Why Use Supplements for Mental Health?

Before jumping into products, it’s important to understand why supplements matter.

Stress affects your body in multiple ways:

• Raises cortisol (stress hormone)
• Disrupts sleep cycles
• Reduces serotonin and dopamine levels
• Causes brain fog and fatigue

Supplements help by:

• Supporting neurotransmitters (serotonin, GABA)
• Reducing cortisol levels
• Improving sleep quality
• Enhancing brain function

According to research, nutrients like magnesium, omega-3s, and B vitamins play a direct role in stress regulation and brain health.
