Common Digestive Side Effects
As with many high-fiber or nutrient-dense supplements, the most frequently reported side effects of Field of Greens are digestive in nature. When a person suddenly increases their intake of prebiotic fiber and concentrated plant compounds, their gut microbiome may need time to adjust.
Bloating and Gas
Bloating is a very common complaint with greens powders like Field of Greens, and it can be inconsistent and frustrating. The ingredients most often blamed include fiber (specifically inulin, which is in Field of Greens), prebiotics, and natural sweeteners like stevia. For many, this symptom is temporary and subsides as the body gets used to the new fiber intake. Staying well-hydrated is key to helping the body process the fiber effectively.
Diarrhea and Constipation
Some individuals may experience loose stools or even diarrhea, particularly when first starting the supplement. This can occur when a sudden influx of fiber and prebiotics puts the gastrointestinal tract into overdrive. On the other end of the spectrum, a smaller number of people may experience constipation if the powder is high in insoluble fiber and they are not drinking enough water. Easing into the full serving size can help mitigate these symptoms.
Nausea
Less commonly, some individuals may feel nauseous after consuming Field of Greens. This can be due to digestive sensitivity or the body's reaction to a high concentration of ingredients. Drinking the supplement with food or reducing the serving size initially may help.
Concerns Regarding Ingredients and Safety
Several aspects of Field of Greens' formulation raise concerns for some consumers, particularly regarding transparency and independent verification.
Proprietary Blends
Field of Greens is made using proprietary blends, meaning the company does not disclose the specific quantity of each ingredient. While the total amount of each blend is listed, it is impossible for consumers to know if they are receiving clinically effective or even safe doses of each component. This lack of transparency can be a major drawback for those who want precise nutritional information.
Lack of Third-Party Testing
Another significant safety concern is the absence of information regarding third-party testing for Field of Greens. Independent testing by organizations like ConsumerLab or NSF International is crucial for verifying a supplement's purity, potency, and freedom from contaminants. Without this testing, consumers cannot be certain that the product is free from harmful substances like heavy metals, which have been detected in some greens powders in the past.
Allergic Reactions
Field of Greens is manufactured in a facility that processes common allergens, including milk, eggs, soybeans, shellfish, peanuts, fish, wheat, and tree nuts. This poses a risk of cross-contamination for individuals with severe allergies. Anyone with known food sensitivities should read the label carefully and exercise caution.
Potential for Allergic Reactions and Medication Interactions
Allergic Responses
While rare, allergic reactions to greens powders are possible. Ingredients such as wheatgrass or algae can trigger a reaction in susceptible individuals. Symptoms can range from mild sinus issues, like sneezing or congestion, to more severe skin reactions, such as rashes or hives. If you have a known allergy to any ingredient listed on the label, you should avoid the product.
Medication Interactions
The high concentration of nutrients in greens powders can sometimes interfere with certain medications.
- Vitamin K: The leafy greens (e.g., kale, spinach) in Field of Greens contain high levels of vitamin K. This vitamin is essential for blood clotting and can interfere with the effectiveness of blood-thinning medications. Individuals on blood thinners must consult their doctor before taking any greens powder.
- Caffeine: The 'Charged' version of Field of Greens contains added caffeine from organic matcha powder. This can cause jitters, increased heart rate, or stomach discomfort in sensitive individuals, especially if they are also consuming other caffeinated products.
Ways to Minimize Potential Side Effects
- Start Slowly: Begin with a smaller serving size to allow your body to adjust to the new ingredients and fiber content. Gradually increase your intake over a week or two.
- Stay Hydrated: Drink plenty of water throughout the day to help with digestion and reduce the risk of constipation.
- Take with Food: Consuming the powder with a meal can help prevent nausea or other stomach upset.
- Check Ingredients: If you have any allergies or sensitivities, carefully review the label for ingredients that may cause a reaction.
- Consult a Professional: Always speak with a healthcare provider or a registered dietitian before starting a new supplement, especially if you have an existing medical condition or are taking prescription medication.

Conclusion
While Field of Greens offers a convenient way to supplement your intake of organic fruits and vegetables, it is not without potential side effects. The most common issues are mild and digestive, but the use of proprietary blends and the lack of third-party testing present more significant concerns regarding safety and ingredient quality. Serious interactions with medication, particularly blood thinners, and allergic risks are also important to consider. As with any new supplement, the decision to take Field of Greens should be made with careful consideration and, ideally, after consulting a healthcare professional.

Final Thoughts on Supplementing with Greens
For those seeking to fill dietary gaps, integrating whole foods remains the gold standard. A greens powder can be a practical addition, but it should not replace fresh produce. Be an informed consumer by researching products, reading labels carefully, and understanding your own health needs and sensitivities before committing to a daily supplement.
