The Claim

Oral hydroxycitrate supplementation at 500 mg with a high-carbohydrate meal after endurance exercise reduces postprandial insulin response by approximately 39% in healthy young men without altering blood glucose levels.

In plain English

Taking 500 mg of hydroxycitrate with a high-carbohydrate meal after endurance exercise lowers the insulin response by about 39% in healthy young men without changing blood glucose levels.

See the scientific wording

Oral hydroxycitrate supplementation (500 mg) with a high-carbohydrate meal after endurance exercise reduces postprandial insulin response by approximately 39% in healthy young men without altering blood glucose levels, indicating improved insulin sensitivity.

Why this might work

After exercise and a carb-rich meal, hydroxycitrate blocks a key step in sugar breakdown, forcing the body to store more sugar as glycogen in muscles instead of burning it. At the same time, the body switches to burning fat for energy, which reduces the need for sugar. With more sugar stored and less needed for fuel, the pancreas releases less insulin to manage blood sugar levels.

What the research says

  1. Study: Oral hydroxycitrate supplementation enhances glycogen synthesis in exercised human skeletal muscle

    After working out and eating carbs, taking hydroxycitrate made the body need less insulin to handle the same amount of sugar, meaning it became better at using insulin efficiently.
