Fatigue, Brain Fog or Low Mood? It Might Be a Nutrient Deficiency

Fatigue, Brain Fog or Low Mood? It Might Be a Nutrient Deficiency

Do you wake up tired, struggle to focus, or feel flat for no clear reason? Before blaming stress or sleep, you might want to consider something simpler: a nutrient deficiency.

Many essential vitamins and amino acids are involved in mood, energy, and brain function — and when they’re low, your body lets you know.


🔍 Common Symptoms of Nutrient Deficiency

Here are some red flags:

  • Constant fatigue even after rest

  • Mental fog, forgetfulness, or trouble concentrating

  • Low mood, anxiety, or irritability

  • Poor sleep quality

  • Muscle weakness or cramps

  • Pale skin, brittle nails, or hair loss


💡 Key Nutrients That Affect Mood & Energy

  • Vitamin D – for immune health, serotonin, and mood

  • Omega-3 (EPA/DHA) – brain function and inflammation

  • Vitamin B12 – for red blood cell production and nerve health

  • Folate (B9) – mental clarity and methylation

  • CoQ10 – cellular energy (especially for over-40s)

  • Amino Acids – precursors to neurotransmitters like serotonin and dopamine


🧪 How to Test for Deficiencies at Home

We offer easy at-home test kits for:

  • Omega-3 Index

  • Vitamin D

  • CoQ10

  • Vitamin A & E

  • Amino Acids Panel

  • Homocysteine (a marker linked to B12 and folate metabolism)

Simply collect a few drops of blood at home and mail your sample back to our lab.


Stop Guessing, Start Measuring

There’s no need to self-diagnose or waste money on the wrong supplements. A simple blood test gives you clarity — and a roadmap for real change.
