How Maxforce Works: The Formula Behind the Claims
What Maxforce is sold to do, set beside what NCCIH, NIH ODS and MedlinePlus actually publish — including both tribulus trials rather than one of them.
Written and reviewed by the Maxforce Editorial Desk · Last updated October 29, 2026
Quick answer
Maxforce is sold as a daily gummy for vitality, drive and performance.
One gummy a day delivers nine ingredients in one 82 mg blend, and each label claim is marked with an asterisk.
3 claims on the jar
What the product is sold to do
Three hedged claims on the label, three stronger ones on the sales page, one mechanism underneath both.
The jar prints three hedged claims — May Support: Vitality*, Drive*, Performance* — each asterisked to a disclaimer in its own ruled box. The sales copy supplied with the pack is less careful, and says the product will “naturally and effectively support sexual health”, “increase vitality and energy” and “promote healthy blood circulation”.
Underneath both sits a mechanism worth stating fairly before it is tested: botanical extracts with a long history of traditional use, an amino acid the body converts into a vasodilator, a small declared amount of caffeine, and an adaptogen with a real clinical literature behind it. That is a coherent story. This page asks what the federal record holds on it, and then asks the question that decides the answer: how much of each is in the gummy?
1 sentence, and it is the spine
NCCIH’s verdict on this category, in one sentence
Printed once, plainly, near the top — because that is where it belongs.
This product is sold under two words printed on its own jar: male enhancement. There is a federal page about that category specifically, and it is the plainest sentence on this site. NCCIH: “No complementary health approaches have been shown to be safe and effective for sexual enhancement or treating erectile dysfunction (ED).” And: “Currently, there is no definite evidence that any herbal products are effective or safe for ED.”
That sentence is the spine of this page and it is not a hostile one. NCCIH is not saying these plants are dangerous, and it is not saying nobody has studied them. It is saying that across the whole family of complementary approaches sold for this purpose, none has been shown to be both safe and effective for it. The honest thing to do with a sentence like that is print it once, plainly, near the top.
2 trials, opposite results
Both tribulus trials, and the row they sit in
One positive in 2017, one null in 2014, and a row capped at 5 mg.
Fairness cuts both ways, and one ingredient here has a positive randomised controlled trial attached to it. NCCIH reports it: “A 2017 prospective, randomized controlled trial in 86 men with mild to moderate ED found that following a 12-week treatment of extracts of the plant Tribulus terrestris, significant improvement in sexual function was observed with Tribulus terrestris compared with placebo.”
And immediately alongside it, on the same page: “An earlier study (2014) conducted in 30 men with ED found that Tribulus terrestris was not more effective than placebo on improving symptoms of ED or serum total testosterone.”
Both belong on this page and neither belongs on it alone. A positive twelve-week trial in 86 men is a real result; an earlier null trial in 30 men is a real result too; and NCCIH, having read both, draws its own conclusion in the sentence at the top of the same page.
Then the arithmetic that decides whether either trial is relevant to this jar. Tribulus terrestris is row eight of nine, listed below the printed 5 mg caffeine row, so it can be no more than 5 mg. The 2017 trial ran twelve weeks on extracts at a research amount. A trial result does not travel down to an amount the trial did not use.
6 of nine, and capped at 5 mg
Ashwagandha, and what its testosterone note is about
A real finding, about fertility markers, at amounts this panel does not reach.
Ashwagandha is the other one with something behind it, and again the detail matters. NCCIH: “There is some limited evidence that suggests that taking ashwagandha for 2 to 4 months may increase testosterone levels and sperm quality.” That is about testosterone and sperm — fertility markers — not erection, not libido and not performance. NCCIH’s own effectiveness verdict for ashwagandha names two conditions and neither is sexual: “Research shows that some ashwagandha preparations may be effective for insomnia and stress.” Ashwagandha is row six of nine here, capped at 5 mg.
The distinction there is the one most easily lost. Testosterone level and sperm quality are fertility markers: measured in blood and in semen analysis, and the outcomes of a fertility study. They are not erection, not libido and not performance, and a finding about one is not a finding about the others. Anyone whose actual question is about fertility should be having it with a clinician who can order the tests.
5 mg, against a gram-scale range
Nitric oxide, and the row that is supposed to deliver it
The mechanism the category leans on hardest belongs to L-arginine, and NIH ODS states it without argument: “First, some arginine is converted to nitric oxide, a potent vasodilator that can increase blood flow and the delivery of oxygen and nutrients to skeletal muscle.” That is real physiology. Two things qualify it here.
The first is the setting: ODS is writing about skeletal muscle during exercise, in a fact sheet for health professionals. Nothing in it concerns sexual function. The second is the conclusion ODS reaches after describing the mechanism: “The research to support supplemental arginine as a performance enhancer is limited and conflicting. Overall, it suggests that doses of 2–20 g/day arginine have little to no effect on performance in either anaerobic or aerobic exercise.”
L-arginine is row seven, so no more than 5 mg — a four-hundredth of two grams. The mechanism is sound; the quantity is not in the same conversation as the research. Green tea extract, row four, is the other row with a federal page, and NCCIH does not commit on it either: “Although many studies have been done on green tea and its extracts, definite conclusions cannot yet be reached on whether green tea is helpful for most of the purposes for which it is used.”
4 steps, in the order FDA words them
One piece of category context, in FDA’s order
One piece of category context belongs here, and it needs giving carefully rather than leaving out. FDA publishes notifications about supplements sold for sexual enhancement that were found to contain undeclared prescription drug ingredients, and describes such products as “These products are typically promoted for sexual enhancement, weight loss, pain relief and body building and are often represented as being all natural.” A search of FDA’s Sexual Enhancement and Energy Product Notifications on September 25, 2026 did not return Maxforce. That is a statement about what a database contained on a date, and nothing more. FDA’s own caveat belongs immediately beside it: “FDA is unable to test and identify all products marketed as dietary supplements that have potentially harmful hidden ingredients.” And FDA’s own advice closes it: “Talk to a health care professional before buying or trying a new product for your health.”
Nothing in that paragraph is a clearance, and no supplement receives one: “Under DSHEA, FDA does not have the authority to approve dietary supplements before they are marketed.”
3 sentences from MedlinePlus
What the record suggests doing instead
There is a more useful answer than any of this, and MedlinePlus gives it in three sentences. “ED can be a sign of health problems. It may mean your blood vessels are clogged. It may mean you have nerve damage from diabetes.” “If you don’t see your doctor, these problems will go untreated.” And: “Some people have trouble speaking with their doctors about sex. But if you have ED, you should tell your doctor.” Difficulty can be the presenting sign of a vascular or metabolic problem that is treatable, and treating it is better than covering it. MedlinePlus adds that “Getting more exercise, losing weight, or stopping smoking may also help.”
None of that makes this product dishonest, and the label deserves its credit in the same voice as the criticism. The jar hedges its claims with “May Support”, asterisks all three and resolves the asterisk to the FDA disclaimer in a ruled box. It itemises its caffeine at 5 mg rather than hiding it in the blend total. It names a distributor with a city, a state, a ZIP and a phone number. Those are the choices of somebody who read the rules.
So the honest summary is two sentences long. The mechanism this product is sold on is a real mechanism, studied at amounts between forty and four thousand times what this panel permits. And the federal agency that reviews the whole category has looked at it and written one sentence, which this page has already printed.
Questions
Maxforce FAQ: how it works questions
Does any federal page support these ingredients for sexual performance?
No. NCCIH is direct: “No complementary health approaches have been shown to be safe and effective for sexual enhancement or treating erectile dysfunction (ED).” And: “Currently, there is no definite evidence that any herbal products are effective or safe for ED.”
Is there anything positive at all?
Two things, and both come with conditions. NCCIH cites a 2017 randomised trial in 86 men where NCCIH reports that “significant improvement in sexual function was observed with Tribulus terrestris compared with placebo” after twelve weeks — alongside a 2014 study where it “was not more effective than placebo”. And NCCIH notes “some limited evidence” that ashwagandha “for 2 to 4 months may increase testosterone levels and sperm quality”.
Do those findings apply to this product?
Not at the amounts here. Tribulus terrestris is row eight of nine and ashwagandha is row six, so both are capped at 5 mg. The trials used extracts at research amounts.
Is ashwagandha’s testosterone finding about performance?
No. It is about testosterone levels and sperm quality — fertility markers. NCCIH’s own effectiveness verdict for ashwagandha names insomnia and stress, and neither is sexual.
What is tribulus terrestris?
A spiny ground plant sold for athletic and sexual performance. It has no federal consumer page, but NCCIH cites two trials of it — one positive in 2017, one null in 2014 — inside its digest on this category. It is row eight of nine here.
What is L-arginine doing here?
It is an amino acid, and it carries the nitric-oxide story this category tells. NIH ODS: “some arginine is converted to nitric oxide, a potent vasodilator that can increase blood flow.” ODS discusses it at 2 to 20 grams a day and concludes those doses have “little to no effect on performance”. This row is capped at 5 mg.
Is this product on any FDA list of tainted products?
A search of FDA’s Sexual Enhancement and Energy Product Notifications on September 25, 2026 did not return Maxforce. That is a statement about what a database contained on a date and nothing more. FDA itself notes: “FDA is unable to test and identify all products marketed as dietary supplements that have potentially harmful hidden ingredients.” No test result for this product exists in the public record.
