How Much Magnesium Is In Pistachios? | Per Ounce & 100g

Pistachios pack a steady dose of magnesium along with protein, fiber, and healthy fats. If you want the exact count without guesswork, here’s the short take: a standard 1-ounce handful (about 49 kernels) delivers roughly 34 mg of magnesium, which is about 8% of the FDA Daily Value (420 mg for adults). Scale up by weight or volume and the math holds—100 grams lands near 123 mg, and a full cup (123 g) sits around 150 mg. These numbers come from laboratory-based nutrient databases used by dietitians and food labels, so you can plan snacks and recipes with confidence.

How Much Magnesium Is In Pistachios? By Serving Size

Serving size changes the total, not the density. The figures below use standard database entries for raw pistachio kernels. Roasting and flavoring don’t move magnesium much, so the differences are small in day-to-day eating. Use this table to match your bowl, bag, or recipe scoop.

Serving	Magnesium (mg)	%DV (420 mg)
1 oz (28 g) ~49 kernels	~34	~8%
1/4 cup (~30–32 g)	~36–39	~9%
1/2 cup (~56–60 g)	~68–74	~16–18%
1 cup (~123 g)	~150	~36%
100 g (weighed)	~123	~29%

Magnesium In Pistachios Per Serving (28 G, 1 Oz)

The most common snack size is one ounce. That’s your palm-sized handful of about 49 kernels. This serving brings roughly 34 mg of magnesium. On a label that uses the FDA Daily Value, this is about 8%. If you’re tracking toward the NIH recommended intake (400–420 mg for most adult men, 310–320 mg for most adult women), that one handful moves you a meaningful step along the way.

What Counts As A “Good Source” Of Magnesium?

On U.S. labels, a food that supplies 10–19% of the Daily Value per serving can be called a “good” source. One ounce of pistachios lands just under that band at roughly 8% DV, but it gets there fast once you eat a bit more—about 1.5 ounces clears 12% DV. If you’re building a snack plate, that’s a small pile of pistachios alongside fruit or yogurt.

Where The Numbers Come From

These figures trace back to large U.S. nutrient databases that underpin dietetics tools and many food labels. Entries for raw pistachio kernels list magnesium around 34 mg per 28 g serving and about 123 mg per 100 g. Those values align with analyses used by clinicians and nutrition researchers. For the Daily Value reference used on labels, the FDA sets magnesium at 420 mg for adults and children 4+ years. That’s the benchmark used in the %DV column above.

If you want to double-check the label math or look up other nutrients in pistachios, you can view the FDA’s guide to Daily Values and the NIH’s plain-English fact sheet on magnesium basics. Both open in a new tab.

how much magnesium is in pistachios? In Real-Life Portions

Snack bowls and recipes rarely match a tidy ounce. Here’s a quick way to translate everyday amounts into magnesium without a scale:

Handfuls And Scoops

Loose handful: usually close to 1 oz → about 34 mg magnesium.

Two loose handfuls: roughly 2 oz → about 68 mg.

Quarter-cup scoop: often 30–32 g → about 36–39 mg.

Half-cup scoop: often 56–60 g → about 68–74 mg.

Recipe Swaps

If a salad or pasta calls for 1/3 cup pistachios, count on about 40–50 mg of magnesium in that portion. A pesto with 1/2 cup for two servings will put you around 35 mg per plate from the nuts alone. Toasting for flavor doesn’t move the number much.

Magnesium Gains Beyond The Number

Pistachios bring more than magnesium. A 1-ounce serving also supplies around 6 g of plant protein, roughly 3 g of fiber, and a mix of mono- and polyunsaturated fats. That trio helps with satiety, steady energy, and recipe flexibility. The same handful brings B-vitamins and minerals like phosphorus and potassium. If you’re trying to meet daily magnesium through food first, nuts and seeds are reliable anchors, and pistachios fit well in that rotation.

How Pistachios Compare With Other Nuts And Seeds

Pistachios aren’t the top magnesium source in the nut aisle—that prize goes to pumpkin seeds by a wide margin—but they hold their own and deliver a balanced nutrient profile. The table below shows common snack servings for quick comparisons.

Food (1 oz / 28 g)	Magnesium (mg)	%DV (420 mg)
Pistachios	~34	~8%
Almonds	~76–80	~18–19%
Cashews	~72–83	~17–20%
Pumpkin Seeds (Hulled)	~150–156	~36–37%
Peanuts (Dry-Roasted)	~49	~12%

How To Hit Your Target Intake With Pistachios

The NIH ranges place most adults between ~310 and 420 mg per day. Build a day that gets you there with real food, then use supplements only when a clinician suggests them. One way to plan:

Snack Plan Ideas

Option A: 1.5 oz pistachios mid-afternoon (~50 mg), leafy-green side at dinner, and whole grains at lunch. That often clears the daily mark when you add meals.

Option B: 1 oz pistachios (~34 mg) with yogurt, plus a small pack of pumpkin seeds at another time (~150 mg). Round out with beans and greens.

Option C: 2 oz pistachios across the day (~68 mg) and a bean-based dinner. Easy to sustain, easy to track.

Label Reading: Convert %DV Back To Milligrams

Some pistachio packs list %DV only. To convert, multiply the %DV by 420 mg. A label showing 8% magnesium means about 34 mg per serving. If a brand lists 10% DV, that’s about 42 mg. Small swings happen due to kernel size and moisture, but the ballpark stays tight.

Roasted Vs. Raw: Does It Change Magnesium?

Roasting shifts water and may nudge weight-based numbers, yet the mineral content per kernel holds steady. Salted varieties don’t change magnesium either; they just raise sodium. If you’re watching blood pressure, choose unsalted or lightly salted and build flavor with herbs, chili, or citrus zest.

Allergies, Tolerances, And Portions

Tree nut allergies require strict avoidance. For everyone else, portions are the bigger lever. Nuts are energy-dense, so match serving size to your goals. A kitchen scale removes the guesswork when you need precision for tracking or recipe yields. For casual snacking, pre-portion an ounce into small containers so the magnesium and calories are both predictable.

Cooking Ideas That Keep Magnesium On The Plate

Simple Adds

Fold chopped pistachios into oatmeal, stir them into couscous with herbs, or sprinkle over roasted carrots. The crunch holds, the color pops, and you add a clean hit of magnesium without extra prep.

Sauces And Coatings

Pulse pistachios with garlic and olive oil for a bright pesto. Or crush into a coarse crumb and press onto fish or tofu before baking. Both approaches carry the mineral content straight to the plate.

Frequently Asked Questions

Do Salted Pistachios Change The Magnesium Number?

No. Salt raises sodium, not magnesium. The mineral content in the nut stays about the same. Choose unsalted or lightly salted if you’re watching blood pressure.

Rinse lightly and pat dry before toasting if you want flavor control while trimming surface salt.

Are Pistachios A Better Magnesium Pick Than Almonds?

Per ounce, almonds usually list more magnesium (about 76–80 mg) than pistachios. Pistachios still bring a solid amount with extra perks like vitamin B6 and lutein/zeaxanthin.

If magnesium is your main target, blend both. A small pack of pumpkin seeds lifts the average quickly.

Does Soaking Or Roasting Lower Magnesium?

Soaking changes texture and may reduce some phytates, but minerals like magnesium remain fairly stable. Roasting shifts moisture and aroma with minimal effect on magnesium per kernel.

Mind the salt in seasoned blends. If you cook at home, toast dry and add spices after.

How Do I Convert A Label’s %DV Into Milligrams?

Multiply the %DV by 420 mg. A bag that lists 8% DV equals about 34 mg per serving. Ten percent DV is about 42 mg.

This trick works across foods, not just nuts. It’s handy when a package hides the milligrams.

Should I Use A Magnesium Supplement If I Eat Pistachios Daily?

Food first. Most people can reach daily needs with a mix of nuts, seeds, beans, greens, and whole grains. If a clinician suggested a supplement, bring a food log to that visit.

Set a baseline with your diet, then add a supplement only if a lab result or symptom pattern calls for it.

Wrapping It Up – How Much Magnesium Is In Pistachios?

Per ounce, pistachios deliver about 34 mg of magnesium—reliable, steady, and easy to track. Move up by weight or volume and the count scales cleanly: 100 g near 123 mg, a cup around 150 mg. If you like the taste and crunch, pistachios are an easy way to stack magnesium with protein, fiber, and heart-smart fats. Pair them with pumpkin seeds, almonds, beans, and greens and you’ll hit your daily target without chasing pills or complicated meal plans.
