There are a whopping 18.8 mg of magnesium in a single Brazil nut, meaning that an ounce (about 6 nuts) will net you nearly 113 mg of magnesium — more than a third of the daily recommendation. While Brazil nuts are a great source of magnesium, it’s important to not go overboard. They’re extremely high in selenium, which can be toxic in large amounts. Research shows that just two Brazil nuts a day are all you need to reap their nutritional benefits.

Pine nuts have 71.2 mg of magnesium in a 1-ounce serving. You’ll find them most often in pesto and salads, which is great news because pairing pine nuts with leafy greens (which are also high in magnesium) is a great way to reach your daily magnesium goal.

In every 1-ounce serving of hazelnuts, there are 46.2 mg of magnesium. Consuming hazelnuts regularly has been linked to lower risk for heart disease, type 2 diabetes and high blood pressure. There is even some evidence to suggest that hazelnuts can help reduce your likelihood of developing certain cancers.

With 44.8 mg of magnesium in every ounce, walnuts are rich in vital nutrients and antioxidants. They are great sources of omega 3s – fatty acids that support the brain, heart, immune system and more – as well as vitamin E, which protects the body from damage by free radicals that weaken cells over time.

Macadamia nuts clock in at 36.9 mg of magnesium per ounce. Aside from their high magnesium content, they’ve been shown to reduce high cholesterol, inflammation and oxidative stress, which can support overall health.

Tied with pistachios, pecans also contain 34.3 mg per 1-ounce serving. They’re a remarkable source of healthy fats, and may help protect against heart disease, gallstones, type 2 diabetes and high blood pressure.
