Depression and Anxiety Are Not Caused by a Serotonin Deficiency

For decades, we’ve been told that anxiety and depression are caused by a “chemical imbalance”—a lack of serotonin in the brain. But this explanation simply isn’t true. Leading psychiatrists and researchers now agree that this theory is outdated and unsupported by science.

Tim Kendall, a respected psychiatrist and advisor to the British government, puts it bluntly: “I’ve reviewed the data, and it’s garbage.” Studies as far back as the 1970s found no significant difference in serotonin levels between people with depression and those without. What’s more, attempts to artificially lower serotonin in healthy individuals failed to create depressive symptoms—and some even reported feeling better.

Today, we know that anxiety and depression are far more complex. They are not caused by a “deficiency” but by patterns in the brain and body that we can learn to address. You don’t need to artificially boost serotonin levels to heal—you need a method that works with your mind and body to restore balance naturally.

Break Free from the Cycle of Fear—Naturally

In the last decade, prescriptions for antidepressants have more than doubled, yet the rates of anxiety and depression have also skyrocketed. Clearly, this isn’t the solution. So why keep doing the same thing and expecting different results?

Here’s the good news: you can break free from anxiety without relying on medication or endless talk therapy. Imagine a therapy that doesn’t involve painful exposure exercises or reliving past traumas, but instead gives you practical tools to take control of your emotions and reclaim your life. This method has already helped thousands of people just like you—and it can help you, too.

Sarah’s Story: From Fear to Freedom

Sarah, a 32-year-old mother of two, was once consumed by crippling anxiety. Leaving the house felt impossible, and she lived in constant fear of the next panic attack. Traditional treatments didn’t work for her, and she worried she’d never feel normal again.

Then she tried this new approach. Within weeks, Sarah began to notice real changes. She could go grocery shopping without fear, play with her kids without feeling overwhelmed, and finally sleep through the night. Today, Sarah describes herself as “free”—not just from anxiety but from the idea that she needed medication to cope.

Her story is not unique. Thousands of others have found hope and healing through this proven method. And now, it’s your turn.

        “Thanks to your online therapy, I finally understood why I couldn’t get rid of my emetophobia until now. Just two weeks after working regularly with the 10-sentence method, I noticed how this fear, which has been with me since I was 16, became much less severe.
