About Vitamin C with Flavonoids

Vitamin C is a key nutrient for immune health, collagen production, and antioxidant protection, but its effectiveness is enhanced when combined with flavonoids.

Thorne’s Vitamin C with Flavonoids blends vitamin C with citrus-derived flavonoids to improve absorption and provide comprehensive cellular support. Flavonoids work synergistically with vitamin C to stabilize it in the body while boosting its antioxidant effects.

This powerful combination helps neutralize free radicals, supports the body’s natural defenses, and promotes healthy skin, joints, and blood vessels.

Unlike lower-quality vitamin C supplements, Thorne’s formula is designed for optimal bioavailability and gentle digestion, making it an excellent choice for daily wellness.

With the Busy Holiday Season

Please Allow Extra Time For Prescriptions

The holidays bring us joy, but they also bring us more prescriptions to fill and ship. Our pharmacy continues to work diligently, but an increase in demand may result in slightly longer processing times.

Please consider doing the following:

  • Anticipate and account for the mail system taking a bit longer.
  • Request refills earlier.
  • Keep track of the amount of medication you have left.

Thank you,
ClearSpring Team
