5 Best Wheatgrass Supplements (2026) · Expert Reviewed

Q: What is the difference between wheatgrass juice powder and wheatgrass powder?

Wheatgrass powder is made by dehydrating and grinding the whole leaf, including the cellulose fiber. Wheatgrass juice powder is made by juicing the fresh grass first, then dehydrating the juice — producing a 25:1 concentrate. Juice powder contains significantly more chlorophyll, enzymes, and micronutrients per gram because the indigestible fiber has been removed.

Q: Does wheatgrass contain gluten?

Wheatgrass harvested before the jointing stage (when the grain kernel forms) is gluten-free, despite coming from the wheat plant. All reputable wheatgrass supplements are harvested at this early growth stage. However, people with celiac disease should look for products that are tested and certified gluten-free to rule out cross-contamination.

Q: What are the proven health benefits of wheatgrass?

Research shows wheatgrass has antioxidant and anti-inflammatory properties (Bar-Sela 2007), may support blood production in thalassemia patients by reducing transfusion needs (Marwaha 2004), and has shown promise for ulcerative colitis symptom relief (Ben-Arye 2002). Some evidence suggests blood sugar regulation benefits (Shakya 2016). The evidence is emerging but encouraging.

Q: How much wheatgrass should I take daily?

For whole-leaf powder, 3-8g daily is the typical range. For juice powder concentrate, 3-6g daily is sufficient due to the higher nutrient density. This is roughly equivalent to 30-60ml (1-2 oz) of fresh wheatgrass juice. Start with a lower dose and increase gradually over a week to assess tolerance.

Q: Can wheatgrass cause side effects?

Wheatgrass is generally safe, but some people experience nausea, headache, or diarrhea — especially when starting with a high dose. These effects usually resolve within a few days. Taking wheatgrass with food or in a smoothie reduces digestive discomfort. People with grass allergies should use caution, and those on blood-thinning medications should consult their doctor due to wheatgrass's vitamin K content.

Q: Is wheatgrass better as a powder or tablet?

Powders allow flexible dosing and are more cost-effective per serving. Juice powders specifically offer the highest nutrient concentration. Tablets eliminate the grassy taste entirely but require swallowing 6-7 pills per serving and cost more per serving. If taste is not a concern, powder is the better choice. If taste is a dealbreaker, tablets are a practical alternative.

Q: Is organic wheatgrass worth the extra cost?

Yes. Wheatgrass is consumed as a whole food without extraction or purification, so any agricultural chemicals used during growing end up directly in your serving. USDA Organic certification ensures no synthetic pesticides or fertilizers were used. The cost difference between organic and conventional wheatgrass is typically small.

Q: Can I take wheatgrass while pregnant or breastfeeding?

There is insufficient research on wheatgrass safety during pregnancy or breastfeeding. While it is a whole food, the concentrated supplement form delivers higher-than-dietary doses of certain compounds. Consult your healthcare provider before using wheatgrass supplements during pregnancy or nursing.

Q: Amazing Grass Wheat Grass Powder (60 servings): Are there any potential interactions with medications?

Amazing Grass Wheat Grass Powder (60 servings) contains Organic Whole-Leaf Wheatgrass Powder. As with any wheatgrass supplement, consult your healthcare provider if you take prescription medications, especially blood thinners, blood pressure medications, or immunosuppressants. Amazing Grass recommends consulting a doctor before use if you are on medication.

Q: Amazing Grass Wheat Grass Powder (60 servings): Are there any side effects from long-term use?

At 8g per serving (1 scoop), Amazing Grass Wheat Grass Powder (60 servings) provides a clinically effective dose within the studied range of 3-8g wheatgrass powder daily. Long-term use at recommended doses is generally well-tolerated based on available research. Discontinue and consult a healthcare provider if you experience adverse effects.

How We Evaluate

Every product is scored against these weighted criteria. Our ratings reflect clinical evidence and product quality, not commission rates.

Juice Powder vs Whole-Leaf

30%

Juice powders are made by dehydrating fresh wheatgrass juice, concentrating nutrients up to 25:1. Whole-leaf powders include the fiber but dilute the chlorophyll and enzymes. This is the single biggest quality differentiator.

Organic Certification

20%

USDA Organic certification matters for wheatgrass because it is typically consumed as a whole food without extraction. Pesticide residues in non-organic grasses are consumed directly.

Chlorophyll Content

20%

Chlorophyll is the key bioactive compound in wheatgrass, comprising up to 70% of dry weight. Higher chlorophyll correlates with antioxidant and anti-inflammatory benefits.

Third-Party Testing

15%

Independent lab testing verifies heavy metal levels, microbial safety, and label accuracy. Grass supplements can accumulate contaminants from soil.

Value per Serving

15%

Cost per serving adjusted for nutrient density. A 3g juice powder serving delivers more bioactives than an 8g whole-leaf serving, making direct price comparison misleading.
