How are we different?

Our Vitamin C Ultra consists exclusively of the ultra-pure active ingredient PureWay-C®. This premium raw material offers a unique, synergetic combination of ingredients which allow significantly higher vitamin C absorption than conventional preparations; due to the combination of plant-based fatty acids and a citrus bioflavonoid complex, the vitamin C can be better absorbed into the blood and cells and has a longer retention time. This combination also protects against oxidation and is responsible for the product's long shelf life.

Another factor influencing the quality of vitamin C supplements is the source of the vitamin itself; high-dose vitamin C is obtained almost exclusively from corn and citrus fruits, the quality of which can vary. It is therefore important to us to ensure that the raw material is sourced exclusively from non-GMO corn. This raw material, through the highly innovative and modern PureWay-C® manufacturing process conducted according to the highest quality standards, is transformed into our concentrated active ingredient—and contains no trace of corn, fructose or any chemical solvent residues.

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 then package this product in environmentally friendly amber glass.

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:

Health Benefits of Vitamin C

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


Recommended Dosage

Take 1 capsule (950mg vitamin C + 40mg bioflavonoids and lipids) daily with 200ml water.

Daily Requirements

The German Nutrition Society (DGE) recommends an intake of 100mg vitamin C per day. The recommended daily intake according to the European Food Safety Authority (EFSA) is 80mg.

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.


Store in a cool, dry place away from direct sunlight and heat (ideally in the refrigerator).
