You’ve seen the TikToks. People dropping neon-green liquid into tall glasses of water, claiming it cured their cystic acne, deleted their body odor, and basically turned them into a high-functioning plant. It looks cool. It’s vibrant. But honestly, most of the "wellness" world treats chlorophyll like it’s some magical elixir discovered yesterday in a secret rainforest.
It isn't.
Chlorophyll is just the pigment that helps plants eat sunlight through photosynthesis. We’ve known about it forever. But the sudden surge in interest has people asking: what are the benefits of chlorophyll, really? Is it actually doing anything for your blood, or are you just paying $30 for fancy, green-tinted pee?
Let’s get into the weeds.
Most of the "chlorophyll" you buy in a bottle isn't actually pure chlorophyll. It’s chlorophyllin. Pure chlorophyll is fat-soluble, meaning your body has a hard time absorbing it if you just mix it with water. Chlorophyllin is a semi-synthetic mixture of sodium copper salts derived from the real stuff. It’s water-soluble. This makes it easier for your gut to handle, but it also means the studies we have on the liquid version don't always perfectly match what happens when you eat a big bowl of spinach.
Understanding the Skin-Deep Benefits of Chlorophyll
One of the loudest claims on social media is that drinking green water clears up acne.
Science sort of agrees, but with a massive asterisk. Most of the promising research isn’t about drinking it; it’s about putting it on your face. A small pilot study published in the Journal of Drugs in Dermatology back in 2015 looked at people with acne and large pores. After using a topical chlorophyllin gel for three weeks, their skin actually showed significant improvement.
Why? It might be the "death by light" factor. Chlorophyll is a photosensitizer. When exposed to certain wavelengths of light, it produces reactive oxygen species that can kill bacteria. In a clinical setting, this is called photodynamic therapy. If you’re just sipping it while sitting in a dark office, you aren't exactly recreating those lab conditions.
That said, some people swear their "maskne" cleared up after they started the green water habit. It’s possible that the anti-inflammatory properties of chlorophyllin help dampen the redness. Or, quite frankly, people might just be drinking more water than they used to because they’re excited about their new supplement. Hydration is a hell of a drug.

The Internal Deodorant Myth?
If you go back to the 1940s and 50s, doctors were actually obsessed with chlorophyll as a way to control smells. They used it for colostomy bags and to help neutralize the scent of infected wounds.
Does it work for bad breath or sweaty gym pits?
It’s hit or miss. Some geriatric wards use it to reduce the odor of urinary or fecal incontinence in patients. A study in Life Sciences pointed out that chlorophyllin might help reduce trimethylamines, which are the compounds responsible for "fishy" body odors in people with specific metabolic conditions.
If you’re just a regular person who forgot deodorant, a dropper of chlorophyll might not be a "get out of jail free" card. But for some, it acts as a mild internal deodorizer. It’s not masking the scent with perfume; it’s theoretically binding to odor-causing compounds in the digestive tract before they can be released through your pores or breath.
What Are the Benefits of Chlorophyll for Blood Health?
This is where things get really interesting and a little bit weird.
Look at the molecular structure of chlorophyll. Now look at hemoglobin, the protein in your red blood cells that carries oxygen. They are almost identical. The only real difference? The "center" atom of chlorophyll is magnesium, while the center of hemoglobin is iron.
Because of this "twin" structure, there’s an old theory that chlorophyll can help with anemia or low energy.
- Hemoglobin Support: Some researchers have looked at whether chlorophyllin can help people with iron-deficiency anemia. There was a study involving patients with chronic kidney disease—who often struggle with low red blood cell counts—where chlorophyllin supplementation seemed to improve their markers.
- The Oxygen Factor: Better red blood cell function means better oxygen transport. This is why some athletes flirt with liquid chlorophyll to see if it gives them an aerobic edge.
Don't ditch your iron supplements if your doctor prescribed them, though. Chlorophyll isn't a direct replacement for iron. It’s more like a supportive assistant that might help the process along.

Cancer Prevention and the Aflatoxin Connection
This is probably the most "expert-level" benefit that doesn't get enough play on Instagram.
Chlorophyll might be a powerhouse at blocking certain carcinogens. Specifically, it’s been studied for its ability to bind to aflatoxins. These are nasty toxins produced by mold that sometimes grow on crops like corn or peanuts. They are known to cause liver cancer.
In parts of the world where aflatoxin exposure is high, researchers found that taking chlorophyllin at each meal significantly reduced the amount of DNA damage in the participants. It basically acts like a molecular sponge, soaking up the toxins in the gut so they get pooped out instead of being absorbed into the bloodstream and hitting the liver.
The Energy and Weight Loss Question
"I started drinking chlorophyll and now I have the energy of a thousand suns."
You've heard it. Is it real?
Maybe, but probably indirectly. If chlorophyll improves your red blood cell quality, you'll feel less sluggish. There’s also some evidence from animal studies suggesting that thylakoids (which are found in chlorophyll-rich plants) might suppress appetite by messing with "hunger hormones" like ghrelin.
A 2014 study in Appetite showed that women who took a green-plant membrane supplement once a day lost more weight than a control group. They also reported fewer cravings for sweets. So, if you're drinking your green water and suddenly don't want a Snickers bar at 3 PM, that might be the thylakoids doing their job.
Does it have side effects?
Usually, it's pretty safe. But let's be real: it can turn your poop green.

Don't panic if you see that in the morning. It can also cause some mild stomach cramping or diarrhea if you go too hard too fast. Also, because it's a photosensitizer, some people find they get a skin rash if they spend a lot of time in direct sunlight while taking high doses.
And if you’re pregnant or breastfeeding? There just isn't enough high-quality data. Stick to eating kale and spinach—they’re safer bets than a processed supplement.
The Practical Way to Get Your Green Fix
If you want to try it, don't feel like you have to buy the fancy glass bottles.
- Eat Your Greens: A cup of raw spinach has about 24mg of chlorophyll. Parsley is even denser, with about 19mg per half-cup. If you eat a massive salad, you're getting the chlorophyll plus fiber, Vitamin K, and Vitamin C.
- The Supplement Route: If you go for liquid, look for "Chlorophyllin Copper Complex." Start small. Maybe 5-10 drops in a glass of water.
- Timing: Taking it on an empty stomach might lead to better absorption, but some people find it easier on the digestion when taken with a meal.
Real Talk on the "Trend"
Social media loves a "quick fix."
Chlorophyll isn't going to fix a bad diet or a lack of sleep. It isn't a substitute for medical treatment. However, as a supplemental tool for skin health, potential detoxing of specific environmental toxins, and maybe a little boost in red blood cell efficiency, it has legs.
The biggest "secret" to the chlorophyll trend is that it gets people to pay attention to their internal health. If drinking green water makes you feel like a "wellness person," you’re probably more likely to make other healthy choices throughout the day. That psychological nudge is often more powerful than the molecule itself.
How to Start Using Chlorophyll Effectively
If you're ready to see if the hype is real for your own body, don't just dive into the deep end.
First, check with your doctor if you're on any medications, particularly blood thinners or meds that increase sun sensitivity (like certain antibiotics or acne creams). Chlorophyll can interact with those.
Second, pick your source. If you hate the taste of "grass," go for capsules. If you don't mind the earthy flavor, the liquid drops are more versatile. You can even add them to smoothies to hide the taste.
Finally, give it time. Most of the studies that showed results for skin or body odor took at least three to four weeks of consistent use. You won't wake up tomorrow with perfect skin just because you had one glass of green water before bed.
Your Actionable Checklist
- Buy a high-quality chlorophyllin supplement that is third-party tested for purity.
- Start with a half-dose for the first three days to make sure your stomach doesn't rebel.
- Increase your water intake. The supplement works best when you are well-hydrated.
- Track your results. Take a "before" photo of your skin and keep a quick note of your energy levels for 30 days.
- Don't ignore whole foods. Use the supplement as an add-on, not a replacement for eating actual vegetables.
