To take barley grass powder, measure the serving stated on your product label, add it to cool or room-temperature water, mix until evenly dispersed and drink it soon after preparation. Because whole-leaf and juice powders can have different concentrations, use the scoop or sachet supplied with your product rather than copying another brand’s measurement.
A green drink should be simple enough to repeat. The challenge is that “barley grass powder” can describe different products, from dried whole leaves to concentrated juice powder. That is why the best way to drink barley grass powder begins with the label—not a universal spoonful found online.
This guide explains how to mix it smoothly, when to drink it, how to improve the flavour and which common mistakes to avoid.
Product note: BARLEYGREEN® Premium is described by the brand as a dried juice preparation made from organic young barley grass, with organic tapioca maltodextrin, organic brown-rice extract and kombu extract. Always compare this article with the current packaging in your possession.
Key takeaways
- Check whether your product is whole-leaf powder, juice powder, an extract or a blended formula.
- Measure with the supplied scoop or sachet and follow the physical label.
- BARLEYGREEN® currently recommends room-temperature or cold water and drinking the mixture soon after preparation.
- There is no strong evidence that every person must take barley grass on an empty stomach.
- If it causes nausea or digestive discomfort, stop and seek appropriate advice rather than forcing a routine.

What you need before you start
Prepare these items:
- The original product container or sachet
- Its supplied scoop, if included
- A clean, dry glass or shaker
- Cool or room-temperature drinking water
- A clean spoon, whisk or shaker ball
Before opening the powder, check the expiry date, seal, ingredient list, serving directions and storage instructions. If the package has been damaged, the powder smells unusually musty or the product has become wet and clumped, contact the seller or manufacturer before using it.
Identify the type of powder
| Product description | What it usually means | Why it affects preparation |
|---|---|---|
| Whole-leaf powder | Dried leaves have been milled | Often contains more structural leaf material |
| Juice powder | Juice is separated from the leaves and dried | May be more concentrated by weight |
| Extract | Selected compounds are concentrated | Serving size may be smaller and product-specific |
| Blended formula | Barley grass plus carriers or other ingredients | Taste, nutrition and directions depend on the blend |
Do not assume that one teaspoon of a whole-leaf powder equals one teaspoon of a juice powder. The 2026 scientific review of young-barley preparations highlights substantial differences in preparation and a lack of standardised dosing across studies.
How to take barley grass powder step by step
Step 1: Read the current serving directions
Use the physical package as the primary reference. Website content and older articles may not reflect the exact version, pack size or market you purchased.
If the label and a website disagree, contact the manufacturer before proceeding. Do not increase the serving because an influencer, testimonial or unrelated brand recommends more.
Step 2: Measure the labelled serving
Use the included scoop or one complete sachet when the label defines that as a serving. A household teaspoon or tablespoon is not a precise unit because spoon shapes and how tightly powder is packed can change the amount.
If the label gives the serving in grams but no scoop is supplied, a small digital kitchen scale is more reliable than estimating by eye.
Step 3: Add cool or room-temperature water
The current BARLEYGREEN® Premium directions recommend room-temperature or cold water. This follows the manufacturer’s intended use for its processed juice powder.
Avoid boiling water unless the specific label says otherwise. Heat can change heat-sensitive components, while very hot liquid may also make green powders taste more bitter or form clumps.
Step 4: Mix thoroughly
Put water in the glass first, then sprinkle the powder over the surface. Stir briskly for 20–30 seconds, or close a shaker and shake until the drink looks evenly dispersed.
Some settling is normal because a plant powder is a suspension rather than a fully dissolved clear beverage. Stir again if the drink sits for several minutes.
Step 5: Drink it soon after preparation
The brand recommends consuming BARLEYGREEN® soon after mixing. Preparing only what you plan to drink also reduces the chance of contamination from leaving a mixed beverage at room temperature.
If you must prepare it in advance, follow the product’s storage directions and normal food-safety practice. Do not leave a smoothie containing milk, yoghurt or cut fruit unrefrigerated.
When is the best time to drink barley grass powder?
There is no well-established clinical evidence that one clock time produces better health outcomes for everyone. The most practical time is one you can follow consistently without nausea, medicine conflicts or inconvenience.
Morning
Morning is popular because it is easy to connect the drink with an existing routine. Keep it separate from a medicine only if the medicine’s label or your pharmacist instructs you to do so.
Before a meal
The current BARLEYGREEN® Premium page recommends taking the product before meals. Treat this as product guidance rather than a proven universal rule for all barley powders.
If taking it before food causes nausea or discomfort, stop and ask the manufacturer or a healthcare professional whether another timing approach is appropriate.
With or after food
Some people tolerate supplements better with food. However, meals can also affect certain medicines and nutrients. Anyone taking prescription medication should ask a pharmacist whether the supplement and medicine need to be separated.
Evening
An evening serving may suit someone’s routine, but there is no good evidence that barley grass improves sleep. If drinking liquid late at night interrupts sleep or causes reflux, use an earlier time.
Five easy ways to make barley grass taste better
Keep additions simple so the drink does not quietly become high in sugar or calories.
1. Chilled plain water
This is the easiest way to understand the product’s original flavour. Use the water quantity suggested by the label, then adjust slightly for taste without changing the powder serving.
2. Unsweetened soy or oat beverage
A small amount can soften the grassy taste. Check for personal allergens and remember that the nutrition profile will now include the added beverage.
3. Banana smoothie
Blend the labelled serving with half a banana, cool water and ice. Banana adds sweetness and body without requiring syrup.
4. Apple and cucumber blend
Blend a small piece of apple with cucumber, water and ice before adding the powder. This gives a fresher taste while keeping the recipe simple.
5. Plain yoghurt bowl
Stir the powder into plain yoghurt and top with fruit if the product label allows food mixing. This is an option for people who dislike drinking green powder, but it is not suitable for every diet.
| Preparation | Best for | Watch out for |
|---|---|---|
| Water | Simplest routine | Natural grassy taste |
| Smoothie | Softer flavour | Added sugar and calories |
| Plant beverage | Creamier texture | Allergens and sweetened versions |
| Yoghurt | Spoonable option | Dairy intolerance and refrigeration |
What should you not mix with barley grass powder?
Very hot liquid
Follow the manufacturer’s temperature directions. BARLEYGREEN® currently advises cool or room-temperature liquid, so boiling water is not recommended for that product.
Multiple new supplements
Adding several powders, herbs and high-dose vitamins at once makes it difficult to identify the cause of nausea, allergy or another reaction. Introduce only one new product at a time when a qualified professional considers it appropriate.
Medicine without checking
Do not mix prescription medicine into the drink. Take medicines exactly as directed and ask a pharmacist about timing. This is especially important for warfarin, thyroid medicine, diabetes medicine and medicines affected by food or minerals.
Excess sweeteners
Honey, syrup, sweetened juice and flavoured yoghurt can make a green drink much higher in free sugar. If the goal is a simple daily supplement, begin with water or an unsweetened mixer.
Common preparation mistakes
- Copying another brand’s scoop. Product concentration and scoop volume can differ.
- Confusing teaspoons and tablespoons. They are not interchangeable.
- Using a wet scoop. Moisture can cause clumping and may shorten product quality after opening.
- Doubling the serving after missing a day. Resume the labelled routine; do not “catch up.”
- Assuming more is better. Higher intake can increase cost and possible adverse effects without proven added benefit.
- Using it as a vegetable replacement. A powder does not provide the variety, texture and full food matrix of a balanced diet.
- Ignoring symptoms. Persistent nausea, diarrhoea, rash or dizziness deserves attention, not a “detox” label.

How to store barley grass powder
Follow the package instructions. In general:
- Close the container immediately after use.
- Store it in a cool, dry place away from direct sunlight and steam.
- Keep the scoop clean and dry.
- Do not use a bathroom shelf or the humid area beside a kettle.
- Keep the product out of reach of children.
- Do not use it after the expiry date or if the seal was compromised.
Processing and storage can affect compounds in young barley preparations. The 2026 review notes that vitamin C and enzyme activity can be sensitive to heat, oxygen and processing, while mineral content is more stable.
Frequently asked questions
Can I drink barley grass powder every day?
Use frequency should follow the specific product label and your individual health circumstances. Daily use does not guarantee a particular outcome, and more is not necessarily better. Ask a doctor or pharmacist before routine use if you are pregnant, have kidney disease, take warfarin or use other regular medicine.
Should I drink barley grass on an empty stomach?
Some product directions recommend taking it before meals, but strong clinical evidence does not establish an empty stomach as universally superior. Follow your product label. If that timing causes nausea, stop and ask whether a different time is suitable rather than forcing the routine.
Can I mix barley grass powder with juice?
Yes, if the product directions allow it. Choose a modest amount of unsweetened juice and remember that juice adds natural sugar and calories. Water remains the simplest option. People monitoring blood glucose or potassium should choose mixers with advice suited to their care plan.
Can I put barley grass powder in hot water?
Check your product directions. BARLEYGREEN® currently recommends cool or room-temperature water and advises against hot water. Because products are processed differently, do not generalise this instruction to every brand without reading its label.
Why does barley grass powder settle at the bottom?
Plant particles do not always dissolve completely, so some settling can be normal. Stir or shake again before finishing the drink. If the dry powder has an unusual smell, moisture damage, mould or unexpected discolouration, do not use it and contact the manufacturer.
How much water should I use?
Start with the amount stated on the package. If no water volume is provided, use enough to mix the labelled powder into a comfortable drink without changing the serving. Adding more water changes the strength of the taste, not the amount of powder consumed.
Conclusion
The best answer to how to take barley grass powder is straightforward: identify the product form, measure the labelled serving, mix it with the liquid recommended by the manufacturer and choose a time you can tolerate consistently.
Keep the routine simple, avoid copying another product’s measurement and stop if you develop concerning symptoms. For a quantity-focused guide, continue to How Much Barley Grass Powder Should You Take per Day?, or review the current BARLEYGREEN® Premium product information.
