The Potential Benefits of Cocoa Bean Extract
Cocoa bean extract has been gaining attention recently for its potential effects on age-related memory loss. Cocoa beans contain flavanols, a type of antioxidant that may help protect the brain against cognitive decline.
Cocoa Flavanols and Brain Health
Research has shown that cocoa flavanols have several beneficial effects that could combat memory loss. These include:
- Improving blood flow to the brain
- Reducing inflammation
- Protecting neurons from damage
By improving circulation and protecting brain cells, cocoa flavanols may be able to slow down age-related memory impairment and other effects of aging on cognitive function.
Studies on Cocoa Flavanols and Memory
Several studies have found promising results when testing cocoa bean extracts or flavanol supplements on memory in older adults. For example:
- In one study of 90 healthy older adults given a high or low flavanol drink for three months, those who consumed more flavanols showed improvements to blood flow in certain areas of the brain needed for memory tasks.
- Another study had 37 healthy older adults take a cocoa flavanol supplement for three months. At the end of the study, this group performed better on a memory test than the control group.
- Similar benefits for memory were found in other studies of older adults taking flavanol supplements for time periods ranging from a few weeks to three months.
While more research is still needed, these initial results suggest supplementing with cocoa flavanols could boost memory function.
Getting Flavanols from Cocoa Beans
Since the promising memory research has used flavanols extracted from cocoa beans, many people wonder about the best source. Here are some facts about getting flavanols from cocoa:
Cocoa Beans vs Cocoa Powder
Cocoa beans contain the highest concentration of flavanols because they are raw. When beans are processed into cocoa powder, it reduces levels of flavanols due to exposure to heat, oxygen, and alkalization. However, cocoa powder still contains flavanols.
Special processing methods can help retain more nutrients. So cocoa powder labeled as minimally processed, non-dutched, or natural may have higher flavanol content.
Cocoa Bean Extract Supplements
Cocoa bean extract supplements offer another convenient way to get flavanols. Look for products standardized to a certain percent of flavanols or cocoa flavanol content.
Since supplements are manufactured from cocoa bean extract, their flavanol content is generally much higher per serving compared to cocoa powder.
Dark Chocolates Flavanols
Dark chocolate contains cocoa flavanols as well, though in smaller amounts. The cocoa content and exact processing method determines quantities. Go for dark chocolate with at least 70 percent cocoa.
While chocolate makes getting flavanols tasty, supplements or powders are needed at higher doses for research-backed memory benefits.
Other Health Benefits of Cocoa Flavanols
In addition to effects on memory, cocoa flavanols offer other benefits:
Cardiovascular Health
Several studies link cocoa flavanols to heart health. Likely due to improved circulation, they may:
- Lower blood pressure
- Improve cholesterol and triglycerides
- Decrease risk factors for diabetes and heart disease
- Reduce blood clotting
More research confirms cardiovascular benefits than for memory currently, but both areas show promise.
Brain Blood Flow
Research shows cocoa flavanols boost blood flow to the brain, which oxygenates cells and clears away waste. Better circulation results in upgrades to certain cognitive skills.
Along with enhancing memory, increased brain blood flow could potentially slow dementia development and improve reaction times, focus, and mental clarity.
Antioxidant Effects
The flavanols in cocoa beans are powerful antioxidants. They help counter oxidative damage from everyday exposure to toxins, stress, and aging.
Through these antioxidant effects, cocoa flavanols may strengthen immune function, decrease inflammation, and protect cells from harmful free radicals.
Dosage Recommendations
Most studies showing memory or other health benefits use cocoa extract capsules with the following doses of flavanols:
- 500 to 800 mg per day
- 30 to 45 mg per kg of body weight
This equals around 900 to 1400 mg daily for a 150 pound person. Amounts used for cardiovascular benefits fall within the same range.
Check supplement labels for the cocoa flavanol content rather than just relying on the capsule dosage.
Possible Side Effects
Cocoa supplements are considered very safe. However, potential side effects can include:
- Upset stomach
- Bloating
- Gas
- Constipation
- Headaches
- Sleep difficulties
These effects are usually mild at the doses linked to health benefits. If any become bothersome, lower your intake.
The Bottom Line
Research suggests supplementing with cocoa bean extract could boost brain health. It may improve memory, cognition, and cardiovascular function for older adults.
While current studies show promise, more research is still needed. But given its safety and long historical use in chocolate, trying cocoa bean extract is worthwhile for those concerned about preserving memory with age.
Aim for evidence-backed doses of cocoa flavanols around 500 to 900 mg daily. Seek minimally processed cocoa powder or quality supplements to get beneficial concentrations of these antioxidant and anti-inflammatory compounds.
