合成維他命與食品來源維他命

儘管合成維生素 C 和食品來源的維生素 C 的化學性質相同，但水果和蔬菜含多種豐富營養素和植物化學物質，可能會影響其生物利用度。

Although synthetic and food-derived vitamin C is chemically identical, fruit and vegetables are rich in numerous nutrients and phytochemicals which may influence its bioavailability.

所有人體生物利用度研究均表明，無論受試者群體、研究設計或介入如何，合成維生素 C 和天然維生素 C 之間沒有差異。

All steady state comparative bioavailability studies in humans have shown no differences between synthetic and natural vitamin C, regardless of the subject population, study design or intervention used.

Phytochemical: a chemical compound occurring naturally in plants.

Bioavailability: the degree and rate at which a substance is absorbed into a living system or is made available at the site of physiological activity.
