Sharp, aromatic, and full of character — onions are more than a kitchen staple.
They’re rich in vitamins, minerals, and natural compounds that support heart health, immunity, and digestion.
In addition, onions contain unique antioxidants that help fight inflammation and promote long-term wellness.
🌸 Main Vitamins in Onions

Folate supports red blood cell formation and tissue repair, essential for cellular health and energy balance.
Other B Vitamins (B1, B2, B3, B5)
These B vitamins help convert nutrients into energy and support the nervous system and metabolism.
Vitamin E
Vitamin E acts as an antioxidant that helps protect skin cells and promotes cardiovascular health.
Vitamin K
