The woman who isn't hungry and eats anyway. Who finishes dinner and goes looking. Who opens the desk drawer at 3 without deciding to. Who knows the kitchen is closed and goes back in at nine.
It's also for you if you've been looking at the prescription route and wanted to try something simple first, or if you came off one and want a daily habit in place before the noise gets loud again.
It is not for you if you're looking for a number on a scale by a certain date. This is a quieter thing than that.
Two bottles of Blue Burn, a 60-day supply, for $29.95 instead of $98. Plus the Food Noise Reader, a short guide to what the 3pm snack and the 9pm fridge are really about, sent to your email after checkout.
After the kit, 2 bottles arrive every month at $29.95, which is 38% off. Skip, pause or cancel from your account or by emailing support@purrityco.com. No calls, no forms.
Short version: bitter first, then eat.
Most modern food is soft and sweet and never hits the bitter receptors on your tongue. So your body never gets the “a meal is starting” signal, and never really gets the “that was enough” one either. An hour later it’s asking again. That asking is the food noise.
Blue Burn is bitter on purpose. One dropper on the tongue ten minutes before you eat. Lemon peel, ginger and gymnema wake the signal up. Gymnema also changes how sweet things taste for a while, which is why the after-dinner cookie loses its pull. Ashwagandha covers the stress part, because a lot of the 9pm fridge trips were never hunger.
Then dinner ends and it’s just over. No scanning the pantry. No planning tomorrow’s lunch. Quiet.
Two weeks. That’s the honest answer for most women. Some notice it after the first dinner. Some need the full month. This is a before-meal habit, not a switch.
The first thing you’ll notice is the taste. It’s bitter. That’s the plants doing their job, not something to fix. If you can’t take it neat, water is fine.
The second thing you’ll notice is what you don’t do. You don’t wander back to the kitchen after the dishes. You don’t open the desk drawer at 3. Dinner ends and the night just carries on.
Don’t judge it on the scale. Judge it on the nights you close the kitchen and it stays closed. That’s what the 60 days are for.

A note from Purrity
You had dinner. You did the dishes. Maybe you even brushed your teeth at 8 so you couldn’t eat anything after. And at 9 you were standing in front of the fridge anyway, not hungry, just looking.
That is not a willpower problem. It is a signal problem. Most of what we eat now is soft and sweet and never gives your tongue the bitter note a meal used to start with, so your body never quite hears that a meal happened.
Blue Burn is bitter on purpose. One dropper, ten minutes before you eat. Then dinner ends and it is just over. That is the whole promise. Quiet, not a number.
The Purrity team
Why this exists
You’ve done the things. Protein at every meal. The big bottle of water. Brushing your teeth at 8 so you can’t eat anything after. Saying “you’re not hungry, you’re just bored” out loud in your own kitchen. And it works, for a night. Then it’s 9pm and you’re standing in front of the fridge again, not even hungry, just looking.
Here’s the part nobody tells you. Most of what we eat now is soft, sweet, and gone in a few minutes. It never gives your tongue the bitter note that used to open every meal, so your body never quite registers that a meal happened. An hour later it’s asking again. That asking is the food noise. It’s not a character flaw. It’s a missing signal.
Blue Burn puts the signal back. One dropper on the tongue before you eat. Lemon peel, ginger and gymnema tell your body food is coming. Gymnema changes the way sweet things taste for a while, so the cookie after dinner loses its pull. Ashwagandha is in there for the stress part, because most fridge trips were never about hunger.
What it feels like is quiet. Dinner ends and it’s just over. You’re not scanning the pantry. You’re not planning tomorrow’s lunch while you’re still eating breakfast. Food stops running your day, and you get the day back.

Blue Burn
About 74 cents a day on the 4-bottle bundle.
Take 1 full dropper about 10 minutes before your meal. Place it straight on your tongue, or mix it into a small glass of water if you’d rather not taste it.
Take it daily, up to 3 times a day, for best results. Most women start with one, before whichever meal usually gets away from them.
For most women, around two weeks in. And usually at night, when they’d normally head back to the kitchen and just don’t. Some feel it after one dinner. Some need the full month.
There’s no promised timeline, which is exactly why you get 60 days to find out.
No, and it isn’t meant to do that. You’ll still be hungry at mealtimes. What gets quieter is the in-between: the 3pm snack, the after-dinner sweet thing, the fridge at 9. Eat your meals.
Ask the doctor who prescribed it first. That isn’t us dodging the question, it’s the only honest answer when a prescription is involved.
What we can tell you is exactly what’s in the bottle: eight plants in vegetable glycerin and water. No stimulants, no alcohol, no sugar, nothing that needs a pharmacy. Take the ingredient list to your appointment.
A lot of women find us on the way to that decision, and a lot find us after, wanting a simple daily habit in place before the noise gets loud again.
Capsules go straight past your tongue to your stomach, and your tongue is where the signal starts. By the time a capsule dissolves the meal is already underway.
Blue Burn goes on the tongue, bitter, ten minutes before you eat. That’s how bitter plants have always been taken, and it’s why the taste isn’t a flaw to fix. Gymnema is in there for the sweet cravings, ashwagandha for the stress that sends you to the fridge when you’re not hungry.
The difference isn’t a stronger ingredient. It’s that the signal actually arrives.
Because bitter is the point. That taste is the signal that tells your body a meal is coming. Sweeten it and you’ve removed the thing you bought it for. Water is fine if you can’t take it neat.
It’s eight plants you already know, in vegetable glycerin and water. No alcohol, no sugar, no stimulants.
If you’re pregnant, nursing, or on medication, check with your doctor first, the way you would with anything new.
