Carnosine is a naturally occurring dipeptide (β-alanine + L-histidine) found in high concentrations in skeletal muscle, brain, and heart tissue. It acts as a pH buffer, antioxidant, and anti-glycation agent that inhibits the formation of advanced glycation end products (AGEs).
Carnosine prevents protein carbonylation and glycoxidation by reacting with carbonyl groups and methylglyoxal before they can damage proteins. It also chelates metal ions, scavenges free radicals, and attenuates aging-induced increases in monoamine oxidase-A (MAO-A) activity in brain regions. In type 2 diabetes, 1 g/day carnosine significantly lowered fasting glucose, triglycerides, carboxymethyl lysine (CML), and TNF-α.
Adults with type 2 diabetes, prediabetes, or those seeking anti-glycation and cognitive protection. Vegan diets are low in carnosine.
No major contraindications. Those with histidine metabolism disorders should avoid. Carnosine is broken down by carnosinase in the bloodstream, so tissue delivery is limited.

Each bar = one cited trial. Effect varies by methodology, dose, and population.
Pre-diabetic cohort (n≈80)
Target HbA1c <6.5% for pre-diabetes management.
54 patients (27 intervention, 27 placebo)
→ 12 weeks of 1 g/day carnosine significantly reduced fasting glucose (13.1 mg/dL), HbA1c (0.6%), triglycerides (29.8 mg/dL), CML (91.8 ng/mL), and TNF-α versus placebo in T2D patients
36 studies (19 in vitro, 15 animal, 2 human)
→ Systematic review of 36 studies found that all but two indicated carnosine can prevent AGE formation. Mechanism includes anti-glycating, anti-carbonyl, and metal-chelating properties
Aged rats (18–24 months)
→ Carnosine (2.0 µg/kg/day, i.t., 21 days) improved cognitive function in radial maze, reduced β-sheet abundance in Aβ secondary structure, and restored spine density in aged rat brain regions
B · One well-designed RCT in T2D showed meaningful metabolic benefits. Strong preclinical anti-glycation and cognitive data. Systematic review supports mechanism but human trials remain few

Who benefits most
Adults with type 2 diabetes, prediabetes, or those seeking anti-glycation and cognitive protection. Vegan diets are low in carnosine.
Dosage and form
500 mg is the typical effective range. Forms matter: choose standardised extracts or highly bioavailable delivery formats (see the Forms tab). Take as directed.
Side effects and cautions
Generally well-tolerated. Avoid if you: No major contraindications. Those with histidine metabolism disorders should avoid. Carnosine is broken down by carnosinase in the bloodstream, so tissue delivery is limited..
The evidence
Human clinical trials and mechanistic research support the use of Carnosine for its primary indication. See the Research tab for full citations and study summaries.
