Product description
This vitamin C supplement is clearly high-dose at 1,500 mg per daily dose and combines PureWay-C® with a polyphenol complex of grape seed extract, OPC, quercetin, rutin and citrus bioflavonoids. The product character therefore lies in the combination of very high vitamin C intake with accompanying plant compounds. From an orthomolecular perspective, the total dose is the central point: additional vitamin C products are usually unnecessary, and individual tolerance as well as kidney or metabolic considerations should be taken into account.

Nutrient knowledge & reference values
General nutrient information for interpreting the product dosage. Signs of insufficient or excessive intake are non-specific and do not replace a diagnosis.
Vitamin C
Vitamin C (ascorbic acid) is an essential water-soluble vitamin. presents physiological functions, the EU NRV, safety assessment and product-specific dosage separately.
Functions
EU-authorised health-claim functions include, among other things: vitamin C contributes to normal collagen formation for the normal function of blood vessels, bones, cartilage, gums, skin and teeth. It contributes to normal energy-yielding metabolism, normal functioning of the nervous system and immune system, and the protection of cells from oxidative stress. Vitamin C also contributes to the reduction of tiredness and fatigue and increases iron absorption.
Possible signs of insufficient intake
Severe vitamin C deficiency can lead to scurvy. Reported signs include fatigue, inflammation of the gums, pinpoint bleeding, increased capillary fragility and delayed wound healing. Such symptoms are not suitable for self-diagnosis.
Points to consider at high intake
EFSA was unable to derive a UL for vitamin C because of insufficient data. High additional intake can mainly cause gastrointestinal symptoms such as diarrhoea, nausea, bloating or abdominal cramps. With very high amounts, individual risk factors should be taken into account.
Special considerations
An increased risk of inadequate intake exists, among other situations, with a very one-sided diet, malabsorption and in smokers or people with substantial passive-smoke exposure. In haemochromatosis, particular caution is advisable with high-dose vitamin C because it increases non-haem iron absorption.
Interactions / caution
Vitamin C can increase non-haem iron absorption. High-dose supplementation in haemochromatosis should only be used after professional consultation. During chemotherapy or radiotherapy, high-dose antioxidant supplementation should be coordinated with the treating team.
