Analysis

This multi-nutrient tablet includes Vitamin A, C, and E along with trace minerals like zinc, selenium, and 1 mg of copper. It is formulated as a general-purpose antioxidant support tool for daily use. The price is very low, making it accessible for those on a strict budget who want broad coverage.

A significant drawback is the use of cupric oxide, which is a form of copper known for very low bioavailability. This means the 1 mg provided may not be fully utilized by the body compared to chelated versions. It is a better fit as a general vitamin backup rather than a targeted mineral supplement.

Pros

  • Includes vitamins A, C, and E
  • Very inexpensive
  • Broad antioxidant support
  • Once-daily tablet
  • Good for basic vitamin gaps

Cons

  • Uses copper oxide (low absorption)
  • Low selenium content
  • Mineral forms are generally poor quality

Warnings

  • May not be effective for correcting a copper deficiency
  • Take with food to improve vitamin absorption
  • Not a substitute for a high-quality mineral chelate

Nutrient quality

66 High impact

Bioavailability is compromised by the use of less-absorbed inorganic mineral forms like cupric oxide. While it offers broad coverage, the low selenium dose may not provide robust support.

Ingredient transparency

98 Highest impact

Labeling identifies all active components and their chemical forms, which supports informed choice. The clear disclosure of each dosage avoids the confusion of proprietary mixtures.

Customer satisfaction

93 Highest impact

A 4.70 rating from over 1,700 users indicates a generally positive response to the product's quality. User feedback reflects satisfaction with its broad approach to nutritional support.

Value for money

85 Highest impact

High affordability is a key strength, although it comes at the cost of mineral bioavailability. This option is a budget-friendly choice for those needing broad but low-potency support.
