Activated Charcoal
Highly porous carbon used medically for poisoning and overdose. Popular for "detox" but daily use lacks evidence and may bind nutrients.
Bottom Line
Evidence-Based Take:
Activated charcoal is a legitimate medical intervention for acute poisoning and drug overdose. It works by binding toxins in the gut before they're absorbed. The problem is when people extrapolate this to "daily detox" use, where the evidence falls apart.
What the Evidence Shows:
- Strong evidence for acute poisoning (medical use, given within 1-2 hours)
- Some evidence for reducing gas and bloating
- Weak evidence for hangover prevention
- No evidence for "daily detox" or general health benefits
- Concern: binds medications, nutrients, and supplements
Honest Assessment:
Keep it in your medicine cabinet for emergencies, not your daily stack. The logic of "binds toxins" sounds good until you realize it also binds vitamins, minerals, and any medications you're taking. Your liver and kidneys already handle routine detoxification. Charcoal is for when those systems are overwhelmed by acute poisoning, not for everyday use.
Key concern: Taking charcoal regularly may cause nutrient deficiencies and reduce medication effectiveness.
Science
How Activated Charcoal Works:
Activated charcoal is carbon that's been treated to create millions of tiny pores, giving it an enormous surface area (up to 3,000 m² per gram). This surface adsorbs (binds to) other molecules through van der Waals forces.
Adsorption Process:
- Charcoal passes through the GI tract
- Toxins/drugs bind to charcoal's porous surface
- Bound substances pass through without being absorbed
- Eliminated in feces
What It Binds:
- Most drugs and medications
- Many plant toxins and chemicals
- Some heavy metals (limited)
- Vitamins and minerals (problematic for daily use)
- Supplements you're taking
What It Doesn't Bind Well:
- Alcohols (ethanol, methanol)
- Lithium
- Iron
- Acids and alkalis
- Cyanide
Medical Use:
In hospitals, activated charcoal is given within 1-2 hours of poisoning at doses of 50-100g. Effectiveness drops dramatically after this window. It's not useful for all poisonings.
Why "Daily Detox" Doesn't Work:
Your body continuously produces and eliminates metabolic waste through liver, kidneys, lungs, and skin. Charcoal in the gut can only bind substances in the GI tract, not toxins circulating in blood or stored in tissues.
Supporting Studies
7 peer-reviewed studies
View all studies & compare research →Practical Protocol
Emergency Use (Poisoning):
- 50-100g as single dose (medical setting)
- Must be given within 1-2 hours of ingestion
- Call poison control first
- Not for all poisonings (alcohols, acids, etc.)
Gas/Bloating (if using):
- 500-1000mg after meals
- Not daily, only as needed
- Take 2+ hours away from medications
If Using Occasionally:
- Take 2-3 hours away from all medications
- Take 2-3 hours away from supplements
- Take 2-3 hours away from meals (binds nutrients)
- Don't use daily
- Stay hydrated (can cause constipation)
Timing Matters:
| Situation | Timing |
|---|---|
| After medications | Wait 2-3 hours minimum |
| After supplements | Wait 2-3 hours minimum |
| After meals | Wait 1-2 hours |
| Before bed | Not ideal (binds overnight digestion) |
Forms:
- Capsules: Most common, 250-500mg each
- Powder: Messy but flexible dosing
- Tablets: Convenient but slower dissolution
Risks & Side Effects
Primary Concerns:
- Binds medications (can make them ineffective)
- Binds vitamins and minerals (deficiency risk with regular use)
- Constipation (especially without adequate water)
- Black stools (normal, not harmful)
Medication Interactions:
Activated charcoal can reduce absorption of: - Birth control pills - Antidepressants - Heart medications - Thyroid medications - Basically any oral medication
Nutrient Binding:
Regular use may reduce absorption of: - B vitamins - Vitamin C - Minerals (zinc, magnesium, iron) - Fat-soluble vitamins
Contraindications:
- GI obstruction or perforation
- Recent GI surgery
- Decreased consciousness (aspiration risk)
- Caustic substance ingestion (acids/alkalis)
Who Should Avoid:
- People on regular medications
- Those with nutrient deficiencies
- Pregnant/nursing (insufficient safety data)
- People with GI conditions
Risk Level: Low for occasional use; moderate concern for daily use
Who It's For
Legitimate Uses:
- Emergency poisoning (call poison control first)
- Occasional gas/bloating relief
- Food poisoning (within hours of ingestion)
May Consider:
- After suspected food contamination
- Occasional use for digestive upset
- Travel medicine kit (food poisoning backup)
Not Recommended For:
- Daily "detox" protocols
- Hangover prevention (doesn't bind alcohol well)
- General wellness
- Weight loss
- "Cleansing" regimens
Better Alternatives for Detox:
- Support liver function (NAC, milk thistle)
- Stay hydrated
- Eat fiber
- Sweat (sauna, exercise)
- Let your organs do their job
How to Track Results

What activated charcoal is and where it comes from
Michelle Broad explains that activated charcoal is a processed carbon powder typically made from coconut shells and nut husks. Its key property is trapping toxins in the body so they can be flushed out. Before becoming a beauty trend, it was used in trauma centers for drug overdoses and alcohol poisoning.
"best known to trap the toxins that are in your body so that they can be drawn out or flushed through other means in order for your body to stop absorbing them. So it's used to like, you know, to draw out impurities."
Teeth whitening with activated charcoal
Activated charcoal can balance pH in the mouth and absorb plaque that causes staining. Michelle recommends using a dedicated toothbrush since the charcoal stains everything, and shares her preference for Hello brand charcoal toothpaste combined with coconut oil.
"The main benefit to using this type of charcoal powder is that it can actually balance the pH level in your mouth. This not only helps to remove stains, but it can help the general overall oral health that you may be having."
Using charcoal for gas and bloating
Referencing the Journal of Gastroenterology, Michelle explains that activated charcoal capsules can help with gas and bloating. She emphasizes taking it before a gas-producing meal rather than after, and drinking plenty of water since the powder can become thick and clay-like inside the body.
"it is typically better that you take the product or the active in charcoal capsules before a meal or food that's going to produce the gas rather than trying to take them after you've eaten something that's going to cause gas."
Side effects and safety precautions
Michelle warns that activated charcoal binds not just toxins but also beneficial nutrients and medications. Daily ingestion can lead to malabsorption. Side effects include black stools, constipation from insufficient water intake, diarrhea, and vomiting at high doses. It should be avoided during pregnancy and breastfeeding without medical clearance.
"While it does stop toxins, it could also keep good nutrients from being absorbed in your body as well. Too much activated charcoal in your body could actually make you ill from malabsorption. So it's best to use it only when absolutely necessary."
What goes into the Universal Binder formula
Dr. Cabral lists the ingredients in his Universal Binder formula -- sodium bentonite clay, humic acid, apple pectin, carbonized activated charcoal from coconut hulls, and taurine -- as alternatives to zeolite for daily binding support.
"And you will see that it is sodium bentonite clay. We just talked about that in the last one. Humic acid, apple pectin, carbonized activated charcoal. So that is the healthiest, cleanest form coming from coconut holes. Taurine."
Is activated charcoal a trending pop culture "who"?
A stoned listener calls in to ask whether activated charcoal can be considered a pop culture "who" since it's suddenly in toothpaste, face peels, and drinks. The hosts compare it to Carly Rae Jepsen — people keep asking what the deal is, but it's actually useful.
"Anyways, who cares? No, no, no, no, no, no, no, no, no, no, no, so funny. You know what? I want her. I'll keep her. I want her. You can't have her back. She's out. move on i'm thinking of all the jesse j memes they're all good they're so funny they're so funny you know what i want her i'll keep her you can't have her back she's ours i changed my mind i love jesse j okay hey guys my name's andy um i'm sitting here with my roommate right now and we're obviously pretty baked i'm at like a four out of ten but whatever um We were looking through our Twitter feeds, and we keep getting these ads for this toothpaste that is like, it's activated charcoal, and apparently it whitens teeth, but the demonstration videos are horrifying. Like, it looks like people are brushing their teeth with black tar. And my question is, can a thing be a who? I know it's kind of meta, but, like, can activated charcoal, is that a who? Because I keep seeing it in, like, these, all these demonstration videos, whether it be the toothpaste or the activated charcoal face peels, or like now it's in drinks and shit. And I'm just like, activated charcoal is popping off. What an ingredient. All right. Well, good form, Bella Thorne. I will compare activated charcoal to, first of all, excellent call. Second of all, we love when people call in and they're very stoned. Obviously. It makes for perfect calls. I will compare activated charcoal to the likes of Carly Rae Jepsen or perhaps Tinashe. Because people are always like, wait, what's the deal with Activated Charcoal again? Why is it in everything? Why do people like it? I see people talk about Activated Charcoal all the time, but I don't know. But it's actually very talented and it's actually very useful. Here we go. Just like Emotion is a very good album and Flame is a very good single. Robbie, come clean. You use Activated Charcoal to paste. So Activated Charcoal is very good album and flame come clean you use activated charcoal to so activated charcoal is very good i'm i'm a little so okay activated charcoal is it's good for reducing odors i use it in my bathroom because that's where the litter box is and if i don't have an activated charcoal thing above the litter box and the odors get bad second thing about, it's like an antibacterial thing. So it's good for your gums when you brush. I use it every once in a while on my gums, but not necessarily for the whiting. The whiting thing, I'm sort of like iffy on because I haven't really noticed a difference. But the thing about activated charcoal that is crazy is, and one of the reasons I don't use it to brush all the time, is that it makes your mouth look crazy. It makes your mouth awful and it's a mess and like the black stains get all over your bathroom and you have to clean whenever you're um can i i have also a counter argument for this for the activated charcoal enthusiasm what um last week and us weekly here's the headline low bosworth shares her chic cinco de mayo activated charcoal margarita recipe this is taking it too far so the other this is what i was going to get into so like now the new trend is not just using it as some sort of like cleaning agent or antibacterial agent or whitening agent even though like as i get as i said before questionable now people are drinking it so it's like they put it in smoothies and it's like a detox agent which detox is sort of a scam to begin with um bosworth shares with us weekly it creates a margarita that is black in color and totally refreshing i mean it's just a margarita with charcoal in it it's truly a margarita with charcoal in it it's just a normal charcoal is that you're right. It started in like wellness communities where it became this like niche thing that like wellness, holistic wellness people use. So it's, you know, this is the same place that everything. Don't use chemicals. Use this thing that comes from the ground. Everything that Goop talks about. That's where this comes from. So literally it's moving up the ladder and then you have people who are like higher ups at like Unilever and places that make big brand beauty products. And they're thinking, what's the next thing that we can put on our labels to differentiate ourselves? And charcoal, somebody, you know, realized that charcoal was like a thing and that the idea that it would be black would be like a selling point and you think you were getting something extra then it broke through and now it is literally everywhere you are right yeah so it's it's everywhere and again yeah the fact that it's black and the fact that it's standing is seen as sort of a positive attribute by this people because it's like oh look if it's doing this thing if it's standing if it's like you can see it then it must be there is no reason though to be drinking a activated charcoal margarita on Cinco de Mayo like Lo Bosworth is truly the queen of taking it to the next level hi uh I need to talk about Joe and Mika Brzezinski and I know they're of news them, but I feel like a lot of people, especially if they're following celebrities, don't know who they are."
Charcoal toothpaste and odor control
One host reveals he uses activated charcoal near his cat's litter box for odor reduction and occasionally brushes with charcoal toothpaste, though he's skeptical about whitening claims and notes the messy black staining.
"Anyways, who cares? No, no, no, no, no, no, no, no, no, no, no, so funny. You know what? I want her. I'll keep her. I want her. You can't have her back. She's out. move on i'm thinking of all the jesse j memes they're all good they're so funny they're so funny you know what i want her i'll keep her you can't have her back she's ours i changed my mind i love jesse j okay hey guys my name's andy um i'm sitting here with my roommate right now and we're obviously pretty baked i'm at like a four out of ten but whatever um We were looking through our Twitter feeds, and we keep getting these ads for this toothpaste that is like, it's activated charcoal, and apparently it whitens teeth, but the demonstration videos are horrifying.

The charcoal detox drink trend goes too far
The hosts critique Lo Bosworth's activated charcoal margarita recipe and the trend of adding charcoal to smoothies as a "detox" agent. They trace how charcoal went from niche holistic wellness to big-brand beauty products because the black color became a marketing selling point.
"Because I've been, like, sensing their sexual tension since 2009, and I don't know when they first hooked up, because they were both married in a period of time, but, like, they're engaged, and it's weird, and now they're hosting the show together yeah good form Bella Thorne I mean what would you say Lindsay I mean I think we should have to we should come to I mean I don't watch Morning Joe my dad loves him he always says like Morning Joe said I don't care what Morning Joe said so just who is he he? He is the. I think they're who's. No, but who? They're the host. Joe Scarborough is the host of Morning Joe. He's a journalist. On what channel? On MSNBC. He's hosted the show Morning Joe with Mika Brzezinski since like 2007. Long time. Literally 10 years. Maybe 2009, but I think 2007. And they've always been the host. And when they started being hosts, they were both married to different people. And they have great chemistry as everyone always says. Well they have. Do they? It's weird. It's they sort of do. They have they're always fighting so it's it's more sexual tension because it's like because the fighting has always sort of been done in that playful way where it's like oh are they fucking off screen? Like they pretend to be like they pretend to be antagonistic and they pretend to have like these different it's just funny because it's a it's a kind of sexist thing to assume to be like to look watch them be like oh are they fucking and you're like oh that's rude like they're professional that i know we should respect their whatever but in 2013 when he got divorced from his wife literally then the rumors TMZ was like, something's happening. Something's up. So then Mika gets divorced from her husband. And they have since last year. So they have since claimed that nothing ever happened. They never acted on these feelings, which according to Mika and Joe, the feelings were there for a long time. For 10 years. But they never brought them up until after both of them had divorced their previous partners and so the but the moment that happened things were fast and furious they started dating um you know it was written about on page six immediately afterwards a year after they're engaged you know like they only took a she got divorced last year and only a year later year, they're engaged. So clearly, they've known each other for 10 years. This has been going on longer than just the time after she got a divorce to now. That doesn't make any sense. The main thing I wanted to say is that Morning Joe is, like, insufferable. It is so, it's one of those shows where, I mean, it's just like The View or The Reel or The Talk. Like, they pretend to be, you know, a know a more reputable and i guess they do get because they actually get politicians on the show like they get actual you know msnbc level talking heads where you you could have actual uh right political news breaking on the show it's that's a potential and he's well liked i guess in some respects but it's just a bunch of yapping where people are talking all over each other it's the morning the last thing you want is to be irritated because you're already irritated because it's the morning so it's very hard for me to watch it without like what i what i like about this is it kind of reveals the like going on because in this this daily beast piece that's just like how did they keep their relationship a secret there's this great part really do. Well, there's this secret from people outside of people who watch the show. So I had no idea that this, whatever this was happening. But this part, I really like this part because it shows the like, the wheelings and dealings of like how news is made. So it says in November 2013 short after Scarborough's divorce from his second wife was finalized and three years before Brzezinski's official split from her own spouse, the New York Post's Richard Johnson was preparing to declare them an item. According to sources familiar with the situation, Destrop Brzezinski reached out to then Fox News CEO Roger Ailes, like Johnson, a vassal in the Murdoch media empire, and tearfully asked Ailes, with whom she was friendly, to intervene with the gossip columnist, arguing that their respective children would be hurt by such publicity. Ailes made his pitch to Johnson on Brzezinski's behalf, and the columnist obligingly stood down. The next day, sources said Johnson was rewarded when Scarborough phoned him and gave him the juicy scoop that Alec Baldwin was about to be fired from his short-lived MSNBC program. So did you see what happened there? It's amazing. Literally. The quid pro quo there. Totally. So they were like, we will not, you know, reveal this relationship, but we will give you, like, a funny scoop that you will enjoy, and 100%, like, Alec Baldwin threw it under the bus. Yeah, good scoop. Also, Richard, I mean, that's like, that's such a, like, good classic Richard Johnson story, too. So, don't watch the show the show sucks they're they're gonna get married they're engaged did you read the story about how they were at mar-a-lago in january eating dinner with donald trump and donald trump uh i know jared kushner has is an ordained minister so jared kushner can like perform ceremonies and they revealed that they were engaged to Donald and Jared and stuff. And Jared was like, oh, I'll perform your... I'll marry you at your wedding, kind of as a joke. And then Donald Trump said, this is according to Joe and Mika. He was like, why would they have you do it when they could have the president do it? Like, I'll do it. I'll marry you guys. So wait, is he doing it? Noika are you gonna take trump up on his offer and she was like no no no i think like her quote is literally like six no's she's like that would be a bad idea no kidding no kidding mika anyway that's it for the. Anyway, that's it for the week. We've gone long. We've gone long. That was a good, there were some good calls. A lot to get through. We had a lot to get through. Good calls. Thank you, everyone, for calling in and letting your voice be heard this week on who's there. Yeah."
High fructose corn syrup directly linked to testosterone decline
The hosts discuss a study on males showing that high fructose corn syrup consumption is directly linked to testosterone decline, connecting processed food ingredients to the growing epidemic of hormonal dysfunction.
"It's a study that was done on males and basically showing that high fructose corn syrup is directly"
