挑選最優質的營養補充品時，最重要的兩個元素是吸收和效用。Isotonix系列的營養補充品與水混合時，可達到與體液（如眼淚、血漿及血液）一樣的酸鹼度和滲透壓。所有食物必須轉化成等滲透狀態，營養才能有效地被人體吸收。這耗時的過程可能長達三小時，會限制人體吸收營養。Isotonix維他命C沖飲與市場上的其他產品截然不同，能在最短時間內讓人體最有效地吸收營養。

Isotonix維他命C沖飲以最有效的方式輸送人體所需的營養。英國利茲大學、倫敦蓋伊醫院、貝勒大學和梅奧診所等的研究均指出，等滲透配方不但能令營養更快離開胃部，而且滲透壓能控制胃排空速度，使身體各個系統更有效地吸收營養。Isotonix維他命C沖飲能為你的免疫系統提供所需支援。

我們大部分人都沒有每天進食建議的五份蔬菜和水果，因此無法單靠日常飲食吸收75-90毫克的維他命C建議攝取量。每天使用Isotonix維他命C沖飲能確保你獲得每日所需攝取量。年老、免疫系統衰弱、吸煙、壓力沉重、患有心血管疾病的人士及運動員尤其需要補充維他命C。

Isotonix®輸送系統

---

Isotonix系列產品是最有效的輸送營養補充品之一。配方採用先進和經科學證實的成分，提供高效輸送及卓越的效果。 

Isotonix為等滲壓的原因是因為產品與人體內的液體相同，含有幾乎相同的濃縮可溶物，如盬、糖及礦物質。在此濃度下，營養及分子便能有效地通過細胞壁，用作細胞代謝。Isotonix產品配方中的果糖、葡萄糖、檸檬酸、碳酸氫鉀及其他主要成分搭配均衡，以確保正確調配飲用時達到等滲狀態。

 

Isotonix產品以適當的比例與濃度傳送營養素，以達致最佳的吸收。Isotonix是市場上經科學證實最有效的營養傳輸系統之一。

成份

維他命C
含有最豐富維他命C的食物包括柑橘類水果（橙、西柚、檸檬和柑橘）、士多啤梨、蕃茄、西蘭花、小椰菜、椒類和哈密瓜。維他命C是一種「脆弱」的維他命，容易因烹煮或接觸氧氣而受到破壞。

維他命C促進維他命「節約」效應，讓人體能更有效地使用多種維他命和礦物質，包括硫胺、核黃素、泛酸、生物素、葉酸、維他命B12、維他命E和鈣。它亦是葉酸、部分氨肌酸和荷爾蒙的輔因子或輔助劑，並為膠原蛋白合成的輔因子，有助鞏固新生的膠原蛋白。維他命C支援心血管健康和免疫系統，而其部分防護作用似乎來自其抗氧化功能。

維他命C以多種方式協助支援心血管健康。它或有助於穩定血脂和血壓。它亦可促進一氧化氮的合成，從而有助維持內皮細胞功能。維他命C有助維持一氧化氮水平，從而支援其保護血管完整性的能力。* 

維他命C在維護健康的結締組織方面擔當關鍵角色，這些結締組織包括膠原蛋白、彈力蛋白、纖維連接蛋白、蛋白聚糖、骨基質和彈性蛋白相關原纖維蛋白。

維他命C是世界上最多人使用的維他命補充品。人體無法製造維他命C，因此需要透過補充品攝取。維他命C最廣為人知的功能是其抗氧化能力，而它更可能是人體內最重要的水溶性抗氧化物。基於其水溶性質，維他命C會每天排出體外。由於人體未必能夠從飲食攝取充足的維他命C，因此使用補充品對人體有益。

β-胡蘿蔔素（維他命A前驅物）
維他命A是脂溶性維他命，為視黃醛、視黃醇及β-胡蘿蔔素化合物家族的成員。β-胡蘿蔔素能轉化成維他命A，因此又稱為維他命A原。它具有抗氧化功能、有助鞏固視力，並能促進正常的骨骼成長及免疫系統健康。維他命A支援表皮細胞分化、成長、繁殖、胚胎形成時的模式形成、骨骼發育、造血作用及腦部發育。

常見問答

---

維他命C的每日建議攝取量是多少？ 
一般成年男性為90毫克，而成年女性則為75毫克。

Isotonix維他命C沖飲可以提供每日建議攝取量嗎？
可以，Isotonix維他命C 沖飲每一使用份量含有500毫克維他命C。在生病或受壓時，增加攝取維他命C或會有所幫助。

Isotonix維他命C沖飲有助支援我的免疫系統嗎？
是的，維他命C現被視為可能是最有效支援免疫系統的營養和最強效的抗氧化物。維他命C能保護人體免受自由基的損害，從而支援免疫系統。這種水溶性維他命在血液和細胞液內發揮抗氧化功能，並有助修復維他命E（脂溶性抗氧化物）的潛在抗氧化能力。*

甚麼人需要Isotonix維他命C沖飲？ 
任何18歲以上人士都需要Isotonix維他命C沖飲，其中年老、免疫系統衰弱、吸煙、壓力沉重、患有心血管疾病的人士及運動員尤其需要補充維他命C。

有可能會使用過多的Isotonix維他命C沖飲嗎？
維他命C在相對較高的水平也是非常安全的（因大部分剩餘的維他命C會透過尿液排出）。使用高劑量時（每日超過1000 毫克），有些人的消化道會出現副作用，如胃痙攣、噁心和腹瀉。 

Isotonix維他命C沖飲怎樣有益心血管健康？
Isotonix維他命C沖飲或有助於穩定血脂和膽固醇。它能促進動脈壁強壯，並有助身體維持對心血管系統有益的維他命E水平。*

怎樣使用Isotonix維他命C沖飲？
將一小瓶蓋（白色螺旋蓋）的粉末倒入透明瓶杯中，加水至瓶杯線上（2安士/60毫升），攪拌後飲用。本品為營養補充品，每天飲用一次或按醫護人員指示飲用。空肚飲用時效果最佳。使用規定量的粉劑與水混合才會使本產品達到等滲狀態。

本產品是否標示「不含可檢測出之基因改造生物」？ 

本產品未檢測出基因改造生物。本產品的原材料中或許含有基因改造的材料/成份，但其最終產品並不含任何轉殖基因片段或轉殖蛋白質。

使用Isotonix維他命C沖飲安全嗎？
Isotonix維他命C沖飲安全及不含有害物質。此產品在美國製造，並於經美國食品及藥物管理局檢測的設備生產，符合良好生產規範。顧客對本產品的質量和安全可絕對有信心。
