How is Organic Spirulina Grown?

Now that you understand the efficacy of spirulina, you must know how the manufacturers grow it to ensure its quality and nutrient retention stats. The manufacturers follow a specific procedure for setting up the environment for the growth of spirulina.

Here is a brief about the steps that they adapt to grow organic spirulina before it’s sent to be converted into powder form:

1. Preparation

The manufacturers use a big-size aquarium with sufficient space to grow spirulina in quantity. Next, they purchase spirulina culture to add to the aquarium. Spirulina culture is nothing but a mix of nutrients and some other components which are responsible for boosting the growth of microalgae.

2. Setting Up The Growing Medium

The next step is to prepare the medium where the spirulina algae will grow. Water, baking soda, and sea salt are added to the medium and stirred until everything dissolves.

Following that, the spirulina culture is mixed with good mineral composition within the aquarium. Now, potassium, phosphorus, magnesium, and iron are added as food sources for spirulina.

In the next step, fresh & unwashed spirulina will go into the container. And one has to keep stirring the aquarium water multiple times a day. It’s because spirulina algae can’t grow in stagnant water.

In 3 to 5 days, the algae will start multiplying within the container. Over time, the water is checked for freshness, and the nutrient content value is maintained at optimal levels. Maintaining the water levels is also equally important, as evaporation occurs in an open-top aquarium.

3. Harvesting & Processing

After a few days, the spirulina is observed to have changed colors from light to dark appeal. Hence, this determines if the algae are ready for harvesting or not.

When the algae are ready for harvest, they’re collected from the aquarium, and the water is drained. After the filtration, the left-out moisture is removed by pressing the algae under heavily weighted objects.

Algae is then sent to the processing machines to reduce them into the shape of noodle-like stripes. These stripes will then be set for drying under natural sunlight for the next few hours.

After the algae is properly dried, it’s crushed and converted into powder. This powder form then undergoes examination and tests for its purity and healthiness before it can be packaged for end-consumers.

Hence, this is how spirulina is grown organically by the manufacturers. You can conclude that the best safe source of spirulina for these manufacturers is to either grow it themselves or obtain it from GMP-approved facilities.

The success of this supplement has even impressed the scientists at NASA. Currently, spirulina is undergoing tests on whether it can replicate the same nutritions for human bodies when grown in space.

Upon the success of such review tests, NASA has decided that spirulina will be grown in space and it’ll meet the food & nutrient requirements of the astronauts.

Is it Important to Know Your Spirulina’s Source?

Yes, it’s important to determine the source of spirulina because that tells a lot about the quality of the product you’re consuming. Products sourced from specific countries or labs have lead in it, which isn’t appropriate for pregnant women.

You should always go for products that are USDA certified and sourced from verified facilities for ensuring genuineness. Edible spirulina algae should be grown in a controlled environment to prevent harmful water impurities from hampering the algae.

Does Organic Spirulina Contain Heavy Metals?

No, it’s not always the case! If the organic spirulina is sourced from alkaline lakes, there’s a high chance that it might have heavy metals and other impurities. But, when spirulina is grown in a proper facility and a man-made environment, the chances of it being infused with heavy metals are eradicated.
