1. Boosts Immune System: Buffered Vitamin C Plus contains essential nutrients that help boost the body's immune system. It helps in the production of white blood cells, which are responsible for fighting off infections and diseases.
2. Powerful Antioxidant: Vitamin C is a potent antioxidant that helps protect cells from damage caused by harmful free radicals. Buffered Vitamin C Plus provides a buffered form of vitamin C, making it easier for the body to absorb and utilize this powerful antioxidant.

The Active Ingredient Is: Vitamin C (Ascorbic Acid)

Vitamin C, or ascorbic acid as some call it, is a water-soluble vitamin that your body uses for normal function and antioxidant protection. This formula pairs vitamin C with buffering minerals to help with tolerance for sensitive stomachs.

Form and source details point to a buffered ascorbate linked with minerals like calcium, magnesium and potassium, which aid absorption and nutrient compatibility. This blend also includes citrus bioflavonoids and citrus pectin to boost antioxidant protection.

What Does Vitamin C Do?

Vitamin C helps with normal collagen synthesis and shields cells from oxidative stress, aligning with EFSA and NHS guidance on heart and connective tissue health. It also supports immune function as part of a balanced diet, with bioflavonoids possibly helping vitamin C uptake.
