❓ Quick Answers
What is wheatgrass good for?
Wheatgrass may support cardiovascular health, immune function, and antioxidant defense. Research suggests it contains chlorophyll, flavonoids, and vitamins C and E[Evidence: D][2] with potential applications in managing cardiovascular health and gastrointestinal disorders[Evidence: D][1]. However, human studies remain limited.
How much wheatgrass should I drink per day?
Research studies have used 3.5 grams of freeze-dried wheatgrass powder daily for cardiovascular benefits[Evidence: B][3], while cancer supportive care studies used 60cc (about 2 ounces) of fresh wheatgrass juice daily[Evidence: C][4]. Start with smaller amounts to assess tolerance.
What are the side effects of wheatgrass?
Clinical trials report no adverse events associated with wheatgrass consumption[Evidence: D][2]. Wheatgrass has a safe tolerability profile in studied populations. However, individuals with wheat or grass allergies should exercise caution, and long-term safety data beyond 18 months is limited.
Is there scientific evidence for wheatgrass benefits?
Yes, but evidence quality varies. Two randomized controlled trials support cardiovascular and quality-of-life benefits[Evidence: B][3][11]. Multiple laboratory studies confirm antioxidant activity increased 1.55x[Evidence: C][5] and anti-inflammatory effects[Evidence: C][7]. More human trials are needed.
What nutrients are in wheatgrass?
Wheatgrass contains chlorophyll, vitamins (C, E, A), minerals (iron, magnesium, calcium), amino acids, flavonoids, and phenolic compounds[Evidence: D][10]. Proteomics research has identified 297 proteins including peroxidases, superoxide dismutases, and cytochromes[Evidence: C][5].
🔬 How Does Wheatgrass Work?
Think of wheatgrass as nature's chemical factory, producing a diverse arsenal of protective compounds during its rapid 7-10 day growth period. Like a tiny power plant generating multiple types of clean energy, wheatgrass synthesizes chlorophyll, flavonoids, and enzymes that work together to support your body's defense systems.
The Chlorophyll Connection
Chlorophyll—the compound that gives wheatgrass its vibrant green color—shares a remarkable structural similarity to hemoglobin in your blood. Imagine chlorophyll as hemoglobin's plant cousin: both molecules have nearly identical structures, differing only in their central metal atom (magnesium in chlorophyll versus iron in hemoglobin). This structural similarity may contribute to wheatgrass's traditional use in supporting blood health, though human evidence remains preliminary.[Evidence: D][1]
Antioxidant Activity
Laboratory research reveals wheatgrass's impressive antioxidant capacity. Proteomics studies identified 297 proteins in wheatgrass, with peroxidases, superoxide dismutases, and cytochromes abundantly present[Evidence: C][5]. Antioxidant activity increased 1.55x after 16 days of growth, with DPPH radical scavenging reaching 15%, 22%, and 30% at successive growth stages[Evidence: C][5].
Anti-Inflammatory Pathways
Wheatgrass compounds appear to work through multiple anti-inflammatory mechanisms. In vitro studies show wheatgrass reduces nitric oxide production in macrophages and suppresses inflammatory cytokines TNF-α, IL-6, and IL-1β[Evidence: C][7]. Key bioactive compounds apigenin and myo-inositol bind to COX-2 protein, a major inflammatory enzyme[Evidence: C][7].
Animal studies demonstrate wheatgrass-derived polysaccharides inhibit NF-κB signaling pathways—master regulators of inflammation—while attenuating hepatic cell death through caspase-3 modulation[Evidence: C][8].
Cardiovascular Mechanisms
A randomized controlled trial in hyperlipidemic women revealed that 3.5g freeze-dried wheatgrass daily produced significant reductions in atherogenic lipoproteins: 5.4% decrease in total cholesterol, 4.4% reduction in LDL cholesterol, and 9.5% reduction in triacylglycerols[Evidence: B][3]. Significant reductions in Apo B fraction (p=0.016) suggest potential for reducing cardiovascular disease risk[Evidence: B][3].
Cancer Supportive Care
Preliminary research suggests wheatgrass may support patients undergoing chemotherapy. In colorectal cancer patients, 60cc daily wheatgrass juice resulted in significantly higher IL-10 concentrations and reduced white blood cell decline during adjuvant chemotherapy[Evidence: C][4]. Additional research found reduced exosome markers, lower vascular damage markers, and reduced blood clotting markers in the wheatgrass group—suggesting wheatgrass may reduce chemotherapy-related thrombogenicity[Evidence: C][12].
Despite these promising preliminary findings, wheatgrass's role in colorectal cancer remains minimally investigated, with evidence limited despite clinical interest[Evidence: D][9]. Reviews note wheatgrass shows anti-inflammatory, antioxidant, and anticancer properties, but identify significant gaps requiring further investigation[Evidence: D][9].
Skin and Inflammation Support
Research combining wheatgrass with aronia demonstrates dual benefits for inflammatory skin conditions. In vitro and in vivo studies show this combination suppresses inflammatory response and reduces oxidative stress, ameliorating overall symptoms of atopic dermatitis in mice[Evidence: C][6].

⚠️ Risks, Side Effects, and Warnings
Study Limitations
While safety data from clinical trials is reassuring, important gaps exist. Reviews note that all trials to date were small with methodological problems[Evidence: D][2]. Evidence comes from limited studies requiring more rigorous validation[Evidence: D][1]. Future research is necessary before clinical recommendations can be made[Evidence: C][4].
🥗 Practical Ways to Use Wheatgrass
1. Morning Wellness Shot
The most common approach is a 1-2 oz wheatgrass juice shot first thing in the morning. If the taste is challenging, follow immediately with a slice of orange or apple. Research supporting chemotherapy patients used this approach with 60cc daily[Evidence: C][4].
2. Smoothie Integration
Mix 1 teaspoon of wheatgrass powder into fruit smoothies. The natural sweetness of banana, mango, or pineapple masks the grassy flavor while preserving nutritional benefits. Add spinach or kale to create a comprehensive green blend.
3. Powder in Beverages
For the cardiovascular protocol studied in clinical trials, 3.5g freeze-dried wheatgrass powder can be encapsulated or stirred into water or juice[Evidence: B][3]. This provides a convenient, shelf-stable option for consistent daily intake.
4. Skin Applications
Research on wheatgrass combined with aronia for skin conditions suggests topical potential[Evidence: C][6]. Some people apply fresh wheatgrass juice to minor skin irritations, though human topical studies are limited.
5. Growing Your Own
Home cultivation ensures maximum freshness. Plant wheat berries in shallow trays with organic potting soil, keep moist, and harvest at 7-10 days when grass reaches 6-8 inches. This timing corresponds to peak nutrient content according to proteomics research[Evidence: C][5].
Storage Tips
- Fresh juice: Consume immediately or refrigerate up to 24 hours
- Fresh grass: Refrigerate up to 7 days; harvest as needed
- Powder: Store in cool, dry place away from light; check expiration date

Frequently Asked Questions
Does wheatgrass really work?
The evidence is mixed but cautiously promising. Two randomized controlled trials provide Level B evidence: one demonstrated significant cholesterol reductions (5.4% total cholesterol, 4.4% LDL, 9.5% triglycerides) in hyperlipidemic women after 10 weeks, while another showed quality of life improvements in thalassemic children over 18 months. However, reviews acknowledge all trials were small with methodological problems, and a gap exists between basic science findings and clinical applications. Wheatgrass shows measurable effects in research settings, but more rigorous human trials are needed to establish definitive clinical recommendations.
When is the best time to drink wheatgrass juice?
Most practitioners recommend consuming wheatgrass on an empty stomach, ideally 15-30 minutes before breakfast. This timing may optimize nutrient absorption by avoiding competition with other foods for digestive resources. The cancer supportive care studies had patients consume 60cc of wheatgrass juice daily as part of their routine during chemotherapy cycles. If you experience nausea or digestive discomfort when taking wheatgrass on an empty stomach, try consuming it with a small amount of food. Consistency matters more than exact timing—choose a time that fits your schedule and stick with it.
Is wheatgrass powder or juice better?
Both forms have demonstrated benefits in research, but the choice depends on your priorities. Fresh wheatgrass juice was used in cancer supportive care studies showing immune benefits, suggesting it retains active enzymes and compounds. However, the cardiovascular RCT used 3.5g freeze-dried wheatgrass powder in encapsulated form and achieved significant lipid reductions, demonstrating that processed forms retain efficacy. Fresh juice offers maximum enzyme activity but requires immediate consumption. Freeze-dried powder provides convenience, precise dosing, and longer shelf life while preserving most nutritional benefits.
Can wheatgrass help with cancer treatment?
Preliminary research suggests potential supportive care benefits during chemotherapy, but wheatgrass is not a cancer treatment. In colorectal cancer patients, daily wheatgrass juice during adjuvant chemotherapy resulted in significantly higher IL-10 concentrations and reduced white blood cell decline. Additional research found reduced vascular damage markers and lower blood clotting markers in the wheatgrass group, suggesting it may reduce chemotherapy-related thrombogenicity. However, wheatgrass's role in colorectal cancer remains minimally investigated. Cancer patients should always consult their oncology team before using any supplements.
Is wheatgrass safe during pregnancy?
No specific safety data for wheatgrass during pregnancy or lactation exists in the 2015-2025 published literature. While clinical trials in other populations report no adverse events and indicate a safe tolerability profile, pregnancy was not specifically studied. The precautionary principle suggests pregnant and breastfeeding women should consult their healthcare provider before using wheatgrass. If you're pregnant or nursing and interested in wheatgrass, discuss the potential benefits and unknown risks with your obstetrician or midwife before adding it to your regimen.
