What is it and how does it work?Booster Brew
Less energy, less drive, less confidence than before: with age and stress, plenty of men recognise themselves here. Booster Brew is an American dietary supplement that comes not as capsules but as a powdered drink you make every morning.
The 113 g tub is labelled "Maximum Strength" and highlights three areas: performance, libido and drive, and vitality. The official website names six ingredients: a "Nitric Boost Blend" (L-citrulline and L-arginine), horny goat weed (epimedium), Panax ginseng, tongkat ali, beet root powder and a probiotic blend. One tub lasts a month at two scoops a day. The manufacturer adds a flavouring to soften the bitter taste of some ingredients.
None of these ingredients has an authorised health claim in the EU: claims for plants are still "on hold" in the official register1, and the list of authorised claims includes none for them2.
To explain its approach, the sales page tells a long story about an American electrician and an Austrian surgeon, and promises effects on size that we do not repeat: it is a marketing story, and no trial on Booster Brew itself has been published. What can be checked is the formula, and the studies on its ingredients, which we summarise further down.
Let's be realistic: no supplement guarantees results. Age, sleep, diet, exercise and overall health matter a great deal, and every man responds differently.
The formula
Tap an ingredient to learn more. The six ingredients appear in the order of the official website3. The manufacturer does not publish the amount of any of them, so we cannot show how much of each one you get.
- L-citrulline and L-arginine: Two amino acids the body uses to make nitric oxide, a molecule involved in widening blood vessels. The manufacturer refers to a "specific ratio" of the two but does not publish it.
- Horny goat weed: A plant from Chinese tradition, known there as yin yang huo. Its most studied compound is icariin.
- Panax ginseng: Asian ginseng, one of the most widely used plants in Asia for vitality. It is the ingredient with the most trials in men in this formula.
- Tongkat ali: The root of a shrub from Southeast Asia, very common in men's formulas.
- Beet root powder: Naturally rich in dietary nitrates, which the body can convert into nitric oxide. A staple of sports supplements.
- Probiotic blend: Three bacterial strains: Lactobacillus reuteri, Lactobacillus paracasei and Streptococcus salivarius. An unusual choice in this product category. The number of bacteria is not stated.
The official website names six ingredients: a "Nitric Boost Blend" of L-citrulline and L-arginine, horny goat weed (Epimedium), Panax ginseng, tongkat ali (Eurycoma longifolia), beet root powder and a probiotic blend (Lactobacillus reuteri, Lactobacillus paracasei, Streptococcus salivarius), plus a flavouring. No amounts are published.
How to take itOne glass in the morning
Suggested use: two scoops a day, mixed with a glass of water, every morning, for at least 60 days. Do not exceed this amount. A 113 g tub therefore lasts one month. According to the manufacturer the drink is flavoured, so there is no need to mix it into fruit juice.
- Make your drink every morning at the same time
- Stir the powder well into the water
- Eat a varied, balanced diet
- Stay active and get enough sleep
- Close the tub tightly and store it somewhere dry, away from heat
- Keep your expectations realistic
A food supplement is not a substitute for a varied, balanced diet and a healthy lifestyle. The manufacturer describes the drink as a daily ritual and suggests at least six weeks before judging; we do not repeat its promises.
Side effectsIs it safe?
The official website does not list any side effects, and Booster Brew's ingredients are common in supplements. Digestive discomfort, intolerances or allergic reactions are still possible: if that happens, stop taking it and ask a doctor for advice.
A few precautions: arginine, citrulline and beet root can lower blood pressure, and horny goat weed, ginseng and tongkat ali may interact with some medications. If you take medication for blood pressure, your heart (especially nitrates), blood clotting or erections, talk to your doctor before you start. The manufacturer also advises speaking to a doctor if you are pregnant, nursing, taking medication or have a medical condition.
The product is meant for adult men. Booster Brew is not intended to diagnose, treat, cure or prevent any disease, and it is not a substitute for medical advice or prescribed treatment.
Safety and money-back guaranteeCovered for 60 days
According to the refund policy on the official website, every order of 1, 3 or 6 tubs is covered by a 60-day money-back guarantee from the date of delivery. You email customer support with "Refund Request" in the subject line, then send back all the tubs, opened or not, even empty ones, with the packing slip and a note with your name, to the returns address in Ohio (USA).
The refund is processed a few days after your parcel arrives and shows up on your statement within 5 to 10 days. Return postage is paid by the customer.
You pay once on the official website, through the BuyGoods platform. The product is marketed by Prime 2.0 Nutrition and, according to the website, made in a GMP-certified facility. Customer support answers by email and by phone, with a US line and a European line.
Where to buyThe official packs
The safest option is the official website. A product bought elsewhere may not be covered by the guarantee, and there is no way to check where it came from or what is inside.
- The original product
- A 60-day money-back guarantee
- A one-time payment, no subscription
- The total with delivery shown before you pay
Prices as of 21 October 2026, in US dollars, at the official checkout. Delivery to Ireland or the UK costs $19.99 whatever the pack size; your bank may add a currency conversion fee, and import VAT or duty may apply. Prices may change; the official website always shows the current price.
Pharmacy or Amazon?Where you can find it
Many people look for Booster Brew in pharmacies or on Amazon. According to the manufacturer, it is not sold in stores or on Amazon, only on its official website. When we checked on 21 October 2026, Amazon.com showed items under the Booster Brew name, but in other formats than the official 113 g tub, and we could not link them to the manufacturer. The 60-day guarantee only applies to orders placed on the official website.

Is Booster Brew a scam?The facts
The men's supplement market is full of exaggerated promises, and Booster Brew's sales page is no exception: a dramatic story, promises about size and "erections on command". We do not repeat those promises. What matters is what is in the tub: a food supplement with six named ingredients, not a medicine.
Reassuring points
- Sold through BuyGoods, a well-known platform with secure checkout and order tracking
- 60-day money-back guarantee with a written refund procedure
- Customer support by email and phone (US and Europe)
- Well-known ingredients, with scientific references cited for each one
Worth knowing
- The amount of each ingredient is not published
- The sales page promises much more than the studies show
- The references cited are about the ingredients, not about Booster Brew
- Delivery outside the US and return postage cost extra
- Results vary from person to person
Our verdict: Booster Brew is not a scam in the sense of a product that never arrives or an unsafe checkout: ordering, the guarantee and customer support are well organised. It is, however, a food supplement, not a treatment for erectile dysfunction, its formula publishes no amounts and its marketing claims deserve a healthy dose of scepticism. If you want to try it, order from the official website to be covered by the 60-day guarantee, and talk to your doctor if you take any medication.

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: Booster Brew does not state the amount of any ingredient, the studies used their own doses and preparations, several are small, short or done in animals, and some found no effect.
L-citrulline and L-arginine ("Nitric Boost Blend")
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, with 1.5 g of citrulline alone a day; Booster Brew does not state how much citrulline its blend contains.
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 randomised trials with 540 men with mild to moderate erectile dysfunction. Arginine at 1,500 to 5,000 mg a day improved erectile dysfunction compared with placebo or no treatment (odds ratio 3.37).
Limitation: Small trials in men who already had erectile dysfunction, with 1,500 to 5,000 mg of arginine a day; Booster Brew does not state its arginine dose.
Rhim HC, Kim MS, Park YJ, et al. J Sex Med. 2019;16(2):223-234. PMID 30770070 · Read on PubMed
Note: The official website mentions a "specific ratio" of the two amino acids but does not publish it. We cite one study on each amino acid taken on its own.
Horny goat weed (Epimedium)
Randomised, double-blind, placebo-controlled trial in 58 post-menopausal women. 740 mg a day of an Epimedium prenylflavonoid extract for six weeks. No significant adverse effects and no changes in liver, blood or kidney tests were found; bone markers changed only slightly.
Limitation: Studied women and focused on safety; it does not measure male sexual function, and it used 740 mg a day of a concentrated extract, while Booster Brew does not state its epimedium dose.
Yong EL, Cheong WF, Huang Z, et al. Phytomedicine. 2021;91:153680. PMID 34352588 · Read on PubMed
Placebo-controlled crossover trial in 29 men with Gulf War Illness. Epimedium was tested at two doses, each for 30 days. Symptoms did not improve significantly compared with placebo at either dose.
Limitation: Small, specific population and preliminary results; it does not measure sexual function.
Younger J, Donovan EK, Hodgin KS, Ness TJ. Int J Environ Res Public Health. 2021;18(7):3671. PMID 33915962 · Read on PubMed
Note: Human evidence for Epimedium is scarce, and neither study found a positive effect on male sexual function.
Panax ginseng (Asian ginseng)
Cochrane systematic review of 9 randomised trials comparing ginseng with placebo in men with erectile dysfunction. Ginseng had a trivial effect on the erectile function score, may have improved self-reported ability to have intercourse, and caused no more side effects than placebo.
Limitation: The authors rate the certainty of the evidence as low; the trials used different types and doses of ginseng, and Booster Brew does not state its dose.
Lee HW, Lee MS, Kim TH, et al. World J Mens Health. 2022;40(2):264-269. PMID 34169686 · Read on PubMed
Double-blind, placebo-controlled trial in 143 men with erectile dysfunction: 1,000 mg of a tissue-cultured mountain ginseng extract twice a day for 8 weeks. Erectile function and overall satisfaction scores were higher than with placebo.
Limitation: Only 86 of the 143 men completed the trial; it used a tissue-cultured mountain ginseng extract at 2 g a day, and Booster Brew does not state its ginseng dose.
Kim TH, Jeon SH, Hahn EJ, et al. Asian J Androl. 2009;11(3):356-61. PMID 19234482 · Read on PubMed
Tongkat ali (Eurycoma longifolia)
Six-month randomised, double-blind, placebo-controlled trial in 45 men with androgen deficiency of ageing (average age 47). 200 mg of Eurycoma longifolia a day, with or without concurrent training. Erectile function improved in the groups that took the extract and in those that trained; the best result came from training plus the extract.
Limitation: There was no group with the extract alone, so its effect cannot be separated from training; it used 200 mg a day, and Booster Brew does not state its tongkat ali dose.
Leitão AE, Vieira MCS, Pelegrini A, da Silva EL, Guimarães ACA. Maturitas. 2021;145:78-85. PMID 33541567 · Read on PubMed
Randomised, double-blind, placebo-controlled trial in 32 healthy young men. 600 mg a day for two weeks. Total and free testosterone and oestradiol were higher than with placebo; LH and FSH did not change.
Limitation: Two weeks only, small sample of healthy young men, no sexual function measured; it used 600 mg a day, and Booster Brew does not state its dose.
Chan KQ, Stewart C, Chester N, Hamzah SH, Yusof A. Andrologia. 2021;53(4):e14001. PMID 33559971 · Read on PubMed
Beet root powder
Meta-analysis of 118 studies on endurance exercise. Nitrate-rich foods gave a small but significant benefit in endurance performance; among them, beetroot showed benefit. No effect was found in women.
Limitation: The benefit is small and was measured in sport performance tests, not in strength or muscle mass.
d'Unienville NMA, Blake HT, Coates AM, et al. J Int Soc Sports Nutr. 2021;18(1):76. PMID 34965876 · Read on PubMed
Systematic review and meta-analysis of 9 studies (11 trials) with 228 participants. Inorganic nitrate added to exercise training did not improve VO2peak or time to exhaustion more than training alone.
Limitation: Few studies; its result differs from the earlier review on acute performance.
Hogwood AC, Anderson KC, Ortiz de Zevallos J, et al. Sports Med Open. 2023;9(1):84. PMID 37697072 · Read on PubMed
Note: Both reviews measured sports performance; neither measured erections or sexual function, and Booster Brew does not state its beet root dose.
Probiotic blend (L. reuteri, L. paracasei, S. salivarius)
Pilot study in 10 adults aged 50 to 69, who all took the same strain of L. reuteri (ATCC PTA 6475) every day for 12 weeks, with no placebo group. Sex hormones, including testosterone, showed no notable change; body fat percentage, blood pressure and some inflammation markers decreased.
Limitation: Only 10 people, no placebo and one specific strain; Booster Brew does not say which strains it uses or how many bacteria a serving contains.
Noda M, Danshiitsoodol N, Kanno K, Yonezawa S, Ishida R, Sugiyama M. Biosci Microbiota Food Health. 2026;45(1):42-50. PMID 41492377 · Read on PubMed
Study in ageing mice: those given L. reuteri in their drinking water had larger testicles, more testosterone-producing (Leydig) cells and higher blood testosterone than mice of the same age without it.
Limitation: Mice only; the result has not been confirmed in men, and the human pilot study above found no notable change in hormones.
Poutahidis T, Springer A, Levkovich T, et al. PLoS One. 2014;9(1):e84877. PMID 24392159 · Read on PubMed
Note: Both studies concern L. reuteri; we did not find a comparable study on the other two strains in the blend.
