My dietitian always reminds me of the health benefits of spirulina powder -- it boosts your immune system and helps your body remove free radicals and heavy metals.
However, there are too many products available that might contain toxins or use processes that damage the nutrients.
So, we set out to do some research to find the best and safest options available.
Let’s get to it.
Our Top Products (September 2023)
1 - Live Conscious Beyond Greens
Live Conscious, formerly known as Livewell, continues to impress with their latest offering - Beyond Greens powder, securing the top spot on our list.
This exceptional green brand demonstrates that an all-natural superfood greens powder can be both nutritious and delicious.
As someone who isn't typically a fan of tea, I personally vouch for the light matcha flavor they've achieved.
Beyond Greens powder is a powerful blend of superfoods, including milk thistle, probiotics, and various mushrooms.
Its claim to promote gut health and boost the immune system comes without any unwanted additives.
- Non-GMO, gluten-free, soy-free, and dairy-free, catering to those with food intolerances
- Comprised of all-natural, high-quality ingredients
- The unique and refreshing light matcha flavor
- Low calorie content per serving
- Limited to a single flavored option
The Beyond Greens powder is a soy-free and gluten-free formula, enriched with vital nutrients like vitamin C.
This makes it an excellent choice for supporting the immune system and reaping the benefits of green drinks.
2 - Transparent Labs Prebiotic Greens
Transparent Labs is possibly one of our favorite supplements company because they are completely open and honest about the ingredients.
And based on the combination of spirulina, chlorella, and prebiotics, our team came to the conclusion that this may be one of the best spirulina supplements.
It claims to be low in toxins and has no artificial additives that could cause gut flora problems.
- Combines quality spirulina with chlorella for better detox
- Provides a blend of 8g prebiotic fibers to help digestive health
- Claims to improve gut flora to help with nutrient absorption
- Contains no artificial ingredients or flavors
- It has a slightly sweet flavor
Just try to water it down a bit as some people find the flavor to be a bit sweet.
3 - Organifi Green Juice
This is the first pure organic spirulina supplement on our list, where the entire product is sourced organically.
But it also goes beyond just spirulina.
With added plant super greens from many different sources [1], it claims to provide the right nutrition levels for a better heart, brain, and immune health.
That was quite a convincing bonus for us.
- All ingredients are from organic sources for higher quality
- Combines a long list of other plant super greens for an immune boost
- Great discounts when signing up for a spirulina supplement subscription
- You need to shake it for a bit longer to get it fully mixed
One thing we did notice is that it might be a bit stubborn to fully mix, so you may want a shaker handy.
4 - Pure Hawaiian Spirulina Powder
This organic spirulina is grown and packaged in the USA with the aim to give people the added peace of mind that it’s not exposed to toxins.
We also tried mixing it with fruit salad and cereal, which seemed to work pretty well. Just take it easy at first to make sure you don’t get too much of the algae taste.
- High-quality spirulina from blue-green algae made in the USA
- Suitable for mixing into morning cereals
- Also available as spirulina tablets if you’re not a fan of the powder
- It does have a slight aftertaste
Compared to the above option, we did find that there is a bit of an aftertaste, but you could water it down a bit more.
5 - BN Organic Spirulina Powder
We’re on a roll with organic spirulina powder, and what stood out for us with this product is the low heat processing [2].
This also seems to be a solid option for people looking for some mental energy, which we saw highlighted in several reviews.
- Claims to use a low heat process to maintain nutritional benefits
- Many reports that it may also promote mental alertness and focus
- Also available as spirulina tablets which could be more convenient
- It’s not the best tasting product
The only thing we found is that the taste could be improved as you do tend to get the sense you’re drinking algae.
But, you could always order this in tablet form instead.
6 - NOW Certified Organic Spirulina Powder
This USDA certified organic spirulina powder comes from a company that claims it’s entirely sourced from sustainable production facilities.
This may also explain why they highlight it as pure spirulina with some added vitamins like A and B12 for heart and immune health.
- Certified USDA organic sources of ingredients for added peace of mind
- Claims to be one of the most sustainably sourced spirulina supplements
- Good source of vitamin A and B12
- You’ll need to shake it a lot to fully mix
Unlike some of the other brand options, we found that it wouldn’t just stir into the water but mixed well in a shaker.
7 - Sari Foods Organic Spirulina Powder
Sari Foods brings us this quality spirulina product where the content is sourced from freshwater lakes with optimum conditions for low toxicity.
There seems to be a lot of research and information on toxic substances in algae, which could pose significant health risks [3].
This may also be one of the better spirulina supplements to boost your amino acid intake due to the rich protein content.
- Claims to be harvested from freshwater lakes for lowest levels of pollutants
- Provides a good boost of protein
- Good source of vitamins A, B12, and K
- The full dose may taste a bit intense
One thing I would suggest is to mix the powder with quite a bit more water as this green superfood tastes quite intense at full dosage.
8 - Bulksupplements Spirulina Supplement
This is another supplement company that we have quite a bit of experience with, and it could be a great choice for athletes who need something rich in protein.
It covers quite a wide range of amino acids with some pretty good savings available if you buy one of the larger bulk order bags.
- Uses organic spirulina powder for higher quality
- Available in a bulk order container for some good savings
- A good dose of essential and non-essential amino acids
- Some reports about the bags not sealing properly after a while
One thing we did find with the seal on the bags is that it’s sometimes a bit difficult to properly seal.
So, you might want to source a different type of container.
9 - Natural Nutra Organic Spirulina Supplement
These vegan tablets contain a rich dose of organic spirulina, which has the advantage of being able to carry them with you to take at different times of the day.
Releasing the superfood in this way could help sustain your energy levels throughout the day.
It’s also nice to see a money-back guarantee, so if you don’t like the results, you don’t have anything to lose.
- Vegan tablets to make timing your intake easier
- Available in a large bottle with bulk order discounts
- Comes with a 30-day money-back guarantee
- For the full dosage, you’ll need to swallow six tablets daily
To get the full serving, you’ll need to take quite a few tablets, which may be a bit much in one go.
10 - Dr. Mercola Spiru-Blue
The final spirulina supplement on our list also has a certified organic label for a more natural source of nutrients without common toxic stuff.
It also doesn’t contain some of the allergens that many people suffer from, like soy and gluten.
- Uses only organic ingredients to limit harmful heavy metals
- 90-day money-back guarantee for added peace of mind
- Free of gluten, soy, and GMO ingredients
- You need to remember to space out four tablets daily
Now, to get the full health benefit of the nutrients, you’ll need to take four tablets. That might be best to do at different times, as some people might struggle to swallow them all in a row.
Buyer’s Guide - Best Spirulina Supplement
When you’re looking at different spirulina products, there are a few things that might ultimately make up your mind.
Here are four important things.
1. Check For Certified Organic Labels
If possible, choose certified organic spirulina.
Not because it has some magically high nutrition content, but it could ensure that you’re exposed to fewer toxic materials.
The algae that are harvested would also be dried, purified, and concentrated, so any toxins could be further concentrated as well.
Organically grown gets a big thumbs up from us.
“Spirulina can be digested easily because of its structure where the cells do not have tough, fibrous walls.”
- Katherine Marengo, Registered Dietitian

2 - Avoid Artificial Additives
Try and get a pure spirulina powder so that your body only gets natural nutrients.
We saw it in quite a few products where food coloring, flavors, and sweeteners were added.
These have no benefit from a nutrition perspective and could potentially upset your healthy gut bacteria [4].
3. Potential Side Effects
If you don’t buy organic spirulina, then taking large doses in the long term could potentially put you at risk of being exposed to heavy metals [5].
Even if the risk isn’t high, it’s best to avoid such products.
In rare instances, people could develop allergic reactions, and if that happens, then you may want to talk to your doctor.
Overall, though, you’ll probably find that the health benefits far outweigh any possible side effects.
“Doses up to 19 grams per day have been used safely for up to 2 months. Lower doses of 10 grams per day have been used safely for up to 6 months. “
- WebMD.com
4 - Compare The Macros Per Serving
Believe it or not, but we found more than one company that added quite a high amount of sugar to each serving [6].
Doesn’t sound like the nutrition your body would need to boost immunity, right?
So, always check the label for all nutrients, and not just protein. If it has a lot of carbs, then it might not be as pure as you’d want it to be.
FAQs
Is it safe to take spirulina every day?
Yes, it’s safe to take spirulina every day as long as you stick to the recommended serving size of the product. If you aim for 10 grams of spirulina powder per day, then you should be safe for longer periods.
Who should not take spirulina?
Anyone with allergies to seafood, seaweed, algae, or chlorella should not take spirulina. Even in a pure form, this could trigger allergic reactions along with an upset stomach and nausea.
What does spirulina do to the body?
Spirulina has been shown to help the body improve its immune responses, which could help at different times of the year to fight disease. There is also increasing information from studies that it’s rich in antioxidants, which could help detoxify your blood and organs.
Is spirulina safe for kidneys?
Yes, spirulina is generally considered safe for kidneys. With some studies showing that it could reduce blood pressure, this could even have a positive effect. However, if you have some sort of kidney disease, then it’s always best to consult your doctor first.
Which One Of These Best Spirulina Supplements Will You Choose?
Of all the spirulina supplements we tested out, it came down to two products for the top spot.
Ultimately, only a vote was able to settle the debate, and we put Live Conscious Beyond Greens in the top spot.
Its mix, enriched with echinacea, rhodiola, milk thistle, probiotics, and four varieties of powerful mushrooms, provides the edge with harmonious gut health, whole-body detoxification, and clean energy while supporting a healthy immune system.
