Pour la santé cardiovasculaire, tout repose sur le relâchement des vaisseaux sanguins, un processus nommé vasodilatation. C’est ce qui contrôle la circulation sanguine, la tension artérielle, et qui assure que le sang parvient au bout de nos doigts, de nos orteils, et partout ailleurs. Pour assurer que nos vaisseaux sanguins demeurent aussi sains que possible, […]

Français | Español | 中文 When it comes to cardiovascular health, how well your blood vessels relax is everything. This process is called vasodilation. It controls blood flow, blood pressure, and ensures that blood gets to the tips of our fingers, toes, and, well, everywhere else. To ensure that our blood vessels stay as healthy as […]

Cuando hablamos de la salud cardiovascular, la capacidad de los vasos sanguíneos de relajarse es de suma importancia. A este proceso se le llama vasodilatación y es el responsable de controlar el flujo sanguíneo y la presión arterial, y de garantizar que la sangre llegue hasta la punta de los dedos de manos y pies, […]

當涉及到心血管健康時,您的血管能夠放鬆的程度就是關鍵。這一過程稱為血管擴張。它控制血流量和血壓,並保證血液運及您的指尖、足尖,及其它各處。 欲保證我們的血管儘可能健康,我們希望保持這種血管舒張反應。 但首先,了解這一過程如何運作很重要。 由內皮細胞產生的一氧化氮控制血流量 我們的動脈由內皮細胞組成。這些細胞下面分佈著一層控制我們的血管收縮或放鬆的肌肉。當這一肌肉放鬆時,血管擴張。這一肌肉如果放鬆,健康的血流就能保障各處獲得所需的足夠血液量。 負責我們血管舒張的主要分子稱為一氧化氮。一氧化氮由血管內皮細胞對不同刺激做出反應時生成,然後擴散到鄰近肌肉細胞中,為這些細胞傳遞放鬆的信號。有趣的是,一氧化氮實際上是一種弱自由基,換句話說,它有未成對電子。 一氧化氮:是良好的自由基? 我們通常認為自由基不利。但對一氧化氮而言,卻非如此,但這種特性確實使一氧化氮和和血管舒張過程對其他自由基的攻擊而敏感。比如,在我們呼吸的氧氣中一個自由基的反應(稱為超氧化物),和一氧化氮可生成的一種討厭的過氧亞硝酸鹽化合物。 過氧亞硝酸鹽在細胞中肆意破壞,並損傷重要的細胞結構。 一氧化氮和超氧化物反應在以下在兩方面有害:首先,它將一氧化氮從身體中移除,這樣它不再為血管傳遞放鬆的信號。其次,當一氧化氮和超氧化物反應時,它使用兩個相對無害的分子而產生第三種化合物,這種化合物會進一步阻礙健康的心血管功能。 抗氧化劑有助於保護一氧化氮 但您可以對此採取什麼措施呢?抗氧化劑。如果您清除所有其他不良自由基(包括超氧化物)將緩解一氧化氮,使其完成血管擴張的使命,保障重要的血液運輸到身體各處。 欲獲得您需要的重要抗氧化劑,您需要在飲食中攝取許多各種顏色的水果和蔬菜,並考慮在您的飲食中添加葡萄籽精華C100。葡萄多酚有助於支持您的心血管健康,包括通過保護那些良好的自由基來支持身體自然的一氧化氮的生成。* 葡萄籽精華® C100的力量 所以為什麼葡萄籽精華C100是一個好選擇呢?嗯,因為USANA有USANA的方式,我們想看一看科學。我們與波士頓大學醫學院的研究員合作並研究葡萄籽提取物及維生素C補充品的作用,這兩種相同的有效成份均存在於葡萄籽精華C100中。 在我們測量的所有時間點,我們發現普通的補充品對抗氧化保護和微血管功能產生有利影響,因為它支持健康、正常的血管擴張過程。 * 查看這一傳單了解詳情,或訪問usana.com閱讀完整研究。並查看這一新影片以了解更多有關葡萄籽精華C100的信息: 欲獲得最佳心血管健康,您需要正確地飲食、健身,並確保由葡萄籽精華C100幫助您擁有最佳的抗氧化水平。 https://www.usana.com/media/File/dotCom/company/science/crb/CR_GSE_Vascular_Health_Poster.pdf http://www.ncbi.nlm.nih.gov/pubmed/25638487 http://www.pnas.org/content/84/24/9265.short http://www.ncbi.nlm.nih.gov/pubmed/17237348 http://www.jbc.org/content/288/37/26464.abstract Jariwalla RJ, Harakeh S.
