Four mechanisms, one of which has a real body of research behind it and three of which are ordinary nutrition. Here is each, and where each one runs out.
JellyRock works through four routes. Acetic acid from the apple cider vinegar complex is the one with a real literature: a 2025 meta-analysis of ten trials found reductions in body weight, BMI and waist circumference at 5 to 30 mL a day, strongest at 30 mL. Vitamin B6, B12 and folate are cofactors in energy metabolism. Iodine is required to make thyroid hormone. Four grams of sugar does what sugar does. No published trial exists on this formula.
There is no human trial on JellyRock Premium Formula. Every study named on this page tested a single ingredient at a stated dose. What is unusual about this product, and worth saying, is that the panel prints enough for the comparison to be meaningful. On most labels in this category it is not.
This is the order we would read any panel in, and this one rewards it.
Apple Cider Vinegar Complex, 1,000 mg. Everything else on this panel is measured in milligrams or micrograms. The largest ingredient tells you what the product actually is, regardless of what the front of the jar says.
Consisting of apple cider vinegar powder providing 5% total acid, and unrefined liquid apple cider vinegar. That bracket is the difference between a number and a dose, and it is where the vinegar question stops being answerable.
Four of the seven percentages on this panel do not match the FDA's published Daily Values. That takes two minutes with the FDA's reference guide and it is worth doing on any label.
Beet root powder, 80 mcg. Pomegranate powder, 80 mcg. Micrograms, not milligrams. This is the line most readers skim past because the eye reads the name rather than the unit.
This is the one part of the panel with a body of evidence behind it, so it deserves to be set out properly rather than summarised into a claim.
In 2025, Castagna and colleagues published a systematic review and meta-analysis in Nutrients pooling ten randomised controlled trials and 789 participants, all of them adults with type 2 diabetes or overweight. Daily intakes ranged from 5 to 30 millilitres, as liquid or as effervescent tablets, over four to twelve weeks.
The pooled results showed significant reductions in body weight, body mass index and waist circumference. They showed no significant effect on waist-to-hip ratio or on fat mass. A dose-response pattern appeared: modest reductions at 5 to 15 mL a day, and the strongest effects at 30 mL.
The authors' own limitations matter as much as the findings. Heterogeneity between studies was high. Intervention durations were short. Risk of bias was mixed. And funnel-plot asymmetry suggested possible publication bias for the body weight and BMI outcomes, which is the statistical signature of negative results not being published.
So: a real, modest, dose-dependent effect in a specific population, from a literature with known weaknesses. That is a fair thing to build a product on, and it is a long way from the front of this jar.
The strongest effects in that analysis were at 30 mL of liquid vinegar a day. One thousand milligrams of a dried complex, of which some unstated fraction is acid, is not 30 mL. If the vinegar is why you are buying, the arithmetic matters more than the format.
Four ordinary nutrients, four ordinary mechanisms, and four amounts you can check.
Folate works in one-carbon metabolism alongside vitamin B12, in DNA synthesis and in red blood cell formation. The form here is 600 mcg of synthetic folic acid, which converts at 1.7 to 1,000 mcg of dietary folate equivalents. The NIH sets a tolerable upper intake level of 1,000 mcg of folic acid a day from supplements and fortified foods, so one serving is 60% of that limit.
Pyridoxine is involved in more than a hundred enzyme reactions, most of them in protein metabolism, and in making neurotransmitters. The RDA for adults 19 to 50 is 1.3 mg, so this is a little over it, and the upper limit is 100 mg a day, so it is nowhere near a concern. Pyridoxine hydrochloride is the most common supplement form.
The only genuinely hormonal ingredient on this label, and it is thyroid rather than testosterone. Iodine is required to make thyroid hormone, which sets the body's metabolic rate. The adult RDA is 150 mcg and the upper limit is 1,100 mcg. Potassium iodide is almost completely absorbed, at about 96% in one NIH-cited study.
Required for red blood cell formation, neurological function and DNA synthesis, and a genuine cause of fatigue when it is short. Two micrograms is a food-level amount rather than a supplement-level one: it is 83% of the FDA's 2.4 mcg Daily Value, not the 100% the panel prints.
The front of the jar reads Masculine Support and Maximum Strength. A marketing panel reads Natural Hormonal Support. It is worth being specific about why the panel cannot carry those.
Testosterone production depends on a set of nutrients that are reasonably well characterised. Zinc deficiency is associated with reduced testosterone. Vitamin D status has been studied in the same territory. Magnesium and boron both appear in the literature. None of the four is on this panel.
The botanicals that appear on products making these claims are also well known: ashwagandha, fenugreek, tongkat ali, maca, tribulus. None of them is on this panel either.
What is on the panel is apple cider vinegar, three B vitamins, iodine and two powders weighing eighty micrograms. There is no plausible route from any of those to a hormonal effect, and we can find no published research proposing one.
That is not a claim that the product is harmful or fraudulent. It is a claim that the words on the front of the jar are not supported by the words on the back of it, which is a thing you can verify yourself in the time it takes to turn a jar around.
Boost energy levels, enhances stamina, supports vitality: these are structure and function claims, which the Dietary Supplement Health and Education Act permits, and they must carry the asterisk and the FDA disclaimer, which the brand's panels do. What no supplement may say is that it treats, cures or prevents a disease. A claim being lawful is not the same as a claim being supported by the panel underneath it.
Every meta-analysis publishes its own weaknesses and almost no product page quotes them. The 2025 apple cider vinegar review reported high heterogeneity, short durations, mixed risk of bias and funnel-plot asymmetry suggesting possible publication bias. Those sentences are part of the finding, not a footnote to it, and leaving them out would make the evidence look tidier than it is.

The acetic acid content of a serving is not published. The 2025 meta-analysis found the strongest effects at 30 mL of liquid vinegar a day.
On dose, no. Thirty millilitres of liquid apple cider vinegar carries far more acetic acid than 1,000 mg of a complex at 5% total acid. On whether you will keep taking it, the gummy wins easily, and a dose you take beats a dose you abandon.
Nothing on the Supplement Facts panel has an established role in testosterone or hormonal regulation. There is no zinc, no vitamin D, no magnesium, no boron and no botanical with hormonal literature behind it. The front of the jar says masculine support; the panel does not support that claim.
We do not know, and it is the oddest line on the panel. Eighty micrograms is eight hundredths of a milligram. Beetroot performance research uses about 500 mL of juice a day, carrying 310 to 682 mg of nitrate. We transcribe the label as printed rather than assuming a units error.
Reviewers who reported noticing anything named three to six weeks, and the seller's own summary lists a slow start among the common complaints. A jar is thirty servings, so a fair trial is two jars rather than one. No published trial exists on this formula.
A question for your doctor rather than for a label. The NIH notes that excess iodine inhibits thyroid hormone synthesis and can produce goitre. 100 mcg is well inside the 1,100 mcg upper limit, but a thyroid condition changes the calculation.
