Iron Supplement in WikiPedia

Iron can be supplemented by the oral route using various pharmacological forms, such as iron(II) sulfate (this is the most common and cheapest salt, e.g. Feratab, Fer-Iron, Slow-FE,…) and in complex with gluconate, dextran, carbonyl iron, and other salts. Sometimes ascorbic acid is added for better absorption.

Heme iron polypeptide (HIP) (e.g. Proferrin ES and Proferrin Forte) can be used when regular iron supplements such as ferrous sulfate or ferrous fumarate are not tolerated or absorbed. A clinical study demonstrated that HIP increased serum iron levels 23 times greater than ferrous fumarate on a milligram-per-milligram basis. {Click here for details or studies and purchase also patented}

Another alternative is ferrous glycine sulfate or ferroglycine sulfate, has less gastrointestinal side-effects than standard preparations such as iron fumarate, It is unusual among oral preparations of iron supplements in that the iron in this preparation has very high oral bio-availability esp in the liquid version (e.g. Hemfer by Alkem).This option should be evaluated before resorting to parenteral therapy. It is especially useful in iron deficiency anemia associated with autoimmune gastritis and Helicobacter pylori gastritis, where it generally has satisfactory effect.

Since iron stores in the body are generally depleted, and there is a limit to what the body can process (about 2–6 mg/kg of body mass per day; i.e. for a 100 kg/220 lb man this is equal to a maximum dose of 200–600 mg/per day) without iron poisoning, this is a chronic therapy which may take 3–6 months.

Due to the frequent intolerance of oral iron and the slow improvement, parenteral iron is recommended in many indications

  • Adults will usually require a dose of 60-200 mg of elemental iron daily, depending on the severity of the anemia.2
    Since the amount of iron absorbed decreases as doses get larger, most people should take their daily iron supplement in two or three equally spaced doses.
  • Iron supplements are available in regular tablets and capsules, liquid, drops, and coated or extended-release tablets and capsules.

The antibacterial protein hepcidin regulates the absorption, tissue distribution, and extracellular concentration of iron by suppressing ferroportin-mediated export of cellular iron. In CKD, elevated hepcidin and vitamin D deficiency are associated with anemia. Therefore, we explored a possible role for vitamin D in iron homeostasis. Treatment of cultured hepatocytes or monocytes with prohormone 25-hydroxyvitamin D or active 1,25-dihydroxyvitamin D decreased expression of hepcidin mRNA by 0.5-fold, contrasting the stimulatory effect of 25-hydroxyvitamin D or 1,25-dihydroxyvitamin D on related antibacterial proteins such as cathelicidin. Promoter-reporter and chromatin immunoprecipitation analyses indicated that direct transcriptional suppression of hepcidin gene (HAMP) expression mediated by 1,25-dihydroxyvitamin D binding to the vitamin D receptor caused the decrease in hepcidin mRNA levels. Suppression of HAMP expression was associated with a concomitant increase in expression of the cellular target for hepcidin, ferroportin protein, and decreased expression of the intracellular iron marker ferritin. In a pilot study with healthy volunteers, supplementation with a single oral dose of vitamin D (100,000 IU vitamin D2) increased serum levels of 25D-hydroxyvitamin D from 27±2 ng/ml before supplementation to 44±3 ng/ml after supplementation (P<0.001). This response was associated with a 34% decrease in circulating levels of hepcidin within 24 hours of vitamin D supplementation (P<0.05).
These data show that vitamin D is a potent regulator of the hepcidin-ferroportin axis in humans and highlight a potential new strategy for the management of anemia in patients with low vitamin D and/or CKD.

Hepcidin is a peptide hormone produced by the liver.
It was discovered in 2000, and appears to be the master regulator of iron homeostasis in humans and other mammals

  • Serum Ferritin and GGT — Two Potent Health Indicators You Need to Know Sept 2017
    "Iron Overload Is More Common Than Iron Deficiency"
    "In recent years, scientists have discovered GGT is highly interactive with iron, and when both your serum ferritin and GGT are high, you are at significantly increased risk of chronic health problems, because then you have a combination of free iron, which is highly toxic, and iron storage to keep that toxicity going"

    Kerri Knox April 2017 "VITAMIN D AND IRON ARE COFACTORS OF EACH OTHER, Case in point is our discussion here. Interestingly, the relationship between Vitamin D and Iron possibly runs both ways, as the research suggests that each are cofactors for each other. If you don’t have enough vitamin D, you can’t absorb iron properly; if you don’t have enough iron, you can’t have adequate vitamin D levels."
