Background/Objectives: The potential influence of lycopene on mental health was indicated in some studies, but it was not summarized within any systematic review so far. The aim of the presented study was to analyze the influence of lycopene on mental health within a systematic review of Randomized Controlled Trials (RCTs). Methods: The study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and it was based on PubMed, Web of Science, Cochrane, and Google Scholar databases, while the RCTs published until February 2025 were included. The systematic review was registered within the database of the International Prospective Register of Systematic Reviews (PROSPERO) (CRD420250650525). The studies were considered where the adult population was studied; intervention was based on oral lycopene intake in any form (lycopene supplement, lycopene-enriched functional food, or regular food product being an important source of lycopene); lycopene intake of a specified dose was applied; any mental health result was studied using a valid psychological measure. After duplicate removal, 642 studies were screened, and finally, six RCTs were included and assessed using the revised Cochrane risk-of-bias tool for randomized trials, while various mental health outcomes were allowed (excluding subjects with intellectual disabilities, eating disorders, and neurological disorders). Each stage of screening, inclusion, reporting, and assessment was conducted independently by two researchers. Results: The included studies were conducted in populations of healthy individuals (one study), but mainly in individuals with various diseases: Benign Prostatic Hyperplasia (BPH) (two studies), Burning Mouth Syndrome (BMS) (one study), xerostomia (one study), and infertility (one study). Within the included studies, various lycopene sources were applied, including lycopene supplements, functional foods, and regular food products, as well as various lycopene doses from 1.35 mg to 27.8 mg per day. The included studies assessed quality of life (five studies), depression and anxiety (two studies), stress (two studies), and mood states (one study). In spite of the fact that all six included studies were RCTs, the comparison between the intervention group and placebo group was made in only four studies, and none of them stated the difference between the compared groups. A low risk of bias was concluded for three studies (all of them not confirming the influence of lycopene on mental health), and a high risk of bias was found in three studies (one of them not confirming, and two not conclusive). Conclusions: The evidence gathered within the systematic review of RCTs did not confirm any influence of lycopene on mental health. Further RCTs are needed to verify the influence of lycopene provided within supplements, functional foods, and regular food products on various mental health problems in diverse populations.

Benign prostatic hyperplasia affects men from the age of 40 and its prevalence increases with age. Millions of men worldwide suffer from this disease, with many of them choosing an alternative treatment approach using phytotherapeutics, which are available in the form of registered preparations or food supplements. These preparations contain extracts that have been tested in clinical studies. Many of these studies have been critically evaluated by systematic reviews and meta-analyses. Recent data shows that saw palmetto (Serenoa repens) has a significant effect. Other drugs used in the treatment of BPH/LUTS include stinging nettle, lycopene, pumpkin, pygeum and rye pollen. However, the results of studies cannot be extrapolated to specific products unless proper extraction techniques, phytochemical analysis and dosage have been followed. The present paper aims to provide an overview of the latest knowledge in the field of BPH/LUTS phytotherapy with an emphasis on the clinical effect, side effects, interactions and rational dosage.
Benigní hyperplazie prostaty sužuje muže již od věku 40 let a její prevalence vzrůstá s věkem. Na světě tímto onemocněním trpí miliony mužů a mnozí z nich volí alternativní léčebný přístup pomocí fytoterapeutik, která jsou dostupná ve formě registrovaných přípravků anebo doplňků stravy. Tyto přípravky obsahují extrakty drog, jež byly testovány v rámci klinických studií. Mnohé z těchto studií byly kriticky vyhodnoceny systematickými review a metaanalýzami. Z dostupných dat plyne, že signifikantní efekt vykazuje serenoa plazivá (Serenoa repens). Mezi další drogy používané v terapii BHP/LUTS patří kopřiva dvoudomá, lykopen, slivoň africká, tykev obecná a žitný pyl. Nicméně výsledky studií nelze extrapolovat do konkrétních produktů, pokud u nich nebyly dodrženy správné extrakční techniky, fytochemické analýzy a dávkování. Tento příspěvek si klade za cíl přehled nejnovějších poznatků z oblasti fytoterapie BHP/LUTS s důrazem na klinický efekt, nežádoucí účinky, interakce a racionální dávkování.

BACKGROUND: Lycopene as a naturally occurring carotenoid is a common part of the human diet. Several beneficial properties of lycopene have been identified, with the most studied being anti-cancer and antioxidant activity. However, no evidence of possible drug-drug or drug-food supplement interactions has been found. METHODS: We studied the in vivo effect of lycopene on the selected rat liver cytochromes P450 (CYPs): CYP1A2, CYP2B, CYP2C11, CYP2C6, CYP2D, and CYP3A. Lycopene was administered to rats intragastrically at doses of 4, 20, and 100 mg/kg/day for 10 consecutive days. Total protein content, P450 Content, and metabolic activity of selected CYPs were evaluated in the rat liver microsomal fraction. RESULTS: Increased CYP2B, CYP2D, and CYP3A metabolic activities were observed in animals treated with the lycopene dose of 100 mg/kg/day. The content of CYP3A1 protein was increased by the dose of 100 mg/kg/day and CYP3A2 protein was increased by all administered doses of lycopene. CONCLUSION: The results of our study indicate that lycopene increased the metabolic activity of enzymes that are orthologues to the most clinically important human enzymes involved in xenobiotic metabolism. The risk of pharmacokinetic interactions between lycopene dietary supplements and co-administered drugs should be evaluated.
