A Dietician Says—Eat These 15 Vitamin C Foods to Boost Immunity


Supplements are a hot topic in the health world, and experts still disagree about their efficacy. Despite the unknowns, one vitamin in particular, tends to make it on every list of sought-after supplements due to its scientifically proven effects on the body. Whether it’s used to fight a stubborn cold or brighten your complexion, vitamin C is loved by many for its numerous health benefits. Since our bodies can’t produce this vitamin, meeting the recommended daily dosage can be tricky. Fortunately, vitamin C can be found in many of our everyday foods, making upping your intake just a bit easier.

We called in registered dietician May Zhu to break down everything you need to know about this powerful vitamin. Zhu says that it’s easiest to meet the RDA of vitamin C through food, but supplementation is available. Read on for answers on everything you might be wondering about vitamin C and 15 foods that you can find it in!

What Are the Benefits of Vitamin C?

Vitamin C doesn’t just cover one area of health. Zhu says that this vitamin can strengthen immunity, which can be particularly beneficial during cold and flu season. vitamin C can also improve iron absorption, as this process determines how efficiently our body uses energy. Stimulation of collagen production is another benefit that vitamin C reaps, which can enhance overall skin health.

Should we be taking vitamin C supplements, or getting it from whole food sources?

Zhu says, “When it comes to vitamin intake, we always recommend a food-first approach before supplementation. Vitamin C is a water-soluble vitamin which means our bodies do not store it in large amounts, so after the body absorbs what it needs, anything in excess gets flushed out.” Therefore it isn’t a good idea to over-supplement this vitamin. Zhu also shared that the current Tolerable Upper Intake Level (aka the max daily intake unlikely to cause harmful effects on health) for vitamin C is 2000 mg a day. She notes that the RDA for adults 19 years old is 90 mg (men) / 75 mg (women). For pregnancy, the amount increase from 85mg to 120 mg daily. 

Zhu says that an easier way, however, to make sure vitamin C requirements are met and not exceeded is to regularly consume it through food, ideally through fruits and vegetables. She says that consuming 1-2 fruit and vegetables in every meal can help maintain vitamin C levels in the body. However, supplements can always be considered if you have a diet that is insufficient in vitamin C or find it harder to consume fruits and vegetables regularly.

What Are Signs That You’re Deficient in Vitamin C?

Although rare, vitamin C deficiencies can occur, typically in less developed countries. However, there are warning signs of a deficiency. These may include:

  • Slow healing wounds
  • Bruising on skin 
  • Bleeding (red) gums/tooth loss
  • Weak immunity 
  • Scurvy 
  • Iron-deficiency anemia

As Zhu mentioned, the best way to meet the ideal RDA of vitamin C without going overboard is through food. This list consists of a variety of healthy and tasty options that are high in vitamin C and easy to incorporate into your weekly menu.
