What is Alfalfa?
Alfalfa, known scientifically as Medicago sativa, is a plant in the legume family. Often called lucerne or purple medick, it’s a leafy green that grows in many warm and temperate regions around the world.[1]
People have grown alfalfa for over 2,000 years, giving it a long history. Its name comes from the Arabic phrase meaning “father of all foods,” highlighting its nutritional value and use as both food and medicine.[2]
Today, alfalfa is available in several forms, including fresh sprouts, dried leaves, and supplements. Each form offers different benefits, making alfalfa a versatile choice for people interested in their health.[3]
Historical Uses of Alfalfa
Traditional Medicine
Throughout history, people have used alfalfa for its healing properties. Ancient cultures, including the Chinese, used it for digestive and kidney issues, recognizing its potential to treat various health problems.[4]
Native American tribes also valued alfalfa for its ability to improve overall health. Some cultures traditionally made tea from its leaves, using it to address conditions such as arthritis and other inflammatory issues.[5]
Agricultural Importance
Farmers have long used alfalfa as an excellent feed for livestock. Animals like cows, horses, and sheep benefit from alfalfa’s high protein content, making it a valuable part of their diet.[6]
Alfalfa’s deep roots also improve soil quality. They help add nitrogen to the soil and improve its overall structure, benefiting other crops. Farmers often rotate alfalfa with other crops to enhance soil health and productivity.[7]
Nutritional Profile
Alfalfa contains a range of nutrients, including vitamins, minerals, and antioxidants. This high nutrient density makes it a useful dietary supplement. Let’s explore the specific nutrients it offers.[8]
| Nutrient | Amount per 100g |
|---|---|
| Vitamin K | 30% DV |
| Vitamin C | 5% DV |
| Folate | 3% DV |
| Manganese | 3% DV |
| Copper | 3% DV |
| Iron | 2% DV |
Alfalfa also provides smaller amounts of calcium, potassium, and magnesium, in addition to beneficial plant compounds like saponins, flavonoids, and phytoestrogens.[9]
Compared to other leafy greens, alfalfa contains more protein than many vegetables. Its vitamin K content is higher than that of spinach, and while it doesn’t have as much calcium as kale, it still provides this mineral, making it a helpful addition to a balanced diet.[10]
Health Benefits
Digestive Health
Alfalfa’s fiber content may help support healthy digestion by moving food through the intestines. This can aid in preventing constipation and promote regular bowel movements. Some individuals find it helps soothe upset stomachs.[11]
The prebiotics in alfalfa can feed beneficial bacteria in the gut, helping to support a balanced gut microbiome. This can improve nutrient absorption, support the immune system, and contribute to overall health, though more research is needed in this area.[12]
Cholesterol Management
Research suggests that alfalfa might play a role in managing cholesterol levels by potentially lowering LDL cholesterol, often referred to as “bad” cholesterol, which can help support heart health.[13]
The saponins found in alfalfa may help prevent the absorption of cholesterol in the gut. Also, the fiber content can bind to cholesterol and help remove it from the body, working together to contribute to healthy cholesterol levels.[14]
Antioxidant Properties
Alfalfa is a source of antioxidants, compounds that protect cells from damage by fighting free radicals. This protection can help prevent cell damage that contributes to aging.[15]
The antioxidants in alfalfa include:
- Vitamin C
- Vitamin E
- Beta-carotene
- Flavonoids
These antioxidants help support overall cellular health and may reduce inflammation in the body. While some studies suggest they may lower the risk of chronic diseases, further research is needed to confirm these potential benefits in humans.[16]
Bone Health
Alfalfa provides minerals, such as calcium and magnesium, that support healthy bones. Vitamin K in alfalfa also helps the body use calcium effectively, contributing to bone strength.[17]
Some research indicates that alfalfa might help prevent osteoporosis, a condition that weakens bones. The nutrients it provides may support bone density and maintain bone strength as we age, although more studies are required to confirm this effect.[18]
Forms and Consumption
Alfalfa Sprouts
Alfalfa sprouts are a common way to consume the plant because they are easy to grow at home. They have a fresh, crisp texture and can be a great addition to salads and sandwiches, offering a concentrated source of nutrients with low calories and high vitamin content.[19]
To grow alfalfa sprouts:

Sprouts should always be eaten fresh and washed thoroughly to reduce the risk of foodborne illness. They should also be stored in the refrigerator and consumed within a few days.[20]
Supplements
Alfalfa supplements are available in tablets, powders, and teas, each with its own benefits. Tablets are convenient for daily use, powders can be added to smoothies, and teas offer a soothing way to enjoy alfalfa.[21]
When choosing alfalfa supplements, it’s important to select quality products from reputable brands that have been third-party tested to ensure purity and potency. It’s also important to always follow dosage instructions on the label and consult with a healthcare provider before starting any new supplement.[22]
Culinary Uses
Alfalfa’s mild flavor makes it a versatile addition to many dishes. Here are some ways to use alfalfa in cooking:
- Add sprouts to sandwiches for crunch
- Toss dried leaves into soups or stews
- Sprinkle alfalfa powder into smoothies
- Use as a garnish for salads or entrees
Alfalfa pairs well with light flavors such as cucumber, avocado, or citrus fruits, adding a fresh touch to both light and heavier dishes. Experimenting with different combinations can help you discover your favorite ways to include it in your meals.[23]
Safety and Precautions
Potential Side Effects
While most people tolerate alfalfa well, some may experience side effects. These can include:
