ウルトラ ビタミンC

Switched to these after my regular C tablets wore off by lunchtime, and the slow release actually makes a difference — steady energy instead of that midday crash. Two tablets with breakfast and I'm set until evening.

I've been taking these for about two months now and the slow release formula really does seem to keep me steady instead of that up-and-down feeling I got from regular C tablets. The tablets are easy to swallow and I haven't had a single cold this winter.
