USDA nutrient data cited in nutrition analyses ranks dried basil, oregano and dill among the most magnesium-dense foods by weight.

Common dried herbs used in everyday cooking are drawing attention as concentrated dietary sources of magnesium, according to nutrient data from the U.S. Department of Agriculture cited in multiple nutrition reports.
The data places dried basil, oregano and dill among the most magnesium-rich foods by weight, putting some familiar seasonings in the same nutritional conversation as nuts and seeds. Analysts said the high mineral concentration is largely the result of drying, which removes water and leaves behind a denser concentration of plant nutrients.
Dried basil contains about 400 milligrams of magnesium per 100 grams, according to USDA data cited in nutritional analyses. Dried oregano provides about 270 milligrams per 100 grams, while dried dill contains about 250 milligrams per 100 grams. Other dried herbs with notable magnesium levels include parsley, sage and thyme.
Magnesium is considered an essential mineral because of its role in more than 300 biochemical processes in the body. The National Institutes of Health says magnesium is involved in muscle contraction, nerve transmission, bone formation, protein synthesis, blood glucose control and blood pressure regulation. The mineral is also needed for proper heart, kidney and muscle function.
Despite its importance, officials said many people do not meet recommended magnesium intake levels. The recommended dietary allowance for adults ranges from 310 to 420 milligrams per day, depending on age and gender, according to the Office of Dietary Supplements.
Low magnesium intake has been associated in observational research with health concerns including muscle cramps, fatigue and cardiovascular issues. A meta-analysis of observational studies found that increasing magnesium intake by 100 milligrams per day was associated with a 22% lower risk of heart failure, a 7% lower risk of stroke and a 19% lower risk of diabetes, researchers reported.
Dietitians say dried herbs can be an easy way to add small amounts of magnesium to meals without increasing sodium or calories. Because herbs are concentrated, even modest amounts used in soups, sauces, marinades, dressings and rubs can contribute measurable mineral intake.
“Sprinkling dried herbs on meals is a simple way to increase mineral consumption,” said a clinical nutritionist quoted in nutrition guides.
Researchers caution, however, that herbs should be viewed as part of a broader nutrient-rich diet rather than a replacement for magnesium supplements when a deficiency is diagnosed. People with known deficiencies may still need supplements under medical supervision.
“Herbs provide a natural source of magnesium along with other beneficial compounds,” said a university researcher cited in a 2025 review of nutrient-dense foods.
Herbs also contain additional plant compounds beyond minerals. Some studies have associated flavonoids and polyphenols with reduced inflammation and support for bone health. Food composition analyses indicate that dill, for example, contains flavonoids and essential vitamins in addition to magnesium.
A study on herbal medicaments published in Food Chemistry found that magnesium from herbal preparations showed high bioavailability, with extraction efficiency reaching up to 100% for some minerals. Researchers said the finding suggests magnesium in dried herbs may be readily usable by the body.
Officials at the Office of Dietary Supplements recommend obtaining magnesium from foods when possible, noting that plant-based sources can be well absorbed as part of a varied diet.
Nutrition experts said dried herbs are not typically consumed in 100-gram quantities, meaning they should not be treated as a primary magnesium source on their own. Still, their density makes them a useful addition to meals, especially when combined with other magnesium-rich foods such as seeds, nuts, legumes and leafy greens.
For consumers looking to improve mineral intake through food, the data suggests that small changes in seasoning habits may help. Adding basil, oregano, dill, parsley, sage or thyme to routine meals can increase nutrient diversity while also improving flavor without relying on added salt.
