Raw garlic kickstarts powerful detox mechanisms in your liver thanks to the phytochemical allicin. When garlic is smashed or chopped, it releases certain enzymes that produce allicin. This increases your liver's natural cleansing systems. This process helps decrease the amount of fat accumulating in your body, as well as oxidative stress.

Allicin Activation

  • Mechanism: Converts to active sulfur compounds
  • Effect: Boosts glutathione by 40%
  • Preparation: Crush and wait 10 minutes before consuming

Fat Reduction

  • Mechanism: Regulates fat metabolism genes
  • Effect: Lowers liver fat accumulation
  • Dose: 2-3 cloves daily

Anti-Inflammatory

  • Mechanism: Blocks NF-kB inflammatory pathway
  • Effect: Reduces liver enzyme markers
  • Synergy: Combines well with olive oil

Detox Enhancement

  • Mechanism: Activates phase II detox enzymes
  • Effect: Speeds toxin elimination
  • Tip: Consume with cruciferous vegetables

The sulfur compounds found in garlic promote the generation of glutathione - the master antioxidant produced by your liver. Glutathione neutralizes toxins in your body, including alcohol metabolites and environmental contaminants, increased levels of glutathione lead to improved liver cell protection against damage and an increased ability to regenerate.

Use garlic wisely to gain your maximum protection. Add raw, crushed garlic to salad dressings, dips, and other recipes for added flavor. Add it to cooked foods at the end of the cooking process. Cooked together with onion and olive oil, there is a synergistic effect. The liver protection capability comes from daily use.

For optimal strength, look for solid, plump bulbs with tight, taut skin. Avoid chopped or pre-minced products, as they quickly lose their allicin content. Store at room temperature, away from direct light. Each of these steps preserves garlic's bioactive constituents, providing optimal support to the liver with every serving.
