Metagenics Ultra Potent-C 1000 is a high-dose, buffered Vitamin C supplement with bioflavonoids, offering excellent immune and antioxidant support. Its glutathione content is negligible, so it's best for focused Vitamin C benefits.

Analysis

Ultra Potent-C 1000 focuses on delivering a potent dose of Vitamin C (1000mg) in a buffered form, which can be gentler on the stomach for some individuals. The inclusion of Citrus Bioflavonoid Complex (32mg) is beneficial as bioflavonoids are known to enhance the absorption and utilization of Vitamin C. While it lists 5mg of L-Glutathione and 8mg of L-Cysteine, these dosages are far too low to provide meaningful detoxification or anti-aging benefits typically associated with these compounds. The product excels as a targeted Vitamin C supplement for immunity, anti-inflammatory support, and skin health due to its high C content and synergistic bioflavonoids. Metagenics is a brand often recommended by practitioners for its quality and research focus.

Pros
  • Provides a high and effective 1000mg dose of buffered Vitamin C for optimal absorption and reduced gastric upset.
  • Includes Citrus Bioflavonoid Complex to enhance Vitamin C's efficacy.
  • From Metagenics, a brand trusted by healthcare practitioners for quality.
  • Strong support for immunity and skin health through its primary ingredient.
Cons
  • L-Glutathione (5mg) and L-Cysteine (8mg) dosages are too low to provide significant benefits for detoxification or anti-aging.
  • Price per serving is higher than many basic Vitamin C supplements, though justified by buffering and bioflavonoids.
  • Not a multi-nutrient supplement for broad health goals beyond Vitamin C's scope.
Warnings
  • Individuals sensitive to Vitamin C, even buffered forms, should start with a lower dose.
  • Consult a healthcare professional if on medication, as high doses of Vitamin C can interact with some drugs.

Report overview

Categories

Despite being in the 'Glutathione' collection, this product contains only 5mg of L-Glutathione, a dose that is far too low to provide any meaningful benefits associated with glutathione supplementation. It is primarily a Vitamin C product, not a glutathione supplement.

Goals

With a robust 1000mg of Vitamin C, a crucial immune booster, supported by bioflavonoids, this product is highly effective for strengthening the immune system and protecting against pathogens. It provides excellent foundational immune support.
Vitamin C (1000mg) is crucial for collagen production, wound healing, and protecting skin from UV damage and pollution. This high dose, combined with its antioxidant properties, makes it highly effective for promoting radiant, healthy skin and reducing signs of aging.
Vitamin C is a potent antioxidant that can help reduce systemic inflammation by neutralizing free radicals that contribute to inflammatory responses. The high dose in this product provides significant support for modulating the body's inflammatory pathways.
