Nutritional Profile of Lemon Peels
Lemon peels are rich in nutrients despite being consumed in small quantities. Every tablespoon (about 6 grams) of lemon peel contains:
- Calories: 3
- Dietary fiber: 1 gram
- Vitamin C: 9% of Daily Value (DV)
- Calcium: 7% of DV
- Potassium, magnesium, and small amounts of other vitamins
Lemon peel is also loaded with plant compounds such as d-limonene, bioflavonoids (like hesperidin and diosmin), and pectin, contributing to its unique benefits.
Key Health Benefits of Lemon Peels
1. Boosts Heart Health
Lemon peel’s high vitamin C content and bioflavonoids can support cardiovascular health by reducing blood cholesterol levels, lowering risk of stroke, and supporting healthy blood vessels. Pectin—a soluble fiber in lemon peel—helps further reduce cholesterol, while potassium supports healthy blood pressure.
2. Loaded with Antioxidants
Antioxidants such as vitamin C and d-limonene in lemon peels neutralize free radicals and fight oxidative stress, protecting cells from damage and slowing aging-related degeneration. These compounds help lower the risk of chronic diseases, including diabetes and cardiovascular conditions.
3. Strengthens Immunity
With abundant antioxidants and phytonutrients, lemon peel supports the immune system, enhancing the body’s ability to ward off infections and recover from illness more efficiently.
4. Aids Digestion and Gut Health
Lemon peel is a good source of pectin, a fiber that feeds beneficial gut bacteria, improves digestion, and helps prevent constipation and indigestion. The enzymes in lemon zest may also help stimulate bile production, contributing to smoother digestive processes.
5. May Help Dissolve Gallstones
Research suggests that d-limonene, a compound in lemon peels, may act as a natural cholesterol solvent, supporting the treatment and possible prevention of gallstones. However, more studies are needed for conclusive evidence.
6. Reduces the Risk of Cancer
Lemon peels contain flavonoids like salvestrol Q40 and d-limonene, which have been studied for their potent anticancer properties in laboratory and animal research. While lemon peel cannot cure cancer, regular intake may help lower risk factors and inhibit growth of cancer cells, especially in the stomach.
7. Maintains Oral Health
The antibacterials in lemon peel help inhibit bacteria that cause gum disease, tooth decay, and oral infections. Their Vitamin C content is also crucial in preventing scurvy and promoting overall gum health.
8. Supports Bone Health
With high levels of calcium and vitamin C, lemon peels help maintain strong bones and connective tissue. These nutrients may prevent osteoporosis and bone-related disorders, although additional clinical studies are warranted.

9. Helps Maintain Healthy Body Weight
The pectin fiber in lemon peels promotes satiety, reduces appetite, and may lower the absorption of sugars, thereby assisting weight management efforts.
10. Detoxifies and Cleanses the Body
Natural detoxifying components in lemon peel, including antioxidants and fibers, support liver health and aid the body in removing toxins, supporting clean and efficient metabolism.
11. Fights Infections
Lemon peel demonstrates antimicrobial and antifungal properties that help slow the growth of certain bacteria and fungi, potentially reducing the risk of ear infections, colds, and urinary tract infections. While promising, further research is necessary to confirm all these effects.

Lemon Peel for Skin and Beauty
12. Promotes Clearer, Brighter Skin

- Mix dried lemon peel powder with yogurt or honey for a rejuvenating facial mask.
- Always dilute with a carrier oil and patch test on a small area before full use, as citrus may irritate sensitive skin.
13. Combats Skin Infections
Lemon peel’s antimicrobial properties help soothe and prevent minor skin infections, supporting overall skin health.

14. Natural Cleaning Solution
Lemon peels provide a safe, eco-friendly alternative to synthetic cleaning products. Their essential oils (notably d-limonene) have antibacterial and antiviral properties, leaving surfaces clean and fresh-smelling.
- Soak lemon peels in white vinegar for 2 weeks, strain, and dilute with water to make a powerful all-purpose cleaner.
- Use lemon peels to polish metal, clean microwaves, and refresh cutting boards.
15. Air Freshener and Natural Deodorizer
Lemon peels absorb odors and release a refreshing citrus scent. Simply leave a bowl of lemon peels in the kitchen, fridge, or bathroom to neutralize unpleasant smells. Simmer peels in water and herbs for a DIY air freshener.
How to Use Lemon Peels Safely
