Understanding Epicatechin and its Importance
Epicatechin is a plant-based flavonoid found in cocoa that acts as a powerful antioxidant. Research has linked epicatechin to several health benefits, including improved cardiovascular function, enhanced nitric oxide production for better blood flow, and potential anabolic properties related to muscle growth. For those seeking to increase their intake, not all dark chocolate is created equal, with processing having a profound impact on flavanol levels.
The Impact of Cocoa Processing
How cocoa is processed from bean to bar is the single most important factor determining its final epicatechin content.
- Fermentation: After harvesting, cocoa beans are fermented, a process that develops flavor but also causes a significant decrease in epicatechin levels. The duration and method of fermentation affect how much of the compound is lost.
- Roasting: The high heat of roasting further degrades epicatechin. Many commercial manufacturers use high roasting temperatures to ensure a consistent flavor profile, often at the expense of nutritional value. Opting for chocolates made with low-temperature roasted beans can preserve more flavanols.
- Dutch-Processing (Alkalization): This process involves treating cocoa with an alkali solution to reduce bitterness and create a smoother, darker product. However, it can destroy up to 60% of the flavanol content. If maximizing epicatechin is the goal, avoid any product that lists "processed with alkali" or is simply labeled "Dutch-processed".
Best Options: High-Flavanol Cocoa and Chocolate
For the highest concentration of epicatechin, unprocessed cocoa powder is often superior to a dark chocolate bar. However, high-quality chocolate bars can still be an excellent source.
Raw Cacao vs. Dark Chocolate
- Raw Cacao Powder: The raw, non-roasted version of cocoa offers the highest concentration of epicatechin by weight. It is ideal for smoothies, baking, or drinks, providing a potent dose without added sugar.
- Dark Chocolate Bars: When choosing a bar, look for the highest cacao percentage you can tolerate (70% or more). While a higher percentage doesn't guarantee higher epicatechin, it is a strong indicator of less sugar and more cocoa solids. A short, clean ingredient list with cocoa as the first ingredient is a good sign of quality.
Comparison: Selecting Your Epicatechin Source
Choosing between different cocoa products depends on your goals and taste preferences. This table outlines the key differences to help you decide.
| Product Type | Cacao Percentage | Epicatechin Level | Processing Notes | Flavor Profile | 
|---|---|---|---|---|
| Non-Alkalized Cocoa Powder | 100% Cacao | Highest | Not roasted or minimally processed with no alkali. | Intense, naturally bitter cocoa flavor. | 
| High-Quality Dark Chocolate | 70% to 85% | Moderate to High | Low-temperature roasting, minimal processing. | Complex, rich, and can have fruity or earthy notes. | 
| Commercial Dark Chocolate | 70% or less | Low to Moderate | Often Dutch-processed and highly roasted. | Sweeter and less complex due to processing. | 
| Milk Chocolate | Very Low | Minimal | High sugar, milk content, and heavy processing destroy most flavanols. | Sweet, creamy, and contains negligible epicatechin. | 
Best Brands and What to Look For
To ensure you are getting a quality product, consider these specific examples and tips.
- Godiva Chocolatier 85% cacao: A 2014 study found this brand's 85% bar to have a high epicatechin level (31.68 mg/40g serving) among those tested, although prices are higher.
- Lindt Excellence 70% Cacao: While an older study found its 70% bar had more epicatechin than its 85% bar, this highlights that percentage isn't the only factor; processing details matter. Lindt confirmed its 70% was not alkalized.
- High-Flavanol Cocoa Powders: Brands like FlavaMix and CocoaVia are specifically formulated to preserve a high flavanol content. These are often sold as dietary supplements or health-focused products.
- Organic and Raw Cacao Powders: Brands such as Navitas Organics, Terrasoul Superfoods, and SelvaBio offer minimally processed, often single-origin, cacao powder that can be a high-epicatechin source.
When buying, always read the label to check for "processed with alkali" or other signs of heavy processing. Look for products with a high percentage of cacao and few, simple ingredients to maximize your chances of getting a high-flavanol product.
Conclusion: Making the Right Choice
For those seeking the highest epicatechin content, raw or minimally processed cocoa powder is the superior option, free from the caloric load and processing effects of chocolate bars. However, if a chocolate bar is your preference, look for varieties with a high cacao percentage (70%+) from transparent brands that avoid Dutch-processing. Ultimately, the best dark chocolate for epicatechin is one with a high cacao content and a clean ingredient list, minimally processed to preserve the natural flavanols. Remember to consume chocolate in moderation due to its calorie content, balancing its benefits with a healthy, active lifestyle.

Frequently Asked Questions
Does a higher cacao percentage always mean more epicatechin?
No, not necessarily. While a higher percentage indicates more cocoa solids, the processing method (especially Dutch-processing) is the most critical factor affecting the final epicatechin content.
What is Dutch-processing and why should I avoid it for epicatechin?
Dutch-processing, or alkalization, involves washing cocoa beans in an alkaline solution to reduce acidity and bitterness. This process can strip cocoa of up to 60% of its flavanol content, including epicatechin, so it should be avoided if you want maximum health benefits.
What should I look for on the ingredient list to ensure high epicatechin?
Look for a short and simple ingredient list. The first ingredient should be cocoa or chocolate liquor. You should avoid any product that lists "processed with alkali" or high amounts of sugar as the first ingredient.
Are all types of cocoa powder high in epicatechin?
No. While unprocessed cocoa powder is the highest source, many common cocoa powders on store shelves are Dutch-processed. Always check the label to ensure it is natural or non-alkalized.
How does raw cacao differ from cocoa powder in terms of epicatechin?
Raw cacao powder is made from unroasted, cold-pressed cocoa beans, which helps preserve a higher concentration of heat-sensitive epicatechin compared to standard cocoa powder, which is roasted.
Can I get enough epicatechin from dark chocolate alone?
While possible, studies suggest you would need to consume a large amount of even the best dark chocolate to get therapeutic doses, which would also involve significant caloric intake. Many enthusiasts turn to high-flavanol cocoa powder or supplements for consistent dosing.
Do the cocoa beans' country of origin affect epicatechin levels?
Yes, the origin can impact the epicatechin content of the raw beans. Studies have shown variations in flavanol content based on geographical location. However, processing variables often have a larger impact on the final product.
