## Description

EC0100 Ecological Formulas/Cardiovascular Research Ferritin 60C Ec0100 Tags: Ecological Formulasandrsquo; Ferritin Bioavailable Iron Capsules contain a powerful formula that delivers 5 milligrams of ferritinandsbquo; the key protein responsible for iron storage in your body. This supplement also provides ironandsbquo; the essential mineralandsbquo; in its most bioavailable form for easier absorption. The ferritin in this exclusive formula is a natural derivative of bovine spleen. Unlike many other iron supplementsandsbquo; Ferritin Bioavailable Iron doesnandrsquo;t cause negative side effectsandsbquo; such as nausea and GI tract upset.Ferritin is a protein that is found inside every cellandsbquo; and effectively stores iron for your body so it can be used at a later time. By administering a ferritin testandsbquo; the amount of iron in the blood is indirectly measured. In other wordsandsbquo; your blood or serum ferritin level is directly linked to the amount of available iron stored in your body.Lower-than-normal levels of ferritin may be the result of the following:Intestinal conditions that cause poor absorption of ironIron deficiency (anemia)Long-term digestive tract bleedingHeavy menstrual bleedingFortunatelyandsbquo; Ferritin Bioavailable Iron 5 mg by Ecological Formulas can help bring the amount of ferritin up to optimal levels.Iron is essential for good health since itandrsquo;s a part of every cell and performs many duties in the human body. For exampleandsbquo; iron serves as a part of a protein called hemoglobinandsbquo; which moves oxygen from the lungs throughout the body. Having a deficiency of hemoglobin typically results in iron deficiencies. Iron also helps the muscles use and store vital oxygen.In additionandsbquo; iron is part of many enzymesandsbquo; and is utilized in many cell functions. Enzymes help your body in the digestion of foodandsbquo; and also assist with many other important

## Questions & Answers

**Q: SO, is it from horses or cows, and what country are these animals in and what is the processing to get this supplement? what are the animals fed?**
A: I do not know the answers to those very good questions. I believe the patient should ask their doctor if taking Ferritin itself will increase serum Ferritin levels. Usually, one takes an iron supplement and that will lead to an increase in Ferritin which represent your body's stores of iron. If the patient is looking for relief of RLS...Restless Legs Syndrome...43% of RLS is caused by low Ferritin levels in the brain.       Dr. Holder

**Q: is it vegan?**
A: I wouldn't think so being from bovine spleen

**Q: What is the difference between cr bioavailable ferritin and just cr ferritin?**
A: In the small print it says bioavailable iron. I have low ferritin. I took this for one month. It did not raise my ferritin level. I am relatively certain it would be a good iron supplement. And you need iron for your body to make ferritin. Not so sure your body can absorb ferritin orally and not so sure this product contains Ferritin even though that is the name just like Half&Half is not 50/50 cream and milk. I believe this is an iron supplement.

**Q: equine or bovine????**
A: Is stated in the product description on website:  is a 5 mg iron supplement naturally isolated from bovine spleen. This scientifically-designed formula is free of corn, soy, yeast and wheat.
