俺的VC简史

俺的VC简史

博客

小时候,每逢冬春缺新鲜蔬菜水果时,妈妈会从医院开些魚肝油、维生素C(那年头也叫“抗坏血酸”)之类。更多的时候从药店买,当时很便宜,就是老缺货。

还记得维生素C的小圆柱型棕色瓶,里面装的绿豆大黄色小圆粒。每天每人给三五粒,大人们喝口水咽下去了。俺特喜欢那味道,每次一粒在嘴里含着,先甜后酸,最后剩个小硬心,嚼起来嘎嘣响。

那时候的维生素C,都是从橙子里提纯的,味道特好,闻着也舒服。

有一次实在忍不住,一口气吃了小半瓶。接下来肚子疼,串稀,闹腾一夜。

打那起,不再贪多了。

文革起,爸、妈被改造,特权没了。每人每月发八块钱生活费,除了饭伙,连煤都买不起了,别说啥维生素了。

以后长大了,再也没用。

后来有了孩子,再喂维生素。

不过,魚肝油没有了,叫啥维生素D。抗坏血酸也改称维生素C,不用橙子了,都是人工半合成的。

更便宜了,也没那些诱人的味道了。每次费尽心思哄孩子吃。

 

再次服用维生素C,己经是2015年了。系统化疗后特疲惫,加服vc有利于体能恢复。当时用的是500mg片剂,早晚一粒随饭走。

 

这次新冠疫情开始后,买了些片剂备着,后来又买了一桶粉剂,按磅算,特便宜。专门预备一个小塑料勺,一满勺为四克。有点风吹着凉,挖一勺,冲半杯水,趁热喝。效果不错,就是胃里不好受。我还能挺,家里那位不行。

于是,查找VC的代用品、或肠溶胶囊。找到了这种脂质体Vc。

这东东最大的好处是没有胃肠道刺激作用,而且缓释,可以长时间维持稳定血液浓度,无需几小时服一次。我们在有感冒症状时,立即服四粒,差不多当天就好。没好利索,第二天再来四粒。

 

打去年起,又发现新的针对新冠开发的复方剂型。据称能提供24小时免疫防御。

除了脂化VC外,加了锌、VD、VA等多种据说能抗新冠的成分。小贵,仍能承受。

我们每次外出购物、上班、看病时,早上服一粒。

有流涕、鼻塞、咽喉不适时,“吞”四粒。千万別四粒一起放嘴里咽,一粒咽下去,再来一粒。

效果不错,就是粒大,嗓子眼儿小的可能被噎住。

 

随着时代,VC也在不断翻花样,应用越来越多。

 

1. 中国VC史

https://www.sohu.com/a/225144824_100030976

维生素C最早是从动植物中提炼出来的,如橙子。后来人们可能发现太费橙子了,于是发明出发酵制造法来生产维C,通过微生物或酶将有机化合物分解成其它化合物的方法”

…………

“1980年,中国无法忍受长期被海外巨头把持维C产业的局面,成功改进了维C的生产工艺,当时中科院微生物所尹光琳发明了“两段发酵法”,大大降低了维C生产的复杂程度和生产环境要求,更重要的是极大地降低了维C的生产成本,这大大提升了维生素C的产量。”

…………

到今天,全球超过90%的维C由四家中国药厂——东北制药、华北制药、石药集团和江山制药生产,中国具有维C绝对的产量权和定价权”

 

2. 粉沫状脂质体VC

https://coremedscience.com/blogs/wellness/how-to-pick-the-best-liposomal-vitamin-c

There are two basic types of liposomal supplements that have to do with "liposome" formation. The first is an already formed liposome vitamin C and, while the other is a pro-liposome. A pro-liposome is chemically bound vitamin C and contains phospholipids in a manner which will result in a liposome formation in the presence of water at body temperature.

The simplest way to tell if a product is a formed liposome is if the ingredients include water. If water is in the ingredients, you are likely dealing with formed liposomes. If not, you are looking at a pro-liposome. Make sure however that both contain phospholipids like phosphatidylcholine (derived from lecithin). 

A pro-liposome has the potential to become a liposome when exposed to water, forcing the phospholipids to immediately congregate by natural hydrophobic forces into a bi-layer as described above.

In the form of a pro-liposomal powder, the vitamin C is surrounded (conjugated) by a layer of phospholipids and other fats in a special technical process that can greatly vary in effectiveness. How well this proprietary process of binding the lipids to the vitamin C occurs is key, because if the lipids and the vitamin C are only mixed together (not bound), the formation of liposomes with vitamin C inside will be sporadic at best as the vitamin C can just disperse away separately from the lipids.

 

3. 脂化C

Safety and tolerance of ester-C compared with regular ascorbic acid

https://pubmed.ncbi.nlm.nih.gov/16644619/

https://return2.health/articles/3faces-vitaminc

https://pediaa.com/difference-between-vitamin-c-and-ester-c/

Ester C contains Calcium ascorbate as its the main chemical ingredient. Its IUPAC name is calcium (2R)-2-[(1S)-1,2-dihydroxyethyl]-4-hydroxy-5-oxo-2H-furan-3-olate. Its chemical formula is CaC12H14O12. It also contains vitamin C metabolites.

Ester C has three or four times greater bioavailability than regular natural vitamin C. But this fact is highly controversial. 

Ester C is a pH neutral product.
