How are we different?
Vitamin C doesn't occur in nature as an isolated, standalone compound. It's always embedded within a rich matrix of various plant polyphenols and other phytochemicals. Through their own antioxidant activity, these compounds not only create a vitamin C-sparing, synergistic effect, but also influence the vitamin's bioavailability and retention time.
Our Vitamin C Complex Ultra plus Bioflavonoids delivers vitamin C within a distinctively rich multi-spectrum complex. It combines fruit powders from acerola cherries, camu camu, rosehip and masson pine bark, each retaining its own characteristic phytochemical profile, with vitamin C from the branded active ingredients PureWay-C® and Polyphenol-C®. This is further enriched with plant-based fatty acids, citrus bioflavonoids and berry polyphenols from grape, raspberry, blackberry, strawberry and cranberry. Quercetin, rutin and OPC from grape seed and pine bark are well known for their close synergy with vitamin C, while lesser-known phytochemicals, such as the citrus bioflavonoids hesperidin, naringin, apigenin and naringenin, also support vitamin C's effectiveness.
The natural vitamin C sources, acerola, camu camu and rosehip, are included as whole fruit powders. Quercetin, rutin and OPC are obtained through pure extraction using water or a water/ethanol mix (food grade), without the use of any chemical solvents.
For obtaining vitamin C in high doses, almost exclusively maize or citrus fruits are used, and here too, quality can vary considerably. We placed great importance on sourcing only non-GMO maize as a raw material. This is processed using a state-of-the-art, innovative manufacturing method to the highest quality standards, resulting in the branded active ingredient PureWay-C®. The end result is highly concentrated vitamin C that's completely free of maize residue, fructose-free and free from chemical solvent residues.
Polyphenol-C® is a premium vitamin C complex combining vitamin C with a standardised 10% polyphenol content sourced from a broad spectrum of fruit and berry powders/extracts (blueberry, grape, raspberry, blackberry, strawberry, cranberry). This premium active ingredient was designed to mirror nature itself: in fruits and berries, vitamin C naturally occurs alongside anthocyanins, proanthocyanidins and bioflavonoids as natural cofactors.
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
Vitamin C is involved in numerous redox reactions as an antioxidant and cofactor, thus influencing numerous processes in the human body, such as energy metabolism and the immune system, and providing antioxidative protection to cells. It is also involved in the formation of collagen, the structural protein found in skin, cartilage, bones and blood vessels, as well as in the synthesis of hormones.
High concentrations of vitamin C are found naturally in fresh fruits, vegetables and berries such as camu camu, sea buckthorn berry, acerola cherry, rosehip, black currant, kale, parsley, kiwis and citrus fruits, among others.
The role of vitamin C in the body remains an active area of research. Almost every year, new mechanisms of action are discovered for this fascinating vitamin. The following statements regarding vitamin C are provided by the EU:
According to the European Food Safety Authority (EFSA):
Vitamin C contributes to:
- The reduction of tiredness and fatigue
- Normal mental function
- The regeneration of the reduced form of vitamin E
- Normal energy metabolism
- Normal immune system function
- The normal function of the nervous system
- Protecting cells against oxidative stress
- Normal collagen formation for normal blood vessel function
- Normal collagen formation for normal bone function
- Normal collagen formation for normal cartilage function
- Normal collagen formation for normal dental function
- Normal collagen formation for normal gum function
- Normal collagen formation for normal skin function
- Increasing iron absorption
- Maintaining normal immune system function both during and after intense physical activity
Synergy with Bioflavonoids
Bioflavonoids are the most common type of phytochemical. These important compounds are found in vegetables, fruits and herbs and are responsible for the vibrant colour of blueberries and of dark leafy vegetables, to name a couple examples. Bioflavonoids have strong antioxidant properties; to support the natural synergy between vitamin C and bioflavonoids, our vitamin C complexes contain a broad spectrum of valuable bioflavonoids from citrus fruits, berries and superfoods which themselves are also rich in vitamin C.
Acerola
Our acerola is sourced from Brazil. It is gently freeze dried immediately after harvest and then milled into a natural fruit powder without the addition of controversial carrier materials such as maltodextrin. Acerola cherries are known for their exceptionally high vitamin C content (approximately 1700mg per 100g fresh).
Camu Camu
The small, yellowish red camu camu fruit (Myrciaria dubia) grows wild in the Peruvian Amazon. The fruity and sour, slightly bitter berries are among the most vitamin C-rich foods on earth, with roughly 40 times the vitamin C of an orange. The dried berry can reach up to 13–14% vitamin C.
Rosehip
We source our premium rosehip powder from Chile, where the variety of rosehip (Rosa canina L.) richest in bioactives thrives. The wild bushes grow slowly under the harsh climatic conditions in the south of Chile at an altitude of 800m. This slow growth fosters the development of a uniquely high quality fruit. Hildegard von Bingen considered rosehip to have special healing properties.
Rutin and Quercetin
Yellow-coloured rutin as well as quercetin are bioflavonoids. Rutin is the glycosidic compound of quercetin, supplemented by the disaccharide rutinose. Like all flavonoids, rutin and quercetein have antioxidant properties, which is why plants increase their production of them under certain conditions: they need rutin and quercetin for colour and protection (e.g., to protect themselves against UV rays or environmental influences). The blossoms of the Japanese cord tree (Sophora japonica), from which we extract our rutin and quercetin, are particularly rich in these phytochemicals.
OPC Complex
OPC (short for oligomeric proanthocyanidins), also known as vitamin P, are a group of flavonols consisting of polymers of catechins and epicatechins. OPCs are found in high concentrations in grape seeds and pine bark, each of which also contain other valuable phytochemicals. The individual proanthocyanidins contained in each differ in both form and effect. Grape seed extract contains significant quantities of the important proanthocyanidin B3-3-O-gallate, while pine bark extract contains taxifolin. Together, the extracts offer the full spectrum of the OPC group.
Dosage
Recommended Dosage
Take 1 capsule (400mg vitamin C) daily.
Daily Requirements
The National Health Service (NHS) recommends a daily intake of 40mg of vitamin C. However, it is important to note that individual vitamin C needs may vary according to age, dietary habits, genetics and other factors.
Vitamin C should be divided into several portions throughout the day, as the body can only absorb a limited amount into its tissues at once before they reach saturation and because blood levels of the vitamin drop relatively soon after ingestion.
Food Supplement
Do not exceed the recommended dose. Food supplements cannot replace a balanced and varied diet. Keep out of reach of children. Not suitable for children, adolescents or individuals who are pregnant or breastfeeding.
Storage
Store in a cool, dry place away from direct sunlight and heat.

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.
