Algae are among the oldest life forms in the world. The term "algae" refers to the various eukaryotic organisms which thrive in water and naturally carry out photosynthesis. Algae can be found almost anywhere in the world, in both fresh and salt water. They are an integral part of the cuisine of many cultures due to their compelling taste and valuable properties. Other well-known varieties include nori, spirulina and ecklonia abd above all chlorella.

Chlorella Algae

Algae are among the oldest life forms in the world. The unicellular eucaryote, only 5–10μm in size, has a spherical shape and an exceptionally high chlorophyll content. Its particularly strong cell walls contain hemicellulose, which offers the cell stability. Chlorella has an extraordinarily fast reproduction rate, with every cell division taking only 16–20 hours. The chlorella growth factor (CGF) contained in the cell nucleus accounts for this high rate.  CGF is a unique complex of nucleic acids, nutrients, amino acids, peptides and polysaccharides that is responsible for the high resistance and rapid reproduction rate of the microalgae. Chlorella's unique nutrient profile, its high protein content and its valuable secondary phytochemicals make it an interesting superfood.

Sunday Chlorella from Japan with nano-cell walls

In contrast to other strains of Chlorella, Sunday Chlorella from Japan has a particularly fine nano cell wall made of special polysaccharides. This chlorella has an approximately 82% digestion rate and thus the nutrients are optimally bioavailable and retained. Exceptionally High Chlorophyll Content Natural colouring agents such as chlorophyll do not only help in photosynthesis, but are also alkalising and highly potent antioxidants. Sunday Chlorella from Japan has an exceptionally high chlorophyll content due to its ideal cultivation conditions: - Chlorophyll: 3.100mg/100g. Additionally, our Sunday Chlorella from Japan is rich in riboflavin folate and vitamine K1 and is also a good source of iron.  As a result of their growing conditions, freshwater algae such as spirulina and chlorella have an iodine content much lower than that of sea algae.


Recommended Dosage

Take 5-10 tablets (200mg chlorella per tablet) with 200ml water twice daily.

In cases of increased requirements, for example following illness, up to 10,000mg chlorella can be taken per day (corresponds to 50 chlorella tablets). To reach a higher dose, gradually increase the number of tablets consumed each day.

Food Supplement

Do not exceed the recommended dose. Food supplements cannot replace a balanced and varied diet. Keep out of reach of children.
