Time release
Time release. Your body cannot process a large dose of vitamin C all at once.. Vitamin C helps your body fight diseases. By spreading the vitamin Release over a full day, Ester C insures you are always protected.

Ester C BUT ~ Why is this product so expensive now??
This product looks like it’s made in the USA, so it’s perfect ~ EXCEPT needing it for medical reasons, like most of us is horrible to have to pay double the price!! ~ I get it, we are all fed up with high prices and on a fixed income it’s worse! I think Amazon could be a bit kinder on Supplements. ~ ~ Okay, this is the best Vit C, easy to swallow, doesn’t bother stomach. I’ve been buying this on Amazon for years, BUT, ”the Price” was always $6.97” Not sure I want to shop here for this double price, so very disappointing! ~ The last time I paid $6.97 was Jan/2024 and I stocked up because this happened once before, double cost to us. So, check in folks, hope it comes down to a decent price, stock up!!

Best Vitamin C Supplement For Sensitive Stomachs
If you have a sesitive stomach and can’t tolerate regular vitamin C, then this is for you. I have a very sensitive stomach and can’t drink orange or any citrus juice without terrible heartburn. Everyone needs some form of vitamin C for immunity and collagen production, so I take one of these daily, and increase to two a day during cold and flu season.
