What characteristics should a good spirulina have?
Purity of composition: a good spirulina should be free of artificial fillers, colours and preservatives. A pure composition ensures that the product provides only natural nutrients.
Certification and quality control: Products that are certified and subject to regular quality checks are more reliable. They provide assurance that spirulina meets high production standards.
Origin: Checking where spirulina comes from is important to ensure its quality. Well-established regions, such as Taiwan, are known for their high standards of both environmental and regulatory standards affecting the quality of the algae.
Growing conditions: Good cultivation practices ensure that spirulina has optimal conditions for growth, which directly affects its biochemical composition and nutritional value. The type of water (fresh, salty, mixed) has a significant impact on nutritional value.
Safety: relevant certifications, such as those for Good Manufacturing Practices (GMP), ensure that spirulina is safe and produced to the highest standards.

The Nutridome dietary supplement with spirulina capsules is a product that deserves recognition. It contains 400 mg of seaweed extract in a recommended daily serving of two capsules, making it easy to use and tailor to individual needs. The pack contains 60 capsules, enough for a month's treatment. Testers experienced positive effects, including weight loss-enhancing properties, after just two weeks. With its rich protein and mineral content, Nutridome spirulina is an excellent dietary supplement, offering support not only for weight loss, but also for overall health.
OstroVit Spirulina supplement stands out in the market as a quality product, offering an easily digestible form of spirulina in tablets. Dedicated to those concerned with a healthy diet and looking for a vegan solution, it presents itself as a practical addition to the daily diet of key nutrients. The dosage is high and the capsules, although quite large, are not much of a problem to swallow. The only grumble is the manufacturer's declaration that Ostrovit Spirulina is a vegan product while at the same time including information about the risk of fish, shellfish and eggs in the ingredients.
Swanson Spirulina supplement features a simple formulation and promises effectiveness, offering a natural composition enriched with micronutrients such as iron, magnesium, selenium, and chromium. Each tablet delivers a good amount of spirulina and allows for the flexibility to tailor the dose to individual needs, although the recommended daily intake of up to 3 tablets can be a challenge due to their size. Despite the potential health benefits, however, the product is somewhat questionable in terms of efficacy as it is not produced to European standards and spirulina itself has no stated standardisation.
The Spirulina dietary supplement from Now Foods is popular on the market due to the proven effectiveness of its key ingredient. Each tablet contains spirulina extract, ensuring a rich source of vitamins and minerals. The product is particularly appealing to vegans and vegetarians as it is free of zoonotic additives. The tablets are easy to swallow, which is a big plus, but unfortunately this doesn't change the fact that the recommended dosage is very inconvenient - the manufacturer recommends taking as many as six tablets a day, which is severely inconvenient and makes the pack run out very quickly.
The Myvita Spirulina dietary supplement presents itself in a practical tablet form that is easy to swallow, which is a definite advantage. The product does, however, require it to be taken in quite a large quantity - twice a day, three tablets each, which can be a bit cumbersome. Users may not notice quick or significant effects, either in terms of weight or overall wellbeing. There are plenty of tablets per pack, but having to take as many as 10 per day makes constant supplementation very inconvenient.
