What is it and how does it work?Virdexis
Work, family, short nights: many men feel less energetic than they used to and look for a little help. Virdexis is a dietary supplement in capsules, presented on its bottle as men's support for "testosterone, male stamina and healthy circulation".
Each bottle holds 30 capsules, and the recommended dose is one capsule a day, so one bottle lasts a month. The formula combines two amino acids (L-citrulline and L-carnitine), two polyphenol-rich extracts (maritime pine bark and grape skin), maca root, saffron, niacin (vitamin B3) and zinc. According to the official website, it is made in the EU from ingredients of natural origin.
Two ingredients have authorised EU health claims at the dose in Virdexis: zinc contributes to the maintenance of normal testosterone levels in the blood, and niacin contributes to the reduction of tiredness and fatigue2. Claims for plants are still "on hold" in the official register1.
That is why we do not repeat the promises on the website ("ab heute Abend", from tonight): no study has been published on Virdexis itself. What can be checked is the formula, and the studies on its ingredients, which we summarise further down.
Let's be realistic: no capsule replaces sleep, a varied diet and physical activity. Age, overall health and lifestyle matter far more, and every person responds differently.
The formula
Tap an ingredient to see its dose. The nutrition table on the official website gives the amount of each ingredient for the daily dose of one capsule3. For zinc and niacin it also gives the % of the nutrient reference value (NRV4); plants and amino acids have none.
- Vitamin B3 (niacin) – 20 mg: Niacin contributes to the reduction of tiredness and fatigue and to normal energy-yielding metabolism (claims authorised in the EU).
- Zinc (zinc oxide) – 11 mg: Zinc contributes to the maintenance of normal testosterone levels in the blood and to normal fertility (claims authorised in the EU).
- L-citrulline – 150 mg: An amino acid found in watermelon, among other foods. The body converts it into L-arginine, which is used to make nitric oxide.
- L-carnitine – 150 mg: A compound the body uses to turn fat into energy, common in "energy" formulas.
- Maritime pine bark extract – 100 mg: From the bark of the maritime pine, a source of polyphenols, plant compounds with antioxidant properties.
- Maca root extract – 50 mg: A plant from the Peruvian Andes, long eaten as a food there and widely used in men's supplements.
- Grape skin extract – 15 mg: From the skin of the grape, also rich in polyphenols.
- Saffron stigma extract – 5 mg: Made from the stigmas of the saffron crocus, one of the most precious spices in the world.
Nutrition table according to the official website, per capsule: vitamin B3 (niacin) 20 mg (125% of the NRV), zinc (zinc oxide) 11 mg (110% of the NRV), L-citrulline 150 mg, L-carnitine 150 mg, maritime pine (Pinus pinaster) bark extract 100 mg, maca (Lepidium meyenii) root extract 50 mg, grape (Vitis vinifera) skin extract 15 mg, saffron (Crocus sativus) stigma extract 5 mg. The website does not list the capsule shell or other excipients. 30 capsules per bottle.
Dosage and useOne a day
According to the official website, take 1 capsule a day, for example in the evening with a large glass of water. A bottle of 30 capsules therefore lasts a month. Never exceed the recommended daily dose.
- One capsule a day, with a glass of water
- At the same time every day, so you don't forget
- Do not exceed the recommended daily dose
- Keep the bottle tightly closed, dry and away from light
- Eat a varied, balanced diet
- Keep it out of the reach of children
Dietary supplements are not a substitute for a varied, balanced diet and a healthy lifestyle.
Side effectsIs it safe?
The official website lists no known side effects when Virdexis is used as directed, and its ingredients are common in dietary supplements. Digestive upset, an intolerance or an allergic reaction are still possible: if that happens, stop taking it and ask a doctor for advice.
Niacin can cause flushing in some people; at 20 mg per capsule this is uncommon. Virdexis is for adults only (not under 18). The website recommends asking a doctor before use, especially if you take medication or have a medical condition.
Saffron and L-citrulline can interact with some medicines (antidepressants, blood pressure medicines or nitrates): if you take medication, talk to your doctor first. Virdexis is not intended to diagnose, treat, cure or prevent any disease.

Is Virdexis a scam?The facts
Before buying a "male vitality" supplement online, it makes sense to look closely at the offer. The market is full of exaggerated promises. What matters is what is in the bottle: a dietary supplement, not a medicine.
What is reassuring
- The dose of all 8 ingredients is published
- Identified platform and seller, written return terms
- One-time purchase with no subscription and well-known payment methods
- Zinc and niacin at doses recognised by the EU
Good to know
- Refunds apply to unopened bottles only
- Delivery limited to Germany, Austria and Switzerland
- No study has been published on Virdexis itself
- Results vary from person to person
Our verdict: Virdexis is not a scam in the sense of a product that never arrives or an unsafe payment: the shop is identified, payment is one-time and the full formula is published. But it is a dietary supplement, not a treatment, and it does not replace a balanced diet, exercise or medical advice. If you want to try it, order from the official website and keep the bottles sealed until you are sure, because only unopened bottles are refunded.

Studies cited
For each ingredient, we list two studies found in the scientific literature. The summaries describe what each study measured and found. They do not promise results: most of these studies are small or short, used doses different from those in Virdexis, and some found no effect.
L-citrulline
Single-blind study in 24 men with mild erectile dysfunction (average age 56): one month of placebo, then one month of 1.5 g of L-citrulline a day. Erection hardness reached the normal score in 12 of 24 men with L-citrulline, against 2 of 24 with placebo.
Limitation: Small study, not randomised, one month only; 1.5 g a day is ten times the 150 mg of L-citrulline in a Virdexis capsule.
Cormio L, De Siati M, Lorusso F, et al. Urology. 2011;77(1):119-22. PMID 21195829 · Read on PubMed
Systematic review and meta-analysis of 10 placebo-controlled studies on citrulline and aerobic exercise. Citrulline did not improve aerobic performance, perceived exertion, oxygen uptake or lactate.
Limitation: Negative result for performance; the studies used several grams of citrulline a day, far more than the 150 mg in Virdexis.
Viribay A, Fernández-Landa J, Castañeda-Babarro A, et al. Nutrients. 2022;14(17):3479. PMID 36079738 · Read on PubMed
L-carnitine
Randomised, placebo-controlled trial in 120 men aged 60 to 74 with symptoms of male ageing, over six months. Propionyl-L-carnitine plus acetyl-L-carnitine (2 g each a day) improved erectile function scores, mood and fatigue compared with placebo; testosterone levels did not change.
Limitation: It used other forms of carnitine (propionyl- and acetyl-L-carnitine), 4 g a day in total: more than 25 times the 150 mg of L-carnitine in Virdexis. The effect faded after stopping.
Cavallini G, Caracciolo S, Vitali G, Modenini F, Biagiotti G. Urology. 2004;63(4):641-6. PMID 15072869 · Read on PubMed
Randomised, double-blind, placebo-controlled trial in 66 centenarians with fatigue after slight physical activity. 2 g of L-carnitine a day reduced physical and mental fatigue and increased muscle mass compared with placebo.
Limitation: Very specific population (people over 100); 2 g a day is more than 13 times the 150 mg of L-carnitine in Virdexis.
Malaguarnera M, Cammalleri L, Gargante MP, et al. Am J Clin Nutr. 2007;86(6):1738-44. PMID 18065594 · Read on PubMed
Maritime pine bark extract
Randomised, double-blind, placebo-controlled crossover trial in 50 men with mild to moderate erectile dysfunction. One month of a combination of French maritime pine bark extract (Pycnogenol) and L-arginine aspartate. Erectile function and intercourse frequency improved, and blood testosterone rose.
Limitation: The extract was combined with L-arginine, which Virdexis does not contain, so this study says nothing about pine bark on its own; short study with diary-based outcomes.
Stanislavov R, Nikolova V, Rohdewald P. Int J Impot Res. 2008;20(2):173-80. PMID 17703218 · Read on PubMed
Randomised, blinded, placebo-controlled study in 53 men with erectile dysfunction, 32 of them with diabetes, over three months. Pine bark extract (Pycnogenol) alone improved erectile function scores (IIEF-5) and lowered cholesterol; placebo had no effect.
Limitation: Small study with a specific branded extract (Pycnogenol); the PubMed summary does not give the dose, so it cannot be compared with the 100 mg of pine bark extract in Virdexis.
Trebaticky B, Muchova J, Ziaran S, et al. Bratisl Lek Listy. 2019;120(12):941-944. PMID 31855055 · Read on PubMed
Maca root extract
Randomised, double-blind, placebo-controlled trial in healthy men aged 21 to 56, over 12 weeks. 1,500 mg or 3,000 mg of gelatinised maca. Self-reported sexual desire improved from week 8; testosterone and oestradiol did not differ from placebo.
Limitation: Self-reported outcome; 1.5 to 3 g of maca a day is 30 to 60 times the 50 mg of maca extract in Virdexis (the official nutrition table does not give the extract ratio).
Gonzales GF, Córdova A, Vega K, et al. Andrologia. 2002;34(6):367-72. PMID 12472620 · Read on PubMed
Randomised, double-blind, placebo-controlled trial in 80 men with late-onset hypogonadism symptoms and normal testosterone. 1,000 mg three times a day for 12 weeks. Scores for ageing-male symptoms, erectile function (IIEF) and urinary symptoms (IPSS) improved more than with placebo.
Limitation: Questionnaire-based outcomes; 3 g a day is 60 times the 50 mg of maca extract in Virdexis.

Vitamin B3 (niacin)
Randomised, placebo-controlled trial in 160 men with erectile dysfunction and high blood lipids, over 12 weeks, with up to 1,500 mg of niacin a day. Erectile function improved in men with moderate or severe dysfunction; there was no improvement in mild cases.
Limitation: Pharmacological dose of up to 1,500 mg a day, about 75 times the 20 mg of niacin in a Virdexis capsule; the placebo group also improved.
Ng CF, Lee CP, Ho AL, Lee VW. J Sex Med. 2011;8(10):2883-93. PMID 21810191 · Read on PubMed
Population study of 3,184 American adults (NHANES 2001-2004). Men with the highest dietary niacin intake were less likely to report erectile dysfunction than those with the lowest intake.
Limitation: Observational study, not a trial: it shows an association, not cause and effect, and it looked at niacin from food, not from supplements like Virdexis.
Lin WL, Zheng C, Wang HX, Zhang W, Lin ME. Asian J Androl. 2024;26(4):382-388. PMID 38305697 · Read on PubMed
Grape skin extract
Randomised, double-blind, placebo-controlled crossover trial in 24 men with metabolic syndrome. 30 days of a freeze-dried grape polyphenol powder lowered systolic blood pressure and improved the dilation of the arteries (flow-mediated dilation).
Limitation: Whole-grape powder, not a skin extract, and it measured blood vessels, not sexual function or energy; Virdexis contains 15 mg of grape skin extract.
Barona J, Aristizabal JC, Blesso CN, Volek JS, Fernandez ML. J Nutr. 2012;142(9):1626-32. PMID 22810991 · Read on PubMed
Randomised, placebo-controlled trial in 66 middle-aged men with metabolic syndrome, over four months. Resveratrol, a polyphenol found in grape skin, at 150 mg or 1,000 mg a day, did not change testosterone, free testosterone or DHT.
Limitation: Negative result; it tested isolated resveratrol, not grape skin extract. The whole 15 mg of grape skin extract in Virdexis is a tenth of the lower resveratrol dose studied.
Kjaer TN, Ornstrup MJ, Poulsen MM, et al. Prostate. 2015;75(12):1255-63. PMID 25939591 · Read on PubMed
Zinc
Study in healthy men. Restricting dietary zinc for 20 weeks lowered testosterone in 4 young men, and three to six months of zinc in 9 older men with a marginal deficiency raised it.
Limitation: Very small groups without placebo; the effect concerns men with a zinc deficiency. A Virdexis capsule provides 11 mg of zinc (110% of the NRV).
Prasad AS, Mantzoros CS, Beck FW, Hess JW, Brewer GJ. Nutrition. 1996;12(5):344-8. PMID 8875519 · Read on PubMed
Study in 14 healthy, active men aged 22 to 33 with enough zinc in their diet. A high-dose zinc supplement raised blood zinc but did not change total or free testosterone.
Limitation: Negative result in men without a deficiency; small group, and a high-dose supplement, above the 11 mg of zinc in Virdexis.
Koehler K, Parr MK, Geyer H, Mester J, Schänzer W. Eur J Clin Nutr. 2009;63(1):65-70. PMID 17882141 · Read on PubMed
Saffron extract
Randomised, double-blind, placebo-controlled trial in 36 men whose antidepressant (fluoxetine) affected their sex life. 15 mg of saffron twice a day for four weeks improved erectile function and intercourse satisfaction more than placebo; desire and orgasm did not differ.
Limitation: Small, four-week study in a specific group (men taking fluoxetine); 30 mg a day is six times the 5 mg of saffron extract in Virdexis.
Modabbernia A, Sohrabi H, Nasehi AA, et al. Psychopharmacology (Berl). 2012;223(4):381-8. PMID 22552758 · Read on PubMed
Randomised, open-label crossover study in 346 men with erectile dysfunction. 30 mg of saffron twice a day for 12 weeks brought no significant improvement in erectile function scores; the authors concluded the results do not support a benefit of saffron.
Limitation: Negative result in a large study; it was open-label and compared saffron with sildenafil, without a blinded placebo. 60 mg a day is 12 times the 5 mg of saffron extract in Virdexis.
