Benefits
Cardiovascular support
A Cochrane review pooled 35 randomized trials (1,804 participants) and found that cocoa flavanol products lowered systolic and diastolic blood pressure by about 1.76 mmHg each. The authors rate this as moderate-quality evidence for a small, roughly 2 mmHg effect in mainly healthy adults in the short term. The trials tested cocoa products in general, not CocoaGanic.
Polyphenol activity in laboratory tests
Cocoa polyphenols neutralize reactive molecules in laboratory tests, but test-tube activity does not show what happens in the body. No human study has tested CocoaGanic itself.
Oxidative stress markers in trials of cocoa in general
These trials tested cocoa in general, not CocoaGanic. A pooled analysis of 33 controlled trials in 1,379 adults found that cocoa or dark chocolate lowered malondialdehyde, a marker of fat oxidation, but had no significant effect on most other oxidative stress and inflammation markers. In a 4-week double-blind trial in 50 overweight dieting adults, cocoa extract with 645 mg polyphenols daily lowered oxidized LDL more than control meals.
Mechanism of action
Flavanol nitric-oxide support
Cocoa flavanols are thought to increase nitric-oxide signaling in blood vessels, which is the usual proposed explanation for the small blood pressure change seen in cocoa trials. The Cochrane review did not measure nitric oxide, but a pooled analysis of cocoa and dark chocolate trials found higher nitric oxide levels.
Antioxidant action
Cocoa polyphenols scavenge free radicals in laboratory tests. In people, trials of cocoa in general found lower levels of some markers of fat oxidation, but no study cited here tested CocoaGanic itself.
Clinical trials
Cochrane systematic review and meta-analysis of 35 randomized trials (40 comparisons) on the effect of cocoa products on blood pressure. CocoaGanic was not one of the products tested. (Ried et al. 2017, Cochrane Database of Systematic Reviews)
1,804 adults, mainly healthy, pooled from 35 randomized trials; flavanol doses ranged from 30 to 1,218 mg per day (average about 670 mg), and the trials were short.
Cocoa flavanols produced a small but statistically significant reduction in blood pressure: about 1.76 mmHg systolic and 1.76 mmHg diastolic. The authors rate this as moderate-quality evidence for a roughly 2 mmHg effect in mainly healthy adults in the short term. Stomach complaints and nausea were reported by about 1% of participants on cocoa and 0.4% on control.
