Can You Take Vitamin C at Night?

Yes, you can take vitamin C at night.

Vitamin C, also known as ascorbic acid, is like your body’s personal repair crew.

This vitamin is water-soluble, meaning your body absorbs what it needs and flushes out the rest. Unlike fat-soluble vitamins, it doesn’t require food or specific timing to work effectively.

However, some people may want to avoid taking it before bed:

  • If you have acid reflux or a sensitive stomach – Vitamin C, especially in high doses, can increase stomach acidity, and lead to mild heartburn or nausea.
  • If you take high doses (above 500 mg) – Larger amounts can cause digestive discomfort, including bloating or loose stools.
  • If you take certain medications – Vitamin C may interact with some drugs, such as blood thinners. If unsure, consult your doctor.

If you’ve ever experienced nausea, heartburn, or stomach upset from vitamin C, you may take it earlier in the day or with food to minimize discomfort.

Vitamin C and Sleep – Any Connection?

You might have heard that vitamin C gives an energy boost and now wonder if it disrupts sleep. But there’s no scientific evidence that vitamin C keeps you awake.

In fact, research suggests vitamin C may actually support better sleep. A study found that people who consumed more vitamin C had a lower risk of sleep disturbances, including insomnia and sleep apnea.

Vitamin C is a strong antioxidant, meaning it helps protect your cells from damage. This damage can stress the body and affect sleep. By reducing this stress, vitamin C may help your body recover better at night and support more restful sleep.

Additionally, research found that individuals with shorter sleep durations had lower intakes of vitamin C. This suggests a potential link between adequate vitamin C consumption and healthy sleep patterns.

While more research is needed, there’s no strong evidence that Vitamin C harms sleep.
