I'm glad you asked this - I'm watching this too. We raise most of our food - meat, fruits and vegetables. So we eat a lot of pasture raised meat. And I've been slowly getting my family to eat more liver, gizzards, heart, etc. But I haven't taken the cod liver oil step yet b/c I'm still unsure of the vitamin A question.
I do feel better drinking raw milk. Yes, it will still cause mucus buildup if I have a cold. But when it comes to comparing it to regular organic milk, I like how I feel much more.
