Alfalfa powder comes from dried, ground alfalfa leaves. It supplies vitamin K along with calcium, magnesium, potassium, and chlorophyll in a concentrated form.
People mix the powder into water, juice, or smoothies as a daily nutrient booster. The fiber and enzymes can support comfortable digestion while a mild diuretic effect helps the body shed excess fluid. Some take it to help keep cholesterol numbers inside the normal range.
Alfalfa contains meaningful amounts of vitamin K, so anyone on anticoagulant drugs should check with their doctor before using it.
