How are we different?
According to current research, iron bisglycinate is the iron compound with the highest bioavailability. In this form, the mineral iron is bound to the amino acid L-glycine, allowing it to be absorbed exceptionally well by the body. While glycine occurs naturally in nuts, soya beans and lentils, it cannot be isolated from these sources in significant quantities. For this reason, we use pharmaceutical-grade, highly pure glycine and iron bisglycinate for our high-strength iron capsules. We have chosen a high-purity synthetic iron bisglycinate produced in Germany, which makes our high-strength formulation not only exceptionally well-tolerated but also suitable for vegans and vegetarians.
Additionally, the inclusion of vitamin C enhances iron absorption. Our vitamin C is derived from non-GMO maize through a specialised manufacturing process and is maize-free in the final product. This ensures a concentration of nearly 100% (at least 99.8%) and a high level of purity.
The raw materials were produced in Germany and the USA in accordance with the most stringent purity and quality standards.
For the capsule shells we use custom-made HPMC capsules that, unlike most other HPMC and pullulan capsules on the market, are 100% free from controversial additives such as carrageenans and PEG. We package this product in amber glass jars instead of plastic to protect the ingredients from light.
Our commitment to uncompromising quality & purity:
- Premium active ingredients as pure isolates & directly sourced from leading global producers
- All formulations crafted exclusively from selected individual raw materials
- Our commitment: zero unnecessary additives, technical excipients or chemical extraction agents
- Voluntary declaration of all non-mandatory ingredients
- Where additives are necessary, preference is given to valuable natural ingredients
- Capsule shells entirely free from carrageenan & PEG
- Systematic quality testing conducted by independent laboratories
- Packaged in amber glass or premium aroma-protective zipper bags designed to protect against oxidation & contaminants
- All products entirely free from magnesium stearate, nanoparticles (without legal exceptions), GMOs, artificial colours & flavours, titanium dioxide
- Added sugar & sweeteners: used only where required for functional or product-specific reasons
Effects
Iron is an essential trace element that plays a vital role in oxygen transport in the blood, cellular respiration, the maintenance of the immune system and normal cognitive performance.
High Bioavailability: Iron Combined with Vitamin C
Iron from plant-based sources is typically less biovailable to humans than that from animal sources. This is due to the phytic acid produced by iron-rich plants, a compound that inhibits mineral absorption. The combination of an organic iron chelate, bound to the amino acid L-glycine, with vitamin C results in a non-animal-derived source of iron with high bioavailability.
According to the European Food Safety Authority (EFSA):
Iron contributes to:
- Normal cognitive function
- Normal energy metabolism
- Normal formation of red blood cells and hemoglobin
- Normal oxygen transport
- Normal function of the immune system
- Reduction of tiredness and fatigue
- Iron plays an important role in cell division

Product Details
Our in-house production guarantees uncompromising purity and quality. Production, bottling and encapsulation take place in the EU according to our own rigorous specifications and in strict compliance with HACCP, GMP and ISO 22000:2018 standards.
Bespoke liquid formulations, (functional) foods for athletic and daily performance and select exclusive items are produced as high-grade custom preparations by chosen partners who share our commitment to quality, adhering strictly to HACCP, GMP and ISO standards.
In line with our True Clean Label philosophy, we refrain from using artificial additives, colourants and preservatives intended to standardise product appearance. Consequently, formulations containing natural botanical extracts and plant-based raw materials may display subtle batch-to-batch colour variations. These variations stem from natural factors such as harvest timing (seasonal differences between early and late harvests), origin (geographical soil and climate fluctuations) or processing dynamics (variations in particle grind size). Such natural shade shifts may also occur in our plant-based or compressed tablets formulated with premium acacia fibre or nanoparticle-free cellulose and do not constitute a defect in quality.
Laboratory Tests
The purity of our formulas is important to us. This is why we have both our raw ingredients as well as our finished products extensively tested by independent laboratories to confirm purity and active ingredient content. Here, we have provided the results of some of the tests carried out on this product.
