Amino Complex
Description
This essential amino acid complex delivers all nine amino acids the body cannot synthesize on its own, with an emphasis on leucine and the branched-chain amino acids that directly trigger mTOR-mediated muscle protein synthesis. It is designed to support muscle repair and growth whether taken pre-workout, post-workout, or between meals as a protein-sparing supplement. Unlike whole protein sources, free-form amino acids are absorbed rapidly and begin supporting recovery almost immediately. A valuable tool for athletes, active individuals, and anyone seeking to preserve lean mass during caloric restriction.
Effects
First workouts
may reduce soreness slightly
Weeks
supports training adaptation and recovery
Ongoing
most useful when protein intake is low
How it Feels
On its own you will not feel much; the value is in recovery and preserving muscle around training, especially if your overall protein is low. Whole-food protein does most of what this does, so treat it as a convenience tool.
Usage
Entry Dose
5g
Standard Dose
10–15g
Max Dose
20g
Onset
Weeks (training adaptation)
Combinations
Pairs well with
Synergistic
Whey protein isolate — EAAs extend the total amino acid pool; useful around training
Creatine — muscle protein synthesis + phosphocreatine resynthesis post-workout
Vitamin B6 — key cofactor for amino acid transamination and utilization
Avoid combining
Contraindicated
MAOIs — tyrosine and phenylalanine in EAAs can trigger hypertensive crisis
PKU dietary restrictions — phenylalanine-containing aminos contraindicated in phenylketonuria
Biomarkers to Track
Subjective
(Daily)
Recovery soreness next day (1–10)
Muscle fullness during training
Energy during workout (1–10)
Objective
(Quarterly)
Lean body mass (DEXA or scale)
Total protein intake (food log)
Blood urea nitrogen (BUN)
Very safe. Mostly redundant if your protein intake is already high.
People with adequate protein who would get the same benefit from food.
Treating it as essential when whole-food protein does the same job.
