Ingredients

Jelly Force Ingredients: Nine Names And What Each One Was Studied At

Jelly Force lists nine ingredients on its Supplement Facts panel: muira puama, maca, catuaba, green tea extract, caffeine, ashwagandha, L-arginine, tribulus and horny goat weed.

All nine sit inside a single 82 mg blend, made from roughly 567 mg of dry powder, and caffeine alone gets its own figure, 5 mg. This page gives each name, what the published work used, and which have no human amount behind them.

The seller’s advertising names five of the nine. This page follows the panel on the bottle, which is both the fuller account and the regulated one.

The formula

The nine names on the Jelly Force panel, and the five in the advertising

The vendor's INSIDE JELLYFORCE tile naming five of the nine panel ingredients around a bottle

The vendor ships an artwork tile, reproduced here, naming muira puama extract, maca extract, catuaba extract, ashwagandha and L-arginine around a bottle, and its footer reads five named ingredients. The seller’s typed list matches it name for name.

Turn the bottle round and the Supplement Facts panel runs to nine. Missing from the advertising: green tea extract, caffeine at 5 mg, Tribulus terrestris and horny goat weed extract. That pattern turns up across this category, and the omitted names are often the better evidenced ones. It holds here: tribulus has the randomised trials and horny goat weed the interaction literature. The panel, as printed, is on the supplement facts page.

Name by name

What each Jelly Force ingredient is, and what the research used

In the order the panel prints them. Eight share the blend; caffeine is the one with its own figure.

Muira Puama Extract

Ptychopetalum olacoidesIn the 82 mg blend

An Amazonian bark, sold in Brazil as marapuama and used there as a tonic rather than as a remedy for one thing.

The published work on this bark is animal work and chemistry. Piato 2010 gave mice 100-300 mg per kilo and found it blunted the anxiety and the raised blood sugar that chronic stress produced, which is a finding about mice under stress rather than about men. A 2024 review of seventy-four Brazilian plants used for male sexual complaints lists the fourteen with pharmacological study behind them, and this bark is not among the fourteen.

Maca Extract

Lepidium meyeniiIn the 82 mg blend

A root vegetable grown above 4,000 metres in the Peruvian Andes and eaten there as food long before it was sold as a capsule.

One of the three best-evidenced names on the panel. A twelve-week randomised trial in healthy men aged 21 to 56 found self-reported sexual desire rose from week eight, at 1,500 mg and 3,000 mg a day, with no change in serum testosterone or oestradiol - the authors checked and said so. A second trial in fifty men with mild erectile difficulty gave 2,400 mg of dry extract for twelve weeks and measured a small but real gain over placebo on the IIEF-5 questionnaire. A dose-finding study in people whose difficulty came from an antidepressant found 3 g a day moved its scores and 1.5 g a day did not.

Catuaba Extract

Trichilia catigua and othersIn the 82 mg blend

A Brazilian bark with a long folk reputation and the loosest botanical definition on the panel.

Catuaba is a trade name rather than a species. Researchers in Vienna bought fourteen commercial catuaba preparations and examined each one: only a minority held the bark their own label claimed, more than half carried other material entirely, and half contained tropane alkaloids at varying strength. Neither the verified Trichilia catigua reference material nor the alkaloid fractions had any effect on rabbit erectile tissue in the laboratory. The 2024 Brazilian review records the same confusion two decades later.

Green Tea Extract

Camellia sinensisIn the 82 mg blend

Tea leaf, concentrated. An extract carries the leaf's catechins, epigallocatechin gallate (EGCG) chief among them, and some of its caffeine, in proportions that vary from one maker to the next.

No trial has tested it against any line this label prints. The human work that matters here is about interactions. Ten volunteers who drank 700 ml of green tea a day for two weeks absorbed about 85% less of the beta-blocker nadolol, and its effect on blood pressure shrank with it (Misaka 2014); one extract drink carrying about 300 mg of EGCG cut exposure to lisinopril by two thirds (Misaka 2021). A USP review ties the rare liver cases to 140 mg to about 1,000 mg of EGCG a day (Oketch-Rabah 2020). This whole blend is 82 mg.

Caffeine

5 mg, printed on the panel

The stimulant in coffee and tea, and the one name on this panel that comes with its own number.

Five milligrams is small. MedlinePlus puts a 6-ounce cup of brewed coffee at 75 to 100 mg and an ounce of dark chocolate at about 10 mg, so a gummy carries about what half an ounce of chocolate does. A systematic review of adverse effects found no overt problems up to 400 mg a day in healthy adults (Wikoff 2017). Green tea extract usually brings some caffeine of its own, and any it carries here sits inside the blend's unsplit share; across nineteen green tea supplements analysed in 2006, only seven gave a caffeine figure at all (Seeram 2006).

Ashwagandha

Withania somniferaIn the 82 mg blend

An Ayurvedic root, and one of the best-known adaptogens on any supplement shelf.

The men's trial worth knowing is a sixteen-week crossover in overweight men aged 40 to 70 with mild fatigue. Against placebo it measured an 18% greater rise in DHEA-S and a 14.7% greater rise in testosterone - and no significant difference at all in fatigue, vigour or sexual well-being, which is the half of that result most supplement pages leave out. Nine randomised trials pooled in 2024 show a consistent effect on perceived stress and on serum cortisol.

L-Arginine

In the 82 mg blend

An amino acid the body converts to nitric oxide, which is the signal that widens a blood vessel.

Ten randomised trials in 540 men with mild to moderate erectile difficulty were pooled in 2019. Arginine beat placebo, with an odds ratio of 3.37, and the doses that did it ran from 1,500 mg to 5,000 mg a day. A 2024 network meta-analysis of fifteen trials ranked L-arginine above every other nutraceutical tested except a carnitine pair, and useful mainly alongside a prescription rather than instead of one.

Tribulus Terrestris

Tribulus terrestrisIn the 82 mg blend

A low, spiny herb of dry ground. The trial with the most weight behind it used a standardised Bulgarian extract sold there as a herbal medicine.

Of the four names the advertising leaves out, the one with the most trial work behind what this label is sold for. In 180 men with mild or moderate erectile difficulty, 1,500 mg a day of dry extract for twelve weeks raised IIEF scores 2.7 points more than placebo, with no difference in side effects (Kamenov 2017). A smaller trial at 800 mg a day for thirty days found no difference at all (Santos 2014). Eight studies pooled in 2026 kept the questionnaire gain and found total testosterone unmoved (Suharyani 2026), as a trial in young men had in 2005 (Neychev 2005).

Horny Goat Weed Extract

Epimedium speciesIn the 82 mg blend

Leaves of Epimedium, a genus used in traditional Chinese medicine as a tonic under the name yin yang huo.

Its marker compound, icariin, inhibits PDE-5 - the enzyme sildenafil and tadalafil act on - in laboratory tests, needing about eighty times sildenafil's concentration for the same effect (Dell'Agli 2008), and it held cGMP up in cavernous smooth muscle cells (Ning 2006). PubMed turns up no randomised trial of the herb on its own; the human trials that include it test multi-herb products. That shared enzyme is why it earns a line on the safety page.

Honest dosage analysis

The amount question, set out in full for Jelly Force

The panel prints one blend figure, 82 mg a gummy, and the footnote puts that at approximately 567 mg of dry powders. Inside the blend, caffeine is listed at 5 mg, so 77 mg is what the other eight names have between them, in proportions the label leaves unsplit.

Ingredient
What the trials used
Where that figure comes from
Muira puama bark
no human amount established
The published work is mouse work at 100-300 mg/kg (Piato 2010) and chemistry. PubMed returns no controlled human trial of the bark alone for sexual function.
Maca root
1,500-3,000 mg a day
Gonzales 2002 ran 1,500 mg and 3,000 mg against placebo for twelve weeks; Dording 2008 found 3 g moved its scores and 1.5 g did not.
Catuaba bark
no human amount established
Kletter 2004 could not even establish which plant fourteen commercial preparations contained, which is a step before any amount can mean anything.
Green tea extract
no trial for this use
The human work is on interactions and safety: Misaka 2021 gave ~300 mg of EGCG and cut lisinopril exposure by two thirds; Oketch-Rabah 2020 ties liver cases to 140-1,000 mg of EGCG a day.
Caffeine
5 mg on this label, the one amount it prints per name
MedlinePlus puts a 6-ounce cup of coffee at 75-100 mg; Wikoff 2017 found no overt adverse effects up to 400 mg a day in healthy adults.
Ashwagandha root
an extract giving 21 mg of withanolide glycosides a day
Lopresti 2019, eight weeks, overweight men aged 40-70. The stress trials pooled by Arumugam 2024 mostly ran 250-600 mg of root extract a day.
L-arginine
1,500-5,000 mg a day
Rhim 2019 pooled ten randomised trials across that range in men with mild to moderate erectile dysfunction.
Tribulus terrestris
1,500 mg of dry extract a day
Kamenov 2017, twelve weeks, 180 men. Santos 2014 gave 800 mg a day for thirty days and found no difference from placebo.
Horny goat weed
no human amount established
Its marker compound, icariin, inhibits the PDE-5 enzyme in the laboratory (Dell'Agli 2008; Ning 2006). No randomised trial of the herb alone turns up.

Read the middle column as a ceiling rather than as a target. Even on the most generous reading, where all 77 mg belonged to one ingredient, it would sit about twenty times below the smallest maca and tribulus amounts in that column and further still below arginine. This is a property of the gummy format rather than a fault in this particular bottle: a chewable is mostly base, and the base is most of the weight.

Four rows in that table carry no human amount for this use, and they are worth separating. Muira puama has an animal literature and a chemistry literature; what it lacks is a controlled human trial of the bark alone. Catuaba lacks something earlier than that, which is agreement about which plant the word refers to. Horny goat weed has laboratory work on its marker compound and no trial of the herb on its own. Green tea extract has human studies, but they measure interactions and safety rather than anything this label claims.

Honest critique

Why the word catuaba is the loose one on the Jelly Force label

In 2004 a group at the University of Vienna bought fourteen commercial catuaba preparations, each labelled as bark of Anemopaegma, Erythroxylum or Trichilia, and examined every one for identity and purity. Only a minority held the crude drug their labels claimed. More than half carried different material altogether. Half contained tropane alkaloids at varying concentrations, and the team elucidated the structures of the two main ones. Then they tested the verified Trichilia catigua reference material, and alkaloid-enriched fractions from the commercial samples, on rabbit corpus cavernosum. Neither did anything (Kletter 2004).

Twenty years later a Brazilian review of seventy-four plants used for male sexual complaints recorded the same thing in one clause: several different species are popularly known as catuaba, leading to adulterations and controversial effects (Teixeira 2024).

None of that is an accusation about this bottle. It is a statement about the word. A reader who wants to know what the catuaba in a given product is has to ask the manufacturer which species and which supplier, and the answer is a sourcing question rather than a label question. Horny goat weed has a milder version of the same issue: the name covers a genus, Epimedium, rather than one species.

What this desk did about it

Asked, and recorded the answer here when there is one. Until then the honest position is that catuaba on this label is a traditional inclusion with a botanical question attached, and the page says that rather than printing a monograph for a species nobody has confirmed.

Scope

What is not in the Jelly Force bottle

Nine names is a middling list by the standards of this aisle, where twelve and eighteen-name blends are common. Length is not the problem so much as the total it is divided by, and the 2023 market analysis that scored twenty-five products (Petre 2023) found that dilution to be the general failure.

Two things a reader might expect and will not find on this panel: yohimbine, which has a genuine pharmacology and a genuine side-effect profile and is absent; and any prescription substance, which is the adulteration risk that has produced eighty synthetic PDE-5 analogues to date (Kee 2018). Caffeine is present, which the advertising leaves unsaid, at 5 mg: well short of the dose some products in this category use to produce a sensation that reads as an effect.
