Pomegranate extract is an inexpensive, well-tolerated source of plant polyphenols. Its best-supported effect is modestly lowering blood pressure, with fairly consistent gains in blood-vessel function, inflammation, and oxidative stress. Cholesterol and blood-sugar effects are mixed. The much-discussed cellular-energy benefits depend on gut bacteria that vary between people. Main drawbacks: mild digestive upset and added blood-pressure lowering. (Full Review)

Protocol

Dose

250–1000 mg/day

Extract standardized to punicalagins (~30%)

Timing

Once daily with food

A meal reduces digestive upset; single daily dose sufficient

Form

Extract or purified urolithin A

Purified urolithin A 500–1000 mg/day bypasses gut-conversion differences

Time to effect

Blood Pressure

4–8 weeks

Most consistent cardiovascular effect

Inflammation & Lipids

4–8 weeks

Develops alongside oxidative-stress markers

Muscle & Mitochondria

Months

Urolithin A–mediated; slower to appear

Benefits

High: Blood pressure reduction

Medium: Improved endothelial and vascular function; reduced inflammatory markers; reduced oxidative stress; improved lipid profile

Low: Glycemic support; cognitive and memory support; exercise performance and recovery

Speculative: Urolithin A–mediated mitochondrial and muscle healthspan; prostate health; skin aging and photoprotection

Contraindications

Pregnancy and breastfeeding

Known pomegranate or tannin allergy

Clinically low blood pressure

Scheduled surgery within ~2 weeks

Key Interactions

Antihypertensive drugs (ACE inhibitors, ARBs, calcium-channel blockers)

Warfarin and other anticoagulants

Statins metabolized by CYP3A4 (simvastatin, atorvastatin, lovastatin)

Other CYP2C9 substrates (glipizide, phenytoin)

Over-the-counter medications (NSAIDs: ibuprofen, naproxen)

Blood-pressure-lowering supplements (beetroot/nitrate, garlic, coenzyme Q10, fish oil)

Risk & Side Effects

Medium: Gastrointestinal discomfort; additive blood-pressure lowering

Low: Drug interactions via liver-enzyme inhibition; allergic reactions

Speculative: Reduced non-heme iron and mineral absorption; high-dose hepatic effects

Monitoring

Marker	Target	Why
Blood pressure	<120/80 mmHg	Pomegranate's most consistent effect
hs-CRP	<1.0 mg/L	Tracks the anti-inflammatory effect
LDL-C	<100 mg/dL (lower if high cardiovascular risk)	Captures any lipid benefit
HbA1c / fasting glucose	HbA1c <5.4%; fasting glucose 75–90 mg/dL	Screens the metabolic effect
Oxidized LDL / PON1 activity (optional)	Higher PON1 activity is favorable	Reflects the antioxidant mechanism

Cadence: Baseline, 8–12 weeks after starting, then every 6–12 months
