Wheatgrass Supplements: Forms and How to Choose

Wheatgrass is a popular superfood rich in vitamins, minerals, chlorophyll, and phytochemicals that may help boost energy levels, support digestive functions, and enhance overall health. 

Discover common forms of wheatgrass supplements and learn how to choose the best product for your health needs and routine.

What is wheatgrass, and what does it do? 

Wheatgrass refers to the young shoots of the common wheat plant, also known as Triticum aestivum, which is harvested just before the plant matures and forms grain. 

At this critical growth stage, wheatgrass contains the highest concentration of bioactive compounds such as antioxidants and phytonutrients. Its high nutrient density helps protect the young, fragile plant from environmental stressors as it develops.

These same nutrients can also support human health, making wheatgrass a popular dietary supplement. 

It’s valued for its high concentration of chlorophyll, vitamins, minerals, enzymes, and plant compounds that help support healthy immune function and promote overall cellular health.

Wheatgrass offers several nutrients associated with various health benefits, including:

• Vitamins A, C, D, E, and K
• B-complex vitamins 
• Calcium
• Iron
• Magnesium
• Plant-protein and essential amino acids
• Enzymes
• Chlorophyll

Because of its broad nutrient profile and concentrated plant compounds, wheatgrass is a popular way to boost plant-based nutrition, support energy production, digestive health, and overall well-being.

What forms of wheatgrass are used in supplements? 

Wheatgrass supplements are primarily available as whole-leaf powders or juice powders, which can be mixed into beverages such as water or smoothies. 

Whole leaf powders are made by drying and finely grinding the entire grass blade, which preserves the plant’s natural fibers along with its full spectrum of nutrients. 

“Juice powders are made by extracting the juice from fresh wheatgrass and then freeze-drying the liquid to preserve its nutrients,“ explains Dr. Berg. “This creates a more concentrated product that delivers many of the plant’s water-soluble nutrients without the added bulk of dietary fiber.”

In addition to loose powder, wheatgrass is available in capsules and tablets. These forms contain either whole-leaf powder or wheatgrass juice powder in pre-measured amounts, making them a convenient, flavor-neutral option for those seeking a simple alternative to loose powders.

How much wheatgrass do supplements typically provide? 

The amount of wheatgrass in supplements can vary widely depending on the product type and brand, but most provide between roughly 1.5 and 12 g per serving.

Whole-leaf wheat grass is commonly used in a serving size of one tablespoon, providing roughly 8 to 12 g. Some brands use smaller one-teaspoon scoops, which deliver 2.5 to 3.5 g per serving. 

Wheatgrass powder retains its natural fiber content, which makes up a significant portion of the serving. As an example, an 8 g serving of whole wheatgrass powder may contain up to 4 g of fiber.

In contrast, wheatgrass juice powders are more concentrated than whole powders, which explains why serving sizes are typically smaller–often between 1.5 and 5 g.

Capsules and wheatgrass tablets tend to contain smaller amounts of wheatgrass per unit, often around 300 to 600 mg per pill. As a result, a full serving may require several capsules or tablets to reach a total intake comparable to approximately 1.5 to 3 g of powder.

Factors that can influence wheatgrass selection 

Various factors can influence the type of wheatgrass product that best suits your needs. 

The processing method is one consideration. Processing involves either drying the entire young grass or extracting the juice before drying, both of which influence nutrient density, taste, and texture. 

Pure juice supplements provide a concentrated dose of bioavailable nutrients the body can readily absorb and utilize, while whole-leaf supplements contain all of the plant’s constituents, including dietary fiber.  

Whole-leaf wheatgrass supplements tend to have a more grassy flavor and a gritty texture, while juice products are typically smoother and milder.

The fiber content can also influence your choice in a wheat grass product. Juice supplements contain little to no fiber, while whole wheatgrass contains significant amounts of insoluble fiber. 

Research published in Frontiers in Nutrition found that, while insoluble fiber can’t be digested, it may support bowel regularity, which may be ideal for those looking to support gut motility and overall digestive health. 

Wheatgrass juice powder may be best for those seeking concentrated, comprehensive nutritional support, while whole wheatgrass powder is ideal for those who prefer a whole-plant approach.

Capsules and tablets can be a good option for individuals who dislike the taste of wheatgrass or prefer a convenient and pre-measured alternative to powder forms.

How to choose a wheatgrass supplement 

When choosing a wheatgrass supplement, it’s vital to carefully read the ingredient list to avoid products with artificial flavors, added sugar, or other non-nutritive fillers. 

Look for products with clear labeling, stating “raw wheatgrass juice powder” or “organic wheatgrass powder,” and minimal, natural ingredients to help ensure it suits your wellness goals.

Additionally, consider quality and certifications, such as non-genetically modified (GMO) and organic wheatgrass, to maximize nutritional value and health benefits while minimizing exposure to pesticides, such as glyphosate. 

Glyphosate and other potential chemical toxins used on wheat crops have been linked to significant health risks. 

Research published in the International Journal of Molecular Sciences highlights, “Glyphosate seems to exert a significant toxic effect on neurotransmission and to induce oxidative stress, neuroinflammation and mitochondrial dysfunction.”

Finally, though wheatgrass is naturally gluten-free, choosing a product that is certified gluten-free can help prevent cross-contamination, which may be especially important for individuals with gluten sensitivity, wheat allergy, or celiac disease.
