How Much Calcium Is In An Apple? A Surprising Answer

You probably assume an apple is a decent source of calcium. The fruit’s reputation as a health powerhouse runs deep, and minerals are part of that story. But the calcium content in an apple is surprisingly low compared to other common foods.

This article breaks down exactly how much calcium an apple provides, how it stacks up against other fruits and dairy sources, and why the number matters for your daily intake. The short version: apples are not a meaningful source of dietary calcium, and the research on that is consistent across all sources.

Exactly How Much Calcium A Medium Apple Provides

A medium apple weighing about 182 grams contains roughly 10.9 mg of calcium, according to nutrition databases. Per 100 grams, that works out to about 5 mg of calcium — a very small amount.

The International Osteoporosis Foundation provides a similar figure, noting that a 120-gram serving of apple contains about 6 mg of calcium. A typical Pink Lady apple (152 grams) comes in at around 8 mg, reflecting minor size-based differences.

These numbers place apples firmly among the lowest-calcium fruits available. For context, a medium banana (150 grams) provides about 12 mg of calcium — still low, but slightly more than an apple of similar size.

Why People Assume Apples Contain More Calcium

The misconception probably comes from apples being lumped into the “healthy fruit” category alongside genuinely calcium-rich options like oranges, kiwifruit, and dried figs. Many fruits offer meaningful mineral content — apples just aren’t one of them for calcium.

Another factor is the association between apples and general health. When you think of an apple’s nutritional profile, you likely think of fiber and vitamin C first. Those are real benefits. Calcium simply isn’t part of the story.

The key takeaway: apples are a low-calcium food. They provide less than 1% of the daily value for calcium per serving. If you’re relying on apples for calcium, you’d need to eat several dozen to make a dent in your daily needs.

Are There Differences Between Apple Varieties?

The calcium content in apples varies slightly depending on the cultivar. York Imperial apples show noticeably lower calcium levels compared to other varieties, per horticultural research. A 2023 study found calcium is most concentrated in the peel and lowest in the flesh — so eating the peel helps maximize whatever calcium is there.

Calcium uptake in apple fruit is most efficient at the fruitlet stage (early development), which explains why growers interested in preventing bitter pit — a calcium-deficiency disorder in the fruit — apply calcium sprays early in the season. Penn State Extension’s calcium for bitter pit prevention recommends 9 to 11 pounds of actual calcium per season for susceptible cultivars.

Apple Type	Serving Size	Calcium (mg)
Medium apple (generic)	182 g	10.9
Per 100 g (generic)	100 g	5.0
Pink Lady	152 g	8.0
Per IOF standard	120 g	6.0
Banana (for comparison)	150 g	12.0

The differences between varieties are small enough that they don’t change the overall picture. No apple variety approaches even 5% of the daily value for calcium per serving.

How Apples Compare To Other Calcium Sources

The gap between apples and calcium-rich foods is enormous. A cup of milk (244 grams) contains about 300 mg of calcium — roughly 27 times more than a medium apple. A 30-gram serving of parmesan cheese delivers 300 mg of calcium, about 30 times the calcium in a whole apple.

Fruits that are genuinely high in calcium include calcium-fortified orange juice, prickly pears, tangerines, oranges, kiwifruit, mulberries, blackberries, guavas, papaya, and dried figs. All of these contain significantly more calcium per serving than apples.

1. Dairy products: Milk, yogurt, and cheese are the most concentrated dietary calcium sources.
2. Fortified foods: Calcium-fortified orange juice, plant milks, and cereals provide 200–350 mg per serving.
3. Leafy greens: Kale, collard greens, and bok choy offer 100–200 mg per cooked cup.
4. Fish with bones: Canned sardines and salmon provide 200–300 mg per serving.

Apples sit near the very bottom of this list. They are a healthy fruit for many reasons — fiber, vitamin C, antioxidants — but calcium is not among their strengths.

Should You Worry About Apples And Calcium?

No. Apples are not a calcium source, but they also don’t interfere with calcium absorption. Some foods contain oxalates or phytates that can bind calcium and reduce its absorption, but apples are not significant in either compound.

The bigger picture: a whole-food diet that includes apples alongside dairy, leafy greens, and fortified products easily meets calcium needs. The calcium content of an apple is so low that it’s essentially a non-factor in your daily mineral intake — the same database shows that a glass of milk provides about 27 times more calcium per serving.

Apples do contain other important minerals like potassium, phosphorus, and magnesium (about 4 mg magnesium and 8 mg phosphorus per 100 grams). These are real contributions, just not for calcium.

Food	Serving	Calcium (mg)
Medium apple	182 g	10.9
Medium banana	150 g	12.0
1 cup milk	244 g	300
30 g parmesan	30 g	300
Fortified OJ	240 ml	300

If you enjoy apples, keep eating them. They offer real nutritional value. Just don’t count on them for your daily calcium target.

The Bottom Line

A medium apple provides about 11 mg of calcium — less than 1% of the daily value. That’s roughly the same amount as a medium banana and far below any dairy product, fortified food, or leafy green. Apples are not a meaningful source of calcium, and no variety changes that fact. Focus on dairy, fortified foods, and greens for your calcium needs; enjoy apples for their fiber, vitamin C, and crisp texture.

If you’re tracking your calcium intake for bone health or a specific dietary goal, your doctor or a registered dietitian can help match your actual servings from dairy, leafy greens, and fortified foods to your individual daily target.
