Vitamin A / D ratio and timing

Answered on August 19, 2014

I've been reading about concerns regarding the ratio of vitamin A to vitamin D (particularly in the context of cod liver oil, but more generally as well -- it might explain the inconsistent findings about vitamin A and harm to health).

To my knowledge, both vitamins are fat-soluble and stay in your body a long time, to be used as needed. Does that mean that the scheduling and distribution of A and D doses isn't important, as long as you get appropriate amounts of each over a scale of, say, a week? This seems like the most likely pattern if you're getting them from food, especially liver. Or is there an absorption / processing issue that means it's important to consume them at the same time?

Related question: The Weston A Price website makes a huge deal about finding a cod liver oil that has enough vitamin D to balance the A, which ends up meaning you have to buy obscenely expensive fermented oils from a very limited set of suppliers. Would it be just as effective to take a high-A oil and use a separate D supplement?

A "Quantum cause" for pseudotumors.. based on "quantum time" and chronic "blue light" toxicity? I don't know what the hell this guy's talking about.

be careful with Vitamin A and D.......they are quite misunderstood by most clinicians and researchers.

Rarely do we need Vitamin A in supplement form.
