Blue-Green Algae

About Blue-Green Algae

Many people mistakenly believe that the term “Blue-green algae” refers to one particular type of underwater plant, when in fact it is used to describe several different species of fresh and salt water organisms that are similar in cellular makeup to plants. While blue-green algae is becoming popular in treating a number of different health conditions, it should be noted that, there is still not enough scientific evidence to prove or disprove whether it is an effective ingredient in natural supplements.

Where Does It Come From?

Blue-green algae can be found in fresh and salt water, though these different plant species mainly thrive in tropical or subtropical waters. The natural color of these simple celled plants can also effect the color of the surrounding water, and the different types of algae found in the area will be influenced by temperature, altitude, and how much daily exposure to sunlight there is during the year. Blue-green algae is also grown commercially or a managed natural setting, but there is often a risk of contaminates which can include bacteria and potentially toxic heavy metals. You should only ingest products containing Blue-green algae that has been tested and found to be free from any harmful particles.

What Are Its Possible Health Benefits?

While Blue-green algae is still being tested, it is high in iron, protein, and necessary minerals. While researchers insist that the protein content in the algae is the same as what you would find in milk or meat, it is being studied for its effectiveness at treating various health conditions. Some of the potential uses for the algae include treating viral infections, and reducing various types of inflammation. Other researchers are studying its effects on boosting the immune system.

While researchers are still studying the possible benefits of the algae, many people are already using it to treat a variety of different health problems. Its high levels of protein, iron, and B complex vitamins make it effective at reducing and treating the symptoms of PMS, ADHD, diabetes, and even help improve some cases of depression. When taken as a supplement the algae can also help with weight loss, reduce stress and fatigue, along with relieving feelings of severe anxiety.

What Are The Health Risk Of Blue-Green Algae?

Even though studies are still being conducted on the algae, researchers generally agree that it is safe for the majority of men and women to take as long as it is free from contaminates. You should always check with your health care provider before adding any new supplement to your diet, and this is especially true with the algae. Blue-green algae that contains heavy metals, bacteria, or other harmful particles can cause severe health problems including liver failure. It is also important to note that any potential side effect from the algae that can include nausea, vomiting, shock, thirst, and rapid heart rate will be worse in younger children.

Recommended Dosage and Timing for Blue-Green Algae

There are too many factors to consider to recommend a specific or general dosage. As always this question will be best answered by your health care provider. It is important to remember that younger children will be effected more quickly by any potential side effects than adults, and you always want to follow the recommended dosage instructions listed on the side of the bottle.

Use of Blue-Green Algae in Supplements

This simple cell plant can be used in supplements to help treat a variety of different health conditions, along with helping to boost the levels of vitamin B in your body. The dietary protein found in blue-green algae can also be an effective ingredient in some natural weight loss supplements. While there is still more research to do before scientists know how effective the algae is in the different natural supplements, it is showing promising results.

Blue-Green Algae Interactions

Research is still ongoing, but if you are currently experiencing problems with your immune system, or taking medication for it you will want to avoid taking the supplement.


While research is still ongoing, the results are promising for the health benefits of Blue-green algae. It is an excellent source of vitamins, minerals, and protein, and is showing signs of being able to reduce and treat many different health conditions. With proper advice from a health care provider, you can enjoy the healthy benefits of Blue-green algae.
