Q. “I read in our local newspaper about using Milk of Magnesia to prevent body odor.  I called the company asking about the risks of long term usage and they have none.

“Do you know if using milk of magnesia on your underarms causes problem over the long term?

“It works great and my son is thankful. We both use it daily.  No body odor here.”

A. Our only concern about using liquid milk of magnesia off the shelf is the preservative sodium hypochlorite (bleach). Although it is probably found in low concentrations and the FDA has apparently approved this ingredient for oral use in this liquid laxative, we have some reservations about regular ingestion or application to delicate underarm tissues. That is one reason why we have developed The People’s Pharmacy MoM (milk of magnesia) Roll-On Deodorant. To learn more about the history of this product, here is link to a short video.

Readers report that MoM can be helpful for a range of conditions. Just recently we heard that some women were using it to banish breast rashes:

“I have been using the People’s Pharmacy MoM deodorant under my breasts for itchy fungal rashes. I use my hair dryer to dry the MoM. The rash usually clears up in 2 days. LOVE MOM!” Joann

“I read your comments about using milk of magnesia as a deodorant, and was VERY SKEPTICAL.  I had tried vinegar, regular and so-called ‘natural’ deodorants, but nothing worked.  So I thought, why not?  I am shocked and gleefully excited to say that it works!!  After my shower last night I put some on (I usually get funky overnight).  I woke up fresh as a daisy.”

“I put a little more on this morning, and today in Chicago it is in the upper 80’s and humid!  I am still dry and fresh!  I have suffered with STRONG underarm odor since I was 12 years old, and believe me, as a woman, it is embarrassing.  I am so happy to have found something that works.  I just wish I had known about this sooner.  I have spent so much money on other things to no avail.  And MOM is only 6 dollars a pop, and will probably last me at least 2 months/bottle.

“Thanks to all of you for your comments.  They made me brave enough to try MoM and I am glad I did!  I will keep you up to date on my progress, but I am telling EVERYONE I KNOW TO TRY THIS!!!  What a blessing!” Debra

Not everyone is satisfied with MoM. It is not an antiperspirant, so there is some sweating going on. But if you would like to learn more, here is a link to aluminum-free MoM from The People’s Pharmacy.

    After a week of using the MoM deodorant my underarms are very itchy. Is this normal?

    I love the thought of using MOM, but I wonder what the risk is for Breast Cancer?

    I started using lemon juice (fresh) for deodorant, and then a warning on citrus came out, with a link (don’t remember the risk stats) to Breast Cancer. The study was not conclusive, but I took it as a yellow flashing light. I’m wondering about the safety of MOM as well.

    There are 118 elements, many with risk, so when my friends boast “it’s natural”, I reply, “So is arsenic, what’s your point?”.

    There are a multitude types of BC, and although I am fairly educated on BC, I don’t want to learn 1st hand.

      We are not aware of any breast cancer risk with magnesium, but we will be on the lookout for such research.

    Re: milk of magnesia for under the arms, I had read and heard about using MoM for a deodorant on PP and this came in handy when I suddenly developed underarm rash from every deodorant I used. A Secret women’s product started the trouble and MoM got me through weeks of recovery to ease the itch and function as deodorant–I still sweat but didn’t smell and this was fine. I then tried Burt’s Bees deodorant and launched right back into trouble. (In their defense, they took all my feedback and gave me a generous coupon to compensate.) Now I don’t dare try anything for fear of flare up. I read on the internet from others with this underarm problem that once it starts, you can be sensitive for months! MoM even started worrying me. (I will try your actual MoM deodorant product.) I now use Burt’s Bees lotion and dust on my combo of corn starch and baking soda. I can’t believe what torture this has all been and I am grateful for info from everywhere I found help. Thus I share my experience.

    Since I gave birth to my daughter, no deoderant has worked for me. I started trying my husbands an have to apply 5+ times a day. I ordered the mom to give it a shot. Seems to make me instantly stinky, even when I’m not sweating. Was a waste of money for me

    can please someone tell me if milk of magnesia used as deodorant over a long period of time has its ill effects? I have family history of breast cancer so don’t want to use any harmful chemicals. Thanks
    People’s Pharmacy response: We are not aware of any. We will, however, be on the watch for reports.

    How much does it cost?
    People’s Pharmacy response: Our original MoM deodorant costs $5.95. The newer aluminum-free version (no bentonite as stabilizer) is $6.25 because the synthetic stabilizer costs more but does not have the trace of aluminum bentonite contains.
