Spinach contains iron. You absorb 2% of it. Beef contains iron. You absorb 25% of it. Almonds contain calcium. Phytates lock most of it away. Sardines contain calcium. Fully bioavailable. Lentils contain zinc. Bound up. Mostly unusable. Oysters contain zinc. Highest bioavailable source on earth. Carrots contain beta-carotene. Your body converts it to retinol at roughly 10% efficiency. Less if you're a man. Less again if your thyroid is sluggish. Eggs contain retinol. Already done. The plant version is presented as equivalent. It is not equivalent. The body knows the difference.

The marketing department was hoping you wouldn't.
