Top critical review
It's a supplement, Oil blend - not pure flax seed oil.

NOT for seasoning cast iron. Didn't work well for me. After more research I found a material scientist that suggested vegetable shortening (Crisco) is close to ideal for cast iron seasoning. Flax seed oil is too brittle when hardened. I season with Crisco and cook with peanut oil in a ketchup squirter and I'm happy. This stuff is better used for nutritional value.
