Vitamin C functions as an antioxidant and a cofactor for enzymes that build collagen and support normal immune cell activity.
Caution: High doses may cause digestive discomfort in some people; take with food if sensitive.
Bioflavonoids provide polyphenols that may help protect cells from oxidative stress and support healthy capillary function.
Caution: May cause mild gastrointestinal upset in sensitive individuals; discontinue if discomfort occurs.
Rutin is a flavonoid that may help reinforce capillary integrity and provide antioxidant activity.
Caution: If you experience stomach upset, consider taking with food.
Hesperidin is a citrus flavonoid that may support vascular comfort and antioxidant defenses.
Caution: Those sensitive to citrus components may prefer to start with a lower intake.
Rose hips supply natural polyphenols and vitamin C-related compounds that may enhance antioxidant support.
Caution: May cause mild digestive discomfort in some individuals; take with food if needed.
Vitamin C provides core antioxidant and collagen-supporting activity, while citrus bioflavonoids, hesperidin, rutin, and rose hips add complementary polyphenols that reinforce antioxidant capacity and microvascular support. The combination covers both water‑soluble antioxidant roles and support for connective tissue and capillary integrity. The sustained release design may help maintain steadier vitamin C levels over time.
