Analysis

Maca, zinc citrate, magnesium citrate, niacinamide, and calcium provide the recognizable core. Zinc is supplied at a useful 15 mg, while the maca entry gives at least some marker information rather than only a generic powder name.

Two branded complexes are listed without their contents, so their relevance and safety cannot be judged from the supplied data. Flax is only 25 mg, far below an amount that would meaningfully supply fiber, oil, or lignans.

The formula may appeal to someone specifically interested in maca with basic minerals. Limited transparency and the high serving cost undermine the case for choosing it over a simpler, fully disclosed formula.

Who is it for
  • Adults specifically interested in maca-based support
  • People who also want a modest mineral component
Best for
  • Maca plus zinc
  • A compact mineral-and-botanical formula

Pros

  • Useful 15 mg zinc citrate
  • Includes magnesium citrate
  • Maca markers are named
  • Core mineral amounts are disclosed

Cons

  • Two blends hide their ingredients
  • Flax is only 25 mg
  • Calcium and magnesium amounts are modest
  • Weak value for the transparency offered

Nutrient quality

65 Moderate impact

Useful zinc and mineral forms provide a modest nutritional base. Opaque complexes, token flax, and uncertain botanical potency weaken focus.

.

Ingredient transparency

45 Lower impact

Several individual nutrient weights are available. Hidden complexes, ambiguous maca labeling, full directions, and inactive ingredients reduce clarity.

.

Customer satisfaction

63 Moderate impact

The average customer rating is generally favorable. The rating base is adequate but not especially deep, while specific review experiences were not supplied.

.

Value for money

35 Situational impact

Serving economics are weak. Formula weaknesses do not justify the asking price well.

B+ Goal FitA- Strength of SupportB- CoverageB- Formula Quality
Magnesium · 50 mgZinc · 15 mg

Zinc provides relevant support for immunity. Zinc is essential for immune cell development and is a primary ingredient in most effective immune protocols.

An effective organic zinc salt provides sound absorption for routine use. The 15 mg elemental amount is clear and suitable for maintenance, with no high-dose zinc concern.

Magnesium · 50 mgZinc · 15 mg

Zinc and magnesium offer basic nutritional support, but the maca-centered sexual-health formula has limited general-health reach. Evidence is established for zinc as a nutrient, while maca and the proprietary botanical blends have less robust support for foundational wellness.

Zinc at 15 mg is suitable for maintenance, but magnesium and calcium amounts are modest and the botanical active yields are unclear. Zinc citrate and magnesium citrate are useful forms, although two proprietary blends hide their individual ingredients and doses.

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

An effective organic zinc salt provides sound absorption for routine use. The 15 mg elemental amount is clear and suitable for maintenance, with no high-dose zinc concern. Serving value is weak if zinc is the main reason for purchase.

Flax · 25 mg OverallScore16
F Active Ingredient Quality & BioavailabilityF Dose, Safety & Label TransparencyF Value

The small flax inclusion is unlikely to provide a meaningful flaxseed oil, fiber, or lignan dose. Its processing method, sourcing, and oxidation protection are not disclosed, which leaves quality and absorption uncertain. The relatively high serving cost is difficult to justify for such a limited amount.

87 Performance

Zinc Picolinate 25 mg

Thompson
<p>Zinc picolinate offers strong absorption at a meaningful amount below the usual adult upper limit. The lean formula is much easier to judge than the original hidden blends, although it does not include flax or other women’s ingredients.</p>
83 Performance

Zinc 30 mg

Nature's Life
<p>Zinc picolinate with copper provides a more balanced mineral approach than the original zinc-led blend. Repeated copper entries need clarification, and the formula does not retain flax or maca.</p>
85 Performance

OptiZinc

Source Naturals
<p>Zinc methionine and added copper create a well-absorbed, partly balanced mineral formula. It improves transparency and sustained-use practicality compared with the original opaque complexes, while giving up flax and the broader botanical theme.</p>
84 Budget

Zinc Gluconate 30 mg

Swanson
<p>Zinc gluconate provides a substantial, clearly disclosed amount at a tiny fraction of the original serving cost. The focused tablet omits flax, maca, and the hidden botanical complexes, while long-term use without copper may impair mineral balance.</p>
85 Budget

Zinc 30 mg

Nature Made
<p>A focused zinc gluconate tablet offers meaningful zinc support at much lower routine cost. Flax and the women’s botanical ingredients are absent, and prolonged daily use without copper may disturb mineral balance.</p>
85 Budget

Zinc Chelate 30 mg

Nature's Way
<p>Zinc bisglycinate supplies a well-absorbed form in a simple, inexpensive capsule. It improves zinc clarity and cost compared with the opaque original, but it does not replace flax or the broader women’s blend and includes no copper.</p>
86 Value

L-OptiZinc 30 mg

NOW
<p>Zinc monomethionine offers excellent absorption potential and very low routine cost. A small copper addition provides partial balance, though flax and the original women’s botanicals are absent.</p>
87 Value

Zinc Picolinate 22 mg

Solgar
<p>Zinc picolinate supplies a useful maintenance amount in a focused, economical capsule. It improves dose clarity and value over the original, but provides no flax or broader women’s support.</p>
86 Value

Chelated Zinc 30 mg

Carlson
<p>Chelated zinc offers strong absorption and tolerance at favorable serving value. It is clearer and far less costly than the original blend, while long-term use still requires attention to copper intake and no flax is supplied.</p>
