2 1 jinvita and shancun are both medicines for supplementing multivitamins and minerals, with similar effects, but 2 1 jinvita is more affordable and has more comprehensive trace elements, so it should be the first choice for supplementing multivitamins. However, the content of vitamin C in both of them is not very high. If you want to supplement vitamin C, enhance resistance, speed up disease recovery and beauty, it is recommended that Yangshengtang take vitamin C and 265438. If you still want beauty and anti-aging, add a vitamin E, which will have a good effect after long-term use! I wish you health and beauty!
