Metabolic & Nutrient Testing
Protein & Amino Acid Test
Also known as: Amino Acids Analysis
The building blocks of muscle, neurotransmitters, detox, and repair.
Amino acids build muscle, hormones, enzymes, and the neurotransmitters behind mood and focus. Even with plenty of protein, poor digestion, low stomach acid, or high demand can leave you short. This panel shows how well you're digesting protein and supplying your brain and detox pathways.
What it measures
- Leucine, isoleucine, valineMuscle building and recovery.
- Lysine, methionine, threonineTissue repair, collagen, and detox.
- Phenylalanine, tryptophan, histidineRaw materials for brain chemicals.
Who this is for
Helpful when energy, mood, and recovery lag despite a decent diet — especially if you eat little protein or struggle to digest it.
- Fatigue or slow recovery
- Low mood, anxiety, or poor focus
- Muscle loss or weakness
- Slow wound healing
- Plant-based or low-protein diet
- Bloating after protein-rich meals

How we interpret it
We read every panel through a functional lens — optimal reference ranges, ratios, and cross-panel patterns. Results become part of your written Root Cause Report and your personalized 12-week protocol.
We use your amino acid pattern to fine-tune protein intake and digestion support — minerals like zinc are needed to make stomach acid, so this often ties back to your HTMA.
Often paired with
Candida, Metabolic & Vitamins Test
Yeast, bacteria, mitochondrial energy, neurotransmitters, oxalates, and vitamin needs — from one urine sample.
Zinc & B6 Depletion Test
A urine marker linked to zinc and vitamin B6 loss — and the stress, anxiety, and mood patterns that follow.
Mood & Mind Neurotransmitter Test
The calming and energizing brain chemicals behind mood, focus, motivation, and sleep.
