Organic Kale Powder
Also known as: Kale Leaf Powder, Brassica oleracea, Kale Extract Powder, Dried Kale Powder
Kale powder is a concentrated whole-food form of kale leaves, a cruciferous vegetable rich in vitamins K, C, A, and bioactive compounds like sulforaphane and lutein. While kale itself is nutrient-dense, evidence for specific health claims from supplemental powder forms is limited compared to whole-food consumption.
Primary uses
- Nutritional supplementation
- Antioxidant support
- General wellness
How it works
- Provides glucosinolates (precursors to sulforaphane)
- Contains lutein and zeaxanthin (carotenoids)
- Supplies vitamin K for bone and clotting factors
- Delivers polyphenols with antioxidant properties
Dosage
- Typical range
- 1-2 teaspoons (3-6 grams) daily
- Timing
- Any time of day; commonly added to smoothies or beverages
- With food
- Best absorbed with foods containing fat (e.g., smoothie with nut butter or coconut oil)
- Duration
- Safe for long-term daily use as a food supplement
- Special populations
- Those taking warfarin or other anticoagulants should maintain consistent vitamin K intake and consult healthcare provider
Forms
- Powder· 70/100
Safety
Common side effects
- Generally well-tolerated
- Possible mild digestive discomfort if taken in large quantities
Contraindications
- Individuals on warfarin should monitor vitamin K consistency (kale is high in vitamin K)
- Thyroid conditions: raw or high-dose cruciferous vegetables may contain goitrogens; cooking/powdering reduces this risk
Evidence notes
Kale as a whole food is well-documented as nutrient-dense; however, evidence for supplemental powder forms is moderate and largely extrapolated from whole-food studies. Bioavailability and efficacy of dried/powdered forms requires more human research.
Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
