Origin and history

The algae Chlorella ( Chlorella vulgaris ) are green, single-celled organisms whose name is derived from the Greek word chlōros, meaning green, and the Latin word ella, meaning small. The small green algae can be found in fresh water and is mainly produced in Japan, Germany and Taiwan for the production of nutritional supplements and medicine. The main consumer, Japan, uses it mainly as a dietary supplement or protein-containing food additive.  

Chlorella is ideal as a vegan protein source because the dried mass of the algae contains a whopping 42-58% protein in addition to important nutrients such as vitamin B12, iron and omega-3 fatty acids. Vitamin B12 is particularly important because our body needs it in a variety of metabolic reactions. Microalgae such as chlorella are also a source of a variety of minerals such as magnesium and zinc, important vitamins such as vitamins C and E, and essential fatty acids. Chlorella is also rich in antioxidants, chlorophyll and other vital substances, making it a popular addition to a balanced diet.  

Studies have shown that this algae has numerous potential health benefits. In some animal studies, immunomodulatory and anti-cancer properties have been observed with chlorella supplementation. Several human studies have reported that chlorella can reduce oxidative stress and inflammation, as well as improve fat levels and blood sugar levels. Mind you, this was not observed in all studies. However, the fat-lowering effect on LDL cholesterol is expected when taken between 0-1500 mg per day. The anti-oxidant properties of chlorella suggest, based on one study, that it also has liver-protecting properties. Some studies also suggest a blood pressure-lowering effect.  



Chlorella is considered an environmentally friendly source of protein. Their high growth rate and the ability to grow them in controlled environments make them a sustainable alternative to traditional protein sources.  

Possible side effects  

Although chlorella is generally considered safe, some people may experience allergic reactions or gastrointestinal distress
