Chlorella tablets

Chlorella is a highly beneficial and nutritional form of green algae. As a supplement, it is praised for its ability to support the immune system, remove toxins from the body, and even improving cholesterol levels. Chlorella must be taken as a supplement due to how our body digests it, and it is available in powder, tablet, or capsule form. It is rich in vitamins like Vitamin B12, iron, protein, antioxidants, fiber, and omega-3 fatty acids. Chlorella has gained a lot of traction in the health and wellness community, but let’s take a closer look to see how this microorganism really works.

How Does Chlorella Work?

This single-celled green alga has many health benefits due to its ability to rid the body of harmful toxins. Animal studies have shown that chlorella is able to bind to heavy metals and other toxins in the body, helping remove them. Algae, in general, have also been shown to weaken the toxicity of some of these heavy metals in the liver, brain, and kidneys. Chlorella also helps lower the number of chemicals sometimes found in food.

Additionally, chlorella has been found to enhance our immune response. Some studies have shown that chlorella has been linked with increased production of antibodies in the body, which directly helps fight harmful invaders that enter the body. Chlorella also contains niacin, antioxidants, and carotenoids, which are especially helpful in lowering cholesterol levels in the body as well as protecting the body from diseases in general. Also, because of chlorella’s strong antioxidant capacity, it is great for fighting inflammation in the body and preventing chronic diseases.


Benefits Of Chlorella

Helps Remove Toxins 

Chlorella is able to bind to harmful heavy metals and toxins that we acquire from our environments and foods and help remove them from our bodies. This helps our immune system function more properly and helps keep our body healthy. Removing toxins from the body also helps promote liver health and removes some of the stress often placed on the liver to help the body naturally detoxify. This detoxification also helps prevent disease and illness.

Boosts Immune System

Chlorella helps improve immune health by removing harmful toxins and chemicals from the body. Chlorella also helps directly boost immune health by weakening the toxicity of some of the harmful chemicals and heavy metals that we might be ingesting. Chlorella has also been shown to directly increase the number of antibodies in the body, which bolsters the strength of our natural immune response as well. Chlorella is also rich in many antioxidants and beneficial vitamins and nutrients like niacin, Vitamin B12, iron, protein, and fiber, which all support a healthy body and immune system. The antioxidants in chlorella also help support healthy aging and fight against preventable disease and inflammation in the body.

May Help Lower Cholesterol Levels

Chlorella contains powerful vitamins and minerals like niacin, fiber, carotenoids, and antioxidants. These beneficial nutrients have been proven to improve and support healthy blood lipid levels in the body, including our cholesterol levels. Antioxidants help prevent the oxidation of LDL cholesterol, which is a known marker and cause of heart disease.
