Personal trainer Laura Ghiacy, who is based in Los Angeles, attempted to make Kourtney Kardashian's $18 Poosh Potion Detox Smoothie.

The smoothie was made available at Erewhon stores on November 15.

Ghiacy and the video's filmer both tried the expensive drink and came to the conclusion that it wasn't worth the $18 price tag.

The personal trainer then attempted to make the smoothie at home. She explains that Erewhon doesn't note how much of an ingredient they use.

Ghiacy's detox smoothie is made using coconut milk, lactose-free milk, homemade charcoal, salt, maple syrup, cacao powder, and other ingredients.

The personal trainer is shocked when she tastes her creation and finds out it tastes better than the $18 version.
