1. Oranges: The Vitamin C & Collagen Catalyst

The recommendation to eat one orange on an empty stomach for 14 days focuses on high-bioavailability Vitamin C.

  • Collagen Synthesis: Vitamin C (ascorbic acid) is a mandatory cofactor for the enzymes prolyl hydroxylase and lysyl hydroxylase, which stabilize the collagen molecule. Without it, your skin cannot maintain its structure, leading to sagging and dullness.

  • Bioavailability on an Empty Stomach: While Vitamin C is absorbed well regardless of food, consuming it first thing in the morning with the fruit’s natural water content helps hydrate cells that have been dehydrated overnight.

  • Antioxidant Shield: Oranges contain flavonoids like hesperidin, which improve microcirculation. This is likely the cause of the β€œawake” and β€œbright” look mentioned; better blood flow to the capillaries in the face results in a natural glow.
