維生素C是全球最受歡迎的維生素產品

維生素C（抗壞血酸）(Vitamin C (ascorbic acid))是重要營養素之一，提供強效抗氧化，且支援免疫健康。維生素C是效力強大的水溶性抗氧化物，在細胞層級為身體提供保護。它對抗血液及細胞內的氧化壓力，有助於恢復並提升抗氧化能力，如維生素E，並支援健康免疫反應及心血管功能。

常見問題

哪些人需要補充Isotonix維生素C粉末？
年滿18歲的任何人都可以食用Isotonix維生素C粉末以在飲食中增加維生素C，因為我們極少有人能從每日飲食當中攝取到建議分量（5份）的蔬果。
是否有可能食用過量的Isotonix維生素C粉末？
即使抗壞血酸水平相當高，其實也是非常安全的（因為大部分的過量抗壞血酸會隨著尿液排出體外）。在高量攝入（超過1000毫克/每日）時，有些人可能會出現腸胃道副作用，例如胃痙攣、噁心和腹瀉。為最大獲益於維生素C，建議在一天當中以逐漸增加食用分量的方式來食用維生素C營養補充品。*
Isotonix維生素C粉末如何有助於心血管健康？
它有助維持正常的膽固醇和三酸甘油酯水平、促進健康的動脈壁，並支援正常的血壓。有助人體維持對心血管系統有益的維生素E水平。最後，維生素C支援正常的血小板活性。*
儲存該產品的最佳方式是什麼？
請將Isotonix產品放置於乾燥、陰涼處。將Isotonix產品存放於廚房時，請遠離爐具、水槽、任何發熱設備或窗台。如果您居住的區域非常潮濕，您可以將Isotonix產品儲存在冰箱中，但是不要放在蔬果區。
