7 Things Women Over 40 Should Know About Vaginal Odour

2. Your Vaginal Microbiome Changes Too

After 40, your body starts playing by different rules.

Estrogen levels can fall during menopause. And the vaginal microbiome can shift along with them.

Your vagina relies on bacteria called Lactobacillus

These bacteria produce lactic acid, helping maintain an acidic vaginal environment that can limit the growth of certain unwanted microbes.

And that "good" bacteria? It can decline too.

Here's why this matters:

A change in vaginal odour isn't necessarily a cleanliness problem. Hormonal changes can affect the vaginal microbiome, and washing the outside won't directly restore the bacterial balance inside.

You can't wash away a microbiome change. And more scented products aren't the answer to every change in vaginal odour.

What the Research Says

3. Some Products Can Make Things Worse

Wipes. Washes. Sprays. Products promising to keep you smelling fresh all day.

Maybe you've tried them all like me. Maybe you're using one right now.

Here's something worth remembering: the vagina is self-cleaning.

Scented wipes and harsh washes can irritate sensitive vaginal tissue and disturb its natural environment.

If your GP prescribes vaginal estrogen such as Vagirux for menopausal symptoms, that serves a different purpose from a scented wash. It isn't a product specifically approved to treat vaginal odour.

And because menopause can change the bacteria living inside your vagina, understanding your vaginal flora is another useful part of the conversation.

That's the difference nobody talks about.

The bottom line? Your vaginal flora deserves attention too.

4. You Don't Want To Remove All Bacteria

This is where most women get it backwards.

Bacteria aren't automatically bad.

Your vagina naturally contains bacteria.

And Lactobacillus species are commonly found in healthy vaginal microbial communities.

But here's where menopause makes things more complicated.

As estrogen declines, the vaginal environment changes, and Lactobacillus bacteria can become less abundant.

Stop treating every bacterium like the enemy.

Once you understand that, probiotics start making more sense.

But there's another trap.

Not every probiotic is the same.

5. "General" Probiotics Aren't All The Same

Maybe you tried probiotics. The ones your friend recommended...

The ones labelled "women's probiotics."

You took them for weeks. Maybe months. And... nothing.

Here's why: Most probiotics are designed for gut health. Different bacteria. Different location. Different problem.

A bottle saying "probiotic" doesn't mean it's formulated with the bacterial species commonly found in a healthy vaginal microbiome.

One formula might have 1 billion CFU and another might have 5 billion CFU.

One might contain one species and another might contain six.

One might include a prebiotic and another might not.

Same word on the front.

Completely different formula on the back.

6. First, Check The CFU

Look at the number.

1 billion?

5 billion?

CFU is used to state the amount of viable microorganisms in a probiotic.

That's a big difference on the label.

But don't stop there.

Because 5 billion of WHAT?

That's the next thing you check.

7. Then Check The Species

Two products can both say 5 billion CFU.

That doesn't mean they're the same.

One might contain one probiotic species.

Another might contain several.

So read the names.

Don't just read the number.

Now there's one more thing to look for.

A prebiotic.
