Greenherb supplies a premium, nutrient-dense Kale Powder, crafted from fresh, organically grown kale leaves (Brassica oleracea var. sabellica), one of the most nutrient-rich leafy greens in the world. Our organic kale powder is produced using gentle low-temperature drying and fine milling processes to preserve the vegetable's vibrant green color, mild earthy flavor, and exceptional profile of vitamins, minerals, chlorophyll, and beneficial phytochemicals. This versatile, clean-label ingredient offers a convenient, shelf-stable solution for boosting nutritional value, adding natural color, and enhancing the health profile of a wide range of food, beverage, and dietary supplement products. Available in both whole leaf powder and concentrated kale juice powder formats, we provide flexible options for manufacturers seeking the best organic kale powder for their formulations.
We support global B2B customers with consistent quality, scalable supply, and comprehensive analytical documentation, enabling the creation of innovative products that meet the growing consumer demand for convenient, plant-based superfood nutrition.
One of Nature's Most Nutrient-Dense Superfoods – Kale is widely recognized as a nutritional powerhouse, containing exceptionally high levels of vitamin K (supporting bone health), vitamin A (beta-carotene for vision and immunity), vitamin C (antioxidant and immune support), and manganese, along with B vitamins, copper, calcium, and potassium. Our organic kale powder delivers this comprehensive nutrient profile in a convenient, concentrated form .
Rich in Chlorophyll for Detoxification & Alkalizing Support – Abundant in chlorophyll—the "green blood" of plants—kale powder supports the body's natural detoxification pathways, promotes alkalizing balance, and provides gentle internal cleansing benefits. Chlorophyll's molecular structure closely resembles human hemoglobin, supporting healthy blood and oxygen transport .
Excellent Source of Antioxidants & Anti-Inflammatory Compounds – Contains significant levels of flavonoids (kaempferol, quercetin) and phenolic acids (ferulic acid, caffeic acid), along with the glucosinolate-derived isothiocyanate sulforaphane. These compounds provide potent antioxidant protection and support healthy inflammatory balance throughout the body .
Supports Bone Health with Vitamin K & Calcium – Kale is one of the richest plant sources of vitamin K1 (phylloquinone), essential for bone mineralization and the activation of osteocalcin—a protein that binds calcium to bone matrix. Combined with naturally occurring calcium, magnesium, and phosphorus, our kale juice powder offers comprehensive skeletal support .
Promotes Healthy Vision & Eye Protection – Provides lutein and zeaxanthin, carotenoids that accumulate in the macula of the eye, filtering harmful blue light and protecting against oxidative damage associated with age-related vision decline. These compounds are naturally preserved in our gentle processing .
Gentle Digestive Support with Prebiotic Fiber – The dietary fiber content supports regular bowel movements, feeds beneficial gut bacteria as a prebiotic, and promotes satiety. Unlike some green powders that can be harsh, kale powder is well-tolerated and gentle on digestion .
Certified Organic & Clean-Label – Our kale powder is available as certified organic kale powder, non-GMO, gluten-free, and free from major allergens. The clean-label nature of kale—simply "kale powder" on ingredient lists—appeals to consumers seeking transparent, whole-food ingredients .

Greenherb's Kale Powder transforms one of the world's most celebrated superfoods into a versatile, year-round ingredient for modern food and wellness product development. Kale has been cultivated for over 2,000 years, but its explosion in popularity over the past decade is no fad—it is backed by an extraordinary nutritional profile that few leafy greens can match . From its exceptional vitamin K content (a single serving provides several times the daily requirement) to its concentrated lutein and zeaxanthin for eye health, and from its sulforaphane precursors for detoxification support to its gentle fiber for digestive wellness, kale offers a comprehensive range of benefits in a single ingredient . Our organic kale powder captures all of this nutritional intelligence in a convenient, shelf-stable form, available as both whole leaf powder (for maximum fiber content) and kale juice powder (for higher concentration and solubility). It is the ideal choice for brands developing products in the green superfoods, whole-food nutrition, detoxification support, and natural food colorant categories, offering a recognizable, consumer-trusted ingredient with proven health-promoting properties.
Botanical Source: Brassica oleracea L. var. sabellica (Curly Kale, Scotch Kale)
Used Part: Whole Leaves (organic cultivation)
Key Active Components: Vitamin K1 (phylloquinone), Vitamin A (beta-carotene), Vitamin C (ascorbic acid), Lutein, Zeaxanthin, Chlorophyll, Glucosinolates (precursors to sulforaphane), Flavonoids (kaempferol, quercetin), Dietary Fiber, Calcium, Magnesium, Potassium .
Standardization: Available as whole leaf powder (with full fiber) and kale juice powder (concentrated, more soluble) .
Appearance: Fine, vibrant green to deep green powder with characteristic kale aroma
Flavor: Mild, slightly earthy, with fresh green notes—pleasant and versatile
Solubility: Whole leaf powder disperses well in liquids; kale juice powder offers improved solubility for clear beverages
Certifications: USDA Organic, EU Organic, Halal, Kosher (as required)
Our gentle process ensures the preservation of heat-sensitive vitamins, chlorophyll, and glucosinolates:
Organic Cultivation & Harvest: Kale is grown on certified organic farms and harvested at peak nutrient density. Leaves are selected for vibrant color and absence of yellowing or damage.
Thorough Washing & Cleaning: Fresh kale is washed multiple times in cool, clean water to remove any soil, debris, or field residues.
Sorting & Trimming: Leaves are sorted, and tough stems are trimmed. Only tender leaf material is used for premium powder.
Blanching (Minimal): A brief, gentle steam blanching may be used to inactivate enzymes that could cause nutrient degradation or color loss during drying, while preserving the vibrant green hue .
Low-Temperature Drying: The prepared kale is gently dried using controlled low-temperature air drying or freeze-drying (lyophilization) technology, which removes moisture while preserving heat-sensitive vitamins, chlorophyll, and glucosinolates .
Fine Milling: The dried kale is milled into a fine, consistent powder using specialized equipment that prevents excessive heat generation.
Juice Powder Processing (Optional): For kale juice powder, the fresh kale is first cold-pressed to extract the nutrient-rich juice, which is then low-temperature concentrated and spray-dried with a minimal food-grade carrier.
Sieving & Standardization: The powder is sieved to achieve uniform particle size and blended for batch-to-batch consistency in color, flavor, and nutritional profile.
Quality Assurance: Each batch is tested for nutritional composition, color value, microbial safety, heavy metals, and moisture content.
Kale Powder is valued for its comprehensive, whole-food nutritional profile:
Supports Bone Health & Mineralization*: Exceptionally rich in vitamin K1, which activates osteocalcin—the protein responsible for binding calcium to bone matrix. Combined with calcium, magnesium, and phosphorus naturally present in kale, this provides comprehensive skeletal support .
Provides Potent Antioxidant & Anti-Inflammatory Protection*: The flavonoids (kaempferol, quercetin) and glucosinolate-derived sulforaphane help neutralize free radicals, protect cells from oxidative stress, and modulate pro-inflammatory mediators .
Supports Healthy Vision & Eye Protection*: Contains lutein and zeaxanthin, carotenoids that accumulate in the macula, filtering harmful blue light and protecting against oxidative damage associated with age-related macular degeneration .
Promotes Natural Detoxification*: Chlorophyll supports the body's phase II liver detoxification enzymes and binds to certain toxins, aiding their elimination. Glucosinolates are converted to isothiocyanates that enhance detoxification pathways .
Supports Immune System Function*: Vitamins A, C, and K, along with flavonoids and sulforaphane precursors, contribute to healthy immune cell function and antioxidant protection for the immune system .
Supports Cardiovascular Health*: The combination of fiber, antioxidants, and anti-inflammatory compounds helps maintain healthy cholesterol levels, supports vascular function, and promotes overall heart health .
Promotes Digestive Health & Regularity*: The dietary fiber content supports regular bowel movements, acts as a prebiotic to nourish beneficial gut bacteria, and promotes satiety .
Alkalizing & pH Balancing*: Kale is an alkalizing green that helps balance the body's pH, supporting overall metabolic health .
