Time-released, easy to swallow
Love these because they’re extended release and easy to swallow. 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.

Great prolonged release vitamin C tablets
Really happy with this Vitamin C! The prolonged release feels like it keeps my immune system supported throughout the day. Great value for the money, and I definitely feel more energized and less run-down since I started taking it. Also great for skin and overall antioxidant support.

Easy to take and no upset stomach
I take one each evening to insure I’m getting my Vitamin C. They are easy to swallow with no taste I can discern. I haven’t had any stomach upset or other issues with this product. I cannot attest to any health benefits this product offers but if you need to supplement your Vitamin C intake, this seems to be the way to go.

Great value for the price!
This vitamin C supplement was sent to me on time and in perfect condition, complete and sealed tablets. I like that they are 1000 MG per unit, so it is easier for me to have my daily supply complete and its antioxidant properties, it also prevents forgetting when taking it, the commitments are compact, easy to swallow, without notable odor or taste, the price is very affordable .
