MEASURED NUTRIENT ROLES
Top nutrients that support the body
For 100 g, the strongest Daily Value contributions among nutrients available in this record are Vitamin K (17.1% DV), Thiamin (B1) (4.7% DV) and Copper (3.7% DV). The cards explain the normal roles of those nutrients, not a treatment effect of the food.
Vitamin K: blood clotting and bone metabolism
This amount provides 20.5 µg. Vitamin K is needed for normal blood clotting and proteins involved in bone metabolism. This describes the nutrient’s normal role, not disease prevention or treatment.
Read the NIH/FDA nutrient referenceThiamin (B1): energy and cell function
This amount provides 0.06 mg. Thiamin helps turn food into energy and supports normal cell growth and function. This describes the nutrient’s normal role, not disease prevention or treatment.
Read the NIH/FDA nutrient referenceCopper: iron metabolism and nerves
This amount provides 0.03 mg. Copper supports energy production, connective tissue, iron metabolism, and normal nervous and immune function. This describes the nutrient’s normal role, not disease prevention or treatment.
Read the NIH/FDA nutrient referenceManganese: metabolism and antioxidant enzymes
This amount provides 0.08 mg. Manganese supports metabolism, bone formation and antioxidant enzyme systems. This describes the nutrient’s normal role, not disease prevention or treatment.
Read the NIH/FDA nutrient referencePotassium: fluid balance and muscles
This amount provides 139 mg. Potassium supports normal cell function, fluid balance, nerve transmission and muscle contraction. This describes the nutrient’s normal role, not disease prevention or treatment.
Read the NIH/FDA nutrient referenceVitamin B6: metabolism and brain development
This amount provides 0.04 mg. Vitamin B6 supports many enzyme reactions involved in metabolism, brain development and immune function. This describes the nutrient’s normal role, not disease prevention or treatment.

Food-specific benefits & evidence
Contributes Vitamin K
This amount provides 20.5 µg. Vitamin K is needed for normal blood clotting and proteins involved in bone metabolism. This is a measured nutrient contribution, not proof that the food prevents or treats disease.
