I believe Chosen brand is legitimate, but yeah, most others are rancid or cut with seed oils.

I personally like Chosen's avocado oil for sure.
Costco's cold-pressed olive oil (extra virgin because no duh) is also a good option, and I don't get any seed oil effects.
The best for me is actually goat milk butter (the Meyenburg European-style goat milk butter is fantastic).
I wish we had a Costco around. We use Terra Delyssa for extra virgin olive oil. It's high quality and tasty - tastes a bit buttery.
I've seen that goat milk butter but haven't tried it. I might have to. We got some goat milk ghee from Mt. Capra, but haven't actually tried it yet.
I love high quality food. 😍
