Industry - Food & Nutraceuticals


Seaweeds have been consumed for thousands of years and appreciated for their taste and nutrional value.

They draw their incomparable mineral content (iodine, calcium, magnesium, iron, ...) deep from the sea by synthesizing organic elements like proteins, sugar complexes, amino-acids, vitamins, ...

We concentrate all these benefits of seaweed nutrition for your greatest pleasure.


Edible seaweed is mainly hand-collected by our "Goémoniers" (local seaweed harvesters) on the foreshore at low tide. They are then brought to the premises, washed, dried and sieved within 24 hours.

Depending on its composition, each species is different and appreciated for its specific benefits...

We offer a 100% natural range that combines originality and added-value to all your products (seaweed nutraceuticals).

Agar Agar

Agar is produced from the red seaweed Gracilaria verrucosa or from red seaweeds of the genus Gelidium. It is Malaysian in origin and was discovered in the 17th century by the Japanese.

It is produced by careful processing of the natural polysaccharides by an aqueous extraction of the seaweeds, followed by freeze-drying that preserves all its richness.

It is used in many preparations, serving as both a gelling and thickening agent. It is precisely because of its plant, or more strictly algal, origin that Agar is of interest. The gelatine that occurs in commerce is obtained by the prolonged boiling of the collagen found in animal bones and skin.

Whereas Agar is a very pure natural product, with no additives and therefore very good for the health. It also has working properties that are much greater than synthetic products or those of animal origin. Finally its complete lack of taste does not mask the true flavours of the foods in which it is used.

Algalithe®(Lithothamnium calcareum)

Lithothamnium Calcareum is a red seaweed belonging to the family Corallinaceae. Its thallus is shaped like a miniature tree several centimetres long with branches of a few millimetres, so that it resembles a coral. In Brittany it grows on sandy seabeds at a depth of about thirty metres. It grows extremely slowly, giving it time to filter and absorb large quantities of nutrients from the sea, especially calcium and magnesium, which it is able to retain because of its great porousness. It can form reefs several centuries old.


Laminaria digitata (kelp) is a brown seaweed belonging to the order Laminariales. It is one of the largest seaweeds occurring on Brittany coasts.

Its glossy brown thallus can reach 3 to 4 m in length. It has a cylindrical, smooth, flexible stem called a stipe and a thallus divided into laminae. This thallus is fixed by a holdfast to the rocks near or below the low tide level down to a depth of 10 m.. This type of seaweed is considered to be the anatomically most advanced.

One of the specialities of the kelps is their high concentration of extractable alginates, which give them their flexibility allowing them to withstand the pounding of the waves.

Ao Nori

Ao Nori is green seaweeds belonging to the order Ulvales. This seaweed, that is sometimes called Hollow Green Weed in English, includes several commercially exploited similar-looking species. The thallus is tubular and flattened in shape and more or less branched, or sometimes in the form of a simple ribbon of variable width but usually rather constant for a given individual.

These are short-lived seaweeds that appear especially in spring. They occur in all types of habitats, in exposed or sheltered conditions and on rocks or on gravel.

Ascopharm® (Ascophyllum nodosum)

Ascophyllum nodosum is a brown seaweed belonging to the order Fucales. It grows on rocks at about the mid intertidal level in exposed areas, where it replaces Fucus that prefers calmer waters. The brownish-green thalli grow in tufts, each of them composed of strapshaped fronds of different ages all growing from a common holdfast base. These thick flattened straps can reach a length of 1 to 1.5 m and have nodes at intervals along their length with air bladders that serve as floats so that the plant can stand upright in the water. They are irregularly branched with short lateral branches. The age of the seaweed can be deduced from the number of nodes - they can often live for more than fifteen years.


Dulse, Palmaria palmata, is a red seaweed belonging to the order Palmariales. It has a more or less palmate frond shape, from which it derives its name. The reddishbrown blade has a thallus that is dichotomously divided into strips 2 to 3 cm wide and up to 50 cm long. It is attached by a basal disc-shaped holdfast and grows in the intertidal zone on rocky substrates, up to the high water mark where it occurs as an epiphyte growing especially on Laminaria hyperborea.

Fucopharm® (Fucus vesiculosus)

Fucus vesiculosus is a brown alga belonging to the order Fucales. It grows on rocky shores where it is exposed at low tide. Its flattened thallus, a few tens of centimetres long, is dichotomously branched. Either side of the midrib it bears bladders filled with air - hence its name - that serve as floats so that that it stands vertically in the water. During the reproductive season, the thallus stops growing and conceptacles form at the tips, which then release the gametes.

Haricot de mer®

Himanthalia elongata is a brown seaweed of the order Fucales. It is solidly fastened to its substrate by a disc-shaped holdfast with a stalk and grows in the form of two thick ribbons that can reach a length of 2 to 3 metres. It is an annual species that disappears at the end of summer after the two ribbons have completed their reproduction. Growth then starts again in early winter with the formation of new shoots. Flourishing at the low tide limit, Himanthalia elongata is said to be infralittoral.

Sea Lettuce

Ulva lactuca, called Aosa in Japan, is a green seaweed belonging to the order Ulvales. It occurs in the form of thin crinkled leaves sometimes rolled into a spiral, with a maximum length of 30 cm. The very thin blade, consisting of a double layer of cells, is fixed to the substrate by a disc to which it is connected by a very short stipe. Despite its thinness it is surprisingly resistant to tearing because of its high content of elastic fibres. Ulva lactuca occurs in a wide range of habitats, both sheltered and exposed, from the shore to far out at sea. The frond shrinks in winter, then grows again in spring. The green colour also changes with the seasons, changing from very light to dark green.

Chondrus Crispus

Chondrus crispus is a red seaweed belonging to the Rhodophyceae class. Its mucilaginous thallus has a branched lichen-like form 10 to 20 cm high.

Several tufts of different ages sprout from a shared holdfast base. Although this base is permanent, the fronds are annual. They usually branch dichotomously, being cylindrical at the base and flattened at the ends.

When submerged in the water, the red fronds have a bluish reflection. Chondrus crispus grows on rocks at a depth of 6 to 7 metres, which are only exposed at the lowest spring tides.


Porphyra is a red alga belonging to the order Bangiales. Its scientific name simply comes from the word for the colour purple. In terms of structure it has an extremely thin frond, thinner even than sea lettuce since it consists of a single layer of cells. This frond can reach a length of 60 cm. It grows on rocks in exposed wave-beaten coastal areas in the mid intertidal zone. It has a short lifespan, but because is reproduces quickly it can be found almost throughout the year.

Salade de la Mer®

The queen of the Algues Gastronomes®, Salade de la Mer® is an unique product. This recipe is a balanced blend of Dulse, Sea lettuce and Nori.

The design of this concentrated blend on these three seaweeds, each in precise proportions, thereby letting each of them express their flavours and bring out their own respective colours (red, green and black).


Undaria pinnatifida is a large brown seaweed belonging to the order Laminariales. This seaweed attaches to rocks by a hapteron (holdfast). The stipe is flattened with dentate margins that turn into lobe-like projections. The blade is a translucent green colour, triangular and lobed, with a pronounced midrib. It grows in shallow water but can grow to a length of 2 to 3 m. It originated from Japan, and then arrived in the Mediterranean from where it has now spread to Brittany.

Micro seaweeds

Micro seaweeds are cultivated in fresh water ponds under the strict control of biologists and technicians.

Each species has specific properties, essentially depending on its composition: proteins, beta-carotene, chlorophyl, omega 3, ... Thanks to our experience and processing technique, we are able to supplement these compositions naturally.

Their low iodine and lipid contents make them interesting ingredients for specific applications.

The most remarkable species are: Spirulina, Chorella, Odontella, Dunaliella, Haematococcus, ...


Chlorella is a microscopic unicellular alga measuring about 5 μm across. It occurs in warm freshwaters throughout the world. The alga contains an exceptional growth factor that enables it to divide and reproduce very quickly. It forms part of the phytoplankton - the very basis of the aquatic food chain that is the basis for life on Earth.


Spirulina is a blue-green alga now classified in the Cyanobacteria. It is a microscopic unicellular alga with a spiral shape 250 μm long and an intense blue-green colour. It grows wild in tropical and subtropical inland water bodies. Micro-algae such as Spirulina constitute the phytoplankton, which is the basis of the aquatic food chain. They are therefore essential for all life on earth.

Seaweed extracts

We also offer seaweed extracts which can concentrate specific elements and facilitate their use.

The main species are already available according to generic specifications in dry or liquid forms.

Ascophyllum Nodosum Dry Extract

The Ascophyllum Nodosum Dry Extract is a 100% natural product, used for different types of applications.

Fucus Dry Extract

Fucus vesiculosus is a brown algae from the Fucales family. It grows on rocks which are uncovered at low tide. Its flattened thallus, which measures a few dozen centimetres, branches out at random. It has air bladders around its central nervous system, full of air - giving it its name - which enable it to float and maintain a hold in the water. During its reproduction period the thallus stops growing to conceptacles at its end which will release gametes.

Marine Ingredients

We rely on the unmatched experience of the marine habitat to select a wide range of ingredients extracted from seawater, shellfish and fish.

These natural marine ingredients meet the most strict quality criteria for pharmacopoeia and nutraceutical applications.

We are at your disposal to answer every specific request.

Seawater filtered

The sea is a very rich environment, both in terms of quality and diversity, especially when its minerals and trace elements are considered. The proportions of its elements are extremely close to our body's natural requirements and are almost identical to those of blood plasma.

The seawater is pumped off the coast of Brittany, in the Atlantic ocean. It is pumped from a depth of five meters below the surface on rocky bottoms in calm seas. The seawater is first pumped into a decanter at the end of flood tide (rising tide) on an open site in deep water. It is prefiltered to five microns then filtered to 0,2 microns by a sterilizing filter, after which it goes through a UV sterilizer.

Spray-dried seawater

The sea is a very rich environment, both in terms of quality and diversity, especially when its minerals and trace elements are considered. The proportions of its elements are extremely close to our body's natural requirements and are almost identical to those of blood plasma. This is why we offer you this Seawater obtained by evaporation, which keeps it intact and preserves its richness, in readiness to give you back all its benefits.

Origin: Seawater comes from protected sites guaranteeing the very highest purity. It is rich in minerals supplied from the Atlantic Ocean by the mixing of currents and waves, which oxygenate it and make it fresh and full of vitality. Evaporation is a simple process that transforms seawater into a state of fine solid particles, with no heat treatment, so that it conserves all its elements.

Marine Magnesium

Marine Magnesium Oxide is extracted from sea water after desalination and lagunage This aqueous extract is purified and then dried by vacuum evaporation. The product obtained perfectly purified. Magnesium is an essential element for all living organisms and can be supplied by using this product in its very many applications.

Oyster Shell Powder

Biology and Ecology: The Brittany oyster is undoubtedly one of the noblest shellfish in the world. Bathed by the invigorating waters of the Atlantic Ocean, with its rich mineral and plankton resources, it is of the highest possible quality. This quality is found in the oyster's shell. By finely and continuously filtering the seawater that is constantly being replaced in its habitat, the oyster shell can absorb great quantities of minerals. The process keeps intact all these minerals stored in the oyster shell by an appropriate treatment.

Harvesting: Brittany oysters are harvested from sites entirely free of any pollution, where they grow at low population densities so that each oyster can accumulate minerals in its shell in an ideal fashion with very high trace element concentrations.

Atlantic Salt

Our Atlantic Salt, derived from the Atlantic Ocean, oxygenated by the action of currents and waves, is incredibly rich in trace elements that provide the human body with all their benefits. Atlantic Salt is harvested from protected sites guaranteeing the greatest purity. Composed of white crystals, it is obtained by the natural action of the sun, wind and marine currents.

We can provide Atlantic Salt of various degrees of fineness (fine or coarse) for practicality in use in all applications.

Organic Crithmum Maritimum

Biology and Ecology:
Crithmum maritimum is a coastal plant belonging to the family Umbelliferae (now Apiaceae). Its English name is a corruption of the French Herbe Saint Pierre. The yellow flowers are grouped into umbels with oval down-curved bracts. The thick fleshy leaves are alternate and trifoliate with linear leaflets.

It grows to a height of 30 cm above the high water mark, firmly anchored among rocks, pebbles and sand, and especially on cliff ledges where it is exposed to the wind and the salt spray that supply it with minerals. The fleshy leaves are a beautiful shiny bluish-green colour. It is both a medicinal and an aromatic plant that has been known since Antiquity.

Golden Samphire

Biology and Ecology:
The Golden Samphire is a perennial plant with long stems, from the Asteraceous family. At first glance, its leaves can be confused with those of Samphire. From July to September, the plant forms clumps of bright yellow flowers. It releases off a scent reminiscent of "underwood".
