Your sleep is attacked by two forces every night.

Inside your body

Your nervous system stays overstimulated to fall asleep. Magnesium levels drop. Your muscles stay tense.

Outside your body

Your bed contains billions of microscopic dust allergens. They irritate your lungs, disrupt breathing, and fragment sleep cycles.

Sleep BioClear⁺ fixes both at once.

Magnesium glycinate

Magnesium glycinate

Calms a racing mind

What it
is:

The highly absorbable form of magnesium your brain uses to slow down.

How it
works:

Helps regulate neurotransmitters, including GABA.
(The main calming chemical in the brain.)

Why Magnesium Matters

310+ biological processes

in your body use Magnesium to function, from mental health, muscle function, and heart health

48% of Americans

are deficient in Magnesium intake compared to the recommended level.

THE mineral your brain uses to slow down.

Magnesium helps regulate NMDA receptors, preventing your neurons from firing nonstop at night. It supports GABA, the brain's main calming signal. Magnesium also helps muscles release tension so your body can fully rest.

See How Better Sleep Feels

I finally fall asleep without tossing and turning.

I used to lie awake with my mind racing. Within a few nights of using this spray, I was falling asleep faster and waking up feeling rested instead of groggy.

- Nataly L.

I wake up clearer and more refreshed.

I did not realize how much my bedroom air was affecting my sleep. This spray made my breathing feel easier at night, and my sleep feels deeper.

- Phoebe D.

No melatonin hangover.

I love that this does not knock me out or leave me foggy the next day. I just sleep better and wake up feeling like myself.

- Cecile R.

Easier mornings.

I used to wake up feeling sluggish. Now my mornings feel lighter and more refreshed. It really is amazing.

- MacKenzi S.

No more constant worrying

I didn’t realize how much background anxiety my allergies were causing. I was always mentally preparing for discomfort. This has helped so much that I don’t even think about it throughout the day anymore.

- Chris J.

Finally feel in control

My stress always spiked when symptoms started creeping in. The spray has cut down those reactions so much that I feel like I actually have control again instead of being controlled by my symptoms.

- A. Nguyen

Worth it!

Expensive but worth every penny!! I will be buying more for sure. Such a stress reliever!! THANK YOU!

- Elizabeth Jardine

I love this spray!

I used to get stressed anytime I felt a tickle in my throat or a little congestion. I’d assume a full reaction was coming. Now my symptoms stay mild, and that alone has eased so much anxiety.

- Elena

Noticed a difference in a day or two

I keep house very clean, but it’s hard to keep all the dust away. That’s where Pacagen came in. After I used it the first time all over my house, I found my nose wasn’t stuffy first thing in the morning, and over the next few days my energy came back.

- Megan G.

Wonderful and effective product

My allergic reaction has been mostly cleared up. I can breathe and stopped sneezing. My eyes aren't itchy and my nose is not running.

- Leslie F.

Has really helped my boyfriends allergies

Once I moved into my boyfriend's house, we quickly realized we wanted to find an alternative to him take a daily allergy pill. This spray has helped tremendously with his symptoms (stuffy nose, itchy/water eyes, sneezing).

- Brittany L.

I can breathe again!

I’ve been been waking up without a stuffy nose, red, gritty eyes and a scratchy throat. This made a huge difference. Now I’m a subscriber.

- Shorekitten

A better life

We are very satisfied with this product and would highly recommend it. My mom is back to sleeping all night with no coughing... This product is awesome, it really works i mean it really really works.

- Mike B.

This has helped my son!

My son used to have to take allergy medicine everyday, sometimes twice a day, for his sneezing and coughing... Now we use the Pacagen spray every other day and he doesn’t need any allergy medicine! I’m so impressed and grateful!

- Jojo S.

This spray really works!

The first time I sprayed Pacagen on my curtains, carpet, bedspread, I actually did not cough the whole night... I will definitely keep ordering!

- Bethany S.

Works perfectly!

I had been struggling to take a deep breath for weeks, but within 20 minutes of first spraying the neutralizing spray, I could take a breath without needing to cough! This product truly works!

- Andrew P.

No massive attacks

She was having a pretty bad allergy attack at least once a week, sneezing a LOT, itchy nose and eyes and just really really miserable. She has not had ONE since we started this.

- Jess A.

No more morning sneezes

My morning sneezes, itchy eyes, and phlegmy cough are gone! The air in my apartment feels lighter too. LOVE this product!!!!

- Angie D.

Breathing easier, both of us, and I didn't think I was allergic

Just under two weeks ago we received our first Pacagen shipment. My wife’s allergic symptoms are noticeably diminished; late-night coughing and itchy eyes haven’t been a problem.

- Pieter B.

No more puffy eyes

Since using Pacagen products, I no longer have puffy eyes and I wake up feeling energetic and focused. After suffering from allergies all my life, I'm finally feeling some relief 😻

- Jessica G.

My skin finally calmed down

I’ve struggled with random flare-ups on my arms and chest for years. After incorporating this into my routine, the redness and small bumps started fading within days. I feel so much more comfortable in my own skin.

- L. Carter

Huge relief

I wasn’t expecting much, but this actually soothed the itchy patches I kept getting. My skin feels clearer and less irritated overall, which has been a major confidence boost.

- Jonah R.

It's amazing!

AMAZING results!! For years I dealt with sudden, unpredictable hives. Since using the spray, those reactions have basically stopped. I didn’t realize how much stress they were causing until they were gone.

- Marissa S.

OUTSTANDING Results!

10 years ago I developed hives along with my respiratory and sinus issues. I literally tried everything. As a last resort I ordered Pacagen. Within an hour I could already tell the difference...Unbelievable!!
