Dr. Ray Peat’s advice on vitamin A.

According to Dr. Ray Peat, vitamin A is very important for your health, it has anti-aging, anti-acne, and anti-estrogenic properties.

Vitamin A is used in the production of the body’s anti-stress and anti-aging hormones. Pregnenolone, progesterone and DHEA.

In order to make the first protective anti-stress and anti-aging hormone pregnenolone, the body needs cholesterol, vitamin A and red light. From pregnenolone, progesterone and DHEA are made, all these hormones are crucial in the body’s resistance to stress and aging. Thus, vitamin A is an important part of our protective hormone system.

In my hypothyroid treatment program, you can learn more about the importance of the body’s protective hormones, and which symptoms indicate that your production of pregnenolone, progesterone and DHEA is too low.

Symptoms of vitamin A difficiency

Symptoms of vitamin A deficiency include skin problems such as dry skin, acne, and dandruff. Other symptoms include problems with night vision and hormonal issues due to the lack of synthesis of the protective hormones.

Food with vitamin A

Several foods contain vitamin A. From highest to lowest content these include: Cod liver, turkey liver, beef, pork and fish liver, chicken liver, ghee, butter, cheddar cheese, eggs, and milk. With a diet high in these foods most people get enough vitamin A.

Supplementing with vitamin A

However, the higher your thyroid function the more vitamin A is needed and the more of the protective hormones are formed. According to Dr. Ray Peat, a normal supplement dose of vitamin A is around 10.000 IU. But a person with a very high thyroid function might need 50.000 IU in order to avoid problems with vitamin A deficiency.

On the other hand, if you have a low thyroid function you need to be careful not overdosing with vitamin A, as it can have anti-thyroid effects.
If your thyroid function is low, using a vitamin A supplement is generally not advisable. You can get an idea of your thyroid function by testing your thyroid using pulse and temperature.

Importantly beta-carotene supplements are not recommended by Dr. Ray Peat. First of all very little of the beta-carotene is converted to vitamin A, and beta-carotene has a similar structure to polyunsaturated fats, which inhibits thyroid function. You can learn more about which foods inhibits thyroid function in my hypothyroid treatment program.

Vitamin A brands

I use a liquid form of vitamin A called Vitasorb A from the brand BioCare. This liquid vitamin A can be used both internally and on the skin.

For optimal general effect, I recommend using this product internally. However, I also use it on the skin for its anti-aging and anti-acne effect. Each night I use about 5 drops Vitasorb A mixed with my night skin care, for a great night serum!

I have collected a list of high-quality Dr. Ray Peat inspired nutritional supplements that are supportive of a healthy thyroid function and good hormonal balance. You can shop many of the supplements with BiochemNordi’s discount.
