Origin & History
Fennel bulb (Foeniculum vulgare) is native to the Mediterranean region and now cultivated globally, thriving in warm, well-drained soils with full sun exposure. Unlike its seeds, the bulb is particularly rich in prebiotic fiber, polyphenols, and essential nutrients. Its unique composition makes it a powerhouse for gut health, cardiovascular function, and metabolic balance in functional nutrition.
“Fennel bulb has been a staple in Mediterranean, Ayurvedic, and Traditional Chinese Medicine (TCM) traditions for centuries. Ancient Greeks and Romans valued it for metabolic endurance, while Ayurvedic practitioners prescribed it for hormone balance and detoxification. Its historical use underscores its long-recognized benefits for digestion, cardiovascular health, and respiratory support.”Traditional Medicine

What is the recommended dosage and is fennel bulb safe?
Consuming 100–200g of fresh fennel bulb daily is safe for most adults. Fennel extract dosages of 100–500mg/day have been used in clinical trials. Avoid therapeutic doses during pregnancy due to estrogenic activity, and use caution with estrogen-sensitive conditions or anticoagulant medications.
What are the proven health benefits of fennel bulb?
Clinical trials support fennel for reducing menstrual pain (dysmenorrhea), alleviating digestive symptoms like bloating and IBS, and providing antioxidant protection. Its prebiotic fiber supports gut microbiome diversity. Epidemiological and preclinical data also suggest cardiovascular and anti-inflammatory benefits, though more large-scale human trials are needed.
