Why did my CBD tincture turn pink?
Did you know your tinctures can turn into a pink CBD tincture when the Polyphenol Oxidase enzyme in MCT Oil is exposed to light and oxygen? Ironically, the pink color is proof your MCT Oil is of the highest quality, so it is 100% safe to use! To prevent your CBD Oil from turning pink, simply leave it in your refrigerator after taking your dose.
Reacting to Light and Oxygen
CBD has low bioavailability, making it hard for the body to absorb. To enhance absorption, CBD oils are often blended with MCT oil, also known as coconut oil, to boost the body’s ability to assimilate CBD into the bloodstream.
The pink hue in CBD tincture is a natural outcome of polyphenol oxidase, an enzyme in MCT oil, reacting to light and oxygen exposure. This reaction does not affect the quality of your CBD oil, but it indicates the use of high-quality MCT oil in your CBD product.
Think of an apple that turns brown when cut and left out, this is due to the same enzyme. Polyphenol oxidase oxidizes polyphenols in the product when it reacts with oxygen.
Thus, when your CBD oil appears pink, it simply means that the product has been exposed to more light and oxygen and the polyphenol oxidase enzymes are reacting with the MCT oil in your CBD oil.
This also confirms the presence of coconut oil in your CBD oil, as coconut oil mainly consists of saturated medium-chain triglycerides (MCT) but also includes polyphenolic antioxidants that react with the mentioned enzyme.
