You can add moringa powder to your smoothie or drink it as a tea. The leaf powder was deemed safe in human studies, even in larger doses than normal. The powder has a mild flavor, so it makes for a light moringa tea with a slightly earthy taste.
But you might want to stay clear of seed extract consumption, as they have shown a level of toxicity in immune cells.
Moringa can have laxative effects in large quantities, so a safe dose to introduce it into your food or diet and avoid digestive problems is ½ to 1 teaspoon per day.
