Dandelion roots provide 45 calories per 100 grams, with a macronutrient breakdown of 68% carbohydrates (9g total, 4g fiber), 20% protein (3g), and 12% fat (1g), alongside standout micronutrients including 190mg calcium (19% DV), 7mg iron (88% DV), 5070μg vitamin A (563% DV), and 35mg vitamin C (39% DV). This nutritional profile positions dandelion root as a low-calorie, nutrient-dense food source rich in antioxidants and minerals.
Nutritional Composition
Per 100 grams of dried dandelion root, the energy content is approximately 45 kcal, primarily from complex carbs like inulin, a prebiotic fiber that constitutes much of the 4g dietary fiber. Proteins contribute 3g, offering essential amino acids uncommon in roots, while fats remain minimal at 1g, mostly unsaturated.
Vitamin A dominates at 5070μg (563% DV), derived from beta-carotene precursors, supporting vision and immunity. Iron levels hit 7mg (88% DV), vital for oxygen transport, and calcium provides 190mg (19% DV) for bone health.
| Nutrient | Amount per 100g | % Daily Value |
|---|---|---|
| Calories | 45 kcal | - |
| Carbohydrates | 9g | 3% |
| Fiber | 4g | 13% |
| Protein | 3g | 6% |
| Fat | 1g | 1% |
| Vitamin A | 5070μg | 563% |
| Vitamin C | 35mg | 39% |
| Calcium | 190mg | 19% |
| Iron | 7mg | 88% |
| Sodium | 76mg | 3% |
Key Vitamins and Minerals
Dandelion roots excel in fat-soluble vitamin A, with levels exceeding 5000μg per 100g, far surpassing daily needs and linked to reduced oxidative stress in studies from 2012. Vitamin C at 35mg bolsters collagen synthesis and immunity.
Minerals like iron (7mg) aid anemia prevention, while calcium (190mg) supports skeletal integrity; a 2025 analysis noted dandelion's mineral bioavailability rivals spinach. Trace elements including potassium (around 600mg per cup equivalent) regulate fluids.
- Vitamin A: 5070μg (563% DV) - Eye health, immune function.
- Vitamin C: 35mg (39% DV) - Antioxidant, iron absorption.
- Calcium: 190mg (19% DV) - Bone density.
- Iron: 7mg (88% DV) - Blood production.
- Fiber: 4g (13% DV) - Gut health via inulin.
Macronutrient Breakdown
Carbohydrates dominate at 9g per 100g, with net carbs at 6g after subtracting 4g fiber, making it suitable for low-glycemic diets. Inulin, a fructan, feeds beneficial gut bacteria, as confirmed in Nutrition Reviews (September 2012).
Protein content (3g) is notable for a root vegetable, providing about 20% of caloric value and essential for muscle repair. Fats are low (1g), with no saturated or trans fats reported.
Health Benefits Supported by Data
Historically used since the 10th century in Chinese medicine, dandelion root exhibits diuretic effects, reducing bloating by 20% in a 2012 Oxford study on Taraxacum officinale. Its inulin improves insulin sensitivity.
"Dandelion root's diverse biological activities include antioxidant and anti-inflammatory properties," states a 2012 review in Nutrition Reviews. Modern data from 2026 shows 27% DV iron per serving aids vegetarians.
Antioxidant capacity rivals blueberries in ORAC scores, per USDA updates through 2025, protecting against cellular damage.
Dandelion root supports liver detoxification, with polysaccharides enhancing bile production by up to 30% in clinical trials dated March 2023.
Historical and Cultural Context
Native to Eurasia, dandelion roots were roasted as coffee substitutes during World War II rationing in Europe, providing sustenance with 45 kcal/100g. By 1950, French pharmacopeias listed it for digestive aid.
In Traditional Chinese Medicine since 659 AD, it's documented in Yaoxing Lun for "clearing heat"; 2025 foraging revivals cite 88% DV iron as key.
- Harvest roots in fall for peak inulin (up to 40% dry weight).
- Wash thoroughly to remove soil.
- Dry at 95°F for 4 hours or roast at 350°F for coffee-like flavor.
- Store in airtight jars; shelf life exceeds 2 years.
- Brew as tea: 1 tsp per cup, steep 10 minutes.
Preparation Methods
For optimal nutrient retention, steam or dry dandelion roots rather than boil, preserving 90% of vitamin C per 2026 SnapCalorie analysis. Powdered forms deliver 563% DV vitamin A per tablespoon.
Roasted roots mimic coffee, with zero caffeine but 3g protein boost; add to smoothies for fiber.
Scientific Studies and Stats
A 2012 Oxford Academic review analyzed 20 studies, finding dandelion root extracts reduce inflammation markers by 25% in vitro. Iron absorption reaches 15% bioavailability, outperforming spinach in 2025 tests.
Population data: In a 2023 Korean cohort of 500 participants, daily dandelion tea correlated with 12% lower fasting glucose. ORAC value: 15,000 μmol TE/100g, top 10% of roots.
| Study Year | Key Finding | Metric |
|---|---|---|
| 2012 | Diuretic effect | 20% urine output increase |
| 2023 | Glucose control | 12% reduction |
| 2025 | Iron bioavailability | 15% |
| 2026 | Nutrient density | 27% DV iron/serving |
Comparisons to Common Foods
Versus carrots, dandelion roots triple vitamin A (563% vs 167% DV) but match calories at 45 kcal/100g. Beats potatoes in iron (88% vs 6% DV) with half the carbs.
- Per 100g: Dandelion iron 7mg vs beet 0.8mg.
- Calcium: 190mg vs kale 150mg (fresh).
- Fiber: 4g matches sweet potato.
Culinary and Supplement Uses
Incorporate into broths for umami; 2025 trends show 30% rise in root powder sales for gut health. Teas yield 39% DV vitamin C per cup.
Supplements standardize to 500mg inulin, matching 100g fresh root's prebiotic load.
"Unearthing dandelion roots reveals their treasure: unmatched mineral density in a humble weed," notes Gardening Soul, May 13, 2025.
Potential Risks and Considerations
Allergies affect 15% of ragweed-sensitive individuals; pesticide residues in wild harvests pose risks-opt for organic. High vitamin A warrants moderation in pregnancy.
This breakdown, drawn from USDA-aligned data through 2026, underscores dandelion root's role as a superfood weed, with 563% DV vitamin A and 88% iron per serving driving its resurgence. Forage responsibly for maximal nutritional value.
Key concerns and solutions for Dandelion Roots Nutritional Value Better Than You Think
How does dandelion root compare calorically to other roots?

Can you eat dandelion roots raw?
Yes, raw dandelion roots are edible, offering crisp texture and full nutrients, though peeling reduces bitterness; start with small amounts to avoid digestive upset.
Is dandelion root safe daily?
Up to 10g dried daily is safe for most, per 2012 reviews, but consult doctors if on diuretics due to potassium interactions.
How much dandelion root equals daily iron needs?
80g provides 88% DV for women (18mg), making it efficient; pair with vitamin C for full absorption.
Does cooking reduce nutrients?
Boiling leaches 20-30% water-soluble vitamins like C, but roasting preserves 95%; dry methods best.
