Vitamin C is a water-soluble vitamin that’s found in many foods, particularly fruits and vegetables.
It’s well known for being a potent antioxidant, as well as having positive effects on skin health and immune function.
It’s also vital for collagen synthesis, connective tissue, bones, teeth and your small blood vessels (Trusted Source).
The human body cannot produce or store vitamin C. Therefore, it’s essential to consume it regularly in sufficient amounts.
The current daily value (DV) for vitamin C is 90 mg.
Deficiency symptoms include bleeding gums, frequent bruising and infections, poor wound healing, anemia and scurvy (Trusted Source).
Here are the top 18 foods that are high in vitamin C.
1. Kakadu Plums

One-half cup (56 grams) of blackcurrants (Ribes nigrum) contains 101 mg of vitamin C, or 112% of the DV.
Antioxidant flavonoids known as anthocyanins give them their rich, dark color.
Studies have shown that diets high in antioxidants like vitamin C and anthocyanins may reduce oxidative damage associated with chronic diseases, including heart disease, cancer and neurodegenerative diseases (Trusted Source, Trusted Source).
Two tablespoons (8 grams) of fresh parsley contain 10 mg of vitamin C, providing 11% of the recommended DV.
Along with other leafy greens, parsley is a significant source of plant-based, non-heme iron.
One two-month study gave people on a vegetarian diet 500 mg of vitamin C twice a day with their meals. At the end of the study, their iron levels had increased by 17%, hemoglobin by 8% and ferritin, which is the stored form of iron, by 12% (Trusted Source).
9. Mustard Spinach
One cup of raw chopped mustard spinach provides 195 mg of vitamin C, or 217% of the DV.
Even though heat from cooking lowers the vitamin C content in foods, one cup ofcooked mustard greens still provides 117 mg of vitamin C, or 130% of the DV.
As with many dark, leafy greens, mustard spinach is also high in vitamin A, potassium, calcium, manganese, fiber and folate.
Kale is a cruciferous vegetable.
One cup of chopped raw kale provides 80 mg of vitamin C, or 89% of the DV. It also supplies high quantities of vitamin K and the carotenoids lutein and zeaxanthin.
One cup of cooked kale provides 53 mg, or 59% of the DV for vitamin C.
While cooking this vegetable reduces its vitamin C content, one study found that boiling, frying or steaming leafy greens helps release more of their antioxidants. These potent antioxidants may help reduce chronic inflammatory diseases (Trusted Source).
One medium kiwi packs 71 mg of vitamin C, or 79% of the DV (35).
A study in 30 healthy people aged 20–51 found that eating 2–3 kiwis every day for 28 days reduced blood platelet stickiness by 18% and lowered triglycerides by 15%. This may reduce the risk of blood clots and stroke (Trusted Source).
Another study in 14 men with vitamin C deficiency found that eating two kiwis daily for four weeks increased white blood cell activity by 20%. Blood levels of vitamin C normalized after just one week, having increased by 304% (Trusted Source).
Broccoli is a cruciferous vegetable. One-half cup of cooked broccoli provides 51 mg of vitamin C, or 57% of the DV.
Numerous observational studies have shown a possible association between eating plenty of vitamin-C-rich cruciferous vegetables and lowered oxidative stress, improved immunity and a decreased risk of cancer and heart disease.
One randomized study gave 27 young men who were heavy smokers a 250-gram serving of steamed broccoli containing 146 mg of vitamin C every day. After ten days, their levels of the inflammatory marker C-reactive protein had decreased by 48% (Trusted Source).
13. Brussels Sprouts
One-half cup of cooked Brussels sprouts provides 49 mg, or 54% of the DV for vitamin C.
Like most cruciferous vegetables, Brussels sprouts are also high in fiber, vitamin K, folate, vitamin A, manganese and potassium.
Both vitamins C and K are important for your bone health. In particular, vitamin C aids the formation of collagen, which is the fibrous part your bones.
