„随着年龄增长,我们产生 NO 的能力会下降。事实上,从十几岁后期和二十岁出头开始,每十年大约下降 10–12%。如果你超过 40 岁,即使没有任何临床症状,也无疑需要一氧化氮。一氧化氮的减少,是多种年龄相关慢性疾病发生和进展的首要事件。”As we age we lose our ability to produce NO. In fact about 10-12% every ten years starting in our late teens and early 20s. If you are over 40, no doubt you need nitric oxide even if you don’t have any clinical symptoms. Loss of nitric oxide is the first event in the onset and progression of a number of age related chronic conditions.
„一氧化氮的减少,是多种年龄相关慢性疾病发生和进展的首要事件。在出现任何缺乏症的临床体征前,你可能已经缺乏 NO 好几年。最好的保障措施,是在出现重大健康问题之前,开始使用安全有效的一氧化氮产品。”Loss of nitric oxide is the first event in the onset and progression of a number of age related chronic conditions. You could be deficient in NO for a couple of years before you develop any clinical signs of deficiency. The best insurance policy you can have is to start a safe and effective nitric oxide product before any major health conditions.
„这解释了一氧化氮为何以及如何成为一种强效抗氧化分子,因为它能中和有毒、有害的氧自由基。有些人认为,由于包括硝基酪氨酸在内的一氧化氮代谢物总是出现在疾病中,所以一氧化氮会导致疾病。”This explains why and how nitric oxide is a potent antioxidant molecule because it neutralizes toxic damaging oxygen radicals. Some people argue since nitric oxide metabolites, including nitrotyrosine are always present in diseases, that it is causing the disease.
„细胞内的一氧化氮能提高将氧转化为细胞能量的效率。
如果一氧化氮不足,这一过程就会产生大量“氧化应激”和有毒氧自由基。
这种效率低下的氧代谢可能导致慢性疲劳综合征、低 pH、低氧以及细胞内发酵。”Nitric oxide inside the cell increases the efficiency of oxygen conversion to cellular energy.
Without sufficient nitric oxide, this process creates a lot of “oxidative stress” and formation of toxic oxygen radicals.
This inefficient oxygen metabolism can lead to chronic fatigue syndrome, low pH, low oxygen and fermentation inside the cell.
„一氧化氮是人体自然产生的一种分子。它是一种自由基,也就是说,它的最外层分子轨道上有一个未配对电子。一氧化氮倾向于提供这个未配对电子,使自身更加稳定。有些自由基,例如氧自由基,会从一氧化氮和其他分子中夺取电子,从而引发氧化。”Nitric oxide is a naturally produced molecule in the human body. It is a free radical, which means it has an unpaired electron in its outer molecular orbit. Nitric oxide likes to donate its unpaired electron to make it more stable. Some free radicals like oxygen radicals will steal electrons from nitric oxide and other molecules causing oxidation.
结果: 此外,我们使用多种小鼠模型发现,虽然肠道菌群组成会在衰老过程中显著变化,但将粪便菌群移植给老年小鼠,并不能保护其免受与衰老相关的小肠肠道屏障功能障碍的影响。相反,衰老小鼠小肠中的肠道 NO 稳态和精氨酸代谢发生了变化,这一过程由精氨酸酶和 NO 合成所介导。使用精氨酸酶抑制剂 norNOHA 治疗,可预防与衰老相关的肠道屏障功能障碍和低度内毒素血症,并推迟外周组织(如肝脏)衰老的开始。肠道精氨酸和 NO 代谢可能成为预防衰老相关肠道屏障功能障碍,以及由此导致的功能衰退和“炎症性衰老”的目标。
结果: 不过,由于研究设计、干预时长、剂量方案、参与者特征各不相同,且样本量较小,目前还无法确切证实其对心血管健康的显著益处,尤其是对血压的影响。此外,大多数试验是在较年轻或年龄混合的群体中开展的,针对老年人的证据有限。因此,需要在老年人群中开展随机对照试验,以确定补充 BE 的临床意义。现有证据仍属初步,主要用于提出假设,还不足以支持将 BE 作为促进健康老龄化的策略。

„这种营养分配优先级失衡会导致氧化和炎症损伤不断累积、线粒体衰退以及衰老加速,并在临床上表现为癌症、动脉粥样硬化性心血管疾病(ASCVD)、糖尿病和神经退行性疾病 [19,76-78]。HDIVC 可直接纠正这种分配失衡:补充:它能迅速恢复细胞内抗坏血酸水平,使其远超膳食摄入所能达到的范围,补足长期被优先分配消耗的营养素。修复:它能重新激活 DNA 去甲基化(通过 TET 酶),促进胶原蛋白和肉碱合成,并使一氧化氮信号传导恢复正常。氧化还原平衡:它能提供电子,使谷胱甘肽和维生素 E 再生,重新建立抗氧化缓冲能力。”This nutrient triage leads to cumulative oxidative and inflammatory injury, mitochondrial decay, and accelerated aging-manifesting clinically as cancer, ASCVD, diabetes, and neurodegeneration [19,76-78]. HDIVC directly reverses this triage imbalance: Repletion: It rapidly restores intracellular ascorbate far beyond dietary limits, replenishing a chronically triaged nutrient. Repair: It reactivates DNA demethylation (via TET enzymes), enhances collagen and carnitine synthesis, and normalizes nitric oxide signaling. Redox rebalance: It donates electrons to regenerate glutathione and vitamin E, reestablishing antioxidant buffering capacity.
