Fast Lean Pro: The Truth Behind the Claims

Fast Lean Pro is a dietary supplement that claims to support weight loss and liver health. It is made with a blend of natural ingredients, including milk thistle extract, green tea extract, berberine, choline, and betaine.


  • Milk thistle extract: Milk thistle extract is a known antioxidant that helps to protect the liver from damage. It has also been shown to have anti-inflammatory and cholesterol-lowering effects.
  • Green tea extract: Green tea extract is a rich source of antioxidants, including catechins. Catechins have been shown to boost metabolism and promote fat burning.
  • Berberine: Berberine is a plant alkaloid that has been shown to have a number of health benefits, including improved blood sugar control, reduced cholesterol levels, and weight loss.
  • Choline: Choline is an essential nutrient that plays a role in liver function and fat metabolism.
  • Betaine: Betaine is another essential nutrient that helps to support liver function.


There is limited scientific evidence to support the claims made about Fast Lean Pro. While some of the ingredients in Fast Lean Pro have been shown to have beneficial effects on weight loss and liver health, more research is needed to confirm the effectiveness of Fast Lean Pro itself.

One small study found that people who took Fast Lean Pro for 12 weeks lost more weight and had greater improvements in liver function than those who took a placebo. However, more research is needed to confirm these findings.
