By Michael A. Smith, MDseaweed. They’re a very large and diverse group of simple organisms. They can be as small as a single cell or as large as the giant kelps that grow to 65 meters in length in temperate oceans.
Most algae, including chlorella, act like plants by creating energy from sunlight — a process called photosynthesis. But they’re still considered "simple" because their cells and tissues are not organized into the many distinct internal organs.
Naturally growing algae are an important source of food, especially in Asia. They provide many vitamins, including vitamin E,folate and vitamin C, and are also rich in iodine, potassium, iron, magnesium and calcium.
Some species are also a rich source of beta-carotene and B vitamins.1,2
Chlorella - An “Underground” SupplementChlorella was one of the first algae to be cultivated as food and formulated into supplements. Industrial production of chlorella products began in Korea and Japan following the Second World War.
Throughout the 1960s and 1970s, researchers were able to isolate many nutrients from chlorella, including amino acids, protein, minerals, vitamins and antioxidants.
It's been somewhat of an “underground” supplement for nutritional enthusiasts, as it’s taken several decades to gain the attention of mainstream supplement users.
These days, it’s finally growing in popularity as an important immune booster.
Chlorella Improves Immune ParametersResearchers from Yonsei Univeristy in Korea studied chlorella’s immune properties.
They recently completed a short-term study measuring changes in specific immune parameters during chlorella supplementation.3
The researchers recruited 51 healthy Koreans for their 8 week study. All participants were randomized into either a group receiving 5 grams a day of chlorella or a placebo group. The results were quite impressive. Here’s what they found:3
- The activity of Natural Killer Cells, a type of immune cell, significantly increased in the chlorella group.
- Two immune proteins involved in fighting viruses and bacteria, interferon-gamma and interleukin-1 beta, increased significantly in the chlorella group.
This can only be answered through additional research, which we look forward to.
Chlorella Boosts Your Built-in Cancer and Infection Fighting SystemSupporting a robust immune system is really one of the key steps to living a longer life. Your immune system is responsible for fighting and destroying anything that is foreign to your own cells and tissues. That includes not only bacteria and viruses and yeast, but also cancer cells.
As such, consider adding chlorella to your list of immune boosters. Many of us already take vitamins C and D and other immune nutrients, like selenium and bitter herbs.
Adding chlorella to this list may very well be a good idea if strengthening immunity is important to you!
