4. Consists of Nutrients

Coffee consists of nutrients. A single cup of coffee consists of :
• Riboflavin (vitamin B2): 11% of the Reference Daily Intake (RDI).
• Pantothenic acid (vitamin B5): 6% of the RDI.
• Manganese and potassium: 3% of the RDI.
• Magnesium and niacin (vitamin B3): 2% of the RDI.

However, these amounts are smaller but most people enjoy many cups a day to add these amounts up.
