Natural deodorant has gotten really popular in recent years, but a lot of people have mixed results. This probiotic deodorant recipe doesn’t just mask the odor, it attacks it at the source!

One of the most asked questions on my popular homemade deodorant post is: “Can I put this in a plastic deodorant container for easy application?”

And the answer is- absolutely yes! But it will work better if you make a couple of tweaks! I’ve played with my original recipes to create several different variations, including this probiotic deodorant.

Why Do Armpits Stink?

Before we go into fixing the problem, it helps to know why it’s there in the first place. Conventional deodorants work by covering up body odor with fragrances. They also clog pores with aluminum to prevent sweating. But why do we get stinky to begin with?

B.O. 101

Like the rest of our skin, underarms have a natural microbiome complete with bacteria. When things are unbalanced and the bad bacteria is in charge it causes stanky pits. This odor-causing bacteria, not sweat itself, is to blame. According to Popular Science:

“Sweat by itself doesn’t actually smell. It contains long chains of molecules that are too heavy to vaporize and reach your nostrils. But the bacteria in your pits break down these big molecules into smaller molecules that fly off, and depending on what kind of bacteria are living on you, those volatiles can smell pretty foul.”

What we eat plays a big role in our underarm bacteria, as do healthy (or unhealthy) lifestyle choices. Genetics can also play a part. Our bodies detox through the sweat in our armpits. If there are more toxins released into our system, then naturally there’s more stinky sweat.

Want to Buy it?

I should confess that sometimes I don’t make my own deodorant anymore. The company I co-founded, Wellnesse, now offers a mineral deodorant. Check it out if you aren’t into the DIY version or don’t have the ingredients on hand.

It’s cruelty-free, phthalate and paraben free, and of course aluminum-free. It also features soothing ingredients like aloe, and cocos nucifera (coconut oil), without harsh preservatives.

Why Natural Deodorant Doesn’t Work

Many people who make the switch to natural deodorant are disappointed with the results at first. They may notice an increase in underarm wetness or even smell. Then there’s the infamous baking soda rash. But what’s really going on here?

If our skin is used to having blocked pores preventing it from sweating, then there’s a backlog of toxins. That area is also rich in lymphatic tissue which helps us eliminate waste products. Using natural deodorant helps to support these natural processes, but it takes time to balance things out.

Start with a Detox

If you’re new to natural deodorant, I’ve found an armpit detox, done once a week or so, greatly speeds up the adjustment period. It also makes the deodorant more effective more quickly. Here’s how to detox your pits.

Since switching to a natural deodorant I’ve gradually noticed less underarm odor and sweating.

Probiotic Deodorant Bar

That said, how can probiotics help us have healthier (less stinky!) pits? Probiotic deodorant works by adding more of the good bacteria to the skin microbiome. Over time this helps push out more of the bad bacteria strains that cause odor.

Some of the healthy bacterial strains found in armpits include Staphylococcus epidermidis and Propionibacterium acnes. Outside of test tubes meant for a lab, these strains are harder to source. Instead, most probiotic deodorants rely on strains normally found in the human gut, like lactobacillus supplements. While they’re still beneficial for skin, the effects may be more transient.

These nourishing probiotic deodorant bars are slightly thicker than my original homemade deodorant recipe in a jar. It also uses many of the same ingredients as my lotion bars and sunscreen bars. You can order the ingredients in bulk and save a lot of money on your family’s skincare products this way.

If you have sensitive skin or struggle with odor, this can be a great option! I did include some baking soda to help control odor. If you’re very sensitive you can replace it with more arrowroot for a baking soda free version.

Choose Your Scent

Essential oils naturally have antimicrobial properties that make them great for homemade deodorant. My favorite here are lavender, frankincenses and citrus essential oils. Here are a few more skin-safe options. You can also do an unscented version if desired.

Try making your own deodorant if you haven’t already. You’ll not only save money and avoid synthetic chemicals, but I’ve found the homemade versions work better too!

Probiotic Deodorant Recipe

This simple recipe helps fight underarm odor naturally, with healthy probiotics!
Prep Time5 minutes
Active Time30 minutes
Cooling Time8 hours
Total Time8 hours 35 minutes
Yield: 5 deodorant tubes
Author: Katie Wells

Materials

Instructions

  • Combine coconut oil, shea (or other) butter, and beeswax in a double boiler, or a glass bowl over a smaller saucepan with 1 inch of water in it. Combine in a quart size glass mason jar with a lid instead and place this in a small saucepan of water until melted. This will save your bowl and you can just designate this jar for these types of projects and not even need to wash it out…
  • Turn the burner on and bring the water to a low boil. Stir ingredients occasionally until they're melted and smooth.
  • Remove from heat and add the vitamin E oil, baking soda, arrowroot powder, probiotics, and essential oils. Make sure the mixture is not hot to the touch (warm is ok) so that the heat doesn’t kill the probiotics. If you're using the brand I've linked above, they're fine at higher temperatures.
  • Gently stir by hand until all ingredients are incorporated.
  • Let cool for about 15 minutes, until the mixture is slightly thickened, but still a pourable consistency.
  • Pour the deodorant mixture into new or repurposed and cleaned deodorant containers. Let dry overnight to fully harden.

Notes

  • This recipe can be adjusted to make any quantity that you’d like by increasing the amount of ingredients used.
  • Shea butter yields a softer deodorant consistency, while cocoa butter is much firmer. You can also use a blend of shea butter, mango butter, and/or cocoa butter.  

Deodorant FAQs

Why is mine taking so long to harden?

This is common when using the baking soda. Try putting it in the fridge for a few hours to harden. I actually like keeping mine in the fridge all the time and applying it while I’m making breakfast since it keeps it really cool and refreshing.

It seems to be leaving stains on my shirt- what do I do?

This is likely due to the oil residue that’s there for a few minutes right after applying. Try keeping it in the fridge so a smaller amount is transferred to the skin. Or wait about 5 minutes after applying before putting a shirt on.

Help! I have a horrible rash after a few days/weeks/months of using this.

This is common in some skin types and if you’ve used conventional deodorant for a long time. I’ve found that doing an armpit detox once a week makes a huge difference. You can also try omitting the baking soda from the recipe. This resolves the issue for most people.

Is this an antiperspirant?

No. Stopping the body’s ability to sweat is not a natural process. There’s no way I know of to do this naturally. The good news is that you’ll sweat less as your body adjusts to a natural deodorant and it won’t be needed anymore. Again, the armpit detox can help speed that up. I went from using clinical strength deodorant to not needing an antiperspirant at all!

I’m allergic to coconut oil

If you have a coconut allergy then you can use 2 Tablespoons of a liquid oil instead of the 1/4 cup of coconut oil. Olive oil, grapeseed, and sweet almond oil are several different options.

    Many people seem to be having a reaction to the baking soda, so I was wondering what is the purpose of the baking soda? Obviously it is your preferred ingredient compared to corn or tapioca starch.

    I’m curious why you omitted the zinc oxide? It has great antimicrobial properties. I’ve been using diaper cream under my arms with great results, but looking to make my own bar based on this recipe. I’ll definitely be using zinc oxide though.

    Are there any tricks to removing the finished product [deodorant bars] from a silicone mold? Haven’t tried making these yet and I just want to prepare myself. 🙂

    Hi. I like this so much. By the way, can i use olive oil instead of coconut oil with any of your recipe?

    For desert dwellers like me or anyone who wants a bar that is not as pasty, try using raw kokum butter. In the summer months I use all kokum butter and only half kokum and half shea or mango for the winter batches. It protects skin and has a great non-pasty smoothness. Raw kokum butter comes in hard dry lumps but melts into the coconut oil perfectly and makes a bar that outdoes commercial bars in texture and provides much better staying power. Better on you and not on your clothes. I did have to use a summer batch recently (in the cold) and it was very hard – a little dab of witch hazel on the skin allowed it to spread well. So if you make it too hard for your liking remember you can always remelt and add a wee more coconut oil to soften the bar or just moisten skin with witch hazel first.
    **oh and I found a great life hack. If you break the cap on one of your “go toobs”, remove all the hard plastic and keep the silicone part. If you fill that silicone (no more hard plastic) with this home deodorant (set in a cup to fill & harden) you can squeeze it up, apply and it goes back in for storage. I use a locking french barrette clip to close the end for travel. No more messy deo muffins.

    I was looking at both the deodorant and the deodorant bar recipe and wondered the purpose for the probiotic. It is not in the deodorant recipe, just the deodorant bar. Is it necessary?

    Hello, I made a batch of deodorant using a smiliar recipe of coconut oil, baking soda, cornstarch, arrowroot powder and Tea treeoil. I have been using it for about 3 weeks and it is working great, but I have found my armpits to be getting sensitive and a little sore in some areas, I believe it is due to the baking soda. I am going to make another batch without the baking soda. I see that you use pro-biotics, what role do they play in preventing odor or wettnes?

    Also, I love your website, it has inspired me to lead a healthier and cleaner life!! thanks for the inspiration.

    I am a breast cancer survivor who wanted to go to a natural deodorant. I am a very “fragrant” sweater and even had problems with the strongest anti-perspirant deodorant out there. Every natural product I tried let me down in hours. Until you. I made your recipe that uses baking soda, beeswax, mango butter, cocoa butter, coconut oil, probiotic capsules, etc. believe it or not, I can go for two days and still not smell! I am thrilled to pieces! Thank you SO MUCH Katie!

    you are BRILLIANT! I have spent hundreds of dollars over the years trying out every natural deodorant on the market that i could find. I recently found a few that were OK, but still, it sucks to settle when it comes to deodorant. I made a batch with your recipe this weekend and it is WONDERFUL! so far, no odor at all! thank you so much for sharing! I have made so many things from your recipes and love them all!

    I made the deodorant bar for the second time last night and it’s still quite soft (won’t come out of the deodorant applicator and can’t unmold it). Can I remelt it and add more baking soda and arrowroot? Or add beeswax?

      I haven’t actually made this recipe yet, but I would do beeswax to make it harder. Katie talks about doing that in some of her other recipes like with the lip chap she says ” If you prefer a firmer and longer lasting lip chap, you can add more beeswax, up to double the recommended amount. If you prefer a smoother and more oily lip chap, you can reduce the amount of beeswax.” So that’s my guess, hope it helps!

      1. Carine Avatar

        I added beeswax and it did make it harder. Now, since I’m still on the last batch I don’t know if it’s too hard or not but it is coming out of the applicator. I forgot that if your house is a bit warm ( I live in the great white Canadian north) you can keep it in your fridge, which I did and it works…
        Thanks Ravenna Black!

          Hi! Did you simply melt the entire thing and add more beeswax? I was wondering if that were a bad thing to do, since powders and EO are added after the jar is removed from heat. I’m somehow thinking maybe keeping EO and the powders in the double boiler on heat destroys their properties…?

    I made the deodorant but mine melts in heat just like the coconut oil… did I do something wrong?

  13. Mandy Avatar

    I tried this recipe and i found it a bit hard to put on and then slightly sticky. Maybe i did something wrong? I have also tried the versions without beeswax. I love these, they work great, but it would be nice to use a bar….??

    can you just use arm and hammer baking soda and bob’s red mill arrowroot powder?

  15. BeK Avatar

    What if I wanted to use 3 different essential oils? Should I use 20 drops of each, totaling 60 drops in all?

    Okay, these are also awesome. I’m so happy to have finally found a recipe that works, goes on smooth and clear and is not slimy. I went with arrowroot and no baking soda since I’ve had irritation with baking soda in the past. Thank you so much for these recipes Katie! They are lifesavers!

    I love the idea of using probiotics! Can I use a probiotic that does need to be refrigerated if I keep it in the fridge?

      What purpose do the probiotics serve? are they just a preservative?

    I never comment on any websites but I just had to comment on this. I’m
    currently trying to transition in to an all natural life and I’ve been
    finding it so confusing and hard and lots of ingredients I’ve never
    heard of before. This deodorant is the first I’ve tried and omg! It’s
    amazing. If normal store bought deodorants had no bad chemicals in them I
    still would use this natural recipe because it’s the best deodorant
    I’ve ever had. Today was the perfect test as it was my first day of
    college and I was sweating like mad! But I still am dry and smells great
    (I used lavender oil in it) and all my clothes have been smelling good
    at the end of the day which is a first! My brothers have even started
    using it and usually the minute you say the word “natural” they’re like
    BLAH BLAH BLAH NO! haha so just wanted to thank you for making this
    transition easier for me. I can’t wait to try other recipes 🙂 Big
    thanks from Ireland! <3
