Introduction

Dark chocolate with 70% or higher cocoa content is far more than a treat—it is a concentrated source of powerful plant compounds that support cardiovascular health, brain function, and emotional well-being.

Unlike milk chocolate, high-cocoa dark chocolate contains minimal sugar and a high density of flavonoids, minerals, and mood-supporting compounds, making it one of the most researched functional foods.

What Is Dark Chocolate (70%+)?

Dark chocolate is produced from cocoa solids and cocoa butter with little or no milk added. A cocoa percentage of 70% or higher indicates a greater proportion of cocoa solids and significantly less sugar.

The higher the cocoa percentage, the richer the chocolate is in antioxidants and minerals—along with a more intense, slightly bitter flavor.

• Small amounts of caffeine

Key Health Benefits

• Supports heart and blood vessel health
• Improves brain blood flow and cognitive performance
• Enhances mood and stress resilience

Cocoa polyphenols interact positively with gut bacteria.

• Feeds beneficial gut microbes
• May reduce harmful bacterial growth
• Supports gut barrier integrity
• Improves polyphenol bioavailability through fermentation
