The Killer, made of boric acid, is a vaginal suppository designed to support healthy levels of vaginal yeast and a balanced vaginal microbiome.
Boric Acid is a white powder or colorless crystal that balances yeast in the body. Boric acid has been used for over a hundred years for vaginal health support when it comes to keeping one’s vaginal flora balanced. A balanced vaginal flora = a healthy vagina!
The Killer is a vaginal suppository — not a pill you take by mouth. We know it looks similar, but this will be inserted vaginally.
To use: Wash your hands well to gently insert The Killer with your fingers into your vagina. It should be inserted a comfortable amount, which should be far enough that it won't have the chance to slip out. There is no need to alter the capsule in any way. Just pop it in — that's it! Within a few hours, the capsule will start to dissolve and get to work.
Discharge is expected when using a vaginal suppository, so we recommend wearing a panty liner to help keep you clean.
We recommend using it at bed time so it can be one less thing you have to worry about during the day as it can cause discharge.
How long you use The Killer depends on your body and your needs. You can use The Killer for as little as 1-3 days or for as long as 7-14 days (an entire box). We recommend use of only one suppository every 24-hour period.
While both products are vaginal suppositories, they focus on different aspects of vaginal health.
Flora Power™️ is designed to support healthy levels of vaginal bacteria and help maintain a fresh vaginal odor. On the other hand, The Killer®️ is designed to support healthy levels of vaginal yeast.
They can definitely work together to keep a healthy and balanced vaginal microbiome. To use both The Killer and Flora Power™️, we recommend using The Killer between 1 to 14 days to help balance vaginal yeast and pH. After The Killer®️, you can use Flora Power™️ for as little as 1 to 5 days to help manage vaginal bacteria afterwards!
With the use of The Killer to help support a balanced vaginal environment, you can expect to experience a reduction in the itching and irritation which can often be associated with a yeast imbalance. Depending on your body and needs, you may see results in as little as one day or up to five days. Having a consistent regimen will be critical for managing a healthy vaginal yeast.
The Killer was designed to support healthy levels of vaginal yeast. If you’re looking to maintain fresh vaginal odor, we recommend trying Flora Power. Flora Power focuses on supporting balanced vaginal pH and bacteria — it’s great for those looking for freshness!
No — The Killer is a vaginal suppository and is meant to only be inserted into the vagina. Do not insert The Killer into any other part of your body.
The Killer is not vegan due to the gel capsule, but it is both gluten-free and dairy-free.
There are many different types of acids with ranging levels of pH (or potential of hydrogen, which is the measurement used to determine acidity). Many acids are “weak acids,” meaning they are safe to use. Common things in your house that contain weak acids are coffee, vinegar, and lemons.
Similarly, boric acid is a very weak acid and has many health and wellness uses, so don’t be scared by its name! The Killer was formulated by a medical doctor and is manufactured with pharmaceutical-grade boric acid in our FDA registered facility according to CGMP standards – meaning, it’s safe to use as directed!
We recommend waiting until the end of your period (or almost the end) before beginning to use The Killer.
We recommend waiting 24-48 hours after using The Killer before having sex.
Given that everyone is different and unique to their health, we recommend checking in with your doctor to make sure there are no interfering or contradicting ingredients between your birth control and The Killer.
The Killer is not approved for use if you are pregnant or breastfeeding. Please consult with your doctor to see which products may be most suitable for use while you are pregnant or breastfeeding.
For complete vaginal care, we recommend pairing The Killer® with:
If using The Killer® with Flora Power™, you'll want to complete use of The Killer first, wait 1-2 days, then using Flora Power™.
As always, anytime you add anything new to your regimen, we recommend checking in with your doctor/healthcare provider to ensure it makes sense for you, and they can answer any more specific questions you might have!
