Sustained Release Vit. C
Posted by PeterPanos on Jan 27, 2016
Clean high quality sustained release vitamin C I've been looking for ages! I take one twice daily for continuous 24h coverage and it really helped me to boost my immune system. I will definitely buy again.
Totally mind blowing

Im a big fan of supplements, and do magnesium, zinc, coq10, k2 and omega 3 daily. Before i started with this i did doctors best C vitamin, but this sustained release version is mind blowing out of all supplements i take daily. It basically feels like im on a concentration mind-clarity buzz all day. Alot of studys shows that in a stressful enviroment the body will use up its storage of c-vitamin to try prevent stress in body. This supplements provides exactly what the body look for.
Works great, tastes perfectly acceptable

Nice size to swallow with some water. Works great to boost immunity, I recover from colds & flu quickly with combination of this & zinc 15mg. No negative effects on stomach whatsoever.

vc产品很多，doctor best家自己就有几种，选来选去还是买了这款，因为它能持续作用，且吸收好。据说比大热的ester c还有效果。坚持吃看看吧~
