My order was on backorder and that was inconvenient because I had to wait( I ordered 2 bottles) but the customer service addressed my complaint and gave me prompt response as well as solutions. The oil does not change the taste of my coffee or smoothies. The first day I took it, it was at night and the first thing in the morning was an urge to use the restroom( not usual for me), but since then, I have not experienced it again. It is still early for me to say more about this product.
