Gentle and Highly Absorbable Iron Formula
Iron is an important component of hemoglobin, myoglobin, and ferritin. These proteins are involved in the transport, storage and release of oxygen to the tissues.
Iron deficiency anemia is a very serious problem because it reduces available oxygen to the tissues and leads to hypoxic reactions that cause significant cellular stress and cellular death.
This product uses an iron bis-glycinate form which has been shown to be very gentle on the body, with less gastrointestinal side effects than other forms of iron. In addition, research has demonstrated a higher absorbability and faster rise of iron measures such as serum ferritin with the use of the bis-glycinate form of iron that we have in Iron Power.
Why Iron Power:
Iron bis-glycinate, which is the form used in Iron Power is a well-studied, 100% fully-reacted, patented form of iron exclusively from Albion® Laboratories. The amino acid glycine is actually one of the two starting materials the body uses to synthesize hemoglobin.
Therefore, Iron Power™ contributes two key factors. This form of iron has higher bioavailability, lower toxicity, less food reactivity, less food interactions and has a longer shelf life than any other common form of iron.
Ferrous iron is reacted with glycine to form bis-glycinate chelate, a non-electrically charged compound that is totally nutritionally functional. The absence of electrical charge, uncommon for an iron supplement, makes it less likely that Iron Power™ can interfere with absorption of other minerals such as calcium, vitamin E or vitamin C.
Iron solubility from iron bis-glycine chelate is not affected by pH changes from 2-6. This means it travels unchanged through the stomach, into the intestine, where it is absorbed and released for transport throughout the body.
Patient compliance with iron bis-glycinate appears to be better than that seen with inorganic forms of iron supplements for two reasons. First, the taste: In a study with 145 pregnant women (that concluded daily supplementation with iron bis-glycinate chelate was significantly more effective even at a lower dose than ferrous sulfate) the percentage of taste complaints among the women given ferrous sulfate was 29.8%, while 0% of the women on the bis-glycinate chelate complained about taste. Second, iron bis-glycinate is less likely to have any of the gastrointestinal side-effects associated with standard iron supplementation.*
A published absorption study showed there was a significant correlation between iron absorption of iron bis-glycinate chelate to serum ferritin (r = -0.60, p < 0.03) (The higher the ferritin the lower the absorption and vice versa.) The amount of iron stored in the body regulates iron bis-glycinate chelate absorption.
This translates into less chance of toxicity. Another benefit of the bis-glycinate chelate form of iron over other iron supplements is that it doesn’t act as a pro-oxidant.
How I Use This:
I only use this product with individuals that have iron-deficiency or iron deficient anemia as seen on lab work. The findings would indicate very low serum ferritin (under 25), low iron serum (under 80) and possibly low hemoglobin, red blood cells and hematocrit.
Mild Iron Deficiency:
For milder cases I will use 1 cap – 1-2 times daily with food and possibly with 500 mg of vitamin C supplementation which helps improve absorption.
Moderate Iron Deficiency:
For moderate cases I will use 1 cap 3 times daily with food and with 500 mg of vitamin C supplementation which helps improve absorption.
Iron Deficient Anemia:
For advanced cases, I will use 2 caps – 3 times daily with food and with 500 mg of vitamin C supplementation which helps improve absorption.
*I then retest blood iron levels at 90 day intervals to make sure we are improving the levels and exceeding the amount of iron they need.
