If you're on a keto diet and are willing to spend the money ( It's about $22/mo with their subscription plan) I highly recommend the mct oil from onnit. It's just a pure version of coconut oil, but I also love it just for the convenience - it comes in one of those dripper bottles that you can pour the oil out with and it's amazing for when youre on the go. I also put some heavy cream or almond milk in my coffee alongside the oil.
