Obesity / Weight Management: Green Tea, Supplements & What Actually Works

Weight management is one of the most aggressively marketed supplement categories, which makes it one of the places where evidence and product safety matter most.

Quick answer

NCCIH states that most supplements marketed for rapid weight loss have not been proven safe or effective. Green tea supplements have not been shown to produce meaningful weight loss.

Green tea

Green tea as a beverage is generally considered safe for adults in moderate amounts, but concentrated green tea extracts can cause side effects and have been linked to rare liver injury.

Evidence strength

Norene’s Farmacy rating for supplements marketed as weight-loss products: INSUFFICIENT EVIDENCE FOR MEANINGFUL LONG-TERM WEIGHT LOSS, WITH IMPORTANT SAFETY CONCERNS FOR SOME PRODUCTS.

What we do not claim

We do not claim that teas, gummies, herbs, powders, or supplements cause rapid or guaranteed weight loss, melt fat, or replace nutrition, movement, medical care, or evidence-based obesity treatment.
