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 Product Recommendations 1 - Transparent Labs Prebiotic Greens
Transparent Labs is possibly 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.
CONS 2 - 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 , it claims to provide the right nutrition levels for a better heart, brain, and immune health.
That was quite a convincing bonus for us.

3 - 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.
CONS 4 - 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 .
This also seems to be a solid option for people looking for some mental energy, which we saw highlighted in several reviews.
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.
CONS 5 - 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.
Unlike some of the other brand options, we found that it wouldn’t just stir into the water but mixed well in a shaker.
CONS 6 - 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 .
This may also be one of the better spirulina supplements to boost your amino acid intake due to the rich protein content.
CONS 7 - 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.
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.
CONS 8 - LuRoot Organic Spirulina Supplement
If you’re aiming for a higher dosage, then powder might become the less favored option. LuRoot solves this with organic spirulina capsules that seem to be easy to swallow.
This way, you could take more capsules to get more of the energy boost reported by quite a few users.
We should also mention that it’s one of the cheaper options if you’re on a budget.
Despite being a capsule form, we did find that you eventually get a bit of fishy smell.
Take it before a meal, which seems to avoid this.
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.
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.
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.
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.
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 .
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. 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.
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.
Doesn’t sound like the nutrition your body would need to boost immunity, right?
Is it safe to take spirulina every day?
Who should not take spirulina?
What does spirulina do to the body?
Is spirulina safe for kidneys? What's Our #1 Spirulina Supplement?
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 Transparent Labs Prebiotic Greens in the top spot.
The combination of spirulina and prebiotics just seems to give it the edge when it comes to digestive, immune, and heart health.
