You feel a little off, and you are standing in front of two Love Wellness suppositories wondering which one is yours. The Killer® or Flora Power®? They look alike and live in the same part of your routine, but they do different jobs.
This guide breaks down what each one supports, how they differ, and how to use them, so you can match the right vaginal suppository to what your body is asking for.
What Can Throw Your Vaginal pH Off
A healthy vagina is naturally acidic, and that acidity is held in place by good bacteria, mainly Lactobacillus, that keep less friendly microbes in check.
When your pH gets disrupted, those good bacteria decline and the balance can tip toward odor, irritation, or the overgrowth behind bacterial vaginosis and yeast infections. For the full picture, see our guide on how to balance your vaginal pH.
Plenty of everyday things can move your pH out of range:
- Hormonal birth control, IUDs, and natural hormone shifts
- Antibiotics and certain other medications
- Sex, especially without a condom
- Diet, stress, and not enough sleep
- Harsh or heavily fragranced hygiene products
What's Normal, and What's Worth a Closer Look
Your vagina is supposed to have a scent, and yours is your own. A healthy one often smells a little musky, sometimes a bit metallic around your period, and it can shift after sex. Discharge also changes through your cycle, from clear to creamy to stretchy.
A little itching now and then is usually nothing. It is the bigger, sudden changes that are worth attention: a strong or fishy odor, persistent itching or burning, or discharge that looks very different from your normal.
Common Causes of Vaginal Odor
Most odor traces back to a handful of usual suspects:
- Bacterial vaginosis, known for a strong, fishy smell
- A forgotten tampon
- Hormonal changes
- Sweat
- Your diet
- Certain medications
Your vagina does a good job of cleaning itself, but when a smell is clearly different from your normal, that can be a sign the balance needs support.
BV vs. Yeast: How to Tell the Difference
BV and yeast infections share a lot of symptoms, so it can be hard to tell them apart on your own, and our BV vs. yeast infection comparison goes deeper. A provider can take a quick culture and give you an accurate diagnosis, which is always the best starting point. As a general guide, here is how they usually differ.
Signs that point to BV
- A strong, fishy odor
- Thin, grayish discharge that can look foamy
- Itching, burning, or irritation
- Discomfort during sex
- It is also common for BV to show no symptoms at all
Signs that point to a yeast infection
- Usually no strong odor
- Thick, white, cottage cheese-like discharge
- Itching and swelling around the vulva
- Burning, sometimes when you pee
- Discomfort during sex
A few things make yeast overgrowth more likely: estrogen shifts from birth control or pregnancy, a round of antibiotics, and sitting in wet or sweaty clothes, which creates the warm, damp setting Candida loves. So change out of a wet swimsuit or workout leggings sooner rather than later.
A Quick Note on Prescription Treatments
If you have an active infection, your provider may prescribe an antifungal for a yeast infection or an antibiotic for BV. These can clear an active infection, but broad treatments sometimes knock out good bacteria along with the bad.
That is part of why infections can return, and why a balance-first routine has a place between episodes. Suppositories like these support a healthy environment. They are not a replacement for the treatment your provider prescribes.
How The Killer® and Flora Power® Differ
Both are simple, easy-to-use vaginal suppositories, and both are free of fragrance, essential oils, and other common irritants. The difference comes down to what is inside and what it supports.
The Killer® has one ingredient: boric acid. It works locally to control vaginal odor and support a balanced pH within the healthy, normal range, along with healthy levels of vaginal yeast and bacteria.
In a third-party study, 94% of women experienced less unusual vaginal odor within seven days of daily use. Our full guide to boric acid suppositories covers how it works in more depth.
Flora Power® pairs a vaginal probiotic blend with Vitamin C. The probiotics help replenish the Lactobacillus that keeps your environment acidic, and the Vitamin C supports that healthy, acidic pH. It is made with clinically studied ingredients and is built to support a fresh, balanced environment.
Here is the quick cheat sheet:
| The Killer® | Flora Power® | |
|---|---|---|
| Main ingredient | Boric acid (single ingredient) | Vaginal probiotic blend + Vitamin C |
| What it supports | Odor control and balanced pH | Replenishing good bacteria and a fresh, balanced environment |
| Best for | Odor and freshness, a quick pH reset | Maintaining good bacteria and pH over time |
| Format | Fragrance-free suppository | Fragrance-free suppository |
| Typical use | Once daily for 1 to 14 days | Once a week, or up to once a day for 5 days |
How to Use Each One
Both go in the same way: with clean hands, insert one suppository before bed, the same way you would a tampon. Expect some watery discharge overnight as it dissolves, and wear a thin liner to stay comfortable. Empty your bladder first, especially after sex.
For The Killer®, use one suppository before bed for anywhere from 1 to 14 days. Many women keep it on hand for the moments their body feels off, like after sex, at the end of a period, or after a diet shift.
For Flora Power®, use one before bed once a week, or up to once a day for as many as 5 days when you want extra support. Wait at least 5 days between courses, and stick to one suppository per day.
Using them together
The two work well as a pair. A common rhythm is to use The Killer® first for 1 to 14 days, then a few days after you finish, follow with Flora Power® for 1 to 5 days to support a healthy pH balance.
For ongoing maintenance, many women use Flora Power® once or twice a week and The Killer® about once a week, on different days.
If you think you have an active infection, get a diagnosis first and follow your provider's plan. These suppositories support a balanced environment around that care.
Build Your Vaginal Care Routine
Suppositories do their best work as part of a bigger routine. A few staples worth keeping on hand:
- The Killer® for odor support and a quick pH reset
- Flora Power® for probiotic pH support
- Good Girl Probiotics® for daily, oral microbiome support
- A gentle pH-balanced cleanser for the vulva
If you would rather start with a coordinated set, our vaginal health kits pair these pieces together.
Frequently Asked Questions
Can I use The Killer® and Flora Power® at the same time?
It is better to space them out. A common approach is to use The Killer® first, then start Flora Power® a few days after you finish. For everyday maintenance, use them on different days rather than together.
Which one should I reach for if odor is my main concern?
The Killer® is the odor-and-pH option. In a third-party study, 94% of women noticed less unusual odor within seven days of daily use. Flora Power® leans more toward supporting a fresh, balanced environment over time.
Do I need a prescription for either one?
No. Both are available over the counter. If your symptoms point to an active infection, see your provider for a diagnosis first, then use these to support a balanced environment around that care.
Can I use them on my period?
Flora Power® works best when you use it after your period ends. The Killer® can be used during your period, as long as you stick to pads rather than tampons or a cup.
How long until I notice a difference?
With The Killer®, many women notice fresher odor within a few days, and the study group saw less unusual odor within a week. Flora Power® is about steady, ongoing support, so it does its best work as a regular part of your routine rather than a one-time fix.
The Bottom Line
When you are deciding between the two, it comes down to what you need. Reach for The Killer® when odor and a fast pH reset are the priority, and for Flora Power® when you want to replenish good bacteria and keep your environment fresh over time. Used together, they cover both sides of a balanced routine.
For anything that feels like an active infection, let your provider diagnose it and guide treatment. Everything else is about small, steady support that helps your body feel its best, at every stage of life. Explore the full vaginal health collection to round out your routine.
