About Spirulina

Green spirulina powder

Spirulina is a single-celled cyanobacterium, also called algae. This algae exists in bodies of water and is often farmed, especially for its nutritional content. Spirulina contains several natural components, which makes it the perfect natural supplement.

The processed form of this algae is usually packaged as tablets or powders. The consumption of Spirulina has been long approved, and it is encouraged as a part of our daily diet. Spirulina contains several vitamins, minerals, proteins, and antioxidants.

Additionally, Spirulina is more of a plant and lacks animal vestiges: this makes it a great option for vegans and non-vegans.

Spirulina and Your Body

Generally, Spirulina is good for the body and offers a myriad of health benefits. However, some conditions can cause Spirulina to trigger a negative response in your body. One major factor affecting Spirulina’s integrity is the processing industry.

It’s possible to contaminate Spirulina when processing it. These contaminants include bacteria, chemicals, metals, and so on. Some of these contaminants can affect organs in your body, such as the liver and kidney, when ingested.

To avoid complications from the consumption of Spirulina, you must get your product from a certified brand. Ensure you get a USDA-certified brand that doesn’t contain genetically modified organisms.

In addition, some health conditions and medications don’t support the use of Spirulina and can cause complications. Ensure you consult your doctor before using the supplement if you’re already on medication.

Spirulina also has a lot of components that are beneficial to the body. It contains several essential amino acids and can be considered one of the best protein sources.

It contains essential nutrients like vitamins, copper, magnesium, iron, and other micronutrients. These nutrients are vital for building your body, repairing tissue, maintaining hormonal stability, and several other benefits.

Spirulina also contains anti-carcinogenic components like antioxidants and anti-inflammatory factors. It’s great for regulating blood sugar, heart rate, repairing tissue, and several other uses.

Factors to Keep in Mind When Getting Spirulina

The supplement market is swarmed with various brands of Spirulina, and it’s best to go about it with enough information. We want to show you some factors to consider so you can find a supplement that will satisfy you completely.

The Nature of the Formula

When we say the nature of the formula, we’re referring to how organic the product is made. Spirulina is a naturally occurring algae and has a lot of nutrients. The beauty of this algae is that it exists naturally and provides nutrients without any additives.

The more organic the product, the better it will be. Non-organic products are more likely to get contaminated and are riskier than their organic counterparts.

Ensure you check how organic the product is before you make a purchase.

Type of Formula

The type of formula refers to its shape or form. Several forms of Spirulina exist, but the most common are powder, gelatin capsules, and tablets.

Knowing what type of formula you want before shopping is best. The tablet form and capsules give you a more accurate measure of the dosage, but some may find them difficult to ingest. If you don’t have a problem with swallowing, you can go for tablets and capsules.

Also, remember that some of these tablets have a taste that’s not agreeable to some people.

The powder is another common form and is preferred to tablets and capsules. The powder is administered using teaspoons or a set unit of measurement. It’s easier to ingest and can be consumed in many ways.

Ensure you know what form of spirulina works for you: tablets, capsules, powder, or others.


This point is completely optional, and there’s no wrong choice. Most brands today make both the flavored and unflavored versions of their supplement.

The flavored supplements have modified tastes to make them more agreeable for kids or those who don’t enjoy the taste: however, this somewhat reduces the nutritional value. On the other hand, unflavored supplements are purely natural, without additives, and have higher nutritional value.


Any product made for consumption needs to be strictly scrutinized to avoid poisoning. The supplement’s container should contain recognized agencies’ records or symbols of certification. One such agency is the United States Department of Agriculture.

These regulated agencies are responsible for checking the purity of the Spirulina and ensuring it contains no harmful substances. Double-check your brand of choice and make sure it’s certified for consumption.


From the products we’ve discussed, you’ll notice they have some features in common. These features should be listed on the container of the product.

A proper Spirulina supplement should not contain genetically modified organisms. Also, it should be gluten-free, soy-free, and free of any other toxins and components that make it unfit for vegans. All these are usually indicated on the container.


The size of a nutrient supplement tablet goes a long way in influencing your decision. Spirulina supplements are available in different forms and sizes. The size you buy will depend mainly on how you plan to consume the supplement.

Also, the form determines how much supplement is available to you. Some supplements contain 240 tablets, which can last for months of continuous use. You can also buy the supplement as a powder, which you can mix into a delicious smoothie.

It’s best to get a big size if you use the supplement daily—you can get a smaller size for less frequent usage.

Does Spirulina Have a Taste?

Spirulina has a taste, but it varies with the individual. Some people even claim there is no taste.

Spirulina can have a natural taste like river water, neither sweet nor bitter. Some brands can even add flavors, such as mango, banana, and pineapple, to enhance their products’ appeal.

Using Spirulina

There are different ways you can ingest Spirulina. There’s no perfect method—instead, you can try different methods and pick the one that suits you best.

You can swallow the tablets directly using water or any other liquid. Also, you can decide to dissolve the tablet in liquid or crush it into a powder.

The powdered form gives you more options on how to ingest it. You can spread or mix the powder into your food or drink. It’s easier to use Spirulina this way because it’s less obvious and tastes better.

It’s best to use the supplement in the morning as you start your day and also in the afternoon. However, it’s not recommended to use at night because of the energy boost it provides.

Benefits of Spirulina

As a natural product, several health benefits come with Spirulina. It also contains several components that help the overall function of the human body. Here are some of the benefits of Spirulina:
