Analysis

Zinc citrate and boron provide the strongest nutritional foundation, while branded tongkat ali adds a more targeted botanical pathway. Tribulus, shilajit, arginine, and saw palmetto broaden the formula across libido, circulation, and androgen-related mechanisms.

Arginine is well below common standalone amounts, and tribulus lacks a disclosed saponin standard. Shilajit has no purity or contaminant-testing information in the supplied data, while saw palmetto is modest and not standardized.

Boron is listed in three forms at the same amount, which may describe one blended total or three additive doses. The package label must clarify the actual total because an additive interpretation would exceed the usual adult upper intake level.

Who is it for
  • Adult men seeking targeted testosterone and libido support
  • Users who have verified the total boron amount
  • People comfortable with a multi-botanical formula
Best for
  • Testosterone-related nutrient support
  • Libido-focused supplementation
  • Zinc and tongkat ali in one formula

Pros

  • Zinc citrate form
  • Branded tongkat ali extract
  • Clearly named botanical actives
  • Multi-pathway men’s-health design

Cons

  • Boron total is ambiguous
  • Arginine amount is modest
  • Tribulus is not standardized
  • No shilajit purity-testing disclosure

Warnings

  • Verify the total boron on the package; if all three listed amounts are additive, intake would exceed the usual adult upper limit.
  • Arginine may further lower blood pressure when combined with nitrates, antihypertensive medicines, or other vasodilators.
  • Saw palmetto may increase bleeding risk with anticoagulant or antiplatelet medicines.
  • The supplied data do not confirm purified or contaminant-tested shilajit, an important quality consideration for this ingredient.

Nutrient quality

74 High impact

Strong zinc and boron forms plus branded tongkat ali create a relevant core for the intended use. Several secondary ingredients lack standardization or meaningful dose depth, while zinc and boron are aggressive for routine use.

.

Ingredient transparency

79 High impact

Every active amount is disclosed without a proprietary blend, and the main forms are understandable. Missing directions, absent excipients, and incomplete extract standardization limit full transparency.

.

Customer satisfaction

61 Moderate impact

The favorable aggregate rating has only a modest review base. No specific feedback is supplied to assess tolerance, recurring complaints, or whether experiences match testosterone and libido use.

.

Value for money

48 Lower impact

The core minerals and branded tongkat ali provide real value, but several secondary actives are too modest to justify the broad label. A relatively costly serving and short supply weaken category competitiveness.

Zinc, boron, and branded tongkat ali create strong multi-pathway alignment for testosterone support. Tribulus and shilajit add breadth, although their disclosed amounts and evidence are less convincing than the core minerals.

The label clearly names the main doses and uses solid zinc and boron forms. The formula is well targeted, but several secondary ingredients appear too modest or weakly supported to carry equal weight.

Zinc citrate provides a meaningful immune-active amount in a bioavailable form. The rest of the formula is directed toward libido and male hormonal support rather than immunity.

Botanicals and amino acids do not broaden the key immune pathways assessed here. It functions as a zinc-containing specialty formula, not a comprehensive immune product.

Zinc and boron provide legitimate mineral support, but the formula is designed mainly for libido and hormone-related use. Several botanicals have less direct relevance to broad daily health than core vitamins, minerals, or essential fats.

The zinc and boron forms are clearly named and supplied at substantial amounts. Arginine and the botanical extracts are also disclosed, although the high boron level makes this a targeted formula rather than a routine all-purpose supplement.

Zinc · 20 mg

Zinc at 20 mg can support follicle cell division when zinc status is low, and saw palmetto offers a plausible hormonal pathway. The saw palmetto amount is small and lacks extract standardization, limiting confidence in its hair contribution.

The formula was built for testosterone and libido rather than hair, so several botanicals do not serve the selected goal. Zinc is clearly disclosed, but the overall ingredient balance is not optimized for sustained hair support.

Boron and zinc contribute trace-mineral support that may matter for bone metabolism. The formula is primarily designed for testosterone and libido rather than skeletal health.

Both minerals are supplied at substantial disclosed amounts and use defined organic forms. The lack of calcium, magnesium, vitamin D, vitamin K, and matrix support leaves the bone-health profile narrow.

Report overview
Zinc (Zinc Citrate) · 20 mg OverallScore75
B+ Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyF Value

The zinc citrate source offers sound form quality, while the vegetable capsule format is well suited to use. Its 20 mg elemental serving is clearly stated and fits a maintenance range. Copper omission poses little concern at this amount, while value is weak because it costs well above the collection benchmark.

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

Boron aspartate, citrate, and glycinate create a clearly defined three-form complex with useful absorption potential. The disclosed 10 mg serving reaches the higher supplemental range while staying below the adult upper limit. Normalized value is weak because the broader formula is costly as a boron source.

D+ Active Ingredient Quality & BioavailabilityB- Dose, Safety & Label TransparencyF Value

Fruit extract is a favorable source, but no saponin percentage is provided. The Tribulus amount reaches the collection median and is clearly stated. Value is poor because the serving is costly for a modest, incompletely standardized dose.
