Vitamin C is the 'muscle' of the immune system
2014年2月21日，Thomas Levy 托马斯·利维博士大量的研究(大部分发生在半个多世纪以前)已经明确表明，大量服用和服用维生素C可以治愈大多数急性感染，无论是病毒感染还是其他疾病，并能迅速中和大多数接触到的毒素——包括许多危及生命的健康问题。实际上，维生素C不仅仅是一种抗氧化剂。为什么主流医学拒绝接受维生素C的救生能力还不清楚。
红细胞的维生素C浓度与周围的血浆大致相同。心脏细胞和肾脏细胞是新陈代谢活跃的细胞，它们的维生素C含量是血浆的13倍，这是一个惊人的浓度差异。这肯定与 这些活性细胞对电子的持续需求是一致的。吞噬白细胞(粒细胞)的维生素C含量是血浆的25倍。由于这些细胞需要大量的能量来 清除和消化病原体和细胞“碎片”，这种维生素C的浓度也很有意义。然而，维生素C集中器之王是循环单核细胞，另一种具有吞噬功能的细胞，当它进入组织时。与血浆相比，这个细胞中维生素C的浓度增加了80倍以上。很少(如果有的话)有其他的循环营养素/维生素如此有选择地集中在特定的细胞类型的例子存在。
Vitamin C is the 'muscle' of the immune system
February 21, 2014 by Dr. Thomas Levy
A very large body of work, much of it taking place over a half-century ago, has clearly established that the vigorous dosing and administration of vitamin C can cure most acute infections, viral or otherwise, and promptly neutralize most toxin exposures - including many life-threatening health issues.
Behind the scenes, vitamin C is more than 'just' an antioxidant. Why mainstream medicine refuses to embrace the life-saving abilities of vitamin C remains unclear. But, the validity of the scientific data is absolutely inescapable.
The inescapable truth about avoiding disease
One fact that all doctors and all lay persons agree on is that a strong immune system is key to recovering from an infection, neutralizing and eliminating a toxin, and bringing diseased cells back to a state of good health. There also is no dispute that a competent immune system is the best way to keep a disease from developing and taking hold in the first place.
Therefore, anything that clearly strengthens the immune system and improves its ability to achieve these goals should logically be embraced as well by both the caregiver and the patient.
Vitamin C and the immune system
In addition to its role as the premier antioxidant circulating throughout the body, the scientific literature has clearly established vitamin C to directly promote and stimulate a number of very important functions of the immune system. These functions include the following:
1. Enhanced antibody production (B-lymphocytes, humoral immunity)
2. Enhanced interferon production
3. Enhanced phagocytic (scavenger cell) function
4. Enhanced T-lymphocyte function (cell-mediated immunity)
5. Enhanced B-lymphocyte and T-lymphocyte proliferation6. Enhanced natural killer cell activity (very important anti-cancer function)
6. Enhanced prostaglandin formation
7. Enhanced nitric oxide production by phagocytes
Why is vitamin C the key to powerful immunity?
Red blood cells have roughly the same concentration of vitamin C as the surrounding plasma. Heart cells and kidney cells, which are very metabolically active cells, have about 13-fold more vitamin C than the plasma, an impressive concentration difference. This is certainly consistent with the continual need for electrons in such active cells.
Phagocytic white blood cells (granulocytes) have 25-fold more vitamin C than the plasma. Since these cells need an abundance of energy to consume and digest pathogens and cellular "debris," this concentration of vitamin C makes a lot of sense as well.
The king of the vitamin C concentrators, however, is the circulating monocyte, which becomes known as a macrophage, another cell with phagocytic functions, when it settles into the tissues. This cell has more than an 80-fold increased concentration of vitamin C inside it relative to the plasma. Few, if any, other examples of a circulating nutrient/vitamin being so selectively concentrated in a given cell type exist.
How vitamin C acts as a 'lifesaver'
Whenever inflammation develops, oxidative stress is increased, and vitamin C stores of the inflamed areas are acutely depleted to absent. The first cells that the immune system mobilizes to areas of acute inflammation are the monocytes.
As a hypothetical possibility, then, it would appear that this early, initial function of the immune system is to compensate for the inflamed area depleted of vitamin C with a vitamin C 'delivery system': the monocyte. This concept also meshes quite well with the fact that many other immune cells have significantly increased concentrations of vitamin C as well.
Always include vitamin C in whatever "wellness program" you choose to follow.
There are many things you can do and/or consume to help you achieve the health and wellness you seek. However, you should never be completely comfortable that your health program cannot be improved upon.
Donation of electrons at the molecular level, which is the ultimate positive impact of any therapeutic protocol, is the antioxidant effect. You always want more electron donation and less electron depletion (oxidation). Vitamin C, while not the only good antioxidant you can supplement, performs this electron donation/flow better than anything else available, and it still remains very affordable, in spite of repeated attempts to make it more expensive and market it as a "vitamin C complex" or "natural" vitamin C.
Vitamin C is truly 'designed by nature' – as most animals synthesize this essential nutrient as needed. Humans, unfortunately, lost this ability, but we still need to cope as best we can for our daily antioxidant needs.
