Urolithin A vs NMN: What's the Difference and Should You Take Both?

Urolithin A and NMN are two of the most popular supplements for cellular energy and healthy aging, and people often ask which one to choose. The truth is they work in different ways, and many people take both. This guide compares them side by side.

The short answer

  • Urolithin A supports mitochondrial renewal, helping the body recycle worn-out mitochondria (a process called mitophagy).*
  • NMN is a building block for NAD+, a molecule your mitochondria need to produce energy.*
  • Simply put: Urolithin A helps maintain the engines (mitochondria), and NMN helps supply the fuel system (NAD+).

Side-by-side comparison

Urolithin A NMN
What it is Postbiotic made by gut bacteria from ellagitannins Precursor to NAD+
Main role Supports mitophagy (mitochondrial recycling)* Supports NAD+ levels*
Natural sources Made from pomegranate, walnuts, berries, but only by some people's gut bacteria Small amounts in broccoli, avocado, edamame
Typical studied dose 500–1,000 mg/day 250–900 mg/day
Key human research Muscle strength and endurance measures in middle-aged and older adults Raising blood NAD+; insulin sensitivity in one study of women with prediabetes
Formats Capsules, gummies, softgels Capsules, powder

How Urolithin A works

As we age, the body's ability to clear damaged mitochondria slows down. Urolithin A has been studied for supporting this natural recycling process. Human trials lasting about four months found improvements in muscle strength and endurance measures in middle-aged and older adults taking 500–1,000 mg daily.* Read the full Urolithin A guide.

Only around 30–40% of people make meaningful Urolithin A from food, which is why many choose to take it directly.

How NMN works

NAD+ levels tend to decline with age. NMN is converted into NAD+ in the body, and human studies show oral NMN raises blood NAD+ levels and is well tolerated.* For more, see NAD+ vs NMN vs NR.

Which should you choose?

  • Your focus is muscle, strength and staying active as you age: Urolithin A has the more specific human research on muscle measures.
  • Your focus is overall cellular energy and NAD+ levels: NMN is the more direct choice.
  • You want comprehensive mitochondrial support: taking both covers renewal and fuel supply, two complementary pathways.*

Can you take Urolithin A and NMN together?

Yes. They work through different pathways and there's no known reason they can't be taken together by healthy adults. Many people take both with breakfast. As always, talk to your healthcare professional first if you take medication or have a medical condition.

A simple combined routine:

  • Morning, with breakfast: 500 mg Urolithin A + 500 mg NMN
  • Keep it consistent: both are long-term daily supplements

Frequently asked questions

Is Urolithin A better than NMN?

Neither is "better"; they do different jobs. Urolithin A supports mitochondrial renewal, while NMN supports NAD+ levels.*

Which has more research?

Both have several human trials. Urolithin A research focuses more on muscle measures; NMN research focuses more on NAD+ levels and metabolism.

Should I start with one first?

Some people start with one for a few weeks before adding the other, to see how each fits their routine.

How much of each should I take?
