Everyone’s talking about liquid chlorophyll these days.

That’s especially true on TikTok, where videos about chlorophyll drops and chlorophyll water generate millions of views. People claim that the green pigment, found in all plants, reduces inflammation, cholesterol, anemia, acne, bad breath and more.

It all begs the question: Are these supplements worth the hype? Do well-designed research studies support the claims? If so, do some chlorophyll supplements work better than others?

We asked highly respected nutrition experts those questions, and you’ll find their answers ahead.

On top of that, in this comprehensive supplement review, we’ve also included picks for the top seven chlorophyll products on the market. Before you dig in, however, we need to point out an important caveat. Chlorophyll is found in all green plant foods. As a result, you’ll find picks for comprehensive greens powders—often made from microalgae and/or green veggies—as well as from chlorophyll specific products.

Transparent Labs got its name because the company values transparency. They not only ask outside companies to test their products for purity and potency, but also post those findings publicly for consumers to peruse.

On top of that, Transparent Labs claims to only utilize ingredients that they can back up with published research. This prebiotic greens power is one such product.

It’s packed with two nutritional powerhouses—spirulina and chlorella—both of which are rich in chlorophyll. Unlike land plants, these marine microalgae grow extremely quickly, which makes them ideal fodder for supplement companies. They’re rich in protein, which is rare in the plant world, reports Harvard Health. That helps explain why just one scoop of this powder contains half as much protein as the typical egg.

In addition to the two chlorophyll-packed marine greens, this powder also boasts 8 grams of fiber from acacia, green bananas, chicory root, and Jerusalem artichokes. It’s thought that these prebiotic fibers help to promote digestive health.

The greens powder earned our best overall award because it packs so much into just one, relatively affordable scoop. You’re basically getting two different supplements—a greens powder and a prebiotic—all in one.

On the manufacturer’s website, 214 people have reviewed the powder, giving it an average of 4.5 stars. Most seem to enjoy the taste. As one reviewer wrote, “Best tasting green product I've had. I've had both Mango and unflavored. Both are good enough to drink with just water. Gentle on digestion with noticeable improvement in overall wellness.”

Mix one scoop with eight ounces of water, juice or another beverage. Drink up to three times a day.

Pros:

• Vegan and peanut free
• Backed by third-party testing for purity and potency
• Easily mixes with water
• Great taste

Cons:

• Some reviewers complained of gas after taking this greens powder
• At $1.50, this one is on the pricey side—but you also get a lot of bang for your buck

Named after a Greek island, KOS is all about sustainable nutrition. That’s why their products are all plant based. As the company says on its website, “the closer you get to eating actual sunlight, the more food there is to go around.”

This particular KOS product is pure spirulina, a powerful marine source of chlorophyll. In addition to being loaded with protein and other nutrients, spirulina also grows quickly, making it even more sustainable than most plant foods.

We awarded it best “herbal” because it’s 100 percent plant based as well as certified organic. That it’s produced in an NSF-certified facility means that you can rest assured that extra precautions were taken to ensure product quality and safety. The USDA Organic stamp means the spirulina was grown and processed according to federal organic guidelines. In other words, synthetic fertilizers or herbicides were not used.

To date, no one has reviewed this product on amazon, and only about 56 people have done so on the manufacturer’s site. They’ve rated it 4.9 out of 5 stars, and seem to enjoy the texture and flavor. Some have even developed a spin-off drink that includes a squeeze of half a lemon and a sprinkle of cayenne.

Pros:

• 60-day money-back guarantee
• Budget friendly
• Organic

Cons:

• Lacks an abundance of customer reviews

• Moringa Leaf per serving: 1,000 milligrams

Like spirulina, moringa grows quickly and is drought resistant, making it highly sustainable. (Interestingly, the seeds of the plant have been used to purify river water in poor countries.)

Also like spirulina, moringa is a powerfood, naturally rich in many vitamins, minerals and plant nutrients that are thought to have anti-inflammatory and antioxidant effects in the body. And, the plant might help reduce risk of developing type 2 diabetes, according to research funded by the National Institutes of Health,

The KOS moringa product is one of the more budget-friendly chlorophyll pills around, as well as one of the few that derives its chlorophyll from moringa.

Take two capsules daily, with or without food.

Pros:

• Gluten, dairy, and soy free
• Plant-based vegetarian capsules
• 60-day, money-back guarantee
• Free shipping on orders $45 and over

If you listen to the Huberman Lab podcast, then you’re likely familiar with AG1. Stanford neurobiologist Andrew Huberman sits on the company’s science advisory board, as do many other health influences like Peter Attia, MD, of The Drive podcast.

AG1 is a wee bit cagey about its formula, calling things “proprietary blends,” which means they do not disclose the exact formula. That said, the product’s list of ingredients includes 75 different whole foods. Among the green chlorophyll foods, you’ll find spirulina, lecithin, wheatgrass, chlorella, and kelp, along with medicinal mushrooms like ashwagandha, reishi and astragalus. 

For more information, check out our complete AG1 review.

It’s perhaps the most comprehensive greens powder on the market, offering up a hefty portion of many different powerfoods, all in one scoop.

On Amazon, the product has earned a 4.5 out of 5 star rating, based on more than 3,000 reviews. As one reviewer wrote: “The taste is almost creamy in texture and you can taste the slight undertone of the good healthy chocolate that they use. It has absolutely no grassy taste.”

One drawback: Many reviewers have commented that the drink is a little “gritty.”

Mix one scoop in 10 ounces of cold water. Drink on an empty stomach, first thing in the morning.

Pros:

• Gluten, egg, sugar, peanut, corn and dairy free
• GMO free
• Contains a wide abundance of superfoods

Cons:

• At $3.30 a serving, this is on the more expensive side.
• Has a gritty texture

Life Extension is a heavy-hitter in the supplement world. The Fort Lauderdale-based company has been around for 40 years, publishes a monthly health magazine, and staffs a team of naturopaths, nutritionists, and nurses who answer customer questions and dispense wellness advice—for free.

This particular supplement is 100 percent chlorophyllin, a semi-synthetic form of chlorophyll that contains sodium and copper. Various studies have linked chlorophyllin supplementation to improved gut health, reduced cancer risk, and even reduced body odor.

When it comes to pure chlorophyllin, capsules tend to be less messy than either tablets or powders, both of which can leave behind a green residue on your hands or in your mouth. At $.18 a pill, this is among the least expensive chlorophyll supplements around.

On Amazon, the supplement has earned 4.4/5 stars, based on more than 500 ratings. There you’ll find many glowing reviews from happy customers who’ve used the supplement to clear up a wide range of health issues.

Take one capsule three times daily with food.

Pros:

• High-potency
• Vegetarian capsules
• Full year money back guarantee
• Non-GMO

Cons:

• Three daily capsules is a lot for people who struggle to swallow pills

Best Vegan Chlorophyll Drops: Mary Ruth’s Chlorophyll Liquid Drops

Key features & specs

• Chlorophyllin per serving: 50 milligrams
• Nutrition facts: 50 milligrams Chlorophyllin
• Form: Liquid drops
• Flavors: Peppermint
• Certifications: Manufactured in a GMP-certified facility
• Subscription: Monthly for 10% off
• Key ingredients: Sodium Copper Chlorophyllin
• Sweeteners: Peppermint oil
• Best for: Vegans, vegetarians, people who struggle to swallow pills, people who dislike the experience of greens powders.
• Price per serving: $.66

A certified health educator and nutritionist, Mary Ruth launched her company because she wanted supplements for her four children that were non-GMO and gluten free.

These vegan liquid drops contain chlorophyllin, a semi-synthetic form of chlorophyll that has been altered to make it water soluble.

You might wonder: Aren’t all greens products considered vegan supplements? After all, they come from plants, right?

Not necessarily. Many supplements use small amounts of animal products. Tablets and capsules, for example, often include gelatin (an animal product) as part of their coating. Many powders and liquids include glycerine (from beef or mutton) as a preservative and a sweetener.

The Mary Ruth’s drops, however, contain none of those substances. In addition to chlorophyllin, the drops contain purified water, vegetable glycerine (likely from soybeans) and peppermint oil (as a flavoring). None of the additives come from animals or animal products.

As a dropper, this is great for people who struggle to swallow pills and who dislike the experience of greens powders. Shake before each use. Add a full dropper to 16 ounces of water or directly into your mouth, once daily.

On Amazon, the product has more than 12,000 ratings, with an average 4.5/5 stars. There you’ll find review after review from happy customers who say the product cleared up their body odor, acne, bloating, fatigue and much more.

Pros:

• Vegan
• Free of dairy, gluten. Nuts, nightshade vegetables and sugar
• Organic
• Non-GMO

Cons:

• At 50 milligrams per serving, this is about half the potency of the Life Extension brand
• Some customers have complained that the product stains their teeth

Best Chlorophyll for Altitude: Herbs Etc. ChlorOxygen

Key features & specs

• Chlorophyllin per serving: 50 milligrams
• Nutrition facts: 5 calories, 4 milligrams sodium, 2 milligrams copper, 50 milligrams chlorophyllin
• Form: Liquid drops
• Flavors: N/A
• Certifications: USDA Organic
• Subscription: N/A
• Key ingredients: Chlorophyllin
• Sweeteners: Vegetable glycerine, maltodextrin, natural flavors
• Best for: People who are sober and/or in recovery, people who dislike swallowing pills
• Price per serving: $0.22

Herbs Etc. has been making herbal supplements since 1969. Unlike many companies, however, Herbs Etc. extracts, dries, and grinds all of its products in-house, without relying on outside vendors to supply these raw materials.

Their ChlorOxygen supplement contains 50 milligrams of chlorophyllin, a semi-synthetic form of chlorophyll.

Herbs Etc. markets the product for high altitude and energy. That said, the product is chemically similar to other chlorophyllin supplements on the market.

What sets the Herbs Etc. product apart, however, is this: It’s free of alcohol. Many liquid extracts use alcohol as a solvent and preservative. In contrast, Herbs Etc. uses cold-processing to remove the alcohol in this product and other products in its alcohol-free line. That makes it a great choice for anyone who is sober or in recovery.

On Amazon, the product has about 260 reviews, earning 4.6 out of 5 stars. Many reviewers claim the product has helped with their energy levels. As one person wrote, “I feel like it has awaken a new life within my blood cells. I have been struggling for years with dizziness, breathing and energy…I am not saying that it has 100% cured my ailments, but I can honestly say that it has significantly helped.”

To use it, shake well. Then dilute 18 drops in water, then drink. Take it twice a day.

Pros:

• Non-GMO
• Alcohol free

Cons:

• At 50 milligrams per serving, this is about half the potency of the Life Extension brand

What Is Chlorophyll?

You may remember learning about chlorophyll way back in high school biology. It’s the green substance that plants use to make food during photosynthesis. It’s present in all green vegetables—such as broccoli, kale, Brussels sprouts, parsley, green beans, spinach and green peppers—as well as green marine plants like kelp and algae.

For many supplements—including ones listed above—you won’t find chlorophyll listed on the label. Instead you’ll see other green vegetables (such as broccoli), green marine plants (such as spirulina), or chlorophyllin, a semi-synthetic form of chlorophyll that contains copper.

Benefits of Chlorophyll Supplements

The research on chlorophyll is still in its infancy.

“Some studies suggest that chlorophyll supplements may help prevent cancer, treat iron deficiency anemia and clear up skin conditions like acne and sun damage,” says Catherine Karnatz, MPH, RD, creator of Nutrition Education RD in Rhode Island.

While all of that might sound amazing, these results come from studies done on animals, she says.

“That makes it difficult to translate to large human populations,” says Karnatz.

Relatively more research has been done on green foods, such as spirulina and other microalgaes. For example, a study of 30 people found that hemoglobin (the oxygen-carrying protein in red blood cells) increased over 12 weeks in people who took a tablet that contained 500 milligrams of spirulina. While these results are promising, especially for people with anemia, it’s important to note: This study lacked a control group.

Other research has linked spirulina with a reduced incidence of seasonal allergy symptoms, reduced cholesterol and triglycerides, appetite regulation and reduced inflammation.

Precautions

It’s a good idea to check with your healthcare pro before taking any new supplement—and that includes greens and chlorophyll supplements.

“This is especially important if you take any medications or have ongoing health concerns,” says Kim Yawitz, RD and gym owner in St. Louis, Missouri. “For example, many greens supplements contain large amounts of vitamin K, which can make prescription blood thinners less effective.”

Another precaution: Chlorophyll supplements can make you more sensitive to sunlight.

If you have celiac disease, know that some supplements contain trace amounts of gluten, a wheat protein, as a binder. As a result, you’ll want to look for products that have been certified gluten free by NSF or another outside organization.

Though not dangerous, some reviewers of chlorophyll supplements have mentioned that the supplements can lead to green stools, says Batayneh.

How to Choose the Best Chlorophyll Supplement for You

It's important to remember that supplements aren’t regulated by the FDA.

“This means that the nutritional quality of supplements may vary substantially between manufacturing companies,” says Karnatz.

As a result, you’ll want to do some due diligence to ensure what you buy contains what’s listed on the label, without any contaminants.

To do this detective work, look for supplements that have been:

• third-party tested for purity and potency by an outside organization like NSF, ConsumerLab, or USP.
• certified for using good manufacturing practices (GMP).
• certified by outside organizations that have tested to ensure the product is truly free of GMOs, gluten, pesticides, and other areas of concern. For example, the USDA stamp means the product is certified organic.

How We Chose the Best Chlorophyll Supplements

When choosing supplements for this review, we took several factors into account. At the top of our list: quality. Whenever possible, we try to include brands that submit their supplements for third-party testing and/or are certified by outside organizations for purity and quality. We also look for companies that are current Good Manufacturing Practice (cGMP) certified. That ensures the company uses FDA quality standards.

On top of that, we read what customers are saying about supplements, as well as look for products with high customer ratings. Because no one supplement works for all people, we also go to great lengths to include a variety of delivery methods, ranging from powders to tinctures to capsules.

Chlorophyll Supplement FAQs

How often should you use chlorophyll drops?

Each chlorophyll brand comes with a suggested dosage. That said, it’s best to consult your doctor to find the best frequency and amount for your specific needs.

Does chlorophyll burn fat?

Lots of companies and reviewers assume that chlorophyll supplements can help boost metabolism, but there’s little research to support that specific claim.

That said, the green plant substance might aid fat loss in a more indirect way: By reducing cravings for sweets. Though more research is needed, a small study published in Appetite of 38 women found that five daily grams of chlorophyll-containing plant membranes helped to boost levels of the appetite hormone GLP-1 (glucan-like peptide), thought to be important for decreasing cravings for sweets. While this is certainly promising, five grams (5,000 milligrams) is a lot of chlorophyll—roughly 50 times more than what’s available in most commercially available supplements.

Should you take chlorophyll drops in the morning or at night?

How much, how often and when you take your supplement will depend on many factors. It’s best to consult your health care provider as well as follow what the manufacturer recommends on your product.

Do doctors recommend chlorophyll?

Healthcare professionals will be quick to tell you to eat green produce as your first line of defense.

“Rather than taking a supplement, I’d prefer to see you eat more fruits and vegetables,” says Yawitz. “Unlike most greens supplements, fresh fruits and vegetables don’t have any additives or artificial ingredients. They typically contain more fiber, also, which is super important for overall health.”

That said, a greens or chlorophyll supplement can make sense for some people in certain situations, she says.

“Occasionally, I’ll recommend a greens supplement to clients struggling to get enough fruits and vegetables because of short-term challenges like travel,” Yawitz says.

Does chlorophyll stain teeth?

Chlorophyll is one of many substances (like coffee and tea) that can stain teeth. For this reason, you may want to brush your teeth after taking liquid chlorophyll supplements.

Takeaway: Are Chlorophyll Supplements Worth It?

Science, unfortunately, moves slowly.

As a result, it’s too early to tell whether chlorophyll supplements will live up to the hype. More well-controlled, randomized trials are needed to sort fact from fiction, as well as to determine the optimal dose.

In the meantime, there’s zero disagreement on the benefits of green produce. All dietitians that we consulted recommended aiming for at least five daily servings of fruits and veggies a day. Ideally, you’ll want to eat the rainbow—red, yellow, orange, purple and green—which will help you to take in a wide range of beneficial plant chemicals beyond just chlorophyll, the dietitians told us.

“A greens supplement won’t make up for a bad diet, but it could help fill any minor nutritional gaps if you eat pretty well and are generally healthy,” says Yawitz.
