5 Antibacterial Uses of Apple Cider Vinegar

5 Antibacterial Uses of Apple Cider Vinegar

Apple cider vinegar (ACV) is known to make your hair shiny, help with weight loss, balance your pH, cleanse your lymphatic system, kill bacteria and so much MORE. Today, I’m going to be sharing 5 ways you can use ACV to get rid of BACTERIA! 



I’ve said it a million times before, but I’ll say it again – SWEAT + BACTERIA = BAD ODOR. Wearing deodorant alone will NOT keep smelliness at bay, you NEED to eliminate the odor causing bacteria. That’s where ACV comes in. ACV has ACETIC ACID  which kills bacteria by passing through into the bacteria’s cell membranes and neutralizing it.

TIP: Use a gentle antibacterial soap formulated with ACV, like the underarm bar. Or splash some ACV on a cotton pad and swipe onto your underarms after showering.

Does your carpet have a funky smell? Carpets are essentially giant sponges that soak up odors from cooking, pets, and moisture from humidity/spills. Trying to cover up the scent with an air freshener is like spraying perfume as a substitute for a shower – gross and ineffective! Solve the problem at the root by killing the bad bacteria with ACV! 

TIP: Make your own fabric/surface cleaner by diluting 1 tbsp of ACV in 1 cup of water. Add a few drops of lemongrass or lavender essential oil to get rid of the ACV smell.



More than 50% of people have bad breath, and reportedly 80 million people in the U.S. suffer from chronic halitosis (bad breath). The reason? The temperature inside of your mouth can reach up to 37°C with 96% humidity – perfect for bacteria to thrive and grow. And guess what? Your mouth is home to over 500 strains of bacteria! Drinking ACV can help fix bad breath!

TIP: Every morning, dilute 1 tbsp of apple cider vinegar with 1 cup of water and drink on an empty stomach. You can add some lemon juice and maple syrup if you can’t stand the smell/taste of ACV. This drink will not only cure bad breath, but will also help with digestion!

As many as 1 in 4 women in the United States have BACTERIAL VAGINOSIS (BV). The most common symptom of BV is a foul-smelling, fishy odor coming from the vagina – caused by, you guessed it, bacteria. The antibacterial properties of ACV will help alleviate odor.

TIP: Make a vaginal wash by diluting 2 tbsp ACV in 1 cup of water and use as an in-shower rinse.



Two causes of dandruff are an excess of the bacteria, MALASSEZIA YEAST, and a scalp pH impalance. ACV has both antibacterial properties to kill off yeast and a highly acidic pH which can help balance out the scalp.

TIP: Dilute 1 tbsp of apple cider vinegar in 1 cup of water and rinse your hair with it in the shower. Allow the solution to sit on your scalp for a few minutes before washing out!

It’s important to remember that ACV is a very POWERFUL and POTENT ingredient, often too strong to be used alone! Always DILUTE with water!

5 Ways To Naturally Whiten Teeth

5 Ways To Naturally Whiten Teeth

Traditional teeth whitening products like whitening strips can be very harsh on the tooth enamel and increase tooth sensitivity. That being said, many people feel self conscious about their smile and associate pearly whites with a healthy mouth. Today, I’m going to be sharing 5 gentle and natural ways you can whiten your teeth at home.



The magic ingredient! If you didn’t see my last post on 5 ways to use ACV, make sure you do! Apart from those 5 reasons, turns out apple cider vinegar is great for stain removal! The acetic acid is amazing at killing bad bacteria and ACV’s acidic pH is very effective at breaking down plaque and stains! 

TIP: Soak a cloth in ACV and gently rub on your teeth for 30 – 60 seconds. Rinse well with water after.

Similar to ACV, lemon peels have CITRIC ACID – a powerful ingredient that removes stains. Though this is a natural remedy, citric acid is strong and it’s important to use it gently and moderately to ensure enamel health.

TIP: Gently rub a lemon rind on your teeth for 30 – 60 seconds. Rinse well with water after.

This is probably the yummiest remedy I’m sharing today. Just like lemon rinds, strawberries are rich in citric acid. They also have a little bit of MALIC ACID (also found in apples) and the two acids combined are great at breaking down plaque.

TIP: Mash up 2-3 strawberries and gently rub on your teeth for 30 – 60 seconds. Rinse well with water after.



SURPRISE! As much as I don’t like coconut oil for the skin, it does have some redeeming qualities- especially when it comes to plaque removal! The LAURIC ACID and CAPRIC ACID in coconut oil have potent antibacterial properties that tackle teeth staining plaque!

TIP: Put a spoonful of coconut oil in your mouth and swish it around for 5 – 20 minutes. Or add a few drops to on your toothbrush and brush your teeth as normal. Rinse well with water after.

Don’t be afraid of its color! Even though it’s black, activated charcoal can actually help to REMOVE stains from your teeth because of its detoxifying properties. We haven’t added this ingredient to many of our products for no reason!

TIP: Dip a wet toothbrush in activated charcoal and brush as normal. Rinse well with water after.

Remember, though these are natural options, they are still POWERFUL and should be used in moderation to avoid damaging your tooth enamel.

How to Use Apple Cider Vinegar for Body Odor

How to Use Apple Cider Vinegar for Body Odor

For years, I have raved about drinking apple cider vinegar shots every morning. Not only does it help control my sugar cravings and ease digestion, but I find it also helps boosts my immune system. This past winter where 90% of my team came down with the flu and germs were flying everywhere in the air, I did not get sick once. I actually believe it was thanks to my daily immunity boosts from ACV.

Why I love apple cider vinegar even more is because not only is it a powerful detox ingredient for our bodies, but it’s also very effective at neutralizing odor-causing bacteria on the skin.


How Does ACV Work?


If you’ve ever sniffed apple cider vinegar, you know it’s not the best smelling thing out there. I’ve heard many of my family and friends say that it smells like feet… Ok now, it does NOT smell like feet and although it does smell strange at first, you do get used to the smell and taste fairly quickly.  

Side note: If you’re struggling to drink ACV, here’s my tried-and-tested tip on making ACV taste delicious:

Add 1 tablespoon of ACV into ¼ cup of organic lime juice (I bought a bottle at Whole Foods), and ¼ cup of water. The lime juice helps to hide the ACV taste and I also have no time to cut limes and squeeze them in the morning, so store-bought lime juice works even better for me!

That unique smell of ACV comes from acetic acid. Acetic acid and other organic acids found in ACV are responsible for killing bacteria. It works by passing through into the bacteria’s cell membranes and neutralizing it.

It’s like Natural Clorox for Your Body

A study conducted by the Middlesex University London in the UK, tested different bacteria strains in petri dishes with apple cider vinegar and cultured them together at 37 degrees celsius for a 24 hour period.

The results showed that ACV reduced bacterial growth and eliminated bacteria types such as E. coli, C. albicans (which includes Corynebacteria, the type of bacteria that causes body odor) and S. aureus.

This means that apple cider vinegar has the ability to eliminate odor-causing bacteria and create an inhospitable environment for bacteria to grow when applied on the skin. The best part is that unlike Clorox bleach which is highly toxic, apple cider vinegar is 100% natural and safe for humans.

Individuals suffering from excess body odor would be able to reap the antibacterial and deodorizing benefits of apple cider vinegar.

3 Ways to Use Apple Cider Vinegar on Your Armpits


Body Odor Eliminator

ACV’s antibacterial properties will prevent bacteria from growing on your skin and will neutralize any odor-causing bacteria, keeping you smelling clean and fresh. If you’re doing an armpit detox or are naturally a smellier person, try using apple cider vinegar to get rid of body odor in your shower routine.

What to do: Use a natural antibacterial bar soap formulated with apple cider vinegar in the shower like the underarm bar, or apply ACV onto a cotton pad and gently swipe onto armpits.


Lighten Dark Armpits

ACV helps to regulate the skin’s pH balance and gently exfoliates away dead skin cells, which works to gradually lighten dark armpits.

What to do:  Mix equal parts water and ACV in a bowl. Soak 2 cotton pads and apply onto each underarm like a sheet mask. Leave on for 15-20 minutes, then rinse with water water.


Armpit Detox

During the transition from antiperspirant to natural deodorant, try an armpit detox mask to help expedite the stages of detox and to pull toxins and aluminum chloride from your pores..

What to do: Mix 1 tablespoon of bentonite clay (I recommend the Aztec Secret Indian Healing Clay)  with ½ tablespoon ACV until it becomes a paste. Apply onto clean armpits and leave on 15-20 minutes or until dry. Rinse off and pat dry.
