Meta Information
ID:essential-amino-acids
Name:
Schema Version:AIM-2.0
Interactions
Target id:
/dietary/meal
Target name:
Any Caloric Meal
Severity:
moderate
Interaction type:
diminishing
Nature:
temporal
Temporal spacing:
Hours before target:
0.5
Hours after target:
2
Description:
Consuming EAAs with other protein sources creates competition for absorption, blunting the rapid rise in blood amino acid levels needed to maximally stimulate muscle protein synthesis.
Actionable advice:
Take on an empty stomach, at least 30 minutes before a meal or 2 hours after.
Target id:
/intervention/exercise
Target name:
Exercise
Severity:
moderate
Interaction type:
synergistic
Nature:
temporal
Temporal spacing:
Hours before target:
1
Hours after target:
2
Description:
Taking EAAs near a workout provides readily available building blocks for muscle repair and synthesis when muscles are most sensitive to anabolic signals.
Actionable advice:
For best results, consume within 1 hour before or up to 2 hours after your workout.
Target id:
/class/mtor-inhibitors
Target name:
mTOR Inhibitors
Severity:
major
Interaction type:
diminishing
Nature:
temporal
Temporal spacing:
Hours before target:
12
Hours after target:
12
Description:
Leucine, a key EAA, is a primary activator of the mTOR pathway, while mTOR inhibitors like Rapamycin are designed to block this pathway. Taking them together creates a direct pharmacological conflict.
Actionable advice:
On days you take an mTOR inhibitor like Rapamycin, avoid EAA supplementation or separate the doses by at least 12 hours.
Target id:
/intervention/water-fasting
Target name:
Water Fasting for Autophagy
Severity:
major
Interaction type:
diminishing
Nature:
absolute
Temporal spacing:
null
Description:
Amino acids, especially leucine, are strong activators of mTOR and signal nutrient abundance, which directly inhibits the cellular process of autophagy that fasting is intended to promote.
Actionable advice:
Do not consume EAAs during your designated fasting window if the goal is to maximize autophagy.
Target id:
/intervention/levodopa
Target name:
Levodopa
Severity:
major
Interaction type:
diminishing
Nature:
temporal
Temporal spacing:
Hours before target:
2
Hours after target:
2
Description:
EAAs, particularly the branched-chain amino acids, compete with Levodopa for absorption in the gut and transport across the blood-brain barrier, reducing its effectiveness.
Actionable advice:
Separate Levodopa and EAA doses by at least 2 hours.
Target id:
/condition/renal-impairment
Target name:
Renal Impairment
Severity:
major
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
High doses of amino acids can increase the metabolic burden on compromised kidneys, potentially worsening renal function in individuals with pre-existing kidney disease.
Actionable advice:
Avoid high-dose EAA supplementation if you have significant renal impairment, unless specifically approved by your nephrologist.
Target id:
/condition/phenylketonuria
Target name:
Phenylketonuria (PKU)
Severity:
major
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
Standard EAA supplements contain phenylalanine, an amino acid that individuals with PKU cannot metabolize, leading to its toxic accumulation.
Actionable advice:
Absolutely avoid standard EAA supplements; use only specialized medical formulas designed for PKU.
Target id:
/condition/maple-syrup-urine-disease
Target name:
Maple Syrup Urine Disease (MSUD)
Severity:
major
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
EAA supplements are rich in branched-chain amino acids (leucine, isoleucine, valine), which are toxic to individuals with MSUD who cannot metabolize them.
Actionable advice:
Absolutely avoid EAA supplements; use only specialized medical formulas designed for MSUD.
Target id:
/condition/pregnancy
Target name:
Pregnancy
Severity:
moderate
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
The safety of high-dose EAA supplementation has not been established during pregnancy, and potential effects on the developing fetus are unknown.
Actionable advice:
Avoid EAA supplements during pregnancy unless specifically advised by your physician.
Target id:
/condition/lactation
Target name:
Breastfeeding (Lactation)
Severity:
moderate
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
The safety of high-dose EAA supplementation has not been established during lactation, and it is unknown if components pass into breast milk in high concentrations.
Actionable advice:
Avoid EAA supplements while breastfeeding unless specifically advised by your physician.
Target id:
/intervention/vitamin-b6
Target name:
Vitamin B6
Severity:
moderate
Interaction type:
requirement
Nature:
absolute
Temporal spacing:
null
Description:
Vitamin B6 is an essential cofactor for numerous enzymes involved in amino acid metabolism. Adequate B6 levels are required for the efficient utilization of supplemented EAAs.
Actionable advice:
Ensure adequate Vitamin B6 intake, either through diet or a B-complex supplement, when supplementing with EAAs.
Target id:
/circadian/sleep
Target name:
Going to Sleep
Severity:
minor
Interaction type:
diminishing
Nature:
temporal
Temporal spacing:
Hours before target:
2
Hours after target:
0
Description:
Branched-chain amino acids (BCAAs) in EAA supplements can compete with tryptophan for transport into the brain, potentially reducing the synthesis of serotonin and melatonin needed for sleep.
Actionable advice:
Avoid taking large doses of EAAs within 2 hours of your intended bedtime.
Target id:
/class/antidiabetic-medications
Target name:
Diabetes Medications
Severity:
minor
Interaction type:
adverse
Nature:
absolute
Temporal spacing:
null
Description:
Certain amino acids can stimulate insulin release, which, when combined with diabetes medications, may slightly increase the risk of hypoglycemia (low blood sugar).
Actionable advice:
Monitor blood glucose levels closely when starting EAAs if you are on diabetes medication, especially insulin or sulfonylureas.
Target id:
/intervention/protein-powder
Target name:
Protein Powder (e.g., Whey, Casein)
Severity:
minor
Interaction type:
diminishing
Nature:
temporal
Temporal spacing:
Hours before target:
2
Hours after target:
2
Description:
Taking free-form EAAs simultaneously with a whole protein source like whey is redundant and negates the primary benefit of rapid EAA absorption, as they will compete for uptake.
Actionable advice:
Use EAAs and protein powder at different times; for example, EAAs around a workout and protein powder as a meal supplement.
