Capsules and tablets
A factory-sealed bottle in a padded mailer or small box is enough. Fill any air space with paper or foam so bottles do not rattle; loose bottles knock caps off in transit.
Yes. USPS, UPS, FedEx and DHL Express all treat plain vitamins and dietary supplements as ordinary parcels. USPS Publication 52 section 453 puts them in the over-the-counter category, which is mailable so long as the sender meets other federal, state and local law; a small number of other OTC medicines carry the same DEA-mailer restriction as prescription drugs, but a standard multivitamin, protein powder or fish-oil capsule is not among them. The rules that catch people out are for prescription medicines and hemp-derived products, not for standard supplements. Read on for a clean packing method and the two categories that actually have restrictions. Sources dated 2026-08-23.
Is it OTC? Is it a plant-derived item on the FDA list? OTC yes, plant-derived requires paperwork.
USPS Publication 52 section 453 covers controlled substances and drugs. Its OTC clause reads that nonprescription medicines — the publication names patent medicines, aspirin, antiseptics, cold remedies and diet pills — are mailable, subject to the mailer meeting all applicable federal, state and local law. Vitamins and dietary supplements fall in that same OTC bucket by the same logic; they are not prescription items and not controlled substances.
| Carrier | OTC vitamins | Prescription drugs |
|---|---|---|
| UPS | Accepted as ordinary parcels; not listed among prohibited or restricted items | Not covered either way by the prohibited and restricted lists; a US sender is still bound by the federal and state rules on who may dispense and ship prescription medicine |
| FedEx | Accepted as ordinary parcels (per FedEx, read 2026-08-11) | Accepted from authorized entities; controlled substances require additional paperwork (per FedEx, read 2026-08-11) |
| DHL Express | Accepted as ordinary parcels; not listed among restricted items on DHL's US shipping FAQ. Note destination country's import rules on supplement content | Not covered either way by the FAQ read here; the same federal and state rules on who may dispense and ship prescription medicine apply |

Protein and greens tubs need a snug outer box, not a mailer. Add corner cushion on all six faces so a drop cannot split a plastic tub at the seam.
Bag each glass dropper in a resealable pouch, wrap with bubble, box rather than mail. USPS accepts liquid dietary supplements; the packaging has to prevent a leak reaching another mailpiece.
A cold-weather note: fish-oil softgels tolerate freezing but liquid probiotics and some tinctures do not. Ship those between spring and autumn or add an insulated pouch during winter.
Most confusion about mailing supplements comes from products that are not really supplements at the postal or carrier level.
Yes. USPS treats vitamins and dietary supplements as over-the-counter items under Publication 52 section 453, which permits nonprescription medicines through the mail on the condition that the mailer meets all applicable federal, state and local law.
Yes. Neither carrier restricts standard vitamins and dietary supplements. Both restrict prescription medications, controlled substances and some hemp-derived products; a plain multivitamin, protein powder or fish-oil capsule is an ordinary parcel.
Capsules and tablets in a sealed bottle ride well in a bubble mailer or small box. Liquid drops and tinctures need a leakproof outer bag and cushioning to survive a drop; glass droppers benefit from a box rather than a mailer.
The FDA labeling that applies to a dietary supplement is a product-package requirement, not a mailpiece one. The shipping label carries the same information any other parcel does; the inner supplement label already meets FDA's Supplement Facts rules.
USPS accepts hemp-derived CBD under Publication 52 section 453.37: the product must test at 0.3 percent THC or less, and the mailer must retain lab test results, licenses or compliance records for at least 3 years after the mailing date. Hemp and CBD cannot go to international, APO, FPO or DPO addresses. Some state destinations restrict the product regardless of federal status.
