Deep Dive
Scallions are nutritional overachievers. Despite their size, they are loaded with Vitamin C, a crucial antioxidant that protects your cells from damage and boosts your immune defense. They are also one of the best dietary sources of Vitamin K, a nutrient often overlooked but vital for proper blood clotting and maintaining strong bones.
The real magic, however, lies in the organosulfur compounds (like allicin) and the flavonoid Quercetin. These bioactive compounds act as nature’s detoxifiers. They help reduce oxidative stress in the body, which lowers the risk of chronic diseases like heart disease. Quercetin, specifically, acts as a natural antihistamine and anti-inflammatory agent, potentially easing allergy symptoms and protecting your blood vessels.
Natural Food Sources
Scallions are the star here, but they share the spotlight with other nutrient-dense greens.
| Food | Amount | % DV |
|---|---|---|
| Scallions (Raw) | 1 cup (100g) | 20% Vitamin C, 25% Vitamin K |
| Kale | 1 cup (raw) | 68% Vitamin K |
| Spinach | 1 cup (raw) | 121% Vitamin K |
| Red Bell Pepper | 1 cup (chopped) | 190% Vitamin Vitamin C |
Supplementation
Scallions are best consumed as a whole food. You do not typically find "Scallion Supplements" on the shelf. However, you can find Onion Extract supplements which concentrate the quercetin and sulfur compounds.
Usage: Eating 1/2 cup of raw or lightly cooked scallions daily is sufficient to gain benefits. The green tops contain the highest concentration of vitamins compared to the white bulb.

Safety & Side Effects
Scallions are generally very safe for most people. However, because they are high in Vitamin K, individuals taking blood thinners (like Warfarin/Coumadin) should maintain a consistent intake to avoid interfering with their medication.
Chemical Safety: Scallions contain thiosulfate, which is toxic to dogs and cats. Never feed scallions or onions to pets.
