Magnesium in Seeds: Which Ones Have the Most and Easy Ways to Eat Them
October 3, 2026
Magnesium is a mineral that your body uses for hundreds of processes, including muscle and nerve function, making energy and keeping bones strong. Many people eat less than the recommended amount, and seeds are one of the most convenient sources.
How much magnesium do adults need?
Recommended daily amounts for adults are roughly 310 to 320 milligrams for women and 400 to 420 milligrams for men, with slightly different numbers in different countries. Needs change with age and pregnancy, so check the guideline for your country if you want precise figures.
Which seeds are highest?
Pumpkin seeds are the champion. An ounce (28 grams) of hulled pumpkin seeds provides about 150 milligrams, around a third or more of daily needs. Hemp hearts are strong too, with about 140 to 210 milligrams in three tablespoons depending on the brand. Chia seeds give about 95 milligrams in two tablespoons. Sunflower kernels offer around 90 milligrams per ounce, sesame seeds about 30 to 40 milligrams per tablespoon, and watermelon seed kernels also have plenty. Quinoa contributes about 120 milligrams per cooked cup.
Easy daily ideas
Sprinkle two tablespoons of pumpkin seeds on porridge or salad. Stir three tablespoons of hemp hearts into yogurt. Make a smoothie with a spoonful of chia and some ground sunflower seeds. Spread tahini on toast. Cook quinoa instead of white rice a few times a week. Pair seeds with other magnesium-rich foods, such as leafy greens, beans, whole grains and nuts, and you will get close to your target without trouble.
Can you absorb it?
Seeds contain phytic acid, which can reduce mineral absorption a little. Soaking, sprouting, roasting or grinding may help somewhat, but the effect is modest, and magnesium in seeds is still considered a useful source. A varied diet is more important than any single trick.
Food first
Getting nutrients from food is generally gentler than from high-dose supplements, which can cause diarrhea and other side effects. If you think your intake is low, a dietitian can help you look at your whole diet before you reach for pills.
Who should check first?
People with kidney disease should talk to their doctor before eating large amounts of magnesium-rich foods or taking supplements, because the kidneys control magnesium levels. Some medicines, including certain antibiotics, bisphosphonates and diuretics, interact with magnesium, so ask a pharmacist about timing. If you have heart rhythm problems or take blood pressure medicine, mention your seed intake to your doctor. Seed allergies are possible, and pregnant or breastfeeding women should check with their healthcare provider.
Mixing a few different seeds in a jar is an easy way to cover more nutrients across the week.
