The connection between vitamin A and hypothyroidism should come as no surprise. Vitamin A is needed for healthy hormone production; when you have a lack of hormonal balance (by having estrogen dominance, for example), it will actually block thyroid production! According to Dr. Ray Peat, “Estrogen blocks the release of hormone from the thyroid gland, and progesterone facilitates the release. Estrogen excess or progesterone deficiency tends to cause enlargement of the thyroid gland, in association with a hypothyroid state.”

WHY ARE AMERICANS DEFICIENT IN VITAMIN A?

I see two main reasons for vitamin A deficiencies:1) Low and fat-free diets: That egg white omelet, skim milk, and butter-less toast are at the center of this problem. You see, the fat soluble vitamins (like vitamin A, but also vitamins D, E, & K) are found in the FAT, and when you eat low-fat, you lose these hormone, thyroid and metabolism stimulating nutrients!


2) Saturated fat avoiding diets. When Americans were led astray by the mainstream media to DITCH saturated fat for polyunsaturated fat (ie. butter for vegetable oils), our nutrition really suffered. Foods containing saturated fat (like egg yolks, butter, cream, whole milk) are naturally high in vitamin A, where as vegetable oils and margarine are not. Catch up on the how polyunsaturated fats contribute to disease and speed the aging process here.

SOURCES OF REAL VITAMIN A (RETINOL- ANIMAL SOURCE)

It’s important to note the difference between plant (beta-carotene) and animal sources (retinol) of vitamin A . Plants contain beta-carotene that is actually the precursor to Vitamin A, meaning it requires conversion by the body (and those who are vitamin A deficient are usually poor converters). The easiest way to ensure that you are getting sufficient amounts of Vitamin A is to include foods like butter, eggs, whole milk, cream, and liver in your daily diet! If you hate the taste of liver, I highly recommend a real food supplement like this!
P.S. Vitamin A is a fat soluble vitamin, so excess vitamin A is stored in the body and not excreted. This means taking high dosages can put you at risk of vitamin A toxicity. That’s why I only recommend food sources of vitamin A, unless you’re working with a healthcare practitioner.
