Chlorella, a blue-green algae, is one of the most nutritionally dense green foods on the planet. While it is debatable, many experts think chlorella offers just about every nutrient required by the human body, including vitamins, minerals, amino acids, essential fatty acids, nucleic acids, chlorophyll and a full spectrum of phytochemicals. A chlorella supplement is an easy way to pump up the nutritional value of your diet. Many people prefer a broken cell wall chlorella supplement like what we offer in our Swanson GreenFoods Formulas line. However, Swanson Kyoto Brand offers a few options that combine chlorella with complementary nutrients based on ancient Japanese knowledge of how nature impacts health.
