When was the last time you checked the expiration date on your magnesium supplements? If you're like most people, that bottle might have been sitting in your cabinet for who knows how long.
But does magnesium actually expire? Let's dive into the facts to find out whether you should toss it or trust it.
Key takeaways
- Magnesium supplements are generally stable and don't degrade significantly over time
- Proper storage in a cool, dry place may help maintain potency
- Expired magnesium isn't unsafe, but it may be less effective
Do magnesium supplements expire?
Technically, minerals like magnesium don't "expire" in the way perishable foods do. Magnesium is an element, which means it doesn't degrade over time.
This stability means that magnesium supplements may remain effective for a long time, especially when stored properly.
However, the other ingredients in your supplement might. While the FDA doesn't require expiration dates on dietary supplements, many reputable companies include them to indicate when the product might start losing potency.
Proper storage
How you store your supplements plays a crucial role in their longevity. Storing them in a cool, dry place away from direct sunlight helps maintain their potency.
Make sure the container is properly sealed after each use to prevent moisture and air from degrading the product.
To get the most out of your magnesium:
- Store them properly: Keep supplements in a cool, dry place.
- Seal tightly: Ensure the lid is closed after each use.
- Avoid transferring: Keep them in their original container to reduce exposure.
- Check regularly: Periodically inspect for any changes in appearance or smell.

Is it safe to take expired magnesium?
You might be wondering, "May I still take magnesium after its expiration date?" The good news is that expired magnesium supplements are likely safe to consume.
However, they may not be as potent, meaning you might not reap the full benefits. If they're significantly past the expiration date or show signs of degradation, it's best to replace them.
Signs your magnesium supplement has gone bad
Even though magnesium itself doesn't expire, the other components in the supplement may deteriorate. Look out for signs like discoloration, unusual odors, or changes in texture.
If your magnesium tablets are crumbling or your capsules are sticky, it's time to err on the side of caution and discard them.
