According to the Centers for Disease Control and Prevention (CDC), harmful algal blooms (HABs) can produce toxins that make people and animals sick, and these are most often caused by cyanobacteria, which are not true algae. This distinction is critical because while many green algae species are benign, it is the bacteria known as "blue-green algae" that poses the primary threat, and it can be difficult to tell them apart visually.

Green algae have existed for millions of years and are known as nutrient-dense superfoods. The most popular dietary supplements derived from these powerful microorganisms are Chlorella and Spirulina, each offering unique nutritional profiles and health benefits.

Over 20 species exist within the *Chlorella* genus, but *Chlorella vulgaris* is the most widely researched and consumed. The common name for *Chlorella vulgaris* is simply **chlorella**, a single-celled, green freshwater microalgae known for its potent health benefits. Found thriving in freshwater ponds and lakes across the globe, it has earned its reputation as a 'superfood' due to its high concentration of protein, vitamins, minerals, and antioxidants.

Chlorella, a single-celled green alga, has existed on Earth for over 2 billion years, predating most other plant forms. This microscopic organism, often touted as a nutritional powerhouse, is classified within the domain of eukaryotes, sharing a distant lineage with terrestrial plants.

With over 7,000 diverse species, green algae represent a massive and ubiquitous group of photosynthetic organisms found across numerous aquatic and terrestrial environments. The question of what do green algae contain within their cells reveals key insights into plant evolution and offers valuable information regarding their nutritional and industrial potential.

Recent studies reveal that green algae do contain iodine, however, the amounts are much smaller than in brown algae. This difference has implications for those using marine sources to get iodine, as concentrations vary widely across species.

With over 12,000 species, seaweed is a common term for thousands of marine plants and algae, which are broadly grouped into three main categories based on their pigmentation: brown, red, and green algae. These diverse organisms provide essential functions in marine ecosystems, from kelp forests that shelter marine life to oxygen production that supports the planet.

For thousands of years, some forms of algae have been a staple food source in coastal regions worldwide, demonstrating their historical significance in human diets. The answer to "can you eat green algae?" is yes, but only certain commercially prepared and specifically identified species are safe for consumption, while wild variants can be highly toxic.

Most edible seaweeds, a type of algae, are marine-based, while most freshwater algae are considered toxic. This is a crucial distinction for anyone asking: are all green algae edible? The simple and definitive answer is that many green algae are not safe for human consumption, and improper identification can lead to severe health risks.

Some microalgae species, including cyanobacteria often referred to as algae, can contain up to 70% protein by dry weight, making them a highly concentrated protein source. This exceptional nutritional profile has increased interest in understanding what edible green algae rich in protein can safely and effectively boost human health.
