A medium peach provides a meaningful dose of vitamin C, covering about 15% of your daily needs, along with 6% of your daily vitamin A. Beyond those two headliners, peaches carry smaller amounts of several B vitamins, vitamin E, and vitamin K, making them a surprisingly well-rounded fruit for their modest calorie count.
Vitamin C: The Standout
Vitamin C is the most abundant vitamin in a peach. One medium fruit (about 147 grams) delivers roughly 10 milligrams, which accounts for 15% of the recommended daily value. That won’t rival an orange, but it’s a solid contribution, especially if you’re eating peaches alongside other fruits and vegetables throughout the day. Vitamin C supports your immune system, helps your body absorb iron from plant foods, and plays a direct role in producing collagen, the protein that keeps skin firm and wounds healing properly.
Peaches also contain polyphenols, plant compounds that work alongside vitamin C as antioxidants. Together, these compounds fight cell damage linked to aging, heart disease, and certain cancers. The Cleveland Clinic notes that the polyphenols in peaches can decrease inflammation, which lowers the risk of chronic conditions including diabetes and Alzheimer’s disease.
Vitamin A and Beta-Carotene
The yellow-orange color of a peach comes from beta-carotene, a pigment your body converts into vitamin A. One medium peach supplies about 6% of your daily vitamin A requirement. That matters most for your eyes. Vitamin A is essential for healthy vision, particularly your ability to see in low light. It also supports immune function and helps maintain the lining of your lungs, gut, and other tissues that act as barriers against infection.
Yellow-fleshed peaches tend to be richer in beta-carotene than white-fleshed varieties. If you’re choosing peaches partly for their vitamin A content, the deeper the color, the more beta-carotene you’re getting.
B Vitamins in Peaches
Peaches contain small but useful amounts of several B vitamins. Niacin (B3) helps your body convert food into energy and keeps your skin and nervous system functioning. Folate (B9) is critical for cell division and DNA synthesis, making it especially important during pregnancy. A single peach won’t cover a large percentage of your daily B vitamin needs on its own, but these contributions add up across a varied diet.
Thiamine (B1) and riboflavin (B2) are also present in trace amounts. These support energy metabolism and help maintain healthy red blood cells.
Vitamin E and Vitamin K
Peaches provide modest amounts of both vitamin E and vitamin K. Vitamin E is a fat-soluble antioxidant that protects cell membranes from damage, particularly in your skin and eyes. Vitamin K plays a role in blood clotting and bone health. Neither vitamin appears in large quantities in peaches, so think of them as bonus nutrients rather than primary sources.
Key Minerals That Work With These Vitamins
Vitamins don’t work in isolation, and peaches come packaged with minerals that complement their vitamin content. A small peach contains about 150 milligrams of potassium, which helps regulate blood pressure and supports muscle and nerve function. It also provides around 7 milligrams of magnesium, a mineral involved in hundreds of enzyme reactions including energy production and muscle contraction. Small amounts of phosphorus and copper round out the mineral profile.
Potassium is worth highlighting because most people fall short of the recommended daily intake (around 2,600 to 3,400 milligrams depending on age and sex). Snacking on a peach or two throughout the day chips away at that gap.
Fresh, Frozen, and Canned Differences
You might assume fresh peaches always win nutritionally, but the picture is more nuanced. Researchers at the Linus Pauling Institute found that canned peaches were actually higher than fresh in vitamin C, folate, and total antioxidants. The likely explanation: fresh peaches start losing nutrients the moment they’re picked, and the time between harvest and your kitchen can stretch to days or weeks. Canned peaches are processed quickly after picking, which locks in nutrients.
Frozen peaches tell a similar story. They’re picked at peak ripeness and frozen shortly after, so their nutritional content closely mirrors fresh peaches. The main thing to watch with canned peaches is added sugar. Choose varieties packed in water or their own juice rather than heavy syrup, and you’ll get the vitamin benefits without the extra calories.
How Peaches Compare to Other Stone Fruits
- Nectarines are genetically almost identical to peaches (the main difference is a single gene controlling fuzz). Their vitamin profiles are nearly interchangeable, though nectarines tend to have slightly more vitamin C and potassium.
- Plums contain less vitamin C than peaches but are richer in vitamin K.
- Apricots pack significantly more vitamin A per serving, roughly double what a peach offers, thanks to their deeper orange color and higher beta-carotene concentration.
- Cherries are lower in both vitamin C and vitamin A compared to peaches but higher in certain anti-inflammatory compounds.
If you’re eating a mix of stone fruits through the summer, you’re covering a broader range of vitamins than any single fruit would provide on its own. Peaches hold their own in that lineup, offering the best balance of vitamin C and vitamin A among the group.
