Analysis

Vitamin C at 1,000 mg, vitamin D3 at 62 mcg, zinc citrate at 20 mg, and elderberry at 375 mg give the formula a clear immune focus. Echinacea, standardized andrographis, astragalus, garlic, reishi, and quercetin extend the botanical coverage.

Several ingredient choices are less convincing. Sodium selenite is a basic selenium form, astragalus and reishi lack standardization details, and the small copper amount does not create an ideal balance with 20 mg zinc.

Three capsules per serving and a generous supply make ongoing use convenient, but the formula is not broadly suitable. Bovine colostrum and transfer-factor ingredients exclude vegans and may be unsuitable for people with milk allergy, while high-dose vitamin C can affect tolerance.

Who is it for
  • Adults seeking a broad daily immune formula
  • People wanting elderberry with echinacea and andrographis
  • Non-vegan users without milk allergy
Best for
  • Multi-ingredient immune support
  • Combining core nutrients with botanical extracts
  • Longer routines with a moderate capsule count

Pros

  • Provides meaningful vitamin C, vitamin D3, and zinc amounts
  • Includes 375 mg elderberry extract
  • Uses standardized andrographis
  • Offers a practical number of servings

Cons

  • Uses sodium selenite rather than a preferred organic selenium form
  • Copper amount is low relative to zinc
  • Several botanicals lack active-yield details
  • Contains animal-derived colostrum

Warnings

  • Bovine colostrum may be unsuitable for people with milk allergy and is not vegan
  • Vitamin C at 1,000 mg may cause diarrhea or stomach upset
  • Zinc at 20 mg may contribute to mineral imbalance when stacked with other zinc products
  • Garlic and andrographis may require extra caution with anticoagulant or antiplatelet medicines

Nutrient quality

75 High impact

Vitamin C, vitamin D3, zinc citrate, elderberry, echinacea, and andrographis provide a meaningful immune core. Sodium selenite and several small or incompletely standardized additions reduce form quality and focus.

Ingredient transparency

81 Highest impact

Every listed active has a separate amount and no proprietary blend hides the formula. Several extracts omit ratios or active markers, while usage directions and the complete inactive-ingredient list are not supplied.

Customer satisfaction

68 High impact

The favorable average rating has a modest review base and supports cautious confidence. No review excerpts describe tolerance, capsule use, or recurring complaints, so firsthand experience remains unclear.

Value for money

77 High impact

Meaningful core nutrient and botanical doses come in a long supply with favorable serving value. Less refined selenium and several small secondary additions prevent the formula from matching the quality of the strongest premium competitors.

Vitamin C, vitamin D3, zinc, vitamin A, elderberry, echinacea, and andrographis create strong direct immune coverage. The principal nutrients and elderberry reach meaningful amounts rather than appearing only as label decoration.

Several botanical extracts lack ratios or active-marker standardization, and sodium selenite is a less favorable selenium form. Mushroom, colostrum, and transfer-factor additions are small and make the otherwise focused formula more crowded.

Vitamin C, vitamin D, zinc, and selenium provide a strong foundational core within the immune-focused blend. The nutrients have established roles, while the botanical, mushroom, colostrum, and transfer-factor evidence is less consistent.

The main vitamins and zinc are meaningfully dosed, while several later immune ingredients are modest. Most amounts are clear, but sodium selenite and incompletely standardized extracts limit form quality.

Vitamin C, vitamin D3, zinc, andrographis, elderberry, echinacea, garlic, and mushrooms cover antioxidant and immune-inflammatory pathways. Vitamin C, vitamin D, zinc, and several botanicals are present at useful amounts.

Selenium uses less-retained sodium selenite, and some extracts lack active-marker standardization. The broad immune formula remains more coherent than a kitchen-sink blend but still contains several secondary additions.

Vitamin D3 and zinc reach useful amounts for supporting natural endocrine function when either nutrient is low. Selenium adds general reproductive and antioxidant nutrition without acting as a primary testosterone ingredient.

The key amounts are clearly disclosed, though sodium selenite is a less preferred selenium form. The immune-focused formula offers solid foundational coverage but no stress modulator or meaningful free-hormone support.

Selenium, Zinc, and Vitamin C offer only a limited connection to focused skin health. Some relevant amounts are useful, while others are better suited to basic nutrition.

Coverage reaches collagen synthesis and oxidative defense. The broader formula is designed for another purpose, so several ingredients add little skin-specific value.

Vitamin C, D3, zinc citrate, selenium, and quercetin give the formula useful antioxidant and nutritional coverage. The mixture also touches inflammatory and cardiovascular resilience through garlic and several extracts.

Its main purpose remains immune support, and several mushrooms, colostrum, and transfer-factor additions are too small or poorly standardized to judge confidently. Inorganic selenium is another form-quality limitation.

Vitamin C, vitamin D3, and zinc provide useful follicle and collagen support. The mushroom, colostrum, and immune botanicals are not targeted to hair growth.

Core nutrient amounts are meaningful, but selenium uses a less retained form and copper is very low. The immune-oriented blend offers some nutritional overlap without structural proteins or hormonal support.

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

Elderberry fruit extract is clearly identified, but no concentration ratio or active-marker standardization is provided. The disclosed amount reaches a strong practical dose. Low cost per active weight gives it excellent elderberry-specific value.

Zinc (Zinc Citrate) · 20 mg OverallScore77
B+ Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyD+ Value

The zinc citrate source offers sound form quality, while the standard capsule format is serviceable. Its 20 mg elemental serving is clearly stated and fits a maintenance range. Copper omission poses little concern at this amount, while value is mixed because it falls into an unlisted middle price band.

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

The three-capsule serving delivers 1,000 mg of generic ascorbic acid alongside vitamins, minerals, mushrooms, and botanicals. Its vitamin C dose is well targeted and clearly separated, but no enhanced delivery or buffering is identified. Cost efficiency for vitamin C is marginal because much of the serving value lies in the wider formula.
