Vitamin C’s popularity is undeniable—and so are its benefits! Vitamin C with Dihydroquercetin is a unique formulation that combines high-quality vitamin C with dihydroquercetin (a flavonoid antioxidant), which has been shown to boost vitamin C levels and aid your body in recycling vitamin C. When you’re ready to supercharge your daily vitamin C supplement, pick up a bottle of Vitamin C with Dihydroquercetin.

  • A powerful antioxidant and free radical scavenger
  • Protects the body from oxidative stress
  • Essential to the formation of collagen
  • Promotes healthy iron absorption
  • Protects against multiple environmental stresses
  • Lasts longer in the body than typical vitamin C formulations

Natural Ways to Boost Vitamin C

The benefits of vitamin C are well known to nutritional researchers. Since its isolation more than 80 years ago, thousands of research studies have shown that vitamin C is a powerful antioxidant that scavenges free radicals, provides protection from oxidative stress, and delivers profound whole-body health benefits.1-8 It has been shown to:

  • Promote the absorption of iron while simultaneously inhibiting its oxidation.9,10
  • Aid in the formation of collagen, the connective tissue that supports arterial walls, skin, bones, and teeth.4-6
  • Protect the body from the effects of stress.11-15
  • Play a vital protective role against physical and environmental stresses such as ingestion of heavy metals,16-21 cigarette smoking,22-25 compromised immunity,26-33 and extreme temperatures.21,34-36

Vitamin C is an essential nutrient, meaning humans can’t create it internally. Instead, we must get all of our vitamin C from diet or supplements. Unfortunately, vitamin C is also water soluble, meaning that it’s quickly oxidized and released inside the body. Until now, the best way to maintain optimal blood levels of vitamin C was to consume it multiple times throughout the day.

Vitamin C with Dihydroquercetin solves this problem through the addition of the flavonoid antioxidant known as dihydroquercetin. This unique molecule has been shown to “supercharge” vitamin C by slowing down its oxidation and elimination from the body. The result is more stable and longer-lasting blood levels of vitamin C, plus the antioxidant benefits of dihydroquercetin itself.37-39 This synergistic relationship greatly enhances the efficacy of both molecules in the body’s organs and tissues.40-43 If you’re ready to supercharge your vitamin C program, add Vitamin C with Dihydroquercetin to your daily supplement regimen.
