That never changes what we publish — and here it means answering the DIM3X questions head-on, including the awkward ones: why only one of its four ingredient amounts is printed, why its guarantee paragraph names a different product, and why a hormone-positioned formula carries no warnings section at all. DIM3X earns an Our Score of 6.5/10 in our review. This page shows what that score is made of.
Quick Answer: What Is DIM3X?
What it is: a DIM (diindolylmethane) capsule from PrimeGENIX, a Leading Edge Health brand, positioned for men aged 40 and over who want to support hormone balance — the maker frames it as reducing "harmful estrogen" and supporting healthy testosterone production. The dose: one capsule a day with meals, delivering a disclosed 200 mg of DIM . Does it work? The evidence the maker publishes is ingredient-level only: it calls the 200 mg dose "clinically dosed" and used in human studies, but names no study, and no trial of the finished product is described. Price and guarantee: $59 for one bottle, with pack and subscription prices published, under a 67-day money-back guarantee.
What Is Actually in It?
Four named ingredients — and only one published amount. DIM — 200 mg per capsule , stated plainly by the maker ("clinically dosed with 200 mg of high-quality DIM"), and the only figure a buyer can check. Vitamin E — quantified only as 134% of the daily value per dose; the milligram amount is not published. AstraGin® (Panax notoginseng and Astragalus membranaceus), a patented absorption ingredient — amount not published. BioPerine® , a patented black pepper extract, also for absorption — amount not published. No proprietary blend is claimed, which makes the gaps more conspicuous, not less: the formula is four items long, and three of them cannot be dose-checked. The full Supplement Facts panel and the excipient list also do not appear in the product page text. The maker's stated badges: U.S. patented ingredients, cGMP-certified manufacturing, an FDA-registered and inspected facility, no prescription required, and zero gluten, soy, eggs or dairy.
Has DIM3X Been Tested?
Not as a finished product — at least, no trial of DIM3X itself is described anywhere on the maker's page. What the maker offers instead is a set of ingredient-level assertions. The 200 mg DIM dosage "has been used successfully in human clinical studies" — no study named, cited or linked, so no design, participants or sponsor can be checked. AstraGin® is "clinically proven to improve nutritional absorption… backed by 24 studies" — the studies are not named. "Clinical studies show BioPerine® can help absorption by 30% to 60%" — again unnamed. The maker also states its products are third-party lab tested, with Certificates of Analysis, and describes itself as consulting medical professionals; the formula is presented on the page by a named presenter, Dr. Redden, in an on-page science section. Read the file as it stands: an established maker's quality policies, wrapped around an evidence core that a reader cannot inspect. Our evidence sub-score is 5.5/10, and this paragraph is why.

How Long Does the Maker Say It Takes?
The maker says you "could begin noticing the hormone-balancing benefits, starting in just 2 weeks," and its FAQ repeats that results could start in two weeks — while adding that "the longer you take DIM 3X the more you could benefit" and that balancing hormones "is not a simple 'overnight' trick." Hold both halves together: a two-week first-signals claim attached to an open-ended course. The practical use of those numbers is in the guarantee maths below — the 67-day window covers the maker's own two-week checkpoint several times over, so a buyer can test the maker's first promise well inside the refund period, which is more than many products in this family allow.
Is It Safe? The Missing Warnings Section
Here is the honest gap, and it is the largest one on this page. The maker publishes no safety section, no warning list and no exclusion list for DIM3X. Its entire safety content is the FAQ answer — "DIM 3X is an all-natural formula with no reported negative side-effects" — repeated in the body copy and as a "No Negative Side-Effects" badge. Nothing on the page addresses prescription medication, hormone-sensitive conditions, pregnancy, anyone under 18, or use alongside testosterone replacement therapy. That silence matters precisely because of the product's positioning: this is a formula sold to men around estrogen and testosterone, a readership heavily represented by men on prescribed hormone management. An absolute "no reported side effects" line is a claim, not a safety file — and the absence of published guidance is not evidence that no caution is needed. If you take prescription medication, have a hormone-related condition, or are on TRT, the maker's page gives you nothing to rely on; the question belongs with a qualified clinician before you buy. Our safety sub-score: 6.5/10 — credit for stated cGMP manufacture and third-party testing, docked for the missing warnings.
What Does It Cost — and What Does the Guarantee Really Say?
One bottle is $59 . Three bottles cost $165 ($55 per bottle); six cost $294 ($49 per bottle); a monthly subscription runs $49 per bottle, with free shipping in the USA and Canada as the maker states it, and the maker also shows the product as HSA/FSA eligible. Two reading traps on the maker's own page deserve naming. First, the page header summarises "Buy Once from $49" — but $49 is the six-bottle per-bottle price (and the subscription price); a single bottle bought once is $59. Second, the number of capsules in a bottle is not published on the product page, even though the dose is one capsule a day — so the page does not state how many days one bottle covers. The guarantee is 67 days : the maker's FAQ describes returning the empty bottles within 67 days for a refund of the purchase price minus shipping, while its guarantee block describes returning "the unused portion in the original container" within 67 days of receiving the order, on the same refund-minus-shipping basis. The period and refund basis agree; the container wording does not. And one paperwork oddity a buyer is entitled to know: the guarantee section on the DIM3X page names a different product — it reads "That's why Testodren™ comes with a 100% satisfaction, 67-day, money-back guarantee… Give Testodren™ a risk-free try today" — and an energy section on the same page ends by urging the reader to try "Nitric Pump – Fruit Punch Flavor." Those are copy errors carried over from other products' pages. They do not change DIM3X's facts, but they are careless work on the page a buyer is asked to trust, and our maker-credibility score (7.0/10) reflects them.
Frequently Asked Questions
How much DIM is in DIM3X?
200 mg per capsule, per the maker — the only ingredient amount published. The daily dose is one capsule, taken with meals.
Are all the ingredient amounts published?
No. Vitamin E is stated only as 134% of the daily value, and the AstraGin® and BioPerine® amounts are not published. The excipients and a full Supplement Facts panel are also not published in the page text.
Has DIM3X been clinically tested?
No trial of the finished product is described on the maker's page. The maker says the 200 mg DIM dose has been used in human clinical studies and makes study claims for AstraGin® and BioPerine®, but names none of those studies.
Can I take DIM3X with medication or on TRT?
The maker publishes nothing on medication, hormone-sensitive conditions or TRT. Do not treat that silence as reassurance — ask a qualified clinician first, and never adjust a prescribed therapy around a supplement.
How many capsules are in a bottle?
The maker does not publish the capsule count on the product page, even though it states the one-capsule daily dose.
What is the guarantee, exactly?
67 days, for a refund of the purchase price minus shipping. The FAQ describes returning the empty bottles; the guarantee block describes returning the unused portion in the original container. The two wordings differ on the container, not on the period or the refund basis.
Our Verdict: 6.5/10, and Why
Our Score: 6.5/10 — Ingredients 7.0 · Evidence 5.5 · Maker credibility 7.0 · Safety 6.5 · Value 6.0. DIM3X gets the basics of auditability half right: a short formula, a plainly printed headline dose of 200 mg of DIM, published pack pricing, and a written 67-day guarantee that covers its own two-week first-signals window. The other half is missing: three unpublished amounts, no named study behind its "clinically dosed" language, no trial of the product itself, no warnings on a hormone-positioned formula, and a sales page carrying two other products' copy. Buy it, if you buy it, as a disclosed-DIM formula with an incomplete file — and if hormones are a medical matter for you rather than a shopping category, start with our Testodren review for the same maker's paperwork standard, and with your clinician for everything else.
