These human studies looked at specific ingredients. Read what researchers measured and how the studies were designed.
ONE STUDY, UP CLOSE24 hours
A metabolic snapshot
In a small study of 10 men, a specific green tea extract containing catechins and caffeine increased measured 24-hour energy expenditure versus placebo. A one-day result does not establish long-term weight loss.

African mango extract
In 102 adults, a 10-week trial reported changes in weight and metabolic markers with a particular African mango seed extract, not the ThermoX formula.
IGOB131, a novel seed extract of the West African plant Irvingia gabonensis, significantly reduces body weight and improves metabolic parameters in overweight humans in a randomized double-blind placebo controlled investigation.
Green tea alongside exercise
In a 12-week exercise program, a catechin-rich drink reduced abdominal fat measures more than control; the weight difference was not significant.
Green tea catechin consumption enhances exercise-induced abdominal fat loss in overweight and obese adults.
When green tea results differ
Another 12-week placebo-controlled trial found no significant difference in weight, BMI or waist reduction with its green tea extract.
Effect of green tea extract on obese women: a randomized, double-blind, placebo-controlled clinical trial.
Raspberry ketones in a blend
A trial paired a different multi-ingredient supplement with diet and exercise. Its results cannot be credited to raspberry ketones alone.
Eight weeks of supplementation with a multi-ingredient weight loss product enhances body composition, reduces hip and waist girth, and increases energy levels in overweight men and women.
What a vinegar trial measured
A 12-week trial found changes in weight and fat measures with daily vinegar drinks. It did not test apple cider vinegar powder or ThermoX.
Vinegar intake reduces body weight, body fat mass, and serum triglyceride levels in obese Japanese subjects.
These studies tested specific ingredients, extracts and doses; they did not evaluate the finished Astral product. Individual results may vary.
