Ever stumbled upon an old bottle of MCT oil lurking at the back of your pantry and wondered if it's still good to use? You're not alone!
MCT oil is a beloved staple in many health-conscious kitchens, but like all oils, it doesn't last indefinitely. In this post, we'll dive into whether MCT oil expires, how to recognize if yours has gone bad, and the best practices to store it for maximum freshness.
Key takeaways
- MCT oil typically lasts about two years when stored properly in a cool, dry, and dark place
- Watch for signs of spoilage like a rancid smell, unpleasant taste, or changes in color and texture
- Oxidation accelerates degradation once the bottle is opened, so always seal it tightly after use
What is the shelf life of MCT oil?
So, does MCT oil expire? The short answer is yes.
Most manufacturers say that MCT oil has a shelf life of roughly two years, especially when unopened. This "best by" or "use by" date is a helpful guideline, but your oil could last even longer with proper storage.

How to store MCT oil for maximum freshness
Looking for the best spot to store your MCT oil? Here are some storage tips to keep it fresh:
- Keep it cool: Store your MCT oil in a cool, dry place away from direct sunlight. A pantry or cupboard works perfectly.
- Avoid heat sources: Don't keep it near the stove or oven, as heat can accelerate spoilage.
- Seal it tight: After each use, make sure the lid is screwed on securely to minimize exposure to air.
- Refrigerate if you want: While not necessary, refrigeration may help extend the oil's freshness beyond two years.
Do’s
Do store it properly in a cool, dark place.
Do check the expiration date and note when you opened it.
Do use clean utensils when handling the oil to prevent contamination.
Do start with small amounts if you're new to MCT oil to assess tolerance.
Don’ts
Don't leave the bottle open or poorly sealed.
Don't store it near heat sources like ovens or sunny windowsills.
Don't consume the oil if it shows signs of spoilage.
Don't use it for high-heat cooking, as it has a low smoke point.
Does refrigeration affect shelf life?
Unlike coconut oil, MCT oil doesn't solidify at cooler temperatures unless it drops below freezing (0°C or 32°F). If your refrigerated MCT oil turns solid, it might not be pure MCT oil. This could be a sign that it's mixed with other fats.

Identifying spoiled MCT oil
No one wants to consume spoiled oil! Here are the telltale signs that your MCT oil may have gone bad:
- Rancid smell: Fresh MCT oil should be odorless or have a very mild scent. A strong, unpleasant odor is a major red flag.
- Unpleasant taste: If it tastes off or bitter, it's time to toss it.
- Color changes: Pure MCT oil is usually clear. Yellowing or dark spots could indicate contamination.
- Texture changes: If the oil becomes lumpy or excessively thick, it might not be safe to consume.

Remember, when in doubt, it's better to be safe and replace old MCT oil. Proper storage extends its shelf life, so make sure to keep it cool, dry, and tightly sealed.
