6. Peanuts
Pop a cup of peanuts in your mouth and you already gained 4.6 grams arginine. You won’t want to do that though with just one sitting because it is rich in fat. You should spread that one cup into small servings within the week. Aside from protein, peanuts are a good source of vitamin B3 and E, niacin and folate. To make a delicious smoothie, combine peanuts and bananas.
7. Spirulina
Spirulina is a variety of blue-green algae that is typically found in the sea. It comes processed as a powder form and is used as an additive to smoothies because of its nutritional content. One cup of powdered spirulina contains 4.6 grams arginine with high amounts of iron, calcium, niacin and potassium. To make smoothie recipes, you need 1 tablespoon spirulina, which has 0.28 grams of arginine.
