Supplementation with 500 mg/day of water-soluble cinnamon extract for 12 weeks leads to a small but statistically significant increase in lean mass and a decrease in body fat percentage in pre-diabetic adults.

In addition to lowering blood sugar, this specific cinnamon extract may help slightly improve body composition (more lean mass, less fat) in pre-diabetic individuals over 12 weeks. This effect is small and should be viewed as a potential benefit alongside blood sugar management, not a primary weight loss strategy.
