Esterified vitamin C is a supplement formulated to react with an essential mineral, an effect that eliminates the vitamin's usual acidity, sparing your stomach, notes the "Prescription for Nutritional Healing." According to the author, Phyllis A. Balch, your body absorbs esterified vitamin C four times faster than it assimilates standard supplements. Esterified C also lasts longer in your tissues, with only 1/3 of it being flushed when you urinate. Supplement vitamin C under your doctor's advice.
How It Works
In a March 1989 article in "Better Nutrition," Professor Anthony J. Verlangieri, Ph.D., explains that esterified vitamin C is fat-soluble, while the standard vitamin, also called ascorbic acid, is not. Regular vitamin C is water-soluble, which means that the amount you ingest in excess of what your body needs at the moment gets flushed in your urine. Because esterified C is fat-soluble, it stays stored in your body's fatty tissues, providing extended health benefits.
Esterified vitamin C is attached to palmitic acid, a fatty acid, which makes the nutrient fat-soluble. Vitamin C ester is also known as ascorbyl palmitate, a name that combines ascorbic acid and palmitic acid.
Esterified C vs. Ester-C
Ester-C is a registered trademark and not the same as esterified vitamin C, reports the Linus Pauling Institute. Ester-C is a blend of a large amount of calcium ascorbate with a small amount of ascorbic acid. Unlike esterified vitamin C, Ester-C supplements are not stored in fatty tissue in your body. They are water-soluble, and as such are expelled when you urinate.
Benefits of Vitamin C
Vitamin C is vital for healthy vessels, ligaments, tendons and bones. The nutrient also participates in the production of norephinephrine, a chemical that makes it possible for your nerve cells to transmit information. In addition, vitamin C is an antioxidant, a substance that rids your body of disease-causing molecules known as free radicals. You need a consistent supply of antioxidants such as vitamin C because free radicals are constantly forming as a byproduct of digestion and exposure to toxins. Since esterified C stays in your body, it might be more efficient at protecting you from free radicals than regular water-soluble vitamin C.
