Lüttge Organic Spirulina Algae

We are the ones with the algae! As one of the few manufacturers in Germany, we grow the organic spirulina ourselves instead of transporting it from the other side of the world. We are also responsible for the further processing and marketing. This means we can guarantee you products of the best raw food quality and the greatest possible transparency in all production steps.

How exactly are microalgae cultivated here? What do they need to grow? And how are they harvested and processed? Here you can find out everything about the cultivation, harvesting and processing of spirulina on our algae farm. 

Our algae farm

Our algae farm is located in Großenkneten near Oldenburg, surrounded by fields, meadows and forest. This is where we grow and harvest the blue-green algae and where we develop new products.

Our laboratory, where the pre-cultures of organic spirulina are grown, is also located on site. A team of scientists researches the microalgae and its diverse applications there.

Cultivation of organic spirulina

First, the microalgae are grown in small quantities in the laboratory until they can multiply in the large water tanks in the greenhouse. To grow, algae only need carbon dioxide from the air, sunlight, a few nutrients and water.

We only fill our tanks, which are under glass, with German drinking water – one reason for the high quality of our algae products.

After a while, the algae have multiplied so much that the tank is full of fresh algae and we can harvest them.

Harvesting organic spirulina

Since organic spirulina multiplies rapidly under good conditions, we harvest it daily from around April to October. During our many years of working with the microalgae, we have developed a special harvesting process that allows us to harvest a solid algae paste. In winter, our algae are in a deep sleep because there is not enough light and warmth for the algae.

Gentle processing: Good things take time.

After harvesting, our organic spirulina is gently dried at low temperatures. We give it the time it needs to do this, as spray drying is out of the question for our natural product.

After the algae has dried, it is either broken into crumbs or processed into powder. With our specially developed ball mill, it is possible to gently grind the crumbs into a fine powder.  

The low temperatures during drying and the gentle processing in the mill give our organic spirulina its light taste. Our quality, taste and smell of the algae are unique and speak for themselves. Be sure to try it!

The result: Freshly harvested, gently dried organic spirulina algae in excellent raw food quality. With lots of good stuff, but no frills.

Our tip

Find out more in specialist literature, from alternative practitioners, doctors or nutritionists. There is also a lot of information on the internet about the ingredients of spirulina algae. For example, iron and vitamin K are already well known, but often not the focus of our diet. Spirulina also contains chlorophyll, which is super interesting. It is important to look for good sources.

A smoothie with spirulina in the morning helps me absorb my nutrients. I just can't eat breakfast in the morning, but this way I feel fit.

Ten years ago, my alternative practitioner recommended spirulina to me because of its high iron content, but it didn't taste good at all. Now I'm glad I tried Lüttge spirulina again. There's a world of difference in taste. I don't need iron tablets anymore.

I'm a huge fan of the spirulina crumbs! I put them on everything. Salad, yogurt, scrambled eggs... I think they're great.
