Analysis

The formula combines 30 mg of zinc, 5.5 mg of boron, magnesium, selenium, fenugreek, and apple-grape polyphenols. Those ingredients are directionally aligned with male fitness and hormone-support positioning.

Repeated branded totals make the true component breakdown unclear, while a 200 mg proprietary blend hides additional ingredients. The high zinc amount lacks copper, which matters during sustained use.

Two capsules are manageable, but the premium serving cost is hard to justify given the disclosure gaps. Its broad immunity, skin, bone, and vision claims are not well supported by the formula's focus.

Who is it for
  • Adult men considering a targeted hormone-support product
  • Short-term users who verify the current label
  • People focused on zinc, boron, and fenugreek
Best for
  • Testosterone-oriented nutrient support
  • Fenugreek intake
  • Boron and zinc combination

Pros

  • Useful zinc amount
  • Provides boron citrate
  • Includes branded fenugreek

Cons

  • Proprietary blend hides details
  • Repeated branded totals are confusing
  • High serving cost

Warnings

  • Long-term 30 mg zinc use without copper may reduce copper status
  • Fenugreek may lower blood glucose and add to diabetes medication effects
  • The opaque blend prevents complete medication-interaction screening

Nutrient quality

73 High impact

Standardized fenugreek, boron citrate, zinc aspartate, magnesium aspartate, and ViNitrox provide a coherent performance foundation. High zinc and a hidden nutrient blend reduce long-term suitability and dose confidence.

Ingredient transparency

53 Moderate impact

Most named actives have amounts, but the proprietary nutrient blend hides its ingredients and doses. Daily-use directions and inactive capsule ingredients are also missing.

Customer satisfaction

69 High impact

The aggregate rating is favorable and supported by a useful number of reviews. No specific review comments were supplied, so repeated complaints and purpose-related experiences cannot be verified.

Value for money

62 Moderate impact

Meaningful fenugreek and boron doses provide some targeted value. The hidden blend and high zinc reduce confidence relative to fully disclosed competitors.

Zinc, standardized fenugreek, and boron provide a well-aligned combination for foundational steroidogenesis and free-testosterone support. Their amounts are meaningful, while magnesium and vitamin B6 add lighter complementary support.

The formula covers several endocrine pathways with good depth, although proprietary and repeated extract descriptors reduce precision. Regular use of the substantial zinc amount without copper may lower copper status over time.

Zinc, boron, magnesium, and several vitamins provide relevant nutritional support, but the formula is aimed more at male performance than broad daily health. The nutrient base is credible, while the botanical and proprietary components have less certain general-wellness value.

Useful organic mineral forms and meaningful zinc and boron doses strengthen the formula. Long-term daily use of 30 mg zinc without copper may impair copper balance, and the hidden nutrient blend prevents a full dose assessment.

Zinc, vitamin C, and vitamin E support normal repair, collagen-related processes, and antioxidant defense. Their amounts give the formula some real relevance to skin health.

The male-performance botanical blend does not add a clear skin benefit and makes the formula poorly focused. Long-term use of the high zinc amount without copper may disturb copper balance.

Zinc provides the clearest immune contribution, while selenium and vitamin C offer modest support. Most of the formula is aimed at male performance rather than immune function.

The 30 mg zinc amount is relatively high and no copper is included. Long-term daily use alongside other zinc sources may impair copper balance, while proprietary blends prevent full ingredient assessment.

Zinc provides a relevant retinal nutrient, and vitamins C and E add antioxidant support. The product is primarily designed for male performance and lacks lutein, zeaxanthin, copper, and omega-3 fats.

The 30 mg zinc dose is substantial, but no copper is included to support long-term mineral balance. Proprietary performance blends and repeated botanical entries create substantial non-ocular padding.

Zinc provides direct nutritional support for hair when zinc status is low, and the 30 mg amount is substantial. Vitamin C, vitamin E, and selenium add antioxidant support, while the testosterone-focused botanicals have little clear hair value.

Several botanical ingredients sit in proprietary blends, so their individual contributions cannot be assessed. Long-term daily use of 30 mg zinc without copper may lower copper status and can eventually affect blood and nerve health.

Magnesium · 80 mg

Zinc, magnesium, fenugreek, and a grape-apple polyphenol blend provide a plausible mix of mineral, circulation, and recovery support. Zinc is substantial and ViNitrox is clearly identified, but the formula is more focused on male wellness than direct exercise performance.

Magnesium is modest, and a proprietary nutrient blend hides its ingredient amounts. A 30 mg zinc serving without copper also warrants care during prolonged daily use because it may affect mineral balance.

FuranoMax provides a branded, standardized fenugreek extract with clearly identified active markers. The extract amount is useful but falls below the preferred range for concentrated hormonal support, and the dry capsule lacks an absorption enhancer. The serving cost is elevated, though the validated ingredient quality helps support the premium.

The 30 mg zinc serving provides a robust daily amount within the usual upper limit. Zinc aspartate offers a useful absorption profile, while the vegetable capsule shapes convenience and dissolution. No copper is included, so prolonged daily use deserves attention to total zinc and copper intake.

C Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyF Value

The boron citrate dose sits in the preferred range and is clearly listed. The organic citrate form should be reasonably well absorbed, but no trademarked source or purity testing is identified. Its broader men's formula may add value for the intended use, though the boron-specific cost is relatively high.
