Meta Information
ID:hmb
Name:
Schema Version:AIM-2.0
Interactions
Target id:
/intervention/resistance-training
Target name:
Resistance Training
Severity:
major
Interaction type:
synergistic
Nature:
temporal
Temporal spacing:
Hours before target:
1
Hours after target:
null
Description:
HMB reduces muscle protein breakdown and enhances recovery. Peak blood levels occur 1-2 hours post-ingestion, making pre-workout timing ideal to counteract exercise-induced muscle damage and improve adaptation.
Actionable advice:
Take your HMB dose 30-60 minutes before starting your resistance training session for maximal benefit.
Target id:
/intervention/creatine_systemic_healthspan
Target name:
Creatine
Severity:
moderate
Interaction type:
synergistic
Nature:
absolute
Description:
HMB and creatine work via different pathways to improve muscle health; HMB reduces breakdown while creatine enhances cellular energy (ATP), leading to additive benefits in strength, power, and lean mass.
Actionable advice:
Consider taking HMB and creatine together, as they work synergistically to support muscle growth and strength.
Target id:
/intervention/protein
Target name:
Dietary Protein / Essential Amino Acids
Severity:
moderate
Interaction type:
requirement
Nature:
absolute
Description:
HMB signals for muscle protein synthesis and prevents breakdown, but it does not provide the amino acid building blocks itself. Adequate protein intake is necessary to realize HMB's muscle-building benefits.
Actionable advice:
Ensure you consume adequate daily protein from food or supplements for HMB to be effective at building muscle.
Target id:
/intervention/vitamin_d3_systemic_healthspan
Target name:
Vitamin D
Severity:
moderate
Interaction type:
synergistic
Nature:
absolute
Description:
Both HMB and Vitamin D support muscle function and strength, particularly in older adults. Combining them has shown greater benefits for combating age-related muscle loss (sarcopenia) than either alone.
Actionable advice:
Take HMB and Vitamin D concurrently, especially if you are an older adult concerned with muscle health.
Target id:
/intervention/calorie-restriction-diet
Target name:
Calorie Restriction / Dieting
Severity:
moderate
Interaction type:
synergistic
Nature:
absolute
Description:
HMB's primary anti-catabolic effect helps preserve lean muscle mass during periods of caloric deficit, which is crucial for maintaining metabolic rate and strength while losing fat.
Actionable advice:
Supplement with HMB daily when following a calorie-restricted diet to help prevent muscle loss.
Target id:
/intervention/high-intensity-interval-training
Target name:
High-Intensity Interval Training (HIIT)
Severity:
moderate
Interaction type:
synergistic
Nature:
temporal
Temporal spacing:
Hours before target:
1
Hours after target:
null
Description:
Taking HMB before intense training like HIIT can help mitigate muscle damage and soreness, improving recovery between sessions.
Actionable advice:
Take HMB 30-60 minutes before a HIIT session to reduce muscle damage and support recovery.
Target id:
/condition/pregnancy
Target name:
Pregnancy
Severity:
major
Interaction type:
adverse
Nature:
absolute
Description:
The safety of HMB supplementation during pregnancy has not been established. It should be avoided due to unknown effects on fetal development.
Actionable advice:
Do not take HMB if you are pregnant.
Target id:
/condition/lactation
Target name:
Breastfeeding (Lactation)
Severity:
major
Interaction type:
adverse
Nature:
absolute
Description:
It is unknown if HMB is excreted into breast milk or what its effects might be on a nursing infant. Therefore, its use should be avoided during lactation.
Actionable advice:
Do not take HMB if you are breastfeeding.
Target id:
/condition/renal-impairment
Target name:
Renal Impairment
Severity:
moderate
Interaction type:
adverse
Nature:
absolute
Description:
While HMB is generally safe, its clearance may be altered in individuals with significantly impaired kidney function. Caution is advised due to a lack of specific safety data in this population.
Actionable advice:
Consult your physician before using HMB if you have known kidney disease.
Target id:
/condition/hepatic-impairment
Target name:
Hepatic Impairment
Severity:
moderate
Interaction type:
adverse
Nature:
absolute
Description:
The metabolism of HMB in individuals with severe liver disease has not been well-studied. Prudence dictates caution until more safety data is available.
Actionable advice:
Consult your physician before using HMB if you have known liver disease.
Target id:
/dietary/high-protein-meal
Target name:
Large Protein-Rich Meal
Severity:
minor
Interaction type:
diminishing
Nature:
temporal
Temporal spacing:
Hours before target:
0.5
Hours after target:
1
Description:
Taking HMB with a large amount of other amino acids (from a protein meal) may create competition for absorption, potentially slowing its uptake and blunting the peak concentration needed for pre-workout effects.
Actionable advice:
For optimal pre-workout timing, take HMB on an empty stomach or with carbohydrates, not with a large protein shake or meal.
Target id:
/intervention/calcium-citrate
Target name:
Calcium Supplements
Severity:
minor
Interaction type:
synergistic
Nature:
absolute
Description:
HMB is commonly sold as a calcium salt (Calcium-HMB), meaning each dose contributes to your total calcium intake. This should be factored into your overall daily calcium supplementation.
Actionable advice:
Account for the calcium in your HMB supplement when calculating your total daily calcium intake to avoid excess.
