TL;DR

Depression and anxiety are often treated with medication, but research shows drugs alone rarely fix the root problem. Inflammation, nutrient deficiencies, thyroid imbalance, microbiome disruption, and stress chemistry are all strongly linked to mental health.

For many, progress comes from supporting the body’s natural systems. Following the Roadmap to Health diet, adding benfotiamine (1/day), lithium orotate (1/day), and a high-quality B complex (1/day), and working with a natural healthcare practitioner to check thyroid and adrenal health can make a life-changing difference. The diet change and supplementation works well for many people.

This isn’t a treatment for depression or anxiety, but it is a way to start peeling back the layers and giving the brain what it needs to heal.

The Limits of Medication

Despite $17.4 billion spent annually on antidepressants, 17% of the U.S. population still struggles with mental health.

  • Studies show antidepressants often work no better than placebo for mild depression .

  • Publication bias exaggerates their effectiveness .

  • Antidepressants have been linked to increased risk of suicide, violence, and other side effects .

⚠️ Important: Never stop medication abruptly. Always work with your doctor if considering changes.

Inflammation: The Hidden Driver

Inflammation affects every organ, including the brain. In fact, because the brain is lipid-rich, it may be more vulnerable to inflammatory damage than other tissues.

  • Patients with high C-reactive protein (CRP) often respond poorly to antidepressants and show more cognitive impairment .

  • Inflammation alters brain chemistry, converting serotonin into quinolinic acid, a compound linked to depression and dementia .

  • Triggering inflammation in healthy individuals can actually create symptoms of depression and fatigue .

  • Elevated inflammatory markers are commonly found in people with anxiety and PTSD .

In short, an “inflamed brain” is a depressed brain.

The Microbiome Connection

The gut and brain are deeply linked through the gut–brain axis.

  • SSRIs (antidepressants) can disrupt the microbiome, possibly worsening inflammation .

  • Depressed patients often have a less diverse microbiome compared to healthy controls .

  • Prebiotics and probiotics have shown benefits in reducing depression and anxiety symptoms .

Nutrient Deficiencies That Affect Mood

Most Americans eat a nutrient-poor diet, and certain deficiencies are strongly tied to mental health struggles. Here are a few examples:

  • B vitamins: Low folate, B2, and B6 are linked to depression and more severe symptoms .

  • Vitamin D: Low levels are consistently associated with depression . A simple lab test will tell you if you are deficient.

  • Omega-3 fatty acids (DHA): Deficiency in the brain’s frontal lobe is linked to mood disorders .

  • Magnesium: Supplementation improves mood and reduces symptoms of depression .

  • Thiamin (B1): Deficiency has been found in up to 30% of psychiatric patients . Supplementation has been shown to improve depression and anxiety .

One nutrient that deserves special attention is benfotiamine (a fat-soluble form of thiamin). By improving energy metabolism in the brain, it often helps with mood, cognition, and resilience.

Lithium Orotate: A Trace Mineral With Big Effects

Lithium carbonate (the prescription drug) is very different from lithium orotate, a trace mineral form available as a nutritional supplement.

  • Lithium supports nerve cell protection and helps regulate mood.

  • Studies show low-dose lithium exposure in drinking water is linked with lower rates of suicide and violent crime .

  • Lithium increases proteins (Bcl-2) that protect brain cells from death .

As a gentle, low-dose nutrient, lithium orotate can help stabilize mood and support nervous system balance.

Thyroid and Mental Health

Depression is one of the most common symptoms of hypothyroidism.

  • Undiagnosed or undertreated thyroid conditions increase depression risk .

  • Autoimmune thyroiditis is linked with depression and suicide.

  • Elevated TSH, antithyroglobulin (TgAb), and thyroid peroxidase antibodies (TPOAb) are common in depressed patients.

13 million Americans are hypothyroid and don’t know it. Click here to learn about hidden hypothyroidism.   The usual blood test is TSH, which is incomplete. Click here for a more complete test.

Stress and Cortisol

Long-term stress is not just “in your head”—it chemically changes the brain. High cortisol levels damage the nervous system, promote inflammation, and are strongly tied to both depression and anxiety. Almost everyone with depression or anxiety has high cortisol levels. A simple saliva test can tell you if high cortisol is an issue.

Frequently Asked Questions (FAQ)

1. Can inflammation really cause depression and anxiety?
Yes. Research shows that inflammation affects brain chemistry, reduces serotonin, and increases compounds like quinolinic acid that are linked to depression. Elevated inflammatory markers are often found in people with mood disorders.

2. What nutrients are most important for mental health?
Thiamin (benfotiamine), B vitamins, magnesium, vitamin D, omega-3 fatty acids, and trace minerals like lithium all play important roles in brain energy, mood regulation, and nervous system health.

3. How does the gut microbiome affect mental health?
About 70% of your immune system is in your gut. The microbiome communicates with the brain through the gut-brain axis. An imbalanced microbiome can increase inflammation and contribute to depression and anxiety.

4. What is lithium orotate, and how is it different from prescription lithium?
Lithium orotate is a very low-dose trace mineral form of lithium, available as a nutritional supplement. It is not the same as prescription lithium carbonate used for bipolar disorder. Research suggests low-dose lithium supports mood, protects brain cells, and may reduce aggression.

5. What’s the first step I should take to support my mental health naturally?
Start with an anti-inflammatory diet such as the Roadmap to Health diet. This addresses root causes by lowering inflammation, supporting gut health, and restoring nutrients. Supplements like benfotiamine, lithium orotate, and a high-quality B complex may also help, ideally under the guidance of a doctor trained in natural healthcare.
