"This is easily the best value on sustained release C. In general the NSI product lags a few of the other brands. But this particular one is spot on. About the only complaint I have is that it only comes in 1000mg. I would prefer to have a 500mg. But other then that, the product works as advertised and the cost is low in comparison to the other offerings."
