About this product

The formula is most relevant to normal immune function and skin nutrition when dietary intake is inadequate. Vitamin C supports collagen formation, and zinc and selenium supply nutrients used by the immune system. Taking extra amounts once nutritional needs are met does not establish added benefit.

Zinc citrate and L-selenomethionine provide favorable mineral forms, with 15 mg zinc suited to a maintenance role. The 500 mg vitamin C is supplied as buffered calcium ascorbate, but that form does not establish better skin or immune outcomes. The separate calcium declarations leave the source proportions unclear, so a combined calcium amount should not be assumed.

Expectations for hair growth, stronger nails, improved vision or higher testosterone should stay modest because the relevant findings depend on nutritional status or specific circumstances. The 268 mg vitamin E serving does not establish extra benefit for these goals. The serving cost gives limited value for vitamin C, zinc and selenium, making the combination harder to justify when only one nutrient is needed.

Who is it for
  • Adults who need several of the included nutrients rather than a single supplement
  • People seeking maintenance-level zinc with vitamin C and selenium
Best for
  • Filling selected nutrient gaps related to normal immunity
  • Supporting normal skin nutrition when intake is inadequate

Pros

  • The zinc source and elemental amount are clearly stated
  • Zinc citrate is favorable for absorption
  • Selenium uses L-selenomethionine
  • Vitamin C is supplied in a buffered mineral form

Cons

  • The serving cost offers limited value across the main nutrient contributions
  • Broad beauty and hormone uses are not established for adequately nourished adults
  • The proportions of the calcium sources are unclear

Warnings

  • Include the 100 mcg selenium serving in your total from other supplements; excessive selenium intake can affect hair and nails.

Product analysis

60 out of 100

ACES+Zn supplies nutrients that support normal immune function and collagen formation, with benefits most relevant when intake is low. Several of its key nutrients are relatively expensive for the content supplied.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality54

Zinc citrate and L-selenomethionine are favorable, clearly identified forms. Quality across the complete mixture remains uncertain because several other forms are unspecified or cannot be compared confidently.

Ingredient Transparency68

All listed amounts and most forms are disclosed, helping compare the main nutrients. Some forms and the proportions of calcium sources remain unclear.

Value For Money29

Vitamin C, zinc and selenium are relatively expensive for their content. Other comparisons remain uncertain, giving the complete formula limited demonstrated value.

Customer Satisfaction93

Customer feedback is very positive across thousands of ratings. The large review pool gives a substantial view of satisfaction without proving health effects.

Product Focus69

The formula supports several nutritional functions, with the clearest benefits when intake is low. Its wide range of suggested uses does not establish equally reliable benefits for every purpose.

Vitamin A supports normal barriers, while zinc and selenium supply nutrients relevant to normal immune-cell function. Vitamin C adds modest regular-use cold-duration support rather than infection prevention. Vitamin E receives a contribution in the saved findings, but mixed respiratory-outcome evidence does not establish extra protection in well-nourished adults.

Vitamin C has antioxidant functions; a large trial was null overall, with CRP improvement confined to people starting with elevated CRP.

Vitamin C supports normal collagen formation and can restore impaired wound healing caused by low intake. Its presence does not establish added cosmetic benefit when intake is adequate. Vitamin E and selenium have antioxidant roles, but those roles do not establish routine oral skin improvement. The C/E combination does not match the supplied high-dose UV studies or establish sunscreen-like protection. Zinc also supports repair when intake is low.

How this ingredient is rated

Active Ingredient Quality & Bioavailability80

Citrate is a favorable zinc form for absorption, and the source is clearly identified.
Zinc Form Bioavailability
Zinc citrate is the sole identified source, with a favorable absorption profile.

Dose, Safety & Label Transparency61

The amount of zinc itself is clearly disclosed. Copper content is unknown, so the balance between these minerals remains unverified.
Elemental Dose Transparency
The label clearly states 15 mg of zinc and identifies its source as zinc citrate.
Zinc Dosage Safety & Effectiveness
The serving supplies a clearly stated 15 mg of zinc, a moderate zinc contribution.
Zinc-to-Copper Mineral Balance
Copper content is unknown, so the zinc-to-copper balance cannot be assessed; unknown does not mean copper is absent.

Value30

The whole-product serving costs about $0.56; this is the price of the complete serving, not a price for zinc alone.
Price Per Serving Efficiency
About $0.56 buys one whole-product serving, rather than an isolated quantity of zinc.

81 Performance

L-Lysine 985 mg

Solaray

L-lysine, 1000 mg of vitamin C, and zinc shift the formula toward tissue repair, skin, and immune support rather than a broad antioxidant blend. Repeated zinc entries make the total form and amount ambiguous, and selenium is absent.

77 Performance

Immune Intensive

Seeking Health

Buffered vitamin C, zinc citrate, vitamin D3, and vitamin K2 broaden immune and bone support while avoiding the original's high vitamin E amount. Vitamin D exceeds the adult daily upper limit, and preformed vitamin A requires attention to total intake.

76 Performance

Immune Booster

NaturesPlus Source of Life

Vitamin C, zinc, natural vitamin E, and standardized andrographis, echinacea, and elderberry provide broader botanical immune support with much less vitamin E than the original. The formula omits selenium, and its botanical amounts are moderate.

Immufight Daily defense

Solaray

Buffered vitamin C, vitamin D3, zinc citrate, and selenomethionine provide broad immune coverage at better serving value. The formula avoids the original's high vitamin E and beta-carotene, though modest accessory ingredients and grapefruit seed extract reduce its appeal.

77 Budget

Vitamin C + D3 & Zinc

NutriBiotic Immunity

A simple vitamin C, vitamin D3, and zinc combination costs less per serving while covering core immune nutrients. Vitamin D exceeds the adult daily upper limit and zinc reaches that limit, so the low cost comes with an aggressive routine-use profile.

Healthy Eyes Lutein and Antioxidants

21st Century

Lutein with lower beta-carotene and vitamin E amounts creates a less costly, more eye-focused alternative to the original antioxidant blend. Zinc reaches the adult daily upper limit and several mineral forms are weak, so long-term use still needs care.

Vitamin C 1000 mg with Zinc 45 mg

Vitamin C, vitamin E, selenium, and lutein provide eye-oriented antioxidant coverage at strong serving value. Vitamin E and beta-carotene are more moderate than in the original, but zinc reaches the adult daily upper limit and several mineral forms are weak.

74 Value

Immufight Maximum Daily Defense

Solaray

Buffered vitamin C, zinc citrate, selenomethionine, and monolaurin broaden immune support without the original's high vitamin E and beta-carotene. Duplicate vitamin D entries need clarification, and grapefruit seed extract may interact with medicines.
