What Is in JellyFil? All 9 Ingredients

The panel lists it first, which on a Supplement Facts panel means it is present in the largest amount of the nine — the one thing the ordering of a proprietary blend does tell you. It is a shrub from the Brazilian Amazon whose common name translates as potency wood, and it reaches this gummy on the strength of long traditional use rather than modern trial evidence. What exists: a small, mostly historical human literature and a larger preclinical one. There is no randomised controlled trial of muira puama in men to point a reader at, and saying otherwise would be the easiest lie on this page. NCCIH sets out how to weigh a botanical that sits in exactly this position.

A cruciferous root farmed above 4,000 metres in Peru, eaten there as a food and taken everywhere else as a supplement. Of the nine names on this panel it has the best human trial record. What exists: in a twelve-week double-blind randomised trial (Gonzales 2002, Andrologia), desire scores in healthy men rose from the eighth week onward, and the authors reported that rise with serum testosterone and oestradiol unchanged — worth knowing, since a great deal of category marketing implies the opposite mechanism. A second double-blind study, this time in men with mild erectile dysfunction (Zenico 2009, Andrologia), recorded a modest but statistically significant gain in subjective sexual well-being. A Shin 2010, systematic review pooling the published trials arrived at the same guarded verdict. Every one of those studies dosed maca on its own, at 1,500 to 3,000 mg a day.

Bark from a Brazilian tree. In its own tradition it is seldom taken alone; preparations put it alongside muira puama, and this panel repeats that habit by listing one first and the other third. What exists: preclinical work and traditional use. No randomised human trial of catuaba underpins its place in a vitality formula, and this desk is not going to dress that up. NCCIH is the right starting point for judging an ingredient whose case rests on history.

This one is on the bottle and not in the advertising. Green tea is among the most studied plants in the supplement aisle, and it is also the natural partner to the caffeine declared on the next line, since the two occur together in the leaf. What exists: a review of catechins and the blood vessel (Moore 2009, Br J Nutr) sets out an endothelial route that is genuinely relevant to a circulation claim, and a Peng 2014, meta-analysis of 13 trials put a modest blood-pressure reduction behind ordinary green tea drinking. NCCIH carries the neutral safety summary, including the liver signal attached to concentrated extracts taken on an empty stomach. Those intakes are far above what a shared 82 mg blend can hold, which cuts both ways: the benefit is unlikely at this scale and so is the risk.

The only per-ingredient amount printed anywhere on this product, and the only thing in the gummy with a same-day effect. Five milligrams is a small number. FDA consumer update puts a brewed cup of coffee near 80–100 mg, which makes one gummy about five per cent of a cup — a mouthful of coffee, and a seventh of what sits in a can of cola. It is declared separately rather than folded into the blend, which is the one piece of real transparency on this label. Caffeine-sensitive readers should still note it is there, take the gummy in the morning, and not double up — doubling the gummy doubles the caffeine. It is also the reason the advertising’s silence on this ingredient matters: somebody avoiding caffeine entirely would not learn it from the sales page.

The classical adaptogen of Ayurvedic practice, and alongside maca the best-evidenced name on this panel. It earns its place because for a great many men in their forties and fifties the limiting factor is chronic stress and poor sleep rather than anything a circulation ingredient addresses. What exists: a 2024 systematic review and meta-analysis, Explore pooling randomised controlled trials reported reductions in perceived stress and anxiety, and a 60-day placebo-controlled trial (Lopresti 2019, randomised trial) using a 240 mg standardised extract reported significantly greater falls in morning cortisol than placebo. NIH Office of Dietary Supplements maintains the current professional fact sheet. Worth raising with a prescriber: ashwagandha can interact with thyroid medicine and with sedatives, and case reports of liver injury exist.

The one ingredient here with a mechanism you can draw on a napkin. Arginine is the raw material the body builds nitric oxide out of. Nitric oxide tells the muscle in an artery wall to let go; a wall that lets go widens, and a wider vessel moves blood with less work. That is the whole basis of the circulation claim on the front of the bottle. What exists: the pharmacokinetics have been mapped in detail (Schwedhelm 2008, Br J Clin Pharmacol). Swallowed arginine runs straight into intestinal arginase, which strips out a large fraction of it before any reaches the bloodstream — which is precisely why the quantity matters here and why trials work in grams rather than milligrams. A Khalaf 2019, Nutrients of oral arginine found blood-pressure effects at those intakes. MedlinePlus carries the consumer summary. This is the ingredient behind the medication warnings on this website.

A spiny ground vine used in Ayurvedic and traditional Chinese practice and sold for decades on a testosterone story that its own trial record does not support. What exists: a 2025 systematic review, Nutrients of clinical trials in men found the evidence for erectile function mixed and the evidence for raising testosterone weak; an earlier 2017 trial, Journal of Dietary Supplements in men with unexplained infertility reported no meaningful testosterone change. Naming it is honest; implying it raises testosterone would not be, and this site does not.

The second ingredient on the bottle that the advertising never mentions, and the one with the most interaction literature attached to it. Its active, icariin, is a weak PDE5 inhibitor — the same enzyme family that prescription erectile drugs act on, which is why its omission from the sales copy is the single most consequential gap between the two lists. What exists: laboratory and animal work characterising the erectogenic and neurotrophic effects of purified icariin (Shindel 2010, J Sex Med); MedlinePlus carries the consumer-facing safety entry, including the interaction with nitrates and with blood-pressure medicine. Anyone already prescribed a PDE5 inhibitor should raise this gummy with whoever prescribes it before the first one.
