Jelly Force Ingredients: the nine names on the Supplement Facts panel

On the panel: first inside the blend, so the largest single share of the 82 mg.

Bark from a small tree in the Brazilian Amazon, used locally as a tonic long before anybody analysed it. A 2018 analysis isolated fourteen compounds from the bark and found the picture is dominated by two alkaloids, magnoflorine and menisperine, which together accounted for about 76% of everything measurable. The phenolic fraction came to no more than 1.04 mg a gram.

That matters for a reader trying to judge an extract: the plant's chemistry is known, and what a given extract actually delivers depends entirely on how it was made, which this label does not state.

For human evidence, there is a gap. A 2020 review of fifteen herbal sexual enhancers covers Ptychopetalum olacoides among them, and its subject is psychiatric and neurological adverse effects rather than efficacy. It concludes that most of the plants reviewed appear safe at therapeutic amounts and that drug interactions are the more serious concern, particularly with unstandardised preparations.

On the panel: second inside the blend, ahead of caffeine, so 5 mg or more.

A root vegetable grown above 4,000 metres in the Peruvian Andes, where it is food rather than a supplement. This is the strongest human evidence on the bottle for desire, and it is worth reading precisely.

A 12-week randomised, double-blind, placebo-controlled trial gave men aged 21 to 56 either 1,500 mg or 3,000 mg of gelatinised maca a day, or placebo. Self-rated sexual desire improved from week eight in the maca groups. The same trial measured serum testosterone and oestradiol and found no difference from placebo, and its authors put that in the title of the paper: the effect they saw had an absent relationship with testosterone.

That single finding is one of the most useful things on this page, because the whole category is sold on a testosterone story. A second trial, a dose-finding study in adults with medication-related sexual difficulty, compared 1.5 g against 3.0 g a day; only the 3.0 g arm separated from baseline on either questionnaire.

Outside this field, a 2024 systematic review and meta-analysis of maca and physical performance in animals and humans reported large effect sizes on fatigue and grip measures, with a dose-response relationship: more macamides, more effect.

On the panel: third inside the blend, ahead of caffeine, so 5 mg or more.

Another Brazilian bark, and one of the fourteen native species that a 2024 review of 74 plants used in Brazilian folk medicine for male sexual dysfunction found with any experimental work behind the tradition. The review is explicit that the evidence base is ethnomedicinal applications and animal models rather than clinical trials.

The laboratory work is real and specific. A 2018 study of the bark's aqueous extract identified and quantified 26 compounds, found that phenylpropanoid-substituted flavan-3-ols make up about 81% of the measured mass, and showed concentration-dependent inhibition of monoamine oxidase A and a mixed inhibition of acetylcholinesterase, both at around 121 micrograms per millilitre.

A concentration in a dish is not an amount in a person, and nothing in the published record tells you what a gummy's worth of this bark does. Naming what the evidence is, rather than implying it is more, is the only honest way to print this ingredient.

On the panel: fourth inside the blend, ahead of caffeine. As the smallest of the four names listed before caffeine it is 5 mg or more and, by the same order, no more than about 19 mg. The advertising leaves it out.

A concentrate of the tea leaf. It brings catechins, the most studied of them EGCG, and a little caffeine of its own. The NCCIH summary of the human research covers body weight, cholesterol and cancer risk, with mixed results, rather than anything on the seller’s list of supports, so no trial amount exists here to set a gummy against.

What is well mapped is its safety. The same summary lists nausea, constipation, abdominal discomfort and raised blood pressure among the side effects of extract supplements, and notes that liver injury, though uncommon, has been reported, mainly with concentrated extracts in tablet or capsule form. A systematic review written largely by scientists at a supplement company found those liver effects tracked the dose, above all large single doses of catechin-rich concentrates, and derived 338 mg a day of EGCG as a safe intake from a solid dose. Even pure EGCG at this ingredient’s bound would be a small fraction of that.

On the panel: fifth inside the blend and the only name with its own amount: 5 mg. The advertising never mentions it.

MedlinePlus puts an 8-ounce cup of coffee at 95 to 200 mg and a cup of tea at 14 to 60 mg. A gummy therefore carries less caffeine than the weakest cup of tea, and about a twentieth of the lowest figure for a cup of coffee.

What caffeine does is better mapped than anything else on this label. A 2025 meta-analysis of 31 randomised, placebo-controlled trials in 1,455 rested adults found it sharpened both reaction time and accuracy on attention tests, and doses of 200 mg and above improved both more than lower ones.

At 5 mg the honest reading is short: it is on the label, it is a stimulant, and it is far below the amounts those trials used. MedlinePlus notes that caffeine raises blood pressure, and the amount here still belongs in the sum for anyone counting their caffeine.

On the panel: sixth, after caffeine, so on the blend rule 5 mg or less.

The most studied herb on the panel by a wide margin, and the only one with a safety literature to match. A 2026 systematic review and meta-analysis of 23 randomised placebo-controlled trials in 1,706 people found oral ashwagandha lowered cortisol, raised serotonin, raised testosterone in men by about 57 ng/dl but not in women, raised T4 modestly, and left TSH, T3 and oestradiol alone.

The trial closest to this product's audience is a 16-week crossover study in overweight men aged 40 to 70 with mild fatigue. Eight weeks of a standardised extract delivering 21 mg of withanolide glycosides a day produced an 18% greater rise in DHEA-S and a 14.7% greater rise in testosterone than placebo. It also found no statistically significant between-group difference in fatigue, vigour, cortisol, oestradiol or sexual well-being — which its own authors say plainly in the abstract.

For fertility specifically, a systematic review of four clinical trials reported large improvements in sperm concentration, volume and motility after 90 days of root extract in men with low sperm counts, with the caveat that only one of the four was randomised.

The safety side belongs beside all of that, not after it. A 2026 scoping review gathered 13 publications describing 25 patients with liver injury attributed to ashwagandha, mostly cholestatic, typically after weeks of use, usually resolving on stopping — but including one transplant and three deaths in people with existing cirrhosis. The LiverTox monograph and the NCCIH summary cover the same ground for a general reader.

On the panel: seventh, after caffeine, so on the blend rule 5 mg or less.

An amino acid, and the ingredient here with the most direct mechanical link to what this product is sold for. The body converts arginine into nitric oxide, the signal that relaxes smooth muscle in a vessel wall and lets the vessel widen.

For blood pressure, a dose-response meta-analysis of 22 randomised trials found oral arginine lowered systolic pressure by 6.40 mmHg and diastolic by 2.64 mmHg on average, across normal and raised baselines alike, with no additional benefit above 9 g a day. A 2026 reassessment using 24-hour ambulatory monitoring in five further trials found reductions in the same direction.

For erectile function, the honest reference point is a network meta-analysis of 15 randomised trials in 1,000 men. It ranked treatments by how reliably they improved the standard questionnaire score. Two carnitines with sildenafil came first, L-arginine with tadalafil second, sildenafil alone third, tadalafil alone fourth, and L-arginine on its own fifth. A separate meta-analysis of three trials in 184 men found arginine combined with pine-bark extract improved several questionnaire domains, and found no difference in testosterone between groups.

Every one of those trials worked in grams.

On the panel: eighth, after caffeine, so on the blend rule 5 mg or less. The advertising leaves it out.

The puncture vine, a low plant of warm, dry ground, and the ingredient in this aisle most often sold as a testosterone booster. That is the part of its story that has not survived. A 2016 review titled Fact or Fiction went through the human and animal record and concluded that the androgen explanation was at best inconclusive and, on the fuller evidence, wrong; it pointed instead to blood-vessel and nitric-oxide mechanisms seen in animal work.

The randomised human evidence is more encouraging than the reputation. A double-blind trial in 180 men aged 18 to 65 with mild or moderate erectile dysfunction gave six 250 mg tablets a day of a concentrated extract — 1,500 mg — for twelve weeks. The erectile-function score rose 2.7 points more than on placebo, side effects were no more common, and one of its authors worked for the extract’s manufacturer. A 2026 meta-analysis of eight trials found the IIEF-5 score about 3.2 points higher than placebo and no difference in total testosterone.

The record is not unanimous. The stricter 2024 network meta-analysis of nutraceuticals found statistically significant effects only for L-arginine and a carnitine combination among the supplements it compared. And the trial amount was 1,500 mg a day, against the 5 mg or less this panel’s order allows.

On the panel: ninth and last, so the smallest share, 5 mg or less. The advertising leaves it out.

Leaves of an Epimedium species, a low woodland plant used in Chinese medicine as a tonic. Its reputation rests on one compound, icariin. A 2008 laboratory study screened plants traditionally used for impotence against human PDE5, the enzyme sildenafil blocks. Of the extracts tested, which included tribulus, only Epimedium’s was active, and icariin inhibited the enzyme with an IC50 of 5.9 micromolar against sildenafil’s 74 nanomolar — roughly eighty times weaker, in a dish.

No randomised human trial of horny goat weed for this use is worth quoting. The safety record is thin in both directions: LiverTox records no link between oral horny goat weed and liver injury, and one published case describes a fast, irregular heart rhythm and hypomania in a man taking a horny goat weed product.

The PDE5 mechanism is the reason it belongs in any conversation about sildenafil, tadalafil or nitrates, and the safety page sets that out.
