Adenosine monophosphate

SpecialtyNucleotide

What is it

Adenosine monophosphate (AMP) is a nucleotide consisting of adenine, ribose, and a single phosphate group. It is a key cellular energy molecule and signaling intermediate, and is sometimes included in supplements marketed for energy or immune support.

AI-assisted evidence assessment — talk to your doctor before relying on any single supplement.

Immune support in infants

Limited Evidence

Nucleotide-supplemented infant formulas show some immune-related benefits compared to non-supplemented formulas. Direct evidence for AMP supplementation in adults is limited.

Energy and exercise performance

Mixed Evidence

Despite marketing claims, there is no convincing human evidence that oral AMP supplementation enhances energy or exercise performance.

How it works

Endogenously, AMP is formed from ADP/ATP breakdown and serves as a critical regulator of cellular energy metabolism via AMP-activated protein kinase (AMPK). When cellular energy is low, rising AMP activates AMPK, which shifts metabolism toward energy production and away from energy consumption. Orally ingested AMP is largely broken down to adenosine and ribose by intestinal nucleotidases, then further to adenine and hypoxanthine. Whether oral AMP meaningfully reaches systemic circulation as intact AMP is questionable. Some dietary nucleotide research suggests benefits for immune cell proliferation and gut mucosal integrity, particularly in infants and immunocompromised individuals.

Dosage

No established RDA. Supplemental doses vary widely (50-500 mg/day). Infant formula nucleotide supplementation is typically 50-150 mg/L total nucleotides.

When and how to take it

No specific timing requirements established for supplementation.

2 commercial forms

Compare the main delivery options and what they’re best suited for.

AMP disodium salt

Common supplement form.

Largely degraded in GI tract

Mixed nucleotide blends

Includes AMP, GMP, CMP, UMP; commonly used in infant formula.

Provides multiple nucleotides together

Safety

Generally regarded as safe at typical supplement doses. High doses may increase uric acid production due to purine breakdown. GRAS for use in infant formulas at established levels.

Who should be cautious

People with gout, hyperuricemia, or kidney disease should avoid concentrated nucleotide supplements. Use in pregnancy and lactation is not well studied beyond infant formula contexts.

Interactions

May increase uric acid; caution with gout or hyperuricemia medications. Theoretical interaction with adenosine-related cardiac medications.

Frequently asked questions

Does AMP give you energy?⌄

Inside cells, AMP is part of the energy metabolism system, but taking AMP orally has not been convincingly shown to boost energy levels or exercise performance.

Is AMP the same as cyclic AMP?⌄

No. Cyclic AMP (cAMP) is a distinct second messenger molecule with different functions. They are related chemically but biologically distinct.
