Product Overview


  • Immune Support & Synergistic Antioxidants
  • Dietary Supplement

Dihydroquercetin-3-rhamnoside (D-3-R) is a flavonoid and potent water soluble antioxidant that is synergistic with Vitamin C. Unlike many flavonoids, D-3-R is very bioavailable. Professor Szent-Gyorgyi, the recipient of the Nobel Prize for Vitamin C, categorized flavonoids such as D-3-R as "vitamin P," making Vitamin C more biologically active and available.

Colour of the Vitamin C tablets more yellowish

Posted by 5343490377994415012 on May 17, 2016

The colour of the Vitamin C tablet have slightly yellowish compare from my purchase from the clinic Not only different in colour but the hardness is slightly soft too as i will split into two before swallowing them. I do keep them in the fridge but the hardness is still that easy to split into two. hopefully i dont get any fake vitamin C as i consume 10 tablets daily as instructed from my Doctor.
