Sustained Release Vitamin C

60 Tablets DRB-00191

Slowly But Surely. 

You may take vitamin C, but not like this. Thanks to PureWay-C®, our sustained release option has proven cell retention for a longer period of time compared to other forms of vitamin C.* It is also more efficiently absorbed during the sustained release period.* Think about it as a slow burn: it gradually releases into your system throughout the day, not all at once. PureWay-C® has a proven absorption rate that is over 200% higher than standard vitamin C and has the potential to more potently enhance immune system activity when compared to other forms of vitamin C.* In other words, it packs a punch.

Excellent Vitamin C. I read a lot of good reviews about it and decided to try it myself. It has high bioavailability and strengthens the immune system well!
