The Nutrition Profile of Grapes
Grapes are low in calories but full of important vitamins, minerals, and other beneficial plant compounds. Some of the top nutrients found in grapes include:
- Vitamin C - One cup of grapes contains 27% of the recommended daily intake for vitamin C, an essential nutrient that acts as an antioxidant and supports immune health.
- Vitamin K - Grapes contain around 28% of the RDI for vitamin K per cup. This vitamin plays a key role in blood clotting and bone health.
- Potassium - With 191 mg per cup, grapes offer 5% of the RDI for potassium. This mineral is necessary for heart health, fluid balance, and muscle and nerve function.

Beyond vitamins and minerals, grapes are also rich in beneficial plant compounds like anthocyanins, resveratrol, quercetin, and catechins. These antioxidants give grapes their vivid colors and contribute to their therapeutic effects.
