Other vitamin C supplements I’ve tried have been larger and not coated (especially if they’re not time-released) and can be scratchy and uncomfortable to swallow. I take 2 a day and there’s been no stomach issues. As an elementary school teacher I’m exposed to germs constantly so I try to keep vitamin C as part of my supplement routine. Will continue to purchase this brand.
