The Truth About Activated Charcoal

read all about it

Hiya Gorgeous!

If you love learning about all of the latest nutrition fads as much as I do, you’ve probably noticed an interesting trend lately: Our food and personal care products are turning black!

So what’s giving ice cream, facial cleansers and even toothpaste a dark new hue? Activated charcoal!

Foods and products containing activated charcoal claim to help your body kill bacteria and rid itself of toxins. The cleansing and detoxifying qualities they boast make activated charcoal seem like it must have magical powers. But as with any other wellness trend that seems to suddenly to pick up steam, I had to wonder whether or not the products live up to those promises.

Since I thought you might be wondering the same thing, I did some digging. Now I’ve got all the deets on activated charcoal—ready to dive in?

What is activated charcoal?

Activated charcoal (aka activated carbon) isn’t just the stuff at the bottom of your grill pan. It’s made by burning coconut shells or wood, grinding them and combining the ash with an acid to activate it. The resulting paste is spread out on on a flat surface to dry, then bake. Sounds like something that you wouldn’t want in your body, right?

Well, this process gives charcoal a ton of surface area and a negative charge, which means it’s like a magnet, giving it the ability to attract and expel toxins from your system.

That’s why it’s been used since the 1800s as a highly effective remedy for poisonings and overdoses—it quickly binds to contaminants and prevents absorption.

Today, people are going crazy for activated charcoal for other reasons—let’s chat about what’s got everyone so excited!

What are the benefits of activated charcoal?

Detoxification

You may have considered or done a detox to reboot your energy, jumpstart your metabolism, drop some extra pounds or reset your relationship with food. Detox means a little something different to everyone, but it usually comes down to cleansing our bodies in some way. So, if that’s on your agenda, taking activated charcoal (along with a clean, plant-powered diet, extra hydration and self-care) can help you clear out the toxins that might be gumming up your system.

There’s very little scientific research out there about activated charcoal for detoxing, but integrative docs are generally on board with the idea and recommend taking it in capsule, power or paste form. Here are a two options from Solaray, a supplement brand I trust:

Keep in mind that taking charcoal internally may result in some side effects, so do your research and check in with your doc—I’ve also included a section below to cover some of the symptoms you might experience.

Digestive issues

Feelin’ tooty fruity? Tum troubles got ya down? When taken internally, activated charcoal may help neutralize liquids and gases that get trapped in the intestine and cause uncomfortable symptoms. Subjects in a study of its effectiveness against extreme gas, bloating and abdominal pain reported relief and none of the potential side effects commonly found with over-the-counter digestive aids.

Or, maybe diarrhea’s got you making frequent trips to the porcelain throne. This particular potty problem is often the result of bacterial infections or prescription drug intake—and activated charcoal may come in handy by helping your body get rid of bacteria and other toxins. Plus, there’s a bonus: Activated charcoal doesn’t come along with yucky side effects such as drowsiness, dizziness, constipation, fatigue and dry mouth that are common among antidiarrheal medications.

Most docs recommend taking activated charcoal at least 30 minutes before each meal, and some also discourage supplementation for more than 3 consecutive days. So, as always, consult with your doc to find the form and dosage that’s best for you!

Oral health and teeth whitening

I bet that black toothpaste is one of the last things you ever thought you’d see—I know I was surprised the first time I spotted it! Well, it turns out that activated charcoal may help strengthen enamel, whiten teeth and improve gum health by binding to and eliminating bacteria and toxins. So, if you’re interested in taking your oral health up a notch, you may want to check out one of the many products now available with activated charcoal (I’ve included a few options below).

While a couple of studies indicate that products containing activated charcoal boost oral health, there’s a lot more anecdotal evidence than true research at this point. Most integrative docs say there’s very little risk in trying one of these products, but some dentists recommend only weekly or monthly use for people with especially weak enamel. As always, I encourage you to check with your dentist before you give charcoal toothpaste a try!

I haven’t had a chance to try any charcoal-infused oral care products yet, here are a few promising options (all vegan and free of gross additives!):

Wound healing and skin cleansing

With its antibacterial effects, activated charcoal can bind to harmful particles in wounds and speed up the healing process. It can also remove toxins and fluids that slow down healing, even helping to heal burns and skin ulcers. And because bacteria in wounds often creates an odor, charcoal dressings are being used effectively for their ability promote healing and reduce the yucky aroma.

You can also find charcoal-rich salves and infused oils to treat your scrapes, cuts, burns and boo-boos of all kinds.

Wounds and infections aside, your skin is an organ that constantly absorbs toxins, pollutants and other undesirables. Activated charcoal is great for day-to-day use because it can bind to those nasty skin‑truders and prevent them from wreaking havoc on your fabulous epidermis. You’ve probably seen moisturizers, cleansers, night creams and face masks containing activated charcoal pop up—maybe you even tried one (if so, I want to hear about it in the comments!).

Here are a few options from brands I like (all vegan, of course!):

Kidney disease

Activated charcoal attracts and releases toxins and waste in urea (the main component of urine), which can save poorly functioning kidneys from having to excrete them.

One study showed that activated charcoal (taken orally in combination with a low-protein diet) can help treat elderly patients with end stage renal disease—even allowing them to avoid dialysis. More research is necessary to prove the efficacy of activated charcoal for kidney disease, but I’ve gotta say that I’m pretty excited about the prospect!

Dosage and possible side effects

Activated charcoal comes in so many different forms… gels, pastes, powders, capsules, drinks, mouth rinses, moisturizers, creams, masks and soaps. Topical products don’t come along with a whole lot of risk in terms of dosage—just follow the instructions on the packaging and be sure to test in a small area, especially if you tend to have sensitive skin (this goes for any new product you try!).

As for taking it internally, recommended doses haven’t been set by the National Institutes of Health Office of Dietary Supplements. Like I said earlier, some brands recommend against taking it on long-term basis or even for more than 3 consecutive days. That’s why I encourage you to check with your doc first—it’s your best bet for making sure you’re adding activated charcoal to your routine in a safe and effective way.

Side effects of taking activated charcoal internally are mostly harmless and more common if taken for a long period of time, in higher doses or in sensitive individuals. But, they are important to be aware of and include:

  • Black stools
  • Constipation
  • Diarrhea
  • Vomiting

Activated charcoal in foods, toothpaste or other oral products may result in a black tongue or black teeth. This is really only a problem if you’re on a date or at an interview!

Here’s one more thing to keep in mind: The same thing that makes activated charcoal so effective is also what makes it potentially dangerous. It can bind to and reduce the potency of certain prescription medications. The same goes for vitamin and mineral supplements.

The bottom line on activated charcoal

Well, here’s the truth—there is no bottom line… yet. A whole lot more research and testing has to happen for me to say definitively what I think about activated charcoal. But, any natural remedy that comes along with this many potential benefits gets me pretty excited. What we’ve learned so far is incredibly promising, and I can’t wait to see what’s next!

Important note:

Sorry about the fluoride dust up everyone! We’re eliminating our note about fluoride in activated charcoal toothpaste as it is obviously a major concern. My research team and I shouldn’t have made a definitive statement without backing it up with support articles. We will definitely do a deep dive on this issue for a future blog! For the longest time I have not been an advocate of fluoride, but our recent research opened the door to questioning my understanding.

Here’s some of the information we’re looking at:

But this is by no means an exhaustive dive on this important issue and therefore shouldn’t have been treated casually. Thanks for your concern and push back, it keeps me on my toes! Also, if you have credible studies you want to share, please share them here. We’re all in this together.

Peace & black ice cream,

    There are many benefits of using charcoal but we need to know first what the product is. Nowadays people are incorporating it in their daily usage massively. You will get this carbon form in the natural and raw form but when you are planning to incorporate something into daily care you need to make sure that you incorporate the best product that will suitable for you. In that case, you need to know that raw carbon is not suitable for everyone so you need to get a product that is chemically treated and not that harsh. I have used charcoal a lot and thanks kamil siwarga wood ltd selling good quality of Activated charcoal.

    I have been flouride free since 2012. I have been seeing the same dentist since 2006. I moved recently and had to get a new dentist. They have found 10 cavaties. I am more than disappointed in my old dentist and now wondering if I had been using flouride would this have happened? I oil pull every morning and floss daily. I don’t eat sugar, caffeine, gluten, or dairy. We filter all of our water. If you spit the flouride out and rinse well is it still harmful.

  7. Elke says:

    Have you ever considered publishing an ebook or guest authoring on other websites?

    I have a blog based on the same subjects you discuss and would really
    like to have you share some stories/information. I know my audience would appreciate your work.

    If you’re even remotely interested, feel free to
    send me an email.

  8. Nina says:

    Hi Kris, thank you for this article! I have been wondering about this and I am glad your research came to me through your newsletter.
    I’ve also been wondering about fluoride and I’m happy to see the comments about that and how you handle it. I still trust you as a source! As you wrote, we’re in this together. 🙂

  9. Mary W says:

    Great info! Schmidt’s also makes an activated charcoal toothpaste with a mint flavor. Tastes & works great 🙂

  10. Tam says:

    I use MyMagic Mud brand toothpaste and bamboo toothbrush.
    I’ve gone through my first tube and my teeth are MUCH whiter and mouth is cleaner.
    I went in as a sceptic! I’m so impressed. I can’t chemical whiten at the dentist so magic muds toothpaste … I’m greatful I found it. FYI

  11. Rayanne says:

    Hi everyone…may we all walk in Peace and pluck out our own log in our eye before throwing Kris under the bus. Hasn’t our divine God forgiven each and every one of us billions of times when we’ve slipped up and who stands with us daily in the arena supporting us with love and compassion? We are not all perfect…we are just doing our best in every moment. Thank God my friends have stood by me through thick or thin cause it would sure be a lonely life if they hadn’t. I’m standing by you in the arena, Kris. I love you.

  12. louise says:

    Not interested in charcoal at the moment…Irene

  13. brian says:

    The dangers of FLUORIDE are well known in the natural community, this is no conspiracy theory there are a tremendous amount of studies to back this up, its toxic to all body systems, thyroid, brain, cancers, and calcifies the penal gland, our connection to the Universe! There is no debate on whether synthetic sodium fluoride is healthy, the only issue is that that we cant wake people up fast enough to the criminal deception!

  14. K says:

    I’ve also used charcoal intermittently for gut issues when I think I’ve caught a bug from travel or food – one capsule tends to be all I need to set things right. It’s been so much better than things like immodium and pepto bismol.

  15. Susan says:

    Thanks for the info. My mom gave us activated charcoal capsules for upset stomach or if we thought we had food poisoning.

  16. Pamela Joy says:

    I think activated charcoal is great for tummy issues. But one time, I overdosed on fried green tomatoes (I love them so much!) and felt like I was gonna barf (or wished I would, and get it over with). I never wanted to eat again – especially not fried green toms. I remembered charcoal, and took one or two capsules. I instantly started to feel WORSE! More nauseous and miserable than I was. I don’t know if it concentrated all the grease together, or what. But it was awful. So I am not sure it’s a great idea for tummy aches from greasy foods. Did I eat more fried toms the next day? Hell yeah. Just not as many..

    • Jen Reilly, RD says:

      Hi Pamela! I’m the nutrition director here (and also a lover of fried green tomatoes!) so I’ll chime in for Kris. I wonder if your experience would’ve been different had you taken the charcoal before the tomatoes? While it seems to work for excess bloating and overdosing on meds, I’m not sure about it’s potential in this type of food overload. Lesson learned and glad to hear your experience didn’t dissuade you from enjoying fried green tomatoes the next day 🙂 xo! – Jen

    I thought the charcoal toothpaste sounded promising, so I clicked on your link to it. Amazon’s reviews include one by a purchaser who at first gave this toothpaste a 5 star rating, then later came back with a one star rating and said their teeth has started cracking. Are you familiar with this side effect? the reviewer said they researched it online and found others with the same issue.

    • Jen Reilly, RD says:

      Hi Donna! I’m the nutrition director here so I’ll chime in for Kris. While the general consensus among dentists is that activated charcoal toothpaste doesn’t have any side effects (except a messy sink!), all the products recommend checking with your healthcare professional before use. Some dentists warn that activated charcoal toothpaste can be abrasive (although the product we linked to is non-abrasive) and should only be used once a month for people with especially weak enamel. I’d recommend checking with your dentist first as he or she knows your teeth best. Hope that helps! xo – Jen

  18. kris says:

    Hi Marie-France – thank you for sharing that link, I’ll take a look. I’ve added some clarification at the end of the post about this issue, so I hope you’ll check that out. Please know that I appreciate your concern and your willingness to speak up. xo

    • Marie-France says:

      You are so gracious Kris and I love all you do. Some slip ups happen to the best of us and you are recovering really well. Thank you for all you do. Another book that is talking in-depth on mercury amalgams and fluoride is a mouthful of poison. The author, Dr. Wentz, cites all his research and scientific work. An important read.

  19. Georgia Grey says:

    I’ve been taking activated charcoal consistently for a couple months…I’ve found it’s dramatically helped my symptoms from Lyme Disease. I feel the best I have in a while!

    • kris says:

      Wow, Georgia! Thank you for sharing that – this is another use for activated charcoal that I hope we can all learn more about. I’m so glad you’re feeling better. Mwah!

  20. Guy Richer says:

    There is a very interesting book on this subject, if you can read french. It is called: “Mon petit docteur” from the author Danièle Starenkyj published by “Publications Orion Inc.”. Beside, I tried to find information about how to activate charcoal. When Kris Carr says it’s by combining it with “an” acid, it worries me. What acid? But I found elsewhere there are other ways and I would appreciate if somebody could explain how to produce home made activated charcoal. It’s a simple product that should not cost a lot. But they keep the secret.

  21. Karen says:

    Fluoride???? I thought this article was good until I got to the fluoride part! Omg…fluoride is a neurotoxin!! Not sure why you’d be promoting an industrial waste biproduct?!

    • kris says:

      Hi Karen – I hear you. I’m sorry we made such a definitive statement without more clarity and research to back it up. I added some more info about this at the bottom of the post. I hope you’ll check it out. Sending love.

  22. Sadie Elliott says:

    I have taken charcoal tablets for years when I have a bad stomach. It stops any diarrhea and gas pretty quickly. Depending on how bad it is, I might take one, two or three capsules. Or if I’ve eaten a spicy meal, I take one right after,although I might try the ‘before’ idea, I too recommend it to people who’s tummy’s are upset. It works for me (Although I haven’t tried the toothpaste, it makes sense).

  23. Paul says:

    Scientism is alive and well it seems. We have better resources than this Kris. Products like Charcoal and bentonite, these should NOT be used haphazardly, without purpose / functional intent. Dig deeper, plz! Dr. Jerry Curatola would be a great resource. No offense to Nadine, but current cutting edge of oral microbiome health has surpassed that of Artemis. These are products to break things down, bandaids.. they do not help rebuild / support microbiome. But Woah, Flouride? Com’mon now.. Not cool 🙁

    • Caitriona McGlynn says:

      I completely agree, Paul…

    • kris says:

      Hi Paul – thank your for your comment. I hear you, and I’ve added some clarification about fluoride at the bottom of the post. I hope you’ll check it out.

      As for activated charcoal and any other supplement, I couldn’t agree more – it’s so important to work with your doctor if you’re thinking about adding it to your routine.

      Again, thank you for taking the time to share your thoughts. xo

  24. Sandra Letenzi says:

    Kris, I’m a huge fan of yours, but I have to say I was pretty shocked and disappointed to see the paragraph on fluoride in this article. I think it’s pretty widely known these days that it’s classified as a neurotoxin and absolutely not essential for oral health. Aside from that, great article, activated charcoal is a staple in my routine.

    • kris says:

      Sandra – I’m sorry you were disappointed, I completely understand. I added some clarification at the bottom of the article, so I hope you’ll check that out. Thank you for sharing your thoughts and for being here – sending love.

  25. Rebecca says:

    Wow about the fluoride…. Disappointed to see that footnote on fluoride describing it as “essential for oral health”. As someone who promotes alternative health care, (even when you frequently admit that there’s yet very little evidence that some practices/products are actually effective), I’m amazed that you would advocate for something that is not accepted by most alternative health care followers/advocates. As always, people need to do research from multiple sources, and make their own decisions. I appreciate your efforts, always have. That said, I think a Kris Carr article on fluoride would be helpful, if only to clarify your position on what many of us consider to be little better than poison. Just sayin’.

    • kris says:

      Hi Rebecca. Thanks for your thoughtful comment. You’re right – the statement on fluoride didn’t address all of the complexities that we need to consider. I’ve added some clarification about it at the end of the post, so I hope you’ll give that a read. I appreciate you and I’m sending lots of love. xo

  26. Sally Scobey says:

    I tried activated charcoal toothpaste, and I’ll admit, it was a little unnerving at first. All that black in and around my mouth. Some got on my towels, but washed off, thank heaven. I do feel I have a cleaner mouth overall, but am just finishing my first tube. I bought two. By the way, you have shown that you want to look carefully into issues, and your activated charcoal blog indicates that. But you need to look further into fluoride before you endorse it. It is more than highly controversial. I am avoiding it for many reasons, including thyroid.

    • kris says:

      I hear you, Sally. We shouldn’t have made such a definitive statement without the research to back it up. I hope you’ll check out the additional information I added about this at the bottom of the post. Thank you for speaking up – your input means a lot to me. xo

  27. Laura says:

    Hi Kris,

    I have used activated charcoal whenever I have any stomach issues, bloating etc.. whenever i travel it is in my first aid kit. It works I usually only need one capsule! My dentist always gives me one before and after removing any mercury fillings.
    I agree with everyone else on fluoride not being good so I was quite surprised that you are ok with that.

    • kris says:

      Hi Laura – glad you’ve had luck with activated charcoal. I hear you on the fluoride issue. I’ve added some additional information about this at the end of the post. I hope you’ll read it and thank you so much for sharing your thoughts.

  28. Sq says:

    Kris, I have been following you since my bout with breast cancer in 2007-2008 after watching Crazy Sexy Cancer. You are my go to everyday, but this is a bit discouraging as to how with all your resources and knowledge you could even think that fluoride was good or even necessary for oral health. I think you need to check into it a bit more.. All the vegan doctors and sites I refer to as well say it needs to be banned, taken off the market. I have been using Desert Essence tea tree among others with no fluoride. Thank you for all you do for us out here but you need to verify all facts.

    • kris says:

      Hi there, thanks for your comment. You’re right – research is critical, and we shouldn’t have made such a definitive statement without it. I’ve added some additional information about this at the bottom of the post, so I hope you’ll give it a read. I love Desert Essence, so I’ll be sure to check out their toothpaste – thank you for the recommendation. xo

  29. Rhonda says:

    Please please reconsider the fluoride. There are several brands of non-fluoride toothpaste with activated charcoal. Our family likes the Claybrite brand.

    • kris says:

      I hear you Rhonda – I’ve added some additional info about this at the end of the post. Thanks for the brand recommendation, I’ll check that out. xo

  30. Debbie says:

    I agree on the fluoride comments. I was totally shocked when I read that. I did my own research awhile ago, and based on what I found, I would never use fluoride. I can’t believe you’re telling people it’s “essential for oral health.” I respected and trusted you and the information you share. Now I’m not sure what to think about other information you’re sending out into the world.

    • kris says:

      Hi Debbie – we shouldn’t have made such a definitive statement without research to back it up. I’ve added some additional clarification to the bottom of the post. I hope you’ll check that out, and thank you for sharing your concern. I hear you and please know that your trust means a lot to me. xo

      • Debbie says:

        Thank you for listening and making changes to your article. Your understanding, concern, humility, and open-mindedness are remarkable.

  31. Josh says:

    Thanks Kris! Great tips as always 🙂 I have gut and skin problems, so I’ll give this a go and let you know the results. Have a brilliant day, love Josh x

    • kris says:

      Glad you’re thinking about giving this a try, Josh! Remember to check in with your doc, esp. if you’re treating those challenges with other meds/supplements. xo!

  32. I feed my pigeons activated charcoal. They sell it at the feed store, as a supplement for birds.

  33. Caitriona McGlynn says:

    This article was 10/10 until I read the paragraph on fluoride, which you say is necessary for oral health. Please do your research on that. Fluoride is a neurotoxin. You’ve lost all credibility for me. Unsubscribing.

    • DP says:

      Same here. I couldn’t believe you allowed for this to be on your site, Kris. Fluoride????? I know other people wrote it for you but you lost your credibility for me too.

      • kris says:

        I hear you – we shouldn’t have made such a definitive statement without more clarity and supporting research. I’ve added some clarification at the end of the post above. Thank you for sharing your concern. xo

    • Jennifer says:

      Thank you Caitriona McGlynn. That’s exactly what I was gonna say. I stopped using fluoride several years ago after doing some home work. It’s scary stuff and most people already get some in their water. I was shocked when I saw that in the article!

      • kris says:

        Hi Jennifer. I appreciate you voicing your concern about this. I added a note above (at the end of the post) to expand on the subject. Sending love.

    • Yikes. I still think you’re a wonderful person with a great message about taking personal responsibility for your health and well being. That said, the fluoride thing threw me for a loop, too. Fluoride is actually detrimental for thyroid issues, among other problems. I haven’t used it for many years – and I’ve never had a cavity. I do oil-pulling with essential oils proven as anti-bacterial, and I brush with both activated charcoal and homemade, non-fluoride toothpaste. While I will continue to recommend your recipes, I won’t be recommending this site as a health resource.

      • kris says:

        Hi Michelle, I hear your concern. It was a definitive statement without all of the appropriate research to back it up. Please see the note I’ve added at the bottom of the post about this, and thank you for speaking up. xo

        • Caitriona McGlynn says:

          Kris,
          Your inserted research links do neither “clarify” nor “back up” your previous statements re: fluoride.
          Thanks

          • kris says:

            Hey Caitriona! The update I posted was not intended to back up anything, but to acknowledge that we shouldn’t have made a definitive statement without the research to support it. By “clarify,” I mean clarifying that we can’t possibly cover a topic like this in a few simple sentences, and trying to address it as a side note wasn’t the best way to go. This is a complex issue that warrants its own post. Please don’t conflate my response to the concerns raised in the comments with a complete exploration of this subject. The links that I included in my note are just the beginning of that research. Thanks!

    • Ruth says:

      Has the fluoride reference been removed…or did I miss it?

      • kris says:

        Hi Ruth – we took out the reference because it didn’t properly address the complexity of this issue. I’ve added a note at the bottom of the post about this, so you can find some information there. xo

    • kris says:

      Hi Caitriona – I hear you. Thank you for sharing your concern. I’ve added a note about this issue to the end of the blog post. xo
