Key Benefits

• Supports your immune system when you need it most.

• Helps maintain healthy skin, bones, and connective tissue.

• Protects your cells from everyday oxidative stress.

• Contributes to reducing tiredness and fatigue.

Start each day with confidence—Vitamin C is vital for your immune system and helps keep your skin, bones, and blood vessels in good shape. Since your body can’t make vitamin C, a daily supplement is a simple way to help fill the gap.

Thorne’s Vitamin C with Flavonoids brings together ascorbic acid and naturally occurring citrus bioflavonoids in a convenient capsule. This thoughtful blend supports your immune defences, helps maintain healthy collagen for skin and joints, and contributes to reducing tiredness—so you can keep up with life’s demands. Add it to your routine and help your body stay resilient, inside and out.

Unlike other Vitamin C supplements that rely solely on ascorbic acid, Thorne’s Vitamin C with Flavonoids includes naturally occurring citrus flavonoids. These flavonoids enhance the antioxidant properties of Vitamin C, boosting its ability to scavenge free radicals and support the body’s defence against oxidative stress. This powerful combination not only supports immune health but also improves the overall antioxidant capacity in the body. With Thorne’s Vitamin C with Flavonoids, you can strengthen your body’s natural defences more efficiently and maintain better long-term health.
