Overview Information

Spinach is a vegetable. The leaves are used for food and to make medicine.

Spinach is used for obesity, memory and thinking skills (cognitive function), fatigue, cancer, and many other conditions, but there is no good scientific evidence to support these uses.

How does it work?

Spinach contains vitamins and other nutrients.


Uses & Effectiveness?

Insufficient Evidence for

  • Memory and thinking skills (cognitive function). Early research shows that eating spinach with lunch does not help to improve attention or memory in healthy adults.
  • Obesity. Early research shows that taking a spinach product before breakfast might increase weight loss by a small amount.
  • Stomach and intestinal complaints.
  • Fatigue.
  • Stimulating growth in children.
  • Promoting recovery from illness.
  • Other conditions.
More evidence is needed to rate the effectiveness of spinach for these uses.

Side Effects

Side Effects & Safety

When taken by mouth: Spinach is LIKELY SAFE for most people when used as a food. It is POSSIBLY SAFE when used in larger, medicinal amounts.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Spinach is LIKELY SAFE during pregnancy and breast-feeding when used in food amounts. There isn't enough reliable information to know if spinach is safe to use as a medicine. Stay on the safe side and stick to food amounts.

Children: Eating spinach as a food is LIKELY SAFE for children who are more than 4 months old. But spinach is LIKELY UNSAFE for infants that are less than 4 months old. The nitrates in spinach can sometimes cause a blood disorder (methemoglobinemia) in young infants.

Allergies: People who are sensitive to latex or certain molds are more likely to have allergic responses to spinach. Also, people who are allergic to foods like chard and beets are more likely to have allergic responses to spinach.

Diabetes: Spinach might lower blood sugar levels. Some doctors worry that it might make blood sugar levels drop too low if used along with diabetes medications. If you use spinach in medicinal amounts and take diabetes medications, monitor your blood sugar closely. The dose of your diabetes medications might need to be changed. Check with your healthcare provider.

Kidney disease: Spinach may cause hard crystals to form in the kidneys. These crystals won't dissolve and might make kidney disease worse.

Surgery: Spinach might lower blood sugar levels. Some doctors worry that it might interfere with blood sugar control during and after surgery. Stop using spinach in medicinal amounts at least 2 weeks before a scheduled surgery.



Moderate Interaction

Be cautious with this combination

  • Medications for diabetes (Antidiabetes drugs) interacts with SPINACH

    Spinach might decrease blood sugar. Diabetes medications are also used to lower blood sugar. Taking spinach along with diabetes medications might cause your blood sugar to go too low. Monitor your blood sugar closely. The dose of your diabetes medication might need to be changed.
    Some medications used for diabetes include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), chlorpropamide (Diabinese), glipizide (Glucotrol), tolbutamide (Orinase), and others.

  • Warfarin (Coumadin) interacts with SPINACH

    Spinach contains large amounts of vitamin K. Vitamin K is used by the body to help blood clot. Warfarin (Coumadin) is used to slow blood clotting. By helping the blood clot, spinach might decrease the effectiveness of warfarin (Coumadin). Be sure to have your blood checked regularly. The dose of your warfarin (Coumadin) might need to be changed.



The appropriate dose of spinach depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for spinach. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
