The Science Inside

How It Works: Most vitamin C supplements use a single form of ascorbic acid. Ultra Potent-C® 1000 combines ascorbic acid with mineral-based forms of vitamin C (like calcium ascorbate and sodium ascorbate) to reduce acidity, which is why it’s easier to digest.* By using multiple forms of vitamin C, along with key nutrients, this formulation supports your body's ability to absorb and use these compounds.*

Key Ingredients:

• Vitamin C (1,000mg): Delivered as a buffered blend of multiple ascorbate forms for a more balanced approach to high-dose supplementation.
• Citrus Bioflavonoid Complex (32mg): Plant compounds naturally found in citrus fruits that work alongside vitamin C, both in nature and in this formula.
• L-Lysine (33mg) and L-Cysteine (8mg): Amino acids that complement vitamin C.
• L-Glutathione (5mg): One of the body's most important antioxidants, included to complement the overall formula.*
• Niacin (70mg): A B vitamin that supports energy metabolism.
