Iaso® Techui is 100% refined spirulina powder, a nutritious form of alkaline food. It is rich in protein, vitamins, minerals, chlorophyll and other essential nutrients needed daily by the human body. Used by Aztecs centuries ago, spirulina became increasingly popular when used by NASA astronauts in the 1970s as part of their diet. Gram for gram, spirulina may literally be the single most nutritious food on the planet. Its outstanding nutritional profile, high protein, and low calorie count makes it a superfood providing excellent nutrients. Recent scientific research suggests numerous health benefits of this super-food. Spirulina is a natural “algae” (cyanbacteria) powder that is incredibly high in protein and a good source of antioxidants, B-vitamins and other nutrients. It is one of the most potent nutrient sources available. A study conducted at the JC Bose Institute of Life Sciences, Bundelkhand University, Jhansi, published in Current Pharmaceutical Biotechnology in 2005, reported that spirulina improves the activity of white blood cells, stimulates antibodies and increases the population of natural killer cells.
