How are we different?
The vitamin C in our Sun-C® sustained-release formula is microencapsulated in fatty acids, meaning it is embedded in tiny microcapsules that protect it from stomach acid. This technology ensures that vitamin C is not released all at once, but is instead made available to the body gradually over an extended period. Sun-C® Sustained-Release Vitamin C ensures a controlled, delayed release over 8 hours.
Since vitamin C levels drop relatively quickly after intake and the body can only absorb a limited amount at one time, the constant release of vitamin C from this formula supports a steady supply.
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 use environmentally friendly amber glass for the packaging of this product.

Effects
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 cognitive function
- The regeneration of the reduced form of vitamin E
- Normal energy metabolism
- Normal immune system functioning
- Normal nervous system functioning
- The protection of cells from 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 functioning of the immune system both during and after intense physical activity.
Dosage
Dosage
Directions
Take 2 capsules daily with 200ml water with a meal.
Daily Requirements
The German Nutrition Society (DGE) recommends a daily intake of 100mg of vitamin C. The recommended daily dose according to the EFSA is 80mg.
Vitamin C should be taken in several doses throughout the day or in sustained-release form, as the level of vitamin C in the blood drops relatively soon after intake and the body can only absorb a certain amount into the tissue at a time (saturation).
Contraindications
Not suitable for children or those who are pregnant or breastfeeding. Discontinue use if a laxative effect occurs.
Food Supplement
Do not exceed the recommended daily intake. Food supplements are not a substitute for a balanced, varied diet and healthy lifestyle. Keep out of reach of young children.
Storage
Store in a cool, dry place away from direct sunlight and heat.
