the testers advise against the consumption of all three tested AFA preparations.And most of the other products - capsules and tablets with the freshwater algae Chlorella or Spirulina - are "poorly suited" to fulfilling the expectations aroused on the packaging.All three types of algae contain a lot of protein.However, the preparations tested only cover a fraction of human needs: in the highest recommended dose, they provide 1.1 to 5.4 grams of protein per day – but a man weighing 70 kilos needs around 56 grams. for example in athletes, pregnant women or those suffering from stress, is not apparent.Although some of the tested products advertised with such statements on the packaging.Vitamins, minerals and other vital substances are only sporadically advertised there - and then usually to be consumed with caution.Some products contain quite a lot of iron, especially Ivarsson's Hawaiian Spirulina.However, it has not been conclusively clarified whether the additional intake increases the risk of disease.The nutritional value table on greenvalley Spirulina and GSE Afa-Alge also causes problems, according to which both supply the body with a lot of vitamin B 12.Because the vitamin is found in afa and spirulina mainly in a form that humans cannot use.And for the chlorophyll advertised on some products, nobody needs to reach for algae.It is found in all green parts of plants, including green vegetables, and even gives them their color.Other claims about freshwater algae, as can often be found on the Internet, are unlikely to stand up to strict scrutiny.This applies in particular to health effects.For example, none of the algae products available in Germany are licensed as medicinal products.Instead, most are legally considered dietary supplements, some even food.Consequence: You do not have to provide proof of effectiveness.It is worth not spending your money on algae preparations, but on a varied diet with lots of fruit, vegetables, whole grain products and potatoes.Lean meat provides iron, fatty sea fish provides valuable fatty acids, and dairy products provide calcium.In this way, an abundance of vital substances reaches the body – even without algae to swallow.More tips for a healthy diet.08/05/2020 -

I've been taking seaweed for years, I'm fine.- I have many acquaintances who all take algae and nothing has ever happened.- Test's article is sponsored by the Pharmalobby.- Politicians want to prevent algae from taking hold.- The WHO is a mafia It goes like this all the time.I would therefore like to expressly thank Test.These comments underscore the importance of independent authors using traceable testing methods to prepare information that can then be used to draw more informed conclusions.So there is unequivocal evidence of carcinogenic microcystins and the comment mob pours out a shitstorm about those who measured and published these extremely disturbing test results.This is basically a bankruptcy declaration.Too bad that the two German manufacturers Algomed and Lüttge were not tested.Comment deleted by admin.Reason: surreptitious advertisingToxic microcystins in algae preparations?Why is there no criminal complaint with the public prosecutor's office?If you have a little background knowledge, you can quickly see the chain of arguments in this article.The old story, they should quickly appear trustworthy to a stupid reader.Sometimes statements are left unsupported, no precise details are given as to which studies are involved, rather alternative nutrition is ridiculed and hacked off as a marketing strategy, so people are constantly talking about it, and one paragraph distracts from the topic with information to inspire confidence, who cares about the chlorophyll in this case?it doesn't matter nutritionally, but it sounds chemical and educated.And anyone who uses the WHO as the only legitimate "supporter" of this article, then everyone knows what it's about again, I'd rather eat algae than sick, genetically modified animals you killed.Here is my guaranteed confirmation of the effectiveness / detoxification effect of the chlorella algae tablets: I was pregnant in 2004 when we had the old spray plaster washed off + new plaster applied to the house.Hot summer, inevitable that I inhaled the dust from it and absorbed it over the skin while cleaning + gardening.Residues from the scaffolding blew into the rooms for many days when they were aired.That one chrome poisoning etc.could have, I didn't know.But I felt nauseous, the salivary glands in my neck kept swelling up, but I couldn't eat anything that was even remotely alkaline.Not even tap water, otherwise my favorite!I could only swallow food/drinks containing vinegar.Tortured me for 3 weeks.The doctor then recommended chlorella.I was very skeptical, but after the 3rd serving of 3 tablets, relief set in and the next day the symptoms finally disappeared, and didn't come back when the glass was empty.(The latecomer was born healthy)Yes, I would like to subscribe to the Stiftung Warentest newsletter.Information on the newsletters and data protectionRead more on the topic© Stiftung Warentest.All rights reserved.
