Could a less strict diet improve life for adults with rare glycogen storage disease?
NCT ID NCT06852612
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether adults with glycogen storage disease type I (GSDI) can safely include more fructose and galactose in their diet. Currently, patients must avoid these sugars, which limits food choices. Researchers will give 20 adults either fructose alone or fructose plus galactose and measure changes in blood lactate, triglycerides, and uric acid. The goal is to see if relaxed dietary restrictions could improve quality of life without harming metabolic control.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Fructose and galactose (dietary supplements)
What this could lead to
If successful, this could show that adults with GSDI can safely include more fruits and dairy in their diet, improving food choices and quality of life.
What could go wrong
This is a small, early-phase study with only 20 participants, so results may not apply to everyone. The dietary changes could cause metabolic imbalances in some patients.
