AICAR Benefits
- ✓Increases endurance capacity, enhances fatty acid oxidation, promotes mitochondrial biogenesis, improves glucose uptake, cardioprotective effects
hBD-1 Benefits
- ✓oral innate immunity
- ✓broad antimicrobial activity
- ✓biofilm suppression
- ✓periodontal support
AICAR Dosing
Research doses: 50-150 mg subcutaneously. Typically administered 30-60 minutes before physical activity in research settings.
hBD-1 Dosing
topical peptide exposure|cell-culture or mucosal models|repeat low-dose application in research
AICAR Side Effects
- ⚠Potential hypoglycemia, lactic acidosis at high doses, injection site reactions. Banned by WADA as a metabolic modulator.
hBD-1 Side Effects
- ⚠protease degradation
- ⚠local irritation at high dose
- ⚠limited stability in saliva
Research Overview
AICAR
Salk Institute researchers demonstrated AICAR could increase endurance in sedentary mice by 44% without exercise training. Activates AMPK, triggering PGC-1α expression, mitochondrial biogenesis, and enhanced fatty acid β-oxidation.
hBD-1
hBD-1 has been studied as part of the oral mucosal defense system and is linked to host resistance against dental pathogens. Research spans periodontitis, candidiasis, and epithelial barrier biology.
