Jump Ahead to the Best Chlorella Products

What is Chlorella?

Faced with the looming threat of uncontrolled proliferation of the human population during the 1940s and 50s, scientists began researching alternative food sources to combat the anticipated food shortages. Chlorella quickly grabbed the spotlight as a promising candidate for solving the world hunger crisis.

Chlorella is a type of green aquatic algae native to the freshwaters of the far east. Depending on the exact species as well as cultivation & processing methods, dried chlorella can contain upwards of 50% protein, 20% carbohydrates, 20% fat, and a significant amount of vitamins and minerals.

Due to practical concerns regarding the costs of large-scale cultivation, chlorella never really claimed its place as a mainstream food source. However, its status as a superfood was recognized by the health and wellness community, making it a popular dietary supplement.

Uses & Benefits of Chlorella

Due to the spike of interest in chlorella, many scientific studies were conducted to investigate its nutritional value, as well as its applications in various conditions.

*No currently existing evidence supports the use of chlorella as a standalone treatment or as a substitute for conventional therapy for any of the above indications. Consult your physician before making any changes to your treatment regimen.

How to Take Chlorella

Chlorella can be found in the form of pills or dried powder. Pills are more convenient to consume, while powder may be blended into your morning smoothie/juice or sprinkled on salad and yogurt. The choice is up to personal preference, and both forms should yield similar results.

There is no concrete evidence on the optimal chlorella supplement dosage. Most sources recommend anywhere between 2-8 grams per day. We recommend that you start with a lower dose and work your way up gradually.

Chlorella Side Effects and Precautions

Chlorella intake may produce some undesirable effects including diarrhea, flatulence, nausea, stomach cramping, and skin rash. More serious side effects may include precipitation of asthma attacks.

Since chlorella may contain iodine, people who are allergic to iodine should avoid it.

Chlorella may interfere with the action of blood-thinning drugs such as Coumadin (Warfarin).

Chlorella may cause strengthening of the immune system; this may be problematic in people with autoimmune diseases such as lupus, multiple sclerosis, and rheumatoid arthritis. Chlorella use should be avoided during pregnancy.

What to Look for in a Good Chlorella Supplement

  • Species of chlorella: “Chlorella” is an umbrella term under which multiple species are classified. The best-studied species are chlorella pyrenoidosa and chlorella vulgaris, so look for supplements that contain these species.
  • Broken cell wall: Chlorella has a very tough cell wall that impedes our bodies’ ability to absorb and utilize the nutrients inside. A number of methods are used by manufacturers to break the cell walls, including milling or grinding, chemical breakage, and heating-and-freezing. Milling is often cited as the method that produces the least loss of nutrients.
  • Purity: Many manufacturers lab-test their chlorella to ensure that they are free of contaminants.
