Cvitamiinipitoinen

C-vitamiinipitoinen is a Finnish term used to describe foods or diets that contain a high amount of vitamin C (ascorbic acid). It is commonly applied in nutrition guidance to indicate sources rich in this nutrient and to distinguish them from low‑vitamin C alternatives.

Vitamin C is a water‑soluble antioxidant that supports collagen synthesis, wound healing, and iron absorption, and it participates in various metabolic processes. It also contributes to immune function and protects cells from oxidative stress. Since humans cannot synthesize vitamin C, it must be obtained through the diet.

Foods described as C-vitamiinipitoinen typically include citrus fruits, berries, peppers, and leafy greens. Common examples are oranges, kiwis, strawberries, bell peppers, broccoli, and Brussels sprouts. The exact vitamin C content varies by food and preparation method; raw or minimally processed products generally retain more vitamin C than heavily cooked ones.

Daily requirements for adults are about 75–90 mg, with higher needs during certain life stages or conditions. A balanced, varied diet that emphasizes fruit and vegetable intake usually provides sufficient vitamin C. Very high intakes from supplements are not necessary for most people and can cause gastrointestinal discomfort.

In dietary labeling and planning, describing a product or meal as C-vitamiinipitoinen signals its potential contribution to meeting daily vitamin C needs. See also vitamin C and nutrient density.
