Immune Defense Pack
Metagenics
Overview
This Immune Defense Pack contains several well-researched ingredients known for their immune-supportive properties, many at effective doses. The combination of Vitamin C, Vitamin D, Zinc, Quercetin, and N-Acetyl Cysteine addresses multiple facets of immune health from antioxidant defense to cellular function. However, the exact synergistic benefits of this specific combination and the necessity of all included forms of Vitamin C (e.g., Ultra Potent-C, Calcium Ascorbate, etc.) are not fully elucidated by direct research on this specific product. The inclusion of Alpha D-Ribofuranose derivatives for pain relief, based on preclinical rodent studies, appears out of scope for an immune defense product.
The Good
Optimal doses of key immune nutrients: Vitamin C, D, and Zinc are provided at levels supported by research for immune function.
Comprehensive antioxidant support: Features Vitamin C, Quercetin, N-Acetyl Cysteine (NAC), and Green Tea Extract for broad spectrum antioxidant defense.
Support for respiratory health: NAC's mucolytic properties and its role in glutathione production can benefit respiratory function.
The Bad
Very high Vitamin D dose (5000 IU) requires medical monitoring and is not suitable for all individuals without professional guidance.
Proprietary blend for 'Ultra Potent C' contains several listed ingredients without individual quantities, limiting precise dose assessment.
Niacin content (70mg) may cause a 'niacin flush' in some sensitive individuals.
Is it for you?
Best For: Individuals seeking immune system support, those with Vitamin C or D deficiencies
Skip If: You have pre-existing conditions sensitive to high vitamin dosages or are not able to monitor vitamin D levels.
