The safest way to dispose of vitamins is to mix them with an unappealing substance like used coffee grounds, dirt, or cat litter, seal the mixture in a plastic bag or container, and throw it in your household trash. This method, recommended by the FDA, prevents children, pets, or anyone else from accidentally ingesting discarded supplements. Don’t crush tablets or capsules before mixing, and don’t flush vitamins down the toilet.
Step-by-Step Home Disposal
The process takes about two minutes and works for all forms of vitamins: tablets, capsules, gummies, liquids, and softgels. Here’s what to do:
- Gather your vitamins. Remove pills from their original bottles. For liquids, keep them in the bottle for now.
- Add a deterrent substance. Place the vitamins (or pour the liquid) into a resealable plastic bag or container, then mix in used coffee grounds, cat litter, or dirt. The goal is to make the contents look and smell unpleasant so no one would want to touch or eat them.
- Seal and toss. Close the bag or container tightly and place it in your regular household trash. Not in your recycling bin.
One important detail: don’t crush tablets or capsules before mixing them in. Crushing can cause the contents to release more quickly if someone or something does come into contact with them.
Drug Take-Back Programs
If you’d rather not deal with the mixing method, many pharmacies and police departments accept unused medications and supplements through take-back programs. The DEA organizes National Prescription Drug Take-Back events twice a year (typically in April and October), and many pharmacies maintain permanent drop-off bins year-round. These programs handle the disposal for you and are especially convenient if you’re clearing out a large medicine cabinet.
Check with your local pharmacy or search the DEA’s collection site locator to find a drop-off point near you. Most accept dietary supplements alongside prescription and over-the-counter medications.
Why Not Flush Them or Pour Them Down the Drain
Flushing vitamins introduces their ingredients into the water supply. Wastewater treatment plants aren’t designed to filter out all pharmaceutical and supplement compounds, so traces can end up in rivers, lakes, and drinking water. The FDA only recommends flushing for a small list of highly dangerous medications (mostly opioids) where the risk of accidental ingestion outweighs the environmental concern. Vitamins are not on that list.
Pouring liquid supplements down the sink creates the same problem. Even water-soluble vitamins like B and C can contribute to excess nutrient loads in waterways.
Do Expired Vitamins Need Special Handling?
No. Expired vitamins lose potency over time, but they don’t become toxic. Military-funded research found that over 90% of more than 100 medications and supplements tested remained suitable for use even 15 years past their expiration dates. The main issue with expired vitamins is that they may not deliver the dose listed on the label.
That said, throw away any vitamins that show signs of mold, have developed a strange odor, or have changed color or texture. These changes suggest contamination rather than simple aging. Dispose of them using the same coffee-grounds-and-bag method described above.
What to Do With the Bottles
Most vitamin bottles are made from HDPE (recycling code 2), which is widely accepted by municipal recycling programs. Before recycling, remove any remaining pills, peel off the label if your program requires it, and remove the cotton filler or desiccant packet inside. Rinse the bottle if it held a liquid supplement.
Caps are often a different plastic, typically polypropylene (code 5). Some recycling programs accept them, others don’t. Check your local guidelines. If your program doesn’t take caps, toss them in the trash separately. The bottles themselves are almost always recyclable since HDPE is one of the most commonly accepted plastics alongside PET (code 1).
Glass supplement bottles can go in your glass recycling. Blister packs, the foil-and-plastic sheets that hold individual pills, are generally not recyclable through curbside programs because the mixed materials are difficult to separate.
