Vitamin C with Quercetin

Name: Thorne Vitamin C with Quercetin
Brand: Thorne
Rating: 8.5 (1 reviews)

Immune support, antioxidant protection, general wellness.. The product provides a good dose of Vitamin C with synergistic bioflavonoids. However, it completely lacks Quercetin despite its name. This mislabeling is a significant concern, but the actual ingredients are dosed adequately.

8.5/10

EXCELLENT

Vitamin C at 500mg hits the optimal dose exactly. The product name mentions quercetin but actually contains citrus bioflavonoids at 75mg, which is a different (though related) compound. For vitamin C delivery, this is excellent. The bioflavonoids serve as support to enhance C absorption. As a vitamin C supplement, it delivers perfectly on its purpose at clinical dose from a trusted brand.
