) are permitted in both cabin and hold; liquid supplements follow the 3-1-1 carry-on limit (maximum 100 ml / 3.4 fl oz per container). Powdered products larger than 12 oz (≈350 mL) may trigger additional screening and, for some international departures, will be required to travel in hold baggage or be declared at security checkpoints.

Documentation and restricted ingredients: keep original labeling, purchase receipts and any physician’s letters for prescription-only items. Ingredients such as CBD, pseudoephedrine, certain sleep aids and some injectable formulations are restricted or prohibited in many countries; possession without prescription or declaration can lead to seizure, fines or arrest. Treat a supply exceeding a typical personal-use amount (common guideline: up to a 90‑day supply) as a red flag and bring supporting documents.

Packing tips for aircraft hold: place containers in sealable plastic bags, pad with clothing inside a hard-sided suitcase, and use desiccant packets for moisture-sensitive capsules. For temperature-sensitive goods (probiotics, live cultures, refrigerated injections) keep in cabin with an insulated cooler and gel packs; if dry ice is needed for frozen items, confirm airline limits and labeling requirements before travel.

Action checklist before departure: verify departure and arrival country customs rules and airline policies online or by phone; review the relevant aviation security website for powder and liquid limits; carry prescriptions and receipts in hand luggage; declare large quantities at customs when required. Failure to verify local regulations is the most common cause of seizure or denied entry.

Storing dietary supplements in aircraft hold: practical rules

Keep prescription and temperature-sensitive supplements in cabin baggage in original, labeled containers with a physician’s note; reserve non-critical quantities for stowage in the aircraft hold only after confirming destination and airline rules.

Screening and regulatory limits

Solid tablets and capsules are allowed in both cabin and aircraft-hold baggage by most regulators. Powdered supplements carried through cabin screening that exceed 12 oz (350 mL) may require secondary inspection and could be denied carriage into the cabin. Liquids in cabin follow the 3.4 oz (100 mL) single-container limit; larger volumes belong in hold baggage. Verify customs restrictions for herbal extracts, products containing animal derivatives, or controlled substances–some countries require permits or outright prohibit import.

Packing, documentation, and preservation

Keep items in original packaging with visible ingredient lists and dosage instructions; store scanned copies of labels and prescriptions in cloud storage and on a phone. Place pills in labeled zip-lock bags inside a hard-sided case to prevent crushing and theft. For refrigerated formulas (probiotics, certain oils), transport in the cabin inside an insulated pouch with frozen gel packs to avoid freeze/thaw damage in the hold. For injectable preparations, carry a prescription and a clinician’s note and confirm syringe rules with the airline before travel.

Limit cabin carriage to a 7–14 day supply and move surplus to the aircraft hold only when clearance is confirmed; declare restricted items on arrival documents when required.

Airline and TSA rules for carrying supplements in hold baggage

Pack supplements in original, clearly labeled containers; keep prescription items in carry-on for accessibility and inspection documentation.

TSA-specific requirements

  • Solid tablets and chewables: permitted in both carry-on and hold baggage with no federal quantity limit; items may be opened for inspection by Transportation Security Administration officers.
  • Powdered products: containers larger than 12 oz (350 mL) in carry-on are subject to enhanced screening and may require separate inspection; powders of any size are generally allowed in hold baggage but can be screened or removed if suspicious.
  • Liquids, gels and oil-based supplements: carry-on containers limited to 3.4 oz (100 mL) per item and must fit inside one quart-sized, resealable bag; larger volumes are allowed in hold baggage but flammable aerosols and certain pressurized containers may be restricted under airline hazardous materials rules.
  • Prescription formulations: allowed in both compartments; carry original prescription labels and a physician’s note if medication is controlled or requires special justification.

Airline policies and international customs

  • Individual carriers may impose additional limits on aerosols, large-volume liquids and certain powdered substances–consult the airline’s hazardous materials / prohibited items page before travel.
  • Some countries prohibit or require permits for specific ingredients (examples: certain herbal extracts, melatonin, stimulants, anabolic agents); verify destination import rules with customs or embassy resources ahead of departure.
  • When transferring between carriers or on international itineraries, expect secondary inspection and possible seizure if ingredients conflict with local laws; retain receipts and ingredient lists to support declaration.

Packing recommendations:

  1. Keep at least a portion of prescription supplements in carry-on with original labels and written dosing instructions.
  2. Seal powders and loose tablets in leakproof plastic bags and cushion glass bottles inside suitcases to prevent breakage.
  3. Photocopy or photograph prescription labels and receipts and store copies in email/cloud for quick access during inspections.
  4. Before departure, check both TSA guidance and the specific airline’s prohibited/hazardous items page; when in doubt, contact airline customer service or the embassy of the destination country.

Packing and labeling tips to avoid inspection or disposal

Keep supplements in original, factory-labeled bottles with manufacturer name, product name, ingredient breakdown, dosage per unit and lot/expiration information clearly visible.

Labeling steps

Photocopy and digital backup: photograph front and back labels and save copies in email or cloud; print one copy and place inside suitcase. Inventory sheet: create a short list (product name, active ingredient, quantity, purchase date) and tuck that list into a zipped compartment. Translations: for international itineraries, add a brief translation of active ingredient names into the destination language(s) or the closest scientific (INN) name.

Packing technique

Use original containers whenever possible; if decanting is unavoidable, transfer into clear, resealable plastic bags labeled with product name and net weight, then seal with tamper-evident tape. Place containers together in one central compartment of the suitcase surrounded by soft clothing to cushion and keep items in view on X‑ray. Avoid opaque metal tins or unmarked pill boxes that obscure identification. Keep prescription supplements accompanied by clinician letter and a copy of the prescription or pharmacy label in carry-on and inside the hold bag.

Limit transported quantity to a personal-use amount (common guideline: ninety days’ supply or less) and include purchase receipts to substantiate quantity. For powders and bulk supplements, ensure total weight is shown on the label or a printed note; loose powders should be avoided. If customs declaration is required at destination, declare any items containing controlled active ingredients and retain proof of purchase to reduce likelihood of seizure or disposal.

Powdered supplements: declaration, size limits, and screening

Declare powdered supplements larger than 350 mL (12 fl oz) at the security checkpoint; retain original sealed containers with visible labels and proof of purchase for inspection.

For cabin carriage, U.S. Transportation Security Administration guidance sets a 350 mL (12 fl oz) screening threshold: quantities above that are subject to enhanced screening and may be refused for cabin transport. Many non-U.S. airports follow a similar cutoff, while some carriers or countries require bulk powders to travel in the aircraft hold.

Security procedures commonly applied to powders: X-ray examination, manual inspection, and explosive trace detection (swab) tests. Agents may ask to open containers, transfer contents to a clear screening tray, or destroy material if testing is inconclusive. Unlabeled or loose powders increase the chance of destructive disposal.

Packing and documentation checklist to reduce inspection and loss:

– Keep products in manufacturer packaging with ingredient list visible.
– Carry printed receipts and product specification or manufacturer web page screenshots.
– Place containers inside one clear resealable bag for quick removal at checkpoints.
– Label any decanted portions with product name, strength, and date; avoid loose bulk in opaque containers.
– Accept that oversized quantities may have to be moved to the aircraft hold or surrendered.

Authority / Region Typical cabin threshold Typical screening action
TSA (United States) 350 mL / 12 fl oz Enhanced screening for >350 mL; may be refused for cabin carriage
EU airports (varies by country) Often ~350 mL; local variation Extra screening; some airports require bulk powders stowed in hold
CATSA (Canada) 350 mL / 12 fl oz (guideline) Additional screening; carry documentation to speed process
Other international carriers Varies – check carrier/airport May require stowage in aircraft hold or deny cabin carriage

When transporting non-edible powders for equipment or household use, consult product guidance; for example, see best filler for umbrella base for recommended materials and packaging practices.

Will airline-cargo temperature, pressure, or rough handling damage supplements?

Keep heat- and moisture-sensitive supplements in a carry-on bag; standard tablets and many hard capsules typically tolerate transit in the aircraft cargo compartment if packaged and sealed, while probiotics, fish‑oil gels, effervescent tablets and unsealed powders need extra protection or cabin carriage.

Temperature: most manufacturers specify “controlled room temperature” (15–25 °C) and recommend avoiding prolonged exposure above ~30 °C. Short periods above that (a few hours) accelerate degradation but often won’t render a product useless; prolonged exposure (days at 30–40 °C) reduces potency, increases rancidity in oils, and speeds loss of probiotic viability. Freezing seldom causes chemical breakdown for solid tablets but can cause condensation and cracking in tablets or capsules when thawed.

Pressure: typical pressurized passenger aircraft maintain cabin-equivalent pressure near 75–80 kPa (≈6,000–8,000 ft). That pressure change does not chemically harm solid supplements, but trapped air in partially filled bottles can expand and force leaking if caps are not airtight. Vacuum-sealed blister packs and factory-sealed bottles usually remain intact.

Mechanical stress: checked cargo sees more tipping, stacking and impact than the cabin. Fragile containers (glass), blister strips with thin foil, effervescent/chewable tablets and large single-dose softgels are most vulnerable to crushing or rupturing. Tablets in bulk pharmacy bottles can get crushed unless placed in a hard-sided case and cushioned.

Packing recommendations for protection: keep solids in original, heat-stable sealed packaging or in rigid plastic pill tubes; add silica desiccant for hygroscopic powders and tablets; wrap glass bottles in soft clothing and place inside a padded, hard-sided case; remove excess air from bottles for liquids and use leakproof caps plus sealing tape; double-bag powders in durable zip bags to contain spills and reduce moisture ingress.

Special-case guidance: refrigerated probiotics and some live‑culture products should travel in a temperature-controlled container or be carried onboard with ice packs to maintain recommended storage ranges; concentrated fish‑oil or krill oil capsules benefit from cool storage and light-blocking opaque bottles; powdered supplements sensitive to clumping perform better in single-dose sealed sachets.

Final practical checks before travel: verify storage instructions on labels, reseal or transfer to airtight, impact‑resistant containers, include desiccant, and choose cabin carriage for items explicitly requiring refrigeration or rapid potency retention.

International customs, prescription requirements, and documentation to bring

Keep prescription-only dietary supplements in original pharmacy containers, accompanied by a physician’s letter and a printed prescription; declare them at the border and present documentation when requested.

Required documents: original container with pharmacy label showing passenger name, generic drug name, dosage and prescribing physician; a dated letter on clinic/hospital letterhead stating medical indication, daily dose, and total quantity carried; a printed copy of the prescription (Rx) with prescription number; photocopies of passport ID page and travel itinerary. Provide certified translations into the destination language when English is not commonly used.

Controlled or prescription-status ingredients: substances frequently restricted include narcotics, benzodiazepines, opioids, codeine-containing formulations, pseudoephedrine, stimulants (ephedra, DMAA), certain hormones, and psychoactive cannabinoids (CBD/THC). Many countries in the Middle East and parts of Asia maintain zero-tolerance lists and will seize or detain products containing those ingredients without an import permit.

Quantity guidance: most customs authorities accept a reasonable personal supply–commonly defined as up to a 90-day (three-month) quantity–provided documentation is present; quantities substantially above that (for example, >90 days or large bulk packages) may require an import licence, commercial invoice, or attract scrutiny as commercial importation. For controlled medications, some authorities restrict to a 30-day supply unless a permit is obtained in advance.

Permits and pre-clearance: verify destination health authority rules before travel. Examples of processes to check: national therapeutic goods regulators or drug control agencies, embassy consular advice pages, and customs websites. When a permit is required, allow several weeks for approval and carry the permit certificate with the product.

Herbal, plant-based and powdered formulations: bring the original manufacturer label with full ingredient list, batch number and manufacturer’s contact; supply a Certificate of Analysis (COA) where available. Some countries treat plant-derived products as agricultural imports and may require phytosanitary certificates or prohibit specific botanical species altogether.

When carrying prescription-only items that include controlled substances, declare them on arrival forms and present documentation proactively to customs officers. Maintain both printed and digital copies of all paperwork in accessible carry items so inspection does not require accessing stowed baggage.
