Maqui Berry & Blood Sugar: What Human Research Shows
Fact checked against the cited sources. Commercial details checked September 8, 2026.
Maqui berry (Aristotelia chilensis) is a dark-purple fruit rich in anthocyanins. GlucoBerry uses a standardized maqui berry extract, making the ingredient relevant to the product's core marketing story.
The human trial most relevant to GlucoBerry
A 2014 randomized, double-blind, placebo-controlled crossover study tested a standardized maqui berry extract in ten people with moderate glucose intolerance. The researchers reported a lower post-meal glucose and insulin response after the extract compared with placebo.
Why ten participants is not enough for certainty
Small crossover studies can detect signals, but estimates are less stable and less generalizable than results from large, repeated randomized trials across diverse populations. The study is hypothesis-supporting rather than definitive.
How this connects to GlucoBerry
The current GlucoBerry label identifies 180 mg of standardized maqui berry extract. To understand the rest of the formula, continue to GlucoBerry ingredients or our full review.
