What does chlorophyll do for the body?
Learn what chlorophyll does for the body, including how it can support weight loss, hormone regulation, skin health, and more.

We all remember learning about chlorophyll — the vibrant pigment that gives leaves their green color and allows plants to perform photosynthesis — in science class. It turns out that chlorophyll isn't just beneficial for plants — it also holds promise as a health supplement. Research on the effectiveness of chlorophyll in supporting human health is ongoing, and early studies suggest that the pigment may prevent weight gain, help balance hormones, support gut health, and even improve skin clarity. Here, we'll explore how chlorophyll may benefit the body — and how you can get more of it in your diet.
What is chlorophyll?
Chlorophyll is a natural pigment found in plants, algae, and even certain types of bacteria. It plays a key role in photosynthesis, allowing plants to transform UV light into chemical energy. There are two main types of chlorophyll, simply known as chlorophyll a and chlorophyll b, and both are vital for plant life.
Most chlorophyll health supplements are actually made with chlorophyllin, a chemical that's made from chlorophyll. Chlorophyllin maintains many of the natural benefits of chlorophyll, and is also thought to be more stable and more easily absorbed by the body. This chemical provides many of the same benefits as natural chlorophyll, but can also be easily consumed in the form of drops, capsules, or powders.
How chlorophyll may support healthy weight loss
A small 2014 study showed that chlorophyll supplements reduced hunger and increased the body's release of GLP-1, the hormone made famous by weight loss drugs like semaglutide (Ozempic/ Wegovy) and tirzepatide (Mounjaro/ Zepound). The study compared two groups of overweight women. The group that supplemented with chlorophyll felt less hungry, lost more weight, experienced fewer sugar cravings, and lowered their cholesterol levels more than the group that didn't supplement with chlorophyll.
While increasing natural chlorophyll intake or taking chlorophyll supplements isn't a magic bullet for weight loss on its own, early research shows that getting plenty of chlorophyll in the diet may both prevent weight gain and help to support healthy weight loss. Studies indicate that chlorophyll can help to regulate hormones like ghrelin, which can help to reduce appetite and cravings. This can make it easier to feel full, and may help people who are trying to lose weight feel less hungry while eating in a caloric deficit. Foods that are naturally high in chlorophyll (like green vegetables) tend to have high amounts of fiber, as well as a high water content, both of which can be helpful when trying to lose weight.
Chlorophyll has also shown promise in supporting healthy blood sugar levels, making it potentially a useful supplement for people who have diabetes as well as those who have insulin resistance. It's possible that this effect occurs because chlorophyll slows the absorption of carbohydrates in the gut. Many people experience an energy crash and an increased urge to overeat following a carb-heavy meal. Eating or supplementing with chlorophyll may help to prevent the blood sugar crash often associated with eating high amounts of carbohydrates.
The pigment also shows promise in supporting the body's natural detoxification processes, which can be helpful for those who are trying to lose weight. Some chlorophyll supplements claim that they support healthy energy levels, but this has yet to be backed up by research.
Chlorophyll for hormones
From mood to metabolism, our body's processes are governed by hormones. Chlorophyll may offer some indirect support for endocrine (hormone) system health.
Chlorophyll supports the liver as it works to remove toxins from the body. In addition to removing waste products and foreign substances, the liver also works to remove excess hormones from the body. Chlorophyll works to support the liver's natural processes, which may help to naturally balance hormone levels.
Many studies point to the natural anti-inflammatory effects of chlorophyll. The pigment shows promise in reducing inflammation, which is at the root of many hormone-related issues (like polycystic ovary syndrome), thyroid disorders, and insulin resistance. Chlorophyll's anti-inflammatory properties may help to calm the immune system and reduce oxidative stress on the body, supporting more stable endocrine system function.
Chlorophyll benefits for gut health
Chlorophyll is a prebiotic, meaning it works to provide food for the "good" bacteria in the gut. This can help to support healthy digestion, improve nutrient absorption, and support a healthy immune system. While more research is needed, early studies have shown that chlorophyll supplements may help to reduce the symptoms of inflammatory bowel disease (IBD).
Unlike some gut health supplements, chlorophyll is known for being especially gentle. One of the most well-known properties of chlorophyll is its ability to act as an internal deodorant in the digestive tract, which can work to prevent body odor and bad breath from the inside out.
How chlorophyll benefits skin
Research suggests that chlorophyll may be a powerful agent to support skin healing. Most of the studies used topical chlorophyll as opposed to ingested supplements to explore the effect of the pigment on skin. Small studies have shown that topical chlorophyll may help to reduce acne, reduce the effects of sun damage, and reduce visible signs of skin aging.
Chlorophyll's potential ability to support the body's natural detoxification processes may also support skin health. Support of these pathways may be especially helpful for people who are dealing with eczema, rosacea, acne, and other skin conditions that can be triggered by internal imbalances. To reap these benefits, you'll need to ingest chlorophyll or chlorophyllin, rather than just use a topical ointment.
How to get chlorophyll
If you're ready to start enjoying the benefits of chlorophyll, you have plenty of options. Clean eating — enjoying a diet that highly emphasizes unprocessed, whole foods — can be a smart way to start. Leafy greens, dark green vegetables, seaweed, spirulina, and wheatgrass are all rich in chlorophyll. Green grapes, broccoli, parsley, and green beans are also good sources of chlorophyll. Adding greens to fresh juice or a morning smoothie can be a delicious way to boost your chlorophyll intake.
To achieve therapeutic levels, however, you may need to use supplements. Chlorophyllin is widely available in liquid form, capsules, powders, and even gummies. Most people who use chlorophyll supplements use between 100 and 300 milligrams per day.
Side effects of chlorophyll supplements
As with any supplement, it's important to talk with your healthcare provider about whether chlorophyll supplementation is a good fit for your health. Talk with your doctor if you're pregnant or breastfeeding and curious about chlorophyll supplements. It's also important to talk with your doctor about whether chlorophyll supplementation is a good fit for you if you're taking antibiotics, acne medications, or antidepressants, as chlorophyll may interact with these drugs, potentially increasing your sensitivity to UV rays.

Evidation Health and BARDA Partner on Early Warning System for COVID-19
On June 4th, Evidation Health announced a new effort to develop an early warning algorithm to detect symptoms of COVID-19 and to understand susceptibility to infection, funded by the Biomedical Advanced Research and Development Authority (BARDA), part of the Office of the Assistant Secretary for Preparedness and Response at the U.S. Department of Health and Human Services (HHS) and the Bill & Melinda Gates Foundation.
Here at Evidation, we’ve been identifying opportunities to contribute to COVID research. THe Evidation app is a product of Evidation Health, and has a community of over 3 million and members all around the United States. With an engaged research population representing a variety of zip codes and demographics, we’re uniquely positioned to help researchers and organizations conduct meaningful research about the pandemic.
On June 4th, Evidation Health announced a new effort to develop an early warning algorithm to detect symptoms of COVID-19 and to understand susceptibility to infection, funded by the Biomedical Advanced Research and Development Authority (BARDA), part of the Office of the Assistant Secretary for Preparedness and Response at the U.S. Department of Health and Human Services (HHS) and the Bill & Melinda Gates Foundation.
“Many infected individuals are asymptomatic but still able to spread the virus, making efforts to prevent and slow transmission of COVID-19 difficult,” said Luca Foschini, Ph.D., Evidation’s co-founder and chief data scientist. “This initiative will use novel behavioral and physiological data to more effectively identify when and where people may contract COVID-19, and can potentially enable real-time interventions to limit spread and monitor outcomes.”
The analysis, performed in collaboration with non-profit 4YouandMe, will use de-identified data generated by self-reporting and wearable devices to track symptoms of COVID-19 in those at particularly high risk, including health care workers and other first responders, in order to better understand susceptibility to SARS-CoV-2 infection. One potential outcome of this work is an early warning algorithm to help individuals better understand and monitor their respiratory disease symptoms and take precautions against their spread.
“The ability to self-monitor and be informed of health status will empower Americans in their decisions to help slow the spread of this pandemic and improve health outcomes for people with COVID-19,” said BARDA Acting Director, Gary Disbrow, Ph.D. “This pilot study is not only an early step in demonstrating the utility of models developed using person-generated health data but also may provide data to better understand the varied symptoms of COVID-19.”
This program follows Evidation’s work with BARDA to monitor individuals for respiratory infections, such as influenza. Evidation’s existing research on influenza utilizes person-generated health data and population-based models with the goal of improving real-time respiratory infection monitoring at the individual and population level. BARDA is contributing a $720,000 award as part of BARDA’s COVID-19 Rapidly Deployable Capabilities program to identify and pilot near-term innovative solutions for COVID-19. Support from the Bill & Melinda Gates Foundation is from the $250 million the foundation has committed to address the COVID-19 pandemic.

How Evidation Members Rallied Together Through COVID Pulse Survey
Through this challenging time, we we've been inspired by our members who responded to many questions with great empathy and creativity as they have adapted to new routines
We’ve been continuing to monitor sentiment in the community around the coronavirus through an Evidation Survey called COVID Pulse. Since kicking off the survey on March 12th right after the coronavirus was declared a pandemic, we’ve been sending out a weekly survey to our members.
We wanted to quantify participation and interest and share some of the latest trends from our most recent surveys. After we released the first survey, we received over 120,000+ responses in five days from over 20,000 United States zip codes. The highest percentage of responses came from the age groups in the range of 30–39, followed by the 18–29 age range, and lastly, the 40–49 range. Though, we did see representation from members ages 18–80+! We’ve been pleasantly surprised by the number of members who have continued to check in week over week to share their sentiment surrounding coronavirus. In fact, 11% of survey respondents have completed all five COVID Pulse Surveys to date and 22%+ completed four out of five COVID Pulse Surveys.
Most recently, we saw that over 85% of respondents said that if social distancing and stay at home orders were lifted today, they would know what to do to reduce chances of contracting the coronavirus. We also saw that members would continue to take the necessary precautions even if social distancing guidelines and stay at home orders were lifted. Over 60% would continue to stay at home and maintain social distancing behaviors. Additionally, nearly 70% said they would continue to start to wear protective equipment (for example a face mask) in public settings. For those who responded in locations where shelter in place has been lifted, only ~25% of respondents said that they were attending small social events.
Through this challenging time, we were also inspired by our members who responded to many questions with great empathy and creativity as they have adapted to new routines. In fact, when asked about their concerns if they were to be diagnosed, 75% of respondents expressed concern over getting others sick in their worries. This fear was followed by 60% of respondents expressing their worry over the physical discomforts of getting sick. Regarding ways to minimize changes to physical and mental health, we’ve seen an uptick in individuals sharing the importance of maintaining whatever routines possible, avoiding or taking breaks from the news, and a continued connection through video chats with friends and family. In fact, maintaining connection through social media scored high for Evidation Members as a method to socialize with others. Both last week and this week, 70% of respondents said they used social media to socialize with other people.

Can a furry friend help you cope with COVID?
You may be wondering, can owning a dog help you live a bit healthier? It turns out that new dog owners in general are a promising sign of better health!
We know that the last few months have put everyone into a new funk. Work, lifestyles, and exercise are all uniquely different than they may have been back when 2020 started.
That’s why we decided to look at how Evidation Members were resting and perhaps coping with some of these changes. To better understand our community, we decided to look at members who logged fitbit data in 2019 and 2020 between January and April to see if the pandemic was causing people to change up their nap schedule (hopefully for the better). Total number of naps per user per day were counted and the average nap count per day was calculated across our Evidation population. See the figure below:
.jpeg)
It appears that members are indeed napping far more than they were in 2019, beginning at about the time shelter in place orders began (which was around March 15, 2020, see grey in graph). On average, after shelter in place began, Evidation Members napped 14.37% more compared to the previous year during this time period. That’s many more naps! And hopefully, people are using this time to rest and recuperate.
We know that being mindful of sleep is one way people can take care of their health. However, we also observed in the news that fostering dogs has been at an all time high. It has become so popular that there’s even a waitlist.
So, in addition to users napping far more compared to last year, we delved more into what other things users are doing differently during this uncertain time. We released a survey a few weeks ago asking our members about their dogs, what type of relationship they have with their pets, and their activity habits with their pets. We received over 35,000 responses!
The first thing we wanted to know about our members and their pets was whether they had recently fostered a dog. It turns out that many people have begun to foster dogs, likely due to the pandemic. In total, 1,500+ Achievers indicated that they fostered their dog in between February and April of this year. Compare that to only 450+ Achievers during that time period last year. It definitely appears that the pandemic is causing people to go out and lend a helping hand to a homeless dog.
Of the people who recently fostered a dog, 55% indicated that they are now working from home due to the coronavirus. 39% said that they are still going into work, and 5% indicated that they had worked at home prior to the pandemic. These newly remote workers appear to be helping keep these shelters empty.
You may be wondering, can owning a dog help you live a bit healthier? It turns out that new dog owners in general are a promising sign of better health! For those that got their dog in 2019 or 2020, we found that members walk on average about 350 steps more per day, comparing the 30 days prior to getting a dog with the 30 days post getting a dog. Even in pandemic times (though members are walking far less than their 2019 dog owner counterparts, by about 1000 steps per day for those that got their dogs in March and April), members with new dogs are getting a 200 step increase in steps pre vs post dog ownership! Of course, this is expected, and we’re happy to report that dogs can help you get more steps. This trend turned out to be especially true for the older folks in our population. The 50+ population increased their steps by about 500 steps on average, compared to the ~200 step increase for those who are less than 50. Take a look:
.jpeg)
Another interesting question we asked our members was whether or not they sleep with their pets and how often per week they sleep with their pets. While we didn’t see a necessary difference in sleep quality or total time when our members had their dog buddies snoozing with them, we did see many people report that they sleep next to their dogs. In fact, 73% of Evidation Members said they nap or sleep next to their dog, at least once per week. For members who said they nap or sleep next to their dog, over 19,000 reported to nap or sleep next to their dog at least 4 times a week! This may sound surprising for the folks who may not have furry pals, but many can attest that sleeping next to their dogs can be a comforting ritual.
The last thing we wanted to explore was whether we could learn anything about our members who had reported that having a dog had helped them manage with their health-condition (heart condition, limited mobility, etc). We found that 1000+ members agreed that having a dog helped. It seemed as though having a furry friend was very helpful for emotional support and well being. We did not find any concrete information around managing conditions, but were glad to hear that those who had self reported with many conditions (specifically anxiety, asthma, chronic pain, depression, diabetes, high cholesterol, hypertension and migraines) and who had a higher resting heart rate found having a pet to be supportive.
