Gut microbiome,
the core of your health

Your intestines are responsible for digesting and absorbing nutrients, but through the gut microbiome, they also play a major role in your immune system, skin, energy levels, and even your mood. Yet, research shows that almost 1 in 4 Dutch people suffer from digestive complaints (source). At plnktn, we help tackle this problem with one of nature's most nutritious sources, full of unique micronutrients: algae.

The natural boost
for your gut

Plankton is a mix of 4 micro and macroalgae to supplement your diet and support your intestinal system¹. Every day, you're one step ahead by adding algae to your diet. Full of important nutrients: fiber, antioxidants, minerals, and vitamins.

Plktn does what it promises. I've been using the capsules for a few years now. My bowels are completely happy again, after a life of constant constipation. I also have more energy. Even my husband is going to use it now.
Quick and clear responses to my
questions, and recently received a nice cap and water bottle. Excellent company.

I am very happy with the product; I chose the powder form because I don't like taking pills, and I'm pleasantly surprised by the taste. From day 1, it has worked very well for my intestines; for the rest, I'll wait and see, but I'm positive. Nice packaging and a storage jar included, and easy to contact with questions.

Composed of the most nutritious algae

Carefully selected and sustainably grown in Europe, rich in essential and gut-friendly nutrients.

Chlorella

Grown in Oldenzaal (the Netherlands) in closed fermentation tanks for the highest possible quality. Rich in B vitamins, including B12.

Wakame

Grown in Brittany, France, in a protected marine ecosystem, wakame is a natural source of iodine and packed with fiber and minerals.

Spirulina

Grown in Catalonia (Spain) and dried at a low temperature to preserve nutritional value, spirulina contains calcium, iron, and the antioxidant phycocyanin.

Lithothamnion

Collected along the coast of Iceland, exclusively from naturally occurring seaweed, Lithothamnion is a mineral-rich source of calcium and magnesium.

  • Chlorella

  • Lithothamnion

    Collected along the coast of Iceland, exclusively from naturally occurring seaweed, Lithothamnion is a mineral-rich source of calcium and magnesium.

  • Fiber & Prebiotics

    Spirulina, chlorella, and wakame naturally contain various dietary fibers: polysaccharides that serve as a food source for the gut microbiome. Microalgae such as spirulina and chlorella primarily provide soluble and highly fermentable fibers, which nourish your gut bacteria. Seaweed like wakame contains, in addition to fermentable fibers, insoluble and less fermentable fibers, which contribute to normal bowel movements and intestinal motility. Combining microalgae and seaweed creates a broader variety of fiber types, which better suits a diverse and resilient gut microbiome.
  • Antioxidants & Phytonutrients

    Algae are among the richest sources of marine bioactive compounds. Chlorella contains chlorophyll. Spirulina contains phycocyanin. Wakame provides fucoxanthine. These compounds are among the most researched marine phytonutrients and are globally recognized for their role in cellular protection and repair processes.
  • Vitamins & Minerals

    Plankton combines multiple natural sources of micronutrients. Chlorella provides B vitamins, including B12. Spirulina contains iron, calcium, and trace elements. Lithothamnion is rich in ocean minerals such as magnesium and calcium. These marine nutrients come from clean ecosystems and are naturally incorporated into the algae's nutritional profile.

Collapsible content

Is plankton for me?

If you're looking for a natural way to support your daily health, Plankton is for you!

While everyone is unique, our bodies require many of the same essential nutrients. Plankton provides an easy, daily supplement for your overall health. It is packed with minerals, vitamins, antioxidants, fiber, and protein, all of which contribute to a healthy lifestyle.

What is the difference between plankton & other food products?

Plankton stands out due to its unparalleled nutritional density. Simply put, this means: many nutrients from a small amount. With just 2 grams of this pure product per day, you can already make a difference.

Additionally, it is the natural origin of these four micro- and macroalgae that makes plankton unique. Where other supplements are often synthetic and contain excessively high dosages, plankton is 100% natural and plant-based, without synthetic additives.

The perfect, naturally balanced addition to a healthy and varied diet.

Should I take plankton every day?

Of course, nothing is a must! We do recommend a maintenance dose of 2 grams (4 capsules) per day as a supplement to a varied diet and a healthy lifestyle.

What is the capsule made of?

The capsules are made of HPMC (hypromellose). This is a polysaccharide (carbohydrate) extracted from plants and wood. This is, incidentally, the most common way to make plant-based/vegan capsules. HPMC is known for being easily digestible.

Is plankton free of allergens?

As far as we know, our algae are free of allergens.

However, the product may contain traces of fish, shellfish, and crustaceans. This is because the algae mix contains two types of seaweed.

Is plankton suitable for children and/or during pregnancy/breastfeeding?

Plankton is safe for children. However, for children up to 10 years old, we recommend 2 capsules per day. This is partly due to the high iodine content.

For pregnant women and/or during breastfeeding, we recommend discussing this with your doctor (or general practitioner) first, as there is insufficient research on the use of algae during these periods.

Why are algae the food of the future?

In addition to the fact that algae are extremely rich in important nutrients, they also offer real advantages in terms of sustainability. Compared to traditional food, algae do not require agricultural land and are extremely economical with water. In addition, algae are one of the fastest growing organisms and they convert CO2 into oxygen and valuable biomass. They do this more efficiently than any other plant on earth.

For these reasons, algae are often mentioned as an important source of nutrition for the future. At plnktn, we are taking the lead in this. We believe that algae will live up to their promise and be part of a healthy and varied diet. plnktn 's 1000+ 5-star reviews are living proof for us.

Why choose plnktn?

If you believe that algae can contribute to your health, we promise you the following:

1. We always aim for the highest quality
2. We carefully and regularly analyze quality and safety
3. We do this together with local nurseries and renowned algae scientists
4. We continuously strive for improvement

The result? A pure and clean product with the highest possible nutritional value we can provide.

Is plankton suitable for people with thyroid disease?

The recommended dose of Plankton (2 grams, 4 capsules) contains approximately 60% of the recommended daily allowance (RDA) of iodine. This may be a concern for people with thyroid disorders.

To limit iodine intake, it may be advisable to skip plankton or reduce the dosage to 1 gram per day (2 capsules). We always recommend consulting your doctor first to make the best choice for your health.
