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~

Sustained Release Vit. C

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.

I take this product with fish oil because I believe it to be fat soluble. Never experience stomach discomfort. Continue to reorder regularly.
