Potential benefits of raisin water

Although no studies have specifically examined raisin water, it may increase your intake of iron and antioxidants. That’s because it’s made from raisins, which are dried grapes.

Keep in mind that research on raisin water itself is still necessary.

Raisin water is a good source of antioxidants

Raisins are rich in antioxidants, which are beneficial compounds that protect your cells against harmful compounds known as free radicals.

Raisins are exceptionally high in ferulic acid, rutin, quercetin, and trans-caftaric acid.

Antioxidants play a crucial role in health and may safeguard against chronic conditions like cancer, type 2 diabetes, and Alzheimer’s disease.

Notably, a study of 15 people showed that antioxidant levels in the blood increased significantly about 1 hour after they ate raisins.

In a study that gave aging rats 0.2 ounces (6 grams) of raisins daily, they experienced increased blood antioxidant levels and improved brain function.

Still, further research is needed.

Raisin water may safeguard against iron deficiency

Raisins contain a fair amount of iron, with just 1 ounce (28 grams) supplying nearly 3% of the daily value.

This mineral is involved in oxygen transport and red blood cell production. Not getting enough iron in your diet may lead to iron deficiency anemia, a condition whose symptoms include fatigue, shortness of breath, pale skin, and weakness.

Nonetheless, studies are needed to confirm the exact nutrient profile of raisin water.

Summary: Although raisin water has yet to be studied, it may boost your iron intake and antioxidants.


Although raisin water is considered safe for most adults, some people may need to limit their intake.

Summary: In rare cases, raisin water may cause an allergic reaction. It may also be relatively high in calories, carbs, and natural sugars. Opting for fresh grapes would be more beneficial for your health.

How to make raisin water

Raisin water is easy to make at home using just two simple ingredients.

Bring 2 cups (475 mL) of water to a boil in a saucepan or pot to get started. Next, remove it from the heat and add 1 cup (145 grams) of raisins to the water.

Let the raisins soak overnight, or for at least 8 hours, before straining out the fruit using a colander or sieve.

It’s typically recommended to heat raisin water on the stovetop or in the microwave before drinking it.

Although you can enjoy raisin water anytime, proponents suggest drinking it before breakfast to maximize its potential benefits. However, no research indicates that it’s more beneficial in the morning.

Summary: You can make raisin water by adding raisins to boiling water, soaking them overnight, and straining the fruit. Although you can drink raisin water anytime, advocates recommend enjoying it first thing in the morning.
