This product seems to be more expensive than most Vit C varieties I've seen in stores but it's a 90-day supply when you take 1 capsule per day as indicated on the bottle. Each capsule has 1000mg of Vitamin C (as ascorbic acid) and is Gluten-free, non-GMO and hypoallergenic. I was a little worried about taking these capsules because they were so large (see pic), but they were very easy to swallow with water. The company states that their products are free from wheat, eggs, tree nuts & peanuts, gluten, artificial colors, fillers, preservatives and more. I like to know the manufacturing process of these types of products and this company seems to apply a more stringent and conscientious philosophy. The only downside is the cost but I'm willing to pay it to have these product production processes.
