Urovance's Measurable Micronutrients: What Vitamin E, B6, Zinc, and Selenium Doses Actually Mean

Why these four numbers, and only these four

Every other named ingredient on the Urovance label — all 17 botanicals, mushrooms and minerals in the Proprietary Blend, plus the disputed Copper line — is either undosed or ambiguous (our companion article on the blend and the Copper strikethrough covers those in full). Vitamin E, Vitamin B6, Zinc and Selenium are different: U.S. labeling rules require vitamins and minerals to be declared individually with an exact amount and a percent Daily Value, and Urovance's label does exactly that for these four. That makes them the only lines on this entire panel where a dose-based evaluation against published research is actually possible. Here is what that evaluation looks like, nutrient by nutrient.

Vitamin E: 6.5 mg (45% DV)

The label lists Vitamin E as D-Alpha Tocopherol Succinate, 6.5 mg, 45% of the Daily Value. The current adult Daily Value for Vitamin E is 15 mg (equivalent to about 22.4 IU of the natural form), so Urovance's 6.5 mg supplies a little under half of that reference intake in a single capsule. The National Institutes of Health's tolerable upper intake level for supplemental Vitamin E in adults is 1,000 mg a day — roughly 150 times what this capsule provides — so 6.5 mg sits well inside the range generally regarded as safe from a toxicity standpoint.

Dose matters here for a reason beyond toxicity, though. The Selenium and Vitamin E Cancer Prevention Trial (SELECT), a large randomized trial in more than 35,000 men, tested 400 IU (about 268 mg) of Vitamin E a day — roughly forty times Urovance's dose — and found a statistically significant increase in prostate cancer diagnoses in the men assigned to Vitamin E after a median follow-up of about seven years^[1]. That finding is specific to a sustained, high daily dose over years, not to any single ingredient's mere presence on a label, and it does not tell you anything about a 6.5 mg dose one way or the other. We mention it because "Vitamin E" as a category has genuine, published, dose-dependent safety research behind it, and a responsible read of any label should note both the finding and the fact that this product's dose is far below the one studied.

Vitamin B6: 1.67 mg (100% DV)

Listed as Pyridoxine Hydrochloride, 1.67 mg supplies exactly 100% of the adult Daily Value for Vitamin B6 — neither a deficiency-range dose nor an aggressive megadose, but the standard reference amount. Vitamin B6 is a cofactor in dozens of enzymatic reactions, including neurotransmitter and hemoglobin synthesis, and a 100% DV dose is a conventional way to include it in a multi-ingredient formula.

B6 is also one of the water-soluble vitamins most associated with a well-documented, dose-dependent risk: peripheral sensory neuropathy from long-term high-dose supplementation. A 2017 toxicology review describes this as "the vitamin B6 paradox" — a nutrient that is essential at normal intakes but can cause nerve damage when taken in excess for extended periods, with case reports typically involving doses in the hundreds of milligrams per day sustained over months or years, not doses near the 1.67 mg found in Urovance^[2]. At 100% DV, this dose is not in the range where that literature raises concern; it is included here so readers who take other B6-containing products can do the arithmetic across everything they use, not just this one capsule.

Zinc: 5 mg (45% DV)

Zinc is listed as Zinc Oxide, 5 mg, 45% of the Daily Value. The adult Recommended Dietary Allowance for zinc is 11 mg for men and 8 mg for women, and the tolerable upper intake level set by the National Institutes of Health is 40 mg a day from all sources combined. At 5 mg, Urovance's dose sits below the RDA on its own and well under the upper limit, so it would need to be combined with meaningful zinc intake from diet or other supplements to approach a level of concern.

Zinc's relevance to this label specifically ties back to the disputed Copper line covered in our companion article. Sustained zinc intake well above the RDA is a recognized, mechanistically understood cause of copper deficiency, because the two minerals compete for the same intestinal transport and metallothionein-binding pathways^[3]. That relationship is precisely why some formulas pair a small copper amount with their zinc line — which makes it notable, not incidental, that Urovance's own copper line is the one row on the panel marked with an unexplained strikethrough.

Selenium: 70 mcg (125% DV)

Selenium is listed as Selenium Gluconate, 70 mcg, 125% of the Daily Value — the highest percentage of any nutrient on the panel. The adult RDA for selenium is 55 mcg, so 70 mcg exceeds the standard recommended intake by a modest margin, while remaining far below the 400 mcg tolerable upper intake level. At this dose, selenium sits comfortably within the range considered safe for regular use.

Selenium and prostate health is an area with a genuinely mixed research record worth knowing about, separate from safety. The same SELECT trial that tested high-dose Vitamin E also tested 200 mcg of selenium a day and found no reduction in prostate cancer risk from selenium alone^[1]. A later systematic review and meta-analysis of the selenium-prostate cancer literature found inconsistent results across studies, with some suggesting a protective association at certain selenium exposure levels and others finding none, concluding that the relationship remains unresolved rather than settled in either direction^[4]. None of that research is about Urovance, and none of it suggests any specific effect, positive or negative, from a 70 mcg dose in this product. It is included so the selenium line on this label can be read against the actual, honestly mixed state of the evidence rather than against a marketing assumption.

Putting the four doses side by side

Nutrient	Urovance dose	% Daily Value	Adult upper intake level
Vitamin E	6.5 mg	45%	1,000 mg/day (supplemental)
Vitamin B6	1.67 mg	100%	100 mg/day
Zinc	5 mg	45%	40 mg/day
Selenium	70 mcg	125%	400 mcg/day

Upper intake levels are drawn from National Institutes of Health Office of Dietary Supplements reference data and apply to total daily intake from all sources, not from this product alone. Every one of Urovance's four dosed nutrients sits at a small fraction of its respective upper limit on its own; the figures above are for context, not a suggestion that these levels are close to being reached by this product by itself.

The contrast this piece is really making

These four nutrients are the only part of the Urovance panel where "what does this dose mean" is even an answerable question, because they are the only lines with a printed amount. The 400 mg Proprietary Blend sitting below them on the same label contains 17 additional names — including Saw Palmetto, Pygeum Africanum and a Plant Sterol Complex, ingredients with genuine published research behind them in other contexts^[5][6] — but with no individual amount disclosed for any of them, that research cannot be matched against a specific dose the way it can for Vitamin E, B6, Zinc and Selenium. That asymmetry, not any claim about effectiveness, is the point of separating this label into its dosed and undosed halves.
