Good idea, CCS!
I've been shocked in recent years about the trend toward individual vitamin C supplements which are getting larger and larger. Years ago, I actually used to be able to get 100 mg tablets. Then those went away, and the smallest available was 250 mg. Now those appear to be gone (at least, I haven't been able to find any), and 500 mg tablets are currently the smallest I can find. That's an obvious indication of how confident the public is getting at taking supplementary vitamin C: when I first started taking them about 37 years ago, people were worried that it might be REALLY DANGEROUS to take much more than the RDA (about 30-60 mg)!
Until very recently, I'd been using 250 mg vitamin C tabs from HEB grocery stores. They were neatly scored down the middle, and I could easily snap them into two pieces, each half being 125 mg. I'd take one of those halves several times throughout the day. Then a few months ago, I noticed that they weren't selling the 250's anymore. All they have now are 500's, and they aren't scored. Now I'm forced to break the 500's into halves (which requires some effort), and then break the halves into quarters. I am NOT a happy camper because of that! :evil:
