The best supplements with spirulina: Comparison and Rankings for 2025

Of all the available dietary supplements with spirulina, BrainMax Pure Spirulina BIO in tablet form performed the best. Its biggest advantage is its extremely low price per daily dose, as one pack contains 1000 tablets. Of course, the pure composition is free of unnecessary additives and the resulting price/quality ratio is therefore absolutely perfect.

Benefits:

• Easy and practical dosing
• Very low price
• Pure formula without unnecessary additives
• One pack lasts a really long time

About the manufacturer:
BrainMax is a Czech brand of dietary supplements, which, in addition to pure sports supplements, focuses onThe company focuses mainly on products that support brain function, concentration, productivity and so on. BrainMax products are characterized by a very high quality and well-thought-out composition, thanks to which they maintain a very good reputation among customers. In the repertoire of this manufacturer you will find classic supplements such as whey protein or pre-workout pre-workouts, but also various vitamins or health foods. We have shared our experience with the BrainMax brand with you, for example, in our review of BrainMax 2.1 Neurohacker or in our ranking of the best CBD oils.

Ingredients and recommended dosage:

• The product contains only pure spirulina in organic quality

In terms of composition, we really have nothing to evaluate in this case. In the package you will find only pure spirulina, which is of course the best possible option. The manufacturer states the recommended daily dose as 1-2 tablets per day. In this case, one package contains an incredible 500 (or even 1000) doses, which is really very unusual among dietary supplements. However, it should be noted that the mentioned tablets are quite small, and thus the daily dose in such a case will not be very large. Most competitors list a much larger amount as the recommended dose, which which is why the price of this product is so much better than all the others. Personally, I would recommend to increase the dosage a bit.

Final assessment:
Spirulina in the form of tablets from the BrainMax brand takes away a really excellent rating from us, as we found basically no flaws on it. In terms of composition, there is nothing to fault it, and in terms of price it also performs very well. Even if you decide to increase the dosage a bit, the resulting price per dose will come out cheaper than competing products.

The MedPharma brand also decided to bet on spirulina in tablet form. MedPharma BIO Spirulina takes away from our comparison a very sympathetic ranking and a clearly positive rating. Again, we were particularly impressed by the combination of low price and high quality. As for the negatives, we must mention the need to swallow a relatively large number of tablets every day.

Pros:

• Completely pure composition without any additives
• Low price per daily dose
• The package contains up to 900 tablets
• Organic quality

Disadvantages:

• The recommended daily dose is a total of 15 tablets

About the Manufacturer:
The Czech brand MedPharma is one of the pioneers in the field of dietary supplements in our country. It has been on the market since 2000. The company manufactures and sells products supporting human health at a very affordable price, which is one of the reasons why it has managed to maintain a relevant position on the market for such a long time. A specific feature of the MedPharma brand is that you can very often come across its products in pharmacies. In addition, you will also find them very often in our trials and tribulations. Examples are the ranking of the best probiotics or the comparison of the best antioxidants.

Ingredients and recommended dosage:

• The product contains only pure spirulina in organic quality

Looking at the ingredients, it is probably not surprising that the product contains only pure spirulina and nothing else. The absence of additives is definitely a big plus and the same applies to the BIO label. What we have to criticize a bit, however, is the recommended dosage. The manufacturer states that one daily dose is 5 tablets three times a day. This means 15 tablets, which is frankly quite a lot. Since the tablets are small, this is obviously not a disaster, but we would still expectif the manufacturer simply made the tablets larger for the convenience of the customer.

Final assessment:
MedPharma BIO Spirulina offers excellent value for money, as it is a completely pure product without any additives, for which you pay essentially minimal price. We consider the already mentioned dosage to be a disadvantage, but that's not a bad thing. One extra pack lasts for two whole months, which is really decent. Ultimately, we can highly recommend spirulina from MedPharma.

Next on our list is spirulina from the GreenFood brand. Among its biggest advantages are its high quality, pure composition and relatively low price. It is a product in the form of capsules, which brings with it very convenient use and easy dosage.

Advantages:

• Low price
• High quality composition without added substances
• Easy dosing
• Hassle-free use

Disadvantages:

• One pack lasts for a fairly short time compared to competitors

About the Manufacturer:
GreenFood is another Czech company that has been in the sports nutrition market for over 25 years. The company's biggest priority is to use quality organic ingredients, so you won't find any preservatives, added sugars, inappropriate dyes and so on in their products. We've shared our experiences with the GreenFood brand, for example, in theof the best sleep-enhancing supplementsor in a comparison of the best l-carnitine supplements.

Ingredients and recommended dosage:

• The product contains only pure spirulina

Again, we are dealing with pure spirulina without any additives. The capsules are made from plant material, so they are also suitable for vegans. The manufacturer recommends a dosage of 2 capsules per day, which is no problem. This makes dosing very easy and there is no need to swallow too many capsules (as in the case of MedPharma, for example). The only possible disadvantage we see is that one pack lasts a person for about 45 days. That's not a short amount of time, of course, but compared to some competing productsproducts, which can last up to half a year, it is a minor drawback.

Final assessment:
GreenFood Spirulina has surprised us very pleasantly and takes away an excellent rating from us. We have not found any major negatives here, all our comments only concern small details. Price-wise, the product comes out very well, although it is true that the previous products came out a bit cheaper per dose. Still, the price/quality ratio is absolutely excellent.

Spirulina in the form of powder from the BrainMax brand appealed to us not only for its very high quality but also for its price. Although it is a bit more expensive than previous products, in comparison compared to other powdered products, it is by far the cheapest. This makes it a great option for anyone who wants to add spirulina to their smoothies or breakfast cereals.

Benefits:

• Very good price
• Organic quality
• Wide range of uses
• One packet lasts almost two months

Disadvantages:

• Powder form may not suit everyone

Ingredients and recommended dosage:

• The product contains only pure spirulina in organic quality

It is no surprise that the BrainMax brand has brought to the market a very high quality spirulina without any additives and with the BIO label to boot. The form of the powder allows the customer to adjust the dosage completely according to himself. The manufacturer recommends taking 1 to 2 teaspoons per day, which corresponds to about 5-10 grams. Depending on the dosage, one packet can last you about 25 (in the case of taking two teaspoons) to 50 (taking one teaspoon) days. Of course, the uses are unlimited, so you can add spirulina to virtually any meal. However, because of the bitter taste, I do not recommend taking it alone.

Final assessment:
BrainMax Pure Spirulina is a high quality powder without any additives, thanks to which you can enrich any of your meals with a variety ofA good dose of protein, vitamins and minerals by simply adding a teaspoon or two. But along with this advantage comes a disadvantage. You always have to add spirulina to your food, which simply may not suit everyone. So if you prefer to take it quickly and easily, capsules or tablets may be more suitable for you. In terms of price, this product comes out to about a third of the price of other powdered products, which is a really huge price difference.

Spirulina from the Revix range of products, which is backed by the MaxxWin brand, also has a very good rating from us. Its spirulina comes in capsule form, which means easy use and easy dosing for customers. Revix Spirulina contains no additives and is packaged in a transparent vegetable capsule.

Benefits:

• Convenient price
• Easy and convenient dosing
• Also suitable for vegans
• Additive-free

Disadvantages:

• Small packaging that doesn't last very long

About the manufacturer:
Although it's not obvious from the name, Revix is not actually a brand name, but just a line of dietary supplements produced by the MaxxWin brand. This Czech manufacturer of sports supplements has been on the market since 2011 and is characterized by itsThe company is especially famous for the fact that it manufactures all of its products in the Czech Republic. Revix is a line of products focused on health, beauty and quality of life. In addition to high quality spirulina, it includes omega 3 fatty acids, barley, various oatmeal, chlorella, etc. You may have already come across the MaxxWin brand in our comparison of the best B vitamins or in our ranking of the best dietary supplements with chlorella.

Ingredients and recommended dosage:

• The product contains only pure spirulina

Only pure spirulina is found in the transparent vegetable capsule, in which there are no added additives either. The recommended daily dose, according to the manufacturer, is a total of 4 capsules. This means in practice that one pack will last you for 22 days, which frankly speaking is really not much. Buying a new pack every three weeks isn't exactly ideal, especially since competing manufacturers offer spirulina in much larger packs that last for an incomparably longer period of time. On the other hand, it's fair to say that one pack is very cheap as a result.

Final assessment:
If you are looking for quality spirulina at a reasonable price, Revix will definitely not disappoint you. In terms of composition, there is really nothing to fault here and the price/quality ratio is still very good. Not counting the aforementioned small packaging, there is basically nothing to criticize here. Ultimately, therefore, Revix Spirulina earns an excellent rating from us.

Nutrisslim Spirulina Powder BIO is another suitable alternative for anyone looking for quality spirulina in the form of powder that can be added to your favourite breakfast porridge, for example. There is nothing in the ingredients except pure spirulina and the overall quality of the product is also proven by the BIO label.

Benefits:

• High-quality ingredients without added substances
• Universal use
• Excellent source of minerals, vitamins and other nutrients

Disadvantages:

• Higher price

About the Manufacturer:
Nutrisslim is a brand hailing from Slovenia that focuses on the production and sale of superfoods. The company prides itself on the high quality of its products, which it achieves primarily by choosing only ingredients from small and honest growers. It also avoids the use of unnecessary and harmful additives. As a result, its products are labelled BIO and RAW and have long been among the most reliable products on the market. You might have come across the Nutrisslim brand in a comparison of the best collagens or in a ranking of the best supplements with chlorella, for example.

Ingredients and recommended dosage:

• The product contains only pure spirulina in organic quality

It is probably not necessary to point out again that Nutrisslim Spirulina Powder BIO does not contain any additives and that it is only pure spirulina of the highest quality. As for the dosage, the manufacturer recommends taking about 3 g per day at first and gradually increasing this dose up to 5-10 g per day. If you average these values and work out that one dose is about 5 g, one pack will last you about 20 days, which is not much. Again, though, you can add spirulina to any meal or smoothie, which is a pretty significant benefit for many people.

Final assessment:
Nutrisslim Spirulina Powder BIO is a high quality product that allows you to reap the health benefits of spirulina to the maximum. Just add one or two teaspoons to your favourite smoothie, protein or even breakfast porridge. However, it should be noted that this product already belongs to the group of more expensive products and one daily dose will cost you significantly more than previous products.

Those of you who prefer supplements in tablet form should also pay their attention to Algae Spirulina Organic from Ekolife Natura. Although this is one of the most expensive products in the ranking, it boasts premium quality and the BIO label. Similarly to MedPharma spirulina, one daily dose according to the manufacturer's instructions is 12 tablets, which is a lot.

Benefits:

• Absolute purity of the product
• BIO label
• Excellent source of important nutrients

Disadvantages:

• Complicated dosage

About the Manufacturer:
Ekolife Natura is a company originating in Slovenia, whose main activity is the sale of liposomal vitamins and similar products. Its repertoire includes a wide range of superfoods and premium natural products. You could meet them, for example, in our ranking of the best collagens or in our comparison of the best K vitamins.

Ingredients and recommended dosage:

• The product contains only pure spirulina in organic quality

As mentioned in the introduction, the manufacturer lists a total of 12 tablets divided into 3 doses of 4 tablets as the recommended daily dose. This can be quite a problem for many people, as swallowing a whole day of tablets is simply not a great thing. In addition, this way the entire pack is used up quite quickly and in 20 a person may be shopping again. On the other hand, it should be added that with this set dosage, you really take in enough spirulina during the day and thus maximize its positive health effects.

Final evaluation:
You have to pay for high quality, this is not news. However, in the case of spirulina from Ekolife Natura, you will pay a lot more. In addition, one pack does not even last for three whole weeks, which is really not enough. It is therefore quite questionable to what extent buying this product is worthwhile for someone who prefers the best possible price-quality ratio in the first place. However, if you don't mind paying a little extra for dietary supplements, this product may be an interesting choice for you.

Detox Supermix from Nutrisslim is a little different from the rest of our ranking. It is not pure spirulina, but a combination of several superfoods offering various health benefits. The presence of the other substances is of course reflected in the price, so it is one of the more expensive products. However, it will definitely be of interest to those of you who would like to add a little bit more to your diet.but don't want to buy them all separately.

Benefits:

• Comprehensive formula containing a total of 5 superfoods
• Organic quality
• Contains no additives

Disadvantages:

• High price

Ingredients and recommended dosage (values for 5 g of product):

• 2.25 g of organic young wheat
• 1 g organic young barley
• 0.75 g organic spirulina
• 0.5 g of organic chlorella
• 0,5 g organic lucuma

At first glance, it is already obvious that Nutrisslim Detox Supermix contains less spirulina compared to other products. This is of course understandable considering that it contains 4 other substances in addition to it. However, we have to appreciate their choice, as it is a really interesting combination of high qualitysubstances offering a wide range of health benefits. Wheat grass is particularly rich in fibre and minerals, barley grassBarley grass and chlorella are valuable sources of chlorophyll and lucuma acts as a natural sweetener with a very low glycaemic index.

Final assessment:
If you are looking for a quality and comprehensive product containing more than just spirulina, Nutrisslim Detox Supermix is for you. It has a really high quality formula without any additives, with all its ingredients complementing each other perfectly. However, as mentioned in the introduction, the price for one daily dose is quite high, which also needs to be taken into account when buying it.

Finally, we must not forget Spirulina Raw Powder from the Belgian brand Purasana. It appealed to us mainly because of its high quality and transparent origin. We consider the high price to be a disadvantage, which is really quite high compared to products from the first ranks of the ranking.

Pros:

• Transparent composition and origin of spirulina
• High quality product without unnecessary additives
• Excellent source of important nutrients

Disadvantages:

• High price

About the Manufacturer:
Although the Belgian brand Purasana was founded in 2010, its roots go back much further. In fact, the company's founder, Raf De Jonckheere, opened his first natural food store back in 1977. The company prides itself on premium quality and only uses 100% sustainable ingredients to produce its products. Due to the high quality standards of its products, the Purasana brand has earned many certifications and trademarks. You may have already come across its products in our comparison of the best chlorella supplements.

Ingredients and recommended dosage:

• The product contains only pure spirulina

The specificity of this product is the fact that the manufacturer also mentions the country where its spirulina comes from - specifically, Mongolia and China. The daily dose is 10 g of powder, which means that one packet will last you for just 20 days. Of course, the high daily dose also contributes to the final price, which is, to be honest, quite high. In terms of composition, however, we really have nothing to complain about and must evaluate very positively.

Final assessment:
If you are looking for quality spirulina at a good price, this product is definitely not the right choice for you. One daily dose is really expensive and although the manufacturer may argue the high quality of their product, the amount ofThe price/quality ratio is definitely not as good as the products that topped our comparison. Purasana Spirulina Raw Powder is indeed one of the best quality products on the market, you just have to pay more for it.
