Chlorella is a single-celled freshwater alga that is a superfood, which essentially means that they have an inherently high nutritional density. It provides a substantial amount of nutrients while containing very few calories. Chlorella is also known as the Emerald Food due to its excessive content of chlorophyll, a green pigment present in plants for the process of photosynthesis.

The superfood contains a range of nutrients, namely- proteins, omega-3 fatty acids, vitamins, and minerals. The superfood possesses several health benefits if consumed daily.

It is available as a supplement in liquid, powder, or tablet form. People can add Chlorella powder to salad dressings, beverages, and baked goods to boost their everyday nutritional value. While most people are only aware of Chlorella being a good source of proteins, it is also known to have several other health benefits.

Health Benefits of Chlorella

It strengthens the immune system due to the presence of vitamins B12, B6 and iron. It also enhances cellular metabolism and cell regeneration, while controlling body weight and improving the metabolism of lipids. The presence of Chlorella growth factor strengthens the cells and enables detoxification of skin and collagen appendages. Due to Chlorella naturally containing biotin and copper, it ensures strong, shiny hair for those who take its supplements.
In an interesting study administered in 2009 with mice, it was found that Chlorella played a significant role in preventing age-related mental decline. This could be due to Chlorella’s antioxidant effects on the brain. However, it cannot be concluded that the alga would have the same effect on human beings but the results of the study do sound promising in treating dementia.
In another study published in the Journal of Clinical Biochemistry and Nutrition, it was noted that the study population who took Chlorella supplements saw an increase in their peak oxygen intake, indicating that Chlorella might help increase aerobic endurance capacity. This was a small investigation, and it had various limitations. However, it could mean that Chlorella might one day play a role as a supplement for athletes.

Applications of Chlorella

One of the most interesting applications of Chlorella is in cosmetic formulations. The microalgae have sun protection skills due to the presence of chlorophyll-a in its composition, which absorbs sunlight. In addition, Chlorella extract is also used by the skincare industry, since some compounds from the extract have anti-ageing properties, and anti-irritant features. Facial moisturizers made with Chlorella extract promote skin hydration and also aid skin cell renewal.
Skincare formulations, like Dermochlorella, which use Chlorella extract have proven to show firming, restructuring and eye contour effects because it stimulates the synthesis of collagen. In addition, it decreases the morphology of stretch marks and reduces vascular imperfections.
