Its seeds are packed with essential macro and micronutrients that contribute significantly to overall well-being. Unlike its lighter-colored counterpart, black kollu typically has a deeper, richer flavor and an enhanced antioxidant content.

Per 100 grams, black kollu offers a robust nutritional package:
- High in protein: Approximately 22 grams, making it an excellent plant-based protein source.
- Rich in fiber: With around 5.3 grams, it aids digestion and promotes satiety.
- Low in fat: Containing only about 0.5 grams of fat, it supports heart health.
- Excellent source of calcium: With an impressive 287 mg, it helps strengthen bones and teeth.
- High in iron: Containing roughly 6.77 mg, it helps combat anemia and boosts energy.

Scientifically-Backed Health Benefits
Beyond its nutrient profile, research supports several therapeutic properties of black kollu, validating its traditional use as a medicinal food.
Supports Healthy Weight Management
Black kollu is a popular dietary aid for weight loss due to its high fiber and protein content. This combination promotes a feeling of fullness, potentially reducing overall calorie intake. Animal studies suggest that horse gram extract may help protect against weight gain and reduce body weight, though more human research is needed. Its thermogenic properties may also help boost metabolism.
Aids Kidney Health and May Prevent Kidney Stones
Traditionally used for preventing and treating kidney stones, a soup or decoction from horse gram seeds is believed to help dissolve calcium oxalate stones. Limited animal studies indicate that horse gram extracts might inhibit the formation of these crystals due to diuretic properties and the ability to reduce oxalate levels.
Promotes Heart Health
Animal studies suggest that horse gram extract can improve heart health by reducing levels of total cholesterol, LDL cholesterol, and triglycerides. Its fiber content also helps lower cholesterol, while potassium assists in regulating blood pressure.
Boosts Digestive Health
The high dietary fiber in black kollu promotes healthy digestion and regular bowel movements. It is traditionally recognized for relieving indigestion and acting as a mild laxative. Soaking the seeds before cooking can improve digestibility.
