Lemon juice contains a small amount of potassium, approximately 103 mg per 100 ml, contributing to your daily intake.
Lemon juice is more than just a tangy addition to your water or recipes. This citrus powerhouse packs essential nutrients, including potassium. But how much potassium does lemon juice actually contain, and what benefits does it offer? Let’s squeeze out the facts.
Potassium Content in Lemon Juice
Fresh lemon juice contains approximately 49mg of potassium per 100ml. While this isn’t as high as banana or avocado, it’s a significant amount for a citrus juice. The potassium in lemon juice plays crucial roles in:
- Muscle function
- Nerve signaling
- Blood pressure regulation
- Fluid balance
Comparing Lemon Juice to Other Potassium Sources
| Food | Potassium per 100g |
|---|---|
| Lemon juice | 49mg |
| Orange juice | 200mg |
| Banana | 358mg |
| Avocado | 485mg |
Health Benefits of Lemon Juice Potassium
The potassium in lemon juice works synergistically with other nutrients to provide multiple health benefits:
1. Kidney Stone Prevention
Studies show lemon juice can increase urinary citrate levels by 2.5 times, helping prevent calcium oxalate kidney stones. The National Institutes of Health confirms lemon juice therapy effectively raises citrate levels comparable to potassium citrate supplements.
2. Blood Pressure Regulation
Potassium helps counteract sodium’s effects on blood pressure. Combined with lemon’s flavonoids, this makes lemon water a heart-healthy choice. For more on citrus benefits, see our article on dragon fruit juice benefits.
3. Muscle Function
The potassium in lemon juice supports proper muscle contractions, including your heart muscle. This is why athletes often use lemon water as a natural electrolyte drink.
Maximizing Potassium Intake from Lemons
To get the most potassium from lemons:
- Use fresh lemons rather than bottled juice
- Include some pulp for extra fiber
- Combine with other high-potassium foods
- Make lemon water with warm (not boiling) water
Lemon Water Recipe for Potassium Boost
Try this simple recipe:
- Juice of 1/2 lemon (about 1 tbsp)
