Chlorella, a single-cell, fresh-water green algae, is an excellent source of high-quality protein that is easily digested. Chlorella has many benefits to assist in achieving optimal wellbeing, and should be taken daily. It has been shown to increase the elimination of heavy metals and pesticides from the gastrointestinal tract, muscles, ligaments, connective tissue, and bones. It is helpful with blood sugar regulation, for both hyperglycemic and hypoglycemic episodes. Changes in the expression of genes involved in the insulin signaling pathway were positively affected by chlorella, especially those related to glucose uptake in tissue, providing support for the observation that chlorella lowers blood glucose levels. Studies show that chlorella is useful for the absorption of dietary lipids. It brings about improvements in fat metabolism, making it an effective supplement to lower triglycerides and cholesterol, resulting in improved cardiovascular health. It also has been shown to improve vitamin and mineral absorption, decrease inflammation, increase energy levels, and help to heal and repair human RNA/ DNA.
