Frequently Asked Questions (FAQs)

Q1:What’s the difference between UV-standardized and HPLC-standardized Citrus Bioflavonoids?
Q2:How might citrus bioflavonoids enhance the effects of vitamin C?
Q3:Which citrus fruits are the main sources of bioflavonoids?

The main difference between is in accuracy and specificity. UV methods measure total flavonoids by light absorbance, offering a quick and low-cost estimate but with lower precision. HPLC methods are preferred for products requiring precise identification and quantification of active compounds.

Citrus bioflavonoids may work in harmony with vitamin C to enhance antioxidant defense, and may support normal collagen formation, which contribute to healthy skin.*^[6-7]
