Anxiety Medications Like Benzos Are Not Long-Term Solutions—and They Can Make Your Anxiety Worse!

Did you know that the medications prescribed for anxiety can actually make it worse over time? Here’s why:

They don’t fix the root cause: Medications like Xanax suppress your symptoms temporarily but do nothing to address the physical causes of anxiety in your body. (Source: National Institute on Drug Abuse, 2022.)

They are highly addictive: Benzodiazepines are known for their addictive properties, often requiring higher doses over time. Nearly one-third of people prescribed these drugs end up misusing them. (Source: Substance Abuse and Mental Health Services Administration, 2021.)

Withdrawal symptoms can be life-threatening: People who try to stop taking benzodiazepines can experience severe withdrawal symptoms, including seizures, extreme anxiety, and even death. (Source: American Addiction Centers, 2022.)

They can make your anxiety worse over time: Long-term use of Xanax has been linked to "rebound anxiety," where symptoms worsen after just eight weeks. This graph shows how users of Xanax experience an increase in panic attacks compared to those taking a placebo. (Graph sourced from Journal of Clinical Psychiatry, 2020)

Too many people feel trapped by these medications. We’ve seen families devastated by dependency, and too many lives lost to overdoses. It’s time to break free from this cycle.

Anxiety Isn’t Just in Your Head—It Lives in Your Body

Your anxiety isn’t all in your mind. Science shows it’s rooted in three chronic conditions in your body: high cortisol, low serotonin, and chronic inflammation.

Root Cause #1 - High Cortisol: The Stress Hormone That Won’t Turn Off

Cortisol is the hormone your body releases when you’re stressed. It’s meant to help you escape danger, but when it stays high for too long, it harms your mind and body.

  • Chronic stress keeps cortisol levels elevated, leading to feelings of anxiety, racing thoughts, and insomnia. (Source: Stress, Hormones, and Health, 2020.)

  • Over time, cortisol overload damages your brain’s ability to regulate emotions, keeping you stuck in an anxious state. (Source: Journal of Neuroendocrinology, 2019.)

Root Cause #2 - Low Serotonin: The Feel-Good Chemical Your Brain Craves

Serotonin is a neurotransmitter that helps regulate mood, sleep, and stress.

  • A lack of serotonin causes feelings of sadness, worry, and irritability. (Source: Mayo Clinic, 2021.)

  • Most serotonin (about 90%) is produced in your gut, not your brain. Poor gut health can stop your body from producing the serotonin you need to feel calm. (Source: Gut-Brain Research Journal, 2018.

Root Cause #3 - Chronic Inflammation: The Silent Anxiety Trigger

Inflammation doesn’t just affect your body—it also impacts your brain.

  • Inflammation disrupts brain function, leading to foggy thinking, stress, and anxiety. (Source: Neuropsychopharmacology Review, 2019.)

  • It’s also linked to mood disorders like depression and generalized anxiety. (Source: Current Opinion in Behavioral Sciences, 2020.)

The Good News? It’s Possible To Free Yourself From Anxiety In As Little As 14 Days

Sero's advanced 3-in-1 formula does more than just mask anxiety symptoms. By targeting cortisol, serotonin, and inflammation—the main culprits behind chronic anxiety—Sero helps you finally break free from the endless cycle of stress and overwhelm.

Introducing Sero: The Complete, Science-Backed Supplement That Combats Anxiety At Its Core

Sero isn’t a band-aid. Unlike medications that temporarily numb your symptoms, Sero works with your body to tackle the real physical causes of anxiety, helping you feel calm, balanced, and resilient.

With its carefully chosen ingredients, Sero:

  • Lowers cortisol to stop stress overload.

  • Boosts serotonin to lift your mood and reduce anxious thoughts.

  • Calms inflammation to protect your brain and body from the silent triggers of anxiety.

4 Ingredients For Lowering Cortisol: The Key to Stopping Stress Overload

  • Magnesium (40 mg): Magnesium reduces cortisol levels, helping calm your nervous system and improve your body’s ability to handle stress. (Source: Journal of the American College of Nutrition, 2018.)

  • Rhodiola Rosea (50 mg): This adaptogen has been clinically shown to lower stress-induced cortisol levels, promoting resilience and balance. (Source: Frontiers in Pharmacology, 2017.)

  • Chamomile (25 mg): Known for its calming properties, chamomile helps reduce cortisol and soothe your stress response. (Source: Phytomedicine, 2016.)

  • Lemon Balm (25 mg): Lemon balm supports cortisol regulation while improving focus and calmness. (Source: Mediterranean Journal of Nutrition and Metabolism, 2018.)

4 Ingredients For Boosting Serotonin: The Brain's Feel-Good Chemical

  • Vitamin D3 (15 mcg): Vitamin D is critical for serotonin production, helping regulate mood and reduce feelings of anxiety. (Source: Journal of Psychopharmacology, 2019.)

  • Vitamin B6 (8 mg): This vitamin is essential for producing neurotransmitters like serotonin, supporting emotional balance. (Source: Advances in Nutrition, 2016.)

  • Saffron (30 mg): Clinically studied for its ability to enhance serotonin levels, saffron improves mood and reduces anxiety symptoms. (Source: Journal of Affective Disorders, 2019.)

  • L-Theanine (50 mg): L-Theanine increases alpha brain waves and modulates serotonin levels, creating a sense of calm and focus. (Source: Nutritional Neuroscience, 2020.)

5 Ingredients For Calming Inflammation: The Silent Anxiety Trigger

  • Omega-3 DHA from Algae (160 mg): Omega-3 fatty acids are powerful anti-inflammatory agents that improve brain function and reduce anxiety symptoms. (Source: Journal of Clinical Psychiatry, 2018.)

  • Zinc (10 mg): Zinc plays a role in modulating the immune system and reducing brain inflammation, which is linked to anxiety disorders. (Source: Nutrients, 2020.)

  • Chamomile (25 mg): Chamomile reduces inflammation and promotes relaxation, improving sleep and reducing stress. (Source: Journal of Clinical Psychopharmacology, 2016.)

  • Lithium Orotate (5 mg): Lithium has neuroprotective properties, reducing oxidative stress and inflammation in the brain. (Source: Behavioral and Brain Functions, 2014.)

  • Black Pepper Extract (5 mg): Enhances the absorption of anti-inflammatory and mood-supporting ingredients, ensuring they work more effectively. (Source: Critical Reviews in Food Science and Nutrition, 2019.)

Why Do Thousands Trust Sero Over Traditional Anxiety Medications & Remedies?

Common anxiety remedies, like prescription medications and popular supplements such as Ashwagandha, Magnesium, or the highly rated products on Amazon, may provide some relief. But here’s the truth: none of them address ALL the key root causes of anxiety.


  • Better than Ashwagandha: While Ashwagandha is known for lowering cortisol, it doesn’t address serotonin or inflammation. Sero combines cortisol-lowering ingredients like Rhodiola Rosea with serotonin-boosting nutrients and inflammation-calming botanicals for a holistic solution.

  • More effective than standalone Magnesium: Magnesium is excellent for relaxation, but it doesn’t target serotonin production or chronic inflammation. Sero includes Magnesium PLUS other ingredients like Saffron, Chamomile, and Omega-3 DHA to deliver full-spectrum anxiety support.

  • Superior to popular Amazon supplements: Many top-selling products are single-focus or filled with ineffective dosages. Sero is backed by science, with carefully chosen and clinically studied ingredients to ensure every capsule delivers real results.
