Iron Deficiency
Low iron stores often don’t become apparent until your energy levels have already started to drop. An unbalanced diet, intense workouts, or increased demand during certain life stages can cause an iron deficiency and noticeably impair your quality of life. Here you’ll find an innovative solution that goes beyond conventional iron supplements: Natural Iron CLN® combines the power of nature with modern nutritional science to efficiently support your iron supply.
Quality Without Compromise
Iron Intake in Daily Life: Energy, Performance, and Well-Being
Iron is an essential trace element that the body needs for numerous vital processes. Since we cannot produce iron on our own, a regular intake through diet or targeted supplementation is crucial, especially during demanding life stages. As a key building block, iron supports the body in many ways:
- Energy & Vitality: Contributes to normal energy metabolism and helps reduce tiredness and fatigue.
- Oxygen Transport: Supports the normal formation of red blood cells and hemoglobin for oxygen transport in the body.
- Immune System & Focus: Contributes to the normal functioning of the immune system and to normal cognitive function.
- Cell health: Iron plays an important role in cell division.
Getting enough iron isn’t always a given in everyday life. An unbalanced diet or personal health challenges can make iron intake a greater priority. In particular, gastrointestinal disorders or other issues with nutrient absorption can lead to iron deficiency even when iron intake is sufficient. Women, athletes, and people following a vegetarian or vegan lifestyle, in particular, pay close attention to their iron intake to maintain their daily performance and overall well-being.
Why Bioavailability Is Crucial in Iron Supplements
When choosing the right iron supplement, it’s not just the dosage that matters, but above all the bioavailability—that is, how well your body can absorb the iron. Plant-based sources of iron are becoming increasingly important, as they are often considered a particularly well-tolerated alternative to traditional iron salts.
To further optimize absorption in the body, modern formulations rely on the synergistic effects of vitamin C. This vitamin naturally boosts iron absorption and makes supplementation more effective. In this way, a simple intake becomes a well-thought-out nutritional strategy that integrates seamlessly into daily life.
The Next Generation of Iron Supplementation: Focus on Lactoferrin
An innovative approach in modern micronutrient research is supplementation with functional proteins such as lactoferrin. This unique iron-binding glycoprotein occurs naturally in the body, where it is valued for its role in iron transport.
In an advanced iron formulation, high-purity lactoferrin serves as a valuable component: it complements the combination of plant-based iron and vitamin C to form a comprehensive complex. The result is a highly specialized formula that provides a smart solution to the demands of modern iron supplementation.
Background information on Iron Deficiency
Plant-based iron with vitamin C to aid iron absorption
Our Natural Iron CLN® is based on a modern combination of plant-based iron and natural vitamin C. At its core is FerroPlant®, a special curry leaf extract derived from the leaves of the curry leaf tree, which serves as a plant-based source of iron. For many users, this is a more easily tolerated alternative to traditional iron compounds such as iron sulfate.
The formula is supplemented with natural vitamin C from rose hips. Vitamin C plays a key role in our supplement, as it has been shown to increase iron absorption, thereby ensuring that the plant-based iron can be utilized more efficiently by the body. Beyond simply promoting absorption, vitamin C supports normal energy metabolism and the normal function of the immune system. Especially during demanding periods, vitamin C’s ability to help reduce tiredness and fatigue is particularly valuable, which perfectly rounds out the nutritional profile of Natural Iron.
Lactoferrin as a functional ingredient in iron supplements
In addition to plant-based iron and natural vitamin C, Natural Iron also contains highly purified CLN®-grade lactoferrin. Lactoferrin is a multifunctional whey protein that occurs naturally in our bodies and has a special affinity for iron. In our formula, we use highly purified CLN®-grade lactoferrin (98% purity) as a targeted, functional partner for plant-based iron. Thanks to its natural ability to bind iron ions, lactoferrin complements the product concept in a physiological way.
While vitamin C enhances iron absorption, lactoferrin complements this profile with its specific binding capacity. Since the product is also listed on the Kölner Liste®, it offers the highest level of safety for an active lifestyle. The lactose- and gluten-free formulation also ensures that lactoferrin remains an effective choice for functional supplementation, even for those with sensitive digestion.
