How to Take Vitamin C at Night

Ascorbic acid, or vitamin C, helps heal wounds, repairs tissue and produces protein to make skin, tendons and blood vessels. Deficiencies in vitamin C may present in the form of gingivitis, dry skin, easy bruising and the inability to fight off infections. Since your body does not produce its own vitamin C -- nor does it store it -- the University of Maryland Medical Center suggests taking 250 to 500 mg of vitamin C two times a day. Check with your doctor before taking any dose of vitamin C and before giving vitamin C to your child.

Step 1

Divide your dosage of daily vitamin C supplement into two to three measures. This allows you to take a smaller dose with each meal.

Step 2

Take your last dose with your evening meal, so you do not take vitamin C on an empty stomach. Taking vitamin C without a meal may leave your stomach upset.

Step 3

Eat fruits high in vitamin C as a late-night snack if you do not take supplements. Strawberries, cantaloupes, oranges and papaya provide a range of 130 to 300 mg of vitamin C per serving.
