Chlorella supplements are similar to chlorophyll supplements, and there’s a good reason for that. 

Chlorella is a type of algae which is responsible for turning the water in an aquatic environment green, and contains chlorophyll which helps plants with photosynthesis.

It is often compared to spirulina too, as a result of how nutrient-rich it is and its detoxifying properties.

If you’re looking to load up on nutrients, minerals, and vitamins, then chlorella supplements are a quick and easy way to do so.

Sunfood Chlorella Tablets (👑 Top Pick)

We believe the best chlorella supplement is these chlorella tablets from Sunfood.

This supplement from Sunfood includes 225 tablets of 100% pure chlorella, with each tablet offering 250mg. The recommended serving suggestion is 3-4 tablets 3 times a day, which means one bag provides roughly 18 servings. It’s a non-GMO, vegan, and gluten-free option, which provides all of the health benefits associated with chlorella such as immune support and better blood health.

Sunfood’s tablets are a quick and easy way to get your fix of the green algae superfood throughout the day. The main benefits of taking this supplement are detoxifying and alkalising the body, as well as nourishing it with many of the nutrients and minerals it needs to function at its best. What makes these tablets stand out is that they are processed from pure chlorella powder, before the cell walls are broken with a chemical-free centrifugal process. Breaking down these cell walls allows for optimal nutrient absorption, and with each tablet there is no extra filler or additives padding them out.

Another interesting thing about these tablets is that they are best enjoyed as part of a healthy smoothie. Given that they are small, you have the option of either taking these tablets on their own with water, or mixing them in with a nutritious smoothie. Since you’ll need to take up to 12 a day to get the most out of them, it’s nice to be able to take them in a variety of different ways.

Many past customers who take this chlorella supplement on a regular basis are satisfied with the results. Specifically, happy customers praise the tablets for helping with everything from digestion to mood.

NOW Supplements Chlorella (💊 Best Chlorella Tablets)

With an excellent reputation for producing health supplements, NOW doesn’t disappoint with its conventional chlorella tablets.

If you’re looking for the kind of tablets you can take with a glass of water, then there are few better chlorella supplements than this one. NOW is a brand known for its quality, yet also provides great value for money with its products. There are 3 different buying options available for its chlorella tablets, so you can buy a container of 60, 120, or 200 tablets. The tablets are non GMO, vegan and vegetarian friendly, and soy and corn free. They are made from the broken cell wall of chlorella, as well as cellulose, silica and magnesium stearate. Each tablet contains 1,000 mg of chlorella, and the serving suggestion is 3 tablets a day, so a 120 tablet container should last you 40 servings total.

Unlike the small tablets from Sunfood which can be mixed easily with smoothies and other drinks, the tablets from NOW are more like those you’d typically expect from a health supplement. You’ll only need to take 3 of these tablets a day, given that each one contains a high amount of chlorella at 1000mg. This makes it one of the most convenient ways of supplementing with chlorella, since you can take them in an instant and get your daily dose.

The tablets of chlorella are GMP quality assured, and have been granted NPA A-rated GMP certifications, which means that every element of the NOW manufacturing process has been scrutinised. This should ease any concerns you may have about the quality of the supplement.

Amazing Grass Green Superfood (⭐ Best Chlorella Powder)

Taking a chlorella supplement in powder form is a good option if you can’t stomach capsules and tablets, and this option from Amazing Grass is as good as any.

This isn’t a straightforward chlorella powder, but a potent combination of all kinds of healthy greens and superfoods. If you’re looking for a powdered health supplement that can give your body the greatest chance of functioning well, then this Green Superfood powder should do the trick. The supplement is loaded with a green food blend, antioxidant blend, probiotic blend and a fiber blend. Within the green food blend you’ll find organic cracked cell wall chlorella, and some other noteworthy inclusions in the supplement include organic spirulina, organic flax seed, and organic maca root.

By combining all of these various superfoods and healthy greens, Amazing Grass have created a health supplement that is the equivalent of 2 full servings of fruits and vegetables in 1 scoop. This helps to round out the benefits you get from taking it, rather than just a very highly concentrated dose of chlorella. You might be grateful for this too, since many people report stomach issues from taking highly concentrated chlorella supplements. The fact that it’s blended with many other ingredients could make it easier on the stomach.

This supplement is Certified Organic by CCOF, gluten free, sugar free, non GMO, and kosher. A single packet contains around 476g, and a single serving size should be 8g, this means you should roughly expect to get 60 or so servings out of it. In each 8g serving, you’ll get around 5.7g of the green food blend, in which will be the cracked cell wall organic chlorella.

What’s convenient about this supplement is that you can enjoy it in many ways. You can add a scoop to water, milk, or juice for a simple option. Or, if you’re looking to be a bit more adventurous with your supplementation, you can blend the powder up into your favorite smoothie or bake with it.

Past customers praise this green superfood supplement because of how easy it blends with drinks, and because it provides all of the greens you need for the day. Some say it alleviates feelings of fatigue and sluggishness, while others claim that they can’t go a day without it due to its positive effects on acid reflux and the large quantity of nutrients it provides.

What is the Best Chlorella Brand?

Rather than list out every reputable chlorella supplement brand, we thought it’d be helpful for you to know how to identify the good and the bad ones.

We’ll suggest a couple of brands too, but oftentimes with health supplements it’s better to know what exactly you’re looking for rather than blindly trusting a single brand.

  •  Cracked wall

The best chlorella supplements will state on the label that they have ‘cracked wall’ chlorella, which might seem odd at first, but it’s necessary for the body to properly digest the green algae.

  •  Organic

While it isn’t very common to have organic chlorella supplements, there are a few, like the one from Amazing Grass which offer this in their supplements.

  •  3rd party tested

Seeing that a product isn’t 3rd party tested or quality assured can be a red flag, because it means the manufacturing process hasn’t been scrutinised or checked to see if it meets industry standards.

  •  User reviews

While user reviews on Amazon aren’t always 100% reliable, they can be one of the only real ways of knowing if the supplement is effective or not.

  • Chlorella pyrenoidosa 

If you want the very best, then look out for chlorella pyrenoidosa on the supplement label.

This version of the green algae has a higher concentration of nutrients than the alternative, chlorella vulgaris.

  1. NOW 

NOW is a brand with a lot of clout in the health supplement industry, so you know its chlorella supplement is reliable.

This is backed up by many satisfied customers, and the 1000mg tablets make for a very convenient way to get your daily dose of chlorella.

  1. Sunfood

Sunfood is a brand which focuses on raw, non-GMO superfoods, and its chlorella tablets can be taken with water or mixed into drinks.

The tablets are made using high quality chlorella pyrenoidosa too.

  1. Amazing Grass

Amazing Grass is a brand which also specialises in raw superfoods, and its green superfood blend is a great way to get in your fix of chlorella.

This is a brand that began as a family-project in Kansas over 3 generations ago, and has now blossomed into a large health supplement provider.

Ultimate Guide to Choosing a Chlorella Supplement

Chlorella supplements can be helpful to take for a number of reasons, and come in a variety of forms.

In this guide we’ll go over what exactly chlorella is and why it is used in supplements, as well as the most important benefits it provides and how to take it.

What is it?

Chlorella is a green algae which is compared to spirulina, and there’s a good reason for that.

Both algaes are becoming increasingly popular due to their inclusion in health supplements, and their many alleged health benefits.

Chlorella and spirulina are both incredibly nutrient-dense algae, which is one of the main reasons why they are used in health supplements.

However, when you supplement with chlorella, you aren’t really taking in the whole single-celled freshwater algae.

Due to the presence of a hard cell wall, health supplement manufacturers have to break it down before it is digestible for humans.

As a result, don’t be discouraged if you see the terms cracked or broken cell wall chlorella on the supplement label, as these are the only ways you’ll be able to digest the green algae.

The most common ways to take chlorella supplements are as capsules, tablets, and powders.

Chlorella Benefits

Now that you have a clearer idea of what exactly you’re getting when you buy a chlorella supplement, let’s take a look at some of the main health benefits it can provide.

Boosts Immune System

We all strive to have a healthy immune system, but sometimes it’s difficult to get everything we need through diet alone. Sometimes supplements are necessary to top us up and give us what we need to fight off sickness.

Some evidence has shown that chlorella supplements can improve immune function, but this evidence is inconclusive, and appears to depend on age and other factors.

However, whatever you can do to boost your immune system is worth it, especially if it’s as convenient as taking a pill or 2 a day.


One of the most noteworthy characteristics of the green algae, and the main reason it is used in health supplements, is because of how nutrient-dense chlorella is.

Just like spirulina, chlorella has plenty of vitamins, minerals, and nutrients to offer when taken as a supplement.

This nutrient-rich profile has also granted chlorella with the prestigious ‘superfood’ title.

As far as what exactly chlorella contains, it’s high in vitamin B12, C and other B vitamins.

It has a high level of protein (50-60%) and counts as a complete source of protein, which means it has all of the 9 essential amino acids.

Then there’s the high content of iron, the antioxidants, omega 3s, fiber, and minerals such as magnesium, zinc, and potassium.

All in all you can get a lot of nutritional value out of chlorella, which can make a chlorella supplement a key part of your daily diet and help you get everything your body needs to thrive.


One of the biggest claims about chlorella supplements is that they can help detoxify or cleanse the body.

We’ve all heard of detox diets and juice cleanses, but you might not need to undergo such radical approaches if you supplement regularly with chlorella.

The way chlorella can help detoxify the body is by binding to heavy metals like lead and cadmium which can be toxic.

Certain environments and pollution can increase the amount of heavy metals you are exposed to, so it’s worth taking a chlorella supplement if you work in mining or are regularly around air pollution.

Helps Lower Cholesterol

Chlorella supplements may be able to lower cholesterol, more specifically, LDL cholesterol and triglycerides.

This has been shown to be most effective in people who already have high blood pressure or high cholesterol.

Antioxidant Content

Antioxidants are very useful and are found in several components which make up chlorella, including vitamin C and chlorophyll.

As a result, there’s a possibility that by supplementing with chlorella you could boost your ability to fight off chronic disease.

Moderates Blood Sugar and Pressure

Finally, chlorella supplements can potentially help moderate both blood pressure and blood sugar level.

This is likely due to the potassium, calcium, and omega 3s in the chlorella.

Frequently Asked Questions About Chlorella Supplements

Is chlorella worth taking?

We’d argue that, yes, chlorella is definitely worth taking.

While you might not have heard of the nutrient-dense algae before, it is comparable to spirulina in many ways, which is a very popular ingredient for health supplements.

The main reasons you should consider taking chlorella are that it’s full of nutrition for the body, it can help you detoxify, and it could boost immune function.

What is the best way to take chlorella?

Just because some people prefer one way of supplementing, it doesn’t mean it will be the best way for you.

To determine what the best way for you to take chlorella is, you’ll need to take into account lifestyle factors, convenience, and the concentration you’re looking for.

Each type of chlorella supplement has its own upsides and downsides, as we explore in this guide.

Is chlorella good for your liver?

There is some evidence to suggest that, yes, chlorella could be good for your liver.

Chlorella supplements have been proven to improve the liver health of those who suffer with some form of liver disease, but it’s relatively unknown whether or not they can help those with healthy livers.

As with just about any health supplement, there’s a chance that taking chlorella could result in some unpleasant side effects.

Known side effects include nausea, and a lack of regulation for the supplements.

The main reason you might struggle with this supplement is due to how nutrient-rich it is, and this could upset the stomach.
