Zhou Nutrition is a very well-known company that offers a wide variety of high-quality supplements.
The company sources its spirulina from a remote farm in Southern California. It soaks up clean air and mineral-rich water, so you can be sure it’s pure and toxin-free. What’s more, the powder is lab-tested to ensure purity. It’s also 100% vegan-friendly.
The company claims that just two servings of its spirulina powder contain as many antioxidants as seven servings of fruits and veggies. In other words, it’s great for boosting your energy levels and making you feel healthy.
However, what makes it the best spirulina powder is that it’s non-GMO, kosher, halal, vegan, and free from allergens. It’s suitable for practically anyone who wants to boost their health in a natural way.
Moreover, the powder tastes good, so you won’t have to “hide it” in shakes and smoothies. It’s also cultivated following the nature-friendly processes.
If you’re always on the go and don’t have the time to mix the powder with your meals, you might want to try Organifi Green Juice. It’s also an excellent way to take spirulina if you don’t like its natural taste or if you prefer juices and smoothies.
The Green Juice is Organifi’s staple product made with a blend of China’s best organic spirulina. It also contains superfoods such as moringa, mint, chlorella, beetroot, matcha green tea, wheatgrass, ashwagandha, turmeric, lemon juice, and coconut water.
The ingredients work together to boost your immune health and give you more energy. Having more energy means that you won’t feel unhealthy food cravings. Curbing these cravings can help you maintain your weight or even lose a couple of pounds, according to spirulina reviews on weight loss.
We love it because it’s super-quick to make, and the ingredients blend is simply amazing. However, the juice has a strong aroma, so if you’re not a fan of minty and grassy juices, you may want to check some other product from our list.
Bulk Supplements sources its spirulina from China and manufactures the end product in the US. What gave us peace of mind is that the powder is produced according to Good Manufacturing Practices in an FDA-registered and inspected facility. Moreover, the powder is lab-tested for purity.
You can order it in standard small bags or get a gigantic 55-lb bag of spirulina and never worry about running out of it. If you make smoothies and shakes on a daily basis and use lots of spirulina powder, this is the best option among the cheap spirulina powder products.
The taste is mild and neutral, and it won’t overtake the taste of your smoothie or shake. We recommend using it in smoothies and shakes only. As great as it might be, the powder has one flaw — it clumps up when you try to mix it in plain water. You can’t capsulize it either, since the serving size is one tablespoon, which is way too much to try and put in capsules.
As its name suggests, the Amazing India Spirulina Tablets are genuinely amazing. They enhance healthy blood lipid levels, promote digestive health, and support cleansing and detoxifying.
If you’re committed to the holistic approach, these tablets are an excellent way to support and improve the overall well-being of your body and mind. Overall, they’re the best spirulina supplement that enhances cell regeneration.
The tablets are both India- and USDA-certified organic so that you can have peace of mind. They’re also halal, which makes them suitable for almost anyone.
The tablets are convenient to use — swallow with some water, and you’re good to go. You can take two tablets twice a day. The company suggests taking them on an empty stomach with warm water to enhance alkalization and promote cleansing.
The main ingredient is Indian spirulina. Other ingredients include xanthan gum, maize starch, silicon dioxide, HPMC (seal coat), and magnesium stearate.
If you’re looking for safe spirulina brands for proper body detox, MAJU is an excellent option. The powder is jam-packed with iron and vitamin B12.
Iron will enhance red blood cell production, while vitamin B12 will enhance your mood and give you more energy. So, you’ll no longer be dragging your feet throughout the day. It will also help you eat healthier, which is another essential factor in feeling energetic.
The powder is unflavored, but we’ve noticed that the taste is much less “oceanic” — it’s mild and pleasant. You definitely don’t have to hold your nose and drink it up all at once.
What we liked most is that, even though the powder isn’t organic, it’s all-natural, free from pesticides, toxins, and herbicides.
However, spirulina powder reviews don’t recommend mixing it with water, as it’ll just clump up. Luckily, it mixes well with shakes, smoothies, and other types of food.
If you prefer taking spirulina in the form of tablets, Swanson is the best spirulina brand for you. The tablets are made with Parry Nutraceuticals spirulina. It’s the first spirulina to be verified as pure and potent by the USP. Moreover, they’re easily digestible.
It’s a naturally supportive and rebuilding product. There’s one ingredient only, and that’s organic spirulina. There are no binders or additives. However, tablets don’t have the most pleasant smell, so you may want to swallow them as quickly as possible.
The tablets enhance antioxidant activity. According to the best spirulina tablets reviews, you can feel the difference in overall health. However, users say it takes about a month to feel any change, so you’ll have to be patient.
There are a couple of downsides, though. Some users have experienced heavy flatulence. Also, some users find the tablets too big and hard to swallow.
Nested Naturals has created a blend of over 40 super-healthy greens to support your immune health, promote brain power, and enhance detoxification. Spirulina and chlorella are just a part of the blend. There’s also barley grass, alfalfa, wheatgrass, green tea extract powder, and echinacea powder.
All of the ingredients work together to improve your nutrition and aid your digestion. A blend of dairy-free probiotic cultures will provide your body with enzymes that will maximize the absorption of powder’s nutrients. It’s the best spirulina to buy if you want to supercharge your day with energy.
These super greens combos usually taste like a moldy swamp, but not Nested Naturals Original. The powder tastes similar to spinach. It’s not overpowering, and it doesn’t leave a strong aftertaste. Furthermore, it mixes well with water and milk.
But, if you want to shake things up or if you simply don’t like the taste of the blue-green algae, you can try the powder in chocolate flavor, too.
Athletic Greens has created one of the most nutrient-dense superfoods powders. The Ultimate Daily Greens powder contains more than 75 vitamins, minerals, probiotics, prebiotics, and whole food-sourced ingredients.
It’s free from allergens, GMOs, pesticides, herbicides, toxins, and other dangerous ingredients. The powder is also suitable for practically any lifestyle. It’s keto-, paleo-, and vegan-friendly. It also includes over 75 highly absorbable ingredients.
The brand claims that only one scoop a day can replace your entire cupboard of supplements.
It’s one of the best spirulina supplements designed with athletes in mind. It was created by doctors, nutritionists, and naturopaths. It’s approved for use by professional athletes and Olympians as it doesn’t include any of the 270 banned substances. You can use it without any worries.
The ingredients work together to support recovery, energy, immunity, and digestion. What’s best is that it tastes like pineapple, vanilla, and papaya, thanks to the added natural flavors.
Perfect Supplements has created a blend of equal parts of spirulina and chlorella. The capsules are a convenient way to take your daily supplements with no hassle.
The product is all-natural, vegan, free from GMOs and gluten, so it’s suitable for most users. Moreover, the supplement is paleo-friendly. But not just paleo — it’s perfectly paleo. This means that the algae come from premium sources, and the final product is tested and meets all the requirements for a paleo-friendly diet.
However, most spirulina pills reviews, including ours, don’t like that the company doesn’t state where the algae are grown. Luckily, the brand tests each batch in a third-party lab. The product is also perfectly pure certified, so we’re not worried about its purity and quality.
The blend is especially beneficial to people with digestive issues, as it promotes detoxification. The capsules also promote liver health, control blood sugar levels, prevent and help fight anemia.
Landish offers high-quality powder for the best spirulina shakes for people who are active, busy, on the go, and often have no time to eat healthily. This powder is gluten- and nut-free, and it is suitable for pretty much everyone.
It provides an energy boost before a workout. You can still use it anytime you need a boost — while working, running errands, studying, etc. You can add it to your oatmeal or mix it in with smoothies, shakes, or yogurts.
It’s also one of the best spirulina products, taste-wise. The powder has a light vanilla taste, so it combines well with almost any ingredient. The brand also offers spirulina-enriched protein bars for people on the go.
We aren’t thrilled there’s no info on certificates and lab tests. However, Landish sources its spirulina from California’s Sonoran Desert, subject to the strictest health and environmental standards. With that said, we don’t doubt the purity and quality of the algae.
Adding supplements and superfoods to your diet is an excellent way to take care of your health and well-being. However, when it comes to spirulina supplements, there’s a lot you need to consider before purchasing them.
Here’s a detailed guide to help you find the best brand of spirulina.
Spirulina is a type of blue-green algae packed with nutrients. It grows free, or it can be cultivated near lakes and saltwater.
It can be used fresh as a whole food or dried and pulverized in powder, capsules, or tablets.
High–quality spirulina contains incredible amounts of proteins and amino acids. It also contains vitamins, minerals, fatty acids, glycolipids, and polysaccharides. Simply put — it’s a real superfood.
We mentioned that spirulina is packed with nutrients, but let’s break down its nutritional profile and see what exactly it consists of:
It truly deserves the title of superfood!
Not even the best–quality spirulina can substitute traditional therapy or be used as a standalone therapy. However, if used as a supplement, it can significantly help:
There’s a significant number of companies that use low-quality spirulina. Some even go as far as to use algae similar to spirulina to trick the users. None of those companies are on our spirulina reviews list. Nonetheless, here are a few tips on recognizing quality spirulina.
To be sure you’re getting the right product, choose the one that has Spirulina, Spirulina platensis, or Arthrospira platensis on the label.
Also, pay attention to the content. Tablets and capsules should have at least 98% spirulina content. Similarly, the powder should be 100% spirulina.
It goes without saying you should avoid additives and fillers.
Typically, spirulina powder comes in resealable pouches. They’re convenient, lightweight, and easy to store — nothing to worry about.
However, if you’re buying spirulina tablets and capsules, make sure it comes in a brown, medical-grade bottle with an airtight seal. It’ll protect the algae from going bad in the sunlight.
Spirulina grown in the wild produces microcystin as a way of defending itself from predators. This hepatotoxin can be toxic for your liver if taken in high doses.
On the contrary, spirulina grown in controlled conditions has much lower microcystin levels. So, it doesn’t pose any danger.
However, just to be sure everything’s alright, go for a company that tests its products in a third-party lab.
The best source of spirulina is California, followed by India and China.
Good spirulina has a dark green matte color and a distinctive fishy flavor. If the powder is shiny or dusty, it means that spirulina was crushed, compacted, and covered with a coating to prevent it from crushing again.
While this is nothing to be alarmed about, you should be aware that spirulina loses some of its nutritional benefits this way.
Additionally, if the powder’s aroma is too strong and repulsive, spirulina might be spoiled by oxidation.
How fast spirulina dissolves in water will signify how many nutrients your body can absorb from it. The ideal spirulina superfood powder dissolution should not be too fast nor slow. That way, the algae can reach the stomach, and the small intestine can absorb all the needed nutrients, not just have the supplement pass through your digestive system.
While spirulina doesn’t contain the usual allergens, such as dairy, egg, nuts, wheat, soy, etc., the facility where it’s produced might. Another trace element that could creep into your spirulina supplement is iodine.
Just be sure to check the label for allergen warnings to avoid any allergic reactions.
While in most cases organic means better overall quality, when it comes to spirulina, it makes almost no difference.
It all comes down to the growing process and your personal preferences. Organic cultivation may mean using animal-waste for fertilization. Therefore, if you’re a vegan, you may want to go for a non-organic option.
Or, if you’re keen on going organic, make sure the company uses animal-friendly practices.
Even the highest–quality spirulina has a fishy flavor. It usually isn’t a big issue for most users. However, a small number of people can’t stand the aquarium-like taste of the algae.
Now, we recommend using the purest form of spirulina. Still, there are flavored options if you absolutely can’t stand its natural taste. As long as the company uses natural flavors, there’s no risk of decreasing spirulina’s nutritional benefits. But note that added flavor may increase the caloric value.
Typically, spirulina comes in the form of powder, tablets, and capsules. You can also find it in different energy bars, healthy snacks, and mouth-watering keto shakes. Which form you’ll take depends entirely on your preferences, as spirulina is nutritious in all its forms.
Pills and capsules are more convenient to carry, and you can swallow them wherever you are. On the other hand, the powder is more versatile. You can blend it into your protein shake and smoothie, add to your bread mixture, or even sprinkle over a salad.
Spirulina capsules and powder can also contain chlorella — another very potent type of algae. Like spirulina, chlorella, too, is packed with nutrients. It has ten times more chlorophyll than spirulina and 50 times more chlorophyll than wheatgrass.
It purifies blood and filters out impurities from our bodies. Moreover, it has high levels of nucleic and amino acids, as well as peptides.
The combo is a great health booster.
As we mentioned, spirulina has a dense concentration of nutrients. It’s one of the most nutritious foods on the planet. Here are just a fraction of its health benefits:
Spirulina has been used successfully in dosages that range from one to ten grams of raw powder per day.
Since we still don’t have enough high-quality human studies on spirulina, it’s best to follow the manufacturer’s directions. It’s best to start with a low dosage, see how your body reacts, and gradually increase or decrease the intake.
You should also consult your physician.
Spirulina is generally considered safe for healthy adults, provided it’s pure and high-quality. It poses no risk for side effects.
However, even if you’re planning on consuming the best spirulina on the market, consult your doctor if you’re:

Spirulina is suitable for an array of reasons, the main one being its nutrient-dense profile. It provides your body with all the necessary minerals, vitamins, amino acids, fatty acids, and more.

Spirulina brings a wide array of benefits. It can boost your overall wellness and health.
It’s also great for fighting fatigue and upping your physical performance. It also soothes inflammation, lowers cholesterol and blood pressure, and feeds your body all the necessary vitamins, minerals, amino and fatty acids, and other essential nutrients.
The fishy taste of spirulina isn’t for everyone. Luckily, you can mask it easily. You can mix in the powder into a meal replacement shake, smoothie, oatmeal, sprinkle it in dishes, mix it with bread and healthy cookies batter, etc.
We mentioned a couple of times that spirulina is very rich in protein. Protein-packed foods and supplements increase your alertness, so it’s best not to take them late in the day, or you may end up staying awake for a very long time.
We recommend you take spirulina at least four hours before bed. Other than that, it’s up to you. You can take the best spirulina supplement of your choice before or after a workout or whenever your energy levels are low.
