高效能抗氧化配方，蕴含葡萄籽生物类黄酮及专利注册"矿物维生素 C
提供强效抗氧化功能，抵抗游离基对身体造成的破坏
帮助维持微细血管健康及加强血液循环功能
功能·促进心脏血管健康 ·增强免疫能力·改善眼睛健康·具消炎作用·预防皮肤过早衰老
游离基的破坏游离基对身体健康会造成严重破坏。事实上，环境污染、吸烟、饮食及新陈代谢都会产生游离基、因而引致各种退化性疾病的产生。其中一个对抗游离基的最佳方法，是增加摄取各类抗氧化剂，以减少及中和游离基对身体的影响。
游离基杀手 -- 强力抗氧化剂科学家发现超过 20,000 多种生物类黄酮和生物类黄碱有不同程度的抗氧化作用。而前花色素是其中一种含最高抗氧化效能的生物类黄酮。事实上，在很多食物中也可以摄取到前花色素，但含量不多，要单从食物中摄取足够前花色素较为困难。
前花色素能减少游离基对身体的侵害，兼且可以保护及更生维他命 C 和 E 的作用 (维他命 C 和E，两者都是强力游离基清除剂)。配合 USANA 注册专利配方矿物维生素 C ，更能提升葡萄籽精华的强效全面抗氧化功能，促进身体健康。
葡萄籽精华的保健功能世界各地科学家对前花色素都有极高评价，科学文献及研究报告更指出前花色素对身体的改善范围包括：
加强微细血管与血液循环功能，并能改善眼睛健康
增强身体免疫能力
预防皮肤过早衰老及令皮肤回复弹性
有效抑制低密度胆固醇 (LDL) 的氧化，帮助预防心脏病
具消炎作用
USANA葡萄籽精华的特点USANA的高效能抗氧化配方能抵抗游离基对身体造成的破坏，维持微细血管健康 及加强血液循环功能，改善眼睛疲劳，预防皮肤过早衰老及令皮肤恢复弹性，具有消炎作用，并能预防心脏疾病。事实上，脂肪代谢、环境污染、抽烟、饮食及新陈代谢都会产生游离基，从而引发各种退化性疾病产生。

Proflavanol
Every day, free radicals—from environmental pollution, cigarette smoke, fatty diets, and normal cellular metabolism—assault our cells. Proflavanol, with its high concentration of grape-seed extract (30 mg in each tablet) and a healthy dose of USANA’s exclusive Poly C® formulation, supports the body's fight against free-radical damage.*
Supplies a unique antioxidant formula based on a combination of grape-seed bioflavonoids and Poly C
Helps retain sound cardiovascular function, immune function, and circulation*
Provides a first line of defense against oxidative stress*

Plants are living pharmacies, producing thousandsof substances that are beneficial to humanhealth. There are several major categories of thesephytonutrients, including the plant pigments calledbioflavonoids. While clearly exhibiting antioxidantcapabilities that offer protection from oxidative stress,bioflavonoids are probably even more important fortheir ability to modulate cell signaling pathways.Among the many important cell-signaling functionsthat bioflavonoids influence are regulating the cellcycle, inhibiting cell proliferation, and producingdetoxification enzymes.1-5PROANTHOCYANIDINSProanthocyanidins are a subclass of bioflavonoidsfound in blue and purple berries, purple grapes, andred wine, and they are available in relatively highconcentrations in grape-seed extract. Research suggestsa strong role for dietary bioflavonoids, including theproanthocyanidins, in supporting and maintainingsound cardiovascular function.6-8 Epidemiologicalevidence of this connection begins with the observationthat relatively low rates of heart disease exist inFrance, despite a diet high in saturated fat.9 Thisapparent “French paradox” has been attributed to theproanthocyanidins in the red wine consumed withmost meals. Human clinical research has also shownthat proanthocyanidins in red wine maintain healthyendothelial function.10,11*Proanthocyanidins have been studied extensively inEurope and in the United States. Scientifically observedand documented benefits include the following:• Helps protect plasma LDL from oxidation12*• Helps retain healthy capillary strength andvascular function13,14*• Supports healthy immune function15*• Supports healthy peripheral circulation16*Why Pro flavanol® & Pro flavanol® 90?With USANA’s unique formulation, Proflavanol® andProflavanol® 90 bioflavonoid supplements combine thehighest quality grape-seed extract with the free-radicalquenching power of exclusive Poly C® (see page 38),giving you an important tool in the quest for lifelonggood health.17,18 Laboratory studies done at USANAconfirm that, when used together, these ingredientsprovide significantly better protection against theoxidative modification of low density lipoproteins(LDL) than would be predicted from the sum oftheir individual effects. Not only do proanthocyanidinsneutralize free radicals, they also conserve and regeneratevitamins C and E
