Urolithin A Supplements Compared: Minus Age 500 mg vs. Cheroline 2000 mg

Urolithin A is a postbiotic compound formed when gut bacteria break down ellagitannins, polyphenols naturally found in pomegranates, walnuts, and berries like strawberries and raspberries. Only a minority of people carry the specific gut bacteria needed to convert ellagitannins into meaningful amounts of Urolithin A, which is why direct supplementation has become the more reliable route to reach research-relevant doses. Two formats stand out for very different reasons: a 500 mg vegan capsule built around a single clinically studied dose, and a 2000 mg softgel that layers in pomegranate, strawberry, and walnut extracts for a broader polyphenol profile.

How Urolithin A Works: Mitophagy Explained

Mitochondria are the energy-producing structures inside every cell, and their efficiency naturally declines with age. Urolithin A activates mitophagy, the cellular quality-control process that tags damaged, underperforming mitochondria for removal, allowing the cell to generate new, more efficient ones in their place. This renewal cycle underlies the compound's reported effects on muscle strength, endurance, and overall cellular energy. Because mitophagy declines with age largely on its own, supplementation is positioned as a way to support a process the body would otherwise slow down.

Minus Age Urolithin A 500 mg — Muscle & Strength Capsules

This product delivers 500 mg of Urolithin A per daily dose in vegan capsules, matching the exact amount used in several landmark clinical trials on muscle strength and mitochondrial health. Each capsule is blister-packed to protect the contents from moisture and light. The formula is built around a single active ingredient rather than a blend, which keeps the dose easy to track.

Ingredient Profile

• Urolithin A — 500 mg per daily dose, delivered via a two-capsule serving in the studied formulation
• Capsule shell: hydroxypropyl methylcellulose (vegan)
• Anti-caking agent: magnesium stearate

What the Research Shows

• A 500 mg daily dose has been linked to a 12% improvement in hamstring muscle strength in clinical research on middle-aged adults
• The same dose has been associated with reduced IL-1β inflammation markers
• Urolithin A supports mitophagy, the process that clears out underperforming mitochondria and prompts the formation of new ones
• Supplementation delivers markedly better absorption than relying on dietary ellagitannins alone, since gut conversion is inefficient in most people

Who it's suited for: Athletes and active individuals who want a clinically dosed, single-ingredient option for muscle recovery and performance. It also suits anyone specifically interested in the muscle-strength research around Urolithin A rather than a broader antioxidant blend.

How to take it: The typical daily serving is two capsules, taken with a sufficient amount of liquid. The recommended dose should not be exceeded, and the product is intended to complement, not replace, a varied diet.

Cheroline Urolithin A 2000 mg — Pomegranate, Strawberry & Walnut Softgels

This formula takes a higher-dose, blended approach. Each softgel combines Urolithin A with pomegranate extract standardized to 40% ellagitannins, organic strawberry fruit extract, and organic walnut shell extract, layering in the natural precursor compounds alongside the active ingredient itself. The softgel format is designed for easier swallowing and is positioned as a 60-day supply per bottle.

Ingredient Profile

• Urolithin A — 2000 mg per serving
• Pomegranate extract — standardized to 40% ellagitannins, the precursor compound Urolithin A is derived from
• Organic strawberry fruit extract
• Organic walnut shell extract
• Softgel shell: gelatin, with vegetable glycerin and purified water

What the Research Shows

• Clinical studies on daily doses in the 1000–2000 mg range report improvements in muscle endurance and a broader panel of inflammatory markers compared with lower doses
• Pomegranate-derived ellagitannins are the natural starting material the body converts into Urolithin A, though conversion efficiency varies widely between individuals
• Higher daily intakes have been studied over periods of up to four months, with a favorable safety profile reported across trials

Who it's suited for: Those looking for a higher-dose option with a wider polyphenol profile from pomegranate, strawberry, and walnut extracts, rather than a single-ingredient formula. The larger bottle size and two-month supply also suit anyone planning a longer, uninterrupted supplementation window.

How to take it: The standard serving is two softgels daily, taken with a meal. The product is not intended for individuals under 18, and the stated daily dose should not be exceeded.
