Cheddar cheese is a popular source of protein, calcium, and rich flavor, but it is not a vitamin C food. According to USDA nutrition data, cheddar contains 0 mg of vitamin C per 100 g, regardless of whether it is sharp, mild, reduced-fat, or aged. That makes this calculator quick: any serving of cheddar contributes zero vitamin C to your daily intake.
This tool converts your cheddar serving into grams, applies the standard 0 mg per 100 g value, and shows your result as milligrams and percent Daily Value (DV, based on 90 mg). You can also select a comparison food such as orange, broccoli, strawberry, or tomato to see how much vitamin C the same weight of that food would provide.
Whether you are tracking micronutrients, meal planning, or just curious about your cheese board, this calculator gives you a clear, honest answer in seconds.

What This Calculator Tells You
This calculator starts from one simple fact confirmed in the USDA FoodData Central database: cheddar cheese contains 0 mg of vitamin C per 100 g. Whether you measure your serving in grams, ounces, cups of shredded cheese, or slices, the vitamin C result is always 0 mg and 0% of the Daily Value. The tool still does a real conversion of your portion size, so you can see exactly how much cheddar you are eating and confirm that none of that weight contributes vitamin C.
Why is the result always zero? Vitamin C is water-soluble and found almost exclusively in plant foods. Milk contains very little vitamin C to begin with, and the cheesemaking process drains away most of the watery whey where any remaining vitamin C would be. By the time cheddar is aged and pressed, the vitamin C content is effectively gone.
How the Calculation Works
The formula is simple: vitamin C (mg) = serving weight (g) × 0 mg ÷ 100 g = 0 mg. The percent Daily Value is then 0 mg ÷ 90 mg × 100 = 0%. The only real math in this calculator is converting your chosen unit into grams. One ounce equals 28.35 g, one cup of shredded cheddar weighs about 113 g, and one slice is assumed to weigh 28 g. The comparison feature uses the same weight conversion and multiplies it by the vitamin C density of the selected food, such as 53.2 mg per 100 g for oranges or 89.2 mg per 100 g for cooked broccoli.
Worked example 1: Enter 113 g of shredded cheddar. The calculator converts the serving to 113 g, multiplies by 0 mg per 100 g, and returns 0 mg — 0% of the 90 mg DV. The comparison feature then shows that the same 113 g of orange would provide about 60 mg of vitamin C.
Worked example 2: Enter 2 oz of cheddar. The calculator converts it to 56.7 g, applies the same 0 mg per 100 g value, and still returns 0 mg. The comparison box shows that 56.7 g of cooked broccoli would provide about 50.6 mg of vitamin C.
Comparison Examples
The comparison dropdown is included to put the zero result in context. Instead of only telling you what cheddar lacks, it shows what the same weight of a vitamin C-rich food would give you. This perspective is useful when planning a cheese board, packing a lunch, or deciding whether a snack genuinely contributes to your daily micronutrient target.
- Orange: 53.2 mg per 100 g, so a 100 g serving provides 59% of the Daily Value.
- Broccoli (cooked): 89.2 mg per 100 g, so a 100 g serving provides 99% of the Daily Value.
- Strawberries: 58.8 mg per 100 g, so a 100 g serving provides 65% of the Daily Value.
- Tomato: 13.7 mg per 100 g, so a 100 g serving provides 15% of the Daily Value.
Daily Value Reference
The FDA sets the Daily Value for vitamin C at 90 mg for adults. This is the reference amount used on Nutrition Facts labels in the United States. The table below shows how cheddar compares with common vitamin C sources per 100 g.
| Food (per 100 g) | Vitamin C | % DV (90 mg) |
|---|---|---|
| Cheddar cheese | 0 mg | 0% |
| Orange | 53.2 mg | 59% |
| Broccoli (cooked) | 89.2 mg | 99% |
| Strawberries | 58.8 mg | 65% |
| Tomato | 13.7 mg | 15% |
Frequently Asked Questions
Does cooking or aging cheddar change its vitamin C content?
No. Vitamin C is destroyed by heat and exposure to air, so any trace amount that survived cheesemaking would decline further during aging. Fresh cheese, aged cheese, and reduced-fat cheddar all test at 0 mg per 100 g.
Is cheddar a good source of other vitamins?
Yes. Cheddar is rich in calcium, protein, vitamin A, vitamin B12, and phosphorus. It simply lacks vitamin C, which is why pairing cheese with fruit, peppers, or leafy greens makes a balanced snack.
Why does my nutrition label say something different?
Some brands may list 0 mg of vitamin C, which is correct. If a label shows a small nonzero value, it is usually rounded from a lab test of a specific batch. For practical planning, assume cheddar provides no vitamin C.
What should I eat instead to get vitamin C?
Good sources include oranges, kiwi, strawberries, broccoli, bell peppers, Brussels sprouts, and tomatoes. A single medium orange provides roughly 70 mg, close to the full Daily Value.
