維生素C（抗壞血酸）(Vitamin C (Ascorbic Acid)) 500毫克

一般飲食當中大約有90%的維生素C來自新鮮蔬果。椒類尤其富含維生素C，例如綠甜椒、紅甜椒、紅辣椒及綠辣椒。其他良好的食物來源包含柑橘類水果與果汁、球芽甘藍、花椰菜、高麗菜、羽衣甘藍、寬葉羽衣甘藍、芥菜、綠花椰菜、菠菜及草莓。務必注意，烹煮會毀掉維生素C的作用。

維生素C也因此成為全世界最受歡迎的維生素。維生素C的名聲響亮，背後具有不可思議的多重原因。此維生素可以促發身體的眾多機能。*

抗壞血酸以其抗氧化特性而聞名。抗壞血酸可能是體內最重要的水溶性抗氧化物。*

維生素C能增強免疫系統已經是基本常識。為了提高維生素C的攝取量，一個科學專家小組近來建議將目前的維生素C建議攝取量從每日60毫克增加到至少100-200毫克。其次，維生素C可促進正常的肺部健康。維生素C的部分保護作用可能來自於它的抗氧化特性。最後，有些研究指出，補充維生素C有助維護視力健康。*

維生素C以幾種不同的方式支援心血管健康。它有助促進正常的膽固醇值、血壓以及血小板活性，也可促進健康的三酸甘油脂值。藉由清除自由基，維生素C可防止低密度脂蛋白過氧化。維生素C透過促進一氧化氮（又稱為“NO”以及內皮衍生放鬆因子“EDRF”）合成，從而幫維持內皮細胞功能。

如上所述，維生素C有助保存細胞內的還原型穀胱甘肽濃度。此作用可以幫助維持一氧化氮水平並增強其血管活性作用，進而有助維護血管的完整性。*

維生素C可促進攝護腺素合成的正常調節，進而促進正常的血管舒張活性。據上述觀察，維生素C有助維持一氧化氮濃度，並支援其保存血管完整性的能力。有跡象表明，維生素C支援內皮依賴性血管舒張。*

維生素C對維護結締組織的健康很重要，其中包括膠原蛋白、彈力蛋白、纖連蛋白、蛋白聚醣、骨基質、以及與彈力蛋白有關的小纖維蛋白。此外，缺乏維生素C可能造成一般性的疲倦。而且，維生素C對於調節健康的鐵質吸收、輸送及儲存皆有所助益。促進腸道對鐵質正常吸收。*

β-胡蘿蔔素（維生素A前驅物）(Beta Carotene (Vitamin A Precursor)) 800國際單位

維生素A是脂溶性維生素，屬於視黃醇、視黃醛、β-胡蘿蔔素等複合物家族。β-胡蘿蔔素又稱為原維生素A，因為它能轉換成維生素A。維生素A最佳的膳食來源包括動物內臟（例如肝臟和腎臟）、蛋黃、黃油、胡蘿蔔汁、南瓜、紅薯、菠菜、桃子、強化乳製品（例如牛奶和某些人造奶油）、以及鱈魚肝油。

維生素A具有抗老化與抗氧化活性。維生素A有助維護視力，還能促進正常的骨骼生長以及健康的免疫系統。維生素A支援正常的上皮細胞分化、生長、生殖、胚胎模式形成、骨骼發育、造血作用與大腦發育。兒童特別容易受到維生素A缺乏症的影響。*

鉀（碳酸氫鉀）(Potassium (Bicarbonate)) 99毫克

富含鉀的食物包括新鮮蔬果，例如香蕉、橙、羅馬甜瓜、酪梨、生菠菜、高麗菜和芹菜。

鉀是幫助維持體液平衡的必要巨量礦物質。在眾多生化和生理過程中，鉀都扮演重要的角色。除此之外，鉀有助維持正常的神經脈衝傳遞，心臟、骨骼肌及平滑肌的正常收縮，能量生成，合成核酸，維持細胞內張力以及正常的血壓。鉀可促進肌肉放鬆，以及支援正常的胰島素釋放。它還可促進肝糖和蛋白質的正常合成。鉀是一種電解質，可促進正常的心跳，在進行代謝時非常重要，因其可支援蛋白質、脂肪與碳水化合物的適當能量釋放。*

鉀也可促進水分平衡的正常調節，促進體內廢物的正常排除，並有助於提高整體健康。鉀儲存於肌肉中。*

鉀缺乏症的症狀包括血液循環不良、耳朵疼痛、難以入睡、肌肉無力及水腫

鉀與鈉離子是幫助身體維持體體恆定狀態平衡最重要的兩種離子。*

維生素C的每日建議攝取量是多少？

成年男性每日建議攝取量為90毫克，成年女性為75毫克。

Isotonix維生素C粉末是否提供足夠的每日建議攝取量？

是的，Isotonix維生素C粉末每份含有500毫克維生素C，是維護免疫系統的最佳分量。生病或是心情低落時，補充較高食用分量的維生素C有助改善症狀。*

Isotonix維生素C粉末可以增強我的免疫系統嗎？

是的，實際上在多方面都有功效。今天，維生素C已被公認為可能是最佳的免疫系統支援者和抗氧化物。每天食用維生素C可以支援免疫系統功能。維生素C支援免疫系統，保護身體免受自由基的損害。作為一種水溶性維生素，抗壞血酸在血液和細胞內的水性部位執行其抗氧化功能，有助修復維生素E（一種脂溶性抗氧化物）的潛在抗氧化能力。支援免疫系統功能也是維生素的關鍵作用之一。*

Isotonix維生素C粉末對兒童及其脆弱的身體系統是否安全？

兒童應該食用DNA Miracles Isotonix^®兒童多維素粉末，該配方每份食用量中的維生素C含量較低。維生素C營養補充品對兒童有特別的好處。*

哪些人需要補充Isotonix維生素C粉末？

基本上，年滿18歲的人都應該食用Isotonix維生素C粉末以在飲食中增加維生素C，因為我們極少有人從每日飲食當中攝取到建議分量（5份）的蔬果。需要特別補充維生素C的族群包括銀髮族、免疫力較弱的人、吸菸者、壓力大的人、有心血管問題的人以及運動員。*

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？

本產品有助維持膽固醇與三酸甘油酯值的正常水平，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。最後，維生素C支援正常的血小板活性。*
