The group of green teas was the best source of phenolic compounds (110.73 mg/100 mL) and magnesium (1885 µg/100 mL) and was also characterised by the highest antioxidant activity (59.02%).
NUTRITION IN A CUP
One serving of matcha green tea (½ tsp or 1 gr) contains 306mg of protein, 272mg total amino acids, and 50mg of lipids, amongst other nutrients. It also has minerals such as potassium (27mg), magnesium (2.3 mg) calcium (4.2mg), zinc (.
However, all substances with caffeine do deplete magnesium. You may not want to quit drinking green and matcha teas, for example, or organic coffee (especially if you take it without sugar). If you have a tea or coffee habit, simply replace your lost magnesium daily.
The minerals with the greater amount in green tea leaves are potassium, calcium, phosphorus, and magnesium. In a lesser amount we have manganese, zinc, copper and iron.
But caffeine causes the kidneys to release extra magnesium regardless of body status. If you drink caffeinated beverages such as coffee, tea and soda regularly, your risk for magnesium deficiency is increased.

A 2021 study in Molecules concluded that the antioxidant activity of tea is related to the presence of magnesium and potassium. Of the teas studied, green tea was shown to have the highest concentration of both phenolic compounds and magnesium, and it also presented the most antioxidant activity.
Magnesium deficiency is diagnosed via a blood test and sometimes a urine test. Your doctor may order the blood test if you have symptoms such as weakness, irritability, abnormal heart rhythm, nausea and/or diarrhoea, or if you have abnormal calcium or potassium levels.
Phytates in the diet bind to magnesium and impair its absorption. However the quantities present in normal diet do not affect magnesium absorption. Other dietary factors that are thought to affect magnesium absorption are oxalate, phosphate, proteins, potassium and zinc.
A variety of drugs including antibiotics, chemotherapeutic agents, diuretics and proton pump inhibitors can cause magnesium loss and hypomagnesemia (see Table 3).
Common causes of low magnesium include: Alcohol use. Burns that affect a large area of the body. Chronic diarrhea.
Objectives. Magnesium (Mg), and green tea and rhodiola extract supplementation have, in isolation, been shown to improve subjective stress perception and mood responses to acute stress.
Dried Coriander provides the most magnesium with 694mg (174% DV) per 100 gram serving, or 14mg (3% DV) per tablespoon. It is followed by Chives (160% DV), Spearmint (151% DV), Dill (112% DV), Sage (107% DV), Basil (106% DV), and Savory (95% DV).
Spinach. Many leafy greens contain magnesium, and spinach tops the list at 78 milligrams per 1/2 cup serving of cooked leaves.
Green Tea Improves Immune System
It has an abundance of antioxidants and nutrients that have positive effects on the body. They are improved brain function, fat loss, a lower risk of cancer and several other impressive benefits. It also helps you lose weight, de-stress the body and mind.
Best for overall health: green tea
When it comes to tea, green tea gets the gold. “Green tea is the champ when it comes to offering health benefits,” says Czerwony. “It's the Swiss Army knife of teas. It covers a lot of territory.”
Magnesium glycinate is one of the most absorbable forms of magnesium and has fewer GI side effects than other forms. If you are taking magnesium to address constipation and gut issues, the citrate form will be a better fit.
Magnesium is widely distributed in plant and animal foods and in beverages. Green leafy vegetables, such as spinach, legumes, nuts, seeds, and whole grains, are good sources [1,3]. In general, foods containing dietary fiber provide magnesium. Magnesium is also added to some breakfast cereals and other fortified foods.
Bananas may be best known for being rich in heart-healthy and bone-strengthening potassium, but a medium-size banana also provides 32 mg of magnesium, in addition to 10.3 mg of vitamin C (a good source) and 3 g (a good source) of fiber, according to the USDA.
