Tribulus Terrestris
On both lists, and the clearest case where marketing and evidence diverge.
Tribulus Terrestris in the JellyFil Formula
Label + website
Tribulus terrestris — individual amount not disclosed; part of a single 82 mg proprietary blend.
In one line: Widely sold as a testosterone booster; controlled human trials consistently find that it is not one.
Source note: this is one of only three ingredients that appear on both the product label and the seller’s website.
On both lists, and the clearest case where the marketing claim and the trial evidence point in opposite directions.
What Tribulus Terrestris Is, Before the JellyFil Framing
Tribulus terrestris is a low-growing plant found across warm regions, known in English as puncture vine for its hard spiked seed cases. It has a history of use in both traditional Ayurvedic and Chinese medicine, though generally not for the purpose it is sold for today.
Its characteristic compounds are steroidal saponins, principally protodioscin, and extracts are usually standardised to saponin content.
The word “steroidal” here describes a chemical ring structure, not anabolic activity. This distinction is the source of a great deal of marketing confusion, and it is worth being precise about: these compounds are not anabolic steroids and do not behave like them.
What the Tribulus Research Behind JellyFil Found
This is one of the better-settled questions in sports nutrition, and the answer is not the one the marketing implies.
Testosterone: repeatedly no effect. Multiple randomised, placebo-controlled trials in men — including trained athletes and older men — have found no significant increase in testosterone from tribulus supplementation in men with normal baseline levels. Systematic reviews have reached the same conclusion.
Body composition and strength: no reliable effect. Trials in resistance- trained men have generally found no advantage over placebo.
Where there is something. Some trials have reported improvements in self-reported sexual function or desire, particularly in men with existing difficulties. That evidence is weaker and less consistent, but it is not nothing.
Amounts used: typically 750–1,500 mg a day of a standardised extract.
What Tribulus's Inclusion Means in JellyFil
The seller says tribulus “supports testosterone metabolism, muscular endurance, and the sustained drive that separates peak performance from average effort”.
The testosterone part of that is not supported by the trial evidence, and this is not a marginal or contested finding — it is the consistent result of controlled research over two decades.
The amount compounds it. Studies used 750–1,500 mg; tribulus here shares an 82 mg blend with eight other ingredients, giving roughly 10 mg on an even split — 75 to 150 times below the studied range.
Tribulus is very common in men's supplements precisely because it is cheap and its name carries an association the evidence does not support. Its presence tells you something about how the formula was assembled.
Tribulus Safety in JellyFil
Generally well tolerated at supplemental amounts, with a few points worth knowing.
- Digestive upset is the most commonly reported effect.
- Prostate conditions. Caution is generally advised given the hormonal marketing context, though no clear effect is established.
- Blood sugar. Some evidence suggests tribulus may lower blood glucose; worth mentioning if you take glucose-lowering medication.
- Case reports of liver and kidney injury exist, generally involving very high doses or adulterated products.
- Pregnancy and nursing. Not recommended.
The entire JellyFil blend is 82 mg, shared between nine ingredients
Unusually for this category, no estimate is needed here. The figure is printed on the Supplement Facts panel.
Proprietary Blend: 82 mg. That single number covers muira puama, maca, catuaba, green tea, caffeine, ashwagandha, L-arginine, tribulus and horny goat weed. Caffeine accounts for 5 mg of it, leaving roughly 77 mg shared between eight botanicals — about 10 mg each if divided evenly.
Because it is a proprietary blend, the split is not disclosed. One ingredient could be almost all of the 82 mg and the rest present in trace amounts.
The label's own counter-argument, and why it does not close the gap. The panel adds that 82 mg is “equivalent to approximately 567 mg of dry powders”, meaning concentrated extracts were used. Take that at face value and the even split becomes roughly 63 mg per ingredient — still far below every figure in the right-hand column. L-arginine in particular is studied in grams, and dry-powder equivalence is not the same thing as the standardised extract a trial used.
The honest conclusion: this is a very small amount of active material spread thinly. That is a structural feature of gummies rather than a scandal — a gummy is mostly sugar and pectin, and there is little room for anything else — but it is the fact that matters most when judging whether the formula can do what the page says.
How to read the research described on this JellyFil page
The studies referred to here examined individual ingredients on their own, at the amounts researchers chose — typically hundreds of milligrams, and for L-arginine, grams.
That research explains why an ingredient is of interest. It does not show that JellyFil reproduces those results. No clinical trial of this finished formula has been published, and the entire blend is 82 mg shared between nine ingredients, so the amounts here are far below the ones studied. Nothing on this site estimates the split inside the proprietary blend.

JellyFil Safety Notes
JellyFil safety and sensible precautions
The label's own warning is the right starting point: if you are pregnant or nursing, take medication, or have a medical condition, consult a doctor before use, and stop if any adverse reaction occurs.
- It contains caffeine. Small, but declared — relevant if you are avoiding stimulants for a heart rhythm problem, anxiety, or on medical advice.
- Horny goat weed and blood thinners. Its active compound, icariin, has been reported to have antiplatelet effects. Raise it with a pharmacist if you take anticoagulants.
- Blood pressure medication. L-arginine is a nitric oxide precursor and can lower blood pressure; effects may add together. The amount here is very small, but the interaction is worth knowing.
- Nitrates and erectile dysfunction drugs. Anything acting on nitric oxide pathways deserves a conversation with your doctor if you take nitrates or PDE5 inhibitors.
- Ashwagandha and thyroid or autoimmune conditions. It can raise thyroid hormone levels and stimulate immune activity; there are also case reports of liver injury at higher intakes.
- Green tea extract and the liver. Concentrated extracts have been associated with rare liver injury, generally at far higher amounts than are plausible here.
- Hormone-sensitive conditions. Several ingredients here are marketed around testosterone. If you have a hormone-sensitive condition or take hormone therapy, take medical advice first.
- 3 g of added sugar per gummy — relevant if you manage blood sugar.
- Adults only. Not for anyone under 18, or pregnant or nursing.
JellyFil is a dietary supplement, not a medicine, and is not intended to diagnose, treat, cure or prevent any disease.
What JellyFil is not for
JellyFil is a dietary supplement, not a treatment for any medical condition. It is not a treatment for erectile dysfunction, low testosterone, infertility or prostate disease, and it is not intended to diagnose, treat, cure or prevent any disease.
This matters because the symptoms these products are marketed around often have real, identifiable and treatable causes. Persistent erectile difficulty is a recognised early warning sign of cardiovascular disease — the blood vessels involved are small and are affected first. It can also signal diabetes, low testosterone, thyroid problems, sleep apnoea, depression, or a side effect of medication.
Persistent fatigue likewise has causes worth finding: anaemia, thyroid disease, sleep apnoea, depression, diabetes and vitamin deficiencies among them.
A doctor can test for all of these. A gummy cannot, and buying six months of one instead of getting assessed is the genuinely risky version of this decision.

Read the ingredients page first. The product label and the seller's website describe two different formulas, only three ingredients appear on both, and the label declares caffeine in a product advertised as stimulant-free. Those are the facts that should shape the decision.
