Can you take too much vitamin C?

Short answer: Vitamin C is water-soluble, so the body tends to pass what it doesn't use, but very large amounts can cause stomach upset or loose stools for some people. Splitting it across the day or taking it with food may feel gentler. For the right amount for you, ask your doctor or pharmacist.

Why more isn't always better

Because vitamin C is water-soluble, the body generally excretes the excess rather than storing it. Still, taking a lot at once can cause digestive discomfort for some people, such as an upset stomach.

Taking it with food, or splitting it into smaller amounts across the day, often feels easier on the stomach.

A steady, sensible routine

Rather than large occasional amounts, a modest daily habit is easier to sustain and to track. Pillog lets you schedule it, check it off from the notification, and see your month as a card, all kept on your phone with no account and no ads.

How much is right depends on your diet and situation, so let your doctor or pharmacist guide the amount.
