Why Low Amino Acids Affect Mood Thyroid and Energy

Many people choose vegetarian or vegan diets for ethical, environmental, or personal reasons—but few are told about the biochemical consequences that can come with long-term nutrient deficiencies.

In this video, we break down the real connection between vegan and vegetarian diets, amino acid deficiencies, neurotransmitter imbalance, anxiety, depression, and thyroid dysfunction. This isn’t political and it isn’t about judgment—it’s about biology. When the body doesn’t receive enough essential amino acids, it struggles to produce key neurotransmitters that regulate mood, energy, and stress response.

We discuss why people following vegan, vegetarian, or even pescatarian diets often show higher rates of anxiety, depression, fatigue, and hypothyroidism, and how these issues are deeply connected. Low amino acid intake can impact neurotransmitters like serotonin and dopamine, disrupt thyroid hormone production, and create a cascade of symptoms that affect mental health and energy levels.

You’ll also learn why gut health sits upstream of brain health, and how digestive dysfunction can amplify mood disorders when nutrient intake is already compromised. Rather than isolating symptoms, this conversation looks at the body as a fully connected system.

If you’re struggling with anxiety, depression, thyroid issues, or fatigue—and follow a plant-based diet—this video may help you understand what’s really going on beneath the surface.
