Also known as: Adenosine 5'-triphosphate disodium, ATP supplement, Disodium ATP, Oral ATP
Branded IngredientsEmerging evidence
Oral ATP, sold on the reasonable-sounding premise that supplying the energy molecule improves performance. It does not work the way the name implies, and almost all the research comes from one source.
Typical dose
400.0–400.0 mg per day
30 minutes before training, on an empty stomach
What it is
Adenosine triphosphate is the molecule cells use to store and transfer energy. Peak ATP is a branded, patented form of disodium ATP intended for oral use.
The intuitive assumption is that swallowing ATP raises the ATP inside your muscle cells. It does not. Oral ATP is broken down during digestion and does not cross into cells intact, and the body produces its own ATP constantly in quantities no supplement could approach.
The actual proposed mechanism is different and more interesting: ATP acting outside cells as a signalling molecule. Whether that is worth paying for is the question this entry exists to answer honestly.
How it works
Extracellular ATP acts on purinergic receptors on blood vessel walls and other tissues. Activating these is proposed to promote vasodilation, improving blood flow to working muscle.
There are also proposed effects on muscle excitability and on the recovery of the adenine nucleotide pool after intense effort.
The honest difficulty is that oral ATP is largely degraded before absorption, and studies measuring blood ATP after supplementation have generally not shown meaningful increases. The proposed mechanism requires the compound to reach the relevant receptors, and whether it does at oral doses is not well established.
What the evidence shows
A number of trials have reported improvements in strength, power output and lean mass gains over 8 to 12 weeks of training with 400 mg daily, alongside reduced markers of muscle fatigue.
The significant caveat is that the large majority of this research is funded by or affiliated with the company that produces the branded ingredient, and independent replication is thin. That is not a reason to dismiss the findings, but it is a reason to weight them carefully, and it is a pattern worth recognising across the supplement industry generally.
Given the mechanistic uncertainty and the funding concentration, this is an ingredient where the evidence looks stronger on paper than it does when you examine where it came from.
Dosing
The dose used across essentially all the research is 400 mg daily, taken on an empty stomach roughly 30 minutes before training.
Enteric coating or taking it away from food is standard, on the basis that stomach acid degrades it further.
It is expensive relative to what it delivers. If your budget is limited and the goal is strength and power, creatine monohydrate has overwhelming independent evidence at a fraction of the cost, and that comparison should be made before spending here.

Safety and side effects
Peak ATP has been well tolerated in the trials conducted, with few adverse effects reported. Digestive upset is the occasional complaint.
Safety studies have not identified concerns at the doses used, though as with most branded ingredients those studies come largely from the same source as the efficacy research.
Long-term data beyond the trial durations is limited. Speak to your doctor before use if you take regular medication or are under medical care.
Who should avoid it
Speak to your doctor before use if you take regular medication or are under medical care. Long-term data beyond a few months is limited. Not established at supplemental doses in pregnancy or breastfeeding.
