Analysis

DEVA Quercetin Zinc+ is an immune support supplement featuring a blend of well-regarded forms of zinc (amino acid chelate and citrate), totaling a high 50mg of elemental zinc. This substantial zinc dose is complemented by significant amounts of Quercetin, Elderberry fruit extract, Echinacea, and Oregano leaf extract, all commonly used for their immune-supporting properties.

However, the copper content is extremely low at just 0.23mg from copper amino acid chelate. This creates a highly imbalanced zinc-to-copper ratio (approximately 217:1), which could potentially lead to copper deficiency if this product is used regularly over an extended period without additional copper intake. While the botanical blend is impressive for immune support, the mineral balance needs consideration.

This supplement is best suited for individuals seeking comprehensive immune support with a high dose of zinc, who are also conscious of their copper intake from other sources or for shorter, targeted immune-boosting cycles. Its strength lies in its diverse immune-supporting botanicals, but the mineral ratio is a notable drawback for long-term general use.

Pros

  • Contains two well-absorbed zinc forms (amino acid chelate, citrate).
  • Includes powerful immune-supporting botanicals (Quercetin, Elderberry, Echinacea, Oregano).
  • High 50mg zinc dose may be beneficial for specific, acute needs.
  • A vegan-friendly formulation, appealing to a specific demographic.

Cons

  • Extremely low copper content (0.23mg) relative to zinc.
  • Highly imbalanced zinc:copper ratio (approx. 217:1).
  • Not suitable for long-term daily use without separate copper supplementation.
  • Higher zinc dose than typically recommended for daily maintenance.

Warnings

  • The very high zinc dose (50mg) should be used cautiously and is generally not recommended for prolonged daily use without professional guidance.
  • The extreme zinc to copper imbalance can lead to copper deficiency and related health issues if used long-term without additional copper intake.
  • Consult a healthcare professional before use, especially if you are taking other supplements, medications, or have existing health conditions due to the high zinc and botanical blend.

Zinc provides foundational support for skin tissue repair and the maintenance of a healthy inflammatory response. Quercetin serves as an antioxidant that may help protect the dermal layers from environmental damage and irritation.

While the zinc dose is high, the copper concentration is too low to maintain mineral balance over the long term. This formula offers focused mineral and antioxidant support but lacks comprehensive building blocks for skin structure.
