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

Posted by Reviewer1702027 on Jan 28, 2016

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.

Highly pleased.

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