Blue Green Algae and Wheatgrass Juice – Are They Really Worth Buying?

Superfoods have become a big trend lately, but is there scientific backing to the nutrient contents of these foods?

The reason some foods are termed superfoods is because their nutrient content exceeds in comparison to other foods. Let’s take a look at two popular superfoods and weigh out their benefits and drawbacks.

This is Part 1 of a series we will be publishing. In upcoming blog posts, we will evaluate maca powder and hemp seeds.

Blue Green Algae - most commonly known for its help with weight loss and cancer, has grown popularity over recent years.

Blue green algae are microscopic plants that grow mostly in brackish ponds and lakes all over the world. They can vary considerably in shape, color and size.

The most common type of blue green algae used for human consumption is spirulina. Spirulina has been proven to have a superior nutritional content in comparison to other foods. Spirulina is 65%-71% complete protein; in comparison beef is only 22% protein.[i]

Little scientific research has been conducted on blue green algae using human subjects, but animal and laboratory studies have shown the plant can be beneficial in treating several different conditions.

Memorial Sloan-Kettering Cancer Center says that blue green algae are used to both prevent and treat cancer. Again, although no human studies have been done, studies done on animals suggest that blue green algae can help to protect healthy tissue from the damaging effects of cancer drugs, radiation and chemotherapy.[ii]

According to Medline Plus studies, spirulina has been shown to reduce sugar levels for people with diabetes and lower cholesterol levels. 

Many recommend blue green algae to aid with weight loss. It seems to act as an appetite suppressant and supports your body in weight management. At this time there aren’t scientific studies to help prove this, only anecdotal evidence (individual success stories).

Studies on animals have shown results with cancer prevention and treatment, lowering sugar levels, reducing inflammation and lowering cholesterol levels. That´s the good news. But there have also been studies done on blue green algae’s negative side effects.

Blue green algae supplements could be contaminated with toxins called mycotoxins as well as harmful bacteria. A study published in May 2000 by Environmental Health Perspectives found that 85 of 87 samples of blue green algae supplements tested contained mycocystins, which are toxic to the liver.[iii]

So when choosing supplements make sure you are choosing a company you trust.

In addition, according to The University of Maryland Medical Center, people with autoimmune diseases, such as rheumatoid arthritis or multiple sclerosis, should beware of taking blue green algae products because they stimulate the immune system, potentially worsening these conditions.[iv]

Wheatgrass- known for its support with boosting the immune system, purifying the blood, improving digestion and fighting chronic illness.

Wheatgrass is a young grass that is part of the wheat family. Though many connect wheat grass to the wheat grain which contains gluten, wheat grass is actually considered to be gluten free since it isn’t sprouted.

Wheat grass is usually pressed or blended in to a juice and served as a 2 ounce shot accompanied by an orange slice. It is also used in supplement form.

The active ingredients in wheat grass are vitamins A, B, C and E, calcium, magnesium, potassium, iron, natural enzymes and chlorophyll. Wheat grass is said to be 70% chlorophyll.

Many say that wheatgrass has miraculous benefits. According to the American Cancer Society, the plant was used in folk medicine to help treat chronic skin problems, cystitis, constipation and gout.[v]

Wheat grass has also been linked with helping cancer patients. Nutrition and Cancer published a study in 2007 which found that breast cancer patients had lowered blood toxicity with regular wheat grass juice administration. [vi]

Columbia University's Health Internet service states that wheatgrass helps to neutralize body odors. In addition, the high chlorophyll levels can help reduce bad breath and dental decay. Dentists sometimes use wheatgrass juice to treat patients with mouth infections.[vii]

Many people have individual success stories with this superfood; unfortunately there have also been negative accounts with it as well.

Since wheatgrass is grown in moist conditions it can lock in mold which after ingested can lead to sickness. In additio,n wheatgrass can breed bacteria which can cause headaches and gastrointestinal issues. To avoid this, make sure to wash the wheatgrass carefully before juicing.

Even though wheat grass itself does not contain gluten, there is potential for cross contamination in the growing process, leaving it unsafe at times for people who have celiac disease or an allergy or intolerance to wheat.

Wheatgrass has also been said to cause nausea for some people. According to Harley Matsil, president of wheatgrass grower Perfect Foods Inc., wheatgrass juice doesn't mix well with other foods. Wheatgrass should be ingested on an empty stomach, plus you should also wait at least an hour to eat after drinking/taking a wheatgrass supplement.[viii]

There have been amazingly positive results and some negative results with these superfoods. With more research done in the near future we can assess the power of these superfoods and how to best incorporate them without any negative accounts.

Until then make sure that you trust the supplement company that you are purchasing from and that you do your research on how much to ingest.

  1. To stop mold, do a final wash in food grade hydrogen peroxide bath. It will kill all mold and bacteria.

  3. Hi..just wanted to point out a mistake in the above article…
    Wheatgrass IS sprouted…the seeds are soaked and then sprouted…. and then placed on soil… the grass itself contains NO gluten.

  4. Thank you for this informative article. My body energy does not resonate well with spirulina, and I hesitate to (and don't) eat it for that very reason.  Same thing with wheat grass juice. I grow my own wheat grass and am so careful about mold and cleanliness – however it does often make me feel nauseous within less than a minute of drinking the juice, and my intuition tells me that my body is reacting that way for a reason. If it was good for me, why would I feel nauseous? The information in this article is helping me to further trust my intuition, despite all the good news in the media about these superfoods!

  7. Kaia,
    Yes wheatgrass is sprouted, thank you for that.
    In addition, like it states in the article wheatgrass has no gluten but there is a possibility for cross contamination and people with severe celiac disease may get an immediate reaction from the tiniest bit of gluten and need to be hospitalized. So it is important to mention that.

  8. Thanks for the article. I heard that spirilina and chlorella are toxic because of heavy metal contamination. Is that true for all or only some brands?
