Life Extension Fast-C with Dihydroquercetin offers faster absorption than other supplements without greater excretion. It neutralizes free radicals and supports arterial walls, skin and bones. It also supports the immune system and helps other antioxidants.

Vitamin C efficacy can be limited because it is quickly utilized and excreted by the body.1 A novel formula sets a new standard for rapid absorption, enhancing the time that vitamin C is delivered for cellular protection.

In two human trials at a distinguished research center, FAST-C® was compared head-to-head with a leading premium brand of “enhanced absorption” vitamin C.2,3 Their findings validate that FAST-C® has faster absorption - and without greater excretion.

Vitamin C neutralizes free radicals,4-7 supports biosynthesis of certain neurotransmitters,8,9 and promotes production of vital tissue (collagen) that supports arterial walls, skin, and bones.7-9 Vitamin C promotes immunity,7,10 boosts lymphocyte glutathione levels,11 and helps regenerate other antioxidants, including vitamin E.12

But because it leaves the body quickly,1 capturing vitamin C’s optimal benefits has required taking supplements several times daily, hoping they’ll be effective without posing a risk for acid-sensitive stomachs. The scientific community has long sought faster-absorbing vitamin C formulas.

A leading brand of “enhanced” vitamin C has been promoted claiming to increase vitamin C bioavailability. A published study in a top nutritional sciences journal found no difference in absorption speed, blood vitamin C increase, or urinary excretion between that product and ascorbic acid (vitamin C).13

The good news? A next-generation FAST-C® supplement has been proven in double-blind, human trials to have faster absorption - combined with equal or greater body retention. It also contains dihydroquercetin to enhance vitamin C’s “recycling” power.

FAST-C® with Dihydroquercetin is the only vitamin C product to incorporate:

  • A proprietary blend of alkalizing minerals that yields an almost completely acid-neutralized (which is better than “buffered”) vitamin C for sensitive stomachs
  • Piperine (Bioperine®), a multipatented, black pepper alkaloid that significantly accelerates vitamin C absorption, shortening the time to peak plasma concentration3
  • Dihydroquercetin, a grape leaf derived flavonoid that donates electrons back to vitamin C molecules that have spent their electrons neutralizing free radicals - regenerating vitamin C to work again14

In recognition of this breakthrough, FAST-C® received the prestigious Scientific Achievement Award from Nutrition Business Journal.15

In a soon to be journal-published article, scientists evaluated the FAST-C® formulation in humans. They found that in just 60 minutes the FAST-C® composition generated a “significantly higher” vitamin C blood increase than the leading, enhanced-absorption vitamin C product.2 To further validate these findings, a second clinical trial was conducted to compare two different variations of the formula in FAST-C® with the leading, “enhanced” brand.

One of the FAST-C® formulations produced higher blood concentrations of vitamin C after 30, 60, and even 90 minutes. Despite faster and greater rises in blood vitamin C with FAST-C® the amounts of vitamin C excreted in the urine were no greater than the amount excreted in the urine with the leading “enhanced” brand - which suggests similar or better vitamin C retention by the body.3
