5 Benefits of Chlorella, a nutritious microalgae

What is chlorella?

Chlorella belongs to a group of green microalgae and is one of the oldest forms of life on Earth, with roots stretching back more than two billion years.

It is rich in chlorophyll, which gives it its distinctive green color. Microalgae such as chlorella multiply rapidly by cell division and can be grown in controlled environments, such as large ponds, where they are harvested and dried before being ground down to powder or used to produce supplements.

This alga has an exceptionally hard cell wall, which means that it must be treated in order to be taken up effectively by the human body.

By breaking down the cell wall of chlorella, its nutrients are released, making them bioavailable. According to Journal of Nutrition Chlorella has been studied for its nutritional density and potential benefits for human health, making it an interesting component in modern dietary supplements.

Nutritional content of chlorella

Chlorella is exceptionally nutritious and contains a wide range of vitamins, minerals and other bioactive compounds essential for optimal health. Among the most prominent nutrients that chlorella contains are:

1. Proteins: Up to 60% of chlorella consists of protein, which is comparable to many animal protein sources. The uniqueness of chlorella is that it contains all the essential amino acids that humans need, making it a complete source of protein. This is especially important for vegetarians and vegans, as plant-based protein sources rarely offer a complete amino acid profile.
   ‍
2. Vitamins: Chlorella is an excellent source of several important vitamins, including the B vitamins (especially B12), vitamins C, E and K. According to a study published in Nutrition Research and Practice Chlorella is one of the few known vegetable sources of vitamin B12, a nutrient that is otherwise primarily found in animal products. This makes chlorella a valuable supplement for those who follow a plant-based diet.

3. Minerals: Among the many minerals that chlorella contains, iron, magnesium, calcium and zinc are of particular importance. Iron, in particular, plays a crucial role in blood formation, and chlorella has been shown to be able to increase the body's iron storage according to a study in Journal of Medicinal Food. Magnesium is another important mineral that supports the nervous system and muscle relaxation.

4. Omega-3 fatty acids: Chlorella contains small amounts of omega-3 fatty acids, especially alpha-linolenic acid (ALA). These fatty acids are essential for cardiovascular health, brain function, and inflammation reduction.

5. Chlorophyll: Chlorella is one of the most chlorophyll-rich plants on Earth. Chlorophyll has potential antioxidant and detoxifying properties and has been investigated for its ability to bind to and eliminate harmful toxins from the body.

Here are five scientifically proven reasons why chlorella can have beneficial effects on your health:

1. Supports the immune system

Research shows that chlorella can strengthen the body's defenses against infections and diseases. One study found that men who took chlorella for four weeks had an increased production of antibodies, which is important for a strong immune system. Another study showed that chlorella increased the activity of so-called “natural killer cells,” which are crucial in the fight against cancer and infections.

2. Helps balance cholesterol levels

Several studies suggest that chlorella may help lower cholesterol levels. This may be due to the algae's rich content of nutrients such as vitamin B3, carotenoids, fiber, and antioxidants, all of which play an important role in heart health and cholesterol balance.

3. Supports weight loss programs

Animal studies show that chlorella can affect fat metabolism and blood sugar regulation, which can be useful for weight loss. A study published in Journal of Medicinal Food showed that chlorella supplementation reduced body fat, lowered total cholesterol and blood sugar levels over a 16-week period.

4th. May help regulate blood pressure

Chlorella is rich in nutrients such as potassium and arginine, which are known to lower blood pressure. One study found that daily intake of chlorella helped people with high blood pressure lower their levels. Another study found that it reduced the stiffness of the arteries, which is an important factor in high blood pressure.

5. Binds to heavy metals

Chlorella is often marketed for its detoxifying properties. Research in animals suggests that the alga can effectively bind to heavy metals and other harmful substances, helping the body eliminate them. This can be particularly beneficial for people exposed to environmental toxins, although these cases are uncommon in practice.
