Special precautions and warnings

If you plan on using wheatgrass as a medicine, you need to consult your doctor.

Since not much is known about its effects to breastfeeding and pregnant women, stay on the safe side and refrain from using it if you’re expecting or nursing.

If you have a medical condition and feel that wheatgrass may help you improve it, talk to your doctor before self-medicating. Don’t discontinue your medication or change your diet without an official advice from your physician.

Even though wheatgrass could be good for health, it can cause constipation, nausea, and appetite loss.

It can also trigger some sensitivity and allergic reactions such as hives and swelling of the throat. If you develop allergic reactions, immediately discontinue use and go to the doctor right away.

As of now, there’s no information about wheatgrass and its interaction with foods and other drugs. If you are in a special diet or are taking medications, consult your doctor first before using any form of wheatgrass.

Dosage and Forms

Even though wheatgrass is natural, you still need to be careful because there’s no study about what constitutes safe dosage.

To answer the question, how to eat wheatgrass, consider the following:

Currently, wheatgrass comes in tablet and powder forms. Often, the powder form is blended in water. Some people also add a spoonful of the powder in smoothies or fruit juices.

Others choose to juice wheatgrass by cutting its base and inserting the tips into the juicer. Please note that you will only be able to obtain small amounts of juice at a time. To have 1 ounce serving, you need half a cup of raw, fresh wheatgrass juice. Most people find the taste too strong, so they mix it with smoothies and fruit juices.

Finally, to eat wheatgrass fresh, cut its stalks and serve with other strong-tasting fruits.

Key Takeaways
