Potential Health Benefits of Lemon Juice

While more research is needed to confirm some of these benefits in humans, lemon juice has been associated with several potential health advantages:

Potential Benefits

• Good Source of Vitamin C: Vitamin C is a powerful antioxidant that supports the immune system, protects cells from damage, and is important for collagen production (skin health).
• May Aid Digestion: Some people find that drinking lemon water helps with digestion and reduces bloating. The citric acid in lemon juice may stimulate gastric acid production.
• May Help with Hydration: Adding lemon juice to water can make it more palatable, encouraging increased fluid intake.
• May Help Prevent Kidney Stones: The citric acid in lemon juice may help prevent the formation of calcium kidney stones by increasing urine citrate levels and reducing urine acidity.
• May Support Heart Health: The vitamin C and flavonoids in lemon juice may have antioxidant and anti-inflammatory effects that could benefit heart health. However, more research is needed.
• May Have Antimicrobial Properties: Lemon juice has some antibacterial and antiviral properties.
• May Help with Iron Absorption: Vitamin C enhances the absorption of non-heme iron (the type of iron found in plant-based foods).
• May Promote Skin Health: Vitamin C is important for collagen production, and the antioxidants in lemon juice may help protect the skin from damage.

Important Note: Many of the health benefits attributed to lemon juice are due to its vitamin C content and other beneficial compounds. Drinking large quantities of lemon juice is not necessary and may have negative effects (see “Potential Risks and Side Effects”).
