An affordable, broad-spectrum antioxidant and mineral supplement from 21st Century, offering basic support for general health and immunity. It contains essential vitamins (A, C, E) and minerals (Zinc, Selenium, Copper, Manganese, Calcium) but uses less bioavailable forms and lower dosages for some ingredients compared to premium alternatives.
21st Century Antioxidant is formulated as a general health supplement with a focus on antioxidant support, containing Vitamins A, C, E, and key minerals like Zinc, Selenium, Copper, Manganese, and Calcium. The product is highly affordable, making it accessible to a wide consumer base. While it covers several essential micronutrients known for their roles in immunity, skin health, and anti-aging, the choice of ingredient forms (e.g., zinc oxide, cupric oxide, DL-alpha-tocopheryl acetate) is often associated with lower bioavailability compared to chelated or natural forms, which could reduce the actual benefit derived. Furthermore, the dosage of selenium at 15mcg is significantly below the recommended daily intake for adults (55mcg), and the 100mg of calcium is negligible for bone health support on its own. The product aims to address a wide range of health goals, but this broad approach, combined with the aforementioned ingredient choices and dosages, suggests it functions more as a general nutritional top-up rather than a highly potent or targeted solution for complex health concerns.
- Very affordable price point per serving.
- Contains a broad spectrum of common antioxidant vitamins (A, C, E) and essential trace minerals.
- Good for general daily nutritional support and filling minor dietary gaps.
- Uses less bioavailable forms for some key minerals like Zinc (Zinc Oxide) and Copper (Cupric Oxide), which may reduce absorption.
- Includes synthetic Vitamin E (DL-Alpha-Tocopheryl Acetate) which is less potent than natural D-alpha-tocopherol.
- Dosage of Selenium (15mcg) is notably low for optimal benefits.
- Calcium content (100mg) is minimal and insufficient for significant bone health support.
- Individuals with specific deficiencies or health conditions might require higher doses or more bioavailable forms of certain nutrients not adequately provided by this supplement.
- Those taking other supplements or medications should consult a healthcare professional to avoid potential interactions or excessive nutrient intake, especially with fat-soluble vitamins (A, E) and minerals like Copper and Zinc, which can interact.

Categories
Vitamin C 70.0
Contains 250mg of Ascorbic Acid, which is a standard and effective form of Vitamin C. This dosage provides a good daily intake for antioxidant support and general immune function, although higher doses are often preferred for specific therapeutic effects.
Manganese 70.0
Provides 1.50mg of Manganese as Manganese Sulfate, which is a common and generally bioavailable form for this mineral. This dosage is appropriate for contributing to bone health and metabolic functions without exceeding typical dietary intake.
Copper 60.0
Contains 1.00mg of Copper as Cupric Oxide. While the dosage meets daily requirements, Cupric Oxide is known to have lower bioavailability compared to other forms like copper gluconate or chelated copper, potentially limiting its absorption and effectiveness.
Goals
General Health 75.0
As a general health supplement, it provides a foundational blend of essential vitamins and minerals that contribute to various bodily functions. Its affordability makes it a good option for basic nutritional coverage, despite some ingredients being in less optimal forms or lower dosages for specific high-impact benefits.
Immunity 70.0
The product contains Vitamin C (250mg), Zinc (7.5mg), Selenium (15mcg), and Vitamin A (1500mcg), all of which play roles in immune function. While Vitamin C and A dosages are reasonable, the Zinc is in a less bioavailable form (oxide) and Selenium is at a very low dose, limiting its overall strength for robust immune support compared to more focused immune supplements.
Skin Health 65.0
Vitamins A, C, and E are well-known for their skin health benefits, and Zinc and Copper also contribute to collagen formation and wound healing. However, the synthetic form of Vitamin E and less bioavailable forms of Zinc and Copper, combined with potentially sub-optimal dosages for comprehensive skin benefits, mean its impact might be moderate.
