## Questions & Answers

**Q: The tablets are huge and dry and get stuclk in your throat. Are these capsules or caplets and what is the difference, I want the smooth ones?**
A: These are capsules. The tablets say tablets and are a little less expensive but they are coarse horse pills as you mentioned. The capsules are still big but easier to handle imho.

**Q: Do these have any adjuvants?  Like stéarate etc.**
A: I do not know if Ester-C has adjuvants.  All I do know is that I've been taking this particular brand of Vitamin C for years because it keeps Vertigo at bay because of the bioflavonoids. I have literally taken this product when I had the beginnings of vertigo symptoms and they went away within a few hours!  It helps with drying out and balancing the middle ear.   Also, I have not gotten sick in many years and take this on a daily basis

**Q: Has this product been tested by USP?**
A: I had to look up USP - I don't know. There's nothing I see on the label. I'm pretty rigorous in researching products that I consider buying and this product passes muster with me.

**Q: Is 500 mg tablets smaller than ester-c vitamin c, 1,000 mg tablets?i need a smaller tablets so i need to decide which tablet is smaller.thnx**
A: Yes, I have the same issue with the extremely large 1000 mg tablets in this brand. I typically only take half of them. The capsules are smaller. I am rusty on my capsule sizes--  but they ar definitely smaller and much easier to swallow than the larger strength tablets. They are not the smallest size capsules. I think you will manage them.
