What customers say

Customers highly appreciate the Source Naturals C-1000 for its good quality, affordability, and effective time-release feature. Many users report increased energy levels and improved immune systems with daily use. The product is praised for being easy to digest, having a neutral smell, and being convenient to take. Some customers mention using it to reduce inflammation and stress, while others note its benefits in preventing colds and maintaining overall health. The caplets are described as pleasant-tasting and easy to swallow or dissolve in the mouth. Packaging is also well-received. However, a few customers wish for larger tablet sizes to be stocked by iHerb.

Corn free!

Verified purchase

I'm thrilled to finally find a good quality corn free vitamin C! They're on the large side, but have a pleasant taste and they go down reasonably easily. I take one daily, and double that when sick. I've been pleased with these. It took forever to find something without corn in the ingredients, which I'm allergic to.
