Brown algae - versatile!
Brown algae (also known as kelp), scientifically known as Phaeophyta, are a group of algae that live in water. They are found in various marine environments around the world, especially in cooler regions. Their characteristic name is derived from their brown colour, which is due to the presence of pigments such as fucoxanthin.
In this article, you can find out more about the many uses and everything you need to know about brown algae.
What are brown algae good for and what nutrients do they have?
In addition to their ecological importance, algae are also of interest as an ingredient in the food industry, particularly in some Asian countries. They are used in the production of foods such as seaweed products, soups, salads and sushi. As a natural organic ingredient, algae is an exciting addition to foods and supplements.
We recommend opting for products that are made by trustworthy manufacturers. Before you start taking seaweed extract capsules, it is recommended to speak with a doctor or nutritionist, especially if there are health concerns or specific goals.
Brown seaweed is a rich source of various nutrients, vitamins and bioactive compounds, including [2]:
Iodine: Seaweed is one of the best sources of natural iodine. Iodine is an essential trace element that is needed for healthy thyroid function and the production of thyroid hormones. A lack of iodine can lead to thyroid problems such as goitre or hypothyroidism, but excessive intake of iodine can also be harmful and should be strongly avoided.
Fucoxanthin: This carotenoid pigment has antioxidant properties. It is also being investigated whether fucoxanthin can help with weight loss by increasing metabolism and promoting fat burning.
Fibre: Some types of brown algae are rich in fibre, which can aid digestion and create a feeling of satiety. Fibre contributes to general gastrointestinal health.
Minerals and trace elements: In addition to iodine, it also contains other minerals such as potassium, iron, magnesium and calcium as well as various trace elements that are important for the body.
Polyphenols: Brown algae powder may also contain polyphenol-rich compounds that have an antioxidant and potentially anti-inflammatory effect.
Vitamin A (retinol): The extract contains carotenoids such as beta-carotene, which can be converted into vitamin A by the body. Vitamin A is important for skin health, vision, the immune system and growth.
Vitamin K: Brown seaweed may also contain vitamin K, which is important for blood clotting and bone health.
Can brown seaweed have an effect on the skin?
Brown seaweed can have a variety of beneficial effects on the skin, mainly due to its rich composition of bioactive compounds, minerals, vitamins and antioxidants [1]. Here are some possible applications of this extract:
Moisturisation: Kelp brown seaweed contains natural moisturising factors that can help to hydrate the skin and prevent moisture loss [4]. This can help to keep the skin supple and hydrated.
Antioxidant effect: Kelp brown seaweed contains antioxidants such as vitamin E, vitamin C and carotenoids, which can help to protect against oxidative stress and premature skin ageing caused by free radicals [4].
Anti-inflammatory: Some components of these algae, such as certain polyphenols, may have anti-inflammatory properties [4]. This can help to support the skin against redness and inflammation.
Firming and toning: Due to its nutrient composition, kelp extract can help to support a normal appearance of the skin [7].
Collagen can also have a positive effect on the skin and hair. Here you can find out more about this important protein, which you can also take as a dietary supplement: https://vita-world24.de/en/blog/Collagen-hydrolysate-what-to-look-out-for

What benefits can be achieved by taking algae capsules daily?
Brown algae extract, often available in convenient capsule form, is a highly concentrated source of many valuable ingredients. Brown algae itself is known for its rich composition, including vitamins, minerals and bioactive compounds.
A daily intake of brown algae extract, e.g. in capsules or as brown algae powder, in combination with a healthy lifestyle and diet is recommended to support the thyroid gland in its normal function due to the iodine [2]. However, people with thyroid disorders should avoid supplements containing algae and should generally consult a doctor before taking them.
This type of algae can also help with weight management, as the fibre it contains aids digestion [4]. Fibre is considered to support intestinal health, regulate digestion and contribute to a longer feeling of satiety [6].
How to dose brown algae extract?
Brown algae extract is often offered in capsules, tablets or as a powder that can be dissolved in water or added to smoothies, for example. These dosage forms are practical and easy to dose. The mg information varies greatly from product to product and it is important to pay attention to the difference between μg and mg due to the iodine it contains.
Due to the different compositions, the recommended daily dose varies, but it is important to pay particular attention to the dosage due to the high iodine content: It is recommended to take a maximum of 100 micrograms (not mg) iodine per day via food supplements, including all meals you should not consume more than 500 micrograms (not mg) [3]. The dosage can be adjusted according to individual needs, but it is recommended to consult your doctor before taking it.
As brown algae powder or capsules are taken as a dietary supplement, it is important not to consider it as a substitute for a varied diet, but as a valuable supplement.
What positive properties do algae have?
Firstly, algae can support the metabolism in order to achieve normal function - studies are looking at the effect of fucoxanthin on lipid metabolism [4].
Algae products can also contribute to general health due to their antioxidant properties [4]. Antioxidants can fight free radicals in the body that can damage cells [5]. The polyphenols found in algae can help to reduce oxidative stress and thus protect cells [4].
To summarise, brown algae in capsules or other forms as a dietary supplement is one way to take advantage of the positive properties of this algae. The practical capsules with highly concentrated algae extract make it easy to integrate the ingredients into your daily routine.
