Carbonyl Iron is an ideal source of essentially pure iron with low toxicity, minimal metallic taste, no gastro-intestinal pain nor constipation and excellent bioavailability of 69%.

Thus, it is the better choice for iron supplementation.

Carbonyl Iron powder is metallic iron (Fe) with high (> 98%) iron content. It is not a salt.

It absorbes at 69%, compared to only 10 to 15% with most other forms of iron.

The high iron content and high absorption rate results in lower dose per capsules, achieving the same or better daily intake levels, compared to ferrous (Fe2+) salts (e.g., ferrous sulfate, ferrous fumarate, or ferrous gluconate),
while at the same time and most importantly, side effects like constipation and gastro-intestinal discomfort and pain are avoided.

In addition to the high iron content, a key physical property of Carbonyl Iron is its fine spherical particle size and porousity with huge surface area, both resulting in higher human bioavailability than other iron forms.

Carbonyl Iron is far less toxic than soluble iron salts, it causes fewer side effects.

With its low dose level, excellent bioavailability and low toxicity, Carbonyl Iron is a better choice for iron supplementation.

With greater than 98% iron, Carbonyl Iron has a much higher iron content than ferrous salts, such as ferrous gluconate, ferrous sulfate and ferrous fumarate (Table 2).
As a result, substantially less Carbonyl Iron is required to reach the same unit dose than a ferrous salt, resulting in lesser side effects.

The amount of iron absorbed by the body per unit dosage from a particular iron source is a function of several factors: particle size, surface area, ionic charge, iron content.

The first three of these factors contribute to the relative biological value (RBV) of the iron source -  a measure of how quickly the iron enters the blood stream.

Table 1 shows that the high iron absorption from Carbonyl Iron results from its small particle size, which contributes to a higher RBV than other forms of elemental iron, and its high iron content relative to ferrous sulcate.

    No side effects, increasing energy

    Zero side effects taking two capsules per day, on an empty stomach. No constipation or nausea, which I had dealt with before with other sources.
    I have only been taking it a few days now, but I feel my energy and motivation is slightly increased already, and I'm looking forward to having my levels checked again in a few months! Hoping this will get my ferritin up to a more "ideal" number!
