Ascorbic Acid Polypeptide is a vitamin C peptide (protein hydrolisate) complex also known under the trade name Vitazyme® C. Compared with a synthetic vitamin C (L-ascorbic acid), which is unstable in preparations, it has good stability in water solutions and other aqueous systems. It is a free-flowing white-to-cream powder with a light fruity odor whose L-ascorbic acid content is 18 – 23% by mass.
In nature, vitamin C is widespread in the plant and animal kingdoms. Oranges, berries, cherries, and fresh tea are all natural sources of L-ascorbic acid. Naturally occurring vitamin C is bound to water-soluble proteins, peptides, and related compounds, like bioflavonoids.
Scientific studies have shown that the bioavailability of Vitamin C upon oral administration depends on the composition of the preparation. The body does not readily absorb most synthetic ascorbic acid, but when taken with fresh citrus, its bioavailability increases significantly.
Ascorbic acid polypeptide is structurally close to Vitamin C deposits in citruses, so it is one of the most bioavailable, effective, and stable forms of its derivatives used in personal care applications. In addition, it is an edible additive used in the food industry, so it is a safe ingredient for skin care preparations.Thanks to its conjugation with peptides, Ascorbic Acid Polypeptide can penetrate deeply into the epidermis, boost collagen production, protect cells from free radicals, and brighten skin tone. It effectively fights against formed freckles, excessive dark spots, and age spots.
The difference in data from 10 to 1 reflects that the efficiency of the vitamin conjugate (peptide complex) is much higher than that of the synthetic complex component. Studies demonstrate that oral administration of Ascorbic Acid Polypeptide increases plasma levels 24 hours after administration and that ascorbic acid is almost entirely excreted from the body after 6 to 8 hours. Vitamin C plays a vital role in many metabolic processes. Since the human body cannot synthesize it, it must be taken daily.
Vitamin C is necessary for synthesizing hydroxyproline, the precursor of collagen, osteoid, and dentin. Ascorbic acid is also needed for the immune system, wound healing, and to strengthen capillaries, preventing them from becoming brittle and bleeding under the skin. It is a potent antioxidant, skin whitening, and reducing agent.
