The short answer
The richest dietary sources of magnesium for PCOS include pumpkin seeds (one ounce provides ~156 mg), dark leafy greens like spinach, legumes such as black beans and lentils, whole grains including quinoa and oats, and dark chocolate (70%+ cacao). Eating a variety of these daily helps meet the recommended intake of 310–320 mg for adult women.
Top magnesium-rich foods and amounts
Pumpkin seeds: 156 mg per oz. Spinach (cooked): 157 mg per cup. Black beans: 120 mg per cup cooked. Quinoa: 118 mg per cup cooked. Almonds: 80 mg per oz. Dark chocolate (70–85% cacao): 64 mg per oz. Including two or three of these in each day covers a significant portion of your daily need through food alone.
Practical meal ideas
Add pumpkin seeds to oatmeal or salads. Stir spinach into soups, stews, or scrambled eggs. Use black beans or lentils as a base for grain bowls. Choose oat-based snacks and quinoa as a side grain. A personalised PCOS meal plan can help you integrate magnesium-rich foods systematically alongside other PCOS-supportive nutrients.
Quick follow-up questions
Do I need to take magnesium supplements if I eat these foods?
Not necessarily. If your diet regularly includes the foods listed, you may meet your magnesium needs through food alone. Supplements may be considered if you have confirmed deficiency or absorption issues—discuss with your healthcare provider.
