Introduction
Barley grass juice powder, made from the young, tender leaves of the barley plant (Hordeum vulgare), has gained quite a following internationally as a nutrient-packed superfood. It looks so fresh (when processed super carefully) and smells just like freshly-mown grass. It is convenient and easy to incorporate into smoothies at low levels to get a nutritional boost without affecting flavor too much. But beyond its fresh appeal, scientific research has also shown that it may help people with inflammatory conditions. Barley grass juice powder has been put to the test for a wide variety of issues, like inflammatory bowel diseases and joint pain, both of which are fairly common maladies. In this article, we'll explore three studies that examine how it might help for 3 different conditions: ulcerative colitis, liver damage, and rheumatoid arthritis.
Barley Grass Juice for Ulcerative Colitis
A 2002 study by Ben-Arye and colleagues, published in Scandinavian Journal of Gastroenterology, investigated the effects of wheat grass juice (a close cousin of barley grass juice) on active distal ulcerative colitis, a chronic inflammatory bowel disease. In this randomized, double-blind, placebo-controlled trial, patients drank either 100 ml (about 3.4 fluid ounces) of wheat grass juice or a placebo daily for a month. The results? The people in the group consuming wheat grass juice experienced significant reductions in disease activity, including reduced rectal bleeding and abdominal pain, compared with the placebo group.
As good as these results were, they were achieved with an inferior product. That's right. The wheatgrass in this study was grown in trays, not in deep soil, over a few months. This wheat grass was grown in a tray for a few days and then juiced.
What difference does that make? The flavonoids and complex compounds were not fully developed in the product that they used, yet they still got decent results. That means that, from a superior product, you could expect at least these results, and possibly better, as it would have a higher concentration of anti-inflammatory flavonoids.
What this means for you: If you’re dealing with ulcerative colitis or similar gut issues, barley grass juice might offer complementary support, along with other things you are doing. We aren't saying that it will cure you at all. But its anti-inflammatory properties could help soothe flare-ups as they did for people in the study.
Protecting the Liver from Inflammation
In a 2017 study published in Phytotherapy Research, Nepali and colleagues explored a wheatgrass-derived polysaccharide (again, closely related to barley grass) in mice with lipopolysaccharide (LPS)-induced liver injury. LPS, a bacterial toxin, triggers intense inflammation that can harm the liver. The study found that the polysaccharide reduced inflammation, oxidative stress, and cell death in the liver, protecting it from damage.
What this means for you: While this study was in mice, we can see that various compounds, like polysaccharides, in barley grass could support liver health under inflammatory conditions. So, if you have liver issues, maybe barley grass products would be a good supportive food for you to add to your diet.
Easing Rheumatoid Arthritis Symptoms
A 1998 study by Cremer and colleagues, published in Romanian Archives of Microbiology and Immunology, examined a green barley extract’s effects on cells from rheumatoid arthritis patients. Rheumatoid arthritis is an autoimmune condition marked by chronic joint inflammation. The study found that the barley extract reduced the release of tumor necrosis factor-alpha (TNF-alpha) and reactive oxygen species (ROS), both key drivers of inflammation in arthritis.
What this means for you: If you’re managing rheumatoid arthritis or other inflammatory joint conditions, barley grass juice might help modulate your immune system’s overactive responses. It’s not a cure, but it could be a natural way to complement your treatment plan.
Barley Grass Juice Powder: A Natural Way to Quench Inflammation
Together, these studies bring out barley grass juice’s potential to address inflammation in specific health contexts. Whether it’s calming gut inflammation, protecting vital organs like the liver, or easing joint pain, barley grass offers a versatile approach to wellness. And it's a natural, nutrient-rich, whole food supplement that appeals to those who are seeking holistic health solutions, like you.
Here are Some Ways to Drink Barley Grass Juice
- Smoothies: Blend a teaspoon of barley grass juice powder into your morning smoothie. One teaspoon won't mess up the flavor much (says me, who has been drinking this kind of stuff for more than 25 years).
- Water or Juice: Mix a teaspoon with water or orange juice, grape juice, or pineapple juice. Or make a small shot of it and chase it with something much tastier as a reward.
- Capsules: Not so sure about that green drink stuff? We have BarleyMax in capsules as well.
- Tip: Start with a small dose, like a ¼ of a teaspoon if you are sensitive to foods, to see how your body responds. If you have chronic conditions or you're taking medications, it would be a good idea to check with a nutritionally-minded healthcare provider.

Frequently Asked Questions About Barley Grass Juice
Here are the questions I hear most often from people who are considering adding barley grass juice to their health routine. I have tried to answer them honestly, including where the science is still early and where I have personal experience to draw from.
Is barley grass juice powder the same as wheatgrass juice?
No, but they are close cousins. Both are young cereal grasses harvested before the stalk and grain heads form, and both belong to the grass family. Barley grass (Hordeum vulgare) and wheatgrass (Triticum aestivum) share a very similar nutrient and phytochemical profile, including chlorophyll, antioxidant enzymes, flavonoids, and polysaccharides.
That is why research on one often applies reasonably well to the other. The studies in this article used wheatgrass in the gut and liver experiments, and a green barley extract in the arthritis experiment. I feel comfortable drawing general conclusions across both because the mechanism, fighting inflammation at the cellular level, is driven by compounds they both contain.
That said, BarleyMax is barley grass, not wheatgrass. And if you are strictly avoiding gluten, barley grass juice powder is typically gluten-free when harvested before the grain develops, but you should check the testing documentation on any product you buy. Our BarleyMax testing is available on the Raw Food Lab page.
How does barley grass juice help with ulcerative colitis?
The short answer is that it reduces inflammation in the gut lining. Ben-Arye and colleagues tested 100 ml of wheatgrass juice daily against a placebo in people with active distal ulcerative colitis. The wheatgrass group saw significant reductions in rectal bleeding and abdominal pain over a one-month period.
Mechanistically, barley and wheat grass are rich in polysaccharides, chlorophyll, and antioxidant enzymes like superoxide dismutase. These compounds help calm the overactive inflammatory response that drives colitis flares. Chlorophyll in particular has a structural resemblance to hemoglobin, and there is evidence that it helps maintain healthy gut mucosa.
I want to be clear that just because barley grass juice is helpful, that doesn't mean it's a replacement for your medical treatment plan. If you are managing ulcerative colitis, work with your doctor. But adding a nutrient-dense anti-inflammatory green juice powder to your routine is a safe, low-risk step that the research supports.
Can barley grass juice protect my liver?
The animal study by Nepali and colleagues showed something interesting. A polysaccharide extracted from wheatgrass protected mouse livers against LPS-induced injury, a model of the liver stress that occurs during severe bacterial infections and systemic inflammation.
The protection came from three directions: reduced inflammatory cytokine activity, lower oxidative stress markers, and less programmed cell death in liver cells. So the grass polysaccharide was doing three jobs at once.
Now, this was in mice, not people. I would not tell someone with serious liver disease to replace their treatment with barley grass juice. What I would say is that the mechanisms identified in this study, anti-inflammatory, antioxidant, and anti-apoptotic, are the same mechanisms we want to support through diet anyway. And barley grass juice is a whole-food source of exactly those kinds of compounds.
Does barley grass juice help with rheumatoid arthritis?
The in vitro study by Cremer and colleagues gave us a window into one specific mechanism. They applied a purified green barley extract to cells from rheumatoid arthritis patients and measured two key inflammation drivers: TNF-alpha and reactive oxygen species. Both went down.
TNF-alpha is one of the main cytokines that drives joint destruction in rheumatoid arthritis. It is actually the target of several major rheumatoid arthritis medications. So finding a plant compound that moderates its release is significant, even if the study was done outside the body.
I don't want to overpromise results here. In vitro results do not always translate to clinical outcomes in people. But the mechanism is real, the compound class (flavonoids and antioxidant enzymes in barley grass) is well-studied, and the risk of adding a green juice powder to your anti-inflammatory diet is essentially zero. It is a reasonable addition to a broader approach.
How much barley grass juice powder should I take?
The clinical study on ulcerative colitis used 100 ml (about 3.4 fluid ounces) of fresh wheatgrass juice daily. A rough equivalent in powder terms depends on the concentration of your specific product.
For BarleyMax, I suggest starting with one teaspoon (about 2.5 grams) once a day mixed into water, juice, or a smoothie. If you are sensitive to new supplements or have digestive issues, start with a quarter teaspoon and work up. Your body is telling you something if you react.
Some people take two servings daily, morning and evening. I have been using barley grass juice products for more than 25 years, and I have neither experienced nor heard of any toxicity at normal dietary amounts. The capsule form is also available for people who are not ready for the green drink experience.
Is BarleyMax gluten-free?
Yes. BarleyMax is harvested from young barley grass leaves before the stalk and grain head develop. The gluten protein in barley is found in the grain, not in the young leaf. Independent lab testing confirms that BarleyMax does not contain detectable gluten.
Can I take barley grass juice while on medications?
In most cases, yes, but with some caveats you should know about.
Barley grass juice is high in vitamin K from its chlorophyll content. Vitamin K is involved in blood clotting. If you are taking a blood thinner like warfarin (Coumadin), consistent intake of green vegetables is fine, but you want to keep it consistent rather than dramatically fluctuating. Sudden large increases in vitamin K-containing foods can affect your INR values. Talk to your prescribing physician.
Otherwise, barley grass juice is a food. It is not a concentrated pharmaceutical extract. The interactions documented in the literature are minimal. That said, I always recommend working with a nutritionally-minded healthcare provider if you are managing a complex health condition with multiple medications. The goal is to have someone on your team who understands both.
How is BarleyMax different from other barley grass products?
Most barley grass supplements on the market are made from dried whole leaf, which means you are consuming the fibrous cell wall along with the nutrients. The nutrients remain locked in the dried cells. BarleyMax is a juice powder, meaning the juice is extracted first and then dried at low temperature. This removes the insoluble fiber and concentrates the bioavailable nutrients.
Why does that matter? The phytochemicals, antioxidant enzymes, chlorophyll, and flavonoids that show anti-inflammatory activity in the research are water-soluble. They come out in the juice. The fibrous cell wall is a carrier, not the active ingredient.
We also do independent laboratory testing of every batch to verify potency and purity. That testing is published publicly. When I say BarleyMax is the best barley grass product available, I am not just saying it because I work here. I am saying it because I have seen the data.
