維他命A（β-胡蘿蔔素）
維他命A於抗衰老微量營養素當中排列第一位，與維他命C、E及礦物質硒一起穩固地保持健康。近年研究所得，β-胡蘿蔔素對於維持身體整體健康扮演著重要的角色。β-胡蘿蔔素作為維他命A的前體，也被稱為維他命A原。當身體需要維持健康肌膚、視力及免疫系統的必需品時，β-胡蘿蔔素可被身體轉換成維他命A 。

維他命C
同時被稱為抗壞血酸。維他命C有助支援及維持皮膚內的健康骨膠原、身體正常自癒力、健康的牙齒與骨骼及免疫系統。維他命C是一個強效且常見的抗氧化物。就如切開的蘋果與空氣接觸後迅速變成咖啡色一樣，身體的細胞暴露在空氣下一樣會受到氧化的影響。氧化會導致肌膚衰老，當然也包括身體所有的器官和組織。維他命C，作為自由基的對抗者，幫助身體長久保持年輕。

維他命E
維他命E支援呼吸系統健康。同時亦促進健康免疫系統。正常老化過程中，氧氣會破壞身體的組織，維他命E可幫助身體抵禦氧化的傷害。維他命E中和自由基。自由基本身是不穩定的分子，會破壞身體健康的分子，搶奪其電子以取得自身平衡。當體內有充足的維他命E，不穩定的自由基會由維他命E中取電子，而不會傷害健康的分子，因此促進組織健康。

硒
硒是最重要的微量營養素之一，包含在長壽健康的食療中，及時常被抗衰老專家用作抗氧化物成分之一。硒和另一個強效抗氧化物 – 維他命E ， 可產生協同作用，意思是指兩者可互相促進另一營養素對身體的健康效果。硒更可促進穀胱甘肽過氧化物酵素的產生，穀胱甘肽過氧化物酵素是身體主要的抗氧化物。硒是重要的微量礦物質，與維他命E密切合作，提供身體防禦自由基的抗氧化防護。硒以兩種方式保護身體抵抗自由基：硒與蛋白質結合，產生對抗氧化酵素非常重要的硒蛋白；硒支援身體產生天然的抗氧化物 – 穀胱甘肽。

歐洲藍莓
歐洲藍莓的主要作用在於與維他命E產生協同作用，並成為強大的抗氧化物。一般的情況下，它能支援微絲血管的正常阻力並促進其不滲透的本質。歐洲藍莓花青素也支援重要酵素於視網膜細胞的代謝與功能的運作。同時亦支援健康心臟。歐洲藍莓促進正常血小板活動。

綠茶萃取物
綠茶萃取物是促進健康的抗氧化物。綠茶萃取物富含多酚，可促進健康。

銀杏葉
銀杏葉幫助支援記憶力、大腦功能、情緒、大腦及周邊血液循環，氧含量及血流量。　　

奶薊草
用於促進肝臟健康。奶薊草包含數種已知最強效的保護肝臟物質。奶薊草可發揮抗氧化能力，保護肝臟抵禦自由基的侵襲，亦可支援肝臟新細胞的正常生成。

甚麼是自由基？
一般情況下，份子的連結並不會分開，形成單數或未配對電子。但是，當較弱的連結斷開，便會形成自由基。自由基極度不穩定，會與其他複合物迅速作出反應，從而奪取所需的電子來回復穩定。一般來說，自由基會攻擊最接近自己的穩定分子，盜取它的電子。當受攻擊的分子失去它的電子，它就會變成自由基，產生一連串的連鎖效應。當效應一旦開始，便會有一連串反應發生，最後導致細胞受破壞。

一些自由基會在新陳代謝中正常增長。有時候，身體的免疫系統細胞會有目的地製造自由基以中和體內的病毒和細菌。然而，環境因素如污染、幅射、吸煙、除草劑亦會產生自由基。

身體多數時間可以處理自由基，但如果沒有抗氧化物，或當自由基的數量過多，就會產生氧化作用。更重要的是，由自由基而產生的氧化作用會隨年齡增長而累積。

抗氧化物如何對抗自由基？
維他命C及E被認為能保護身體，抵抗由自由基帶來的負面影響。抗氧化物透過提供自己的一顆電子以中和自由基，停止自由基的盜取行為。抗氧化營養素自身不會因貢獻出電子而變成自由基，原因是它們在任何一個形態下均能保持穩定。它們作為清除角色，幫助中和自由基。

維他命E是體內最有效的脂溶性抗氧化物之一。它是最有效、能中斷連結的抗氧化物之一。它是抵擋氧化及脂質過氧化（產生比平時更高含氧量的不穩定分子）的第一道防線。

維他命C是體內最豐富的水溶性抗氧化物之一。它的主要作用見於細胞液中。用於對抗因污染及吸煙而產生的自由基特別有效。它也能幫助維他命E重回活躍的狀態。

甚麼食物含有抗氧化物？
蔬果含有豐富的抗氧化物。問題在於處理蔬果的過程中，大多數的抗氧化物會被移除。因此，即使進食大量蔬果也不能確保你攝取足夠的抗氧化物。然而，這是一個好開始。

甚麼是最佳的抗氧化物？
對抗自由基的最佳方法是集合各種抗氧化物。沒有任何一種抗氧化物特別有效。以確保效用，各種抗氧化物需互相配合以發揮功效。你會發現使用多種抗氧化物的營養補充品，相比只攝取部分抗氧化物，會有更佳的效果。
