# Anemia

Category: Conditions

Anemic means lacking blood, in the sense of not having enough red blood cells or hemoglobin. It is possible to have too much iron in the blood while being anemic. Anemia in itself doesn't imply that there is nutritional need for iron.

## Synthesis

**Anemia** is defined as a deficiency of red blood cells or hemoglobin, but Ray Peat argued it is a profound medical error to equate this condition with a nutritional need for iron. [Source 1, 5] He emphasized that anemia is fundamentally *low blood*, and that it is entirely possible to have **iron overload** in the tissues while presenting with an anemic blood profile. [Source 1, 2] Peat pointed to historical evidence showing that so-called anemic children with lower hemoglobin levels were often healthier than those with "normal" levels, and that toxic substances like arsenic were once used effectively to stimulate red blood cell production, proving that a hematopoietic response does not indicate a deficiency of the stimulating toxin. [Source 2, 5, 7]

The primary driver of this apparent paradox is **estrogen**, which Peat identified as a central agent in the pathophysiology of anemia. Estrogen causes the body to retain iron but simultaneously blocks its utilization in the bone marrow, lowering hemoglobin and hematocrit while promoting iron accumulation in tissues. [Source 2, 4] This mechanism explains why women, who have higher estrogen levels, naturally have lower hemoglobin than men and absorb dietary iron much more efficiently, a process that intensifies during pregnancy. [Source 4, 7] Peat also identified **hypothyroidism** as perhaps the most common cause of anemia, citing Broda Barnes’s work and an experiment where a rat’s tail, normally too cold to produce blood cells, began generating them rapidly when surgically kept at core body temperature. [Source 4] He maintained that androgens directly oppose this process by stabilizing the bone marrow and increasing its temperature and productivity. [Source 2]

Georgi Dinkov has extended this framework by clarifying the clinical confusion surrounding *anemia of chronic disease*. He explained that this condition is a misnomer for a state of **iron overload**, where serum iron is low but intracellular iron, indicated by high ferritin and transferrin saturation, is dangerously elevated. [Source 8] In this protective adaptation, the body sequesters iron from the blood into tissues, making iron supplementation extremely dangerous and making iron chelation or bloodletting the appropriate intervention. [Source 8] Dinkov also noted that standard blood tests are often insufficient, and that a full iron panel including ferritin, saturation index, and TIBC is necessary to distinguish true deficiency from this functional, inflammatory block. [Source 3, 8]

Peat considered true **iron deficiency anemia** to be a real but rare condition, primarily occurring in cases of chronic bleeding, and insisted it should be the last-suspected cause rather than the first. [Source 5, 7] He warned that the routine prescription of iron supplements is biologically unreasonable and dangerous, as excess iron destroys vitamin E, oxidizes red blood cell membranes, and can cause *hemolytic anemia*, where cells break down too fast. [Source 7] For those with a genuine need to increase iron, Danny Roddy has summarized that thyroid function is crucial for producing the liver protein that assimilates iron, and that dietary sources like liver and oysters, along with adequate **copper** for cytochrome oxidase function, are safer than supplements. [Source 4, 6] Peat ultimately recommended therapeutic phlebotomy as a beneficial practice for many people to reduce the accumulated iron that acts as a signal accelerating the aging process. [Source 9]

## People also ask

### How does estrogen cause anemia while increasing iron stores?

Peat argued that estrogen blocks iron utilization in the bone marrow, lowering hemoglobin, while simultaneously causing the body to retain iron in tissues, creating a state of iron overload with an anemic blood profile.

### Why is hypothyroidism considered a common cause of anemia?

The corpus describes an experiment where a cold rat tail could not produce blood cells until surgically warmed, leading Peat to conclude that low thyroid function reduces bone marrow temperature and productivity, making hypothyroidism a primary driver of anemia.

### What is the danger of taking iron for anemia of chronic disease?

Dinkov explained that this condition is actually a state of dangerous iron overload where the body sequesters iron into tissues, so iron supplementation is extremely dangerous and the appropriate intervention is iron chelation or bloodletting.

> **Ray Peat:** No, anemia is low blood, low hematopoietin, low hemoglobin. About 50 years ago, someone was studying the health of California migrant workers and found that the kids running around somewhat hungry and dirty were healthier than the local middle-class Anglo kids. One of the features of the very poor immigrant kids was a hemoglobin of 10 or 10.5. It isn't just malaria in Africa that flares up and kills people when they give them an iron supplement; right in the U.S., they can see that so-called anemic kids are healthier than the ones with the so-called normal levels.

> **Danny Roddy:** So by iron overload, you mean the accumulation of unusable iron in the forms of lipofuscin and other iron complexes?
>
> **Ray Peat:** Yeah. Estrogen is one of the things that causes you to retain iron but protectively lowers your hemoglobin and hematocrit. For 100 years, doctors have looked at women with very low hematocrit or hemoglobin and prescribed iron pills, keeping prescribing it even if their hemoglobin got lower, not understanding that the same thing that makes them overload on iron is blocking their bone marrow formation of red blood cells.

> **Ray Peat:** Yeah, all animals that have estrogen, the female tends to look slightly anemic. Right. Because it does something to slow the production of red blood cells, partly lowering the body temperature is one of the actions of estrogen. slowing down thyroid function so probably the most common cause of apparent anemia as Rhoda Barnes pointed out is hypothyroidism and I think he was the one that mentioned the experiment in which rats whose tail bones normally don't make red blood cells in this experiment they folded the tail back and made a hole in the skin of the abdomen and stitched the tail so it was kept in at core body temperature. And it quickly began producing red blood cells, just raising the temperature. And so the first, safest way to treat anemia might be to wear long wool socks. to warm the extremities.
>
> **Josh Rubin:** Right. Now, what is copper's role in regards to iron? I mean, I know copper is important for iron uptake and utilization.

> **Question:** What should I do if my doctor tells me I'm anemic? Is there any situation in which a person needs to take iron supplements?
>
> **Ray Peat:** Iron deficiency anemia does exist, in laboratory situations and in some cases of chronic bleeding, but I believe it should be the lastsuspected cause of anemia, instead of the first. It should be considered as a possible cause of anemia only when very specific blood tests show an abnormally low degree of iron saturation of certain proteins. Usually, physicians consider the amount of hemoglobin or of red cells in the blood as the primary indicator of a need for iron, but that just isn't biologically reasonable. If a large amount of blood is lost in surgery, a temporary anemia might be produced, but even then it would be best to know whether the iron stores are really depleted before deciding whether an iron supplement would be reasonable. Liver (or even a water extract of wheat germ) can supply as much iron as would be given as a pill, and is safer.

>
> **Danny Roddy:** did you uh how to decrease uh increase or decrease increase in increase like i
>
> **Caller:** think i think i was just like over years like drinking too much and too little like meat and stuff so how how go about
>
> **Danny Roddy:** Got it. You know what, guys? I should probably say, we probably do like one or two questions. Some of the calls were like 10 minutes each. And so I'll never get through everybody if they're that long. And so if I do answer the question and then you just go back to the back of the line and then I'll try to answer your question again. But to increase iron, I think thyroid is involved. Like Broda Barnes has a whole chapter about anemia in his thyroid book. And I think it stimulates a protein from the liver to make, to assimilate iron. It's very important. And obviously, I mean, you probably already know this, but liver and oysters are good sources of iron and you need copper in addition to iron to resolve anemia symptoms. Those are the main things I think of. What am I missing?

### Source 7 — Iron: Cumulative Danger

Ray Peat · Newsletter · Jun 1997

> **Question:** Don't you need iron supplements if you are anemic?
>
> **Ray Peat:** In general, no. Many doctors think of anemia as necessarily indicating an iron deficiency, but that isn't correct. One-hundred years ago, it was customary to prescribe arsenic for anemia, and it worked to stimulate the formation of more red blood cells. The fact that arsenic, or iron, or other toxic material stimulates the formation of red blood cells doesn't indicate a deficiency of the toxin, but simply indicates that the body responds to a variety of harmful factors by speeding its production of blood cells. Even radiation can have this kind of stimulating effect, because growth is a natural reaction to injury. Between 1920 and 1950, it was common to think of nutritional growth factors as being the same as vitamins, but since then it has become common to use known toxins to stimulate the growth of farm animals, and as a result, it has been more difficult to define the essential nutrients. The optimal nutritional intake is now more often considered in terms of resistance to disease, longevity or rate of aging, and even mental ability. An excess of iron, by destroying vitamin E and oxidizing the unsaturated fats in red blood cells, can contribute to hemolytic anemia, in which red cells are so fragile that they break down too fast. In aging, red cells break down faster, increasing the tendency to become anemic, but additional iron tends to be more dangerous for older people. Anemia in women is caused most often by a thyroid deficiency, or by various nutritional deficiencies. Estrogen (even in animals that don't menstruate) causes dilution of the blood, so that it is normal for females to have lower hemoglobin than males.

### Source 8 — The Myths of Supplementation with Giorgi Dinkov

Georgi Dinkov · Interview · Oct 9, 2024 · https://www.youtube.com/watch?v=bHQnx-5PjFM

> **Georgi Dinkov:** So let's say a woman is having her period, right? Maybe she had blood loss over the last couple of days and she appears to have low serum iron. That does not mean that her total iron body stores have been depleted. um and there is this this other condition it's called anemia of chronic disease uh and actually it's a misnomer because it's it's really not anemia but it's actually iron overload so if you look at these people's results if you do some additional iron tests for things such as ferritin transferring and iron saturation index And those are basically indications of what are the levels of iron inside of the cell. People with anemia of chronic disease, just like the people with iron deficiency anemia, they'll have low iron in the blood, but they will have extremely high iron inside of the cell. So giving these people more iron is actually extremely unproductive and, in fact, very, very dangerous. So these people are actually in a state of iron overload, and it's the body's essentially adaptive response increasing some of these iron-carrying proteins, specifically ferritin, to basically sequester iron from the blood and keep it in the tissues because the body thinks that extra iron at this point in time, having iron in the blood is actually detrimental to your health. So your body's trying to protect you. And many people with chronic diseases tend to have this that's why it's so called anemia of chronic disease. But the name is a bit of a misnomer. It's not anemia. It's actually, you're perfectly fine. You have these people produce sufficient hemoglobin, sufficient hematocrit, right? Sufficient amount of red blood cells. And in fact, their iron levels in the cell are very, very high. So for those people, believe it or not, it's actually iron chelation therapy that needs to be done. or other methods to actually get rid of this extra iron that is inside of the cells.

>
> **Ashley:** Oh, very cool. I'm curious your opinion on donating blood to reduce stored iron.
>
> **Ray Peat:** I think it's a good idea for many people.
>
> **Ashley:** yeah i know it can be super stressful so we always make sure that we um support it with meals before and after to make sure that we replenish but yeah i think we have several years of stored iron especially with amenorrhea oh
