Does Wild Garlic Have More Vitamin C Than Lemon? The Complete Nutritional Comparison

2026-05-15

In a nutshell: Wild garlic (Allium ursinum) contains approximately 150mg of vitamin C per 100g of fresh leaves — nearly 3 times more than lemon (53mg/100g). But the reality is more nuanced: lemon is consumed in larger quantities, and wild garlic has a much broader nutritional profile. Here's the complete comparison.

1. Quick Summary: Who Wins?

Wild Garlic 🧄 Lemon 🍋
**Vitamin C** **150mg/100g** ✅ 53mg/100g
**Wins for** Vitamin C, Iron, Selenium, Fiber Citric acid, practical consumption
**Overall score** **8/10** **6/10**

In summary: Wild garlic is a vitamin C powerhouse — it contains nearly 3 times more than lemon. But lemon remains more practical for daily use. The real winner? Use them together.

2. Nutritional Profile: Wild Garlic (Allium ursinum)

Data per 100g of fresh leaves

Nutrient Per 100g % RDA Notes
Calories 30 kcal 1% Extremely light
Protein 3.5 g 7% High for a vegetable
Fiber 2.1 g 8% Good intake
**Vitamin C** **150 mg** **167%** 🔥 Exceptional — almost 2x RDA
Vitamin A (RAE) 120 µg 13%
Vitamin B6 0.35 mg 21%
Folate 60 µg 15%
**Iron** **2.7 mg** **15%** ✅ High for plant source
**Calcium** **180 mg** **18%** ✅ More than milk (120mg/100g)
Magnesium 30 mg 7%
Potassium 350 mg 10%
**Selenium** **15 µg** **27%** ✅ Rare in vegetables
Zinc 0.8 mg 7%
**Allicin** **~500 mg** — ✅ Unique sulfur compound

Why this profile: Wild garlic grows in humus-rich forest soil, absorbing minerals more efficiently than cultivated plants. Vitamin C content is particularly high in young spring leaves (March-April), and decreases with maturity and flowering.

3. Nutritional Profile: Lemon (Citrus limon)

Data per 100g of fresh juice (without peel)

Nutrient Per 100g % RDA Notes
Calories 22 kcal 1% Very light
Protein 0.4 g 1% Low
Fiber 0.3 g 1% Low (more in peel)
**Vitamin C** **53 mg** **59%** Good, but 3x less than garlic
Vitamin B6 0.06 mg 3%
Folate 8 µg 2%
Iron 0.1 mg 1% Trace
Calcium 9 mg 1% Low
Magnesium 7 mg 2%
Potassium 120 mg 3%
**Citric acid** **~5 g** — ✅ The real strength
Selenium <1 µg <2% Trace

Why this profile: Lemon is appreciated mainly for its vitamin C and citric acid content. However, it is consumed in smaller quantities (one lemon = ~30ml juice), so the actual intake per portion is lower than one might think.

4. Head-to-Head Comparison: Vitamin C and Beyond

Nutrient (per 100g) Wild Garlic 🧄 Lemon 🍋 Winner
Calories 30 kcal 22 kcal Tie
Protein 3.5g 0.4g **Wild Garlic** ✅
Fiber 2.1g 0.3g **Wild Garlic** ✅
**Vitamin C** **150mg** **53mg** **Wild Garlic** ✅ (3x)
Iron 2.7mg 0.1mg **Wild Garlic** ✅ (27x)
Calcium 180mg 9mg **Wild Garlic** ✅ (20x)
Potassium 350mg 120mg **Wild Garlic** ✅
Selenium 15µg <1µg **Wild Garlic** ✅
Allicin ~500mg 0 **Wild Garlic** ✅
Citric acid Trace ~5g **Lemon** ✅

5. Which Wins for Each Nutrient

  • ✅ Vitamin C: Wild garlic — 150mg vs 53mg (nearly 3x more)
  • ✅ Protein: Wild garlic — 3.5g vs 0.4g (9x more)
  • ✅ Iron: Wild garlic — 2.7mg vs 0.1mg (27x more)
  • ✅ Calcium: Wild garlic — 180mg vs 9mg (20x more)
  • ✅ Fiber: Wild garlic — 2.1g vs 0.3g (7x more)
  • ✅ Selenium: Wild garlic — 15µg vs trace (rare in vegetables)
  • ✅ Allicin: Wild garlic — unique sulfur compound with antibacterial properties
  • ✅ Citric acid: Lemon — its real strength, helps iron absorption

The Verdict

Wild garlic wins on almost every nutrient. Lemon's only advantage is citric acid, which paradoxically helps absorb the iron contained in wild garlic. Moral of the story: use them together.

6. How to Use Them to Maximize Vitamin C Absorption

Vitamin C is heat-sensitive and degrades with cooking. Here's how to preserve it:

1. Raw Wild Garlic Pesto (Optimal Method)

  • Blend fresh leaves with EVOO, pine nuts (or walnuts), and a squeeze of lemon
  • Preserves 90%+ of vitamin C because it's not cooked
  • The lemon adds citric acid which stabilizes vitamin C

2. Wild Garlic and Lemon Salad

  • Thinly sliced raw leaves, dressed with EVOO and lemon juice
  • Vitamin C: maximum (zero cooking)
  • Citric acid from lemon increases iron absorption by 3-6x

3. Wild Garlic Soup (Partial Method)

  • Add leaves only at the end of cooking, with heat off
  • Preserves 60-70% of vitamin C
  • Add a squeeze of lemon at the table to recover some lost vitamin C

4. Sautéed Wild Garlic (Minimal Method)

  • Sauté 1-2 minutes on high heat
  • Preserves 40-50% of vitamin C
  • Better raw, but still valid

Golden tip: The wild garlic + lemon combination is not just about taste — it's nutritional science. Citric acid from lemon increases non-heme iron (plant iron) absorption by 300-600%, making wild garlic a much more effective iron source.

Frequently Asked Questions (FAQ)

Does wild garlic really have more vitamin C than lemon?

Yes. Per 100g of fresh product, wild garlic contains about 150mg of vitamin C versus lemon's 53mg — nearly 3 times more. However, lemon is more easily consumed in larger quantities (a whole lemon vs a handful of leaves), so in practice the per-serving intake can be similar.

How much wild garlic do I need to eat to meet the RDA for vitamin C?

The RDA for vitamin C is 90mg/day (men) and 75mg/day (women). With just 50-60g of fresh wild garlic leaves (about a handful), you cover your daily requirement. In practice, a salad or pesto with wild garlic is more than sufficient.

Does cooking destroy vitamin C in wild garlic?

Yes, partially. Vitamin C is heat-sensitive. Prolonged cooking (10+ minutes boiling) can destroy 50-70% of vitamin C. To preserve it maximally, eat wild garlic raw or add it only at the end of cooking.

Can I use dried wild garlic for vitamin C?

No. Drying destroys most of the vitamin C (up to 80-90%). Dried wild garlic retains minerals and allicin, but for vitamin C you must use fresh leaves.

Can wild garlic and lemon be consumed together?

Yes, it's the ideal combination. Citric acid from lemon stabilizes vitamin C and increases iron absorption from wild garlic by 300-600%. A wild garlic pesto with lemon, or a salad dressed with oil and lemon, is the perfect nutritional combination.

Where can I find reliable nutritional data on wild plants?

The most reliable sources are: - USDA FoodData Central (official US database) - INRAN (Italian National Research Institute for Food and Nutrition) - PubMed (peer-reviewed scientific studies) --- Next article: Template B — "Is Raw Plantain Safe to Eat?" (Tier 1, vol 100, KD 8)
