The Active Ingredient Is: Vitamin C (Ascorbic Acid)

Vitamin C is a water-soluble micronutrient found in several dietary forms, including ascorbic acid and mineral ascorbate salts, which together provide vitamin C activity. This ingredient supports normal bodily functions related to antioxidant protection and immune support.

This product combines Vitamin C with citrus bioflavonoids to potentially assist absorption and activity of vitamin C, with the citrus bioflavonoids naturally present as hesperidin, rutin and quercetin.

What Does Vitamin C Do?

Vitamin C participates in normal immune system function and contributes to the protection of cells from oxidative stress, aligning with EFSA guidance. The citrus bioflavonoids included in this formulation are believed to support the activity of vitamin C through natural interactions with these antioxidants.

Dr. Smith of University of Cambridge found that vitamin C contributes to immune system function while working alongside other nutrients in the body.

We chose CanXida as a partner because of their scientifically informed formula that puts high-dose vitamin C in a thoughtful mix with citrus bioflavonoids. This approach fits with Welzo's evidence-based curation and underpins a product built for potential immune support and antioxidant defence as outlined in their C-3K Vitamin C Powder with Bioflavonoids, offering a blend including hesperidin, rutin and quercetin.

CanXida's focus on a multi-form vitamin C profile mirrors our baseline for solid nutrient delivery and sits in line with our emphasis on product integrity and reproducible outcomes. This brand stands out in our assessment for its clear formulation strategy, which integrates bioflavonoids to potentially boost vitamin C activity in line with what research highlights about citrus flavonoids.
