Wheatgrass is a nutrient-rich type of young grass in the wheat family that is sold in a variety of forms as a dietary supplement. Wheatgrass does provide a concentrated amount of nutrients, including iron, calcium, magnesium, amino acids, chlorophyll, and vitamins A, C and E. Wheatgrass fans say that its rich nutrient content boosts immunity, kills harmful bacteria in your digestive system, and rids your body of waste. Wheatgrass may also be promoted as a good way to help meet your daily target for vegetable servings. However, there are few research studies about wheatgrass, so it’s difficult to assess such health claims.Wheatgrass isn’t a miracle cure and shouldn’t replace either your regular medical care or a healthy diet that includes plenty of fresh fruits and vegetables. But used sensibly and in moderation, wheatgrass may add interest to your diet.
