Stomach acid levels heavily interact synergistically with iron and manganese, whereby the absorption |
of both minerals is enhanced by higher HCl acid levels, and likewise, an increase in iron or manganese |
will generally - but not always - result in raised stomach acid levels. Since calcium and magnesium have the exact opposite effect on stomach acid levels, their interaction with iron and manganese have |
a major impact on medical conditions that are associated with raised or lowered stomach acid levels |
(see also Acu-Cell "Calcium & Magnesium"). |
|
Excessive manganese and/or iron levels may have set the stage for tumor development perhaps as |
much as 10 or 20 years before a benign or malignant growth formed - subsequent to the exposure to, |
or intake of substances that have adversely affected liver chemistry, such as: |
|
• alcohol, |
• marijuana / cannabis, |
• antifungal medications, |
• acetaminophen (Tylenol), |
• viral infections (e.g. hepatitis), |
• proton pump inhibitors (Nexium), |
• cholesterol-lowering (statin) drugs, |
• food-related mold / mycotoxins (aflatoxin), |
• hormones (e.g. estrogen, androgen, anabolic steroids), |
• heavy metal / toxic exposure (PVC, arsenic, pesticides), |
• dry cleaning chemicals (tetrachloroethylene / perchloroethylene), |
• genetic disposition (alpha-1 antitrypsin deficiency, hemochromatosis), |
• herbal / nutritional supplements (Lakota, kava kava, devil's claw, comfrey, chaparral). |
|
Many other factors or medications (certain antibiotics, anesthetics, tricyclic antidepressants, antiviral, |
antihypertensive, anti-seizure... drugs) can result in higher manganese (and some in excessive iron) |
storage, regardless of actual manganese or iron consumption. However, by the time a tumor develops, many patients don't exhibit liver storage of these elements any longer. In fact, levels may have dropped significantly below normal (which frequently corresponds to perimenopausal or postmenopausal age |
ranges), along with reduced stomach acid levels. High and low manganese levels also tend to coincide with estrogen receptor-positive and estrogen receptor-negative cancers. |
|
From many years of following patients with a similar history, it appears that if stomach acid levels are normalized in time (along with liver functions), these same patients remain largely tumor / cancer-free. |
That approach is also helpful after cancer has developed, where following successful therapy, cancer |
is more likely to stay in remission. (see also Acu-Cell Disorders "Cancer"). |

The primary function of Iron in the body is the formation of hemoglobin, the essential oxygen-carrying |
component of the red blood cell (RBC). In combination with protein, iron is carried in the blood to the |
bone marrow, where with the help of copper, it forms hemoglobin. Red blood cells pick up oxygen from |
the lungs and distribute it to the rest of the tissues, all of which need oxygen to survive. Iron absorbed into the blood is usually bound to the protein transferrin and goes mainly to the bone marrow, where it |
can be used to make red blood cells. |
Myoglobin is a red, iron-containing protein, which stores oxygen for muscle contraction. There is about |
3 to 5 gm of iron in the body, of which hemoglobin represents 65%, while about 30% occurs as ferritin, |
which is the iron storage complex found in the liver, spleen and bone marrow. Neutrophils (white blood |
cells) depend on iron to help generate superoxide to function as a bacteria-destroying agent, whereby inadequate iron levels reduces the effectiveness of the immune system. With severe iron deficiency, |
hemoglobin levels decline and the packed volume of red blood cells, the hematocrit, declines. |
|
Heme Iron from meat is about 10 times more absorbable than iron from all plant / vegetable sources. |
Many vegans have trouble obtaining sufficient iron from the diet alone since phytates present in whole |
grains and oxalates found in certain vegetables may bind to some of the iron and reduce absorption. |
Iron deficiency is more common during infancy, childhood, adolescence, pregnancy, menstruation, chronic infections, low stomach acid (sometimes from low salt intake), chronic diarrhea, bleeding, or impaired absorption (celiac disease). The elderly may become iron deficient due to poorer absorption |
and inadequate dietary intake of iron. Vitamin C also helps iron absorption. |
|
Iron Toxicity (excessive organ storage of iron) and/or high blood levels of iron are associated with |
increased risk of free radical damage and cancer. Ferritin levels are a good indication of iron storage levels. While a normal value is 15-200mcg, levels below 15mcg suggests very depleted iron reserves, and high ferritin (over 200mcg) can be a risk factor for cardiovascular disease. Free radicals formed |
as a result of high iron can attack low-density lipoproteins (LDL) and subsequently lead to fatty plaque |
buildup, damage to the walls of arteries, as well as heart muscle tissue. |
|
Iron supplements frequently cause constipation or stomach complaints, which may result from the use |
of ferrous sulfate, or similar hard-to-digest forms of iron. Other types of iron such as ferrous gluconate, |
ferrous fumarate, or ideally chelated iron supplements are generally better tolerated, and there are also |
water-soluble iron products that are probably the easiest on the system and cause less of these effects. |
|
Manganese is a much neglected, but extremely important mineral when trying to stabilize blood sugar, particularly with hypoglycemic individuals, and for lowering total cholesterol (cholesterol-lowering drugs actually raise manganese). It has strong estrogenic properties, and as a result is the most important element when nutritionally treating menopausal symptoms, osteoporosis, and postpartum depression, |
for which manganese, along with Vitamin B1, is most effective. |
Just like iron, manganese can be helpful with some types of asthma, where lung capacity measurably increases proportional to manganese intake. Extra supplementation of manganese may be helpful in |
some cases of carpal tunnel syndrome, deafness, epilepsy, infertility, and lack of libido in both sexes. |
In addition, individuals who regularly dislocate joints (particularly knee joints), frequently present with |
insufficient cellular manganese levels, so normalizing manganese in those cases will permanently resolve that problem. |
|
Manganese is important to many enzyme systems such as protein metabolism, bone formation, and |
the synthesis of L-dopamine and cholesterol, as well as carbohydrate metabolism, where it is required |
for the synthesis of glucose from non-carbohydrate substances (gluconeogenesis). As a cofactor in |
glycolysis, manganese aids glucose metabolism. |
It is also needed for normal brain and muscle function, blood clotting, and DNA and RNA synthesis, |
and it activates the enzyme responsible for the formation of urea. Manganese may help with some |
symptoms of Parkinson's disease such as muscle rigidity and twitching, although an excessive level |
of manganese can in itself produce Parkinsonian syndrome from a loss of dopamine in the brain cells. |
L-dopa, which converts to dopamine in the brain, is used in the treatment of manganese toxicity to |
reduce the symptoms. High levels of manganese can produce violence and other mental changes, |
including a psychiatric disorder resembling schizophrenia. |
|
When people supplement certain herbs to "cleanse" their liver, they will always affect manganese and |
iron status. For instance, by taking Devil's Claw on an ongoing basis, they will eventually raise iron and manganese levels. On the other hand, taking Milk Thistle will in time decrease iron and manganese |
stores, which can be an advantage with hemochromatosis (excess iron storage disease), where regular |
consumption of milk thistle, RNA / DNA, magnesium and Vitamin B2 - whichever ones are individually indicated - will keep iron levels closer to normal, and frequently eliminate the need for phlebotomies. ¤ |

General recommendations for nutritional supplementation: To avoid stomach problems and promote |
better tolerance, supplements should always be taken earlier, or in the middle of a larger meal. When |
taken on an empty stomach or after a meal, there is a greater risk of some tablets causing irritation, or eventually erosion of the esophageal sphincter, resulting in Gastroesophageal Reflux Disease (GERD). |
It is also advisable not to lie down immediately after taking any pills. |
When taking a very large daily amount of a single nutrient, it is better to split it up into smaller doses to |
not interfere with the absorption of other nutrients in food, or nutrients supplemented at lower amounts. |
