But first, what is phytoplankton?
Phytoplankton are small, photosynthetic organisms that drift in aquatic environments, such as oceans, lakes, and rivers. These organisms are of great importance for the origin of life.
Acting as the foundation of the food chain in numerous marine and freshwater ecosystems, these small, single-celled algae play a vital role. Beyond their impact on the food chain, phytoplankton also contribute significantly to global carbon cycle.
By absorbing carbon dioxide from the atmosphere and releasing oxygen through photosynthesis, they shape the delicate balance of our planet's ecosystems. Scientists estimate that at least 50 percent of the oxygen in our atmosphere has been produced by phytoplankton.

Natural, renewable and sustainable
Through photosynthesis, phytoplankton provide us the oxygen we need to breathe
Every ton of phytoplankton consumes up to 1.8 tons of CO₂
They are autotrophic: they produce their own food using light, water and carbon dioxide
They are safe to eat
They can grow on non-arable land making them the most sustainable source of nutrients
Highly Nutritious
Phytoplankton are the first step in the aquatic food chain, thus the first natural food
They are the most nutrient-rich organism on the planet: high quality complete proteins, all 9 essential amino acids, rich in omega 3, 6, 7, 9
They are a high source of polysaccharides with natural antibacterial properties
They are 100% natural, allergen-free and vegan
