Capsules not chewable. I take 4 capsules in the morning on an empty stomach and I\'ve had no stomach probs from them. As Vit C can cause stomach probs, this is great. The chewable Vit C I tried in another brand made my mouth react with mouth ulcers. But as you swallow these thats not any issue. I\'ve been taking for just ova a month. I hav a really touchy stomach, IBS, lactose intolerant, sucrose, gluten, wheat and diary intolerances. And these hav caused no problems.
