QUERCETIN, ZINC, VITAMIN C, VITAMIN D & ELDERBERRY
Clean Nutraceuticals
Overview
This supplement aims to boost the immune system through a combination of vitamins, minerals, and herbal extracts. While some ingredients are included at clinically relevant levels, the proprietary blend raises concerns regarding the dosage and potential efficacy of its individual components. The excessively high doses of Vitamin C and Zinc may also be problematic for some users.
The Good
Includes Vitamin C at a high dose, known for its role in immune support and antioxidant properties.
Vitamin D3 at a substantial dose (125mcg, 625% DV), supports immune function and bone health.
Contains Zinc in multiple bioavailable forms (citrate, gluconate, picolinate), essential for immune function and various enzymatic processes.
The Bad
High Vitamin C Dosage: Contains a very high dose of Vitamin C (1000mg, 1111% DV), which may cause gastrointestinal distress in sensitive individuals.
Potential Zinc Overdose: The 50mg zinc dose exceeds the tolerable upper intake level (UL) of 40mg per day, potentially leading to copper deficiency or other adverse effects with long-term use.
Proprietary Blend Concerns: The 'Clean Q-Defend Proprietary Blend' makes it impossible to determine the exact dosage and effectiveness of individual ingredients.
