Lycopene
Lycopene
Lycopene is a naturally occurring red carotenoid pigment found predominantly in tomatoes, watermelon, and other red-pigmented fruits and vegetables. It is widely used as an antioxidant supplement for cardiovascular health, prostate health support, and photoprotection of the skin. Research has focused on its potential role in reducing risk of prostate cancer, atherosclerosis, and age-related macular degeneration.
Mechanism of Action
Lycopene functions primarily as a potent singlet oxygen quencher and free radical scavenger, neutralizing reactive oxygen species that cause oxidative damage to DNA, lipids, and proteins. It modulates cell signaling pathways including inhibition of IGF-1 receptor signaling, upregulation of gap junction communication via connexin proteins, and suppression of pro-inflammatory cytokines such as IL-6 and TNF-alpha. Unlike some carotenoids, lycopene does not convert to vitamin A, and its antioxidant capacity is approximately twice that of beta-carotene on a per-molecule basis.

Dosing Protocols
With a meal containing dietary fat to enhance absorption
Bioavailability is significantly higher from processed tomato products (e.g., tomato paste, sauce) compared to raw tomatoes or synthetic supplements. Doses up to 75mg/day have been used in clinical trials for prostate health without serious adverse effects. Most cardiovascular and prostate health studies used 15-30mg/day.
Safety & Side Effects
Lycopene has an excellent safety profile at recommended doses of 10-30mg/day and is considered safe for long-term use in healthy adults. Unlike beta-carotene, lycopene supplementation has not been associated with increased lung cancer risk in smokers, but caution is still advised at very high supplemental doses in heavy smokers.
Possible Side Effects
- !Lycopenodermia (orange-yellow skin discoloration) with chronic high-dose intake (>30mg/day)
- !Mild gastrointestinal discomfort including nausea or bloating at doses above 30mg
- !Loose stools or diarrhea with very high doses (>75mg/day)
- !Potential lowering of blood pressure, which may cause dizziness in susceptible individuals
- !Rare allergic reactions including skin rash in hypersensitive individuals
Interactions
- -May have additive blood pressure-lowering effects when combined with antihypertensive medications, increasing hypotension risk
- -May enhance anticoagulant effects of warfarin or other blood thinners — monitor INR if used concurrently
- -Concurrent use with other carotenoid supplements (beta-carotene, lutein) may competitively reduce lycopene absorption
- -Cholesterol-lowering drugs such as statins and bile acid sequestrants (e.g., cholestyramine) may reduce lycopene absorption from the gut
- -Orlistat (fat absorption inhibitor) significantly reduces absorption of lycopene and other fat-soluble carotenoids
Cost & Where to Buy
Price varies by dose per capsule, brand quality, and whether sourced from tomato extract vs. synthetic lycopene. Standardized tomato extract products with guaranteed lycopene content tend to cost more than basic supplements.
