Does MCT Oil Go Bad?

Generally, oil is resistant to mold and microbial growth. This is most especially true with MCT oil, as it contains medium-chain triglycerides that can reduce the risk of bacterial and yeast growth.

Despite this, MCT oil can still go bad, and it can go bad in two ways.

First, it can go bad to the point of rancidity when stored longer than expected shelf life. On the other hand, it can go off to the point of spoilage when it’s not stored correctly.

This is all because of oxidation, which occurs when the oil is exposed to light, air, and heat.

Considering all these, you might wonder: what is the MCT oil’s shelf life? How long does Iy last?

We’d have to start with the printed date on the label to answer this.

  • Unopened Bottle of MCT oil: Best by date / Use by date + 2 years
  • Opened Bottle of MCT oil: Best by date / Use by date +1 year

How To Tell If MCT Oil Is Bad?

Strong FlavorMCT oil is tasteless. A strong flavor or weird taste indicates the oil has gone bad and should be disposed of.
Off SmellMCT oil is odorless. A strong, unpleasant, sour or pungent scent indicates spoilage.

TurbidityMCT oil is clear. If it becomes cloudy or turbid, it’s best to discard the oil immediately.
Thicker ConsistencyMCT oil is thin and lightweight. A thicker, denser consistency indicates spoilage and the oil should be discarded.

3. Discoloration

It typically has a pale yellow color. If your oil looks discolored, it may be a sign of spoilage. However, it’s not a reliable sign of rancid oils, as discolored oil can still be safe for consumption at times.

4. Turbidity
