By the way, doctor: What's the right amount of vitamin C for me?
Q. I'm 79 years old and have been taking 3,000 mg of vitamin C a day for years. I'm now uneasy about taking this amount and plan to cut back to 1,000 mg daily. Is this the right vitamin c dose? Will my body be startled by the abrupt change?
A. Cutting back on daily vitamin C is a wise decision. You've been taking much more vitamin C than you need.
