✓Well SupportedConsuming a few ounces of liver daily does not raise concerns about copper toxicity due to the presence of zinc.✓Well SupportedConsuming half an ounce of liver daily during pregnancy is safe and provides essential nutrients for fetal development.✓Well SupportedAn ounce of liver is unlikely to cause copper overload due to the body's regulation of copper and zinc.✓Well SupportedKidney, due to its diamine oxidase content, may be beneficial for managing histamine-related issues.✓Well Supported

Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

Five ounces of cow's liver per day, consumed for years, would contain approximately 25,000 IU of vitamin A, the threshold for potential toxicity.

✓Well SupportedOverconsumption of zinc without adequate copper can cause copper deficiency, leading to testosterone deficiency.

◐Partially SupportedThe liver functions as an enzymatic factory that biotransforms compounds for excretion, rather than storing toxins.

◐Partially SupportedHemoglobin levels below 10.0 g/dL preclude home births in standard obstetric practice.

◐Partially SupportedCopper deficiency anemia (CDA) may be a more prevalent form of anemia globally than iron deficiency anemia, despite widespread iron fortification.

◐Partially SupportedCopper deficiency can manifest with neurological symptoms, including balance and coordination issues.

◐Partially SupportedVitamin A deficiency is significantly more common than vitamin A toxicity.

◐Partially SupportedHemodilution during pregnancy naturally lowers hemoglobin and hematocrit levels, and a drop in these levels indicates proper physiological adaptation.

◐Partially SupportedKidneys store more heavy metals than the liver.

◐Partially SupportedTaking 40-50mg of zinc daily without copper can deplete copper levels.

◐Partially SupportedPolar bear liver contains approximately 100 times more vitamin A than cow liver.

◐Partially SupportedA drop in hemoglobin and hematocrit during pregnancy indicates successful hemodilution and provides blood reserves for postpartum.

◐Partially SupportedClients are advised to intuitively determine their own dosing for liver consumption by assessing how they feel.

◐Partially SupportedAn animal-based diet, potentially including desiccated liver capsules, may lead to a more optimal pregnancy experience with less hemodilution compared to diets high in refined carbohydrates.

◐Partially SupportedIncluding organ meats in the diet could address both zinc and copper needs.

◐Partially SupportedCopper is essential for human life and is a cofactor for enzymes like diamine oxidase and superoxide dismutase.

◐Partially SupportedAnemia in pregnancy can be caused by nutritional deficiencies and physiological hemodilution.
